Abstract
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
The present invention relates to a kind of mesolow voltage switchgear earthed switch motor-operating mechanism.
Background technology
Earthed switch is the main element of switchgear, occupies considerable status in the overall formation of switchgear.Branch, the closing operation of the major component earthed switch of high and low pressure voltage switchgear in switch cubicle all was to be finished by the manpower manual operation in the past.This mode of operation is not only time-consuming, effort, more is not suitable for the operator scheme of intelligent switch board breaker handcart.
At present, in the mesolow switchgear, for electronic branch, the closing operation of earthed switch, enterprise is in development both at home and abroad, and the product of use of shaping is also less.Existing high-tension switch cabinet earthed switch motor drive mechanism is to adopt chain-wheel mechanism, and what put control usefulness in place is travel switch, and the weak point of this mechanism is transmission, the control that puts in place is inaccurate.
Summary of the invention
The purpose of this invention is to provide a kind of mesolow switch cabinet grounding switch motor-operating mechanism, to solve existing mesolow switch cabinet grounding switch electric operating and the transmission inaccurate problem that puts in place.
The present invention includes motor, operation macro-axis; On described operation macro-axis, mechanism case is installed, motor, travelling gear, clutch gear, motor output gear are installed in the mechanism case, on the described operation macro-axis carrier wheel is housed, carrier wheel and clutch gear engagement, clutch gear is coaxial with travelling gear, and travelling gear links to each other with described motor by motor output gear.
The present invention has advantages such as mechanism's volume is little, and transmission link is few, and energy loss is little, and the driving force distance is big, and driving force is steady, the accuracy that has improved transmission simultaneously, put in place and control.Also has manual, electronic clutch function.

Embodiment
The following examples can make those skilled in the art more fully understand the present invention, but do not limit the present invention in any way.
Embodiment
The present invention includes motor, operation macro-axis; On operation macro-axis 4, mechanism case 2 is installed, motor 3, travelling gear 9, clutch gear 8, motor output gear 10 are installed in the mechanism case 2, on the operation macro-axis 4 carrier wheel 1 is housed, carrier wheel 1 and clutch gear 8 engagements, clutch gear 8 is coaxial with travelling gear 9, and travelling gear 9 links to each other with motor 3 by motor output gear 10.The left side of carrier wheel 1 is provided with spring 6.Operation macro-axis 4 is fitted together by the rotating shaft riveting of elastic cylindrical pin 5 with carrier wheel 1.Motor is by speed change, to reach suitable power output distance.Fig. 1, Fig. 2 and Fig. 3 show the gear meshing state.
The coaxial gears to engage and disengage mechanism 7 that is provided with in end of operation macro-axis 4.Do not need clutch when electronic.
During work, motor 3 rotates by motor output gear 10 driven gears 9, and the clutch gear 8 coaxial with gear 9 also and then rotates, and clutch gear 8 is meshed with carrier wheel 1, so just rotation of carrier wheel 1, the operation macro-axis 4 of earthed switch is also along with rotation.
When not adopting electric operating function or electric operating disabler, when using original manually operated function, operating grip is operated on the macro-axis 4 from gears to engage and disengage mechanism 7 along the left among Fig. 3 to being inserted into, gears to engage and disengage mechanism 7 will promote carrier wheel 1 vertically the left in Fig. 3 move, make the carrier wheel 1 and clutch gear 8 clutches that are meshed, the operation macro-axis of operating grip direct control earthed switch rotates, be grounded the branch closing operation of switch, promote carrier wheel 1 by spring after operation is finished and reset, recover engagement.
