±800kV特高压直流换流站阀厅金具的结构特点
|
摘要
±800 kV特高压直流换流站阀厅工程设计中,换流阀与换流变压器及穿墙套管之间采用管型母线连接方式,设备连接需采用特殊的管型母线连接金具。笔者通过对向家坝—上海、锦屏—苏南±800 kV特高压直流输电工程换流站阀厅金具的结构介绍,阐述了阀厅金具的整体结构特点,分析了金具的载流量和耐热性、防电晕特性、机械强度的可靠性、外形尺寸以及连接形式等要求。通过实例介绍了5种常用的阀厅金具的结构细节及特点,为哈密南—郑州及溪洛渡—浙江等特高压换流站阀厅金具设计提供参考和借鉴。
During the design stage of valve hall project in the ±800 kV ultra-high voltage direct current(UHVDC) convertor station,the connections among convertor valve,convertor transformer and the wall bushings have to use the tubular busbar connection type,whereas,the devices connections need the special tubular busbar link fitting.In this paper,taking the valve hall fittings in the Xiangjiaba-Shanghai and Jinping-Sunan ±800 kV UHVDC convertor station as example,the overall structure characteristics of the valve hall hardware fittings are discussed including the requirements of hardware fitting such as the carrying capacity and heat resistance,the anti-corona characteristics,the reliability of mechanical strength,dimensions and shapes,and the connection types.At last,the structure details and characteristics of five often-used valve hall fittings are introduced in the examples.They are useful and can be referred in the design of valve hall fittings for the new UHVDC convert stations such as HaminanZhengzhou,and Xiluodu-Zhejiang etc.
