AC contactorschikamu chakakosha chemaindasitiri ematunhu.Vanoita semagetsi emagetsi anodzora high voltage uye ikozvino.Kusanganiswa kweAC contactorsuye ekutanga ekudzivirira anobatsira kudzora kunoshanda uye kuchengetedzeka kwemaindasitiri muchina.Mune ino blog, isu tichakurukura maitiro ezvimiro uye mashandisiro ekuchengetedzaAC contactors.
Structural features:
AC contactors vane akasiyana magadzirirwo maficha uye anoshanda masisitimu anovagonesa kunyatso kudzora magetsi maseketi.Iyo yekutanga ine plastiki shell mhando, simbi shell mhando uye mamwe marudzi ekudzivirira, uye nhanho yekudzivirira inogona kusvika IP65.Kesi yekudzivirira inovimbisa kusimba uye mamiriro eiyo AC contactor munzvimbo dzakaomarara dzekushanda.
Iyo yekushandisa dhizaini bhatani rekutanga-kumisa bhatani, uye chinotangisa chinhu chisingadzokerike chinotangisa chine thermal (overload) relay.Shandisa thermal (overload) relays kudzivirira kupisa uye kuve nechokwadi chekuchengetedza muchiitiko chekupfuura.Iyo yekutanga inotora JLE1 AC yekubatanidza ine 35mm yakajairwa gwara renjanji, iyo inogona kusungirirwa zvakananga pane yekutanga base.Iyo yechitatu-phase lead-out hard wire ye thermal (overload) relay inogona kuiswa yakananga muchikamu chechitatu-chikamu chikuru chekubata kweiyo contactor, iyo iri nyore kuungana uye wiring.
Kungwarira pakushandisa:
Iyo huru yehunyanzvi hwekuita zviratidzo uye zvikamu zvemutangi zvinofanirwa kutariswa usati waiswa.Inofanirwa kuve nechokwadi kuti iyo yakatemerwa control circuit voltage Us yekutanga inoenderana neiyo inowanikwa magetsi.Rated control circuit voltage inosanganisira AC 50/60Hz, 24V, 42V, 110V, 220/230V, 240V,
380/400V, 415V, 440V, 480V, 6OOV.Kubatana kwakashata kwemagetsi kunogona kukuvadza chigadzirwa uye kukonzera tsaona dzemagetsi.
Iyo yekushanda frequency ye thermal relay ndeye makumi matatu nguva / awa, hunhu hunofanirwa kuverengerwa kana uchishanda inorema inoenderera muchina.Huwandu hwevatangi vane thermal (overload) relays vane thermal relay inoshanda maitiro ayo anoda kuverengerwa kana uchishandisa chigadzirwa.
mukupedzisa:
Muchidimbu, maAc contactors akakosha maindasitiri anobatsira kudzora nemasekete emagetsi uye achengetedze.Izvo zvinodikanwa kuti unzwisise maitiro avo ekuumbwa uye matanho ekudzivirira kwekumisikidzwa uye kushandiswa kwakakodzera.Iko kushandiswa kwekudzivirira, kudziya (kuwedzeredza) kudzoreredza uye kutarisisa kwehunyanzvi hwekuita zviratidzo kunove nechokwadi chekushanda kwepamusoro uye kuchengetedza kuita kweAC mabati mumichina yemaindasitiri.
