Isolating switch (disconnect switch) yog ib hom kev hloov khoom siv uas tsis muaj arc extinguishing ntaus ntawv. Nws yog tsuas yog siv los disconnect lub Circuit Court uas tsis muaj load tam sim no thiab cais lub hwj chim mov. Nws muaj qhov pom tseeb qhov cuam tshuam rau hauv lub xeev qhib kom muaj kev nyab xeeb kev tshuaj xyuas thiab kho lwm yam khoom siv hluav taws xob. Nws tuaj yeem ntseeg tau dhau qhov qub thauj khoom tam sim no thiab luv luv-circuit tam sim no hauv lub xeev kaw.
Vim tias nws tsis muaj qhov tshwj xeeb arc extinguishing ntaus ntawv, nws tsis tuaj yeem txiav tawm qhov tam sim no thiab luv-circuit tam sim no. Yog li ntawd, qhov kev rho tawm tuaj yeem ua haujlwm tsuas yog thaum lub tshuab hluav taws xob tau raug txiav tawm los ntawm lub Circuit Court breaker. Nws yog nruj me ntsis txwv tsis pub khiav lag luam nrog kev thauj khoom kom tsis txhob muaj cov khoom siv loj thiab cov xwm txheej ntawm tus kheej. Tsuas yog voltage transformers, xob laim ntes, tsis muaj load transformers nrog excitation tam sim no tsawg dua 2A, thiab tsis muaj-load circuits nrog tam sim no tsawg dua 5A tuaj yeem ua haujlwm ncaj qha nrog kev sib cais hloov.
Load bvreak hloov (LBS) yog ib hom kev hloov khoom nruab nrab ntawm lub Circuit Court breaker thiab kev rho tawm. Nws muaj ib qho yooj yim arc extinguishing ntaus ntawv, uas tuaj yeem txiav tawm qhov ntsuas tam sim no thiab cov khoom siv tam sim no, tab sis tsis tuaj yeem txiav qhov luv luv tam sim no.
Qhov txawv:
Qhov sib txawv ntawm qhov kev hloov pauv, qhov hloov pauv muaj lub tshuab hluav taws xob tua hluav taws xob, uas tuaj yeem tuaj yeem mus txog qhov hloov pauv los ntawm kev tso tawm thermal thaum overloaded.
