Keeb kwm ntawm Composite Insulators

Nyob rau xyoo 1980, nrog kev txhawb nqa los ntawm Lub Tebchaws Xya Tsib -Xyoo Plan, Lub Tsev Haujlwm ntawm Hydraulic thiab Hydroelectric Engineering thiab lwm lub koom haum tau pib tshawb fawb thiab tsim cov khoom sib xyaw ua ke. Ob lub tsev kawm ntawv tau siv siab -kub vulcanized silicone roj hmab rau cov khoom siv, tab sis siv cov kev sib txawv ntawm kev sib txuas ntawm cov fittings thiab epoxy fiberglass core rods. Lub tsev kawm ntawv tau siv cov qauv sab hauv, thaum lub koom haum ntawm Hydraulic thiab Hydroelectric Engineering siv cov qauv sab nrauv. Kev ua tiav thev naus laus zis ntawm ob lub tsev kawm tau raug xa mus rau cov tuam txhab lag luam thiab hloov mus ua cov khoom tsim tau.

Thaum xub thawj, lub chaw ua haujlwm fais fab muaj kev tsis txaus siab txog kev ua haujlwm ntawm cov khoom siv hluav taws xob sib xyaw thiab tau ceev faj heev txog kab hluav taws xob- kev sib txuas, tsuas yog ua nyob - kab kev sim ntawm qee qhov ntsuas me me ntawm cov kab tsis tseem ceeb nrog cov qib voltage qis dua 110 kV. Xyoo 1990, ib qho loj - nplai thiab kev sib tsoo loj heev tshwm sim hauv North China. Cov khoom siv hluav taws xob sib xyaw ua ke tau sim ua kom pom kev ua haujlwm zoo heev, uas tau zoo - tau txais los ntawm lub zog ua haujlwm. Ntau lub tuam tsev tau nquag siv cov thev naus laus zis tshiab no, nthuav dav cov nplai thiab cov kev ua haujlwm ntawm kev sim ua haujlwm, zoo heev txhim kho lub flashover tsis kam ntawm kev sib kis thiab kev faib cov kab thiab txo cov kev ua haujlwm ntawm cov kab tu, yog li tau txais kev muaj koob meej ntawm cov chaw ua haujlwm fais fab. Tom qab ob peb xyoos ntawm kev ua haujlwm thiab kev soj ntsuam, cov tub ceev xwm lub hwj chim tau lees paub cov khoom siv hluav taws xob sib xyaw ua cov cuab yeej tshiab los tiv thaiv flashover thiab tau pib siv lawv hauv qhov hluav taws xob siab tshaj 110kV.
