Ib qhov hluav taws xob siab dua li qhov kev ua haujlwm ib txwm siv hluav taws xob yog siv rau lub rwb thaiv tsev ntawm cov cuab yeej hauv kev sim rau lub sijhawm teev tseg. Yog tias cov rwb thaiv tsev zoo txaus, qhov kev siv hluav taws xob tsuas yog tsim cov xau me me xwb. Yog hais tias qhov hluav taws xob tam sim no ntawm lub rwb thaiv tsev ntawm cov cuab yeej nyob rau hauv kev sim nyob twj ywm nyob rau hauv lub teev nyob rau hauv lub sij hawm teev, nws yuav txiav txim tau hais tias cov cuab yeej nyob rau hauv kev ntsuam xyuas yuav ua hauj lwm yam xyuam xim nyob rau hauv ib txwm ua hauj lwm tej yam kev mob. Nws lub hom phiaj tseem ceeb muaj xws li: kuaj lub rwb thaiv tsev lub peev xwm los tiv thaiv kev ua haujlwm voltage lossis overvoltage; tshuaj xyuas kev tsim khoom lossis kev saib xyuas zoo ntawm cov khoom siv hluav taws xob rwb thaiv tsev; tshem tawm kev puas tsuaj rau rwb thaiv tsev los ntawm cov khoom siv raw, kev ua, lossis kev thauj mus los, txo cov khoom lag luam thaum ntxov; thiab xyuas cov hluav taws xob clearances thiab creepage deb ntawm lub rwb thaiv tsev.
Lub kaw lus xeem feem ntau muaj peb lub ntsiab modules: lub programmable fais fab mov module, lub teeb liab tau txais thiab txias module, thiab lub computer tswj system. Cov qauv ntawm cov khoom siv hluav taws xob tiv thaiv hluav taws xob feem ntau yog suav nrog ntu ntu (voltage regulating transformer, step-up transformer, and power switch), ntu tswj (tam sim no sampling, timeing circuit, alarm circuit), thiab display circuit. Nws txoj haujlwm ua haujlwm yog raws li hauv qab no: tus neeg siv tswj cov zis voltage ntawm cov kauj ruam -up transformer los ntawm kev kho cov voltage regulator; chav tswj kev sib txuas cov kauj ruam- nce lub zog hluav taws xob tom qab tau txais lub teeb liab pib, thiab txiav tawm lub hwj chim thiab lub tswb tom qab cov dej ntws tawm dhau qhov kev txwv lossis lub sij hawm suav rov tas; cov zaub Circuit Court yog siv los tso saib cov zis voltage, to tam sim no, thiab countdown lub sij hawm.
Qhov sib txawv tseem ceeb ntawm cov programmable withstand voltage tester thiab cov twj paj nruag ib txwm muaj nyob rau hauv cov kauj ruam - nce ntu: nws siab -voltage kauj ruam- nce yog tsis kho los ntawm lub mains fais fab thiab voltage regulator, tab sis los ntawm ib tug -chip microcomputer generating ib tug 50Hz los yog 60Hz sine plated Circuit Court yoj teeb liab, uas Tus nqi hluav taws xob tso zis kuj tseem tswj tau los ntawm ib qho -chip microcomputer.
