Description
Technical field
A kind of adjustable bus bridge of switchgear is the utility model is related to, belongs to equipment for power transmission and distribution field.
Background technology
In power transmission and transformation system, switchgear is its important part, for realizing the conveying of electric energy and distribution, and
The important ring that bus bridge frame conduct, switchgear and transformer connect, after the completion of switch cubicle installation and debugging, surveyed according to scene
Take measurements making processing, delivery date is typically more urgent, therefore the convenience and controllability of crane span structure design, directly influences and is
System it is punctual, reliably put into operation.
Due to the aerial side such as bus bridge contact, cable outlet between inlet wire, cabinet of ac metal closing switch gear generally use
Case.Because site foundation error is larger, after switch cubicle installs, the two mounting bridge switch cabinets that should face, B phases have one
Individual deviation, and due to reasons such as installation inclinations, measurement error is in positive and negative 2cm or so.Usual bus bridge uses stationary structure,
The scene of often resulting in can not install.Substantial amounts of scene is done over again or remake production, causes larger economic loss and input
The construction delay of operation.
To solve the above problems, Publication No. CN203103875U discloses a kind of telescopic bus bridge of switchgear,
Between two sections of pontics plus an expansion plate is connected, and four waist holes are opened on expansion plate and are used to adjust, the measurement on elimination of level axial direction misses
Installation deviation problem caused by difference.
Although above-mentioned telescopic bridge solves the fine setting on length direction, it the defects of be：Can not solve build bridge two
When the not parallel either two switch cubicle B phases of platform switch cubicle have installation deviation or natively unequal two switch cubicle width of bridge formation,
Radial missing needs installation question during regulation.
The content of the invention
To be solved in the utility model is existing bus bridge because the construction and installation of length direction measurement error and radial direction are inclined
The problem of scene is not easy to install caused by difference.
In order to solve the above problems, the utility model provides a kind of adjustable bus bridge of switchgear, including left bridge
The bridge pier of body, right pontic and the left and right sides, it is characterised in that bridge set, the left bridge are provided between the left pontic and right pontic
Body, the connection end of right pontic are moveable in bridge set；Bridge set bottom, which is provided with, to be used to install insulator and overlaps the adjustable of copper bar
Insulator beam, outside of the bridge set wherein on diagonal pontic adjacent thereto are connected by rotary seal trigger structure；The rotation
Turn the axillare that shrouding mechanism includes being flexibly connected with bridge set, axillare is led to by rotating shaft connection rotating plate, flap pontic adjacent thereto
Lock-screw is crossed to be fixedly connected.
Preferably, the junction that the rotary seal trigger structure covers with pontic or bridge is provided with suspension ring.
It is highly preferred that the suspension ring are covered by lock-screw with bridge and axillare is connected.
Preferably, the bridge is put is provided with access panel provided with access panel, access panel.
Preferably, the pontic of the corresponding side in inner chamber of the bridge set is engaged.
Bridge set is molded the square sleeve that is welded by high-strength steel plate, as the support field after left pontic and the insertion of right pontic
Institute.The short transverse of bridge set will ensure that left and right pontic can be inserted smoothly, and width is greater than left pontic and right pontic each B phases
To the width on side, along with the alternate deviations of two bridge B, then widen an adjustable clearance and be used to adjust radial measurement error (between corresponding
Clearance angle point installs a set of rotary seal trigger structure, for blocking gap).Bridge puts and (is welded with locking nut in correspondence position) to be equipped with and hangs
Ring, bridge applies mechanically suspender and hangs suspension ring, adjustment height to the horizontal flush position of bridge pier, locking lifting suspension ring during installation.Left pontic and
Right pontic is respectively from left and right insertion bridge set, it is possible to achieve the regulation of length direction and radial direction, after adjusting correct position, and locking
The lock-screw of bridge set above and below is in left pontic and the corresponding part of right pontic.Bridge set top is provided with overhauls window, for installing
Insulator and copper bar.Access panel is opened, (is welded in bridge set bottom) on installation insulator to adjustable insulator beam, then peace
Dress overlap joint copper bar, connects left pontic and the copper bar at right pontic both ends.After the completion of cover detection window cover plate, tightening screw.
Rotary seal trigger structure covers both sides diagonal position by axillare by being articulated in bridge, while flap is by being articulated in axillare
On, both freely rotates, and can conveniently block bridge set and the gap between left pontic or right pontic.Rotation makes the two sealing symbol
Close after requiring, the plastics lock-screw being bolted on flap is screwed, respectively at left pontic and the correspondence position up and down of right pontic.
The utility model have the advantages that it is easy to operate, be easily installed, adjustable extent it is wide, be especially suitable for left and right pontic
Though bridge formation situation that is wide, wide not parallel or parallel but having dislocation.
Compared with prior art, the beneficial effects of the utility model are：
1st, this adjustable bus bridge is applied widely, has both solved length direction measurement error, solves two bridge formation switch cubicles again
Width is inconsistent, tilts or when B phases misalign, installation question caused by the deviation of radial direction.
2nd, this adjustable bus bridge bridge set is that high-strength steel plate is molded the square sleeve that is welded, left pontic and right pontic point
Not Cha Ru in bridge set, while realize length axially and width radial direction smooth adjustment, solve solid caused by in-site measurement and construction
There is error.
3rd, due to using locking mode, installation reliability height are easy for installation simultaneously up and down.
4th, rotary seal trigger structure, there are a fixed rotating shaft M and a movable rotating shaft N, can be realized while rotating flat
It is dynamic, it can flexibly block bridge set and the space between left pontic or right pontic.
5th, the present invention can simplify crane span structure design, for the wide bridge formation situation of both sides switch cubicle, left and right pontic and left and right bridge
Pier can be made equally, improve standardization and delivery cycle, significant for delivery date original nervous bus bridge.
