Embodiment Construction

[0019] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0020] Such as Figure 1-3 As shown, a DC power supply box includes a box body and a box door. In this embodiment, the box body is a cube, and the box door is hinged on the front side wall of the box body. The box eaves 11, that is, the outer ring of the box eaves 11 is larger than the main part of the box body, and the edges of the box eaves 11 are chamfered. When it rains, the box eaves 11 can well protect the main body of the box body. There is a control circuit and a battery in the box, and the control circuit is connected with a low-voltage protection relay and a lightning protector. The low-voltage protection relay can effectively avoid secondary distribution under low-voltage conditions, reduce the failure rate of equipment, and the lightning protector plays a role For overpressure protection, there is a drainage channel 101 connected betw...

Abstract

The invention discloses a DC power box, comprising a box body and a box door, wherein the box body is internally provided with a control circuit and a battery; the control circuit is connected with a low-voltage protection relay and a lightning arrester, a drainage passage is connected between the top and the bottom of the box body and is arranged in the side wall of the box body. With adoption of the DC power box, such problems of the existing DC power box, such as absence of low-voltage protection and poor heat dissipating effect, can be solved.

Description

technical field [0001] The invention relates to a DC power supply box, which belongs to the field of electric equipment. Background technique [0002] DC power supply box, also called DC distribution box, is a kind of power equipment commonly used in power system. It is equipped with control circuit inside to realize power distribution and switch closing, and many DC power supply boxes are placed in the open air. In order to ensure its The internal control circuit is not affected by the outside world. The DC power box must have good waterproof, lightning protection, and heat dissipation effects. However, the existing DC power boxes are not very good in these aspects, especially the heat dissipation effect. Direct ventilation is used to achieve simple heat dissipation, and the existing DC power box does not have enough protection measures for low voltage. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a DC power...
