Title: ELECTRICAL CABINET HEAT DISSIPATION CONTROL METHOD, APPARATUS AND SYSTEM
Abstract:
Disclosed in the present invention are an electrical cabinet heat dissipation control method, an apparatus and a system. Wherein the method comprises: predicting the calorific value in the electrical cabinet; determining a corresponding heat dissipation value according to the predicted calorific value; and controlling a difference between the calorific value and the heat dissipation value within a predetermined range by controlling rotation speed of a radiating fan. The invention solves a technical problem of lagging control and fluctuation of temperatures caused by the existing heat dissipation control method of the electrical cabinet in which the rotation speed of the radiating fan is controlled upon detection of ambient temperatures in the electrical cabinet.
