断路器操作回路设计改进

Design Improvement of Breaker Operating Circuit

介绍了断路器操作回路的一种设计改进方法,该操作回路适用于110 kV以下电力断路器的操作,具有防跳、分合保持、位置信号、操作回路断线监视等功能。与原有操作回路相比,节约了元件数量,简化了电路设计,可嵌入6 kV/10 kV、35 kV断路器成套设备就地安装的继电保护和安全自动装置中。同时该设计借助自动设备的智能采集和逻辑判断功能,可实现对断路器分、合操作过程的在线监测。

A new switching circuit design method was introduced, the operating circuit was applicable to 110 kV and below power breaker operation, with anti-jump, points maintained, position signal operation circuit disconnection monitoring functions, compared with the original operating circuit, which could save component count, simplify the circuit designing, embed 6 kV/10 kV, 35 kV switch equipment installed on the spot of the relaying protection and security automatic equipment, also based on the automatic equipment of intelligent acquisition and logic functions, the new design scheme could realize the switching process of transparent, had the online monitoring function to the circuit breaker in operation process of tripping and closing.
