Purpose

Cj156 series AC contactor (yakapfupikiswa secontactor) inokodzera AC 50Hz (yakatorwa ku60Hz), yakayereswa voltage kusvika ku660V, yakayerwa kushanda ikozvino kubva ku100A simba system, yemagetsi zvigadzirwa musimbi, indasitiri yemakemikari, migodhi, kuvaka uye mamwe maindasitiri, senge kureba-kure-kure kutenderera uye kumisa dhizaini kutanga, kumisa dhizaini dhizaini, kudzoreredza dhizaini.

Iyo yekubatanidza yeiyi nhevedzano inosangana nezvinodiwa zve gb14048.4-2003 yakaderera voltage switchgear uye yekudzora midziyo yakaderera voltage electromechanical contactor uye motor starter, uye yekubatsira yekubatanidza chikamu inoenderana ne gb14048.5-2001 "yakaderera voltage switchgear uye yekudzora midziyo yekudzora dunhu midziyo yemagetsi uye switch zvinhu chikamu I electromechanical control circuit, magetsi appli iec60947-.4-1:2000 yakaenzana, Iec60947-5-1: 1997 standard.

Schimiro

Iyo contactor inotenderera plane marongerwo strip chimiro, ine main contact system kuruboshwe, iyo electromagnetic system iri pakati, yekubatsira yekubata kurudyi, uye yekubatsira yekubata inogona zvakare kuiswa kuruboshwe rweiyo main contact system. Iyo AC electromagnetic system yekubata inoumbwa nekaviri U-yakaita magineti emagetsi uye inokwezva coil. Armature uye joko zvakashongedzerwa nebuffer mudziyo kudzikisa kushushikana kwemaitiro panguva yekuvhara magineti, rebound phenomenon panguva yekubata kuyamwa uye kuburitsa, izvo zvinogona kuvandudza zvakanyanya hupenyu hwemagetsi uye hupenyu hwemuchina. Uye yakashongedzerwa neinotenderera yekumira dhizaini gadziriro yekutarisa uye kugadzirisa nyore. Iyo huru yekubata igunwe rekubata nekamwe break point, uye iyo arc yekudzima chivharo inotsikirirwa neakakwira simba arc inopikisa purasitiki, ine yakanaka arc yekudzima kuita uye yakakwirira mechanical simba. Iyo yebetsero yekubatanidza ndeye kaviri kutyora zambuko kusangana.
