摘要
Abstract
The 3AQ type circuit-breakers are widely used in electric power system. However, nitrogen leakage signal is the most frequent fault signal for this type of circuit-breaker due to its hydraulic operating mechanism. In order to enhance power supply reliability, this paper analyzes both electric location and physical location of the fault, and gives the treatment methods for the two aspects. The treatment methods are verified by three practical fault diagnoses.关键词
