A multi-functional low-voltage withdrawable switchgear

Abstract

The invention discloses a multifunctional low-voltage withdrawable switchgear, which belongs to the technical field of electric power equipment, and includes a switchgear basic device, a hydraulic shockproof device, a main flow cooling device, and an auxiliary flow cooling device. The periphery of the switch cabinet base device is provided with a hydraulic shockproof device, the switch cabinet base device is provided with a main flow cooling device inside, and the main flow cooling device is provided with a secondary flow cooling device. The present invention is scientific and reasonable. It is safe and convenient to use. On the basis of the existing low-voltage switchgear, the cooling and shockproof treatment of the extraction cabinet area is optimized, and the cold air in the low-altitude place in the environment where the switchgear is located is drawn into the interior for circulating cooling, which is low in cost and Pulling out any drawer alone will not affect the circulation cooling effect. The anti-shock design of this device will not cause the drawer to vibrate back and forth due to the elastic effect of the spring.

[0002] Low-voltage switchgear is a product listed in the "Catalogue" of 3C certification compulsory certification products. It is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries. It is used for power transmission, distribution and power conversion. Low-voltage switchgear It can be divided into GCS low-voltage switchgear, GCK withdrawable switchgear, GGD low-voltage fixed switchgear, assembled low-voltage switchgear, etc. The low-voltage switchgear is designed in units according to the characteristics of various switch electrical appliances such as escape ports and drawings. Combined into functional units, the design is reasonable, and has the characteristics of flexible assembly. The isolation between areas and the mutual isolation between the incoming and outgoing lines of the functional units are adopted, and the protection performance is excellent. However, the extraction in the low-voltage switchgear in the prior art The cabinet is easy to cause impact during use, causing damage to the electrical components or lines in the low-voltage extraction cabinet, and in the state of long-term operation of the electrical components in the extraction cabinet, it is easy to cause the temperature in the cabinet to rise, affecting the power and service life of internal components. , so people need a multifunctional low-voltage withdrawable switchgear to solve the above problems
