Tsawg-voltage AC contactors feem ntau yog siv los hloov thiab tawm lub zog ntawm cov khoom siv hluav taws xob, uas tuaj yeem tswj cov khoom siv hluav taws xob los ntawm qhov deb, thiab zam kev raug mob ntawm tus kheej thaum hloov thiab tawm lub zog ntawm cov khoom siv. Kev xaiv ntawm AC contactor yog qhov tseem ceeb heev rau kev ua haujlwm ntawm cov khoom siv hluav taws xob thiab cov kab hluav taws xob.
1. Cov qauv thiab qhov tsis sib xws ntawm AC contactor
Nyob rau hauv kev siv, AC contactor ntaus ntawv yuav tsum muaj ib tug compact qauv, ib qho yooj yim mus use, ib tug zoo sib nqus tshuab tshuab rau cov tsiv thiab zoo li qub kev sib cuag, zoo arc extinguishing nyhuv, xoom flashover, thiab me me kub nce. Raws li cov txheej txheem arc extinguishing, nws muab faib ua hom cua thiab lub tshuab nqus tsev, thiab raws li txoj kev ua haujlwm, nws tau muab faib ua hom electromagnetic, pneumatic hom thiab electromagnetic pneumatic hom.
Cov ntsuas hluav taws xob tsis zoo ntawm tus contactor tau muab faib ua qhov siab voltage thiab tsis tshua muaj hluav taws xob, thiab qhov hluav taws xob qis feem ntau yog 380V, 500V, 660V, 1140V, thiab lwm yam.
Hluav taws xob tam sim no muab faib ua alternating tam sim no thiab ncaj qha tam sim no raws li hom. Cov kev ntsuas tam sim no suav nrog cov ntsuas kev ua haujlwm tam sim no, pom zoo cua sov tam sim no, ua tam sim no thiab tawg tam sim no, pom zoo cua sov tam sim no ntawm cov neeg sib cuag thiab lub sij hawm luv luv tiv thaiv tam sim no ntawm contactor, thiab lwm yam. Cov qauv kev sib txuas dav dav muab qhov pom zoo cua sov tam sim no, thiab muaj ntau qhov ntsuas. kev khiav hauj lwm tam sim no coj mus rau qhov pom zoo cua sov tam sim no. Piv txwv li, rau CJ20-63, qhov ntsuas kev ua haujlwm tam sim no ntawm kev sib cuag tseem ceeb tau muab faib ua 63A thiab 40A. 63 nyob rau hauv tus qauv parameter yog hais txog qhov pom zoo cua sov tam sim no, uas muaj feem xyuam rau lub rwb thaiv tsev qauv ntawm lub contactor lub plhaub, thiab cov rated khiav hauj lwm tam sim no muaj feem xyuam rau cov xaiv load tam sim no, muaj feem xyuam rau lub voltage theem.
AC contactor coils tau muab faib ua 36, 127, 220, 380V thiab lwm yam raws li qhov voltage. Tus naj npawb ntawm tus ncej ntawm lub contactor muab faib ua 2, 3, 4, 5 ncej thiab lwm yam. Muaj ob peb khub ntawm pab neeg sib cuag raws li ib txwm qhib thiab ib txwm kaw, thiab raug xaiv raws li kev tswj hwm kev xav tau.
Lwm yam tsis muaj xws li kev sib txuas, tawg lub sij hawm, txhua yam lub neej, hluav taws xob lub neej, siab tshaj plaws kev khiav hauj lwm zaus, siab tshaj plaws tso cai thaiv kab, sab nraud qhov ntev thiab installation qhov ntev, thiab lwm yam.Classification ntawm contactors
