Yini Echaza I-IEC 61643-11 Uhlobo 1 SPD?

Ngokusho kwe- I-IEC 61643-11 Uhlobo 1 lwe-SPD ejwayelekile, la madivayisi kumele amelane Ukuphakama kwesimo segagasi esingu-10/350 µs, elingisa ugesi wokushaya kombani okuqondile.

Ngokungafani namadivayisi okuvikela angezansi, Uhlobo 1 idivayisi yokuvikela ukukhuphuka kwe-SPD ifakiwe emnyango wesevisi noma ebhodini lokusabalalisa eliyinhloko ukuze isebenze njengengqimba yokuqala yokuzivikela ngokuphelele uhlelo lokuxhumanisa ukuvikelwa kokukhuphuka.

Ezinhlelweni zamandla zezimboni zanamuhla, isivikelo sokuqhuma kombani kuqinisekisa ukuthi imisinga yokukhanya kombani iqondiswa phansi ngokuphephile ngaphambi kokuba isakazeke ijule kakhulu kunethiwekhi kagesi.

Izixazululo zezinga lezimboni zokuvikela ukungena zingatholakala kochwepheshe izinhlelo zokuvikela ukukhuphuka ezisetshenziswa engqalasizinda, ezitshalweni zokukhiqiza, kanye nasezikhungweni zamandla avuselelekayo.

Ama-SPD ohlobo 1 avikela kanjani amaphaneli okungena kwesevisi?

A isivikelo sokungena kwensizakalo isebenza ngokuphambukisa imisinga yokuphambuka kombani kusukela entanjeni yamandla iye ohlelweni lokufaka phansi.

Lawa madivayisi aklanywe ngokukhethekile ukuze amelane namandla aphezulu okuqhuma ahlobene ne- Isivikelo sokwanda kwesimo samagagasi esingu-10/350 µs ukuhlolwa okudingekayo ngokwezindinganiso ze-IEC.

Inqubo Yokukhipha Ugesi Ngombani

Uma umbani ushaya umugqa kagesi noma isakhiwo esiseduze, imisinga emikhulu yokudonsa ingangena ekufakweni kukagesi.

I isivikelo sokuqhuma kwamandla kagesi ombani kusebenze izingxenye zokuvikela zangaphakathi ezifana nalezi:

• izikhala zenhlansi

• amapayipi okukhipha igesi (i-GDT)

• i-varistors ye-metal oxide enamandla amakhulu (MOV)

Lezi zingxenye zihambisa amandla okuqhuma ngqo emhlabeni, zivimbela ugesi ongaphezu kwamandla awonakalise imishini engezansi komfula.

A idivayisi yokuvikela ukukhuphuka kwephaneli eyinhloko ngakho-ke isebenza njengesigaba sokuqala se Uhlobo 1 Uhlobo 2 Uhlobo 3 Isivikelo se-SPD, ukuqinisekisa ukuthi amandla okwanda ancishiswa kancane kancane kulo lonke uhlelo.

Izici Zobuchwepheshe Ezijwayelekile Zohlobo 1 SPD

Lokhu Amadivayisi okuvikela ukukhuphuka kwe-Iimp zibalulekile ekufakweni okunezinhlelo zokuvikela umbani zangaphandle noma ezitholakala ezindaweni ezinabantu abaningi bombani.

Onjiniyela bavame ukufaka izinto ezihlanganisa umbani kanye nokuvikela ukukhuphuka komoya endaweni eyodwa. Amadivayisi okuvikela ukukhuphuka kohlobo 1+2.

Zisetshenziswa kuphi izivikelo zokunyuka kwe-DIN Rail Type 1?

A Isivikelo sokuhlasela kwesitimela se-DIN Uhlobo 1 yenzelwe ukufakwa ngaphakathi kwamaphaneli okusabalalisa kagesi kusetshenziswa ukufakwa kwesitimela se-DIN okujwayelekile.

Lokhu kulungiselelwa kuvumela ukuhlanganiswa okulula kuma-switchboard ezimboni kanye namakhabethe kagesi.

Izicelo Ezivamile

Ukufakwa okujwayelekile kufaka phakathi:

• izinhlelo zokusabalalisa amandla ezimboni

• amabhodi amakhulu okushintshanisa izakhiwo zezentengiselwano

• izikhungo zedatha kanye nengqalasizinda yezokuxhumana

• izinhlelo zamandla ze-photovoltaic

• ingqalasizinda yezokuthutha

Lezi zindawo zidinga ukuthembeka ukuvikelwa kokuqhuma kombani wezimboni ukuvimbela isikhathi sokungasebenzi kanye nomonakalo wemishini.

Idizayini eklanywe kahle idivayisi yokuvikela umbani kuqinisekisa ukuthi imisinga yokukhanya kombani iqondiswa ngokuphephile ngaphambi kokuba ifinyelele imishini kagesi ebucayi.

Ekuklanyweni kobunjiniyela obusebenzayo, la madivayisi asebenza ndawonye namayunithi okuvikela angaphansi komfula njengengxenye ye- uhlelo lokuxhumanisa ukuvikelwa kokukhuphuka.

Ungaqinisekisa Kanjani Ukuhambisana Kwe-SPD Yohlobo 1 Nezinhlelo ze-TN-S noma ze-TT?

Ukukhetha i-SPD efanele kumele kucabangele ukucushwa kwesisekelo sesistimu.

Ukuhlelwa okuhlukene komhlabathi kudinga izakhiwo ezahlukene zezintambo ze-SPD ukuqinisekisa ukukhishwa komoya ogelezayo okuphephile.

Izinhlelo Zomhlaba Ezivamile

Ukufakwa kukagesi okuningi kusebenzisa okunye kokucushwa okulandelayo kokusekela phansi:

• Uhlelo lwe-TN-S

• Uhlelo lwe-TT

Zombili zidinga izindlela ezithile zokuxhuma ze-SPD ukuze kugcinwe ukusebenza kahle kwesisekelo.

Ukucushwa kwe-SPD kwezinhlelo ezahlukene zokufaka umhlaba

Ukukhetha okuhambisanayo Ukuvikelwa kokuphakama komhlaba kwe-TN-S TT ukucushwa kuqinisekisa ukuthi umbane ukhishwa ngokuphephile ngaphandle kokudala umehluko oyingozi ongaba khona ngaphakathi kokufakwa.

Onjiniyela abaklama izinhlelo zokuvikela umbani bavame ukubhekisela emikhubeni yobuchwepheshe yokufaka efana Umhlahlandlela wokufaka we-SPD yohlobo 1 ukuqinisekisa ukuhlanganiswa okufanele kohlelo.

Isiphetho

A Isivikelo sokwanda kohlobo 1 idlala indima ebalulekile ekuvikeleni ukufakwa kukagesi emisingeni yombani eqondile engena ngezintambo zikagesi.

Njengoba kuchazwe yi- I-IEC 61643-11 Uhlobo 1 lwe-SPD, lawa madivayisi kumele amelane nemisinga enamandla amakhulu emele i- Ukuphakama kwesimo segagasi esingu-10/350 µs.

Uma ifakiwe emnyango wesevisi noma ebhodini lokusabalalisa eliyinhloko, Uhlobo 1 idivayisi yokuvikela ukukhuphuka kwe-SPD amayunithi asebenza njengesigaba sokuqala sesu lokuvikela elihlanganisiwe, akha isisekelo sendlela ethembekile Uhlobo 1 Uhlobo 2 Uhlobo 3 Isivikelo se-SPD ukwakheka kwezakhiwo.

Ngokuqinisekisa ukuhambisana Ukuvikelwa kokuphakama komhlaba kwe-TN-S TT izinhlelo futhi zihlanganiswe ohlelweni oluphelele lokuxhumanisa ukuvikelwa kokukhuphuka, onjiniyela bangakwazi ukuvikela ngempumelelo ingqalasizinda kagesi yezimboni.

Imibuzo Evame Ukubuzwa
