Embodiment
[0014] The present invention includes a motor and an operating shaft; a mechanism box 2 is installed on the operating shaft 4, a motor 3, a transmission gear 9, a clutch gear 8, and a motor output gear 10 are installed in the mechanism box 2, and a moving shaft is installed on the operating shaft 4. Gear 1, the moving gear 1 meshes with the clutch gear 8, the clutch gear 8 is coaxial with the transmission gear 9, and the transmission gear 9 is connected with the motor 3 through the motor output gear 10. The left side of mobile gear 1 is provided with spring 6. The large operating shaft 4 is riveted together with the rotating shaft of the mobile gear 1 through an elastic cylindrical pin 5 . The motor speed is changed to achieve a suitable output torque. figure 1 , figure 2 and image 3 Both show the meshing state of the gears.
[0015] The end of the large operating shaft 4 is coaxially provided with a gear clutch mechanism 7 . No clutch required when electric.

The invention discloses an electric operation mechanism of a grounding switch of an intermediate and low voltage switch cabinet and aims at solving the problem that the electric operation, the transmission and the positioning of the grounding switch of the existing high voltage switch cabinet are inaccurate. The electric operation mechanism comprises a motor and an operation large shaft; a mechanism box is arranged on the operation large shaft; the motor, a transmission gear, a clutch gear and a motor output gear are arranged in the mechanism box, a moving gear is arranged on the operation large shaft, the moving gear is meshed with the clutch gear, the clutch gear is coaxial with the transmission gear, and the transmission gear is connected with the motor by the motor output gear. The electric operation mechanism has the advantages of small mechanism size, few transmission links, small energy loss, great transmission force moment, smooth transmission and the like, and the electric operation mechanism simultaneously improves the accuracy of the control on the transmission and the positioning, and also has the manual and the electric clutch functions.
Description
technical field [0001] The invention relates to an electric operating mechanism for a grounding switch of a medium and low voltage complete switch cabinet. Background technique [0002] The earthing switch is the main component of the switchgear, and occupies a very important position in the overall composition of the switchgear. In the past, the opening and closing operations of the grounding switch, the main component of the high-voltage and low-voltage complete switchgear in the switchgear, were all done manually by manpower. This operation method is not only time-consuming and laborious, but also not suitable for the operation mode of the intelligent switch cabinet circuit breaker handcart. [0003] At present, in the medium and low voltage switchgear, for the electric opening and closing operation of the earthing switch, domestic and foreign enterprises are in the research and development stage, and there are still few products that have been formed and used. The exis...
