XL power distribution box with good protection performance

Abstract

The invention discloses an XL power distribution box with good protection performance, and the box comprises a box body and a buffer protection device; the outer wall of the top of the box body is fixedly connected with the buffer protection device, the top of the buffer protection device is fixedly connected with a protective shed, and the outer wall of the bottom of the box body is fixedly connected with two base tables. Through the arrangement of a buffer protection device, the top of the distribution box is conveniently buffered and protected, the protective shed can effectively block objects falling from high altitude, when the protective shed is impacted, a supporting rod moves downwards and drives an H-shaped column to move, the H-shaped column slides on the inner wall of an arc-shaped groove, and a connecting frame moves downwards to extrude a buffer spring; the connecting frame moves towards the side away from the box body at the same time, the moving block slides on the innerwall of the moving groove, the moving rod moves along with movement of the connecting frame, the buffer rod moves at the same time and drives the reset spring to stretch, the impact force generated when the protective shed is impacted by heavy objects can be effectively buffered, damage to the top of the distribution box is avoided, and the buffer and protection effects are better.

Description

technical field [0001] The invention belongs to the technical field of distribution boxes, and in particular relates to an XL power distribution box with good protection. Background technique [0002] The power distribution box is divided into the power distribution box and the lighting distribution box, which is the final equipment of the power distribution system. Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to p...

Problems solved by technology

[0004] The purpose of the present invention is to provide a XL power distribution box with good protection, so as to solve the problem that during the use of the existing power distribution box proposed in the above-mentioned background technology, since the top of the distribution box is fixed, there is no Set the buffer device, when falling objects from high altitude, it is easy to hit the top of the distribution box, and the inside of the distribution box is equipped with a motor to drive the cooling fan to dissipate heat. The motor will also generate heat when it works for a long time, and the outdoor distribution box The bottom of the distribution box is easy to get wet, which will lead to damage to the distribution box, the protection effect is poor, the damage will affect the heat dissipation, and the use effect is poor, which will affect the use of the internal components of the distribution box.
