Ibibazo murubuga rwibizamini bya loop resistance test

Mugihe ikizamini cyo kurwanya loop (nanone cyitwa test resistance resistance) cyakozwe hakurikijwe ihame rya gakondo ryageragejwe mu murima, byagaragaye ko hari ikibazo rusange.Mugihe umuyoboro wa voltage uhuza ibizamini uri mubitumanaho nabi cyangwa uruziga rufunguye, ikizamini nacyo kizerekana agaciro, kandi ibihe bikurikira bizabaho:

                                                                           HV HIPOT GDHL-200A / 100A Ikizamini cya Automatic Loop Resistance Tester

.Muri iki kibazo, kubera ko itandukaniro ritandukanye rya voltage yinjizwa na amplifier ari 0, agaciro k'ikizamini kerekanwa nigikoresho kegereye 0. Niba ikizamini gifite uburambe bwikizamini gihagije, gishobora guca urubanza ko umurongo wikizamini kidasanzwe cyumubyigano wibikoresho umuzenguruko ntusanzwe hanyuma usubire mubikoresho bya voltage.Nyuma yinzira idasanzwe yikizamini ikuweho, ibisubizo byanyuma byikizamini birashobora kuboneka.

(2) Guhuza umuyoboro wa voltage ni bibi.Mubihe byinshi, ama terinal ya break break yamashanyarazi azabyara firime ya oxyde cyangwa firime ya peteroli hejuru yinyuma ya terminal nyuma yo gukora igihe kirekire.Iyo voltage igeragezwa kubarwanya umuzunguruko ifatanye kumurongo wanyuma, guhura nabi birashoboka.Iyo clip yipimishije ya voltage ubwayo nayo itanga uburyo bwo guhangana kwihuza, agaciro kirwanya guhuza ni kimwe nigiciro cyimbere cyimbere cyumubyigano wa voltage.bizagira ingaruka zikomeye kubisubizo byikizamini.

. .Muri iki gihe, bisi nzima inyura muri capacitor hamwe numwuka nkibikoresho, bikabangamira imirongo ibiri yikizamini cya voltage yikizamini.Bitewe no kwivanga, imirongo yo kugura voltage yo kugerageza loop irwanya ni bibiri.Uburyo butandukanye bwa voltage igaragara kumpera.
