Detection method of contactor 1. Nzira yekuona ye AC contactor
Iyo AC contactor iri padanho repamusoro reiyo thermal protection relay yekubatanidza kana kudzima tambo yemagetsi yemudziyo.Kukurukurirana kukuru kweiyo contactor yakabatana nemagetsi emagetsi, uye coil yakabatanidzwa kune control switch.Kana iyo contactor yakakuvadzwa, kukosha kwekupikisa kwekubatana uye coil ichaonekwa.Iyo dhizaini inoratidza yakajairika mota control wiring diagraph
Asati aonekwa, materminals of the contactor anozivikanwa maererano nekuzivikanwa pane contactor dzimba.Zvichienderana nekuzivikanwa, zviteshi 1 ne2 zviteshi zvechikamu mutsara L1, zviteshi 3 ne4 zviteshi zvechikamu mutsara wechigumi nembiri, zviteshi 5 ne6 zviteshi zvechikamu mutsara L3, zviteshi 13 ne14 ndezvokubatsira, uye A1 neA2. macoil terminals ekuzivikanwa kwepini.
Kuti uite kuti mhinduro yegadziriso ive yakarurama, iyo AC contactor inogona kubviswa kubva kumutsara wekutonga, uyezve mushure mekuunganidzwa kweiyo wiring terminal inogona kutongwa zvinoenderana nekuzivikanwa, uye iyo multimeter inogona kugadziridzwa ku "100" nguva yekupikisa. kuona kukosha kwekupokana kweiyo contactor coil.Isa zvinyoreso zvitsvuku uye zvitema zvewachi pane iyo wiring terminal yakabatana necoil, uye pasi pemamiriro akajairwa, kuyerwa kwekupikisa kukosha ndeye 1,400 Ω.Kana kushorwa kusingagumi kana kushorwa kuri 0, iyo contactor yakakuvadzwa.Nhamba yacho inoratidza kukosha kwekupokana kweiyo coil yekuona
Zvinoenderana nekuzivikanwa kweiyo contactor, zvese zviri zviviri zvinonyanya kutaurwa uye ebetsero yeanobata anowanzo kuvhurika mazita.Iwo matsvuku uye matema mapeni ewachi anoiswa pane iyo wiring terminal yechero nzvimbo yekusangana, uye iyo yakayerwa kuramba kukosha haina magumo.Iyo nhamba inoratidza kukosha kwekupokana kweavo vakaonekwa vanobatika.
Apo bhari rezasi rinodzvinyirirwa nemaoko, kushamwaridzana kuchavhara, mapeni etafura matsvuku uye madema haazofambi, uye kupikisa kuyerwa kunova 0. Mufananidzo unoratidza kukosha kwekupikisa kwekusangana nekutsikirira bhari rezasi.
