AC contactor mbali yaikulu

Choyamba, makhalidwe atatu akuluakulu a AC contactor:
1. AC contactor koyilo.Makoko nthawi zambiri amadziwika ndi A1 ndi A2, ndipo amatha kugawidwa kukhala ma AC contactors ndi DC contactors.Nthawi zambiri timagwiritsa ntchito ma AC contactors, omwe 220 / 380V ndi omwe amagwiritsidwa ntchito kwambiri:
2. AC Contactor Main kukhudzana.L1-L2-L3 yolumikizidwa ndi chingwe chamagetsi cha magawo atatu, ndipo T1 T2-T3 imalumikizidwa ndi chingwe chamagetsi, ndipo ingagwiritsidwe ntchito kulumikiza chingwe chonyamula.Zolumikizana zazikulu za AC contactor nthawi zambiri zimakhala zotseguka, makamaka zogwirizana ndi dera lalikulu, kulamulira chiyambi ndi kuyimitsidwa kwa galimoto ndi zipangizo zina!
3. Othandizira othandizira a AC contactor.Othandizira othandizira amatha kugawidwa kukhala malo otseguka osalekeza NO ndipo nthawi zambiri amatsekedwa NC.
3-1 Nthawi zambiri lotseguka mfundo NO, nthawi zambiri lotseguka mfundo NO zimagwiritsa ntchito contactor kudziletsa kudziletsa kudziletsa ndi kutengerapo chizindikiro ntchito ntchito, monga: AC contactor nthawi zambiri lotseguka mfundo NO kuti wofiira chizindikiro kuwala angagwiritsidwe ntchito monga galimoto galimoto. chizindikiro kuwala, pamene AC contactor mphamvu, nthawi zambiri lotseguka mfundo NO kutsekedwa, kuyatsa chizindikiro kuwala, kufalitsa galimoto kapena dera ntchito chizindikiro.
3-2.Normal-chatsekedwa mfundo NC wa AC contactor.Nthawi zambiri, NC imagwiritsidwa ntchito kwambiri polumikizirana madera ndi kutumiza ma sign.
Mwachitsanzo, galimoto zabwino ndi n'zosiyana ulamuliro dera amagwiritsa ntchito interlocking wa contactor zonse chatsekedwa mfundo NC.
Mwachitsanzo, AC contactor zonse kutseka mfundo NC chikugwirizana ndi wobiriwira chizindikiro kuwala, amene angagwiritsidwe ntchito ngati chizindikiro amasiya dera kapena galimoto.Pamene cholumikizira cha AC chimayatsidwa, malo otseka nthawi zonse NC amachotsedwa, chowunikira choyimitsa chazimitsidwa, kuwala kofananirako kumayatsidwa, ndipo dera limayendera.
Chachiwiri, ine ndikumvetsa makhalidwe atatu kunja kwa AC contactor, ndiyeno tione mosavuta mkati mwa AC contactor:
Choyamba, zigawo zikuluzikulu za AC contactor: koyilo, chitsulo pakati, bwererani kasupe, dongosolo kukhudzana ndi zida ndi zigawo zina zimapanga.
1. Mwachidule kumvetsa zida za AC contactor.Chombocho chimagwirizanitsa njira yolumikizirana, pamene zida zikuyenda mmwamba ndi pansi, malo okhudzana nawo adzasintha molingana, monga: nthawi zambiri malo otseguka NO otsekedwa, nthawi zambiri amatsekedwa NC yotsekedwa ndi zina zotero, izi ndizo ntchito zoyamba!
2. Zina zofunika zigawo zikuluzikulu: pachimake, koyilo ndi bwererani akasupe!Kumvetsetsa mwachidule za chidziwitsochi ndi:
Umu ndi momwe olumikizirana ndi AC amagwirira ntchito m'chinenero chofikirika kwambiri:
Pamaso pa AC contactor si mphamvu: koyilo sangakhale magetsi, pachimake alibe mphamvu maginito kuyamwa, armature sangasunthe, kasupe elasticity amakhalabe yachibadwa, nthawi ino nthawi zambiri lotseguka Mfundo NO kuzimitsa, nthawi zambiri kutsekedwa mfundo NC ndi pa, ichi ndi chikhalidwe chachibadwa.
AC contactor magetsi: koyilo magetsi, chitsulo pachimake kubala electromagnetic kuyamwa, angathe kugonjetsa bwererani kukhuthala kasupe, kukokera pang'ono anasunthira pansi, nthawi ino kukhudzana dongosolo kusintha: nthawi zambiri lotseguka mfundo NO kutsekedwa, nthawi zambiri kutsekedwa mfundo NC kulumikizidwa, ichi ndi chofunika kwambiri. contactor control, contactor ndi kukhudzana pa-off kusintha kusalunjika kulamulira dera!
Pambuyo pa AC contactor kutaya mphamvu kapena mphamvu kuzimitsa, koyilo sangakhale magetsi, pachimake alibe kuyamwa atomu, nthawi ino bwererani kasupe elasticity amayendetsa zida Bwezerani, armature bounce, nthawi ino armature amayendetsa AC contactor kukhudzana dongosolo kayendedwe, kubwezeretsa ku chikhalidwe choyamba: nthawi zambiri lotseguka mfundo NO kuchotsedwa, nthawi zambiri kutsekedwa mfundo NC kutsekedwa pa.
