Muna Nyamavhuvhu, mushure mekutengesa matekiniki eHV Hipot akaenda kuXiangyang.Chinangwa cherwendo urwu chaive chekupa impulse voltage debugging services ku Xiangyang Power Supply Company.
Mushure mekusvika panzvimbo, nerubatsiro uye nekubatana kwemutengi, kuiswa kwemheni impulse voltage generator kuchaitwa.
Pa-saiti debugging yeGDCY-400kV mheni impulse voltage jenareta
Pa-saiti bhora kureba kureba: bhora remuviri kureba uye chopper bhora kureba kureba (3000/200 / kuyerwa)
Pa-saiti inomhanya-mubvunzo: 30KV yakanaka uye isina kunaka polarity akawanda bvunzo (sangana T1=1.2±30%/T2=50±20%us/TC=2 kusvika 6us)
Pa-saiti simba bvunzo: yakatarwa voltage 80% kubuda
Pa-saiti theoretical uye kudzidzira kudzidzira:
Mutengi tsika - simulated bvunzo chigadzirwa bvunzo: 10KV simba transformer
1. Full wave test
Test zvinodiwa: bvunzo voltage 75KV, waveform nguva T1=1.2±30%/T2=50±20%us
Kushanda mumunda: kushandisa maviri-nhanho voltage kubuda
Pane-saiti wave modulation:
Wave musoro kuramba: 150Ω yedanho rekutanga, 500Ω yechipiri nhanho (2 1KΩ yakafanana)
Wave muswe kuramba: 1st nhanho 45Ω, 2nd nhanho 45Ω
Kuedza kushanda uye waveform:
2. Cutoff test
Zvinodiwa zvekuyedzwa: kuyedza voltage 85KV, wave musoro nguva T1 = 1.2 ± 30%, nguva yekucheka TC = 2 kusvika 6us
Kushanda mumunda: kushandisa maviri-nhanho voltage kubuda
Pane-saiti wave modulation:
Wave musoro kuramba: Level 1 75Ω, Level 2 500Ω (2 1KΩ in parallel)
Wave muswe kuramba: 1st nhanho 45Ω, 2nd nhanho 45Ω
Kuedza kushanda uye waveform:
Mushure meiyi mutsara wekudzidziswa, mutengi ane kunzwisisa kwakadzama kweseti yese yemidziyo, izvo zvinoita kuti mutengi ave nechivimbo mukushanda chaiko!
