Abstract:
35kV overhead transmission line is an important part of regional power grid, and the heat defect of drainage line is common. For a long time, due to the small gap between the equipment and the high safety risk and difficulty in implementing the hot and charged treatment of the drainage line, the improvement of power supply reliability has been seriously restricted. Based on the analysis of the necessity of live working on the heat defect of the drainage line of 35kV overhead transmission line, this paper proposes to use the indirect operation method to install a shunt line to reduce the temperature of the hot spot, and describes in detail the operation principle, the structure of the conductor shunt connector, the installation method and operation process of the shunt. Through a large number of practice, it has been proved that this operation method has the advantages of less capital investment, high operation efficiency, safety and reliability, and can quickly solve the problem of 35kV overhead transmission line drainage line heating, and effectively promote the safe development of live line operation.
