Umutwaro wa kabiri wa transformateur yubu uhindura imikorere yacyo neza.Mubisanzwe, nukuvuga umutwaro wa kabiri, niko ikosa rya transformateur.Mugihe cyose umutwaro wa kabiri utarenze uwashizeho igiciro cyagenwe, uwabikoze agomba kwemeza ko ikosa ryakozwe na transformateur riri murwego rwukuri cyangwa murwego rwo hagati ya 10% ikosa.Imbere.Kubwibyo, mugihe cyo gukoresha transformateur yubu, umutwaro wacyo wa kabiri nu mutwaro wa kabiri ugomba kumenyekana.Gusa iyo umutwaro nyirizina wa kabiri uri munsi yumutwaro wa kabiri wagabanijwe urashobora kwibeshya.
Mugihe ikosa rya transformateur iriho irenze agaciro kagenwe nuwabikoze, bizagira ingaruka mbi kubikoresho bya kabiri nko kurinda relay hamwe nibikoresho bipima.Ingamba zindishyi zifatwa mugihe ikosa rya transformateur irenze agaciro kagenwe nuwabikoze.
(1) Ongera igice cyambukiranya igice cya kabili ya kabiri cyangwa kugabanya uburebure bwumugozi.Kongera igice cyambukiranya igice cya kabili ya kabiri ya loop ya none cyangwa kugabanya uburebure bwumugozi mubyukuri bigabanya impedance ya wire ya kabiri kandi bigabanya umutwaro wa kabiri.
.Igiceri cya kabiri cyibice bibiri byimyanya ihinduka hamwe nikigereranyo kimwe cyo guhinduka hamwe nibiranga bikoreshwa murukurikirane.
.Ukurikije ihame rivuga ko gutakaza umurongo bigereranywa na kare ya none, birashobora kugaragara ko gutakaza umurongo biba bito kandi inzitizi ziva hanze zikaba nini, bityo ubushobozi bwo gutwara imizigo bugashimangirwa.
(4) Kugabanya umutwaro wa kabiri.Hitamo relay hamwe nini nini igenamigambi ishoboka, kuko diameter ya wire ya coil ya relay hamwe nigikoresho kinini cyo gushiraho ni ndende kandi umubare wimpinduka ni muto, bityo impedance nayo ni nto;cyangwa uhindure urukurikirane rwihuza rwa relay coil kumurongo ugereranije, kuberako impedance yuruhererekane rwihuza Impedance nini kuruta guhuza isano;cyangwa ukoreshe microcomputer yo kurinda ibikoresho kugirango usimbuze amashanyarazi.
Ikizamini cyo kurwanya insulasiyo ya transformateur igezweho
1. Intego yikizamini
Irashobora kubona neza inenge muri rusange, nk'umwanda, umwanda, kwinjira, gusenyuka, nibindi, hamwe n'ubushyuhe bukabije hamwe nubusaza.Gupima ubukana bwokwirinda ingabo ya nyuma kubutaka birashobora kumenya neza amazi yinjira nubushuhe bwamazi ya transformateur ya capacitive.
2. Ikigereranyo
Gupima ubukana bwokwirinda kwizuba ryibanze kugeza kumurongo wa kabiri no kumurongo, hamwe nuburwanya bwokwirinda kwa buri cyiciro cya kabiri hamwe na kase.
Gupima ubukana bwokwirinda hagati yibice byambere bizunguruka, ariko ntabwo ari ngombwa gupima igihe bidashobora gupimwa kubera impamvu zubatswe.
Gupima izirinda izirinda icyiciro cya nyuma ingabo ya capacitive current transformateur.
HV Hipot GDHG-306D Ihindura Ikizamini Cyuzuye
3. Guhitamo ibikoresho
Gupima ubukana bwokwirinda hagati yimikorere nyamukuru ya transformateur iriho, ingabo yanyuma, kuzunguruka kwa kabiri nubutaka.Ikizamini cyo kurwanya insuline ya 2500V no hejuru yacyo kigomba gukoreshwa mukubungabunga cyangwa gutanga ibizamini no kwipimisha.
4. Isesengura ry'ingaruka n'ingamba zo kugenzura
kugirango wirinde kugwa hejuru
Irinde ibikomere kugwa
gukumira amashanyarazi
Mbere yo guhagarika no guhuza umurongo wikizamini, transformateur iri kugeragezwa igomba gusezererwa burundu hasi kugirango hirindwe amafaranga asigara hamwe na voltage iterwa no kugirira nabi abantu kandi bikagira ingaruka kubisubizo byapimwe.Icyuma gikoresho cyikizamini kigomba kuba gishingiye ku kwizerwa, kandi ikizamini gikoresha igikoresho kigomba guhagarara ku cyuma gikingira cyangwa kwambara icyuma gikoresha ibikoresho.Ikizamini cyo gupima kigomba guhuzwa nuwabishinzwe, kandi ntibyemewe.
Shiraho ubwugamo bufunze hafi yikizamini, umanike ibimenyetso "uhagarare, ibyago byinshi bya voltage", kandi ushimangire gukurikirana.Shimangira kugenzura no gushyira mubikorwa gahunda yo kuririmba ikora.
5. Kwitegura mbere yikizamini
Sobanukirwa nimiterere yumurima nuburyo bwo kugerageza ibikoresho biri kugeragezwa.
Ibikoresho n'ibizamini byuzuye
Fata ingamba z'umutekano na tekiniki ahakorerwa ibizamini
Abapima agasanduku bagomba gusobanura ibikubiye mu kazi, ibice bizima, ingamba z'umutekano ku rubuga, aho akaga gakorerwa, kandi bagasobanura igabana ry'umurimo n'ibizamini.
6. Intambwe yikizamini cyo murwego nibisabwa
Reba megohmmeter ubwayo mbere yikizamini, shyira urwego rwa megohmmeter mu buryo butajegajega, ubanza ikizamini kigufi cyumuzunguruko hanyuma hanyuma ufungure uruziga, mugihe uhujwe no gutanga amashanyarazi ya megohmmeter ikosowe, insinga ya Uno izahita “L” na "E" "itumanaho, ibyerekanwa bigomba kuba zeru; iyo bifunguye, mugihe ingufu zafunguye cyangwa umuvuduko wagenwe ugaragara muri megohms, icyerekezo kigomba kuba" ∞ ". Mugihe wiring, uhuze itumanaho ryambere, hanyuma hanyuma uhuze umurongo wa voltage ndende.
Terminal "E" kuri megohmmeter nubutaka bwubutaka bwikizamini, aricyo pole nziza, kandi "L" ni umuyagankuba mwinshi wibikoresho byibizamini, aribyo pole mbi.“G” ihujwe na terefone ikingira, ari yo nkingi mbi.
7. Ikizamini cyo kurwanya insulation
Gupima ubwirinzi bwokwirinda kwambere kwihinduramatwara ihinduranya kugeza kumurongo wa kabiri hamwe nigikonoshwa
Gupima ubukana bwokwirinda hagati ya transfert ya kabiri ya transformateur nubutaka
Gupima ubukana bwokwirinda ingabo ya nyuma ya transformateur
Gupima ubukana bwokwirinda kwambere
Ihinduranya ryibanze P1 na P2 ya transformateur iriho ubu irazunguruka-mugufi hamwe ninsinga ngufi, imirongo yose ya kabiri irazunguruka mugihe gito, kandi ingabo ya nyuma irazunguruka-hasi.(Niba ubuso bwa transformateur buremereye cyane, hagomba gushyirwaho impeta ikingira kandi igahuzwa na "G" ya megger hamwe na wire.)
Ikirangantego cya "L" cyumubyigano mwinshi wikigereranyo cyahujwe na primaire yambere ya P1 na P2 ya terefone ihinduranya cyangwa insinga ngufi, kandi terminal "E" irahagarara.
Nyuma yo kugenzura insinga, kanda buto "Tangira", hanyuma metero itangire gukora.Nyuma yiminota 1, agaciro ko kurwanya insulation kazandikwa.Ikizamini kimaze kurangira, metero igomba guhagarikwa kurugero, hanyuma ukande buto "guhagarara" kugirango usubukure metero.
Hanyuma, gusohora igice cyikizamini cya transformateur yubu.
