【摘要】 该文阐述了绝缘子污闪机理及运行状态与泄漏电流的关系。利用泄漏电流脉冲幅值及各个幅值段的脉冲个数,结合温度对绝缘子运行状态进行判断,并在此基础上介绍了通过短消息实现数据传输的绝缘子泄漏电流在线监测系统。试验表明,这种设计方案具有结构简单、操作方便、测量准确可靠的特点。更多还原

【Abstract】 The paper expounds the mechanism of insulator contamination flashover and the relationship between its running status and leak current.Combining the factors of temperature and humidity,the running status of insulators is estimated based on the amplitude and statistic number of pulse current in different phases.And it is concerned with an on-line monitoring system by using SMS to send parameters of insulators.The results show that the project has the characteristic of simple structure,easy operating and reliable measurement.更多还原
