摘　　要：特高压直流换流站电力输送容量大,电压、电流等级高,对电力设备之间的连接接头阻抗控制值要求较高,如果接头阻抗较高,在通过大电流时就会造成严重发热。分析特高压直流换流站接头发热原因,并提出防止接头发热的相关治理措施。UHV DC converter station has large power transmission capacity and high voltage and current level.The impedance control value of the connection joint between the electric power equipment is higher.If the joint impedance is high,serious heat is caused by large current.This paper analyzes the cause of the heating of the joint of the special DC high voltage converter station.Also,the relevant measures to prevent the heating of the joint are put forward.
