摘要
传统电子式高压互感器设备负载温度故障预警模型检测电子节点温度和等效电阻比时,检测结果准确性差。为此构建了一种新的电子式高压互感器设备负载温度故障预警模型,通过等效电阻法计算出电子式高压互感器设备工作时的热点温度,建立高压互感器设备负载温度故障预警模型,比较测试出的热点温度和标准的高压互感器的热点温度,判断故障类型,实现预警通知。为检测模型效果,设定对比实验,结果表明,构建的预警模型能够精准地检测出检测电子节点温度和等效电阻比,达到预警效果。
When the load temperature fault early warning model of traditional electronic high-voltage transformer detects the temperature of electronic node and the equivalent resistance ratio,the accuracy of detection results is poor.In this paper,a new early warning model of load temperature fault of electronic high-voltage transformer is constructed,the hot spot temperature of electronic high-voltage transformer is calculated by equivalent resistance method,the early warning model of load temperature fault of high-voltage transformer is established,the hot spot temperature measured is compared with the hot spot temperature of standard high-voltage transformer,the fault type is judged,and the early warning is realized Know.In order to detect the effect of the model,a comparative experiment is set up.The results show that the early-warning model can accurately detect the temperature and the equivalent resistance ratio of the detected electronic nodes,and achieve the early-warning effect.
