Malfunction Analysis of a 500 kV Transformer Gas Relay with Countermeasure
摘要
Abstract
For a malfunction of heavy gas protection of a 500 kV transformer, the structure and working principle of the gas relay are described. Investigation and calculation indicate that this malfunction of the gas relay is due to blockage of the dehydrating breather, negative pressure in the oil tank, and improper structure of the gas collection box. Corresponding emergency measure is put forward, and modification of the gas box is suggested.关键词
