Umsebenzi kazibuthe we-latching awukona ukuvala lapho ugesi ungekho, okuwumshini ocindezela inkinobho yokuvala, futhi inkinobho yokuvala kuphela engacindezelwa ngogesi. Isetshenziselwa kakhulu ukuvimbela abasebenzi ukuthi bangathinteki ngephutha isekethe yokuvala ebangelwa izingozi noma inqola yesandla ingekho endaweni yokuvala ingozi. I-interlock circuit yayo ingakha futhi i-interlock kagesi nge-switch disconnector, switch switch.
I-electromagnetic latching isetshenziswa ngokuhambisana nesekethe yangaphandle ukuvimbela ukuvala i-circuit breaker ngephutha (yebo, ingasetshenziswa futhi kuzixhumi noma ekushintsheni kokulayisha). Kumjikelezo wokuvala we-circuit breaker, iphoyinti elisizayo elivulekile lixhunywe ochungechungeni, futhi isifunda sokuvala sizovuleka kuphela lapho amandla evinjiwe. Induku ephezulu ye-electromagnetic latching ifakwe eduze kwe-shaft yokuvala, futhi uma ingamuncwa, induku ephezulu izokhiya indlela yokuvala, ukuze i-circuit breaker ingakwazi ukuvalwa ngesandla. Ngakho-ke, lapho ugesi ungekho, ungavimbela kokubili ukuvala ugesi kanye nesandla.
Uma i-electromagnetic latching ku-circuit breaker (inqola ephathwayo) isebenza noma uma ipulaki yesibili ingakhishwa, kuhlala kukhona okwamanje ngozibuthe kagesi. I-circuit breaker ingavala lapho i-electromagnet ivala. Khipha i-plug-in yesibili, lapho i-electromagnetic ingenawo amandla, insimbi ephakathi nendawo iyawa ukuze kuvinjwe i-breaker circuit ukuthi ivaleke. Umsebenzi uwukuvimbela isiqhephusi sesifunda ukuthi sivale lapho ipulaki yesibili ikhishwa.
Kunezinhlobo ezimbili eziyinhloko zokuvimbela kazibuthe:
1. Ukuvala nokukhiya kazibuthe kagesi kusetshenziswa ukukhiya nokuvala. Kuphela uma i-electromagnetic inamandla, i-breaker yesifunda ingavalwa ngemva kokuba i-electromagnet ivala. Ngokuvamile isetshenziselwa ukuxhuma phakathi kwama-circuit breaker. Isibonelo, ukungeza i-electromagnet enjalo ebambekayo ohlelweni lokuphuka kwebhasi elilodwa lama-breaker circuit amabili angenayo kuzoqinisekisa ukuthi kufakwa isiphambano sesifunda esisodwa kuphela.
2. I-electromagnetic latching yenqola ye-circuit breaker iwukuvikela ukuthi i-circuit breaker ingagqekezelwa noma iphume ngephutha. Esimeni sokuhlola, kuphela lapho i-electromagnetic latching ivuliwe, khona-ke i-breaker yesifunda ingakhishwa.
