Makhalidwe atatu akuluakulu a AC contactor

Choyamba, makhalidwe atatu akuluakulu a AC contactor:

1. The AC contactor coil.Cils zambiri kuzindikiridwa ndi A1 ndi A2 ndipo akhoza kungowagawa mu AC contactors ndi DC contactors.Nthawi zambiri timagwiritsa ntchito ma AC contactors, omwe 220 / 380V ndi omwe amagwiritsidwa ntchito kwambiri:

2. Main kukhudzana mfundo ya AC contactor.L1-L2-L3 chikugwirizana ndi magawo atatu gawo mphamvu polowera mzere, ndi T1 T2-T3 chikugwirizana ndi kutulutsa mphamvu mzere, ndipo angagwiritsidwe ntchito kulumikiza katundu mzere. kukhudzana chachikulu cha AC contactor nthawi zambiri lotseguka kulankhula, makamaka olumikizidwa kwa dera lalikulu, kulamulira chiyambi ndi kuyimitsa galimoto ndi zida zina!

3. Othandizira othandizira a AC contactor.The ojambula wothandizira akhoza kugawidwa mu nthawi zonse lotseguka mfundo NO ndipo kawirikawiri chatsekedwa mfundo NC.

3-1 Nthawi zambiri lotseguka mfundo NO, nthawi zambiri lotseguka mfundo NO makamaka ntchito contactor kudziletsa kudziletsa kudziletsa ndi kutengerapo chizindikiro ntchito ntchito, monga: AC contactor nthawi zambiri lotseguka mfundo NO kuti wofiira chizindikiro kuwala akhoza kutumikira monga galimoto ntchito chizindikiro. kuwala, pamene AC contactor ali magetsi, nthawi zambiri lotseguka mfundo NO kutsekedwa, kuyatsa chizindikiro kuwala, kufalitsa galimoto kapena dera ntchito chizindikiro.

3-2, Normal chatsekedwa mfundo NC wa AC contactor.Generally, ndi NC ntchito kwa interlocking ndi kufala chizindikiro.

Mwachitsanzo, galimoto zabwino ndi n'zosiyana ulamuliro dera amagwiritsa ntchito interlocking wa contactor zonse chatsekedwa mfundo NC.

Mwachitsanzo, AC contactor nthawi zonse kutseka mfundo NC chikugwirizana ndi wobiriwira chizindikiro kuwala, amene angakhale ngati chizindikiro amasiya dera kapena galimoto.Pamene cholumikizira cha AC chikugwiritsidwa ntchito, malo otsekera nthawi zonse NC amachotsedwa, kuwala koyimitsa kwazimitsidwa, kuwala kofananirako kumayatsidwa, ndipo dera limayendera.

Chachiwiri, ine ndikumvetsa makhalidwe atatu kunja kwa AC contactor, ndiyeno tione mosavuta mkati mwa AC contactor:

1. Zigawo zazikulu za AC contactor: koyilo, chitsulo pakati, bwererani kasupe, dongosolo kukhudzana ndi zida ndi zigawo zina.

1. Mwachidule kumvetsa armature wa AC contactor.Armature zikugwirizana dongosolo kukhudzana, pamene zida zikuyenda mmwamba ndi pansi, kukhudzana adzasintha mogwirizana, monga: nthawi zambiri lotseguka mfundo NO kutsekedwa, nthawi zambiri kutsekedwa mfundo NC kuchotsedwa ndi zina zotero, izi. ndiye ntchito yoyambira!

2. Zida zina zofunika: core, coil, and reset springs!Kumvetsetsa mwachidule kwa nkhaniyi ndi:

Umu ndi momwe olumikizirana ndi AC amagwirira ntchito m'chinenero chofikirika kwambiri:

Pamaso pa AC contactor si magetsi: koyilo sangakhale magetsi, pachimake alibe maginito maginito suction, armature sangasunthe, kasupe elasticity amakhalabe yachibadwa, nthawi ino nthawi zambiri lotseguka mfundo NO kuzimitsa, nthawi zambiri chatsekedwa mfundo NC ali pa, ichi ndi chikhalidwe chachibadwa.

AC contactor magetsi: koyilo magetsi, chitsulo pachimake electromagnetic kuyamwa, angathe kugonjetsa bwererani elasticity kasupe, kukoka pang'ono kusuntha pansi, nthawi ino, kukhudzana dongosolo kusintha: nthawi zambiri lotseguka mfundo NO chatsekedwa, nthawi zambiri chatsekedwa mfundo NC kusagwirizana, ichi ndicho kwambiri Basic contactor control, contactor ndi kusintha kukhudzana kuti mosalunjika kulamulira dera!

Pambuyo pa AC contactor kutaya mphamvu kapena mphamvu kuzimitsa, koyilo sidzakhala magetsi, pachimake alibe maginito suction, pa nthawi ino, elasticity wa bwererani kasupe amayendetsa zida Bwezerani, zida bounce, pa nthawi ino, zida abulusa. kukhudzana dongosolo la AC contactor kusuntha, kubwezeretsa kwa boma koyamba: nthawi zambiri lotseguka mfundo NO kuchotsedwa, nthawi zambiri chatsekedwa mfundo NC kutsekedwa pa.
