Abstract
The utility model discloses a grounding switch and rear door interlocking device for a high-voltage switch cabinet, which comprises a grounding switch operating shaft and a rear door interlocking shaft. The grounding switch and rear door interlocking device is characterized in that the grounding switch operating shaft and the rear door interlocking shaft are vertically parallel and respectively provided with a connecting crank arm, the connecting crank arms are connected with each other by the aid of a connecting rod, and the rear door interlocking shaft is connected with a rear door interlocking device arranged on a rear door. By the aid of the technical scheme, the grounding switch and rear door interlocking device thoroughly solves the problem of insufficient insulation distance between a rear door interlocking shaft and an electrified body (copper bar) so that potential safety hazards are eliminated, and is flexible and reliable in transmission and convenient in installation.
Description
Technical field
The utility model relates to the high-tension switch cabinet field, specifically a kind of high-tension switch cabinet earthed switch and back door interlocking device.
Background technology
Will accomplish " five is anti-" in the operating process of high-tension switch cabinet: 1, the vacuum circuit-breaker dolly in the high-tension switch cabinet is after test position is closed a floodgate, and the dolly circuit breaker can't enter the service position.Ground connection cutter in (prevent on-load from closing a floodgate) 2, the high-tension switch cabinet is when closing, and the dolly circuit breaker can't advance to close a floodgate.Vacuum circuit-breaker in (preventing to close a floodgate with earth connection) 3, the high-tension switch cabinet coils machinery and the locking of cabinet door on the usefulness ground connection cutter of cabinet back door when combined floodgate work.Vacuum circuit-breaker in (preventing mistakenly entering charged chamber) 4, the high-tension switch cabinet closes a floodgate when work, and splice grafting ground cutter can't drop into.When the vacuum circuit-breaker in (preventing charged hanging earthing conductor) 5, the high-tension switch cabinet closes a floodgate operation in work, can't withdraw from the service position of dolly circuit breaker.(preventing on-load broaching tool lock).For reaching above-mentioned requirements, must be provided with the mechanical interlocks that prevents misoperation between handcart, circuit breaker, earthed switch and the rear cabinet door.
The earthed switch of high-tension switch cabinet needs operating axis to operate, but the back door interlocking shaft that links with the earthed switch operating axis because and the earthed switch operating axis be on an axis, so caused the insulation distance between back door interlocking shaft and the electrified body (copper bar) not enough, general 10KV standard will reach more than the 125mm, and has only 97.5mm at present, existing solution is to add insulating sleeve on electrified body (copper bar), but this method is also unreliable, the very easy Electrical Safety accident that causes.
The utility model content
The purpose of this utility model proposes a kind of high-tension switch cabinet with earthed switch and back door interlocking device just at above-mentioned deficiency of the prior art, thoroughly solves the not enough problem of insulation distance between back door interlocking shaft and the electrified body (copper bar).
In order to achieve the above object, the utility model adopts following technical scheme:
High-tension switch cabinet earthed switch and back door interlocking device, comprise earthed switch operating axis and back door interlocking shaft, described earthed switch operating axis and back door interlocking shaft be arranged in parallel up and down, be respectively arranged with on described earthed switch operating axis and the back door interlocking shaft and be connected connecting lever, be connected to each other by a connecting rod between the described connection connecting lever, described back door interlocking shaft is connected with back door interlocking device on being located at the back door.
Described earthed switch operating axis is set in parallel in the top of the earthed switch of high-tension switch cabinet, and described back door interlocking shaft is set in parallel in the below of the earthed switch of high-tension switch cabinet, and described connection connecting lever is vertically set on the side of the earthed switch of high-tension switch cabinet.
Described connecting rod with described be connected between the connecting lever mutually hinged.
External force is transmitted earthed switch by the earthed switch operating axis, is grounded the normal divide-shut brake of switch, and the earthed switch operating axis passes to back door interlocking shaft realization and back gate interlock with external force by connection connecting lever, connecting rod again in addition.
By technique scheme, the utility model thoroughly solves the not enough problem of insulation distance between back door interlocking shaft and the electrified body (copper bar), and its ensuring smooth transmission is reliable, and is easy for installation.
Description of drawings
Fig. 1 is a structural representation 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, below in conjunction with concrete diagram, further set forth execution mode of the present utility model.
As shown in Figure 1, high-tension switch cabinet of the present utility model earthed switch and back door interlocking device, comprise earthed switch operating axis 1 and back door interlocking shaft 2, described earthed switch operating axis 1 and back door interlocking shaft 2 be arranged in parallel up and down, described earthed switch operating axis 1 is set in parallel in the top of the earthed switch 6 of high-tension switch cabinet, described back door interlocking shaft 2 is set in parallel in the below of the earthed switch 6 of high-tension switch cabinet, be respectively arranged with on described earthed switch operating axis 1 and the back door interlocking shaft 2 and be connected connecting lever 3, described connection connecting lever 3 is vertically set on the side of the earthed switch 6 of high-tension switch cabinet.Be connected to each other by a connecting rod 4 between the described connection connecting lever 3, described connecting rod 4 is connected between the connecting lever 3 mutually hingedly with described, and described back door interlocking shaft 2 is connected with back door interlocking device 5 on being located at the back door.
Its course of work is as follows: external force passes to earthed switch 6 by earthed switch operating axis 1, be grounded the normal divide-shut brake of switch 6, simultaneously, external force is by rotation earthed switch operating axis 1, drive and connect connecting lever 3 rotations, thereby connect connecting lever 3 again drivening rod 4 move up and down and drive connection connecting lever 3 rotations of being fixed on the back door interlocking shaft 2, back door interlocking shaft 2 rotates together under the drive that connects connecting lever 3 and realizes the interlocking of back door interlocking device 5 and earthed switch 6.
More than show 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; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
