摘　　要：分析了±500 kV换流站换流阀的结构组成和电气组成,对换流阀的工作原理进行了详细的阐述,并对组件内各元件的作用进行了详细说明,对一个12脉动换流单元的两侧换流站如何与交流系统进行连接给予了阐述。通过各组成结构的具体分析,对换流阀存在隐患和故障的预知、预测起到一定的作用。The structure and electrical components of the thyristor valve for _＋500 kV converter station are analyzed. The working principle of the thyristor valve and the role of each component are discussed. And the connection of the 12-pulse thyristor units on both sides of the converter station to AC power system is described. This study may be helpful to the fault prediction of the thyristor valves.
