Abstract

The invention discloses a large current drawout switch cabinet comprising a universal cabinet, a horizontal bus frame arranged in the upper space inside the universal cabinet, a bus frame arranged below the horizontal bus frame, main buses arranged on the horizontal bus frame and the bus frame, and a supporting piece arranged in the middle space inside the universal cabinet to support the main buses. The supporting piece is provided with an insulator. According to the large current drawout switch cabinet provided by the invention, a series of problems of the large current drawout switch cabinet is well solved, and the problems of overhigh temperature of the cabinet, overloud system noise, large loss and the like caused by vortex are solved.

Description

technical field [0001] The invention relates to a large current withdrawable switchgear. Background technique [0002] The 0.4kV high-current withdrawable switchgear is widely used in some factories and real estates with relatively large power consumption. The existing standard 0.4kV withdrawable switchgear structure is used in high-current systems, and the problem of eddy current generation has not been solved. Good solution. Since the current goes to the 4000A ~ 6000A system, the eddy current problem will have a particularly obvious impact on the system, causing a series of problems such as high cabinet temperature, high noise, and large loss. Contents of the invention [0003] The main purpose of the present invention is to provide a large current withdrawable switchgear that effectively suppresses temperature rise, noise and loss. [0004] In order to solve the above problems, the present invention adopts the following technical solutions: a large current draw-out sw...
