摘要
结合实际地铁项目,对空气压缩机的转换供电控制电路进行了介绍,针对原型电路存在的安全隐患,提出了3个改进方案。对各改进方案的电路及控制逻辑做了分析和比较,最终确定了远程输入输出模块(RIOM)常闭型触点串联冗余改进方案为最为安全、可靠的空压机转换供电电路方案。
Based on actual metro projects, the converting power supply circuit of air compressor is introduced. According to the hidden problems existed in the prototype circuit, 3 improved solutions are put forward, their circuits and control logics are analyzed and compared. In the end, the most reliable and safe solution that adopts the air com- pressor converting power supply circuit is confirmed.
