Ultra-high voltage transmission line clamp replacing tool

Abstract

The invention provides an ultra-high voltage transmission line clamp replacing tool. The tool comprises a connecting plate used for being fixedly connected with a yoke plate, cross beams extending outof the left side and the right side of the connecting plate are arranged on the connecting plate. The connecting plate and the cross beam are in a vertical position relationship. The tail ends of thecross beams on the left side and the right side of the connecting plate are rotationally connected with two rotating nuts respectively. The rotating nuts are in threaded connection with lead screws,the lead screws are parallel to the connecting plate, sleeves are arranged at one ends of the lead screws, for the two lead screws located on the same side of the connecting plate, the ends, providedwith the sleeves, of the two lead screws are opposite in the vertical direction, and the directions of all the sleeves are approximately perpendicular to the connecting plate. The device can improve the stress of the branch wire in the operation of replacing the wire clamp, and protects the branch wire from being damaged.

Description

Technical field [0001] The invention relates to the technical field of tools for power transmission equipment, in particular to a tool for replacing ultra-high voltage transmission line clamps. Background technique [0002] The ultra-high voltage transmission line is an important part of the modern power grid system, and it is an inevitable requirement for the growth of power generation capacity and power load, and the extension of power transmission distance. Ultra-high voltage transmission is one of the important signs of the development level of the power industry. With the widespread development of electric energy utilization, many countries are building large-capacity hydropower stations, thermal power plants, nuclear power plants, and power stations, and power resources are often far away from load centers. Only by using ultra-high voltage transmission can the transmission task be achieved effectively and economically. Ultra-high voltage transmission can increase transmiss...

Problems solved by technology

Usually, to deal with such defects, it is necessary to adopt the combined operation method of "suspension device + multi-split wire lifting hook". The decisive factor, if a problem occurs, it will lead to the serious consequences of the discharge of the wire to the tower or the loss of the wire

[0005] In the prior art, there have been clamp replacement tools fixed on the connecting plate, such as related tools with publication numbers CN208299324U and CN107706822A, but when the existing tools replace the clamps, the weight of the lifted sub-conductor is transmitted to the On other sub-conductors, but especially for even-numbered sub-conductors, such as 4-split conductors, the sub-conductor with the largest load is the one on the same side as the lifted sub-conductor, and the existing large number of connecting boards are not designed. Considering the relevant stress conditions, the area of ​​action between it and the sub-conductor is limited, which will cause the force on the corresponding load-bearing sub-conductor to be too concentrated, which may damage the sub-conductor and reduce the life of the sub-conductor.
