Description
Technical field
The present invention relates to technical field indoor hv earthing switch, more particularly to flatly moving type indoor hv earthing 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

It slides up and down together；
The top position of moving contact is additionally provided with point contact type location switch, connects indicator light at the top of point contact type location switch, refers to
Show that lamp is connected to the top position of static contact；Its switch is triggered by a mandril in point contact type location switch bottom, wherein mandril
It is fixed on the top position of moving contact.
Further, jacking block, which is located between the inner wall and moving contact of tip chute, further respectively has a damping spring, and
And one end of each damping spring is fixed on the tip chute side wall of jacking block, the other end of each damping spring is freely
It is overlapped on the side of moving contact.
Further, either-rotation motor is fixed on support slide unit by support, and push rod is horizontal along the direction of horizontal concrete chute
It is flexible, and then pull and perhaps push jacking block to move horizontally final to realize that moving contact is moved closer in vertical direction or far from quiet
Contact.
Further, it is additionally provided with inclination pull rod between the intermediate position and L-type pedestal of jacking block, is also cased with dimension outside inclination pull rod
Steady spring.
Further, the angle for tilting the vertical direction of pull rod and jacking block is 30-45 degree.
Compared with prior art, the beneficial effects of the present invention are: indoor hv earthing switch of the invention, uses two-way electricity
Machine drives push rod to move horizontally, and then jacking block is driven to move horizontally, so that realizing will be above and below the vertical sliding device at the top of jacking block
Mobile, vertical sliding device moves up and down, final that moving contact is driven to move up and down, thus realize high-voltage switch gear open a sluice gate and point
Lock.High voltage ground switch of the invention simultaneously, is respectively being arranged between the feeler lever of vertical sliding device in the tip chute of jacking block
One damping spring, while suitably slowing down the vibration that jacking block is transferred on moving contact, guarantee in its stroke range steadily
It moves up and down, there is preferable stability and reliability.And the structure is simple, reliable, and maintainability is preferable.
In addition, key improvements point of the invention also resides in, a point contact type is also connected at the top of moving contact of the invention and is arrived
Bit switch, when in use, when moving contact and static contact full contact, moving contact drives the mandril top at the top of it to the earthing switch
Tight point contact type location switch, the switch open the indicator light at the top of it, and instruction indoor hv earthing switch is in "on" position, locates
In working condition.
Indoor hv earthing switch of the invention, 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.
