Abstract
Aiming at the rapid change of tower tilt rate and dynamic instability of a±500 kV DC line tower caused by slope sliping,a method of dismantling unstable tower with"simultaneous removal of conductors at two ends and two poles"is proposed.By maintaining the dynamic balance of the loads on both sides of the unstable tower during the demolition of the grounding wire,the safety of the tower and the workers can be effectively guaranteed,the expansion of the fault range can be prevented,and the impact on the highway traffic and the surrounding residents can be reduced.The force calculation of the overall collapse process of the tension tower is carried out,which solves the problems such as the reverse of the jump gear and the out of control of the tower collapse direction caused by the insufficient tension of the grinding force.It is of great engineering significance to protect the surrounding towers and equipment.关键词
