Abstract

The utility model discloses a high voltage switchgear secondary plug interlocking device comprising a bending rod, a bending plate, a secondary interlocking installation rack, a secondary interlocking connecting plate, and a secondary interlocking hanging plate. The secondary interlocking hanging plate is connected with the secondary interlocking plate, and one end of the secondary interlocking connecting plate is fixedly provided with the bending plate. One end of the bending rod is connected with the bending plate, and a rear end of the bending plate is connected with the secondary interlocking installation rack. When a handcart is swung into a working position, an upper panel can be used to push the secondary interlocking hanging plate, and the bending plate is driven by the secondary interlocking hanging plate to rotate the bending plate, therefore the bending plate can be buckled with a secondary plug position, the secondary plug on the working position cannot be detached, and the misoperation can be prevented. The high voltage switchgear secondary plug interlocking device can be used to prevent the misoperation that a user forgets to take down the secondary plug of the handcart of the switchgear on the working position.

Description

The high-tension switch cabinet secondary-plug interlocking device
Technical field
The utility model relates to the high-tension switch cabinet technical field, relates in particular to a kind of high-tension switch cabinet secondary-plug interlocking device.
Background technology
Element in high-tension switch cabinet, more and more higher to product technology and interlocking requirement of shelter, for high-voltage switch cubicle handcart formula circuit breaker, owing to there is no special secondary interlock, usually design is all less reasonable, some will be issued to its purpose in the prerequisite of changing circuit breaker cart, brings a lot of unnecessary troubles to handcart, gives the uniformity and the many unreliabilities of increase that routinize of product.
The utility model content
For the problems referred to above, the purpose of this utility model is to provide a kind of high-tension switch cabinet secondary-plug interlocking device, to solve the problem of prior art.
To achieve these goals, the technical solution of the utility model is as follows:
The high-tension switch cabinet secondary-plug interlocking device, it is characterized in that, comprise knee, bent plate, secondary interlocking installing rack, secondary interlocking connecting plate, secondary interlocking link plate, described secondary interlocking link plate is connected with the secondary interlock plate, one end of secondary interlocking connecting plate is fixedly connected with bent plate, one end of knee is connected on bent plate, the rear end connecting secondary interlocking installing rack of bent plate.
In a preferred embodiment of the present utility model, also comprise the secondary interlock bracket, the secondary interlock bracket is connected with the secondary interlock plate, is provided with back-moving spring between secondary interlock plate and secondary interlock bracket.
Handcart shakes behind the service position, and top panel promotes secondary interlocking link plate, makes the bent plate rotation to fastening the secondary-plug position under the drive of secondary interlocking link plate.So just can reach secondary-plug and prevent from being removed in the service position, produce misoperation, the utility model can prevent that the handcart of service position switch cubicle from forgetting and take off secondary-plug and cause operation.
The utlity model has following characteristics:
1, simple in structure, easy to operate.
2, practical, materials processing is convenient.
3, can quantize to produce, cost is low.
4, plasticity is strong, can adjust the position according to handcart difference top panels and handcart stroke.
Characteristics of the present utility model can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained to be well understood to.
Description of drawings
Fig. 1 is schematic diagram of the present utility model.
The side schematic view of Fig. 2 Fig. 1.
Fig. 3 is bowing to schematic diagram of Fig. 1.
Fig. 4 is use view of the present utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, further set forth the utility model below in conjunction with specific embodiment.
Referring to Fig. 1,2,3 and 4, the high-tension switch cabinet secondary-plug interlocking device, comprise knee 1, bent plate 2, pin 3, secondary interlocking installing rack 4, secondary interlock bracket 5, secondary interlocking connecting plate 6, spring 7, secondary interlocking link plate 8, described secondary interlocking link plate 8 is connected with secondary interlock plate 6 by tapping screw M6, one end of secondary interlocking connecting plate 6 is fixedly connected with bent plate 2 by pin 3, one end of knee 1 is connected on bent plate 2, and the rear end of bent plate 2 is by pin connecting secondary interlocking installing rack 4.Secondary interlock bracket 5 is connected with secondary interlock plate 6 by pin, is provided with back-moving spring 7 between secondary interlock plate 6 and secondary interlock bracket 5.
At last integral body is fixed by screws on framework.
During use, handcart shakes behind the service position, and top panel promotes secondary interlocking link plate 8, makes bent plate 2 rotations to fastening the secondary-plug position under the drive of secondary interlocking link plate 8.So just can reach secondary-plug and prevent from being removed in the service position, produce misoperation, the utility model can prevent that the handcart of service position switch cubicle from forgetting and take off secondary-plug and cause operation.
Above demonstration and described basic principle of the present utility model, principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification is principle of the present utility model; the utility model also has the changes and improvements of various operating conditions under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed scope of the present utility model.The protection range that the utility model requires is defined by appending claims and equivalent thereof.
