摘要
受测试设备输出容量局限性的影响,目前电力系统中的一些大电容量电气设备(如发电机、电力电缆等)的现场介质损耗测试非常困难。笔者研制的介质损耗测试装置可实现大电容高电压设备的现场介质损耗和电容量测试,最大电容量测试达到2.5μF。整套装置具有运输方便、抗干扰性能强、自动化程度高、测试数据准确、重复性好的特点,已成功应用于现场电力电缆以及发电机绕组介质损耗的测试。
As the limitations of the test device output capacity ,it's difficult to test the dielectric loss of largecapacity equipments such as generators,power cables on site currently. This paper shows a dielectric loss and capacitance testing device working on high-voltage and large-capacity electric equipments on site which can measure capacitance up to 2.5 μF. And it has many advantages such as convenient transport,anti-jamming performance, high degree of automation, accurate testing and reproducibility. It has been successfully used to test dielectric loss of power cables and generator windings in the field.
