Isolating Switches Raws li Voltage Levels

Tsawg voltage rho tawm hloov
Thaum kho cov khoom siv hluav taws xob [5], nws yog ib qho tsim nyog yuav tsum tau txiav cov khoom siv hluav taws xob, cais qhov kho ntawm qhov chaw nyob, thiab tswj qhov kev sib cais kom zoo. Nws yuav tsum tau tiv thaiv overvoltage withstand voltage theem ntawm nws cov ntsiab lus tawg. Riam hloov yog lub cuab yeej hloov pauv uas ua haujlwm raws li kev sib cais lub zog. Cov riam hloov uas cais cov khoom siv hluav taws xob kuj tseem hu ua kev hloov pauv hloov. Kev rho riam hlais feem ntau yog cov khoom siv tsis-load-off thiab tsuas tuaj yeem txuas lossis txiav "qhov tsis zoo tam sim no" (xa mus rau lub capacitive tam sim no ntawm cov tsheb npav voltage, luv cables, lossis voltage transformers). Qee lub riam riam kuj muaj qee qhov kev tawg, uas tuaj yeem siv los txuas lossis txiav ib feem ntawm cov khoom siv hluav taws xob lossis cov khoom siv ua tiav nyob rau hauv cov xwm txheej tsis raug thaum nws lub peev xwm tawg yog tsim nyog rau qhov yuav tsum tau tawg tam sim no. Lub riam hloov siv los ua ib qho kev sib cais fais fab yuav tsum ua kom tau raws li qhov kev sib cais, uas yog, qhov kev hloov ntawm qhov tawg yog qhov pom tseeb thiab qhov tawg ntawm qhov sib txawv yog tsim nyog. Cov riam hloov thiab fuse yog sib xyaw ua ke los tsim ib chav tsev, uas yog hu ua riam hloov fuse ua ke khoom siv; Thaum cov khoom txav tau (tsav sib cuag) ntawm rab riam hloov yog tsim los ntawm cov khoom siv fuse nrog lub fuse txuas, nws yog hu ua fuse hom riam hloov. Riam hloov fuse ua ke thiab cov khoom siv ntxiv xws li kev khiav hauj lwm qib, lub caij nplooj ntoos hlav, thiab arc riam tuaj yeem ua ke los tsim kev hloov pauv. Lub load hloov muaj peev xwm ua los yog tawg load tam sim no nyob rau hauv tsis muaj kev txhaum thiab muaj ib tug tej yam luv luv-circuit tiv thaiv muaj nuj nqi.
