Vacuum zesekethe breakers , okanye iiVCB, zizixhobo zokutshintsha umbane ezisebenzisa itekhnoloji yokufunxa ukuphazamisa imisinga yombane. Banikezela ngeenzuzo ezininzi ngaphezulu kwezaphuli zesekethe zemveli, kubandakanya amaxesha okuphendula ngokukhawuleza, ukugcinwa okuphantsi, kunye nobomi obude. Kweli nqaku, siza kubonelela ngenkcazo eneenkcukacha yemveliso, sichaze indlela yokuyisebenzisa, kwaye sixoxe ngeemeko esebenza kakhulu kuzo.
Ingcaciso yeMveliso
Ai-vacuum circuit breaker iqulathe ibhotile vacuum equlathe isakhiwo zoqhagamshelwano. Xa isiphaluka sivaliwe, isakhiwo soqhagamshelwano sibanjwe kwindawo yasentwasahlobo. Xa isiphaluka sivuliwe, isakhiwo soqhagamshelwano sitsalwa kude nabafowunelwa, senze i-arc. Ibhotile ye-vacuum yenzelwe ukucima i-arc kwi-vacuum, ukukhusela umonakalo kumacandelo ombane. IiVCB zifumaneka kuluhlu lobungakanani, amanqanaba ombane, kunye nokuphazamiseka kwamandla, okubenza bafanelekele iindawo ezahlukeneyo.
Ukusetyenziswa
Ukusebenzisa ai-vacuum circuit breaker yinkqubo ethe ngqo. Xa kukho impazamo kwisekethe, iVCB kufuneka ivulwe. Oku kunokwenzeka ngesandla okanye ngokuzenzekelayo, kuxhomekeke kwisicelo. Kwizicelo zezandla, iVCB inokuvulwa ngesiphatho okanye iswitshi. Kwizicelo ezizenzekelayo, abenzi boluvo babona impazamo, kwaye iVCB ivula ngokuzenzekelayo.
Okusingqongileyo
I-vacuum circuit breakers ifanelekile kuluhlu lweendawo, kubandakanywa iindawo zoshishino kunye nezityalo zamandla. Ngokuqhelekileyo zisetyenziselwa ukukhusela iijeneretha, ii-transformers kunye nezinye izixhobo zombane. Ii-VCBs zikhethwa ngaphezu kwezaphuli zesekethe eziqhelekileyo kwiindawo apho amaxesha okuphendula ngokukhawuleza ayimfuneko. Zikwafanelekile kwizicelo eziphezulu ze-voltage apho umgangatho ophezulu wokuthembeka kufuneka. IiVCBs zinolondolozo oluphantsi, nto leyo ezenza zibe zezilungele iimeko apho unikezelo lwenkonzo lunokuba ngumceli mngeni, njengezixhobo zeoyile ezikude nonxweme okanye iziza ezikude.
Iingenelo
IiVCBs zibonelela ngeenzuzo ezininzi ngaphezulu kwezaphuli zesekethe zemveli. Okokuqala, banexesha lokuphendula elikhawulezayo, elibenza bafaneleke ngakumbi kwizicelo zesantya esiphezulu. Okwesibini, zinolondolozo oluphantsi kwaye zinexesha elide lokuphila, okukhokelela kwiindleko eziphantsi ngexesha. Ekugqibeleni, basebenza ngokuzolileyo kwaye abavelisi naziphi na iigesi eziyingozi, nto leyo ebenza ukuba bakhethe ukuhambelana nokusingqongileyo.
Iingqwalasela
Xa uqwalasela i-vacuum circuit breaker, kubalulekile ukukhetha ubungakanani obufanelekileyo, inqanaba lombane kunye nokuphazamiseka kwamandla. IiVCBs zibiza kakhulu kunezaphuli zesekethe zemveli, kodwa iindleko zingqinelwa ziinzuzo zazo ezininzi. Kukwabalulekile ukuqinisekisa ukuba i-VCB ifakwe kwaye igcinwe ngokuchanekileyo ukuqinisekisa ukuba isebenza ngokufanelekileyo xa kuyimfuneko.
Ukuqukumbela
Ukuqukumbela, ii-vacuum zesekethe ze-vacuum zibonelela ngeenzuzo ezininzi ngaphezulu kwezaphuli zesekethe zesiqhelo, kubandakanya amaxesha okuphendula ngokukhawuleza, ukugcinwa okuphantsi, kunye nobomi obude. Zifanelekile kuluhlu lweendawo ezingqongileyo, kubandakanywa iziza zoshishino kunye nezityalo zamandla, kwaye zifanelekile kwizicelo zesantya esiphezulu. Xa ucinga ngeVCB, kubalulekile ukukhetha ubungakanani obufanelekileyo, inqanaba lombane, kunye nokuphazamiseka komthamo. Zisenokuba zibiza kakhulu kunezaphuli-mthetho zesiqhelo, kodwa izibonelelo zibenza babe lutyalo-mali olufanelekileyo. Ngokukhetha i-vacuum circuit breaker, unokuphucula ukhuseleko kunye nokuthembeka kweenkqubo zakho zombane.
