1results about How to "Extended operating time" patented technology

This utility model relates to the field of power equipment technology and discloses a heat dissipation box for a terminal of a power distribution automation station. The box includes a distribution box with a door rotatably connected to its side wall, a rain shield fixedly connected to its upper surface, a cooling fan inside, a dustproof component on its side wall, and a movable component inside. The movable component includes a sliding frame, and a slide rail is fixedly connected inside the distribution box. In this utility model, when electrical components need to be installed or maintained, the operator moves a lever to compress a first spring and move the locking pin out of the slide rail, releasing the sliding frame and allowing the mounting plate position to be adjusted along the slide rail. After adjustment, releasing the lever causes the first spring to push the locking pin back into the slide rail slot, re-fixing the sliding frame. This solves the problems of fixed mounting plate position and inconvenient component installation and maintenance in traditional distribution boxes, shortening operation time.
