Problems solved by technology
The power distribution cabinet is often unavoidably attacked by water. If water drips vertically or obliquely into the interior of the power distribution cabinet from the top of the power distribution cabinet, the components of the power distribution cabinet will be soaked in water, resulting in short circuit of electrical equipment and failure to operate normally.
In order to solve the problem of rainwater dripping vertically or obliquely from the top of the power distribution cabinet, the whole body of the power distribution cabinet is designed as a sealed structure in the prior art. Although the waterproof problem of the power distribution cabinet is solved to a certain extent, it is ignored. Heat dissipation problem of power distribution cabinet
There is also a very difficult problem to solve: when there is heavy rain and a lot of water on the ground, it is easy to enter the interior of the power distribution cabinet through the ventilation and heat dissipation holes of the power distribution cabinet or the gap between the cabinet doors, resulting in short circuit of the circuit inside the power distribution cabinet
Therefore, the power distribution cabinet for high-voltage power distribution system seems to be contradictory to the two problems of heat dissipation and waterproof. It is difficult to achieve good waterproof if the heat dissipation is solved, and it seems difficult to solve the heat dissipation problem if the waterproof problem is solved.

The invention discloses a high voltage distribution system power distribution cabinet. The power distribution cabinet comprises a cabinet body. A cabinet body front portion is provided with a cabinet door. A plurality of transverse separation plates which are parallel to a cabinet body bottom surface is arranged in the cabinet body. A cavity is formed between the transverse separation plates. Each transverse separation plate is a hollow cuboid structure. Upper and lower surfaces of each transverse separation plate are provided with a plurality of air outlets. A side surface of each transverse separation plate is provided with one air inlet. A temperature sensor, a controller, a draught fan and a flexible blast pipe are included. The temperature sensor is arranged in the cabinet body. A temperature signal collected by the temperature sensor is input into the controller and the controller controls starting and stopping of the draught fan. The flexible blast pipe contains one input port and two output ports, an air outlet of the draught fan is connected to the input port of the flexible blast pipe and the output ports of the flexible blast pipe are connected to air inlets of the plurality of the transverse separation plates respectively. A circular rain ceiling and a round-barrel-shape waterproof apparatus are included. By using the power distribution cabinet, an internal heat dissipation problem of the power distribution cabinet is effectively solved and a waterproof effect is good.
Description
[0001] This application is a divisional application of a patent application with an application date of 2015-02-05, an application number of 201510061964.1, and an invention name of a high-voltage power distribution system power distribution cabinet. technical field [0002] The invention relates to a power distribution cabinet, in particular to a power distribution cabinet with good waterproof performance, and belongs to the technical field of electric equipment. Background technique [0003] The power distribution cabinet is divided into the power distribution cabinet and the lighting distribution cabinet, and is the final equipment of the power distribution system. The power distribution cabinet is often unavoidably attacked by water. If water drips vertically or obliquely into the interior of the power distribution cabinet from the top of the power distribution cabinet, the components of the power distribution cabinet will be soaked in water, resulting in short circuit of...
