Abstract

The invention discloses a power distribution box, which comprises a box body. The front end of the box body is provided with a first opening, the upper and lower ends of the box body are provided with first ventilation holes penetrating through the outer wall of the box body, and the upper and lower ends of the inner wall of the box body are both slidable. An isolation plate is installed, and second ventilation holes are arranged on the isolation plate, and the first spring is fixed on the left end of the isolation plate, and an isolation tank is installed in the box, and the end of the isolation tank is provided with a second opening, and the second opening An end cover is plugged on the top, and a heat-sensitive support is touched on the end cover. The end of the heat-sensitive support touches the guide rod on one side of the drive rod, and the first air hole communicates with the second air hole. The present invention can increase the circulation of the air in the box by setting the normally open first air hole and the second air hole, effectively reducing the working temperature of the components in the box, and when the temperature in the box reaches a certain value, the second air hole It is staggered with the first ventilation hole to isolate the air circulation in the box and assist in fire extinguishing.

Description

technical field [0001] The invention relates to the field of distribution boxes, in particular to a distribution box. Background technique [0002] A distribution box is a commonly used electrical infrastructure. When the electronic components inside the distribution box work, a lot of heat will be generated, and the ordinary distribution box only dissipates heat through the opening of cooling holes. The applicant found the following problems in the use of the distribution box: the huge heat generated by the box in a short time is easy to cause a fire, and because the cooling holes of the box cannot be closed, the fire in the box cannot be controlled. It is easy to spread. Contents of the invention [0003] In view of this, the purpose of the present invention is to propose a distribution box to solve all or one of the problems in the background technology. [0004] Based on the above purpose, the present invention provides a distribution box, comprising a box body, the...
