Description
Technical field
The present invention relates to technical field indoor hv earthing switch, open more particularly to a kind of swing type indoor high-voltage ground connection
It closes.
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

Rotating motor rotation, and then drive vertical cam to rotate by actuating cam, finally drive vertical cutting ferrule and moving contact vertical direction
Rotation；
Wherein: being also connected with swing arm between vertical rocker arm middle part and the support slide unit of L-type pedestal；Swing arm one end is fixed on
On vertical rocker arm, the other end is swung in the sliding slot by being slidably disposed on L-type pedestal；
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, adjustable spring is also cased with outside swing arm.
Further, the spring outwards of adjustable spring are enclosed with rubber wear-resisting layer.
Further, moving contact is cylinder barrel shaped structure, and then guarantees that moving contact and static contact combined floodgate or when separating brake have
There are preferable fitting and separating effect.
Further, the part of static contact is square structure, so guarantee moving contact and static contact have at the time of contact compared with
Good contact effect.
Compared with prior art, the beneficial effects of the present invention are: indoor hv earthing switch of the invention, using shaft and
The vertical rocker arm of cam driven and moving contact matched with it moves straight up, while being tensioned vertical rocking bar using swing arm, suitably
Slow down for it, guarantee steadily to move up and down in its stroke range, there is preferable stability and reliability.And it should
Structure is simple, reliable, and maintainability is preferable.Key improvements point of the invention is, is also connected at the top of moving contact of the invention
One point contact type location switch, when in use, when moving contact and static contact full contact, moving contact drives it to the earthing switch
The mandril at top holds out against point contact type location switch, which opens the indicator light at the top of it, indicates at indoor hv earthing switch
It is in running order in "on" position.
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.
