The utility model solves the technical scheme that its technical problem adopts:
A kind of interlock being applied to switchgear, comprise fixed head, described fixed head is fixed on mechanism's cover of switchgear by the bending at its upper and lower two ends, be provided with some guide blots and be convenient to carry out high-voltage switch gear the handle hole of breaking-closing operating, described fixed head is provided with left skateboard, right slide plate by guide blot, wherein said left skateboard, right slide plate all independently can move back and forth under the guiding of described guide blot, and the two realizes the locking to described handle hole in different left cunnings and right sliding collocation process.
As the improvement of technique scheme, described left skateboard and right slide plate are provided with some chutes, and all independently can move back and forth within the scope of described trough width under the guiding of described guide blot.
As the improvement of technique scheme, described handle hole is divided into sub-switching operation hole and closing operation hole, and when left skateboard and the equal left side of right slide plate slide to extreme position, described sub-switching operation hole can normal running, and described closing operation hole is locked; When left skateboard and the equal right side of right slide plate slide to extreme position, described closing operation hole can normal running, and described sub-switching operation hole is locked; When a left skateboard left side slide to extreme position and the guide blot of right slide plate be positioned at its chute centre position time, described sub-switching operation hole and closing operation hole all locked.
As the improvement of technique scheme, described fixed head lower end is provided with lower skateboard by guide blot, and described lower skateboard lower end is fixed with the guide rod for locked described switchgear.
The beneficial effect that the utility model brings has:
This interlock structure is simple, easy and simple to handle, it is by the slip matched combined of left skateboard and right slide plate, and Appropriate application space of components position relationship realizes the interlocking of switching devices divide-shut brake, this interlock not only possesses higher reliability, requires (to prevent by mistake point, close circuit breaker for the electric equipment such as high-voltage switch gear meets " five prevent " simultaneously; Prevent on-load from dividing, close isolating switch; Prevent band cable address (conjunction) earth connection (earthed switch); Prevent band ground wire power transmission; Prevent mistakenly entering charged chamber) provide sound assurance.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail,
Accompanying drawing 1 is preferred embodiment structural front view of the present utility model;
Accompanying drawing 2 is preferred embodiment structure side views of the present utility model;
Accompanying drawing 3 is another example structure schematic diagrames of the present utility model.
Embodiment
With reference to accompanying drawing 1 and accompanying drawing 2, the utility model is a kind of interlock that can be applicable on switchgear or other high voltage electric equipments, can be fixed in use on equipment cabinet, be realized the interlocking of switching devices by the combination of himself structure.
Concrete, this interlock comprises fixed head 1, fixed head 1 is as its structural substrate, by the bending 11 at its upper and lower two ends can be fixed on switchgear mechanism cover on, namely cover on spring mechanism, simultaneously fixed head 1 is provided with some guide blots 12 and is convenient to carry out high-voltage switch gear the handle hole of breaking-closing operating, and specifically can be divided into sub-switching operation hole 13 and closing operation hole 14.
As the implementation structure of interlock, left skateboard 2 and right slide plate 3 are all installed on fixed head 1 by guide blot 12, some chutes 5 are provided with simultaneously, can under the guiding of guide blot 12 both making, independently move back and forth in the width range of chute 5, and in the right sliding anabolic process of different left cunnings, realize the locking to handle hole by the two, such as:
When all a left side slides to extreme position for left skateboard 2 and right slide plate 3, now sub-switching operation hole 13 can normal running, and closing operation hole 14 is because of locked by stopping; When all the right side slides to extreme position for left skateboard 2 and right slide plate 3, now closing operation hole 14 can normal running, and sub-switching operation hole 13 is because of locked by stopping; When left skateboard 2 left side slides to extreme position, the guide blot 12 of right slide plate 3 is positioned at its chute 5 centre position, now then sub-switching operation hole 13 and closing operation hole 14 all locked.
Simultaneously, the trend of chute 5 can be not limited to horizontal direction, the chute 5 being arranged at vertical direction can make slide plate independently move back and forth along vertical direction equally, and by horizontal space displacement and vertical space displacement, or the matched combined of vertical space displacement and vertical space displacement realizes interlocking effect of the present utility model, concrete with reference to accompanying drawing 3.
In addition, lower skateboard 4 is installed by guide blot 12 in fixed head 1 lower end, and be fixedly installed guide rod 41 in the lower end of lower skateboard 4, lower skateboard 4 arranges vertical chute 5, when nature, because of should in extreme position bottom by Gravitational sliding plate 4, now can by dead for switchgear cabinet door lock with coordinating of switch cabinet by guide rod 41.
This interlock structure is simple, easy and simple to handle, it is mainly by the slip matched combined of left skateboard 2 with right slide plate 3, and Appropriate application space of components position relationship realizes the interlocking of switching devices divide-shut brake, this interlock not only possesses higher reliability, requires (to prevent by mistake point, close circuit breaker for the electric equipment such as high-voltage switch gear meets " five prevent " simultaneously; Prevent on-load from dividing, close isolating switch; Prevent band cable address (conjunction) earth connection (earthed switch); Prevent band ground wire power transmission; Prevent mistakenly entering charged chamber) provide sound assurance.This interlock is integrated with the closing locking of switch, separating brake locking, the locking of cable cabinet door, reliable in quality, safety, integration degree is higher, and this device volume is less, installation and removal can be carried out in less spatial dimension, save labour costs and time cost.
It should be noted that, the above is preferred embodiment of the present utility model, and the utility model is not limited to above-mentioned execution mode, as long as it reaches technique effect of the present utility model with identical means, all should belong to protection range of the present utility model.
