| 摘要: |
| 针对高压断路器控制及信号回路二次接线较复杂的情况,改进控制方法,利用可编程逻辑控制器PLC(Programmable Logic Controller)实现对其控制。以单相高压真空断路器为例,改进断路器二次接线,设计了控制程序,实现断路器的分、合闸操作及正常信号的显示,以及自动跳闸后的事故信号动作显示,并实现控制电路的闭锁要求。采用PLC控制,元件数量及种类减少,简化了二次接线,故障查找及修改二次接线容易,同时提高了控制的可靠性,简化了操动机构。 |

| Abstract: |
| To simplify the secondary wiring and control of high-voltage circuit breaker,an improved control scheme based on PLC(Programmable Logic Controller) is presented.With the single phase high-voltage vacuum circuit breaker as an example,the secondary wiring is modified,and its control program is designed to realize the on-off switching control of circuit breaker,signal display during normal operation and after automatic trip and control circuit blocking.The application of PLC decreases the number and type of elements,simplifies the secondary wiring,makes the trouble shooting and wiring modification easy,reduces the control mechanism and enhances the control reliability. |
