Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 3,4, the invention provides a kind of central switch equipment lower door interlocking mechanism, it comprises: be connected the earthed switch operating axis 20 arranging, the large bent plate 22 of interlocking that is connected setting with guide rail interlocking 21, and the little bent plate 23 of the hard-wired interlocking of switch cabinet body 10, the door lock 25 that is installed on switch cubicle Xiamen 24 and release bent plate 26 with earthed switch, described earthed switch operating axis 20 is provided with can be with the limiting plate of its rotation 27; The large bent plate 22 of described interlocking can move up with the guide rail 21 torsion spring power effects of interlocking, and the large bent plate 22 of this interlocking is provided with two groups of combination bore; The little bent plate 23 of described interlocking is provided with the interlocking latch 28 through two limit, between this interlocking latch 28 and the little bent plate 23 of interlocking, is provided with the first stage clip 29, and interlocking latch 28 other ends are inserted in switch cabinet body 10; Described door lock 25 correspondences are provided with axle sleeve 30, and this axle sleeve 30 rotates with door lock 25, and axle sleeve 30 inside are provided with the second stage clip 31; Combination bore on the large bent plate 22 of described interlocking matches with interlocking latch 28 and axle sleeve 30, to realize Xiamen 24 switch on request.The present invention drives limiting plate 27 to depress the large bent plate 22 of interlocking of combination bore by earthed switch operating axis 20, and the combination bore of interlocking on large bent plate 22 coordinates with interlocking latch 28 and axle sleeve 30, realizes Xiamen 24 switch on request.The present invention contrasts in prior art and plants by more than 20 the interlocking device that parts form, and has clear superiority simple in structure, easy for installation.
As shown in Figure 5, as a kind of specific embodiment of the present invention, the large bent plate of described interlocking 22 lower ends are provided with two groups of combination bore, and one group is circle bar combination bore 32, and another group is size combinations cylindrical void 33.
As shown in Figure 6,7, axle sleeve 30 one end in the present invention are the circumscribed body 34 of circular shaft parallel edges, and these axle sleeve 30 middle parts are provided with ring-shaped step 35, and axle sleeve 30 other ends are that the shape circular shaft inner corresponding with door lock 25 cut body 36.Wherein, the circular shaft that this axle sleeve 30 is inner corresponding with door lock 25 is cut body end and is provided with an endoporus 37, and this endoporus 37 is equiped with the second stage clip 31.
Further, as a kind of selectivity embodiment of the present invention, the little bent plate 23 of described interlocking is shaped as U-shaped, and interlock two parallel edges of little bent plate 23 of this U-shaped are provided with through hole, and interlocking latch 28 passes from this hole.In the specific embodiment of the invention, described interlocking latch 28 is ledge structure, and this interlocking latch 28 is shape small in ends broad in the middle.Interlock little bent plate 23 in conjunction with the aperture on switch cabinet 10, can realize interlocking latch 28 is carried out to position limitation.
Central switch equipment lower door interlocking mechanism of the present invention, it is specially adapted in the lower door interlocking mechanism of GZS1 switchgear.In the time that earthed switch operating axis 20 drives earthed switch to close a floodgate, limiting plate 27 rotates with earthed switch operating axis 20, depress the large bent plate 22 of interlocking, the circular hole height of the large bent plate 22 circle bar combination bore 32 of this interlocking is corresponding with axle sleeve 30, now rotate door lock, can safe opening Xiamen 24, interlocking latch 28 ejects under the first stage clip 29 effects simultaneously, the ledge structure of this interlocking latch 28 with the large bent plate 22 of interlocking in same facade.When earthed switch closes a floodgate, under 24 open modes of Xiamen, now this central switch equipment lower door interlocking mechanism can be interlocked by rival car (not shown), prevents that handcart from entering into service position from test position, ensure that cable compartment is not charged, ensure personal safety.
When under 24 openings of Xiamen, grounding misoperation switch makes its separating brake, limiting plate 27 is no longer pushed down the large bent plate 22 of interlocking, the large bent plate 22 of interlocking moves up under guide rail is interlocked 21 torsion spring active forces, above moves to size combinations cylindrical void 33 lower ends and interlocking latch 28 ledge structure corresponding positions are carried out spacing.The circular hole height of the large bent plate 22 circle bar combination bore 32 of now interlocking is not corresponding with axle sleeve 30, can not close Xiamen 24.This kind of situation, the earthed switch that must again close, could separate earthed switch after cutting out Xiamen 24, can ensure operating personnel's mistakenly entering charged chamber, has higher reliability.
Further, as a preferred embodiment of the present invention, described release bent plate 26 one end are provided with the pilot hole (not shown) of trough of belt, the other end is fixed on 24 inside, Xiamen by a release screw 38, these release bent plate 26 middle parts are provided with round bar combination bore, the bar hole dimension of this circle bar combination bore is slightly larger than the annular small stair at axle sleeve 30 middle parts, and is less than large step, and the circular hole size of this circle bar combination bore is slightly larger than large step.In addition, Xiamen 24 of the present invention is also provided with a bar hole 39, and this bar hole 39 is for installing or restriction release screw 38.
When switchgear, there was a mechanical failure, when after earthed switch can not close a floodgate or earthed switch closes a floodgate, the large bent plate 22 of interlocking can not limited plate 27 be depressed, the circumscribed body 34 of circular shaft parallel edges of axle sleeve 30 is corresponding with the height and position of the large bent plate 22 circle bar combination bore 32 of interlocking, door lock 25 can not drive axle sleeve 30 to rotate, and Xiamen 24 cannot be opened.Therefore, this kind of next emergency release that needs of situation, opens Xiamen 24 and overhauls with switching devices.When central switch equipment lower door interlocking mechanism emergency release of the present invention, first unscrew release screw 38 and depress to bar hole 39 lower ends, release screw 38 drives release bent plate 26 to move down, the circular hole height of the round bar combination bore at release bent plate 26 middle parts is corresponding with axle sleeve 30, axle sleeve 30 is separated by the second stage clip 31 active forces and door lock 25, the do not interlocked constraint of large bent plate 22 circle bar combination bore 32 of door lock 25, Xiamen 24 is that cocoa is opened.Seen from the above description, compared to GZS1 lower door interlocking mechanism of the prior art, not only structure is comparatively simple, processing and manufacturing is easy for installation, reliably higher for central switch equipment lower door interlocking mechanism of the present invention, and its emergency release program is also comparatively simple, operates very convenient and swift.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
