基于模块化的继电保护操作板测试仪

研制了一种基于模块化的继电保护操作板测试仪,该测试仪由操作板端口输入模块、检测电源输入模块、继电器接点转接模块和发光二极管判断模块组成。4个模块构成2个回路:检测电源回路和继电器接点动作判断回路。直流检测电源利用波段开关选择端子输入到操作板的继电器线圈回路,继电器的接点动作利用发光二极管的光信号显示。详细地介绍了每个模块的结构和功能,以及测试仪的操作步骤。现场试验表明,操作板测试仪能安全、高效地检验继电保护操作板继电器的继电特性。

Modularized tester for relay protection operating board

A modularized tester for the operating board of relay protection is developed.It consists of four modules:board port inputting module,test power supply inputting module,relay connecting module and LED testing module,which compose two circuits:power supply testing circuit and relay action detecting circuit.The DC testing power supply is fed into the relay coil of operating board via its terminals selected by the tap switch and the relay action is indicated by LED.The structure and function of each module are explained in details,as well as the operating steps of tester.Field test shows that the tester checks the performance of relays protection operating boards safely and efficiently.
