TYDR-A型道岔融雪系统应急控制电路的改进
资料介绍
通过对南昌西高铁站TYDR-A型电加热道岔融雪系统设备应急控制电路使用情况进行分析,指出其存在的不足;经过对控制柜内应急控制电路进行改进,能够有效解决室内交流控制电源（AC220V）无法正常供出时应急控制无效的问题,使得该系统应急控制功能得到了进一步的完善。
To analyze the application of the emergency control circuit of TYDR-A type electricheating switch snow-melting system that installed in Nanchang West high-speed railway station,its shortcomings are pointed out.Through improving the emergency control circuit in the control cabinet,invalid emergency control in the case of indoor220 V AC control power supply failing to output can be effectively avoided.Thus,the emergency control function of the system can be further improved.
