Ibikoresho by'amashanyarazi bifite ingufu nyinshi bigomba gukomeza kubika neza mugihe gikora, bityo rero Urutonde rwibigeragezo bigomba gukorwa kuva mugitangira ibikoresho.Ibi bizamini birimo: Ibizamini Byibikoresho Muburyo bwo Kubyaza umusaruro, Ikizamini giciriritse mugikorwa cyumusaruro, Ibizamini byujuje ubuziranenge n’uruganda, Koresha ibizamini byo Kwishyiriraho ahabigenewe, hamwe n’ibizamini byo gukumira bikingira kurinda no gukora mugihe cyo gukoresha.Ubuhamya bwibikoresho byamashanyarazi nubushakashatsi bwo gukumira nubushakashatsi bubiri bwingenzi.Repubulika y’Ubushinwa Amategeko y’inganda zikoresha amashanyarazi n’amategeko y’igihugu: DL / T 596-1996 “Uburyo bwo Kwipimisha Kwirinda Ibikoresho By’amashanyarazi” na GB 50150-91 “Ibizamini byo Gusimbuza ibikoresho by'amashanyarazi” Kugaragaza Ibirimo n'ibisobanuro bya buri bushakashatsi.

2. Ubushakashatsi bwo Kwirinda

Ikizamini cyo Kwirinda Ikizamini cyibikoresho byamashanyarazi nigipimo cyingenzi kugirango tumenye neza ibikoresho.Nyuma y'Ikizamini, Imiterere y'Ibikoresho by'Ibikoresho irashobora gufatwa, Akaga muri Insulation karashobora kuboneka mugihe, kandi uburinzi burashobora kuvaho.Niba hari Ikibazo gikomeye, ni ngombwa gusimbuza ibikoresho kugirango wirinde igihombo kidasubirwaho, nkumuriro w'amashanyarazi cyangwa ibyangiritse byatewe no kunanirwa kwizana mugihe gikora.

Ubushakashatsi bwo Kwirinda Gukingira bushobora kugabanywamo ibyiciro bibiri: Imwe ni Igerageza ridasenya cyangwa igeragezwa ryiranga insulasiyo, ryerekeza ku bipimo bitandukanye biranga ibipimo byapimwe kuri voltage nkeya cyangwa nubundi buryo butazangiza ibyangiritse, harimo no gupima ubwishingizi, kumeneka, Gutakaza Dielectric Tangent, nibindi hanyuma umenye niba Insulation ifite ibitagenda neza.Ubushakashatsi bwerekanye ko ubu buryo ari ingirakamaro, ariko ntibushobora gukoreshwa kugirango umenye neza imbaraga z'amashanyarazi ya Insulation.Ibindi Nibizamini Byangiza cyangwa Ikizamini Cyumuvuduko.Umuvuduko Ukoreshwa Mubizamini Birarenze Kurenza Umuvuduko Ukoresha Ibikoresho, kandi Ibisabwa Kwipimisha Insulation Birakaze cyane.By'umwihariko, Hariho Akaga gakomeye ko Kugaragaza no Gukusanya Ibitagenda neza, no Kureba ko Insulation ifite Imbaraga Z'amashanyarazi, Harimo DC Yihanganira Umuvuduko, Itumanaho Ryihanganira Umuvuduko, n'ibindi. Ibyangiritse.

3. Ikizamini cyo gutanga ibikoresho by'amashanyarazi

Kugirango Dukemure Ibikenewe Byububiko Bwamashanyarazi Nubushakashatsi bwo Gusimbuza Ibikoresho Byamashanyarazi, no Gutezimbere Gutezimbere no Gukoresha Ikoranabuhanga Rishya Kubushakashatsi bwo Gusimbuza Ibikoresho Byamashanyarazi, Igipimo cyigihugu GB 50150-91 "Ikigereranyo cyogusimbuza ibikoresho byamashanyarazi" Cyerekana neza Ibirimo Kandi Ibisobanuro byubushakashatsi butandukanye.Mubyongeyeho Kuri Bimwe Mubigeragezo byo Kwirinda, Ubushakashatsi bwo Gusimbuza Ibikoresho by'amashanyarazi Nanone Harimo Ubundi Bugeragezwa Bwiranga, Nka Transformer DC Kurwanya no Kugereranya, Ikigereranyo Cyumuzenguruko Wizunguruka, Ibindi.

4. Ihame shingiro ryokwirinda gukumira

4.Agaciro ko Kurwanya Kurwanya Birashobora Kugaragaza neza Inenge Ziterwa na Insulation, nkubushuhe bwuzuye, kwanduza, ubushyuhe bukabije no gusaza.Igikoresho Cyakoreshejwe Cyane Cyane Kugerageza Kurwanya Kurwanya Kurwanya ni Ikizamini cyo Kurwanya Kurwanya (Ikizamini cyo Kwirinda).

Ibizamini byo Kurwanya Kurwanya (Kwipimisha Kwigunga) Mubusanzwe ufite Ubwoko nka 100 Volts, 250 Volts, 500 Volts, 1000 Volts, 2500 Volts, na 5000 Volts.Ikizamini cyo Kurwanya Kurwanya Igikoresho kigomba gukoreshwa mu buryo buhuye na DL / T596 “Uburyo bwo Kugerageza Gukumira Ibikoresho By’amashanyarazi”.

4.2 Ikizamini gisohoka

Umuvuduko Wibizamini Rusange DC Kurwanya Kurwanya Ibiri munsi ya 2.5KV, Bikaba Hasi Kuruta Umuvuduko Ukora Wibikoresho bimwe byamashanyarazi.Niba Utekereza ko Umuvuduko Wapima Ikizamini cya Insulation Resistance Ikizamini kiri hasi cyane, urashobora gupima imyuka iva mubikoresho byamashanyarazi wongeyeho DC Umuvuduko mwinshi.Ibikoresho Byakoreshejwe Mubisanzwe Gupima Kumeneka Ibiriho Harimo Impinduka Zikomeye Zihinduranya na DC Amashanyarazi menshi.Iyo Ibikoresho bifite Ibitagenda neza, Kumeneka Kugenda munsi yumuvuduko mwinshi ni munini cyane kuruta iyo munsi ya voltage nkeya, ni ukuvuga, Kurwanya Insulation munsi yumuvuduko mwinshi ni bito cyane kurenza iyo munsi ya voltage nkeya.

Nta tandukaniro ryinshi riri hagati yo Kumeneka Kugenda no Kurwanya Kurwanya Ubuvuzi Bwihanganira Ibikoresho bipima ibipimo bya voltage, ariko ibipimo bya Leakage bigezweho bifite ibimenyetso bikurikira:

(1) Umuvuduko wikizamini urarenze cyane uwuwipimishije.Ibitagenda neza byubwishingizi ubwabyo birashyirwa ahagaragara byoroshye, kandi hari ibitagenda neza bihinduka bitarinjira.

4.3 DC Ihangane Ikizamini cya Voltage

DC Ihangane Ikizamini cya Voltage Ifite Hejuru

Itumanaho Ihangane na Voltage Igeragezwa Rimwe na rimwe Bituma Intege nke Zimwe Mubisanzwe Byigaragaza.Niyo mpamvu, Birakenewe Gukora Ubushakashatsi Kubirwanya Kurwanya Kurwanya, Igipimo cya Absorption, Kumeneka Ibiriho na Dielectric Gutakaza Mbere Yubushakashatsi.Niba igisubizo cyikizamini gishimishije, Itumanaho rihanganira ikizamini cya voltage kirashobora gukorwa.Bitabaye ibyo, Bikwiye gukemurwa mugihe, kandi itumanaho ryihanganira ikizamini cya voltage kigomba gukorwa nyuma yuko buri ntego yujuje ibisabwa kugirango birinde kwangirika bitari ngombwa.

4.5 Ikizamini Cyibura rya Dielectric Tgδ

Igihombo cya Dielectric Tgδ Nimwe mumigambi Yibanze Yerekana Imikorere Yubwishingizi.Igihombo cya Dielectric Tgδ Yerekana Ikiranga Ikiranga Igihombo.Irashobora Kuvumbura Muburyo Bwuzuye Muri rusange Ibikoresho Byamashanyarazi Byatewe no Gutose, Kwangirika, no Kwangirika, Nka Nenge Yaho Yibikoresho bito.

Kugereranya Ubuvuzi Bwihanganira Ikigereranyo Cyumubyigano Kurwanya Kurwanya no Kumeneka Ibizamini Bigezweho, Ikintu Cyatakaye cya Dielectric Tgδ Ifite inyungu Zingenzi.Ntaho ihuriye na Voltage yikizamini, Ingero yikigereranyo Ingano nibindi bintu, kandi biroroshye gutandukanya Impinduka zokwirinda ibikoresho byamashanyarazi.Kubwibyo, Dielectric Yatakaye Ikintu Tgδ Nimwe Mubizamini Byibanze Byibizamini Byokwirinda Byibikoresho Byamashanyarazi Byinshi.

Igihombo cya Dielectric Tgδ Irashobora kuba ingirakamaro mugushakisha ibitagenda neza bikurikira:

(1) Ubushuhe;(2) Kwinjira Umuyoboro uyobora;.(4) Kwikingira biranduye, byangiritse, kandi birasaza.
