Low-voltage distribution box

Abstract

The invention provides a low-voltage distribution box which comprises a box body, circuit breakers arranged inside the box body and a transparent box door connected to the box body through hinges. The box door is provided with an automatic door handle; the cross section of the door frame edge of the box body is a V-shaped groove, wherein the opening of the V-shaped groove faces to the outer side of the box body; the door edge of the box door is a slope edge; and the box door fully covers the door frame edge, the cross section of which is the V-shaped groove, of which the opening faces to the outer side, of the box body. The beneficial effects are that with the above technical scheme, work personnel can observe the states of the circuit breakers inside the box body visually and conveniently, so that various power distribution loops are effectively controlled, and safety is better; since the door frame edge of the distribution box body and the slope edge of the box door form multiple waterproof barriers, ventilation and heat dissipation functions are achieved, and the service life of the distribution box is prolonged; and the low-voltage distribution box has the advantages of being simple and reasonable in structure, convenient and practical, safe and reliable, good in ventilation and convenient to dissipate heat and reduce the temperature and the like.

Description

technical field [0001] The invention belongs to the technical field of power distribution equipment, in particular to a low-voltage power distribution box. Background technique [0002] Low-voltage distribution boxes are suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries, as power transmission, power distribution and power conversion. In the existing technology, the box body of the distribution box is mostly made of opaque materials. When in use, the staff cannot easily see the opening and closing status of the internal miniature circuit breaker. They need to open the box door to see it. It is not convenient for the staff to intuitively check the state of the miniature circuit breaker in the distribution box and effectively grasp each power distribution circuit. Moreover, the rainproof performance of the distribution box is poor, and rainwater can easily flow into the distribution box. In the light case, t...

Problems solved by technology

In the existing technology, the box body of the distribution box is mostly made of opaque materials. When in use, the staff cannot easily see the opening and closing status of the internal miniature circuit breaker. They need to open the box door to see it. It is not convenient for the staff to intuitively check the status of the miniature circuit breaker in the distribution box and effectively grasp each distribution circuit

Moreover, the rainproof performance of the distribution box is poor, and rainwater can easily flow into the distribution box. In the light case, the insulation strength inside the distribution box will be reduced, leaving a safety hazard. In severe cases, the circuit in the distribution box may be short-circuited, resulting in a power failure , affecting the normal work and life of users

There are technical problems such as complex structure, time-consuming and labor-intensive adjustment, low work efficiency, poor safety performance, etc.
