A New Test Method for Anti-Jump Function of High Voltage Circuit Breaker

Zhu Shen-xiang，Sun Gao，Wang Zhen

[Abstract]With the deepening of everyone’s understanding of the anti-jump principle， the verification of the antijump function in the process of infrastructure construction and maintenance has been gradually emphasized. Due to the different requirements and design principles for the anti-jump circuit countermeasures in different periods， the actual use of the on-site anti-jump function is varied. The article focuses on the principle of the anti-jump function of “divided position anti-jump” which plays a vital role in the hand-closing and coincident faults of the circuit breaker， and proposes a specific rectification plan and a perfect field test method.

防跳跃回路在我国高压断路器（开关）控制回路中应用相当广泛，防跳功能实现方式主要有两种，一是靠保护操作箱中TBJ继电器实现，二是靠断路器本体机构箱的防跳继电器实现。（剩余3999字）
