Low-voltage power distribution structure cabinet

Abstract

The invention relates to a low-voltage power distribution structure cabinet. The low-voltage power distribution structure cabinet comprises a bottom structure and a top structure, wherein the top structure and the bottom structure are fixedly connected through four stand columns, the top structure comprises an outgoing wire chamber and a main busbar chamber which are horizontally arranged, transverse beams are arranged around the bottoms of the outgoing wire chamber and the main busbar chamber, the transverse beams are perpendicularly fixed between adjacent stand columns, a cabinet center beam and two longitudinal beams are arranged in the middle of the outgoing wire chamber and the main busbar chamber, the bottom ends of the two longitudinal beams are perpendicularly fixed with the transverse beams, the two ends of the cabinet center beam are respectively and fixedly connected with the tops of the two longitudinal beams, top beams are respectively arranged between the tops of the stand columns of the outgoing wire chamber and the main busbar chamber, and the top beams of the outgoing wire chamber are connected with the cabinet center beam through connecting beams. The low-voltage power distribution structure cabinet has the advantages that the structure is stable and compact, the strength is high, the size is small, the demands of site installation and hoisting can be met, and the problem that a hole needs to be excavated due to a small installation space is overcome.

Description

technical field [0001] The invention relates to a low-voltage power distribution structure cabinet, which belongs to the field of machinery. Background technique [0002] The top structure of the bus bar on the top of the conventional power distribution cabinet is a square hole structure, and the bus bar runs through the top of each power distribution cabinet. The type of busbar has a single type, that is, each power distribution cabinet is equipped with a busbar, and the busbar between the power distribution cabinet and the power distribution cabinet is connected by connecting the busbar connection block. Due to the increase of the copper busbar connection block, the price of the copper busbar is high, and the power distribution cabinet The cost will increase a lot, which is uneconomical and energy-saving. Now, in order to reduce the cost, each manufacturer makes the whole group of distribution cabinet busbars into 5~6 power distribution cabinets sharing a set of top mai...

AI Technical Summary

Problems solved by technology

Now, in order to reduce the cost, each manufacturer makes the whole group of distribution cabinet busbars into 5~6 power distribution cabinets sharing a set of top main busbars that can pass through the length. During on-site installation, the busbars need to be passed through the side of the whole group of power distribution cabinets. Into the square hole on the top of the busbar room, so that the site needs a lot of space

However, when the space in the power distribution room is limited and there is no distance between the two ends of the switchgear arrangement, it is necessary to dig holes in the wall to ensure the penetration of the entire main busbar. This method is time-consuming and laborious.
