Xaiv cov koom haum DC
Txoj kev khiav hauj lwm ntawm kev sib txuas ncaj qha yog tib yam nkaus li ntawm AC contactor, Txawm li cas los, qhov sib txig ntawm lub zog uas tau muab los ntawm cov cua hauv qab no tso tawm thaum lub sij hawm dc tawg, thiab lub zog-zog arc yog tsim nyob rau ntawm lub caij so tawg, yog li ntawd, lub arc extinguishing kev ua ntawm dc contactor yuav tsum tau siab tshaj li qhov ntawm AC contactor. Qhov loj-tau ntes dc contactor feem ntau yog siv tib qho dav hlau dav dav dav dav dav dav dav ntawm cov qauv zuag qhia tag nrho, uas yog lub tshuab tua hluav taws txaij tawm nrog lub qhov rooj tua hluav taws hlawv, qhov nrug deb ntev yog ntev thaum tawg. Qhov muaj peev xwm tsawg tsawg tus neeg tau txais kev pabcuam raug rhais ob qhov kev rhuav tshem ob npaug ntawm peb lub sijhawm.
Cov ntsiab lus hauv qab no yuav tsum raug sau tseg thaum xaiv dc contactor:
1. Qhov sib npaug tam sim no ntawm tus tiv tauj tseem ceeb yog ntau tshaj 1.3 zaus teev cov khoom tau teev tseg.
2. Qhov sib npaug ntawm qhov kev sib cuag tseem ceeb tshaj qhov siab tshaj los yog sib npaug ntawm qhov ntsuas ntawm cov khoom pov thawj.
3. Tus naj npawb thiab hom neeg yuav tsum tau ua raws li qhov yuav tsum tau tswj xyuas ntawm Circuit Court.
4. 220V los yog 380V tuaj yeem siv thaum lub Circuit Court yooj yim thiab tsawg dua cov cuab yeej siv hluav taws xob.
Thaum lub Circuit Court yog siv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob ntev, 36V, 110V lossis 127V xaiv tau.
5. Thaum lub sijhawm tshaj tawm ntawm qhov loj thiab qhov tshaj tawm ntawm qhov tshaj tawm tshaj qhov teev nqi, tus ntaus contactor nrog lub siab dua cov nqi tam sim no yuav tsum raug xaiv. Txwv tsis pub, txoj kev sib cuag tseem ceeb heev, uas yuav ua rau melting ua ke, uas ua rau lub sij hawm tsav tsheb poob haujlwm.
