Description
Technical field
The present invention relates to a kind of method for being used to manufacture the container parts for sealed switchgear.
Background technology
It is used to manufacturing sealed switchgear known in the art and (such as is filled by the use of SF6 as insulating gas
Gas isolated medium voltage switchgear equipment) container parts method in, container parts are generally manufactured by pouring procedure so that
Sealed switchgear for distribution in medium and high pressure field is made up of this cast container.Typically, as
This materials'use aluminium.This sealed switchgear being made up of such aluminium vessel not only expends material but also cost is high
It is high.
The content of the invention
The technical problem to be solved in the present invention is to provide a kind of side for being used to manufacture the container parts of sealed switchgear
Method, this method cost in the case where pressure tolerance approximation is constant are cheap.
According to the present invention, above-mentioned technical problem manufactures the container of sealed switchgear by being used for of comprising the following steps
The method of part solves：
- by rolling sheet material and being welded along the butt joint edge of the sheet material rolled to construct cylindrical tube,
- flange is deflected into bending at least one tube end of the cylindrical tube.
Simply construct container parts by this method, the container parts can with using same method manufacture other
Container parts are bonded into sealed switchgear, wherein solid each other by potted component in flange made of cylindrical tube upper deflecting
Fixed or this container parts can be welded on other container portions in not flanged end for example on other container parts
On part.By using the method for simple sheet material, the cost compared with pouring procedure is cheap in the method in accordance with the invention and institute for institute
Need material less, this equally brings the cost advantage of this container parts.The deflection of flange under the application meaning is herein for such as
Lower method, wherein by two rollers on the cylindrical tube (itself is placed in rotation) being clamped on a slewing
Son, the roller of two rotations is set to act on tube wall, i.e. a roller is arranged on outside tube wall and a roller is arranged on tube wall
Inside, the roller of the two rotations is together around a point of rotation deflection herein so that in roller device relative to its raw bits
The tube wall of cylindrical tube is bent or also " can also referred to as deflect " and form flange when putting 90 ° of deflection.Deflection
Process herein can repeatedly be implemented or can also be implemented using the differently contoured of roller so that deflect a simple flange
Afterwards for example also can be by means of realizing thickening for Material reinforcement or flange with two roller devices.This deflection is thus
Ensure by simple and construct to diversity on this pipe or container parts of sealed switchgear in a manner of cost is cheap convex
Edge.
In another extension design of the present invention, perforate is set to sheet material before or after cylindrical tube is constructed, this
A little perforates are shaped to base by the method for axle journal processed (Aushalsen).By before or after cylindrical tube is formed in plate
Perforate is set by punching press or by Laser Processing, can for example to realize in a straightforward manner in material：Formed cylindrical tube it
Base is formed by the process of axle journal processed in these tappings afterwards so that thus can also be formed for sealed switchgear
Compact T-shaped container parts and cross container parts for switchgear.To the axle processed of base on container parts
Neck is carried out in this way herein, i.e. a substantially elliptical molding part is stretched or is extruded through in cylindrical tube
Existing perforate, wherein the major semiaxis of ellipse is more than the diameter of perforate so that base is formed by stretching or extrusion process.
Then another container parts, such as the pipe of the flange with welding could be welded in a straightforward manner on this base,
It is not provided with welding on the end of flange.
In another preferred embodiment of the method according to the invention, other perforates are set in sheet material, with
In airtightly fixed switchgear component.By setting other perforates can be easily in the sheet material for be processed to container parts
By other switchgears, as being airtightly fixed on container parts formed thereby such as penetration piece, switch contact, such as pass through
Welding, soldering or bonding etc..
Moreover, it relates to a kind of sealed switchgear, it has at least two container parts, and it utilizes basis
Method described in one of above-described embodiment manufactures, it is characterised in that is set between the flange of two container parts and passes through branch
The O-ring seals of carrier ring fixing, for airtightly sealing.
This sealed switchgear be simple to manufacture and cost is cheap because using above-mentioned manufacture method manufacture container
Part and the gas-tight seal of O-ring seals held between the flange of these container parts by means of support ring can use
The cheap component of cost, the stability and voltage endurance capability of Simultaneous Switching equipment are also enough.
Brief description of the drawings
The present invention is illustrated in more detail below by accompanying drawing and with reference to the embodiment of appended accompanying drawing.In the accompanying drawings：
Fig. 1 shows the manufacture of the container parts for sealed switchgear；
Fig. 2 shows the manufacture of another container parts for sealed switchgear；And
Fig. 3 shows the manufacture of the cross container parts for sealed switchgear.
Embodiment
Fig. 1 shows the sheet material 1 of the container parts for manufacturing sealed switchgear, by it in first method step
Cylindrical tube 2 is rolled into, the cylindrical tube is welded at butt joint edge 3.It is then convex by deflecting composition at first end 4
Edge 5.Therefore, cylindrical tube 2 is fixed in slewing and rotated around its axis.By two also around its axis
The roller arrangements of rotation are on the cylindrical tube 2 so that one in two rollers reclines the outside of cylindrical tube 2 and another
Abut in inside it.The two rollers are arranged and then outwards produced around a common point of rotation herein deflectablely
90 ° so that flange 5 is formed at the first end 4 of cylindrical tube 2.The thickness and profile of flange 5 herein can be by repeatedly weighing
Profile that is multiple or changing the two rollers accordingly changes so that can also pass through what the method constituent material of deflection strengthened
Flange.
Fig. 2 shows another housing parts 6 in distinct methods step.Sheet material 7 has perforate 8,9,10 and 11, this
A little perforates are being opened in sheet material 7 before sheet material 7 is rolled into cylindrical tube 12, such as pass through stamping procedure.Sheet material 7 is rolled
It is pressed into cylindrical tube 12 and is welded at butt joint edge 13.In ensuing method and step, flange 14 and 15 is by above
The deflection method of description is arranged at the end 16 or 17 of cylindrical tube 12.In ensuing method and step at perforate 8 or 9
Base is shaped by axle journal processed, wherein, cylindrical tube 12 clamps within one device and extrudes or draw by perforate 8 or 9
A circular molding part is stretched, so that base 18 or 19 shapes from perforate 8 or 9.Therefore other housing parts 6 can be used as and use
Used in the matrix of the cross container parts of sealed switchgear, wherein as reference picture 3 is visible, wherein in pipe
At seat 18 or 19 for example weld upper container part 20 or 21, and container parts 20 or 21 are for example as described with reference to fig. 1
Manufacture like that.Other forms of flanged pipe 22 or other container parts of the form of penetration piece 23 or 24 or the form of grounding contact 25 can
To be airtightly fixed on other housing parts 6, such as pass through welding, soldering or bonding so that meet exhausted in sealed gas
Requirement in terms of the pressure-bearing of the switchgear of edge.
Can simply and inexpensively it be manufactured for sealed switchgear, for example using manufacture method recited above
For gas isolated medium voltage switchgear equipment or the compact container part of high-tension switch gear, it is typically with SF6As insulation
Gas is filled, because may be constructed compact-sized and airtight container in the case where using less material, it is in its flange
Place seals each other by the O-ring seals held by support ring and airtightly connected.
