配电网一二次融合开关二次部分的可靠性测试
|
摘要
通过搭建高电压温度环境箱和雷电压冲击测试平台模拟一次设备工况环境,从温度和电磁干扰两个方面进行二次部分的试验测试和数据分析。试验发现温度会导致二次部分功耗、电压、电流等电气量发生明显变化,雷电冲击造成高于1 kV的干扰电压会导致二次部分出现误动和死机等故障现象。测试结果可为配电网一二次融合成套设备的性能检测及评估提供参考依据。
The working conditions of primary equipment are simulated by setting up a high voltage temperature environment box and a lightning voltage impulse test platform. The test and data analysis of the second part are carried out from two aspects of temperature and electromagnetic interference. It is found that temperature will cause obvious changes in power consumption, voltage, current and other electrical quantities of the secondary part. The disturbance voltage above 1 kV caused by lightning impulse will lead to malfunction and shutdown of the secondary part. The test results can provide a reference for the performance testing and evaluation of the primary and secondary integration equipment of power grid.
