Description
Technical field
The present invention relates to technical field indoor hv earthing switch, more particularly to self-locking formula indoor high-voltage ground connection is opened
Close.
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.
The content of the invention
In order to overcome the above-mentioned deficiencies of the prior art, and can the invention provides one kind is simple in construction, easy to maintenance
The high reliability indoor hv earthing switch of rapid closing and separating brake.
The technical solution adopted in the present invention is：Self-locking formula indoor hv earthing switch, including it is base, static contact, dynamic
Contact, insulator, rotating shaft and half I-shaped sliding rail rack, static contact are fixed on the tip position of insulator by support, and
Insulator is fixed on the tip position on rear side of base；Rotating shaft is connected on base, and half I-shaped sliding rail rack, which is regularly enclosed on, to be turned
On axle；
The bottom of base is provided with boss portion, and boss portion is provided with lower gear slide rail towards insulator direction, and moving contact bottom passes through
Gear sliding block is connected in half I-shaped sliding rail rack and moved up and down, while correspondence gear sliding block in half I-shaped sliding rail rack
Position at be provided with gear draw runner structure；
Gear slip front is connected in lower gear slide rail by pull bar and sliding block and moved forward and backward；
Sliding block drives it to be moved back and forth in lower gear slide rail by either-rotation motor；The bottom position of gear sliding block is by returning
Multiple spring and bushing support are connected to reciprocal telescopic movement in rotating shaft.
Further, also it is cased with adjustable spring outside pull bar.
Further, the spring outwards of adjustable spring are enclosed with rubber wear-resisting layer.
Further, gear sliding block is disc gear structure, and pull bar is connected to its top position by fixing axle
Put, and then in the case where ensureing that pull bar and gear sliding block relative position are constant, sliding block can pull gear sliding block and
Moving contact is slided up and down, final to ensure that moving contact closes a floodgate or separating brake with static contact.
Compared with prior art, the beneficial effects of the invention are as follows：The indoor hv earthing switch of the present invention, moving contact is used
Upper and lower Double-gear slide rail to it by carrying out moving back and forth control, it is ensured that is stably moved up and down in its forming range, has
There are preferable stability and reliability.And this is simple in construction, reliable, and maintainability is preferable.
The indoor hv earthing switch of the present invention, sliding block is driven in the lower gear of the boss portion of base using either-rotation motor
Moved back and forth in slide rail, and then drive gear sliding block and moving contact to move up and down, and then realize the conjunction of moving contact and static contact
Lock or opening.The high voltage ground switch of the structure, is opened a sluice gate and the speed of separating brake is uniform, reliable, sudden will not disconnect or
Person closes, and the cycle of maintenance is longer, while service life is also longer.
