Abstract
The contact structures that are used for the classification selector of staged transformer have a bar, and it is arranged in the hole of the cylindrical wall of making by reeling exhausted δ material, and there is a joint face one side and there is a contact-making surface another side.The bar of contact is provided with two insulating material sleeves that intermesh, and they are enclosed within on the bar from the cylindrical wall both sides, and each insulating material sleeve has a flange that raises up and adjoins mutually with cylindrical wall.Its contact-making surface is closely leaning against insulating material as electrode configuration and putting of crowned, and this contact remains on cylindrical wall by the crushed element that forms on the bar that is arranged in the cylindrical wall outside.
Description
The present invention relates to the contact structures that classification is selected that are used for by claim 1 preamble.Such contact structures are known in DRP DE-AS1118860.
Insulating material garden tube by the fibre technology manufacturing in the diversity switch of staged transformer not only is used for the load transfer switch but also is used for the classification selector.Therefore must on such insulating material garden barrel, dispose a plurality of contacts.At this moment must consider on the barrel of insulating material garden, rod member to be set, particularly under the situation of electric power impact load, high discharge electric field strength can occur thereon as electrode.So the contact that is arranged on the wall is equipped with additional lateral isolation.The high discharge electric field strength that should avoid whereby being occurred may directly appear on the glass fibre that is sectioned by the hole and on the capillary around single fiber.Also have at contact and avoid fixing means fixedly the time as far as possible, preventing the dielectric strength between contact additionally being reduced, so the unusual costliness of described this contact structures by the fixing means of metal with metal.
Task of the present invention provides the contact structures according to claim 1 preamble, and it can be made with simple mode, the field distribution deterioration of having avoided the fixing means of metal and having been caused, and required for this reason additional control electrode.This invention task is solved by the given technical scheme of the characteristic of claim 1.
In addition, these new contact structures just can be made with simple tools or supplementary means.Important in addition advantage shows: contact fixing is without metal-ware and also need not there be the screw thread of sharpened edge promptly can finish on wall.
Insulating material sleeve in these two sleeve shaped is fashionable, between this two insulating part, reserve a slit, exhaust duct with suitable mode makes slit and exterior, and when this had just been avoided in the classification selector being placed the grease chamber of transformer into, the place had air cushion at contact.
When contact often had the bar of garden shape and the terminal block that suppresses, it has such advantage: the insulating material sleeve in the terminal block side often had two notches opposite one another, and it has the width corresponding to terminal block.This with regard to facilitation the assembling of contact device, this insulating material sleeve can move on on the bar after contact plate is pressed into again, and then half-twist
When medium voltate particularly has the contact device of high request, to the bar of contact in the scope of two insulating material sleeve in addition the thin layer of high dielectric strength insulating material be suitable.Thus this bar can be for example with special insulating material looping or as with melting the in addition coating of insulating material of groove technology.
This in addition contact structures can directly be equipped with a common bucking electrode in joint side, and this bucking electrode can be arranged in this wise: it is clamped in simply between insulating material sleeve and contact deformation place and is adjoined with the upper surface of insulating material sleeve.This insulating material sleeve can also further be equipped with the annular flange flange that also outwards stretches around bucking electrode from the side, sets up an insulation shielding therefrom.
This new contact structures have a plurality of embodiment to show in the accompanying drawings, and are described in detail below.These accompanying drawings are:
Fig. 1: the first embodiment perspective cutaway view;
Fig. 2 a and 2b: with the vertical section and the cross section (local figure) of Fig. 1 same structure;
Fig. 3 a and 3b: the vertical section of second embodiment and end view;
Fig. 4 a and 4b: a kind of vertical section and cross section (local figure) with the supplementary insulation structure;
Fig. 5 a and 5b: a kind of vertical section and cross section (local figure) with shield electrode structure;
Fig. 6 a and 6b: a kind of vertical section and cross section (local figure) with bucking electrode and supplementary insulation structure.
By Fig. 1,2a and 2b can find out a contact in the wall 2 that is inserted in an insulating material garden tube, and it has the bar 1 of flat sheet.This contact has a contact-making surface that constitutes as electrode configuration 3 and a joint face that constitutes as flat link 4 is arranged in the garden tube outside in tube inboard, garden.In shaft 1 arranged around two insulating material sleeves 5,6 are arranged, their connections that intermeshes, the outer insulating material cover adjoins with the inboard and the outside of wall 2 respectively with flange 8 interior insulating material sleeve 5 mutually with flange 7.This contact closely is embedded in the insulating material sleeve 5 as the contact-making surface that electrode configuration 3 constitutes with it, encloses by its crushed element 9 on the other hand to lean against the bar other wall outside and overlap 6 layouts along outer insulating material, remains in this wise in the wall 2 of insulating material garden tube.There is slit 11 5,6 of two insulating cases, through exhaust duct 12 and exterior.Two holes that can see 13 help the distortion at the bar 1 in barrel 2 outsides, insulating material garden.When contact device was installed, it was one suitable but unshowned in the drawings instrument is finished distortion thus to insert in these holes.
Press Fig. 3 a and 3b, contact has the bar 31 of garden shape, and it is arranged in the insulating material garden barrel 2, and the inside butt end 33 of formation contact-making surface is made electrode form and is close on the interior insulating material sleeve 35.There is a spade tip that is pressed into 34 outer end of contact, and it surpasses the width of bar 31 and protruding.Correspondingly on the insulating material sleeve 36 two notches 361 are arranged outside therewith, it is corresponding to the width of spade tip 34.Before spade tip 34 was pressed into, insulating material sleeve 35 had been enclosed within on this contact in this, can slide by spade tip after this so outer insulating material overlaps 36, and then rotate about 90 degree.Equally, contact is fixed by deformation place 39, and deformation place 39 forms on wall 2 outboard beam 31.Like this so that 35,36 one of this contact and this two insulating material sleeves remain on reliably in the wall 2 of insulating material sleeve.Exhaust duct 312 is equally also arranged here.
An embodiment shown in Fig. 4 a and the 4b as at Fig. 1, represent among 2a and the 2b with explanation like that.The supplementary insulation 14 in the scope of two insulating material sleeves 45 and 46, formed of the bar 41 of contact here by the high dielectric strength insulating material.All the other are then identical with previous embodiment.
Fig. 5 a and 5b have added a bucking electrode 15 to starting described embodiment, and it is arranged around crushed element 9 ground.This bucking electrode 15 adjoins mutually with the upper surface of outer insulating material cover 6, and keeps by crushed element 9 equally.
Fig. 6 a and the 6b embodiment that to be another in essence described as earlier figures 1 and Fig. 2 a, 2b, but its outer insulating material cover 66 has an annular flange flange 16, this flange 16 are from the side around this bucking electrode 15 and outwards stretch.This flange is as additional insulation shielding.Remaining feature is consistent with feature described in Fig. 1,2a and 2b.
