Ukufakwa Kwangaphakathi kwe-BESS: Kungavikeleka?

Ukufakwa kwe-BESS kwasendlini kungase kuphephe, kodwa akufanele nanini kuthathwe njengento elula kagesi-yokuthuthukisa igumbi. Isistimu yesitoreji samandla ebhethri ye-lithium-ion efakwe ngaphakathi kwebhilidi kufanele ihlelwe eduze kokuphepha komlilo, ukuthikamezeka kwe-thermal, umoya, ukutholwa kwegesi, ukufinyelela esimweni esiphuthumayo, ukuvala ugesi, nokusayina{3}}kuziphathimandla zendawo ezinegunya (AHJ). Thola okukodwa kwalezo okungalungile futhi indawo inganqatshwa sekwephuzile kuphrojekthi, ngemuva kokuthi okokusebenza sekuvele ku-odiwe.

I-lithium-ion BESS ingafakwa endlini, kodwa kuphela uma isistimu ikuhluI-UL9540, esekelweI-UL 9540Aumlilo-idatha yokuhlola efana nesakhiwo sangaphakathi esihlongozwayo, esihlaliswe endaweni eshisiwe eshisiwe{1}}egumbini elihlukanisiwe elinomoya wobunjiniyela kanye nokutholwa kwegesi, eliboshelwe ekuvaleni kwesimo esiphuthumayo namasistimu ama-alamu omlilo{2}}, futhi labuyekezwa futhi lagunyazwa yi-AHJ kanye nomnyango wezomlilo ngaphansi kwendinganiso efana nalena.I-NFPA 855. Ukufakwa endlini akuphephile ngokuzenzakalelayo noma akuyingozi kakhulu kunengaphandle - kuphephile kuphela uma izimo zesakhiwo zisekela idizayini yokuphepha.

Ingabe i-Lithium-Ion BESS Ingafakwa Ngaphakathi Ngendlu Ngokuphephile?

Yebo - lapho isistimu, igumbi, umoya omncane, ukuvikela umlilo, ukuqapha, nezinqubo zesimo esiphuthumayo zihlanganiswa ndawonye njengomklamo owodwa wokuphepha kunokuba zihlanganiswe njengezingxenye ezihlukene.

Isimiso esiyinhloko siwukuthi ukuphepha akukwazi ukuhlala emshinini owodwa. Uhlelo lokucindezela lulodwa alwanele. Uhlelo lokuphatha ibhethri lulodwa alwanele. Ukufakwa okuphephile kwasendlini kuncike ezendlaleloni ezimbalwa ezisebenza ngesikhathi esisodwa:

• Isistimu yokugcina amandla ebhethri esohlwini lwezinga lokuphepha elidingekayo,{0}}nedatha yokuhlola umlilo ngemuva kwayo
• Igumbi lebhethri elizinikele noma indawo evalekile efanele okokusebenza
• Ukwehlukaniswa komlilo ezindaweni ezihlala abantu neziseduze
• Ukuphatha okushisayo okulawula izindawo ezishisayo ngaphambi kokuthi kugeze
• Isu lokungenisa umoya negesi{0}}elidizayinelwe izimo zokwehluleka, hhayi nje ukupholisa
• Ukuvala shaqa okuphuthumayo nokuhlanganiswa kwe-alamu nesakhiwo
• Ukufinyelela okucacile kwabasebenzi bokulungisa kanye nabaphenduli bokuqala
• Iphakheji lamadokhumenti i-AHJ, umshwalense, kanye nomnyango wezomlilo bangabuyekeza ndawonye

Emakethe yase-US, i-NFPA 855, i-International Fire Code (IFC), UL 9540, kanye ne-UL 9540A yizithenjwa ezivela ngokuphindaphindiwe phakathi nokubuyekezwa kwe-ESS. Uhlelo lwamanje lweI-NFPA 855, indinganiso yokufakwa kwamasistimu okugcina amandla amile, inguqulo yango-2026, futhi ibeka izimfuneko eziyisisekelo ezihlanganisa ukutholwa nokucindezela umlilo, ukulawula ukuqhuma, umoya wokukhipha umoya, ukutholwa kwegesi, kanye nokubaleka okushisayo - ngqo kwezinto iphrojekthi yasendlini ehlala noma efela kuzo. Lesi sihloko sigxile ohlakeni olujwayelekile lokubuyekeza lwase-US; amaphrojekthi kwezinye izimakethe kufanele aqinisekise amakhodi endawo afanayo omlilo, ugesi, namakhodi wokwakha, ngoba imingcele nemithetho yokuhlala iyahlukahluka ngezwe, isifunda, nedolobha.

Lapho Ukufakwa Kwe-BESS Yangaphakathi Kwenza Kunengqondo

Ukufakwa kwasendlini kuvame ukucatshangelwa lapho ukuthunyelwa kwangaphandle kungenzeki noma kuyeka kakhulu uhlelo lokusebenza. Abashayeli abavamile bahlanganisa isikhungo sedatha esifuna isitoreji esiseduze ne-UPS yayo kanye nemithwalo ye-IT ebalulekile, ifektri edinga amandla ayisipele eduze kwemishini yokukhiqiza, isakhiwo sezentengiselwano noma sasemadolobheni esingenazo izigxivizo zangaphandle ezisebenzisekayo, isibhedlela noma isikhungo esifuna isitoreji esiphakathi nendawo esivikelwe, noma indawo yokushaja ye-EV edinga ukubhafa kwesidingo eduze kwegumbi layo likagesi.

Lezi akuzona izimo eziguqulekayo. Esikhungweni sedatha, isibonelo, inani lokungena endlini lifushane, izindlela zamandla ahlanzekile eziya ku-UPS kanye ne-switchgear nokusebenzisana okuqinile ngokuqapha kwesikhungo - kodwa lokho kusondela kuphakamisa ibha ekuhlukaniseni igesi nokufinyelela okuphuthumayo, ngenxa yokuthi igumbi lebhethri manje liseduze nezikhala abantu abangenakuzilahlekela. Izinsiza ezikala isitoreji eduze nemithwalo ebalulekile ye-IT ngokuvamile ziqala ngokwenza imephu ukuthi kanjaniI-BESS isekela amandla esikhungo sedathangaphambi kokunquma ukuthi igumbi elingaphakathi elilungisiwe noma iyunithi ye-modular ilingana kangcono.

Ama-retrofits aziphatha ngendlela ehlukile futhi. Kuphrojekthi yefekthri ye-retrofit, isici esikhawulelayo akuvamile ukuba sibe umthamo webhethri - ngokuvamile kuba ukuthi igumbi elikhona lingakwazi yini ukusekela umzila wokuphuma kwamanzi, ukulayishwa kwaphansi, nokukhishwa kokulungisa ngaphandle komsebenzi omkhulu wesakhiwo. Ukubekwa kwasendlini kunganciphisa ukugijima kwekhebula kugiya lokushintsha noma imithwalo ebalulekile, kodwa kuphela lapho isakhiwo singathwala khona izidingo zokuphepha eziza nayo.

Lapho Ukufakwa Kwangaphandle Kungaba Ngcono

I-Outdoor BESS ivamise ukuba lula uma isayithi linendawo, ukufinyelela okucacile, amabanga amukelekayo okuhlehliswa, kanye nobunkimbinkimbi bokuhlanganisa{0}}kwesakhiwo esiphansi. Ngenxa yokuthi amagesi aphumayo nokushisa kungahlakazeka emoyeni kunokuba kunqwabelene endaweni evalekile, ukubekwa kwangaphandle kunganciphisa ukukhathazeka okuthile kwegesi-kungase kwenze kube lula{3}}ukufinyelela kophendulayo - nakuba lokhu kuncike ekwakhiweni kwendawo ebiyelwe, izithiyo, ukwakheka kwesayithi, izimo zomoya, kanye nohlelo lomlilo akumele lufundeke ngokuzenzakalelayo{5}.

Ukufakwa endlini kufanele kubhekwe kahle okwesibili uma igumbi lingenakuhlukaniswa nezindawo okuhlala abantu kuzo, igesi ekhipha igesi ingakwazi ukuthuthwa ngendlela ephephile, ukufinyelela komlilo{0}}kuvinjelwe, indawo ephansi ayikwazi ukuthwala umthwalo, izindawo zokulungisa ziqine kakhulu, noma umnikazi webhilidi engakwazi ukuzibophezela ekuhloleni okuqhubekayo nasezinqubweni eziphuthumayo. Umgomo awukona ukuphoqelela isistimu ngaphakathi endlini - uwukukhetha indawo esebenzisekayo ephephe kunazo zonke yohlelo lokusebenza. Lapho indlela yangaphandle isebenza khona, ihlanganisiweiKhabhinethi yangaphandle BESSingakwazi ukweqa ingxenye enkulu yegumbi elingaphakathi, umoya omncane, kanye nobunjiniyela bokuhlukanisa ngokuphelele.

Izidingo zegumbi le-BESS langaphakathi

Iningi lokusesha-abathengi besiteji bafuna okungaphezu kweseluleko - bafuna ukwazi ukuthi yini edingekayo ngempela. Izidingo ziyahlukahluka ngendawo, uhlobo lokuhlala, umthamo wamandla, nekhemistri yebhethri, futhi i-AHJ inokuhumusha kokugcina. Sesikushilo lokho, izinto ezilandelayo zivela cishe kuyo yonke iphrojekthi ye-lithium-yasendlini yasendlini futhi kufanelekile ukuqinisekiswa ngaphambi kokuthi ku-odwe okokusebenza:

• Umlilo-ulinganise ukuhlukanaezindaweni ezihlala abantu kanye namakamelo aseduze, lapho kudingwa khona ngekhodi kanye nokuhlaziywa kokunciphisa ubungozi. Kungani kubalulekile: lesi yisithiyo esithenga isikhathi sokuphuma nokusabela uma iyunithi yehluleka.
• Ukulayisha phansi kanye nomthamo wesakhiwongesisindo sohlelo oluphelele. Yini engahambi kahle: isakhiwo esilingana nomdwebo kodwa silayishe ngokweqile i-slab esikhona siphoqa ukuklama kabusha.
• Ukusetshenziswa okuzinikele kwegumbi- asikho isitoreji esabelwe, izinto ezivuthayo, noma izinto zokusebenza ezingahlobene. Kungani kubalulekile: umthamo kaphethiloli owengeziwe kanye nemfuhlumfuhlu kuyingozi kokubili ikesi lomlilo nokufinyelela ezimweni eziphuthumayo.
• Izimvume zokusebenza kanye nezinsizakalonxazonke zekhabhinethi, kanye nendlela ecacile yokushintshwa kwamamojula. Yini engahambi kahle: uhlelo olunganakekelwa ngokuphephile luba olungaphephile empilweni yalo.
• Ukufinyelela okuphuthumayo okuqondile noma okumakwe ngokucacilekwabaphenduli bokuqala, abanezilawuli zokuvala shaqa ezimakiwe nezibani eziphuthumayo.
• Ukuvikelwa ekungeneni kwamanzi, umthelela wemishini, nokungena okungagunyaziwe, okuhlanganisa nokulawula ukufinyelela nezimpawu.

Izidingo Zokungena komoya kanye Negesi ze-BESS Yangaphakathi

Ukungena komoya kwe-BESS yasendlini akuyona inkinga efanayo nokupholisa igumbi elivamile. Phakathi nokuhluleka kwamaseli, amabhethri angakhipha amagesi avuthayo nanobuthi ngaphambi noma phakathi nomlilo. Egunjini elivalekile lawo magesi anganqwabelana aze afike eqophelweni lobuthi, ukulahleka kokubonakala, kanye nokuwohloka - yingakho ukuphuphuma komoya, ukutholwa kwegesi, kanye nokukhipha umoya kufanele kwenziwe ngesikhathi esifanayo nesisetshenziswa nesakhiwo segumbi, singaboshelwa ngemva kwalokho.

Umklamo osebenzayo kufanele uphendule imibuzo ethile, hhayi nje uhlu lwezingxenye: ukususwa kokushisa ekusebenzeni okuvamile; izindlela zokuqeda izimo eziphuthumayo ezinikezelwe; umqondo ovuthayo lapho umtshina wegesi usebenza; ukucindezela nokugeleza komoya; ukuhlukaniswa nezindawo zokwakha; kanye nokuxhumana ne-alamu yomlilo nezinhlelo zokuvala shaqa. Ngokuqondile, idizayini kufanele ichaze ukuthi ubani owamukela i-alamu, noma ukungena komoya kuqala ngokuzenzakalelayo, noma ngabe i-BESS iyacisha, nokuthi ingabe abaphenduli bangakwazi ukufunda amaleveli egesi bekude ngaphambi kokuba noma ubani avule umnyango - konke kuxazululiwe ngaphambi kokuvula, okungatholakalanga ngesikhathi sesigameko. Njengoba ukugeleza komoya, ukuphatha okushisayo, nokuphatha igesi kuncike komunye, amaqembu ngokuvamile anqumaindlela yokukhetha isistimu yokupholisa ye-BESSngokuhambisana nohlelo lokungena komoya kunokuba ngemva kwalo.

Izingozi Eziyinhloko Zokuphepha Ngaphakathi Kwezakhiwo

I-Thermal Runaway kanye Nokusabalalisa

I-Thermal Runaway - iseli elingena endaweni engalawuleki,{1}}yokuzishisa ngokwayo engasakazekela kumaseli angomakhelwane - iyingozi emaphakathi yamasistimu e-lithium-i-ion. Ngaphakathi, ukulawulwa kokusabalalisa kubaluleke nakakhulu, ngoba ukwehluleka kungafinyelela ngalé kwekhabhinethi ekamelweni, umoya wesakhiwo, imishini eseduze, kanye nezimo abaphenduli ababhekana nazo. I-UL Solutions iyachazaI-UL 9540A njengendlela yokuhlola yokuhlola ukusakazeka komlilo obalekayo oshisayokumasistimu okugcina amandla ebhethri, kanye nohlelo lwayo lwesi-6 lwengeze ngokukhethekile ukufakwa{1}}isimo sezinga lesimo esithatha isimo sokuthunyelwe{2}}sokucekela phansi futhi sihlole umklamo wendawo ebiyelwe, amabanga okuhlukaniswa, kanye - namasistimu angaphakathi - ukuthi kusebenza kanjani-ukucindezelwa okusekelwe esakhiweni.

Ukuqoqwa Kwegesi kanye Nokwehliswa kweflagration

Isigameko sango-2019 sikaMcMicken eSurprise, e-Arizona sihlala siyireferensi yokuthi kungani ukuphatha igesi yasendlini kungeyona inketho. Ngokusho kweI-Fire Safety Research Institute ibika ngalesi sigameko, ukwehla kokushisa okushisayo ku-lithium engu-2.16 MWh{1}}ion ESS kuholele ekulimazeni okulimaza kabi izicishamlilo ezine lapho indawo ebiyelwe ivulwa amahora amaningi kuphendulwa. Isistimu yokucindezelwa-ye-ejenti ehlanzekile isheshe yaphuma, kodwa ayenzanga lutho ukumisa ukushisa okushayela imoto ebalekayo noma ukulawula igesi evuthayo eyakha ngaphakathi - kwenhlanganisela ukuthi ukucindezela kukodwa akuzange kuklanyelwe ukuphatha. Isifundo samaphrojekthi asendlini siqondile: ukutholwa, ukucindezelwa, ukungena komoya, nokulawula ukuqhuma kufanele kusebenze njengesistimu, futhi abaphenduli badinga ukubonakala okukude kulokho okwenzekayo ngaphambi kokuba bangene.

Ukwehlukaniswa Komlilo, Ukufinyelela, kanye Nesikhala Sokulungisa

Igumbi lebhethri aliyona ikhabethe likagesi eliyisipele. Idinga indawo yokusebenza okuphephile, ukufinyelela kwesevisi, ukungena kwezimo eziphuthumayo, kanye{1}}nempendulo yomnyango - yingakho umlilo{3}}ulinganisele ukwakhiwa lapho kudingeka, ukufinyelela okulawulwayo, indawo yokusebenza ecacile, izilawuli ezimakiwe zokuvala, nokuvikelwa emanzini kanye nomthelela konke kuyingxenye yomklamo kusukela ekuqaleni, hhayi njengokulungiswa kwakamuva.

Ukuhlanganisa Ugesi kanye Nokulawula Ukuvala shaqa

I-BESS yasendlini ngokuvamile ibophela ku-switchgear, ama-transformer, i-solar PV, amajeneretha, okokusebenza kwe-UPS, amashaja e-EV, noma imithwalo yesikhungo. Lokho kuhlotshaniswa kufanele kubhalwe ngaphambili - kwemidwebo yomugqa owodwa-, izilungiselelo zokuvikela, ukubeka phansi kanye nokubopha, amandla ezimo eziphuthumayo-avaliwe kunengqondo, izinqubo zokuhlukanisa, i-arc{4}}ukulebula kwe-flash, nokuhlanganiswa nesikhungo i-EMS noma i-SCADA - ukuze bobabili abasebenzi besikhungo namaqembu ezimo eziphuthumayo babone ukuthi bangawahlukanisa kanjani ama-alamu abalulekile futhi bazi.

I-UL 9540 vs UL 9540A

Lawa magama amabili adala ukudideka okuningi kokuthengwa kwempahla kunanoma iyiphi enye into kuphrojekthi yasendlini.I-UL9540yisitifiketi sokuphepha (uhlu) lwesistimu yokugcina amandla nezinto zayo.I-UL 9540Aisivivinyoindlelaekhiqiza umlilo-idatha yokusabalalisa - ayikhiqizi ukufakwa kuhlu kokudlula/kwefail, futhi ayikho into efana nesistimu ethi "UL 9540A certified" noma "UL 9540A ohlwini".

Kumthengi, umehluko awuwona wezemfundo. Isimangalo somphakeli se-"UL 9540A eqinisekisiwe" siyifulegi elibomvu, ngoba ukulungiselelwa okuhloliwe yikho okubalulekile, hhayi ilebula. Buza isimo sangempela sokufakwa kuhlu kwe-UL 9540, imibiko yokuhlolwa kwe-UL 9540A, ileveli yokuhlola, ukulungiselelwa kwesistimu ethile eyahlolwa, kanye - ngokujulile - nokuthi lokho kulungiselelwa okuhloliwe kufana nesakhiwo sakho sangaphakathi esihlongozwayo. Ukushintsha isikhala sekhabhinethi, ukuhlelwa kwegumbi, ukuqagela komoya, noma ikhemistri yebhethri kunganciphisa ukubaluleka kwedatha yokuhlola. Isimangalo somphakeli asanele; ukucushwa okuhloliwe kuwubufakazi. Uma wakha uhlu lwezimfuneko zebhidi, kuyasiza ukuqonda kusenesikhathikungani isitifiketi se-UL sibalulekile ku-BESSfuthi yiziphi izincwadi ezithathwa njengobufakazi.

Imibhalo Yemvume ye-BESS Yangaphakathi Yokubuyekezwa kwe-AHJ

Ngephrojekthi yasendlini, faka i-AHJ kanye nomnyango wezomlilo kusenesikhathi. Ukubuyekezwa kwesiteji-kwakamuva kulapho amathimba ethola khona ukuthi igumbi, isikhala, ukushaywa umoya, noma amadokhumenti akwamukelekile - okuholela ekwakhiweni kabusha, ukutholwa okungeziwe, noma ukwenqatshwa ngokuphelele kwendawo. I-NFPA 855 inikeza i-AHJ igumbi lokubuyekeza izinto ezinjengokuhlaziywa kokunciphisa ubungozi, izinhlelo zokusebenza eziphuthumayo nezinhlelo zokusabela,{5}imininingwane yesistimu yokuphepha{5}, kanye nemiphumela yokuhlolwa komlilo noma ukuqhuma, ngakho iphakethe ledokhumenti kufanele lihlanganiswe ukuze kuphendule lezo ngaphambi kokuqala kokwakhiwa.

Iphakheji elijwayelekile lokuthunyelwa kwasendlini lihlanganisa: imininingwane yomkhiqizo kanye nemanuwali yokufaka; Ulwazi lohlu lwe-UL 9540 lapho kufanele khona; umbiko wokuhlola we-UL 9540A noma idatha yokuhlola yomlilo efanayo-nomlilo ofanayo; amakhemikhali ebhethri kanye nemininingwane yamandla; umdwebo kagesi-womugqa owodwa; isakhiwo sendawo kanye negumbi; umlilo-imininingwane yokuhlukanisa; idizayini yokungena komoya kanye negesi-indlela yokuthola igesi; I-alamu ye-BMS ne-EMS; inqubo yokuvala ucingo oluphuthumayo; ukuhlaziywa kokunciphisa ubungozi lapho kudingeka khona; uhlelo lokusabela ezimeni eziphuthumayo; uhlelo lokusebenza; incwadi ye-O&M; kanye nohlelo lokuyeka ukusebenza noma lokugaywa kabusha lapho kudingeka. Iphuzu lephakheji ukuthola i-AHJ, umshwalense, umnikazi, i-EPC, kanye nomphakeli babuyekeze ukuqagela okufanayo ngaphambi kokuba noma ubani aphule phansi.

Ithebula Lezidingo Zokufakwa Kwe-BESS Yangaphakathi

I-Indoor vs Outdoor BESS

Lokhu ukucatshangelwa okujwayelekile, ngaphansi kwekhodi yendawo kanye nomklamo wephrojekthi. I-Indoor BESS ayiphephile ngokwemvelo noma ayiyingozi kakhulu kuneyangaphandle - iphephile kuphela uma izimo zesakhiwo kanye nedizayini yokuphepha zisekelana.

imibuzo ejwayelekile ukubuzwa

Ingabe kuphephile ukufaka i-lithium-ion BESS endlini?

Yebo, uma iwuhlu futhi iwuhlelo oluhloliwe{0}lomlilo{0}egumbini elizinikele,{1}}elihlukaniswe umlilo{1}elinomoya omncane wobunjiniyela, ukutholwa kwegesi, ukuvalwa kwesimo esiphuthumayo, kanye nokugunyazwa kwe-AHJ. Ukuphepha kuvela ekwakhiweni okuhlanganisiwe, hhayi ekubeni ungaphakathi noma ngaphandle.

Ingabe i-UL 9540A iqinisekisa i-BESS ukuze isetshenziswe endlini?

Cha. I-UL 9540A iyindlela yokuhlola ekhiqiza idatha yokusabalalisa umlilo{2}, hhayi isitifiketi noma ukufakwa kuhlu. Uhlu lwesistimu luyi-UL 9540; umbiko we-UL 9540A usekela izinqumo zokuvumela nokubuyisela emuva, futhi ukumiswa kwawo okuhloliwe kufanele kufane nesakhiwo sakho sasendlini.

Iyiphi ikhodi elawula ukufakwa kwe-BESS kwangaphakathi e-US?

I-NFPA 855 (uhlelo lwango-2026) iyindinganiso yokuqala yokufaka, esetshenziswa eduze ne-International Fire Code, UL 9540, kanye nezichibiyelo zasendaweni. I-AHJ inokuhumusha kokugcina kwesayithi elinikeziwe.

Yini evame ukubambezela ukugunyazwa kwe-BESS yasendlini?

Ukubandakanyeka kwe-AHJ sekwephuzile, ukungena komoya okuklanywe ngemva kwesakhiwo, idatha yokuhlola ye-UL 9540A engekho noma engafani, futhi alukho uhlelo lokusabela oluphuthumayo olwabiwe yizimbangela ezivame kakhulu.

Isiphetho kanye Nesinyathelo Esilandelayo

Ukufakwa kwe-BESS yasendlini kungasekela amandla ekhophi yasenqolobaneni, ukuphathwa kwesidingo, ukuhlanganiswa kwe-solar, kanye nokushajwa kwe-EV esikhaleni-kumabhilidi avinjelwe wezohwebo nezimboni - kodwa kuphela njengesistimu-ebalulekile yokuphepha. Amaphrojekthi aphephe kakhulu anquma indawo ngaphambi kokukhetha okokusebenza, ahilela i-AHJ kusenesikhathi, khetha isistimu esohlwini futhi ehloliwe ukumiswa kwayo okufana negumbi, ukuklama komoya kanye nokutholwa kwegesi eduze kwesakhiwo, futhi isebenzise yonke imisebenzi yokuphepha ngaphambi kokuba isebenze.

Kubanikazi namaqembu e-EPC, isinyathelo esilandelayo esisebenzayo ukuqoqa izimo zesayithi negumbi, izidingo zikagesi, umthamo ohlosiwe, ikhemistri yebhethri, nendlela yekhodi yendawo, bese lokho kufakiwe kubuyekezwe kuqhathaniswa nomkhiqizo wangempela kanye nemibhalo yokuhlola. Uma ufuna lokho kuhlola ngokumelene nehadiwe ethile, yethuizixazululo zokugcina ezentengiselwano nezimboniamakhasi asethe ukucupha okuhloliwe, futhi ungakwazithumela isayithi lakho nemininingwane yesakhiwo ethimbeni lonjiniyelaukuze kufundwe okokuqala ukuthi ukufaka endlini kuyasebenza, kuyavunyelwa, futhi kuphephile yini-kumsebenzi wesikhathi eside.
