摘　　要：通过在特高压1 100 kV GIS真型上开展特高频法与传统脉冲电流法测局部放电的比对研究,以及在GIS罐体底部置入异物的方式激发局部放电,确定了两种方法测试值的对应关系。提出了局部放电监测装置在特高压气体绝缘金属封闭开关设备GIS出厂时的试验建议,为确保GIS局部放电监测装置的有效性提供技术参考。项目的成果满足我国超特高压工程的运行急需,可一定程度减小GIS运行事故及现场抢修造成的经济损失。In this paper,comparative research on the UHF method and the pulse current method for partial discharge measurement of 1 100kV GIS was carried out, and the discharge was generated by artificial defect models set in the tank. The relationship of test results contained by the two means above was determined. Advices for test of partial discharge measurement devices is given,which can provide technical reference to GIS partial discharge monitoring system. The achievements above can be applied to the UHV engineering in China, which may reduce the economic losses caused by GIS failures and on-site restoration.
