AI Technical Summary

Technical Problem

The existing sealing structure of prefabricated substations is difficult to maintain a good sealing effect while ensuring that the door can be opened easily, which leads to the intrusion of dust and rainwater, affecting the life of components and safe operation.

Method used

The system employs a dual-sealing structure, which involves installing first and second sealing strips at the junction of the door and the body. A drive mechanism is used to engage the second sealing strip with the door for sealing, and a position detection device automatically controls the sealing process to ensure a good seal.

Benefits of technology

It achieves a stable seal between the box door and the box body, preventing dust and rainwater from entering, improving the sealing and protection effect of the box-type substation, and ensuring the safe operation of internal components.
