Ma contactor amagawidwa m'ma AC contactors (voltage AC) ndi DC contactors (voltage DC), omwe amagwiritsidwa ntchito pamagetsi, kugawa ndi nthawi zamagetsi. panopa kupanga mphamvu ya maginito ndi kutseka zolumikizirana kuti ziwongolere katunduyo.
Mu electrology, chifukwa amatha kudula mwachangu ma AC ndi DC main loop ndipo amatha kuyatsa pafupipafupi komanso kuwongolera kwakanthawi kochepa (mpaka 800A) dera, lomwe nthawi zambiri limagwiritsidwa ntchito mugalimoto ngati chinthu chowongolera, lingagwiritsidwenso ntchito ngati jenereta yowongolera zida zopangira magetsi. ndi katundu osiyanasiyana mphamvu, contactor osati kuyatsa ndi kudula dera, komanso otsika voteji kumasulidwa chitetezo effect.Connactor ulamuliro mphamvu ndi lalikulu, oyenera ntchito pafupipafupi ndi kulamulira kutali, ndi chimodzi mwa zigawo zofunika mu dongosolo basi kulamulira. .
Mu magetsi mafakitale, pali zitsanzo zambiri za contactors, ndi ntchito panopa zimasiyanasiyana 5A-1000A, ndipo ntchito yake ndi ponseponse.
Kontrakitala imagwira ntchito
Mfundo ntchito ya contactor ndi: pamene koyilo contactor ndi mphamvu, koyilo panopa adzabala maginito, ndi maginito amapanga malo amodzi pachimake kubala maginito suction kukopa pachimake, ndi kuyendetsa AC contactor mfundo kanthu, nthawi zambiri kutseka kukhudzana. kulumikizidwa, nthawi zambiri kumatsegula kulumikizidwa kotsekedwa, ziwirizo zimalumikizana. Pamene koyiloyo yazimitsidwa, kuyamwa kwamagetsi kumatha, ndipo zida zimatulutsidwa pansi pakuchitapo kanthu kwa kasupe wotulutsa, kupangitsa kuti kulumikizana kuchira, kulumikizidwa kotseguka kumachotsedwa, ndipo kukhudzana nthawi zambiri kutsekedwa kumatsekedwa.DC ma contacts amagwira ntchito mofananamo ndi kusintha kwa kutentha.AC contactor wiring njira
1,3,5 Pamagetsi a magawo atatu, (gawo lalikulu)
2, 4, ndi 6 Lumikizani ku mota yamagawo atatu
A1, A2 ndi ma coils a contactor, olumikizidwa ku dera ulamuliro, ndi galimoto kulamulira dera (lalikulu) ndi kulamulira koyilo wa contactor (A1, A2).
13,14 Imayimira kukhudzana kothandizira kwa contactor, ndipo NO nthawi zambiri imatsegulidwa, kutanthauza kuti 13,14 imachotsedwa, ndipo 13,14 imatsekedwa pambuyo pa mphamvu. , kukwaniritsa cholinga cha ntchito mosalekeza.
Choyamba, waukulu atatu mphamvu kulankhula L1, L2, L3 wa contactor, ndiyeno mawaya atatu kuchokera T1, T2, T3 wa contactor, pamwamba ndi dera waukulu.
Kuwongolera kuzungulira: kuchokera ku L1 kupita ku batani loyimitsa waya (batani loyimitsa nthawi zambiri limatsekedwa, batani loyambira nthawi zambiri limatseguka, izi ziyenera kudziwa!) mbali ina ya mapeto ena a kukhudzana wothandiza (gawo ili ndi lodzikhoma), koyilo A1 ndi koyilo A2 kulumikiza L2 kapena L3.
Choyamba, ife choyamba kumvetsa mfundo zingapo zofunika za Schneider AC contactor ali zinthu ziwiri zofunika, kukhudzana waukulu ndi mutu wothandizira, kukhudzana waukulu ntchito kukhudzana ndi zida zamagetsi kapena olumikizidwa ku dera lalikulu, kukhudzana wothandiza chikugwirizana ndi ulamuliro. dera, lomwe limagwiritsidwa ntchito kuwongolera dera lalikulu.
Kulumikizana kwakukulu nthawi zambiri kumalumikizidwa ndi dera lalikulu, monga momwe dongosololi lilibe zofunikira zapadera, kukhudzana kothandizira kumalumikizidwa ndi dera lowongolera, makamaka kusankha ngati nthawi zambiri zimatseguka kapena nthawi zambiri zimatsekedwa. pa zofunikira za loop control.Nthawi zambiri, ngati AC contactor nthawi zambiri lotseguka ndi kutsekedwa kulankhula sikokwanira, kutenga Schneider mwachitsanzo, bungwe akhoza kuonjezedwa pamwamba.Similar kuti kawirikawiri lotseguka ndi otsekedwa kulankhula zilipo ntchito.
Chigamulo cha AC contactor nthawi zambiri lotseguka ndipo nthawi zambiri kutseka lophimba osiyanasiyana angagwiritse ntchito tebulo lonse, pamene chilengedwe tebulo muyeso ndi phokoso kutsimikizira zonse chatsekedwa kukhudzana, pamene tebulo chilengedwe si phokoso nthawi zambiri lotseguka kukhudzana, akanikizire wothandiza. batani nthawi zambiri lotseguka lidzalira, nthawi zambiri lotsekedwa sililira.
