Description

Technical Field

[0001] The utility model belongs to the technical field of switch cabinets, and particularly relates to a cabinet door sealing structure for a switch cabinet. Background Art

[0002] A switch cabinet is mainly a storage auxiliary device used for installing electrical control equipment in a power control system. For a switch cabinet, its sealing performance is a direct factor affecting the insulation effect between the internal equipment.

[0003] Currently, the Chinese utility model with the publication number CN215989986U discloses a sealing structure for a gas-insulated switch cabinet, including a cabinet body and a cabinet door. The cabinet door is located at the opening position of the cabinet body. An annular buckle groove plate is installed on the side wall of the cabinet door facing the cabinet body. An outer edge is provided at the opening position of the cabinet body, and the outer end of the outer edge is inserted into the annular buckle groove plate. A first rubber sealing ring is provided at the outer end of the outer edge. The cross-section of the first rubber sealing ring is U-shaped, and the side wall of the first rubber sealing ring facing the cabinet door is in an inclined state. By performing multiple sealing treatments on the switch cabinet, the diversity of the sealing method can be effectively improved, the sealing effect of the switch cabinet can be improved. At the same time, this sealing method is a contact-type sealing, and the internal extrusion pressure is relatively small, effectively avoiding deformation and damage of the sealing structure, improving the durability of its sealing, increasing the service life of the switch cabinet, and improving the practicability.

[0004] Currently, the sealing method between the cabinet door and the cabinet body of the existing switch cabinet usually uses an extrusion-type O-ring to seal the cabinet body and the cabinet door. Although the O-ring has a certain resilience, it will still deform due to extrusion or aging after long-term use, resulting in a decrease in the sealing performance of the switch cabinet and easy infiltration of moisture. Moreover, the cabinet door and the cabinet body of the switch cabinet cannot be self-locked and fixed. Therefore, the cabinet door is inconvenient to use, and it needs to be manually locked with the cabinet body after closing the cabinet door, with relatively low practicability.
