信号机灯口电压超标问题分析及解决方案

Cause Analysis and Countermeasure of Over Threshold of Signal Lamp Socket Voltageb

对造成信号机灯口电压超标问题的原因进行了系统分析,并提出了为适应智能电源屏供电实际,通过增加信号隔离变压器解决灯口电压调整问题的解决方法。

In this article, we make an in-depth analysis on cause of the over threshold of the signal lamp socket voltage. Moreover , in order to adapt to the power supply of the smart power supply panel, we solved the problem of lamp socket voltage adjustment by adding extra signal isolation transformers.
