Description
Technical field
The present invention relates to technical field indoor hv earthing switch, the indoor high-voltage warned in place more particularly to one kind is connect
Ground switch.
Background technique
The existing manual earthing switch of switchgear cannot generally be compatible with manual operation and electric operating simultaneously, wherein being manually operated
It whether in place to be closed a floodgate using travel switch induction, electric operating generally uses motor driven worm and worm gear, by worm and gear
Mechanism drives main axis, and the on/off switch movement speed of both operations is slow, unstable reliable and can interfere, and it is special to need
Switching mechanism can just exist simultaneously manual operation and electric operating.
103500671 B of Chinese patent CN discloses a kind of indoor high-voltage electric grounding switch, including static contact, dynamic touching
Head, main shaft, motor drive mechanism and pedestal, static contact are fixed on the base by insulator, and moving contact is fixed on master by connecting lever
On axis, main shaft both ends are movably arranged on pedestal, motor drive mechanism driving spindle be rotated such that moving contact and static contact connect or
It disconnects, is hinged between connecting lever and pedestal so that the spring that moving contact and static contact fast and stable are switched on or switched off.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, has many advantages, such as structure novel, splitting or integrating lock speed is fast and stablizes, with the manual earthing switch of existing switchgear
Mechanical interlocking, machine driving and installation dimension remain unchanged, electric operating be manually operated it is non-interference, do not need to switch,
Earthing switch ontology and operating mechanism integrated design.
But this kind of manual, electric integral switch is reached when closing a floodgate since electric power is insufficient 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 inconvenient to use.
And the switch is when in use, not in place due to closing a floodgate, and cannot directly arrive working condition, need manually to operate again, influence work
Make efficiency.And opening a sluice gate phenomenon not in place also will appear.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, that the present invention provides a kind of structures is simple, easy to maintain, closes a floodgate, opens
Lock working status indication in place, and is capable of the high reliability indoor hv earthing switch of rapid closing and separating brake.
The technical scheme adopted by the invention is that: the indoor hv earthing switch that one kind is warned in place, including pedestal, stationary contact
Head, moving contact, insulator, shaft and half I-shaped sliding rail rack, static contact are fixed by the bracket the top position in insulator,
And insulator is fixed on the top position on rear side of pedestal；Shaft is connected on pedestal, and half I-shaped sliding rail rack fixedly covers
In shaft；
The bottom of pedestal is equipped with boss portion, and boss portion is equipped with lower gear sliding rail, moving contact bottom towards insulator direction
It is connected in half I-shaped sliding rail rack and is moved up and down by gear sliding block, while corresponding to gear in half I-shaped sliding rail rack
Gear draw runner structure is equipped at the position of sliding block；
Gear slip front is connected in lower gear sliding rail by pull rod and sliding block and is moved forward and backward；
Sliding block drives it to move back and forth in lower gear sliding rail by either-rotation motor；The bottom position of gear sliding block is logical
It crosses returning spring and bushing bracket is connected to reciprocal telescopic movement in shaft；
The top position of moving contact is additionally provided with point contact type location switch, connection instruction at the top of the point contact type location switch
Lamp, the indicator light are connected to the top position of static contact；Point contact type location switch bottom it is triggered by a mandril
Switch, wherein mandril is fixed on the top position of moving contact.
Further, adjustable spring is also cased with outside pull rod.
Further, the spring outwards of adjustable spring are enclosed with rubber wear-resisting layer.
Further, gear sliding block is disc gear structure, and pull rod is connected to its top position by fixing axle
Set, so guarantee pull rod and gear sliding block relative position it is constant in the case where, sliding block can pull gear sliding block and
Moving contact slides up and down, final to guarantee moving contact and static contact combined floodgate or separating brake.
Further, moving contact is cylindrical structure, and the part for the static contact being in contact with it is square structure, in turn
Guarantee that moving contact and static contact have preferable contact effect at the time of contact.
Compared with prior art, the beneficial effects of the present invention are: indoor hv earthing switch of the invention, moving contact use
Upper and lower Double-gear sliding rail is steadily moved up and down in its stroke range by guaranteeing to control is moved back and forth to it, is had
There are preferable stability and reliability.And the structure is simple, reliable, and maintainability is preferable.Key improvements of the invention
Point is, is also connected with a point contact type location switch at the top of moving contact of the invention, which when in use, touches when dynamic
When head is completely attached to static contact, moving contact drives the mandril at the top of it to hold out against point contact type location switch, which opens its top
The indicator light in portion, instruction indoor hv earthing switch is in "on" position, in running order.
Indoor hv earthing switch of the invention drives sliding block in the lower gear of the boss portion of pedestal using either-rotation motor
It is moved back and forth in sliding rail, and then drives 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, open a sluice gate and the speed of separating brake uniformly, it is reliable, sudden will not disconnect or
Person closes, and the period of maintenance is longer, while service life is also longer, and indicating effect is good, avoids the maloperation of earthing switch.
