Basic content ye low voltage AC contactor

Contactor is an otomatiki switching mudziyo unoshandiswa kugara uchibatidza kana kudzima epamusoro-azvino maseketi akadai seAC uye DC main maseketi uye makuru-anokwanisa kutonga maseketi.Panyaya yebasa, mukuwedzera kune otomatiki switching, iyo contactor ine zvakare kure kure mashandiro uye kurasikirwa kwevoltage (kana undervoltage) yekudzivirira basa iro rinoshaikwa nebhunu switch, asi harina kuwandisa uye mapfupi ekudzivirira ekudzivirira mabasa eiyo. low-voltage circuit breaker.
Advantages uye classification of contactors
The contactor ane zvazvakanakira yakakwirira kushanda kakawanda, upenyu hurefu basa, yakavimbika basa, kugadzikana kuita, yakaderera mutengo, uye nyore kugadzirisa.Iyo inonyanya kushandiswa kudzora mota, magetsi ekudziya emagetsi, emagetsi welding michina, capacitor mabhangi, nezvimwewo, uye ndiyo inonyanya kushandiswa mumagetsi drive control circuit Imwe yemhando dzakasiyana-siyana dzekudzora midziyo.
Zvinoenderana nechimiro cheiyo main contact yekubatanidza wedunhu, yakakamurwa kuita: DC contactor uye AC contactor.
Zvinoenderana nemashandiro ekushandisa, yakakamurwa kuita: electromagnetic contactor uye isingaperi magineti contactor.
Chimiro uye musimboti wekushanda we low voltage AC contactor
Chimiro: AC contactor inosanganisira electromagnetic michina (coil, iron core uye armature), main yekubata uye arc yekudzima system, yekubatsira kubata uye chitubu.Iwo main contacts akakamurwa kuita bridge contacts and finger contacts zvichienderana nekugona kwavo.AC macontactor ane ikozvino inodarika 20A akashongedzerwa nearc yekudzima zvivharo, uye mamwe anewo maplateti egidhi kana magineti anofuridza arc midziyo yekudzima;Mapoinzi ebetsero Mapoinzi akakamurwa kuita anowanzo kuvhurika (achifamba padyo) mabikirwo uye anowanzo kuvharika (anofamba akavhurika) macontacts, ese ari mabhiriji-mhando mbiri-kupwanya zvimiro.Iyo yekubatsira yekubatanidza ine diki diki uye inonyanya kushandiswa kupindirana mukudzora dunhu, uye hapana arc yekudzima mudziyo, saka haigone kushandiswa kushandura dunhu guru.Chimiro chinoratidzwa mumufananidzo uri pasi apa:

Nheyo: Mushure mekunge coil yemagetsi emagetsi yapihwa simba, magineti flux inogadzirwa musimbi musimboti, uye electromagnetic kukwezva kunogadzirwa pane armature mweya gap, izvo zvinoita kuti armature ivhare.Iyo huru yekusangana yakavharwa zvakare pasi pedhiraivha ye armature, saka dunhu rakabatana.Panguva imwecheteyo, iyo armature inotyairawo madhiri ekubatsira kuvhara anowanzo kuvhurika mabikirwo uye kuvhura anowanzo kuvharwa mabiko.Kana iyo coil yadzikiswa kana kuti voltage yakadzikiswa zvakanyanya, simba rekukweva rinonyangarika kana kupera simba, iyo armature inovhura pasi pechiito chekuburitsa chitubu, uye iwo makuru uye ebetsero vanobatana vanodzokera kune yavo yekutanga.Zviratidzo zvechikamu chimwe nechimwe che AC contactor inoratidzwa mumufananidzo uri pasi apa:

Models uye tekinoroji zviratidzo zveyakaderera-voltage AC contactors
1. Muenzaniso wepasi-voltage AC contactor
Iwo anowanzo shandiswa AC contactors anogadzirwa munyika yangu CJ0, CJ1, CJ10, CJ12, CJ20 uye zvimwe zvakatevedzana zvezvigadzirwa.MuCJ10 uye CJ12 nhevedzano yezvigadzirwa, zvese zvakakanganiswa zvikamu zvinotora mudziyo webuffer, uyo unoderedza zvine mutsindo kureba kwekusangana uye sitiroko.Iyo yekufambisa sisitimu ine dhizaini inonzwisisika, compact chimiro, uye dhizaini yekubatanidza isina screws, iri nyore kugadzirisa.CJ30 inogona kushandiswa kubatanidza kure uye kupaza maseketi, uye inokodzera kugara uchitanga nekudzora AC mota.

2. Technical zviratidzo zvepasi-voltage AC contactors
⑴Rated voltage: inoreva iyo yakayerwa voltage pane iyo huru yekubata.Anowanzo shandiswa mamakisi ndeaya: 220V, 380 V, uye 500 V.
⑵ Yakatemerwa ikozvino: inoreva iyo yakayerwa ikozvino yeakanyanya kuonana.Anowanzo shandiswa mamakisi ndeaya: 5A, 10A, 20A, 40A, 60A, 100A, 150A, 250A, 400A, 600A.
⑶Magiredhi anowanzo shandiswa eiyo yakayerwa voltage yecoil ndeiyi: 36V, 127V, 220V, 380V.
⑷ Yakayerwa kushanda frequency: inoreva huwandu hwekubatanidza paawa.
Kusarudzwa musimboti we low voltage AC contactor
1. Sarudza rudzi rwe contactor maererano nerudzi rwemutoro ikozvino munharaunda;
2. Iyo yakatemerwa voltage yecontactor inofanira kuva yakakura kudarika kana yakaenzana neyakatemerwa voltage yemutoro wedunhu;
3. Mhepo yakayerwa yekoiri inokwezva inofanirwa kuenderana neiyo rated voltage yeyakabatana control circuit;
4. Ikozvino yakarongerwa inofanira kuva yakakura kudarika kana kuenzana neyakarongwa ikozvino yedunhu guru rinodzorwa.
