Study on 252 kV GIS Partial Discharge Test Simulation Platform Design

GIS(Gas Insulated Switchgear)内部由于绝缘缺陷导致局部放电,严重损害内部器件的绝缘性能,需采取一定的手段和方式对局部放电进行检测。结合国内GIS局部放电的研究成果,综合各种检测方法和电子设计方案,对252 kV GIS局部放电仿真平台进行设计和试验演示。结果证明:该仿真平台设计能够很好地模拟典型的绝缘缺陷以及局部放电过程,同时能够为试验观察和检测提供便捷条件。

GIS （Gas Insulated Switchgear） is a closed type gas insulated switchgear which is widely used in power system because of its small size, strong anti-interference ability and reliability. However, due to its internal insulation defects caused by partial discharge （PD） phenomenon,it seriously damage the insulation performance of the device.It must take a certain means and methods for the detection of partial discharge.The research results of GIS partial discharge in China combined with various detection methods and electronic design, analyzing and completing the design of 252 kV GIS partial discharge simulation platform.The experimental demonstration and the results show that the simulation platform can simulate the typical insulation defects.The partial discharge process can provide convenient conditions for the experimental observation,detection and can achieve the purpose of the platform design.
