摘要
特高压直流试验基地中的电晕笼,是世界上最大的2厢式、悬链形电晕笼,长70 m,宽22 m,高15m。电晕笼由内外2层金属网组成,内层是测量网,外层是屏蔽网,内外2层网之间用绝缘子保持绝缘。电晕笼沿长度方向设计成悬链形,两端设置塔架悬挂导线,导线从电晕笼的内层测量网中穿过。既可进行单极试验,也可进行双极试验,试验电压能够达到±1200kV。
The UHV DC testingsitehastheworld＇s largest two compartment,catenary-shaped coronacage,with a size of 70m （L）×22m （W）×15m （H）. It consists of 2 layers of metal nets, the inner layer being a measuring net and the outer one shielding net, between them are insulators. The corona cage is designed to be catenary shape along its length with suspension conductors on both ends that go through the inner measuring net. Both single pole and dual pole tests can be performed with maximum testing voltage of ± 1200 kV.
