Bus bridge structure and bus bridge system

Abstract

The invention provides a bus bridge structure and a bus bridge system. The bus bridge structure comprises a vertical bridge body and a horizontal bridge body, wherein the horizontal bridge body comprises an A-phase adapter bar and a C-phase adapter bar. According to the bus bridge structure, the adapter bars used for commutation are arranged on the horizontal bridge body, in order to ensure a safe distance, the A-phase adapter bars and the C-phase adapter bars are arranged in the horizontal bridge body up and down at intervals, the upper space and the lower space of the horizontal bridge body are occupied during commutation, the horizontal bridge body is located above the vertical bridge body, the bus bars of each phase of the vertical bridge body part vertically extend upwards, and the depth of the vertical bridge body in the front-back direction is small. When the box body surrounds the vertical bridge body, the vertical bridge body is installed above the switch cabinet, the depth of the vertical bridge body is small, the box body base can be completely borne on the top face of the switch cabinet below, the situation that the box body base extends out of the switch cabinet and influences normal opening of other top pressure relief plates of the switch cabinet is avoided, and normal pressure relief of adjacent switch cabinet compartments is guaranteed.

Description

technical field [0001] The invention relates to the technical field of high-voltage switch cabinets, in particular to a bus bridge structure and a bus bridge system. Background technique [0002] The switchgear is limited by the space of the on-site power distribution room, and often needs to be arranged in two or more rows. At this time, if it is necessary to connect the busbars of two or more rows of switch cabinets, it is often necessary to use busbar bridges, power cables or pipe-type Busbar and other schemes for connection. Among them, the connection method of the busbar bridge is the most economical and safe. The phase sequence of the switchgear is based on the requirements of regional or technical agreements. Facing the switchgear, A, B, and C are arranged in order from left to right. When two switchgears are arranged facing each other, if the busbar bridge is directly connected to the two face-to-face switchgears without commutation, the phase sequence of the busba...

AI Technical Summary

Problems solved by technology

The busbar bridge includes a vertical bridge body located in the lower casing of the commutation phase. In the vertical bridge body, the commutation is realized by connecting the same-phase busbars on both sides through the commutation copper bar. In order to ensure a sufficient safety distance in the vertical bridge body, the commutation The phase copper bar needs to be extended for a certain distance away from one side of the bus bar, and then bent towards the same phase bus bar on the other side. The depth of the vertical bridge body is deeper than that before the commutation, and the excess part of the vertical bridge body is in contact with the pressure relief plate on the top of other compartments of the switchgear, which will affect the normal opening of the pressure relief plate in this compartment
