PIC单片机控制的漏电保护器测试系统

摘要

介绍了一种漏电保护器性能测试系统的软、硬件设计.该系统利用电抗器和电阻器做模拟负载,通过PIC单片机对漏电保护器进行接通操作和分断操作,利用试验装置自动断开.对漏电保护器进行的机械疲劳性能试验,不损坏保护器的使用.%This paper presents the software and hardware design for a leakage circuit breaker test system. This system employs a resistor and an inductor as a load simulator, a PIC single-chip computer to control the connection and disconnection of a leakage circuit breaker. This system can also automatically terminate an experiment. Repetitive mechanical fatigue test shows that a circuit breaker can not be damaged and can work normally.
