るので、前記の接触装置は非常に高価に形成される。In a tap changer for a tap transformer, an insulating cylinder made by the filament method is used for both the on-load changer and the tap selector. Therefore, it is necessary to arrange a large number of contact pieces on this kind of insulating cylindrical wall. In this case, the shaft seated through the hole in the insulating cylinder wall acts as an electrode and produces a high exit electric field strength mainly when subjected to an electric shock load. The contact pieces seated on the wall therefore have additional transverse insulation. This should avoid that high exit electric field strengths occur directly on the glass fibers interrupted by the holes and possibly on the capillaries formed around the individual filaments.
In order not to reduce the electrical stability between the contact pieces by this metal fixing means, it is necessary to avoid the metal fixing means as much as possible when fixing the contact pieces. Formed very expensive.

単な方法でつくることを課題とする。SUMMARY OF THE INVENTION The present invention provides a simple method for a contact device according to the preamble of claim 1 which leads to a worsening of the electric field conditions and thereby avoids metal fixing means which require additional control electrodes. The challenge is to make it.
（課題の解決のための手段） この課題は特許請求の範囲に記載された発明特定事項
によって解決される。(Means for Solving the Problem) This problem is solved by the invention specifying matters described in the claims.
新しい接触装置が簡単な工具又は補助手段によって作
られることができるという事実の他に絶縁材円筒壁への
接触片の固定が追加の金属部分なく、鋭利な縁のねじを
使用することもなしに行われることが他の重要な利点で
ある。Besides the fact that the new contact device can be made by simple tools or auxiliary means, the fixing of the contact piece to the insulating cylindrical wall is without additional metal parts and without the use of sharp-edged screws. What is done is another important advantage.
両絶縁材ブッシュの相互移動の際に両絶縁材ブッシュ
の間に隙間が残されているので、隙間を外部と連通する
通気ダクトが合理的な方法で形成される。こうして変圧
器の油室へのタップ選択器の挿入の際に接触片に空気ク
ッションが残ることが回避される。Since a gap is left between the two insulating bushes during the mutual movement of the two insulating bushes, a ventilation duct communicating the gap with the outside is formed in a rational manner. In this way, it is avoided that an air cushion remains on the contact piece when the tap selector is inserted into the oil chamber of the transformer.

組立を容易にする、そのわけは絶縁材ブッシュは接続フ
ィンの押潰し後にもシヤフトに被嵌されることができそ
の後に絶縁材ブッシュは90゜回転されればよいからであ
る。In the case of a contact piece with a round shaft and crushed connecting fins, it is advantageous if the insulating bushing located on the side of the contact fins has two opposite recesses corresponding to the width of the connecting fins. . This facilitates the assembly of the contact device, since the insulation bush can be fitted on the shaft even after the connection fins are crushed, after which the insulation bush only needs to be turned 90 °. is there.

ニングされることもできる。For contact devices which require the withstand of particularly high voltages, it is reasonable for the shaft of the contact piece to have a thin layer of electrically insulating material in the region of both insulating bushes. For this purpose, the shaft can be wound, for example, with special insulation or lined with insulation, for example by dip coating.
更に接続面側に通常の遮蔽電極を設けることも可能で

を備えることができる。Further, a normal shielding electrode can be provided on the connection surface side. The shielding electrode is simply clamped between the insulating bush and the shaft deformation, the shielding electrode being able to be arranged to abut the surface of the insulating bush. In this case, the insulating bush can grip the side surface of the shielding electrode and have a circular edge forming an insulating barrier (barrier) that opens outward.
