Three-phase conductor conversion joint

Abstract

The invention relates to a three-phase conductor conversion joint. The joint comprises a sealing barrel and sealing flanges mounted at two ends of the sealing barrel. The two sealing flanges are respectively and horizontally provided with three adapter inserts and vertically provided with three adapter inserts; a three-phase conductor is arranged in the sealing cylinder, conductors on two sides comprise bent sections, the bent sections of the conductors on the two sides are symmetrical about the center of a middle conductor, and ends of the two sides of the three-phase conductor are in a horizontal line shape and a vertical line shape respectively due to the bent sections and used for being connected with corresponding switching inserts on the two sealing flanges. During use, the three-phase conductor conversion joint can convert the linear arrangement mode of the three-phase conductor of a gas insulated metal-enclosed switchgear, and when reversing wiring in the linear extension direction is needed, the linear arrangement mode can be changed firstly, and the wiring is changed into reversing wiring in the direction perpendicular to the linear direction, so that interference among the conductors is avoided; after the two groups of three-phase conductor conversion joints are butted together, the phase sequence exchange can be realized on the basis of not changing the linear arrangement mode.

Description

technical field [0001] The invention relates to a three-phase conductor conversion joint. Background technique [0002] At present, most of the gas-insulated metal-enclosed switchgears on the market today are designed in a three-phase common box. The advantages of simple structure and high common rate of three-phase parts are gradually accepted by the market. However, in the structure where the three phases are arranged in a zigzag, under special working conditions, the three-phase conductors need to be switched back and forth between the vertical zigzag and horizontal zigzag arrangements, or the phase sequence exchange between phase A and phase C is required , but currently there is no good way to realize the transformation of the layout and the exchange of phase sequence. Contents of the invention [0003] The purpose of the present invention is to provide a three-phase conductor conversion joint to solve the problem that the gas-insulated metal-enclosed switchgear wit...
