Abstract
简要介绍剩余电流保护功能断路器测试台的系统组成,依据GB14048.2—2008《低压开关设备和控制设备第2部分:断路器》试验标准进行设计,采用调压器与变压器结合使用产生不同等级电压,使用电流传感器进行采样.实验台具有低损耗,精度高,适用范围大等优点,可用于不同等级具有剩余电流保护功能的断路器的检测试验.
Briefly introduced the system composition of residual current circuit-breakers testing bench. The test bench was designed according to GB14048.2-2008,electric voltage regulator and transformer were combined for the device to generate different voltage,sampling was performed using current sensor. The test bench has the advantages of low-loss,high accuracy and wide application range. It can be widely used in the test of residual current circuit-breakers.
