Definitions
- Vacuum interrupter and switch pole The invention relates to a vacuum interrupter with a Ge ⁇ housing of at least one first metallic housing ⁇ flange, extends through which a first connection pin to a first contact of a vacuum-tight in the vacuum interrupter, at least one Isolierstoffgeophuse Scheme as well as a second terminal bolt, which to be a second contact vacuum-tight in the vacuum interrupter in ⁇ he stretches.
- Such a trained vacuum interrupter with the metallic housing part between the disc-shaped insulator and the further disk-shaped insulator is particularly advantageous for higher Bemes ⁇ sungshoven because a capacitive voltage distribution of the applied voltage with open contact system via the vacuum interrupter by the plurality of metallic housing parts and disc-shaped insulators so that the disc-shaped insulators must each isolate only a part of the applied voltage dielectrically.
- the disc-shaped insulator has undercuts in such a way that metal forming the switching process does not completely cover an inner surface of the disk-shaped insulator.
- FIG. 1 shows a vacuum interrupter according to the invention in a first embodiment
- FIG. 2 shows a vacuum interrupter according to the invention in a second embodiment
- FIG. 3 shows a vacuum interrupter according to the invention in a third embodiment
- FIG. 4 shows a vacuum interrupter according to the invention in a fourth embodiment
- Figure 5 shows an embodiment of a disc-shaped Iso ⁇ lators the vacuum interrupter according to the invention
- FIG. 6 shows another embodiment of a occnför ⁇ shaped insulator of the vacuum interrupter according to the invention.
- FIG. 7 shows an exemplary embodiment of a switch pole and
- the Isolierstoffgecouuse Scheme 6 in the form of the disc-shaped insulator has a radial wall thickness d, which is at least 1.5 times greater than the axial length L of the disc-like insulator, wherein preferably the thickness d is at least 2 times as large compared with the axial length L of the disk-shaped insulator.
- FIG. 3 shows the vacuum interrupter 21 of Figure 2, wherein like components are provided with the same reference numerals.
- the insulating material housing region 26 of FIG. 2 in the form of the disk-shaped insulator is replaced by a disk-shaped insulator 26 'in FIG. 3, wherein undercuts are provided as shielding elements 30', which are formed in such a way that an internal surface of the disk-shaped insulator 26 'is formed during the switching operation. can not completely cover, so that the insulating ability of the disc-shaped insulator 26 'is maintained inside the vacuum interrupter.
- a further metallic housing part 51 and a second insulating housing region 52 are provided between the first insulating housing region 46 and the second metallic flange 47, so that the vacuum interrupter 41 has a plurality of insulating housing regions with metallic housing parts arranged therebetween, wherein the insulating housing regions 46 and 52 Shield elements 53 and 54 are arranged wel ⁇ che the Isolierstoffgeophuse Schemee 46 and 52 before Be ⁇ steaming with metal vapor in a switching process.
- the further metallic housing part 51 distributes a 50 adjacent clamping ⁇ voltage is electrically located at the vacuum interrupter 41 with an open contact system of the first contact 44 and second contact capacitively of the various metallic housing parts, which di-, especially at higher rated voltages.
- FIGS. 5 and 6 show various embodiments of disc-shaped insulators 26 'and 26' 'with undercuts 30' and 30 ", respectively, which illustrate the function of shielding against metal vapor, which is already explained in more detail with reference to FIG effect on the inner surface of the disc-shaped insulator.
- a current ⁇ path of the switch pole 70 is formed, which by Einlei ⁇ th a drive movement of a drive not shown figuratively, shown schematically by the double arrow of Figure 7, can be switched on or interrupted.
- the disc-shaped insulators 6, 26, 26 ', 26'', 46 and 52 all point in the manner described with reference to Figure 1, self- ⁇ shaft that its radial thickness d is so large at least 1.5 times, compared to its axial length L, so that the insulating ability of the vacuum interrupter and their di ⁇ electrical strength over the radial extent of the schei ⁇ benförmigen insulators as Isolierstoffgeophuse Symposiume are reali ⁇ Siert, which leads in all embodiments from imple mentation to a compact and therefore cost-effective design.
