Pipe bus suspension fitting

Abstract

The invention relates to a pipe bus suspension fitting. The pipe bus suspension fitting comprises a shielding ball and a support rack, wherein the support rack is arranged in the shielding ball and comprises a support arm, one end of the support arm is fixedly connected with an inner wall of the shielding ball, a hanging structure is arranged on the support rack and is used for hanging a pipe bus,a pipe bus penetrating hole and a suspension penetrating hole are formed in the shielding ball, the pipe bus penetrating hole is used for the pipe bus to penetrate through, the suspension penetratinghole is used for connecting the support rack and a suspension insulator, a connection rod is rotatably assembled onto the support rack, a rotation axis of the connection rod extends along an upward-downward direction, a connection part is arranged at an upper end of the connection rod and is used for connecting the suspension insulator, and a bearing part is arranged at a lower end of the connection rod and is used for supporting the support rack in a matching way so as to support the support rack and the shielding ball. By the pipe bus suspension fitting, the facing direction of the pipe buspenetrating hole in the shielding ball can be flexibly adjusted, so that the penetrating requirement of the pipe bus is adapted, and the pipe bus suspension fitting is convenient to install and is high in installation efficiency.

Description

technical field [0001] The invention relates to a pipe bus bar suspension fitting. Background technique [0002] The valve hall of the converter station of the UHV DC transmission system is a closed space, in which there are converter valves, transformer bushings, wall bushings and other equipment. Different equipment needs to be connected by pipe bus to form a transmission circuit. For the conversion of AC and DC, since the influence of earthquake, thermal expansion and contraction of materials, electromotive force, corona, etc. working conditions. [0003] In the installation of the suspension insulator fittings, it is necessary to connect the suspension insulator with the shielding ball fittings to suspend and fix the shielding ball fittings. The Chinese invention patent application with the application publication number CN103296623A discloses a kind of pipe bus suspension fittings for the valve hall of the converter station, such as figure 1 As shown, it includes the...
