一起SB6型断路器低气压报警事故分析处理过程

Analysis and Process of a Low Pressure Alarm Accident of SB6 Type Circuit Breaker

SB6型断路器的结构原理较为独特,具有高、低压两个气室,且操动机构在本体内,使其安装、调试和维护与其它SF6断路器有所不同。为了更好的了解和熟悉该类型断路器,介绍了一起SB6型开关低气压报警事故分析处理过程,给出SB6断路器在检修中分析方法及处理思路。对该类断路器正确的维护提供很好的参考。

The structural principle of SB6 circuit breaker is very speical and has high and low pressure air chambers, and the actuating mechanism is in its housing. Its in stallation, debugging and maintenance are different from other SF6 circuit breakers. In order to understand and master the circuit breaker, an analysis and process of low pressure alarm ac- cident of SB6 switch is presented. The analysis method and process of SB6 circuit breaker maintenance are given. It will afford good reference for the circuit breaker maintenance.
