Abstract

The invention discloses a heat dissipation control method and device for large electromechanical equipment. The method includes: synchronously starting a heat dissipation motor to run at a low frequency according to a start command of the large electromechanical equipment; Equivalent calorific value in the cycle; through the equivalent calorific value, the frequency reference of the cooling motor is calculated; the cooling motor adjusts the running speed according to the frequency reference. The invention calculates the heat dissipation loss according to the operation information of the large electromechanical equipment, adjusts the operation frequency of the heat dissipation motor through the heat dissipation loss, and realizes the purpose of efficient heat dissipation control.

Description

technical field [0001] The present invention relates to the technical field of heat dissipation, and in particular, to a heat dissipation control method and device for large electromechanical equipment. Background technique [0002] Large electromechanical machines are widely used in various industrial fields, such as steel mills, coal mines, ports and other occasions. They generate a lot of heat during operation and require good heat dissipation methods and heat dissipation methods. If the heat dissipation effect is poor, it will not only lead to insulation damage of large electromechanical equipment due to overheating, but also lead to short circuit failure of the motor due to insulation damage, resulting in major economic losses; on the other hand, the high temperature of large electromechanical equipment will affect the equipment. life, resulting in reduced equipment reliability. [0003] In the prior art, the heat dissipation of the electromechanical equipment is contr...
