Description
Technical field
The present invention relates to a kind of moveable high-voltage switchgear valve rival car interlocking gear.
Background technology
In the existing moveable high-voltage switchgear, the charged maintainer's of jeopardizing of contact life safety when avoiding overhauling, all be provided with valve rival car interlocking gear in switch cubicle, this interlocking gear generally includes connecting lever, linkage that is installed on the cabinet and the valve that has snap close; The equal pin joint in the middle part of every connecting lever is on cabinet, and the one end is provided with bearing pin, and this bearing pin cooperates with the guiding skewed slot of being located at handcart one side, and the other end then connects with the snap close on the valve by linkage.Handcart forces the connecting lever swing by guiding skewed slot and bearing pin in the process that advances or withdraw from, drive snap close release and locking by linkage then.
Yet the shortcoming of existing above-mentioned this interlocking gear is that the structure of linkage and valve snap close is comparatively complicated, and parts are more; And because only acting on the valve snap close, linkage can't open valve on the other hand along band, so when ordering about in the handcart push-on switch cabinet after linkage unties snap close, also must further advance the moving contact that makes on the handcart circuit breaker to back down valve can finish with touching of fixed contact and close, the switch of valve is inconvenience comparatively, operates comparatively loaded down with trivial details.
Summary of the invention
The present invention seeks to: provide a kind of simple in structure, and easy operating, especially valve moveable high-voltage switchgear valve rival car interlocking gear flexibly.
Technical scheme of the present invention is: a kind of moveable high-voltage switchgear valve rival car interlocking gear comprises the valve, connecting lever and the linkage that are installed on the cabinet; The middle part pin joint of described connecting lever is on cabinet, and the one end is provided with pivot pin, and this pivot pin cooperates with the guiding skewed slot of being located at handcart one side, and the other end connects with linkage; It is characterized in that described valve comprises an end pin joint on cabinet, and upper and lower two loose-leaf system door-plates that the other end is connected by sliding shackle; Described linkage then comprises two L type support arms, and the equal pin joint in middle part of every L type support arm is on cabinet; One end of two L type support arms flexibly connects with the end that sliding shackle is set on upper and lower two loose-leaf system door-plates respectively, the other end then simultaneously pin joint at an end of connecting lever.
Being provided with chute described in the present invention in the cabinet slides for upper and lower two sliding shackles.
And chute further is arranged vertically described in the present invention, pin joint is at an end of two active section arms respectively for an end of described two L type support arms simultaneously, and the other end of these two active section arms is then respectively with the end pin joint that sliding shackle is set on the upper and lower loose-leaf system door-plate.
Every loose-leaf system door-plate is formed by connecting by loose-leaf pin by two substrates described in the present invention, and wherein an end pin joint of a substrate is on cabinet, and an end of another piece substrate then is provided with sliding shackle, should hold the end flexible connection with L type support arm simultaneously.
Connecting lever described in the present invention and the linkage that cooperates with connecting lever have two covers, are symmetrically arranged in both sides in the cabinet respectively.
The present invention is when work, and handcart can advance in cabinet or withdraw from prior art is the same, and to specific service position and test position should be arranged.When handcart is advanced to the process of service position from test position, pivot pin on the connecting lever is movable under the guiding of handcart guiding skewed slot, thereby driving connecting lever pivots, and with this towards two L types of valve direction ejection support arm, make two L type support arms movable up and down respectively, thereby push two loose-leaf system door-plates open, untie sliding shackle, valve is opened, and finished the handcart moving contact of breaker simultaneously and close with interior the touching of fixed contact of valve.Otherwise, when handcart is withdrawn into the process of test position from the service position, pivot pin on the connecting lever is reverse activity under the guiding of handcart guiding skewed slot, thereby drive connecting lever around the axle reverse rotation, and spur two L type support arms with this, make two L type support arms movable in opposite directions, thereby close up two loose-leaf system door-plates, pin sliding shackle, valve is closed.
Advantage of the present invention is:
Among the present invention owing on valve, adopt sliding shackle, so compared to existing technology, its linkage need not to directly act on the release that snap close just can be finished valve; Simplified the structure of integral body of the present invention greatly.
Among the present invention owing to directly push valve open, so simplified operation by linkage; And because valve adopts upper and lower two loose-leaf system door-plates, add further in cabinet, to be provided with the chute that slides for the sliding shackle on the loose-leaf system door-plate, make that the unlatching of valve is more flexible, improved the functional reliability of integral body of the present invention greatly.
