摘　　要：高压并联电容器极对壳绝缘水平是保证其在电网安全运行的重要参数。对隐箔引线片、露箔无内熔丝、露箔有内熔丝等几种电极结构的10kV全膜电容器进行极对壳耐压试验,测量局部放电特征并对油中气体进行气相色谱分析,分析不同电极结构对电容器极对壳绝缘特性的影响,为电容器制造厂家和电力系统的绝缘监督提供一定的参考依据。The Insulation level between poles and enclosure is important for high voltage shunt capacitors to increase the operation reliability. For various electrode structures of capacitors popularly used, such as lead pole type, exposed foil type with internal fuse or not, withstand voltage tests across poles to enclosure are made. The characteristic of partial discharge and the gas chromatography are measured in order to analyze the interrelation of electrode structures and insulation characteristic between poles and enclosure, which can provide references to manufacturers and users.
