Abstract
A kind of high-voltage switch cabinet grounding switch operating mechanism interlock, comprise action bars, lock tube and bearing, action bars is through the cavity of bearing update bar, lock tube is provided with block, bearing is provided with mounting panel, be provided with the slide-bar that is parallel to each other and locking bar through bearing and mounting panel, the slide-bar located inside bearing and locking bar are provided with connected nail, slide-bar cover has spring, spring is between mounting panel and connected nail, and in initial condition, slide-bar stretches out doorframe, locking bar stretches out bearing, and the block on lock tube is attached to the end of locking bar.The utility model increases and the reverse interlocking at back door, and first must shut back door can operational grounding switch, and structure is simple, and reliability is strong, and anti-error performance increases greatly.
Description
Technical field
The utility model relates to a kind of interlocking device of switch cabinet, particularly relates to a kind of grounding switch operation interlocking device.
Background technology
" interlocking " of high-tension switch cabinet is the important measures ensureing power network safe operation, guarantee equipment and personal safety, prevent misoperation.Conventional structure as shown in Figure 1, for KYN28-12 grounding switch operation interlocking device schematic diagram, action bars is fixedly connected with lock tube, bearing is fixed on framework, this structure is without reverse interlocking function, back door is opened or do not opened can operational grounding switch, can cause the danger that staff gets an electric shock like this.
Utility model content
Technical problem to be solved in the utility model overcomes prior art defect, provides a kind of grounding switch operation interlocking device, and during to guarantee that back door is opened, earthed switch cannot operate.
The technical scheme that the technical problem that the utility model solves adopts is:
A kind of high-voltage switch cabinet grounding switch operating mechanism interlock, comprise action bars, lock tube and bearing, action bars is through the cavity of bearing update bar, it is characterized in that lock tube is provided with block, bearing is provided with mounting panel, be provided with the slide-bar that is parallel to each other and locking bar through bearing and mounting panel, the slide-bar located inside bearing and locking bar are provided with connected nail, slide-bar cover has spring, spring is between mounting panel and connected nail, and in initial condition, slide-bar stretches out doorframe, locking bar stretches out bearing, and the block on lock tube is attached to the end of locking bar.
During use, slide-bar and rear gate interlock, when opening below, slide-bar under the action of the spring, is in initial condition, because locking bar stretches out bearing, locking bar stretches out the end that seat part is divided into locking bar, and the block on lock tube is attached to the end of locking bar, the rotation of block restriction lock tube, such lock tube just can not rotate, and action bars also just can not have rotated.When back door is shut, back door withstands on slide-bar end, drive locking bar to move before cabinet simultaneously, locking bar end enters in bearing perforation, and the end of locking bar departs from the block on lock tube, and such lock tube is not subject to the restriction of locking bar, lock tube just can have rotated, action bars also can have rotated, can operational grounding switch, and this interlocking just can operate.
The beneficial effects of the utility model are: of the present utility model by the improvement to this interlock original, increase the reverse interlocking with back door, and first must shut back door can operational grounding switch, and structure is simple, and reliability is strong, and anti-error performance increases greatly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, utility model is further illustrated.
The structural representation of Fig. 1 prior art; Fig. 2 is that the utility model embodiment is at back door open mode schematic diagram; Fig. 3 is that the utility model embodiment is at rear door closure state schematic diagram; Fig. 4 be the utility model embodiment frameless time schematic side view; Fig. 5 is the structural representation of the utility model embodiment lock tube; Fig. 6 is the utility model embodiment lock tube plan structure schematic diagram.
In figure: 1, framework 2, back door 3, action bars 4, bearing 5, lock tube 6, spring 7, slide-bar 8, locking bar 9, screw rod 41, mounting panel 51, block.
Embodiment
In Fig. 1-Fig. 5, a kind of high-voltage switch cabinet grounding switch operating mechanism interlock, comprise action bars 3, lock tube 5 and bearing 4, action bars 3 is through the cavity of bearing 4 update bar 3, the outer wall of lock tube 5 is provided with block 51, bearing 4 is provided with mounting panel 41, be provided with the slide-bar 7 that is parallel to each other and locking bar 8 through bearing 4 and mounting panel 41, slide-bar 7 and locking bar 8 are parallel with action bars 3 respectively, the slide-bar 7 located inside bearing 4 and locking bar 8 are provided with screwed hole, screw rod 9 is fixed together screw rod 9 by the screwed hole of slide-bar 7 and locking bar 8 by slide-bar 7, slide-bar 7 cover has spring 6, spring 6 is between mounting panel 41 and screw rod 9, in initial condition, slide-bar 7 stretches out doorframe 1, locking bar 8 stretches out bearing 4, block 51 on lock tube 5 is attached to the end of locking bar 8.During use, interlock in slide-bar 7 and back door 2, when 2 open below, slide-bar 7, under the effect of spring 6, is in initial condition, because locking bar 8 stretches out bearing 4, locking bar 8 stretches out the end that bearing 4 part is locking bar 8, and the block 51 on lock tube 5 is attached to the end of locking bar 8, and block 51 limits the rotation of lock tube 5, such lock tube 5 just can not rotate, and action bars 3 also just can not have rotated.When back door 2 is shut, back door 2 withstands on slide-bar 7 end, drive locking bar 8 to move before cabinet simultaneously, locking bar 8 end enters in bearing 4 bores a hole, and the end of locking bar 8 departs from the block 51 on lock tube 5, and such lock tube 5 is not subject to the restriction of locking bar 8, lock tube 5 just can have rotated, action bars 3 also can have rotated, can operational grounding switch, and this interlocking just can operate.Of the present utility model by the improvement to this interlock original, increase the reverse interlocking with back door, first must shut back door can operational grounding switch, and structure is simple, and reliability is strong, and anti-error performance increases greatly.
Finally, it should be pointed out that above embodiment is only the more representational example of the utility model.Obviously, the utility model is not limited to above-described embodiment, can also have many distortion.Every above embodiment is done according to technical spirit of the present utility model any simple modification, equivalent variations and modification, all should think and belong to protection range of the present utility model.
