Abstract

This utility model discloses a frequency converter control cabinet with a PLC, including a cabinet body, anti-collision plates, a safety door, and a fan duct. Support legs are installed at the four corners of the bottom of the cabinet body. A safety door is hinged to the front face of the cabinet via built-in hinges. A fan duct is installed at the center of the top of the cabinet body. This utility model features anti-collision plates on both sides of the cabinet body, connected to the safety plates by springs. When the anti-collision plates are impacted, an alarm light will sound, increasing the safety of the internal components. Furthermore, the fan at the top of the cabinet body provides cooling for the internal components. A lifting frame is installed at the lower part of the cabinet interior. By controlling a drive motor, the threaded cylinder rotates, allowing the lifting frame to be used as needed. When the cabinet needs to be moved, controlling the lifting frame causes the casters to contact the ground, and the support legs to lift off the ground, thus enabling the cabinet to move. This design is convenient to operate and highly efficient.
