Background technology
The existing manual earthed switch of switch cubicle typically can not compatible manually operated and electric operating simultaneously, wherein manually operated
Whether in place to be closed a floodgate using travel switch sensing, electric operating typically drives worm and worm gear using motor, by worm and gear
Mechanism drives main axis, and the on/off switch responsiveness of both operations is slow, unstable reliable and can interfere, it is necessary to special
Switching mechanism could have manually operated and electric operating simultaneously.
The B of Chinese patent CN 103500671, disclose a kind of indoor high-voltage electric grounding switch, including static contact, dynamic touch
Head, main shaft, motor drive mechanism and base, static contact are fixed on base by insulator, and moving contact is fixed on master by connecting lever
On axle, main shaft two ends are movably arranged on base, motor drive mechanism drive shaft be rotated such that moving contact and static contact connect or
Disconnect, be hinged between connecting lever and base so that the spring that moving contact is switched on or switched off with static contact fast and stable.The indoor height
Press electric ground switch splitting or integrating lock use same spring bistable scheme, realize electric or hand operation axis rotate through in after
Quick splitting or integrating is switched, splitting or integrating lock speed fast and stable the advantages of, with existing switch cubicle manual earthed switch novel with structure
Mechanical interlocking, machine driving and installation dimension keep constant, electric operating with it is manually operated it is non-interference, need not switch,
Earthed switch body and operating mechanism integrated design.
But manually, electrically integral switch, when closing a floodgate, is reached this kind due to electric power deficiency or either-rotation motor failure
Less than the purpose closed a floodgate or opened a sluice gate, while the combined floodgate and to open a sluice gate structure complex, later period maintenance and in-convenience in use.
It is not in place due to closing a floodgate and the switch is when in use, it is impossible to directly to working condition, it is necessary to manually operate again, to influence work
Make efficiency.And phenomenon not in place is opened a sluice gate also to occur.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, the invention provides one kind it is simple in construction, easy to maintenance, close a floodgate, open
