Iiswitshi ze-bipolar zisetyenziselwa izibane zokukhanyisa kwaye zingasetyenziselwa ukutshintshela umbane wesokethi.
Ukumiselwa ngokweemfuno, ukutshintshwa kwepali enye kunokulawula kuphela umgca omnye, kwaye i-double-pole switch inokulawula imigca emibini ngokwahlukileyo.Ukutshintsha kwepoleni enye igcina isiqingatha somthamo xa kuthelekiswa nokutshintsha kabini.Ukutshintsha kwepali enye kukutshintsha kwe-rocker elawula isebe elinye.Ukutshintsha kwepali ephindwe kabini kukutshintsha okunamaqhuqhuva amabini alawula amasebe amabini.Iswitshi yepali enye ngokubanzi ilawula i-Live wire, ngelixa i-switch ye-pali ezimbini ilawulwa ngaxeshanye ngocingo oluphilayo kunye nocingo oluyi-zero, kodwa zombini ziya kuhamba nje ukuba umthwalo ochazwe lutshintshi ugqithisiwe, odlalayo. indima yokhuseleko.
Inani leepali zokutshintsha kwepali enye libhekiselele kwinani lemigca eqhawukayo isitshixo (ivale) unikezelo lwamandla.Ngokomzekelo, umgca wesigaba esisodwa se-220V, umgca wesigaba esisodwa ungasetyenziselwa ukuphula umgca wesigaba (ucingo oluphilayo, umgca we-L), kunye nomgca ongathathi hlangothi (umgca we-N) wenza Emva kokutshintsha, ukutshintshwa kwinqanaba le-2. ingasetyenziselwa ukuvula nokukhupha umgca wesigaba kunye nomgca we-N ngexesha elinye.Ngokuhambelana ne-3-isigaba se-380v, kukho i-3 okanye i-4-level yosetyenziso lweemeko zokusetyenziswa ngokulandelelana.Ukutshintshela apha ngokubanzi kubhekiselele kwi-breaker circuit.
Ukusetyenziswa kwazo ngokwahlukileyo:
1. Ukutshintsha ipali kabini
Iswitshi yolawulo olumbini lutshintsho olunabafowunelwa ababini (oko kukuthi, iperi) yesiqhelo evulekileyo neqhele ukuvalwa ngaxeshanye.Ngokuqhelekileyo izitshixo ezimbini zolawulo-mbini zisetyenziselwa ukulawula isibane okanye ezinye izixhobo zombane, kwaye kunokubakho iiswitshi ezimbini zokulawula izibane kunye nezinye izixhobo zombane.
Umzekelo, vula iswitshi xa usiya ezantsi, kwaye ucime iswitshi xa usiya phezulu.Ukuba usebenzisa iswitshi yemveli, kuya kufuneka ubaleke ezantsi ukucima isibane ukuba ufuna ukucima isibane.Ukusebenzisa isitshixo solawulo-mbini kunokunqanda le ngxaki.Umtshini wolawulo olubini lukwasetyenziselwa ukulawula izibane ezifuna ukutshiswa ngokunyanzeliswa kwisekethe yokukhanyisa engxamisekileyo.Iziphelo ezimbini zokutshintsha kokulawula kabini zixhunyiwe kumbane ombini, kwaye enye isiphelo siqhagamshelwe kwizibane, oko kukuthi, iswitshi enye ilawula isibane esinye.
2. Ukutshintsha ipali enye
Ulawulo olulodwa lutshintsho oluqhelekileyo, iswitshi enye ilawula ukukhanya okunye, kwaye ulawulo olubini lusetyenziswa apho iiswitshi ezimbini zilawula ukukhanya okunye.
