Abstract

The invention discloses a large electromechanical equipment heat dissipation control method and device, and the method comprises the steps: synchronously starting a heat dissipation motor to operate at low frequency according to a starting command of the large electromechanical equipment; calculating the equivalent heating value of the large electromechanical equipment in an adjusting period based on the three-phase current amplitude; and calculating the given frequency of the heat dissipation motor through the equivalent heating value, wherein the heat dissipation motor adjusts the operation rotating speed according to the given frequency. The heat dissipation loss is calculated according to the operation information of the large electromechanical equipment, the operation frequency of the heat dissipation motor is adjusted through the heat dissipation loss, and the purpose of efficient heat dissipation control is achieved.

Description

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