Abafowunelwa bahlulwe ngokwee-AC zoqhagamshelwano (i-voltage AC) kunye ne-DC contactors (i-voltage DC), ezisetyenziselwa amandla, ukuhanjiswa kunye nezihlandlo zombane. okwangoku ukuvelisa indawo yamagnetic kwaye uvale abafowunelwa ukulawula umthwalo.
Kwi-electrology, kuba inokunqumla ngokukhawuleza i-ac kunye ne-DC eyona loop kwaye inokuvula rhoqo kunye nolawulo lwangoku oluphezulu (ukuya kuthi ga kwi-800A) isekethe, isoloko isetyenziswa kwimotor 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.
Iindlela zokontraka ziyasebenza
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, uqhagamshelwano oluhlala luvulekile lunqanyuliwe, kwaye uqhagamshelwano oluhlala luvaliwe luyavalwa. Abafowunelwa beDC basebenza ngendlela efana neyokutshintsha ubushushu.Indlela yocingo yokuqhagamshela iAC
1,3,5 Kubonelelo lombane lwezigaba ezithathu, (inxalenye yesekethe engundoqo)
2,4, kunye no-6 Qhagamshela kwimotor yesigaba esithathu
I-A1, i-A2 yi-coil ye-contactor, edibeneyo kwisiphaluka solawulo, kunye ne-motor elawula isiphaluka (enkulu) ngokulawula i-coil ye-contactor (A1, A2).
I-13,14 imele uqhagamshelwano oluncedisayo lwe-contactor, kwaye i-NO ivuliwe ngokuqhelekileyo, ithetha ukuba i-13,14 inqanyuliwe, kwaye i-13,14 ivaliwe emva kombane. , ukufezekisa injongo yokusebenza ngokuqhubekayo.
Okokuqala, abafowunelwa bamandla abathathu abaphambili L1, L2, L3 ye-contactor, kwaye emva koko iingcingo ezintathu ezivela kwi-T1, T2, T3 ye-contactor, ngasentla yisekethe eyintloko.
Ulawulo lwesiphaluka: ukusuka kwi-L1 ukuya kwiqhosha lokumisa uxhumano lwentambo (iqhosha lokumisa lihlala livaliwe, iqhosha lokuqala lihlala livulekile, oku kufuneka ukwazi!) esinye isiphelo sesinye isiphelo soqhagamshelwano oluncedisayo (le nxalenye i-self-lock), i-coil A1 kunye ne-coil A2 idibanisa i-L2 okanye i-L3.
Okokuqala, siqala ukuqonda ulwazi oluninzi olusisiseko lweSchneider AC contactor inezinto ezimbini ezisisiseko, uqhagamshelwano oluphambili kunye nentloko encedisayo, uqhagamshelwano oluphambili lusetyenziselwa ukudibanisa nezixhobo zombane okanye ukudibanisa kwisekethe eyintloko, uqhagamshelwano oluncedisayo ludityaniswe kulawulo. isekethe, esetyenziselwa ukulawula isekethe ephambili.
Uqhagamshelwano oluphambili ludityaniswe ngokubanzi kwisekethe ephambili, njengoko kumyalelo xa kungekho mfuneko zikhethekileyo, uqhagamshelwano oluncedisayo ludityaniswe kwisiphaluka solawulo, ngokuqhelekileyo ukukhetha ukuba kaninzi uvula indawo yoqhagamshelwano okanye kaninzi uvalwe indawo yoqhagamshelwano.Olu khetho lusekelwe kwiimfuno zelophu yolawulo.Ngokuqhelekileyo, ukuba i-AC contactor idla ngokuvula kwaye abafowunelwa abavaliweyo akwanelanga, thatha i-Schneider njengomzekelo, umbutho unokongezwa phezulu.Ufana noonxibelelwano oluqhelekileyo oluvulekileyo noluvaliweyo luyafumaneka ukuze lusetyenziswe.
Isigwebo se-AC contactor sihlala sivulekile kwaye sihlala sivala uluhlu lokutshintsha lunokusebenzisa itafile yendalo yonke, xa umlinganiselo wetafile jikelele usandi ukungqina uqhagamshelwano oluvaliweyo oluqhubekayo, xa itafile yendalo yonke ayithethi isandi idla ngokuvula uqhagamshelwano, cofa i-axiliary. Iqhosha elihlala livuliwe lizakukhala, livalwa rhoqo alizukukhala.
