摘 要:介绍了微机保护操作箱与断路器机构箱的工作原理。分析比较了微机保护操作箱防跳、断路器机构防跳和微机保护操作箱防跳结合断路器机构防跳在运行工作中的优缺点,建议在控制回路中同时保留微机保护操作箱防跳与断路器机构箱防跳接线,选择远方时采用保护操作箱防跳,就地时采用断路器机构箱防跳,通过彼此间的切换实现优势互补,弥补单独使用某种防跳所带来的缺陷。

Abstract: Introduction was made to the operating principles of microcomputer protection control box (MPCB) and circuit breaker operation box (CBOB). By analyzing and comparing the advantages and disadvantages of the anti-bounce circuits for MPCB and CBOB, this paper recommended that both of the anti-bounce circuits for MPCB and CBOB should be kept in the control loop. The anti-bounce circuit of MPCB was used for remote control, while the anti-bounce circuit of CBOB was used on site. By switching from one to the other, the complementary advantages achieved, and the defects of single anti-bounce are compensated.
Key words: circuit breaker; microcomputer protection; anti-bouncing
