Problems solved by technology

[0004] At this time, increasing the ampacity only by enlarging the outer diameter of the pipe busbar and increasing the cross-sectional area of ​​the pipe busbar will bring many problems: 1. It is difficult or even impossible to choose suitable supporting installation materials, such as fixing fittings, connecting fittings, post insulators Wait
2. The increase in weight per unit length causes difficulties in manufacturing and installation

Abstract

The invention discloses an extra-large current tubular bus bar, which is characterized in that each phase of three-phase alternating current is transmitted through a plurality of tubular bus bars arranged in parallel, and a plurality of spacing fittings are arranged among the plurality of tubular bus bars arranged in parallel. The method has the advantages that the bus design of the extra-large current is realized by adopting the tubular bus with the conventional size, the selection of matched mounting materials of the bus is facilitated, and the difficulty in actual manufacturing and mounting is avoided.

Description

technical field [0001] The invention relates to a super-large current tube busbar, which belongs to the technical field of power electronics. Background technique [0002] Static var compensator is a fast, smooth and controllable dynamic reactive power compensation device without rotating parts. In the power system, the static var compensator is often used to realize voltage regulation, provide reactive power support, reduce temporary overvoltage, etc., and improve the overall power quality of the power system. [0003] Considering the overall economy, each reactive power compensation branch of the static var compensator usually works at a medium voltage level; and a medium-voltage busbar is set up to connect each branch, and after converging, it is connected to the high-voltage system through a transformer step-up. In general, the current of the medium-voltage busbar is several thousand amperes, and a single tubular busbar is used. However, the capacity of individual stat...
