Indlela yokukhetha umthamo wokuphulwa kwebhokisi ye-breaker circuit?

Ukuqhawuka kwamandlaibhokisi Uhlobo lwebreakeribhekisela kumbane omfutshane onokuthi uphulwe yi-breaker circuit kwisiseko sokuqinisekisa ukuba akukho monakalo xa kukho impazamo yesiphaluka esifutshane kwinkqubo yesekethe.Umthamo wokuqhawula kwakhona umgwebo wokukhusela ukusebenza kwefreyimu yesiphaluka.Indlela yokukhetha umthamo wokuphulwa kwe-breaker circuit?Ngaba inkulu ingcono?Makhe siyihlalutye
Umsebenzi webhokisi ye-circuit breaker kukudibanisa, ukuthwala kunye nokukhupha i-current evamile.Ngexesha elifanayo, inokuphinda idibanise, ithwale kwaye ikhuphe i-fault current phantsi kweemeko ezingaqhelekanga (i-overload and short circuit).Ikhono lokuqhawula i-fault current ngumgangatho obalulekileyo wokugweba ukusebenza kwe-circuit breaker, oko kukuthi, ukuphulwa kwamandla ombane wesiphaluka.Okwangoku, amandla okuqhawuka kwesaphuli sesekethe sinezalathisi ezimbini, ezizezi:
1. Ukulinganisa ukusebenza kwe-short-circuit breaking capacity ics of box circuit breaker: ireyithingi yokusebenza ye-short-circuit current apho umenzi angayiphula phantsi kweemeko ezichaziweyo phantsi kombane ohambelanayo.Ngokukodwa, emva kokuba i-circuit breaker inokunqumla i-short-circuit current, i-breaker circuit isenokusetyenziswa ngokuqhelekileyo.
2. Umda olinganiselweyo wokuqhawula umthamo we-ICU: umda we-short-circuit yangoku ukuba umenzi we-breaker circuit breaker unokwaphula phantsi kweemeko ezichaziweyo phantsi kwe-voltage ehambelanayo.Okokuthi, emva kokuba i-circuit breaker inqamule i-short-circuit current, ukuba ivuliwe kwaye ivalwe kwakhona, ayinakuphinda isetyenziswe ngokuqhelekileyo.
Umthamo wokuphulwa kwebhokisi yebhokisi yesekethe ineenkcazo ezininzi ezahlukeneyo kunye neeparitha.Ngokuqhelekileyo, ubukhulu bomthamo wokuphulwa, ukuphakama kokhuseleko, kodwa ixabiso le-breaker circuit kunye nomthamo omkhulu wokuqhawula liya kuba phezulu.Ngoko ke, kuyimfuneko ukukhetha i-breaker circuit kunye nomthamo ofanelekileyo wokuphulwa kwinqanaba lokuqinisekisa ukhuseleko lwezixhobo, ukwenzela ukugcina uhlahlo lwabiwo-mali oluthile.
