Abstract
Description
Technical Field
[0001] This utility model relates to the field of frame switch technology, and more specifically, to an inlet / outlet mechanism for a frame switch. Background Technology
[0002] A frame switch is a key electrical component widely used in power systems, industrial equipment, and automated control systems. Its main function is to perform connection, disconnection, and switching operations in circuits to ensure the safe operation of power systems and the efficient management of equipment.
[0003] Currently, most frame switches still rely on manual operation, meaning the switch is turned on and off by manually operating a handle. While this method is simple and direct, manual operation requires direct contact with the switch, posing certain safety risks, especially in high-voltage or high-current environments. Furthermore, manual operation is particularly difficult for switchgear installed at high altitudes or in confined spaces. Manual operation cannot meet the demands for rapid response, resulting in low operational efficiency and impacting the overall system operating efficiency.
[0004] With the rapid development of industrial automation and smart grids, higher demands are being placed on the ease of operation, safety, and intelligence of electrical equipment. As a key piece of equipment in the power system, the improvement of the operation method of frame switches is imperative. Utility Model Content

This structure is compatible with the internal structure of most existing frame switch bases, making it suitable for upgrading and retrofitting existing frame switchgear with low upgrade costs. Furthermore, this structure can also be applied to new frame switchgear.
[0009] Preferably, the rotation center of the main gear is located on the central axis of the rotating shaft.
[0010] Preferably, the rotary drive device is connected to the support frame; the top of the rotary drive device is at a lower level than the top of the support frame; this avoids collisions between the rotary drive device and the frame switch, ensuring that the frame switch can move in and out normally.
[0011] Preferably, the rotary drive device refers to a horizontal motor.

When switching to manual entry / exit, the rotary drive device can be set to the brake-off state, the operating handle can be connected to the manual operation position at the front end of the rotating shaft, and the rotating shaft can be rotated manually by rotating the operating handle to achieve the frame's entry / exit.
[0015] Preferably, the support frame includes side plates on the left and right sides, a front support module on the front side, and a rear support module on the rear side; the front support module and the rear support module are respectively provided with support holes for the rotating shaft to pass through.
