Problems solved by technology

This heat dissipation device cannot be adjusted in real time according to the specific conditions of the heat generated inside the power distribution cabinet, and the heat dissipation effect is not good
If the traditional automatic control heat dissipation system is used, high-speed computing devices and complex air circulation control mechanisms are required, and the cost is too high

Abstract

The invention discloses a cooling system of a power distribution cabinet and a control method thereof. There are several second temperature sensors, the ratio of the maximum value to the minimum value of the distance between any two second temperature sensors is not greater than 3:1, a controller is arranged in the cabinet, and the input terminal of the controller is connected to the first temperature sensor and the second temperature sensor. The temperature sensor is connected in communication, and the output terminal of the controller is connected in communication with the control terminal of the reversing fan. The invention can improve the deficiencies of the prior art, realize precise control of the heat dissipation of the power distribution cabinet while effectively controlling the cost.

Description

technical field [0001] The invention relates to an electrical device, in particular to a heat dissipation system of a power distribution cabinet and a control method thereof. Background technique [0002] Power distribution cabinet is a kind of electrical equipment widely used in production sites under various working conditions. The power distribution cabinet will generate a lot of heat when it is working. In order to ensure the normal operation of the power distribution cabinet, it needs to be effectively dissipated. The existing heat dissipation system of the power distribution cabinet is generally only one or more exhaust fans to realize the air flow inside and outside the power distribution cabinet, thereby realizing heat dissipation. This heat dissipation device cannot be adjusted in real time according to the specific conditions of the heat generated inside the power distribution cabinet, and the heat dissipation effect is not good. If the traditional automatic cont...
