Abstract

The invention provides a replacement tool for ultra-high voltage transmission line clamps, which includes a connecting plate for fixed connection with the connecting plate, and beams protruding from the left and right sides of the connecting plate are arranged on the connecting plate, and the connecting plate The plate and the crossbeam are in a vertical position relationship. The ends of the crossbeam on the left and right sides of the connecting plate are respectively rotated and connected with two rotating nuts. One end of the screw is provided with a sleeve. For the two screw on the same side of the connecting plate, the ends of the two sleeves are in opposite directions. The orientation of all the sleeves is generally perpendicular to the connecting plate. plate. The device can improve the stress of the sub-conductors and protect the sub-conductors from damage during the operation of replacing the clamps.

Description

technical field

[0001] The invention relates to the technical field of tools for power transmission equipment, in particular to a replacement tool for ultra-high voltage transmission line clips. Background technique

[0002] EHV transmission lines are an important part of the modern power grid system, and are an inevitable requirement for the increase of power generation capacity and power load, and the extension of transmission distance. EHV transmission is one of the important symbols of the development level of the electric power industry. With the extensive development of electric energy utilization, many countries are building large-capacity hydropower plants, thermal power plants, nuclear power plants, and power plant groups, and the power resources are often far away from the load center. Only by using ultra-high voltage power transmission can the power transmission task be effectively and economically realized. EHV transmission can increase the transmission capacity...
