Basic zili otsika voteji AC contactor

Contactor ndi chipangizo chosinthira chodziwikiratu chomwe chimagwiritsidwa ntchito nthawi zambiri kuyatsa kapena kuzimitsa mabwalo apamwamba kwambiri monga ma AC ndi DC mabwalo akulu ndi mabwalo akulu akulu.Pankhani ya ntchito, kuwonjezera pa kusinthana kwadzidzidzi, cholumikizira chimakhalanso ndi ntchito yakutali komanso kutayika kwa voteji (kapena undervoltage) chitetezo chomwe chimasowa chosinthira chamanja, koma sichikhala ndi zochulukira komanso ntchito zazifupi zoteteza dera. low-voltage circuit breaker.
Ubwino ndi gulu la contactors
The contactor ali ndi ubwino pafupipafupi ntchito mkulu, moyo wautali utumiki, ntchito odalirika, ntchito khola, mtengo wotsika, ndi kukonza zosavuta.Amagwiritsidwa ntchito kwambiri poyang'anira ma motors, zida zamagetsi zamagetsi, makina opangira magetsi, mabanki a capacitor, ndi zina zotero, ndipo amagwiritsidwa ntchito kwambiri pamagetsi oyendetsa magetsi.
Malinga ndi mawonekedwe a dera lalikulu kukhudzana kugwirizana kugwirizana, iwo anawagawa: DC contactor ndi AC contactor.
Malinga ndi limagwirira ntchito, iwo anawagawa: maginito contactor ndi okhazikika maginito contactor.
Kapangidwe ndi mfundo ntchito otsika voteji AC contactor
Kapangidwe: AC cholumikizira chimaphatikizapo ma electromagnetic makina (coil, iron core ndi armature), kulumikizana kwakukulu ndi njira yozimitsa ya arc, kulumikizana kothandizira ndi masika.The kukhudzana waukulu anawagawa mlatho kulankhula ndi kukhudzana chala malinga ndi mphamvu zawo.Zolumikizira za AC zokhala ndi magetsi opitilira 20A zili ndi zovundikira zozimitsira arc, ndipo zina zilinso ndi mbale za gridi kapena zida zozimitsira maginito;Othandizira othandizira Mfundozi zimagawidwa muzolumikizana zomwe zimatseguka (zoyenda moyandikira) ndipo nthawi zambiri zimatsekedwa (zosuntha zotseguka), zonse zomwe zimakhala ngati mlatho wopumira pawiri.Kulumikizana kothandizira kumakhala ndi mphamvu yaying'ono ndipo kumagwiritsidwa ntchito makamaka polumikizana ndi dera lowongolera, ndipo palibe chipangizo chozimitsa cha arc, kotero sichingagwiritsidwe ntchito kusintha dera lalikulu.Kapangidwe kameneka kakuwonetsedwa pachithunzi pansipa:

Mfundo Yofunika: Pambuyo pa coil ya makina a electromagnetic apatsidwa mphamvu, maginito amadzimadzi amapangidwa pakatikati pachitsulo, ndipo kukopa kwa electromagnetic kumapangidwa pamphepete mwa mpweya wa armature, zomwe zimapangitsa kuti chombocho chitseke.Kulumikizana kwakukulu kumatsekedwanso pansi pa galimoto ya armature, kotero kuti dera limagwirizanitsidwa.Nthawi yomweyo, armature imayendetsanso othandizira kuti atseke omwe amatseguka komanso kutsegula omwe amatsekedwa.Pamene koyiloyo imatulutsa mphamvu kapena mphamvu yamagetsi imachepetsedwa kwambiri, mphamvu yoyamwitsa imasowa kapena kufooketsa, zida zimatsegulidwa pansi pa machitidwe a kasupe wotulutsidwa, ndipo ogwirizanitsa akuluakulu ndi othandizira amabwerera ku chikhalidwe chawo choyambirira.Zizindikiro za gawo lililonse la AC contactor akuwonetsedwa chithunzi pansipa:

Zitsanzo ndi zizindikiro luso otsika-voteji AC contactors
1. Chitsanzo cha otsika-voteji AC contactor
Zomwe zimagwiritsidwa ntchito kwambiri ndi ma AC opangidwa m'dziko langa ndi CJ0, CJ1, CJ10, CJ12, CJ20 ndi zina zambiri.Mu mndandanda wazinthu za CJ10 ndi CJ12, mbali zonse zomwe zakhudzidwa zimatengera chipangizo cha buffer, chomwe chimachepetsa mtunda wolumikizana ndi sitiroko.Dongosolo loyenda lili ndi masanjidwe oyenera, mawonekedwe ophatikizika, ndi kulumikizana kopanda zomangira, komwe kuli koyenera kukonza.CJ30 itha kugwiritsidwa ntchito polumikizira kutali komanso kuswa mabwalo, ndipo ndiyoyenera kuyambitsa ndikuwongolera ma mota a AC pafupipafupi.

2. zizindikiro luso otsika-voteji AC contactors
⑴Voteji yovotera: imatanthawuza mphamvu yamagetsi yomwe imayikidwa pagulu lalikulu.Magiredi omwe amagwiritsidwa ntchito kwambiri ndi: 220V, 380 V, ndi 500 V.
⑵Zovoteledwa pano: zimatanthawuza kutengera komwe mumalumikizana wamkulu.Maphunziro omwe amagwiritsidwa ntchito kwambiri ndi awa: 5A, 10A, 20A, 40A, 60A, 100A, 150A, 250A, 400A, 600A.
⑶Magiredi omwe amagwiritsidwa ntchito kwambiri pamagetsi ovotera a koyilo ndi: 36V, 127V, 220V, 380V.
⑷ Mafupipafupi ogwiritsira ntchito: amatanthauza kuchuluka kwa maulumikizidwe pa ola limodzi.
Kusankha mfundo ya otsika voteji AC contactor
1. Sankhani mtundu wa contactor malinga ndi mtundu wa katundu panopa dera;
2. The oveteredwa voteji wa contactor ayenera kukhala wamkulu kuposa kapena wofanana oveteredwa voteji wa dera katundu;
3. Mphamvu yamagetsi ya koyilo yokopa iyenera kukhala yogwirizana ndi mphamvu yamagetsi yamagetsi olumikizidwa;
4. Zomwe zimayikidwa pakali pano ziyenera kukhala zazikulu kuposa kapena zofanana ndi zomwe zikuyendera pa dera lalikulu lolamulidwa.
