Macontactor akakamurwa kuita AC contactors (voltage AC) uye DC contactors (voltage DC), ayo anoshandiswa musimba, kugovera uye nguva dzemagetsi.Mupfungwa yakafara, iyo contactor inoreva maindasitiri emagetsi emagetsi anoshandisa coil kuyerera nepakati. ikozvino kugadzira magnetic field uye kuvhara macontact kudzora mutoro.
Mu electrology, nekuti inogona kukurumidza kutema ac uye DC main loop uye inogona kugara ichibatidza uye yakakwira ikozvino kudzora (kusvika ku800A) dunhu, saka inowanzoshandiswa mumotokari sechinhu chekudzora chinogona kushandiswawo seyekudzora chirimwa midziyo yekupisa jenareta. uye zvakasiyana-siyana simba rekutakura, contactor haigoni kutendeuka uye kugura dunhu chete, asiwo ine yakaderera voltage release protection effect.Connactor control capacity yakakura, yakakodzera kushanda nguva dzose uye kure kure, chimwe chezvinhu zvinokosha mu otomatiki control system. .
Mumagetsi emaindasitiri, kune akawanda mamodheru evanobatika, uye ikozvino kushanda kunosiyana mu5A-1000A, uye kushandiswa kwayo kwakapararira.
Contractor mechanism inoshanda
Nheyo yekushanda yecontactor ndeye: kana coil coil yapihwa simba, iyo coil ikozvino inoburitsa magineti, iyo magineti inoita iyo static musimboti ibudise electromagnetic suction kukwezva musimboti, uye kutyaira iyo AC contactor point action, kazhinji kuvhara iyo yekubata. yakadzimwa, kazhinji inovhura iyo yekubatanidza yakavharwa, maviri ari linkage. Kana iyo coil ikadzimwa, iyo electromagnetic suction inonyangarika, uye armature inoburitswa pasi pechiito chekuburitsa chitubu, ichiita kuti iyo yekubata idzore, iyo inowanzo kuvhurika kusangana inobviswa, uye iyo inowanzovharwa inovharwa yakavharwa.DC macontacts anoshanda neimwe nzira yakada kufanana kune tembiricha switch.AC contactor wiring method
1,3,5 Yemagetsi ezvikamu zvitatu, (chikamu chikuru chedunhu)
2,4, uye 6 Batanidza kune matatu-chikamu mota
A1, A2 ndiwo macoils eiyo contactor, akabatana nekudzora dunhu, uye mota inodzora dunhu (huru) nekudzora coil yecontactor (A1, A2).
13,14 Inomiririra kushamwaridzana kwekubatsira kwekubatanidza, uye NO inowanzozaruka, zvinoreva kuti 13,14 yakabviswa, uye 13,14 yakavharwa mushure memagetsi. , kuzadzisa chinangwa chekuenderera mberi kwekushanda.
Chekutanga, chikuru matatu simba contacts L1, L2, L3 of contactor, uye ipapo waya nhatu kubva T1, T2, T3 of contactor, pamusoro ndiye guru redunhu.
Kudzora dunhu: kubva kuL1 kutungamirira kune waya yekubatanidza bhatani rekumisa (kumira bhatani rinowanzovharwa, bhatani rekutanga rinowanzo kuvhurika, izvi zvinofanirwa kuziva!) Kubva pane yekumisa bhatani kusvika kune imwe mugumo webhatani rekutanga uye iyo contactor yekubatsira kuonana, uye ipapo kubva imwe mugumo weimwe mugumo weanobatsira kuonana (ichi chikamu chakazvivharira), iyo coil A1 uye coil A2 inobatanidza L2 kana L3.
Chekutanga pane zvese, isu tinotanga kunzwisisa akati wandei ruzivo rweSchneider AC contactor ine zvinhu zviviri zvakakosha, iyo huru yekubata uye yekubatsira musoro, iyo huru yekubata inoshandiswa kubata nemidziyo yemagetsi kana yakabatana nedunhu guru, yekubatsira kubata yakabatana nekutonga. dunhu, rinoshandiswa kudzora dunhu guru.
Kukurukurirana kukuru kunowanzobatanidzwa kune guru redunhu, sekurongeka kana pasina zvakakosha zvinodiwa, kushamwaridzana kwekubatsira kunobatanidzwa kune dunhu rekutonga, kazhinji kusarudza kana kazhinji kuzarura nzvimbo yekuonana kana kuti kazhinji yakavharwa. pane zvinodiwa zvekutonga loop.Kazhinji, kana AC contactor inowanzozaruka uye yakavharwa mazita asina kukwana, tora Schneider semuenzaniso, sangano rinogona kuwedzerwa kumusoro.Similar kune inowanzovhura uye yakavharwa mazita anowanikwa kuti ashandiswe.
Kutonga kwe AC contactor kunowanzo kuvhurika uye kazhinji kuvharika switch renji inogona kushandisa tafura yepasirese, kana iyo yepasirese tafura kuyerwa kunonzwika kuratidza iyo inogara yakavharwa kusangana, kana tafura yepasirese isinganzwike kazhinji yakavhurika kubata, dzvanya iyo yekubatsira. bhatani rinowanzovhurika richarira, kazhinji rakavharwa harizorira.
