Cov varistors muaj zog heev tau txais kev nyiam hauv ntau yam lag luam vim lawv muaj peev xwm tiv thaiv cov khoom siv hluav taws xob los ntawm kev nce siab ntawm lub zog hluav taws xob thiab cov xwm txheej overvoltage ib ntus. Cov khoom siv siab heev no tau raug siv ntau dua hauv kev siv hauv kev lag luam los tiv thaiv cov khoom siv rhiab heev thiab xyuas kom meej tias kev ua haujlwm tsis tu ncua.
Hauv kev lag luam tsheb, cov varistors muaj zog siab tau raug koom ua ke rau hauv cov chav tswj hluav taws xob (ECUs) thiab cov tshuab faib hluav taws xob los tiv thaiv cov hluav taws xob nce siab los ntawm xob laim, kev cuam tshuam hluav taws xob, thiab lwm yam kev cuam tshuam hluav taws xob. Qhov no pab txhim kho kev ntseeg tau thiab lub neej ntev ntawm cov khoom siv hluav taws xob tseem ceeb hauv tsheb, thaum kawg txhim kho kev nyab xeeb thiab kev ua tau zoo ntawm lub tsheb.
Ntxiv mus, kev siv cov varistors muaj zog siab hauv kev lag luam hluav taws xob rov ua dua tshiab tau dhau los ua qhov tseem ceeb rau kev tiv thaiv cov inverters hnub ci, cov turbines cua, thiab lwm yam khoom siv hluav taws xob los ntawm kev hloov pauv hluav taws xob thiab kev nce siab los ntawm xob laim. Los ntawm kev muab kev tiv thaiv overvoltage muaj zog, cov varistors no pab txhawb rau kev ruaj khov thiab kev ua haujlwm zoo ntawm cov kab ke hluav taws xob rov ua dua tshiab, yog li txhawb nqa kev hloov pauv mus rau kev tsim hluav taws xob ruaj khov.
Hauv kev lag luam kev sib txuas lus, cov varistors muaj zog siab ua lub luag haujlwm tseem ceeb hauv kev tiv thaiv cov khoom siv hauv network uas muaj zog, xws li cov chaw nres tsheb, antennas, thiab cov khoom siv sib txuas lus, los ntawm cov hluav taws xob uas tuaj yeem tshwm sim los ntawm xob laim lossis kev cuam tshuam ntawm lub zog fais fab. Qhov no pab tswj kev ntseeg tau thiab kev ua haujlwm ntawm cov tes hauj lwm sib txuas lus, kom ntseeg tau tias kev sib txuas lus tsis muaj kev cuam tshuam rau cov lag luam thiab cov neeg siv khoom.
Ntxiv mus, kev lag luam automation sector siv cov varistors muaj zog siab los tiv thaiv cov programmable logic controllers (PLCs), motor drives, thiab lwm yam tshuab tseem ceeb los ntawm kev nce voltage, yog li txo qhov kev pheej hmoo ntawm kev puas tsuaj rau cov khoom siv thiab lub sijhawm tsim khoom tsis ua haujlwm. Qhov no tseem ceeb heev rau cov chaw tsim khoom uas kev ua haujlwm tsis tu ncua yog qhov tseem ceeb rau kev ua tiav cov hom phiaj tsim khoom thiab tswj kev sib tw.
Zuag qhia tag nrho, kev siv cov varistors muaj zog siab hauv ntau yam lag luam qhia txog lawv qhov tseem ceeb hauv kev tiv thaiv cov khoom siv hluav taws xob muaj nqis thiab ua kom ntseeg tau tias muaj kev ntseeg siab ntawm cov kab ke tseem ceeb. Thaum thev naus laus zis txuas ntxiv mus, qhov kev thov rau cov khoom siv tiv thaiv kev kub ntxhov siab no yuav loj hlob, tsav tsheb ntxiv kev tsim kho tshiab thiab kev koom ua ke thoob plaws ntau yam kev lag luam.
