Kusarudzwa kwevanobatika kuchaitwa zvinoenderana nezvinodiwa zvemidziyo inodzorwa. Kunze kwekunge yakayerwa kushanda voltage ichave yakafanana neyakayerwa voltage yemidziyo inochajirwa, chiyero chekuremerwa, chikamu chekushandisa, mafambisirwo ekushanda, hupenyu hwekushanda, yekuisa maitiro, saizi uye hupfumi hwemidziyo inochajiswa ndiyo hwaro hwekusarudzwa.
Contactors anoshandiswa munhevedzano uye parallel
Kune michina yakawanda yemagetsi iyo inotakura imwe-chikamu uye, naizvozvo, matanda akawanda e-multipole contactors anogona kushandiswa mune parallel.Sekupikisa vira, welding transformer, etc.Kana yakashandiswa pamwe chete, diki diki contactor inogona kusarudzwa. Nekudaro, zvinofanirwa kucherechedzwa kuti iyo yakabvumiranwa kupisa ikozvino kweiyo contactor mushure mekuenderana haina kuenzana nenhamba yemapango ari parallel.Izvi imhaka yekuti kupikisa kukosha kweiyo inoshanda, static contact loop haifaniri kunge yakaenzana zvachose, kuitira kuti ikozvino inoyerera kuburikidza nechakanaka haina kugoverwa zvakaenzana.Saka, ikozvino inogona kungowedzera kusvika 1.8 nguva dzakafanana, uye mushure mokunge matanda matatu ari kufanana, ikozvino inogona kungova chete. yakawedzera kusvika ku2 kusvika ku2.4 nguva.
Mukuwedzera, zvinofanirwa kutaurwa kuti nekuda kwekuti matanda ekusangana haagone kubatanidzwa uye kubviswa panguva imwechete mushure mekufanana, iyo yakabatana uye yekuparadzanisa kugona haigone kuvandudzwa.
Dzimwe nguva, matanda akawanda econtactor anogona kushandiswa munhevedzano, nekuda kwekuwedzera kwekusangana kwekupwanya kunogona kupatsanura arc muzvikamu zvakawanda, kuvandudza kugona kwekudzima kwearc, uye kukurumidza kudzima kwearc. Naizvozvo, mapango akawanda anogona kuwedzerwa mukati. series, asi haigoni kudarika rated insulation voltage of the contactor.The yakabvumirana kudziyisa ikozvino uye rated kushanda ikozvino of the contactor munhevedzano haizoshanduki.
Mhedzisiro yemagetsi ekupa frequency
Nokuda kwedunhu guru, kuchinja kwehuwandu kunobata maitiro eganda, uye ganda rinowedzera pahuwandu. Pamusoro pezvigadzirwa zvakawanda, 50 uye 60 Hz ine simba guru pakukwira kwekushisa kweiyo conductive circuit.Zvisinei, nokuda kwekukwezva coil, kutarisisa kunofanira kubhadharwa. Iyo 50 H dhizaini inodzikisa iyo magineti flux yemagetsi mutsara pa60 Hz, uye kuyamwa kuchaderedzwa. Pasinei nokuti kushandiswa kunoenderana nemuganhu wekugadzirwa kwayo.Muzhinji, mushandisi anonyanya kuishandisa maererano nekugadzirisa kwayo kukosha uye kurongeka maererano nehuwandu hwemagetsi ekushanda.
Migumisiro yehuwandu hwekushanda
Huwandu hweawa yeawa yekushanda yevanobatika ine simba guru pakupisa kurasikirwa kwevanobatika, saka kutarisisa kunofanirwa kubhadharwa kune kusarudzwa. Iyo inoshanda yekushanda frequency inopiwa mune tekinoroji parameters yevanobatika.Kana iyo chaiyo yekushanda frequency yemagetsi emidziyo yakakwirira kupfuura iyo yakapihwa kukosha, iyo contactor inofanira kuderedza kuderedzwa kukosha.
Kusarudzwa kweAC macontactor ekudzora emagetsi ekupisa midziyo
Rudzi urwu rwemidziyo ine choto chekudzivirira, tembiricha inodzora hita, nezvimwewo. Ikozvino kushanduka kwemhando yemutoro wakadaro idiki kwazvo, iyo ndeye AC-1 zvinoenderana nechikamu chekushandisa. The contactor anogona kudzora mutoro akadaro nyore, uye oparesheni hakusi kakawanda.Naizvozvo, pakusarudza contactor, chero yakabvumiranwa kudziyisa ikozvino Ith of contactor yakaenzana kana kupfuura 1.2 nguva kushanda ikozvino yemagetsi thermal midziyo. Muenzaniso 1: A contactor inosarudzwa kudzora 380V uye 15KW matatu-phase Y-yakaita Y-yakaita HW.Solution: tanga kuverenga yakarongwa kushanda ikozvino Ie yechikamu chimwe nechimwe.The Ith = 1.2Ie = 1.2 × 22.7 = 27.2A saka anosarudza chero mhando contactor pamwe akabvumira kupisa ikozvino Ith≥27.2A.Somuenzaniso: CJ20-25, CJX2-18, CJX1-22, CJX5-22 uye mamwe mhando.
Dzora kusarudzwa kwevanobatika kwemagetsi ekuvhenekera
Kune marudzi akawanda emagetsi ekuvhenekesa, marudzi akasiyana-siyana emagetsi ekuvhenekera, kutanga ikozvino uye nguva yekutanga yakasiyanawo.Mitoro yakadaro inoshandisa chikamu AC-5a kana AC-5b.Kana nguva yekutanga ipfupi kwazvo, iyo yakabvumirana kupisa ikozvino Ith yakaenzana. kusvika ku1.1 nguva dzekushanda ikozvino kwemidziyo yekuvhenekera Ie. Kana nguva yekutanga ikareba zvishoma uye chiyero chechiyero chakaderera, iyo inobvumira kupisa ikozvino yakakura kudarika kushanda ikozvino kwemagetsi ekuvhenekera, tarisa Tafura 1. Tafura 1 Kusarudzwa kwenheyo ye contactor yekudzora magetsi emagetsi No. magetsi ekupa COS kutanga nguva min contactor kusarudza musimboti
