Description
Technical field
The present invention relates to technical field indoor hv earthing switch, more particularly to a kind of indoor high-voltage warned in place connects
Ground is switched.
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
Lock working condition is indicated in place, and is capable of the high reliability indoor hv earthing switch of rapid closing and separating brake.
The technical solution adopted in the present invention is：A kind of indoor hv earthing switch warned in place, including base, stationary contact

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 regularly covers
In rotating shaft；
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；
The tip position of moving contact is additionally provided with connection indicator lamp, institute at the top of point contact type location switch, the point contact type location switch
State the tip position that indicator lamp is connected to static contact；The point contact type location switch bottom is triggered it by a push rod and switched,
Wherein push rod is fixed on the tip position of moving contact.
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.
Further, moving contact is cylindrical structural, and the part for the static contact being in contact with it is square structure, and then
Ensure that moving contact has preferably contact effect with static contact when contacting.
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 stroke range, has
There are preferable stability and reliability.And this is simple in construction, reliable, and maintainability is preferable.The key improvements of the present invention
Point is, a point contact type location switch is also associated with the top of moving contact of the invention, and the earthed switch when in use, is touched when dynamic
When head is completely attached to static contact, moving contact drives the push rod at the top of it to hold out against point contact type location switch, and the switch opens its top
The indicator lamp in portion, indicates that indoor hv earthing switch is in "on" position, in running order.
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, indicating effect is good, it is to avoid the maloperation of earthed switch.
