交流特高压避雷器的带电考核与工程投运
摘要
1 000 kV交流特高压瓷套型金属氧化物避雷器(1 000 kV AC ultra high voltage porcelain-housed metaloxide surge arrester
The successful development of the 1 000 kV AC ultra high voltage porcelain-housed metal oxide surge arrester(UHV MOA) is one of the most important achievements in arrester area.Before the completion of the China UHV AC demonstration project
UHV MOA has not been used for long-term live operation at home and abroad.The requirements of performance
the test methods
as well as the operation parameters of the UHV MOA are different from the 750 kV and below MOA’s
for its 4-columns parallel structure and the height of over 10 meters.The long-term live test is an important test
which verifies whether the MOA design meet all the requirements in specifications.This paper details the long-term live test and the engineering operation of the UHV MOA in UHV AC demonstration project
raised some problems and put forward some reasonable suggestions.
