Embodiment Construction

[0015] from figure 1 It can be seen that the connection fittings in the present invention are all composed of pipe busbar clamps, jumper pipe clamps and key components, wherein the rigid sliding fittings and universal joint fittings have the same clamp structure at both ends, and are all disc-type clamps. The clamps of the fastening and telescopic diversion metal fittings respectively clamp the pipe busbar body and the pipe busbar jumper pipe body. There are small holes on the edge extension of the fixture, and the small holes are used to install flexible wires.

[0016] figure 2 It is a telescopic diversion fitting, and its components are four fixtures with the same structure and six flexible wires. The fixtures are all semicircular structures with corresponding bolt holes on them. The semicircular structures are butted in pairs and sleeved on the busbar , fastened by screws.

Abstract

The invention discloses novel combined connection fittings used for tubular buses and a wire jumper tube and a connection method of the novel combined connection fittings. The connection fittings for the tubular buses and the wire jumper tube include the telescopic diversion fittings, the rigid sliding fitting and the universal joint fitting. According to the connection method of the novel combined connection fittings, the two tubular buses are connected through the wire jumper tube and a wire jumper tube combined fitting, wherein one end of the wire jumper tube 4 and the tubular bus 5 are provided with the rigid sliding fitting 2 and one telescopic diversion fitting 1, and the universal joint fitting 3 and the other telescopic diversion fitting 1 are arranged at the other end of the wire jumper pipe 4. In this way, the deflection of the tubular buses is greatly reduced, installation is convenient, the height of a tower is reduced, and investment is saved.

Description

technical field [0001] The invention relates to the installation of a jumper tube for a busbar in the field of power transmission and distribution, in particular to a new connection method for a jumper tube for a busbar and a matching combined connection fitting. Background technique [0002] The installation of tubular busbars has support type and suspension type. The jumper connection between the spans of the tubular busbars is generally made of T-joint fittings and soft wires. Since the wires have sag and the over-current capacity of the wires is limited, In addition, it is affected by the wind and swings greatly, which affects the safe operation of the substation, and it is difficult to install, high in cost, and unsightly. Contents of the invention [0003] The purpose of the present invention is to provide a new type of connecting fitting for jumper tubes which is easy to install and can reduce the sag of the tube busbar. Its implementation is as follows: [0004] ...
