Umsebenzi we-electromagnetic latching awuyi kuvala xa kungekho mbane, eyona ndlela idibanisa iqhosha lokuvala, kwaye iqhosha lokuvala kuphela linokucinezelwa ngombane. Ikakhulu isetyenziselwa ukuthintela abasebenzi ukuba bangachukumisi ngempazamo umjikelezo wokuvala obangelwe ziingozi okanye inqwelo yesandla ayikho endaweni yokuvala ingozi. Isiphaluka sayo se-interlock sinokwenza i-interlock yombane kunye ne-disconnector switch, i-load switch.
I-electromagnetic latching isetyenziswe ngokubambisana nesiphaluka sangaphandle ukuthintela ukuvala i-breaker circuit ngempazamo (ewe, inokusetyenziswa kwakhona kwii-disconnectors okanye i-switch switches). Kwisekethe yokuvala i-circuit breaker, indawo yokuncedisa evulekileyo ngokuqhelekileyo idibaniswe kwichungechunge, kwaye isiphaluka sokuvala siya kuvuleka kuphela xa umbane uvaliwe. Intonga ephezulu ye-electromagnetic latching ifakwe ecaleni kwe-shaft yokuvala, kwaye xa ingaxutywanga, intonga ephezulu iya kuvala indlela yokuvala, ukwenzela ukuba i-breaker circuit ingakwazi ukuvalwa ngesandla. Ngoko ke, xa kungekho mbane, unokuthintela zombini ukuvalwa kombane kunye nesandla.
Xa i-electromagnetic latching kwi-breaker circuit (inqwelo yesandla) isebenza okanye xa iplagi yesibini ingakhutshwa, kusoloko kukho okwangoku nge-electromagnetic. I-breaker circuit inokuvala xa i-electromagnet ivala. Khupha i-plug-in yesibini, xa i-electromagnetic ingenawo amandla, intsimbi ephakathi iyawa ukukhusela i-breaker circuit ukuba ivale. Umsebenzi kukuthintela i-breaker circuit ekuvaleni xa i-plug-in yesibini ikhutshwe.
Kukho iindidi ezimbini eziphambili zokuthintela i-electromagnets:
1. Ukuvala kunye nokutshixa i-electromagnetic isetyenziselwa ukutshixa nokuvala. Kuphela xa i-electromagnetic inamandla, i-breaker circuit ingavalwa emva kokuba i-electromagnet ivaliwe. Idla ngokusetyenziselwa ukudityaniswa phakathi kwezaphuli zesekethe. Ngokomzekelo, ukongeza i-electromagnetic latching kwi-single-bus breaking system ye-breaker circuit ezimbini ezingenayo kuya kuqinisekisa ukuba i-breaker circuit enye kuphela esebenzayo.
2. I-latching electromagnet ye-handcart ye-circuit breaker kukuthintela i-breaker circuit ukuba ihlaselwe ngaphakathi okanye ngaphandle ngempazamo. Kwimeko yokuvavanya, kuphela xa i-electromagnetic latching inikwe amandla, ngoko i-breaker circuit inokukhutshwa.
