摘要
为满足生产和检测的需要,开发了以触摸屏、PLC和恒流源为核心部件的塑壳断路器(MCCB)瞬时特性检测系统。该检测系统能根据测试产品,自动控制恒流源输出测试电流进行瞬时特性试验,并判断产品测试结果。
In order to meet the needs of production and testing, a moulded case circuit breaker（MUB） instantaneous characteristics detection system based on touch screen, PLC and constant current source was developed. According to test product, the system can automatically control current output of constant current source, execut current instantaneous characteristic test and determine product test results.
