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
