Armored movable alternating-current metal-enclosed switchgear

Abstract

The invention discloses an armored movable alternating current metal-enclosed switchgear. The switchgear comprises a switch cabinet body and a bottom box, a vertical pipe is fixedly connected to the bottom of an inner cavity of the switch cabinet body, and a ventilator is fixedly connected to the bottom of the inner cavity of the switch cabinet body and located in the inner cavity of the verticalpipe. Air inlet pipes are communicated with the two sides of the vertical pipe, and one end of each air inlet pipe extends out of the switch cabinet body. According to the present invention, the fan blades are driven to rotate through the output shaft of the ventilating fan, therefore, airflow is generated and is blown upwards through an air nozzle, and the electric appliance elements in the innercavity of the switch cabinet body are cooled, wherein air enters from the air inlet pipes and are out from an air outlet hole; the problems that the temperature of the inner cavity of the switch cabinet body is too high to cause element damage; the existing armored movable alternating-current metal-enclosed switchgear is worse in heat dissipation performance, and the short circuit or component burnout occurs due to the fact that the temperature in the box is too high in the using process, so that the service life of the switchgear is shortened, are solved.

Description

technical field [0001] The invention relates to the technical field of power distribution equipment, in particular to an armored removable AC metal-enclosed switchgear. Background technique [0002] Among the power distribution equipment, the armored removable AC metal-enclosed switchgear is an important part, which plays the role of opening and closing, control and protection in the process of power generation, transmission, distribution and power conversion in the power system, so It has been widely used in the distribution network. The existing armored removable AC metal-enclosed switchgear has relatively poor heat dissipation performance. During use, due to overheating in the box, short circuits may occur or components will be burned. phenomenon, reducing the service life of the switchgear. Contents of the invention [0003] The purpose of the present invention is to provide an armored removable AC metal-enclosed switchgear, which has the advantages of high-efficiency...
