Plub hom phiaj

Cj156 series AC contactor (luv ua contactor) yog tsim rau AC 50Hz (los ntawm 60Hz), ntsuas voltage rau 660V, ntsuas tam sim no ua haujlwm los ntawm 100A fais fab system, rau cov khoom siv hluav taws xob hauv metallurgy, kev lag luam tshuaj lom neeg, kev tsuas, kev tsim kho thiab lwm yam lag luam, ua kev sib txuas ntev, tawg Circuit Court thiab pib, nres, rov qab thiab rov qab txuas nrog nres lub cev muaj zog.

Tus contactor ntawm cov koob no ua tau raws li qhov yuav tsum tau ua ntawm gb14048.4-2003 qis voltage switchgear thiab cov khoom siv tswj hwm qis voltage electromechanical contactor thiab lub cev muaj zog pib, thiab qhov sib txuas lus pabcuam ua raws li gb14048.5–2001 "qis voltage switchgear thiab cov khoom siv tswj hwm hluav taws xob circuit thiab hloov cov ntsiab lus ib feem I electromechanical tswj hwm hluav taws xob cov khoom siv", thiab iec60947-.4-1: 2000 yog sib npaug, Iec60947-5-1: 1997 tus qauv.

Skev tsim kho

Tus contactor yog ib lub qauv ntawm lub dav hlau uas tig tau, nrog rau lub kaw lus tiv tauj tseem ceeb nyob rau sab laug, lub kaw lus electromagnetic nyob rau hauv nruab nrab, lub tiv tauj pabcuam nyob rau sab xis, thiab lub tiv tauj pabcuam kuj tseem tuaj yeem ntsia tau rau sab laug ntawm lub kaw lus tiv tauj tseem ceeb. Lub kaw lus electromagnetic AC ntawm contactor yog tsim los ntawm ob lub electromagnet U-puab thiab lub kauj rub. Armature thiab yoke muaj lub cuab yeej buffer los txo qhov kev ntxhov siab thaum lub sijhawm kaw lub kaw lus magnetic, rov qab los thaum lub sijhawm nqus thiab tso tawm, uas tuaj yeem txhim kho lub neej hluav taws xob thiab lub neej kho tshuab. Thiab nruab nrog lub qauv nres tig rau kev saib xyuas yooj yim thiab txij nkawm. Lub ntsiab tiv tauj yog ntiv tes tiv tauj nrog ib qho chaw tawg, thiab lub hau tua hluav taws arc yog nias nrog lub zog siab arc tiv taus yas, uas muaj kev ua tau zoo tua hluav taws arc thiab lub zog kho tshuab siab. Lub tiv tauj pabcuam yog ob chav tawg choj tiv tauj.
