| 摘 要： | 气体绝缘输电线路(GIL)是高电压、大电流、长距离的电力传输设备,国内外已有近30年的运行经验。它具有电能损耗小、可靠性高、送电容量大、运行维护工作量小、使用寿命(50年)长、对环境无影响等优点。结合拉西瓦水电站的装机容量大、电压等级高、地形复杂、海拔高及高压出线无法采用架空线等特点,对电站出线段采用750kVGIL的必要性和合理性加以介绍,并提出下一阶段设计中应考虑和研究的问题。

| Abstract: | The GIL is a transmission equipment for the transmission of high voltage and heavy current over long distance.Based on about30years of operation experience,GIL has main advantages,such as low resistive loss,high reliability,large power transmission capacity,low maintenance cost,long life in service(about50years)and no effect on the surroundings,etc..Laxiwa is a hydroelectric power station with special conditions of large generating power capacity,high transmission voltage,complicated landform,high altitude,unable to use overhead line for750kV outgoing line,and so on.This paper describes the rationality for using GIL on the plant,and puts forward the questions that need to be considered on next design stage. |
