Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinet characteristic detection devices, and particularly relates to a switch cabinet characteristic detection device. Background Art

[0002] The switch cabinet is an important component in the power system, which has the functions of isolating, protecting, and controlling electric energy. To ensure its normal operation and safe use, it is necessary to seal it to prevent external substances such as dust and moisture from entering the interior and affecting the normal operation. The sealing problem at the opening also needs to be considered. Sealing strips are installed in areas such as terminal blocks and electrical components to avoid water and dust ingress, achieving excellent waterproof and dustproof effects.

[0003] In the prior art, a sealed switch cabinet with the publication number of CN103346487A includes a front sealing plate, side sealing plates, and a rear sealing plate that are spliced together. The seams between the sealing plates are filled with sealing rubber strips. The height of the sealing rubber strips filled around the front sealing plate is greater than that of the sealing rubber strips filled in other parts. A pressure sensor is arranged inside the switch cabinet, and a silica gel surface coating is applied to the surface of the sealing rubber strips filled around the front sealing plate. After adopting the above structure, due to the characteristics of the sealing rubber strips themselves, the sealing between the seams will be more uniform and easy to seal, and it is also easy to replace after sealing. Because the height of the sealing rubber strips filled around the front sealing plate is greater than that of other parts, and there is a silica gel surface layer on the surface of the sealing rubber strips at this place, it is more wear-resistant and will not reduce the sealing performance of the switch cabinet due to the frequent opening and closing actions of the front sealing plate, thus prolonging the service life of the sealing rubber strips. In addition, the use of the pressure sensor can monitor the sealing performance of the switch cabinet and give an early warning by detecting the change of pressure inside the switch cabinet. However, the detection of the sealing characteristics is not accurate enough, and it cannot detect each opening edge one by one, resulting in poor detection effects.

[0004] Therefore, the utility model proposes a switch cabinet characteristic detection device with high accuracy in detecting sealing characteristics and capable of detecting section by section to solve such problems. Content of the Utility Model
