信号控制电源传输分析

本文通过两个故障实例，分析了条件电源的依赖性、独立性和隐蔽性特征，并有针对性地提出电阻法和电压法两种检查方法，消除条件电源混线；对电源接地中直接接地和条件接地的不同表现方式进行了分析，尤其对公共回线控制电路中条件接地的查找和处理，提出了更为简便、快捷的方法。

Analysis on Transmission of Power Supply Used for Signaling Control

This paper analyzes the features of power supply including its independence,dependence and crypticity by two examples and proposes two measurement methods suchas resistance measurement and voltage measurement to eliminate power wiring mixture. It also analyzes the different aspects between direct earthing and conditional earthing and puts forward a faster and more convenient method for finding out and dealing with the conditional earthing in control circuit with public loop.
