Ikizamini cyo kurwanya ibihugu kirashobora gukoreshwa mugupima agaciro ko kurwanya ibikoresho bitandukanye birimo kandi birwanya intangarugero, moto, insinga, ibikoresho by'amashanyarazi, nibindi biri hepfo tuzaganira kubibazo bimwe.
01
Ni iki kisohoka-umuzenguruko kigufi cya tester desticance tester bisobanura iki?
Insinga ndende, moteri zifite umuyaga mwinshi, impinduka, nibindi byashyizwe mubyinshi. Mugihe upima ibintu nkibi, ibisohoka bigufi byumuzunguruko bya test of the testers irashobora kwerekana kurwanya imbere ibisohoka imbere hanze yimbere-voltage isoko ya megger. .
02
Kuki ukoresha inyuma "g" kugirango upime hejuru yo kurwanya
"G" "(umutware wikingiramubiri) yo hanze, imikorere yayo ni ugukuraho ingaruka zubushuhe numwanda mubidukikije kubisubizo byo gupima. Mugihe upima kurwanya hejuru, niba ubonye ko ibisubizo bigoye kubihamana, urashobora gutekereza gukoresha G terminal kugirango ukureho amakosa.
03
Usibye gupima kurwanya, kuki tugomba gupima urutonde rwibipimo na polarisation?
Mu kizamini cyubugenzuzi, abasuhuza agaciro mugihe runaka ntibashobora kwerekana neza ibyiza nibibi byimikorere yo kwipimisha. Ku ruhande rumwe, kubera ibikoresho byo kwinjiza imikorere imwe, ibijyanye no kurwanya inkera bigaragara iyo amajwi ari manini, kandi kurwanya ibihugu bigaragara mugihe ingano ari nto. Binini. Kurundi ruhande, ibikoresho byikigereranyo bifite gahunda yo kwinjiza (Dar) hamwe nuburyo bwa PI) nyuma yo gukoresha voltage ndende.
04
Kuki kugenzura ibikoresho bya elegitoronike bishobora gutanga tester itanga voltage ndende ya dc
Nk'uko ihame ryo guhinduka DC, televiziyo yo kurwanya ibikoresho bya elegitoroniki byateguwe na bateri nyinshi zitangwa numuzunguruko. Imbaraga zo hasi zingufu ziziyongera mubisohoka hejuru dc voltage. Voltage ndende yakozwe ni hejuru ariko imbaraga zisohoka ziri munsi.
Ingamba zo gukoresha amabwiriza yo kurwanya intangarugero
1. Mbere yo gupima, kora ikizamini gifunguye hamwe nikizaruguzi kigufi kumurimo wo kurwanya ibiganiro kugirango urebe niba umufasha wo kurwanya abasuhuza ibisanzwe. Igikorwa cyihariye ni: Fungura insinga ebyiri zihuza, icyerekezo cyikiganza cya swing kigomba kwerekana ubuziraherezo, hanyuma bugufi insinga ebyiri zihuza, icyerekezo kigomba kwerekana zeru.
2. Igikoresho kirimo ikizamini kigomba gucibwa nizindi mbaraga. Nyuma yo gupima birangiye, igikoresho kirimo ikizamini kigomba gusohozwa neza (iminota 2 ~ 3) kurinda ibikoresho n'umutekano ku giti cyawe.
3. Ikizamini cyo kurwanya ibizamini nigikoresho kirimo ikizamini kigomba gutandukana kandi gihujwe usibye ninsinga imwe, kandi hejuru yumuzenguruko umwe igomba kuba isukuye kandi yumye kugirango yirinde amakosa hagati yinsinga.
4. Mugihe cyo kunyeganyega, shyira tester urwanya insulation mumuhanda utambitse, kandi nta muzungugufi ugereranije na buto ya terminal yemerewe mugihe ikiganza kizunguruka. Iyo upimishije hamwe ninsinga, birakenewe guhagarika insinga mugihe ikiganza cya Crank kizunguruka, bitabaye ibyo, bishyuza bikabije bizangiza ikizamini cyo kurwanya ibiganiro.
5. Iyo uzungurutse ikiganza, bigomba gutinda kandi byihuse, no kwihutisha kugeza 120r / min, kandi witondere gukumira amashanyarazi. Mugihe cya swing, iyo icyerekezo kigeze kuri zeru, ntigishobora gukomeza kuzunguruka kugirango uburiganya no kwangiza igiceri mu isaha.
6. Kugirango wirinde kurwanya kumeneka yigikoresho ukigeragezwa, mugihe ukoresheje umutego wo kurwanya ibihugu, aho uhuza igikoresho kirimo ikizamini (nko kwinjiza imbere hagati ya cable shell) bigomba guhuzwa nimpeta yo kurinda.
7. Ikizamini cyo kurwanya ingufu zigomba gutoranywa bitewe nurwego rwa voltage y'ibikoresho biri kugeragezwa. Mubisanzwe, kubikoresho hamwe na voltage yatanzwe munsi ya volt 500, hitamo ikizamini cyo kurwanya ibiganiro bya volt 500 cyangwa 1000; Kubikoresho hamwe na voltage yatanzwe na 500 polts no hejuru, hitamo ikizamini cyo kurwanya insulation cya 1000 kugeza 2500 volt. Muguhitamo ingano nkuru, hagomba kwitabwaho kugirango hatagira ingano yo gupima birenze urugero rwibikoresho byibikoresho byo kwipimisha kugirango birinde amakosa manini kugirango wirinde amakosa manini.
8. Kubuza gukoresha ibizamini byo kurwanya ibijyanye no gupima ikirere cyumurabyo cyangwa ibikoresho biri hafi hamwe nabayobora baltage.
