110kV瓦-隆线脱冰跳跃故障原因分析及治理

Cause analysis and treatment on the conductor sleeting jump fault in 110 kV Wating-Longde power transmissin line

针对110 kV瓦-隆线脱冰跳跃故障进行原因和特性分析,分别计算了(45～46)号塔,(46～47)号塔2个档段脱冰跳跃引起的档中最大振幅,在此基础上,借鉴国网公司治理架空线舞动的经验,设计了相间间隔棒的布置位置,给出了采用相间间隔棒进行治理的措施。运行情况表明:该治理措施取得了预期的效果。

Aiming at the conductor sleeting jump fault in 110 kV Wating-Longde power transmissin line, analyzes causes and characteristics of the fault, calculates the maximum oscillation amplitude of line between No. 45 and No. 46 tower and between No.46 and No.47 tower caused by the conductor sleeting jump, references the experience of the state grid treated the oscillation of overhead line, designs the collocation place of phase space stick, puts forward the treatment measures of using the phase space stick. The operation result shows that the treatment measures obtain the expected effect.
