Abstract

Converter valve surge arrester is one of the key overvoltage protection devices for ±800 kV UHVDC converter station and its technology research and product development is an important task to realize the localization of UHVDC equipment. Based on the introduction of operating principle of dual 12 pulse converter valves

the steady-state stress and the transient stress of converter valve arresters are analyzed. The rules to develop the main technical parameters of valve arresters are proposed. The key technologies of ±800 kV UHVDC converter valve surge arresters are deeply studied with Xiangjiaba-Shanghai UHVDC project. Finally the author points out that: to choose the appropriate chargeability and thermal structure is the key technical problem when complete design of valve surge arrester must be considered. The paper also puts forward a column parallel resistance more technology

can provide arrester with high specific energy absorption capacity of technical support.
