Intelligent Detecting System Design Based on High Voltage Circuit Breakers of Function Integration

针对高压断路器的预防性试验项目繁多,为了减少试验人员的登高及接线次数、提高现场工作效率,本文综合考虑高压断路器各项电气试验的试验要求后,利用各试验项目的可归并性,将断路器的介质损耗、电容值测量、回路电阻、分合闸线圈直阻、机械特性、合闸电阻及投入时间、辅助及控制回路绝缘电阻及交流耐压等检测项目功能集成在一套系统上,在试验前配置所需完成的检测项目及相关参数后,实现全程一次接线、拆线操作,自动逐项完成全部项目检测、测试数据采集及智能化分析。

Since there are various preventive test items for high voltage circuit breaker,in this paper,a function-integrated hardware is put forward to reduce the height and wiring times of the test personnel and improve the field work efficiency.Firstly,we comprehensively analyze the electrical test requirements for high voltage circuit breaker.Then we integrate multiple detection projects into one system,taking advantage of the fact that each test project can be merged.These test projects include tests of dielectric loss of circuit breaker,capacitance value,circuit resistance,direct resistance of switching coil,mechanical characteristic,closing resistance and closing time as well as insulation resistance and AC withstand voltage of auxiliary control circuit.Next,we configure the required detection items and relevant parameters before the test.Finally,we complete the whole process,which requires connection and disconnection for only once and will automatically finish all project detection,test data collection and intelligent analysis item by item.
