Cabinet body of low-voltage power distribution cabinet for boats

Abstract

The invention provides a cabinet body of a low-voltage power distribution cabinet for boats and belongs to the field of cabinet bodies of electrical equipment. The cabinet body comprises a cabinet body frame, a front door plate, a rear seal plate, a top seal plate, a bottom seal plate and a side seal plate and is characterized in that: the cabinet body frame comprises a pair of frames and four longitudinal beams; the pair of frames are arranged opposite to each other and in parallel and are connected through the longitudinal beams; each frame comprises two transverse beams and two vertical columns; the transverse beams and the vertical columns adopt sectional materials with the same structure and are assembled into a rectangular frame; a waterproof folding edge is formed on the inner frame of the frame; a first U-shaped groove is formed on the outer frame of the frame; each longitudinal beam comprises a first folding edge; a second folding edge is formed on one side of the first folding edge; a third folding edge is formed on the other side of the first folding edge; a second U-shaped groove is formed on the other side of the second folding edge; a third U-shaped groove is formed on the other side of the third folding edge; and angle seam sealing pieces are arranged four corners, connected with the longitudinal beams, of the frames. The cabinet body has the advantages of high integrated strength, high weather resistance, high protection grade, high generality and convenience for assembling and disassembling.

Description

technical field [0001] The invention belongs to the technical field of cabinet structure of electrical equipment, and in particular relates to a marine low-voltage power distribution cabinet cabinet . Background technique [0002] The power distribution cabinet is used in the occasions where the load is relatively dispersed and the circuit is small. The ship power distribution device is one of the important components of the ship power system. Equipment for load distribution, protection, measurement and adjustment of generators and grids. Since the ship is an isolated independent body that moves on the ocean, the ship power system is very different from the land power system, mainly as follows: the capacity of the ship power station is small, the transmission line of the power grid is short, so that the voltage level is small, It is simpler than the land system; the working environment of the ship's electrical equipment is harsh, and the environmental conditions have a s...

AI Technical Summary

Problems solved by technology

[0003] However, most of the existing marine low-voltage power distribution cabinet cabinet frames are directly obtained by borrowing the land cabinet frame (or its modification), and are not obtained from Fundamentally solve the problem of strength and protection level at the same time

For example, the "a kind of ship power distribution cabinet" disclosed by the Chinese utility model patent authorization announcement number CN202183563U has the advantages of convenient assembly and simple structure, but it has not been compared with "ship conditions" in terms of strength and protection level. improvement of
