摘 要:介紹了微機保護操作箱與斷路器機構(gòu)箱的工作原理。分析比較了微機保護操作箱防跳、斷路器機構(gòu)防跳和微機保護操作箱防跳結(jié)合斷路器機構(gòu)防跳在運行工作中的優(yōu)缺點,建議在控制回路中同時保留微機保護操作箱防跳與斷路器機構(gòu)箱防跳接線,選擇遠方時采用保護操作箱防跳,就地時采用斷路器機構(gòu)箱防跳,通過彼此間的切換實現(xiàn)優(yōu)勢互補,彌補單獨使用某種防跳所帶來的缺陷。

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
