Support fitting of double tubular bus bars

Abstract

The present invention discloses a support fitting of double tubular bus bars, and relates to the convertor station direct current field fitting technology field. The objective of the invention is to solve the problems that the connection between the tubular bus bar on a direct current transformer station and a tubular bus bar on a capacitor tower is complex in operation and the connection structure is unstable so that the accidents easily happen. The support fitting comprises a support frame a first tubular bus bar hoop and a second tubular bus bar hoop, the central axis of the first tubular bus bar hoop is horizontally arranged, the first tubular bus bar hoop is slidingly connected with the support frame along the extension direction of the central axis itself, the central axis of the second tubular bus bar hoop is vertically arranged, and the second tubular bus bar hoop is hinged on the support frame through a hinging structure. The support fitting of double tubular bus bars is configured for the converter station direct current field.

Description

technical field [0001] The invention relates to the technical field of a direct current field fitting of a converter station, in particular to a double-pipe female supporting fitting. Background technique [0002] At present, my country has become a major DC power transmission country with the most DC projects in operation and under construction, the largest capacity and the longest lines in the world. The converter station is an important part of the DC transmission project. The DC field in the converter station uses a large number of connection methods between the tube bus and the tube bus, especially the connection between the tube bus on the DC substation and the tube bus on the capacitor tower. connection between. [0003] At present, the connection method between the pipe busbar on the DC substation and the pipe busbar on the capacitor tower is as follows: one pipe mother support fitting is used to support the pipe busbar on the DC substation, and another pipe mother ...

AI Technical Summary

Problems solved by technology

[0004] However, the operation process of connecting two pipe busbars through fittings, soft wires and fittings is cumbersome, time-consuming and laborious, and because the two fittings are connected by soft wires, the length of the soft wires is not easy to determine, and the soft wires are easy to swing under the action of wind swing Deformation, the charging distance from the capacitor tower is difficult to guarantee, so there are potential safety hazards
