Abstract

The invention relates to the technical field of electrical fittings, in particular to a distribution box heat dissipation system. A heat dissipation hole is formed in a box body, a plurality of partition pieces are arranged in the heat dissipation hole, the partition pieces all incline downwards and face the interior of the box body from the exterior of the box body, a baffle piece capable automatically restoring is hinged to the top of the heat dissipation hole, the gradient of the baffle piece is equal to those of the partition pieces, the width of the baffle piece is greater than those of the partition pieces, a water bag for collecting rainwater is arranged between the baffle piece and the box body, and the end of the partition piece adjacent to the baffle piece is provided with a photo-resistor which is arranged at the outer side of the box body; the distribution box heat dissipation system further includes a controller for receiving the resistance value of the photo-resistor, a plurality of ventilation holes are formed in a bottom plate of the box body, and seal pieces capable of being opened are arranged in the ventilation holes and are controlled by the controller to be opened according to the resistance value. According to the distribution box heat dissipation system, when it rains, the baffle piece shades the partition pieces below the baffle piece and shades the heatdissipation hole under the baffle piece from rain, the situation is avoided that rainwater enters the interior of the box body through the heat dissipation hole, and it is ensured that electrical elements in the box body run normally.

Description

technical field [0001] The invention relates to the technical field of electrical accessories, in particular to a cooling system for a distribution box. Background technique [0002] The distribution box has a wide range of applications, involving various aspects such as industry, agriculture, transportation and people's life. The distribution box is to assemble switchgear, measuring instruments, protective appliances and auxiliary equipment on metal cabinets or screens according to electrical wiring requirements. In order to distribute the electric energy reasonably, it is convenient to open and close the circuit. [0003] When the existing distribution box is working, the internal electrical components will emit heat, which will increase the temperature in the distribution box and affect the operation of the electrical components. Generally, the fan is used to fan the heat, and the fan will transfer the heat from the distribution box. The heat dissipation holes are conduc...
