Abstract

The invention discloses a heat dissipation control method, device and system for an electrical cabinet. Among them, the method includes: predicting the amount of heat generated in the electrical cabinet; determining the corresponding amount of heat dissipation based on the predicted amount of heat generation; and controlling the speed of the cooling fan so that the difference between the amount of heat generated and the amount of heat dissipated is within a predetermined range. The invention solves the technical problem that the existing heat dissipation control method of the electrical cabinet controls the rotation speed of the cooling fan by detecting the ambient temperature in the electrical cabinet, but the control is lagging behind and the temperature is prone to fluctuations.

Description

technical field [0001] The present invention relates to the field of electrical cabinets, in particular to a heat dissipation control method, device and system for an electrical cabinet. Background technique [0002] As clean energy, electric energy plays a very important role in industrial production and people's daily life. Various electrical cabinets play an irreplaceable role as terminal equipment for controlling the use of electric energy. However, these electrical cabinets face Among them, the heat generation and heat dissipation of the conductive parts in the electrical cabinet is a typical problem, especially for high-power electrical cabinets. When the high-power electrical cabinet is running, the current is large, and the heat generated is also relatively large, which puts forward higher requirements for the heat dissipation of the electrical cabinet. [0003] The heat dissipation control method widely used at present is generally to detect the ambient temperature...
