Ikizamini cyo Kurwanya Ibikwiranye Birakwiriye Gupima Agaciro Kurwanya Ibikoresho Bitandukanye Bikwirakwiza hamwe no Kurwanya Kurwanya Impinduka, Moteri, insinga nibikoresho byamashanyarazi, kugirango barebe ko ibyo bikoresho, ibikoresho byamashanyarazi nimirongo ikora mubihe bisanzwe kugirango wirinde amashanyarazi, impanuka n ibikoresho. Ibyangiritse.
Ibibazo Bikunze Kwipimisha Kurwanya Kurwanya Nibikurikira:
1. Iyo Gupima Ubushobozi bwo Kurwanya Imizigo, Ni irihe sano riri hagati yumusaruro Mugufi-Umuzunguruko Wibihe Byibizamini bya Insulation Resistance hamwe namakuru yapimwe, kandi kuki?
Ingano Y Ibisohoka Bigufi-Umuzenguruko Wibihe Byibizamini bya Insulation Kurwanya Ibizamini Birashobora Kugaragaza Ingano Yimbere Kurwanya Imbere Yumuriro-Umuvuduko mwinshi Imbere muri Megger.
Ibizamini Byinshi Byokugerageza Kwibanda Kumutwaro Ufite ubushobozi, nkinsinga ndende, moteri hamwe na Winding nyinshi, na Transformers.Kubwibyo, Iyo Intego Yapimwe Ifite Ubushobozi, Mugutangira Igikorwa Cyikizamini, Inkomoko Yumubyigano Winshi Mubizamini bya Insulation Resistance Tester igomba kwishyuza Capacitor binyuze mukurwanya kwayo imbere, hanyuma gahoro gahoro ikarishye voltage kumasoko yinyongera yumuriro mwinshi mwinshi Ikizamini cyo Kurwanya..Niba Ubushobozi Agaciro Kintego Yapimwe Ninini, Cyangwa Kurwanya Imbere Yumuriro-Umuvuduko mwinshi ni munini, inzira yo kwishyuza izatwara igihe kirekire.
Uburebure bwayo bushobora kugenwa nigicuruzwa cya R Imbere na C Umutwaro (Igice: Icya kabiri), Nukuvuga, T = R Imbere * C Umutwaro.
Kubwibyo, Mugihe c'Ikizamini, Birakenewe Kwishyuza Umuyoboro Ufite Ubushobozi Kuri Umuvuduko wikizamini, kandi Umuvuduko wo Kwishyuza DV / Dt Uhwanye nu kigereranyo cyumuriro Wishyurwa I Kuri Ubushobozi Bwumutwaro C. Nukuvuga, DV / Dt = I / C.
Kubwibyo, Ntoya Kurwanya Imbere Ninshi Nini Yishyuza Ibiriho, Byihuse Ibisubizo byikizamini bizaba bihamye.
2. Ni ubuhe butumwa bw'uruhande rwa “G” Kugaragara?Mugihe Cyinshi Cyumuvuduko Ukomeye-Kurwanya Ibizamini, Kuki Bisabwa Guhuza Terminal "G" hanze?
Iherezo rya "G" Ubuso ni Ikingira.Imikorere ya Shielding Terminal Nugukuraho Ingaruka Yubushuhe Numwanda Mubidukikije Ibizamini Kubisubizo byo gupima.Hanze ya “G” Isohora Ibisohoka Ibicuruzwa Byageragejwe, Kugirango Ibimeneka Bitanyura Mubizamini By’ibizamini byo hanze, kandi bikuraho ikosa ryatewe no kuva kumashanyarazi.G Terminal ikoreshwa mugihe ugerageza Kurwanya Kurwanya.
Mubisanzwe Tuvuze, G Terminal Irashobora Gufatwa Kurenza 10G.Ariko, Uru Rwego rwo Kurwanya Ntabwo Rwukuri.Iyo Isukuye kandi Yumye Nubunini bwikintu cyikizamini ni gito, Irashobora guhagarara itapimye 500G kuri G.Mubidukikije kandi Byanduye, Agaciro ko Kurwanya Agaciro Nako gasaba G Impera.By'umwihariko, Niba Usanze Ibisubizo Biragoye Guhagarika Iyo Upimye Kurwanya Kurwanya, Urashobora Gutekereza Gukoresha G Terminal.Menya kandi ko Shielding Terminal G idahujwe na Shielding Layeri, ariko Kuri Insulator hagati ya L na E Cyangwa Kuri Cyuma Cyinshi, Ntabwo Kuri Izindi nsinga ziri kugeragezwa.
3. Ni ukubera iki bidasabwa gupima gusa agaciro keza ko guhangana n’igihe cyo gupima insulasiyo, ariko kandi no gupima igipimo cya Absorption na Index ya Polarisation.Ingingo ni iki?
PI Nibipimo bya Polarisiyasi, Bisobanura Kugereranya Hagati yo Kurwanya Kurwanya Iminota 10 Na Kurwanya Kurwanya Iminota 1 Mugihe Ikizamini Cyubwishingizi;
DAR Nibipimo bya Dielectric Absorption, Bisobanura Kugereranya Hagati Yumwanya wo Kurwanya Iminota 1 Nukwirinda Kwirinda kwa 15s mugihe cyo Kwipimisha;
Mu kizamini cyo Kwikingira, Agaciro Kurwanya Kurwanya Agaciro Mugihe runaka Ntishobora Kugaragaza Byuzuye Imikorere Yokwirinda Yikigereranyo.Ibi Biterwa nimpamvu ebyiri zikurikira.Ku ruhande rumwe, Kurwanya Kurwanya Imikorere imwe Yibikoresho Byibikoresho ni bito iyo Umubumbe Nini., Kurwanya Kurwanya Kugaragara Kugaragara Iyo Ijwi Rito.Kurundi ruhande, ibikoresho byo kubika bifite inzira yikigereranyo cya Absorption hamwe na Polarisiyasi yuburyo bwishyurwa nyuma yumuriro mwinshi ukoreshwa.Kubwibyo, Sisitemu Yingufu Zisaba Gupima Igipimo cya Absorption-Ikigereranyo cya R60s na R15s, N'igipimo cya Polarisiyasi-Ikigereranyo cya R10min na R1min Mu kizamini cya Insulation ya Transformers, insinga, moteri nibindi bihe byinshi, kandi ukoreshe ibi Amakuru yo Kumenyekanisha Ibyiza Byiza cyangwa bibi.
4. Ni ukubera iki Ikizamini cya Electronic Insulation Resistance Ikizamini gishobora kubyara ingufu nyinshi za DC mugihe zikoreshejwe na bateri nyinshi?Ibi Bishingiye ku Ihame rya DC Guhindura.Umuyagankuba Ntoya Utanga Umuvuduko Uzamurwa Kumurongo Wisohoka DC Umuyoboro Binyuze Mubitunganyirize Byumuzunguruko.Umuvuduko mwinshi wabyaye uri hejuru ariko imbaraga zisohoka ni nto (Ingufu nkeya na Ntoya).
Icyitonderwa: Nubwo imbaraga ari nto cyane, ntabwo bisabwa gukoraho kugiti cyawe Ikizamini, hazakomeza kubaho ibyiyumvo.
