Abstract

The invention discloses a regulation control method for a cooling fan of a switch cabinet, and the regulation control method is applied to a cooling fan system. The cooling fan system comprises a temperature probe, a first set of fans and a second set of fans, and the temperature probe, the first set of fans and the second set of fans are installed at the same area. According to the method, after the current of the switch cabinet and ambient temperature are monitored, graded regulation control over the first set of fans and the second set of fans is achieved, and the refrigerating capacity of the fans is regulated; repeated start and stop of the fans are avoided, and the situation that the fans continuously run at high load even when the fans are not needed is avoided; therefore, the service life of the fans is prolonged; furthermore, by setting the first preset time before the first group of fans are stopped and the second preset time before the second group of fans are stopped, delayed shutdown of the fans is realized; and the possibility of damage due to frequent start and stop of the fans is further reduced.

Description

technical field [0001] The present application relates to the technical field of fan regulation, in particular to a method for regulating and controlling a cooling fan of a switchgear. Background technique [0002] Existing air-cooling control systems for switchgear in substations are generally cooled by a single fan with constant power. In this way, when the critical value of fan start and stop fluctuates, the fan may start and stop frequently and be easily damaged. Contents of the invention [0003] In view of this, the purpose of this application is to provide a control method for adjusting and controlling the cooling fan of the switchgear, which is used to optimize the start-stop control mode of the fan and reduce the possibility of fan damage. [0004] In order to achieve the above technical purpose, this application provides a method for adjusting and controlling the cooling fan of the switchgear, which is applied to the cooling fan system. The cooling fan system inc...
