Abafowunelwa bahlulwe kwii-AC zoqhagamshelwano (i-voltage AC) kunye ne-DC contactors (i-voltage DC), ezisetyenziselwa amandla, ukuhanjiswa kunye nezihlandlo zombane.Ngokwengqiqo ebanzi, i-contactor ibhekisela kwizixhobo zombane zemizi-mveliso ezisebenzisa i-coil current ukuvelisa intsimi yamagnetic kunye vala abafowunelwa ukulawula umthwalo.
Kwi-electroscience, kuba inokunqumla ngokukhawuleza i-ac kunye ne-DC main loop kwaye inokuvula rhoqo kunye nolawulo oluphezulu lwangoku (ukuya kuthi ga kwi-800A) isekethe, isoloko isetyenziswa kwi-motor njengento yokulawula inokusetyenziswa njengesixhobo sokulawula isixhobo sokwenza isifudumezi. kunye nomthwalo ohlukeneyo wamandla, i-contactor ayinakuvula kuphela kwaye inqumle isiphaluka, kodwa iphinde ibe nefuthe eliphantsi lokukhutshwa kombane. .
Kwimizi-mveliso yombane, kukho iimodeli ezininzi zonxibelelwano, kwaye ukusebenza kwangoku kuyahluka kwi-5A-1000A, kwaye ukusetyenziswa kwayo kubanzi.
Umgaqo wekontraki uyasebenza
Umgaqo osebenzayo we-contactor yile: xa i-coil ye-contactor inamandla, i-coil yangoku iya kuvelisa i-magnetic field, i-magnetic field yenza i-static core ivelise i-electromagnetic suction ukutsala i-core, kwaye iqhube i-AC contactor point action, ihlala ivala uqhagamshelwano. Xa i-coil ivaliwe, i-electromagnetic suction iyanyamalala, kwaye i-armature ikhutshwe phantsi kwesenzo sokukhululwa kwentwasahlobo, okwenza ukuba umnxibelelwano abuyele, umfowunelwa osoloko evuliwe uyanqanyulwa, kwaye uqhagamshelwano oluhlala luvaliwe luyavalwa.Abafowunelwa beDC basebenza ngendlela ethile efana nokutshintsha kobushushu.Indlela yokuqhagamshela i-AC yoqhagamshelwano
