A Surge isixhobo soKhuseleko (SPD) yinxalenye ebalulekileyo kwiinkqubo zombane zala maxesha, eziyilelwe ukukhusela isixhobo kumbane odlulayo. Ezi zinto zidlulayo, zihlala zibangelwa kukubetha kombane okanye ukutshintshwa kwegridi eluncedo, zinokubangela umbane ogqithise ngesiquphe nangokuqatha. Owona msebenzi uphambili weSPD kukucutha ezi overvoltage zexeshana kunye nokuphambukisa umbane ogqithileyo okhoyo emhlabeni, ngaloo ndlela uthintela umonakalo kwizixhobo zombane ezibuthathaka kunye nokuqinisekisa ukuqhubeka kokusebenza. Indima yayo ibalulekile kulawulo lomngcipheko olubanzi kuzo zombini ezi ndawo zokuhlala kunye nofakelo lwezorhwebo.

A I-Miniature Circuit Breaker isebenza njengecandelo elibalulekileyo lokhuseleko oluzenzekelayo kwiinkqubo zokuhambisa umbane. Umgaqo wayo wokusebenza uxhomekeke kwiindlela zokufudumala kunye nemagnethi zokubona iimeko ezingaqhelekanga zangoku. Emva kokuchonga iimpazamo eziqhubekayo eziqhubekayo okanye ezimfutshane, ifowuni iphazamisa ngokukhawuleza isekethe. Esi senzo esikhawulezileyo sithintela umonakalo onokwenzeka kwi-insulation ye-wiring kunye nezixhobo ezixhunyiwe. Uyilo olusisiseko luqinisekisa ukhuseleko lokusebenza kunye nokuthembeka kwenkqubo.

Kwiinkqubo zombane zanamhlanje, ngokukodwa kwizicelo zelanga kunye nezoshishino, indima yokukhusela isiphaluka ibaluleke kakhulu. I-Dc Fuse licandelo elisisiseko eliyilelwe ukuphazamisa ngokukhuselekileyo amandla ngexesha leziganeko ezidlulayo okanye ezimfutshane. I-BYPV-63 yoluhlu lwe-fuse holder imele isisombululo esikhethekileyo kwezi ndawo eziphezulu ze-DC, ezibonelela ngesiseko esikhuselekileyo nesithembekileyo sesici esibalulekileyo se-fuse. Uyilo lwayo lujolise ekuqinisekiseni ukhuseleko lwenkqubo kunye nokuthembeka kwezixhobo ngokuququzelela ukusebenza ngokufanelekileyo kwefuse.

Ukuthembeka kunye nokusebenza kakuhle kwenkqubo ye-photovoltaic kuxhomekeke kakhulu ekusebenzeni kwamacandelo ayo okudibanisa. Isidibanisi sePv sisidibanisi sombane esikhethekileyo esilungiselelwe ukwenza amakhonkco akhuselekileyo kunye nokumelana okuphantsi kuluhlu lwelanga. Uchungechunge lwe-PV-BY-03, uhlobo olufakwe kwipaneli, lwenzelwe ukuzalisekisa le nxaxheba, ukubonelela indawo yokudibanisa ehlala ixesha elide yokudibanisa amandla avela kwiipaneli ezininzi okanye ukudibanisa kwi-inverters. Uyilo lwayo lubeka phambili ukuzinza kwexesha elide lokusebenza phantsi kweemeko ezinzima eziqhelekileyo zofakelo lwelanga.

I-Miniature Circuit Breaker (MCB) yinxalenye ebalulekileyo yofakelo lombane lwanamhlanje, ukubonelela ngokhuseleko olubalulekileyo kwiimpazamo ezigqithisiweyo kunye nezifutshane. Ngelixa i-MCB ngokwayo iyisixhobo esipheleleyo sokukhusela, ukusebenza kwayo kunokwandiswa kakhulu ngoluhlu lwezixhobo ezikhethekileyo. La macandelo enziwe ukuba adityaniswe ngaphandle komthungo kunye ne-core breaker, enikezela ngolawulo olongeziweyo, ukubeka iliso, kunye nokhuseleko lwenkqubo yolawulo yombane eyomeleleyo.

Ukusebenza okukhuselekileyo kunye nokusebenza kakuhle kwenkqubo ye-photovoltaic (PV) kuxhomekeke kumacandelo anamandla alungiselelwe ukusetyenziswa ngokuthe ngqo kwangoku (DC). Eyona nto ibalulekileyo kolu seto yiPV Isolator Switch, isixhobo esenzelwe ngokukodwa iimfuno ezikhethekileyo zokuvelisa amandla elanga. Isebenza njengendawo yokuqhawula i-manual, eyenza ukuhlukaniswa kweesekethe zombane ukuze kugcinwe, ukufakwa, okanye ngexesha leemeko eziphuthumayo, ngaloo ndlela kuqinisekiswe ukhuseleko lwabasebenzi kunye nezixhobo.
