High Voltage 100kn Disc Suspension Yakaomeswa Girazi Insulator U100B Featured Image

Tsanangudzo Pfupi

Girazi insulator mudziyo unoshandiswa kutsigira conductor nekuiisa mukati.Yakagadzirwa negirazi.Parizvino, tempered glass insulator ndiyo inonyanya kushandiswa munzira.Iyo inowanzo gadzirwa negirazi uye porcelain, uye ndicho chimwe chezvinhu zvakakosha zveyakakwira-voltage transmission line.Kuita kwayo kunobata zvakananga kuchengetedzwa kwekushanda kweiyo yose yekufambisa mutsara.Magirazi insulators anoshandiswa zvakanyanya nekuda kwehunhu hwe zero kukosha kwekuzvityora uye nyore kugadzirisa.

Kuita kwegirazi insulator

1.1 Hunhu hwezvikamu
Hunhu hwe disc-mhando kuturika insulator zvinhu zvichaenderana neGB/T 7253.
1.2 Dimensional Kutsauka
Zviyero zvevayedzo insulators zvinoenderana neanoenderana madhirowa, uchinyatso tarisa kune chero zviyero zvine zvakakosha zveveruzhinji (semuenzaniso, yakatarwa chimiro urefu) uye ruzivo rune chekuita nekuchinjika (semuenzaniso, zviyero zvekubatanidza sezvakatsanangurwa muGB/T 4056).
A) Kunze kwekunge kwakabvumiranwa neimwe nzira, pazviyero zvese zvisina kucherechedzwa nekutsauka kwacho, kutsauka kunotevera (d ndiyo chiyero chekuongorora, mumayuniti; Mm);
Ivhu (0.04d+1.5) mm, apo D ≤300mm uye kureba kwese creepage kure;± (0.025d +6) mm, apo D > 300mm;
Kutsauka kwapihwa pamusoro kunoshanda kunyangwe chinhambwe checreepage chatsanangurwa semutengo wezita wepadiki diki.
B) Kutsauka kwehurefu hwechimiro chezvidziviriro ndeye ± 0.024nh (n inomiririra matanhatu insulators).Kwe 330kV uye pamusoro pekushandisa zvachose
Edge, iyo yekumisikidza kureba kutsauka kwe6 insulator tambo haifaniri kudarika ± 19mm.C) Shanduko yegeji yeaxial yekuyera mudziyo ichaiswa pa 4% yezita rezita re insulator;
Iyo geji yekuchinja yeradial yekuyeresa mudziyo inoiswa pa 3% yezita re insulator dhayamita.
1.3 Insulators
Kutaridzika kwemhando yeporcelain kunoenderana nezviga zveChitsauko 28 cheGBT 772-2005 (1.3) uye GBT 1001.1-2003 (GBT 1001.1-2003).Pamusoro peiyo porcelain insulator ichave isina warps, maburi ejecha, mabhuru, mabumps, zvinhu zvekunze uye zvimwe zvirema.
Kutaridzika kwemhando yezvikamu zvegirazi kunoenderana neJB/T 9678-1999 Chitsauko 4 uye GB/T1001.1 -- 2003 Chitsauko 28. Insulator girazi harizove nekutsemuka, seam, mapupu emhepo, tsvina nezvimwe zvinokanganisa, uye zvichave zvisina yakapfava zvakafanana pamusoro payo.Magirazi ese ari pachena anofanirwa kuve anoparadzira chiedza.
1.4 Chivharo chesimbi uye tsoka yesimbi
Iron caps of insulators ichaenderana neJB/T 8178. Insulator pot tsoka ichaenderana neJB/T 9677. Caps netsoka hazvizoitwe nekubatanidza, welding, cold crimping kana chero imwe nzira inosanganisira zvinopfuura chimwe chinhu.
