LW25-126断路器储能及超时信号异常分析与对策

Analysis and Countermeasures of Abnormal Energy Storage and Time-out Signal of LW25-126 Circuit Breaker

虽然SF6断路器在电力系统中被广泛应用,但其也存在一些不足之处。分析了某变电站LW25-126断路器储能及其超时信号异常的原因,提出防范措施和对策,并对其相关回路进行改进。改进保障了设备的安全运行,提高了供电可靠性。

Although SF6 circuit breaker is widely used in power system, it also has some shortcomings. This paper analyzes the cause of abnormal energy storage and time-out signal of LW25-126 circuit breaker in a substation, puts forward preventive measures and countermeasures, and modification of relevant circuits. The improvement ensures the safe operation of the equipment and enhances the reliability of power supply.
