Cj156 series AC contactor (abbreviated li contactor) yog tsim rau AC 50Hz (muab rau 60Hz), ntsuas qhov hluav taws xob mus rau 660V, ntsuas ua haujlwm tam sim no los ntawm 100A lub zog hluav taws xob, rau cov khoom siv hluav taws xob hauv metallurgy, tshuaj lom neeg kev lag luam, mining, kev tsim kho thiab lwm yam lag luam, raws li qhov ntev-nrhiav kev sib txuas ntawm lub cev muaj zog thiab kev sib txuas, nres nres.

Lub contactor ntawm cov koob no ua tau raws li qhov yuav tsum tau muaj ntawm gb14048.4-2003 low voltage switchgear thiab tswj cov khoom siv hluav taws xob tsis tshua muaj hluav taws xob electromechanical contactor thiab lub cev muaj zog oob khab, thiab cov khoom sib txuas ua ke ua raws li gb14048.5-2001 "tsawg voltage switchgear thiab tswj cov cuab yeej tswj hluav taws xob cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hloov hluav taws xob, cov khoom siv hluav taws xob thiab hluav taws xob" iec60947-.4-1: 2000 yog sib npaug, Iec60947-5-1: 1997 tus qauv.

Sqauv

Lub contactor yog ib tug rotating dav hlau layout strip qauv, nrog rau lub ntsiab kev sib cuag system nyob rau hauv lub sab laug, lub electromagnetic system nyob rau hauv qhov chaw, lub auxiliary tiv tauj rau sab xis, thiab lub auxiliary tiv tauj kuj yuav ntsia tau rau sab laug ntawm lub ntsiab kev sib cuag system. Lub AC electromagnetic system ntawm contactor yog tsim los ntawm ob U-puab electromagnet thiab attraction coil. Armature thiab yoke tau nruab nrog cov cuab yeej tsis siv los txo qhov cuam tshuam kev ntxhov siab thaum lub sijhawm sib nqus kaw, qhov tshwm sim rov qab thaum lub sijhawm sib cuag nqus thiab tso tawm, uas tuaj yeem txhim kho lub neej hluav taws xob thiab lub neej txhua yam. Thiab nruab nrog lub rotating nres qauv kev npaj kom yooj yim saib xyuas thiab tu. Qhov kev sib cuag tseem ceeb yog tus ntiv tes sib cuag nrog ib qho kev tawg, thiab lub hau npog npog yog nias nrog lub zog siab arc resistant yas, uas muaj qhov zoo arc extinguishing kev ua tau zoo thiab muaj zog txhua yam. Qhov kev pabcuam pabcuam yog ob qhov kev sib txuas ntawm kev sib txuas.
