Description

Technical Field

[0002] In recent years, with the rapid development of subway construction, the use of tunnel ventilation fans has maintained a rapid growth trend. Since subways are mostly located in enclosed underground spaces, ventilation and fire safety issues require special attention. Traditional environmental control cabinet ventilation circuits are generally assembled from materials such as signal indicator lights, electrical buttons, gear knobs, signs, fuses, intermediate relays, contactors, mounting plates, wires and cables, character tubes, and spiral wound tubes. This process occupies a large space, and workshop workers need to connect each individual component with wires and cables according to specific electrical logic. The assembly process is complex, and the large number of components makes troubleshooting difficult, time-consuming, and labor-intensive if a fault occurs. Utility Model Content
