By bevel gear in being linked between drive rod one end in casing, drive rod one end outside casing is stretched out in the cabinet
In vitro；There is quarter butt in the gangbar, one end and the gangbar of quarter butt are in be fixedly connected, and longitudinal centre line and the linkage of quarter butt
The axis perpendicular of bar, the other end of quarter butt is hinged with connecting rod, and the other end of connecting rod is hinged on the restrictor bar through bottom half
Middle part.In use, passing through external handle or the overhanging end of other aid rotation of drive rod, it is possible to drive gangbar to turn
It is dynamic, while driving quarter butt to swing up and down rotation around the axis of gangbar, so that on-load switch is lifted or reduced by connecting rod
Restrictor bar so that division above and below the lock realization of on-load switch.Quarter butt in this solid loop-net cabinet is turning to peak or minimum
During point, it is necessary to the rotation of drive rod is limited by other auxiliary bodies, and then the rotation of quarter butt is limited indirectly, to keep this
When restrictor bar opening and closing state, be otherwise easy to the phenomenon for occurring tripping.And the structure of these auxiliary bodies is generally all relatively more multiple
Miscellaneous, manufacture and maintenance cost are also higher.
The content of the invention
The problem to be solved in the present invention is to provide a kind of solid loop-net cabinet of on-load switch linkage mechanism, this solid ring
Net cabinet is less prone to tripping operation, and its on-load switch link gear is simple in construction, and manufacture and maintenance cost are relatively low.
To solve the above problems, taking following technical scheme：
The solid loop-net cabinet of the on-load switch linkage mechanism of the present invention includes having insulating cylinder body in cabinet, cabinet, insulate
There is on-load switch in cylinder.The on-load switch includes restrictor bar, and one end of restrictor bar is hinged on the outlet rod of insulating cylinder body.It is described
Have to have on casing, a side wall of casing above insulating cylinder body and have drive rod in through hole, through hole, in rotation between drive rod and through hole
Coordinate.Have gangbar in the casing, the two ends of gangbar are rotating between the respective side wall of casing respectively, gangbar with
Drive rod is perpendicular, and is in be linked by bevel gear between drive rod one end in gangbar and casing, outside casing
Drive rod one end is stretched out outside the cabinet.There is quarter butt in the gangbar, one end and the gangbar of quarter butt are in be fixedly connected, and
The longitudinal centre line of quarter butt and the axis perpendicular of gangbar, the other end of quarter butt are hinged with connecting rod, and the other end of connecting rod is passed through
Bottom half is hinged on the middle part of the restrictor bar.It is characterized in the corresponding quarter butt one end of connecting rod case relative with the through hole
Compression spring mechanism is connected between the middle part of body sidewall.
Wherein, the compression spring mechanism includes outer barrel and inner cylinder, the internal diameter of outer barrel is more than the external diameter of inner cylinder, and inner cylinder is opened
Mouth end is stretched into outer barrel, and has compression spring between the intracavity bottom of outer barrel and the intracavity bottom of inner cylinder；The closing of the outer barrel
In cooperation is hinged between the middle part of the end wall box relative with through hole, the blind end of inner cylinder and one end of quarter butt are in be hinged cooperation.
Further improvement of the present invention scheme is that the insulating cylinder body includes body, and body has inner chamber, and it is by insulating materials
It is made.The upper end of the body is opening-like, and vertical through holes are arranged at its bottom, the intracavity inter-connection of the vertical through holes and body.Institute
Stating on a side wall of body has wire outlet seat, and wire outlet seat has cross through hole, the intracavity inter-connection of the cross through hole and body, described
Outlet rod is located in the cross through hole.There is baffle plate between side wall where the vertical through holes and cross through hole, baffle plate is in body
Integrally connected.The relative baffle plate one side equal undulate from top to bottom of the relative inner body wall of the cross through hole, cross through hole,
So that this body sidewall, the equal indention in the cross section in the baffle plate face.There is observation panel on this body sidewall above the wire outlet seat.
The insulating cylinder body replaces plane of the prior art using corrugated curved surface on inner body wall, baffle plate, in creep age distance requirement
In the case of identical, its whole height is relatively low, small volume, is conducive to transporting and installs, while can also reduce solid loop-net cabinet
Height and volume.
Such scheme is taken, with advantages below：
Due to having insulating cylinder body, insulating cylinder body in the cabinet of the solid loop-net cabinet of the on-load switch linkage mechanism of the present invention
Inside there is on-load switch, on-load switch includes restrictor bar；Having above insulating cylinder has drive rod and gangbar, gangbar in casing, casing
It is perpendicular with drive rod, and between drive rod one end in gangbar and casing by bevel gear in being linked；Have in gangbar
Quarter butt, one end and the gangbar of quarter butt are in be fixedly connected, and the longitudinal centre line and the axis perpendicular of gangbar of quarter butt, quarter butt
The other end be hinged with connecting rod, the other end of connecting rod is hinged on the middle part of the restrictor bar through bottom half, and connecting rod is corresponding
Compression spring mechanism is connected between the middle part of quarter butt one end wall box relative with the through hole.When the quarter butt is turned to most
When high point or minimum point, the compression spring decrement in compression spring mechanism is smaller or does not have；When quarter butt is moved from high point to middle part
It is dynamic or from low spot to middle part move when, the decrement of compression spring gradually increases, and the resistance that drive rod is rotated is larger；When quarter butt by
When middle part is to high point or low spot movement, the decrement of compression spring is gradually reduced, and drive rod rotates non-resistance.Therefore, the solid
On-load switch link gear in ring main unit, when lock is in separating brake or "on" position, is pressed when carrying out divide-shut brake control
The effect of contracting spring thrust, quarter butt position will not be moved, i.e., the restrictor bar position of on-load switch keeps constant, it can be ensured that occur without jump
The phenomenon of lock.Meanwhile, the structure of compression spring mechanism is relatively simple, and manufacture and maintenance cost are relatively low.
