[0002] The SF6 load switch inflatable cabinet is a load switch inflatable cabinet insulated by sulfur hexafluoride gas. It is widely used in high-voltage power supply system switchgear. In order to ensure the reliable operation of the switch, the operation and maintenance of the high-voltage switch has certain operating procedures to protect personnel During the maintenance period, the switch needs a series of operations such as opening, testing, and grounding before manual maintenance can be performed; the clutch electric mechanism of the traditional load switch inflatable cabinet has incomplete clutch between manual operation and electric operation , poor clutch synchronization or sudden failure of the electric working power supply, the clutch system is stuck and other problems, which eventually lead to accidents where both the manual operating system and the electric operating system fail, seriously affecting the reliable operation of power equipment

Embodiment Construction
[0026] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0027] refer to Figure 1 to Figure 4 The shown electric clutch mechanism of an inflatable cabinet includes a base 100 and a driving mechanism 200 arranged on the base 100. In this embodiment, the driving mechanism 200 can be a conventional servo motor, and the base 100 A rotating shaft 201 is also arranged on the top, and the rotating shaft 201 is connected with the driving mechanism 200 through gear meshing or a conventional reducer. The driving mechanism 200 can drive the rotating shaft 201 to rotate on its own. The rotating shaft 201 is provided with a first gear 202 and a clutch. Assemblies, ...

The invention relates to the technical field of power supply and distribution equipment and particularly relates to a gas insulated switchgear clutch electric mechanism and an opening-closing operation method. According to the clutch electric mechanism, a clutch disc is jacked up through a jacking block so that the clutch disc is combined with a first gear, the first gear is engaged with a secondgear to drive a mechanism operating shaft to rotate to realize switching-off or switching-on operation, and the clutch disc is separated from the first gear after the rotating shaft rotates reverselyso that thorough separation of the electric mechanism and the mechanism operating shaft is guaranteed, and manual operation of the inflation cabinet can be realized in case of failure. According to the operation method provided by the invention, switching-off or switching-on operation is realized, and the driving mechanism rotates reversely after delaying for S seconds, so the clutch disc is completely separated from the first gear, the influence on the motor and a relay contact of a control loop possibly caused by overhigh counter electromotive force when the motor is rapidly switched betweenforward rotation and reverse rotation can be reduced, and stability and reliability of a mechanism are improved.
