摘要
在高岭换流站内交流滤波器场区,交流滤波器组有HP3、SC、12/24三种布置形式,在12/24布置形式中,每个电容器塔由电容器单元、电容器框架、支柱绝缘子、紧固件、连线及接线夹组成。电容器单元为户外、双套管卧式安装形式,安装在框架中,框架对地用支柱绝缘子支撑,以满足绝缘的要求。为了防止产生电晕,在处于高压端的框架周围,装设防晕环,在高压端进线处设防晕装置,塔间连接采用铝合金管母线。
There are three configurations of AC filter banks, namely HP3, SC, and 12/24, in AC filter yard of Gaoling converter station. In 12/24 configuration, each capacitor tower consists of capacitor unit, capacitor frame, post insulator, fasteners, connecting cables, and connecting clamps. The outdoor, dual-sleeve, horizontal capacitor unit is installed within a frame, which is supported by post insulators to meet insulation requirements. To prevent corona from occurring, corona rings are installed around HV side of the frame. Corona prevention device is equipped on the HV side line-in. Aluminum-alloy bus-bar is used to connect between two towers.
