CD型操作机构合闸控制电路的改进设计

CD-type Operating Mechanism Closing the Control Circuit Improved Design

针对原有CD型电磁操作机构在合闸时由于机构传动、电源电力、电路控制回路转换等原因而容易发生合闸线圈烧损的故障,对原合闸控制电路进行改进设计,此设计增加了简单、可行的保护电路,以防止此类故障的发生。

The electromagnetic operation of the original CD when closing from institutional agencies in the drive, power supply power, control loop converter circuit for reasons such as fault-prone closing coil burning on the original closing control circuit for improved design, this design increases a simple, workable protection circuit to prevent such failures from occurring.
