specific Embodiment 1

[0067] Such as figure 1 As shown, the power transmission system includes a first pipe mother 12 and a second pipe mother 13, the first pipe mother 12 and the second pipe mother 13 are arranged at intervals along the left and right directions, and there is a The pipe mother support fittings, the pipe mother support fittings include the flange plate 1, the flange plate 1 is provided with a plurality of fixing bolts 11, the flange plate 1 is fixed on the corresponding fixed foundation through the fixing bolts 11, and the flange plate 1 is also fixed There are support plates 14, the number of support plates 14 is multiple, and the upper ends of the multiple support plates 14 are connected to a pressure equalizing ring 15, and the pressure equalizing ring 15 is used to even out the electric field between the two tube mothers.

[0068] In this embodiment, pipe nut hoops 16 are respectively fixed on the left and right sides of the flange plate 1 , and the two pipe nut hoops 16 respec...

Embodiment 1

[0081] In Embodiment 1, the conductive rod and the flange plate 1 are conductively connected through the flexible wire 6, so that the first tube nut 12 and the flange plate 1 are reliably electrically connected when the conductive rod slides in the guide hole.

[0082] In this example, if Figure 3 to Figure 5 As shown, the upper side of the flange plate 21 is provided with a spring contact finger, the spring contact finger includes a base 30 and a contact finger arm 25, the base 30 is a flange structure, and the circumference of the base 30 is provided with a plurality of fixing holes, the flange plate 21 There are a plurality of threaded holes on the top, and the threaded holes correspond to the fixing holes one by one. Fixing screws 22 are installed in each fixing hole, and the fixing screws 22 are threadedly connected with the threaded holes to fix the base on the flange plate 21. A spring washer 23 and a washer 24 are sheathed on the screw 22 to ensure the stability of th...

specific Embodiment 3

[0087] In Embodiment 1, the conductive rod has a threaded rod section on which a fixing nut 10 is threaded, and the conductive piece 5 of the soft wire 6 is fixed on the conductive rod through the fixing nut 10 threaded on the threaded rod section. In this embodiment, a threaded hole is provided on the conductive rod, and a fixing bolt is threaded in the threaded hole, and the conductive piece of the flexible wire is fixed on the conductive rod through the fixing bolt threaded in the threaded hole.

Abstract

The invention relates to a tubular bus support fitting and a power transmission system. The tubular busbar supporting fitting comprises: a flange plate, wherein a tubular busbar hoop is arranged on the flange plate, and a guide hole is formed in the flange plate; a conducting rod which is assembled in the guide hole in a guiding and sliding manner; an elastic piece which is used for applying elastic acting force to the conducting rod, wherein the elastic acting force faces the tubular bus supported by the tubular bus support fitting, so that the conducting rod slides in the guide hole to keepconductive contact with the tubular bus, the conducting rod is in conductive connection with the flange plate through a spring contact finger, the spring contact finger is arranged at the guide hole,and the center line of the spring contact finger coincides with the center line of the guide hole, or the conducting rod is in conductive connection with the flange plate through the flexible connection, one end of the flexible connection is in conductive connection with the conducting rod, and the other end of the flexible connection is in conductive connection with the flange plate. Because theconducting rod is reliably and conductively connected with the flange plate through the flexible connection or the spring contact finger, the equipotential reliable connection of the tubular bus and the flange plate is realized.

Description

technical field [0001] The invention relates to a tube mother support fitting and a power transmission system. Background technique [0002] Tube nut support fittings are mainly used for supporting tube nuts of transmission lines. Existing tube nut support fittings are mainly divided into fixed type tube nut support fittings and sliding type tube nut support fittings. The two kinds of pipe nut supporting fittings are composed of a base and a hoop set on the base. The difference is that: the inner diameter of the hoop of the fixed pipe nut supporting fitting matches the outer diameter of the pipe nut to clamp and fix the pipe nut; The inner diameter of the hoop of the sliding type pipe nut support fitting is slightly larger than the outer diameter of the pipe nut. Under the action of thermal expansion and contraction, the pipe nut can slide in the hoop. For the sliding type tube nut supporting fittings, during the sliding process of the tube nut in the hoop, it will cause po...
