えも摩耗が発生する。 Such a closed gas-insulated high-voltage conductor arrangement is known from German Patent Application No. 2401093. In this type of device, the conductor is subjected to mechanical stress during operation due to electrical and thermal loads, which mechanical stress results in a relative movement between the conductor and the enclosure and is taken up by the supporting insulator. There must be. However, in general, the conductor is fixed at one support point and axial movement of the conductor is allowed at other support points so as not to impose additional loads on the supporting insulator. In this known device, the support insulator comprises an electrode which cylindrically surrounds the conductor, which electrode is formed as a sliding support and furthermore has a central recess in which a plate of electrically conductive material is inserted. A letter-shaped arcuate spring is arranged. This arcuate spring ensures the transmission of potential between the electrode forming the top of the support and the conductor carrying the high voltage. If the conductive contact between the conductor and the electrode is broken, a corona discharge may occur. This is prevented by the arcuate spring surrounding the conductor with obtuse angle legs and contacting the inner wall of the electrode and the conductor. In order to improve the sliding properties, in this known device each leg of the arcuate spring is provided with a contact piece made of graphite. This contact piece is relatively expensive and wear occurs not only during axial movement of the conductor during operation, but also during assembly of the conductor, when the conductor must be slid over the legs of the arcuate spring. .

が可能となる。 This purpose is based on this invention in a sealed gas insulated high voltage conductor device of the type mentioned above, in which the arcuate spring is provided with an outwardly projecting threaded part in its central part, and this threaded part is provided on the electrode. This is achieved by being at least partially inserted into the hole. This prevents the arcuate spring from rotating. The threaded part can be accessed from the outside of the electrode. In this way, the arcuate spring can be retracted into the recess of the electrode, for example by means of a screw tightening device that is screwed into the threaded part from outside the electrode, so that the insertion space for the conductor is freed up during the conductor assembly. This avoids friction between the conductor and the arcuate spring during assembly. Once the conductor assembly is completed, the screw tightening device is loosened and the arcuate spring contacts the outer surface of the conductor and the inner surface of the electrode due to its spring elasticity, so that the potential is completely transmitted and axial movement of the conductor relative to the electrode is possible. becomes.
