[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 objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention, but 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 drive mechanism 200 arranged on the base 100. In this embodiment, the drive mechanism 200 may be a conventional servo motor, and the base 100 There is also a rotating shaft 201, 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, and the rotating shaft 201 is provided with a first gear 202 and a clutch Specifically, the rotating shaft ...

The present invention relates to the technical field of power supply and distribution equipment, in particular to a clutch electric mechanism and an opening and closing operation method of an inflatable cabinet. The clutch electric mechanism of the present invention realizes the coupling of the clutch plate to the first gear by jacking up the clutch plate through a jacking block. The first gear meshes with the second gear to drive the operating shaft of the mechanism to rotate to realize the opening or closing operation, and the clutch plate is separated from the first gear after the rotating shaft reverses to ensure that the electric mechanism is completely separated from the operating shaft of the mechanism. The inflatable cabinet can also be operated manually; the operation method of the present invention delays for S seconds after the opening or closing operation, and the driving mechanism rotates in reverse to ensure that the clutch disc is completely separated from the first gear, and can reduce the When rapidly switching between forward rotation and reverse rotation, excessive back electromotive force may affect the motor and control circuit relay contacts, improving the stability and reliability of the mechanism.
Description
technical field [0001] The invention relates to the technical field of power supply and distribution equipment, in particular to a clutch electric mechanism of an inflatable cabinet and an opening and closing operation method. Background technique [0002] SF6 load switch inflatable cabinet is a load switch inflatable cabinet with sulfur hexafluoride gas insulation, which is widely used in high-voltage power supply system switchgear. During the maintenance period, the switch needs a series of operation procedures such as opening, power inspection, and hanging the ground wire before manual maintenance; the clutch motor mechanism of the traditional load switch inflatable cabinet has incomplete clutch between manual operation and electric operation. When the clutch synchronization is poor or the electric working power supply suddenly fails, the clutch system is stuck and other problems, which eventually lead to the failure of the manual operation system and the electric operati...
