Abstract: The invention relates to a pole part of a low- voltage, medium-voltage or high-voltage switching device having a vacuum interrupter chamber, which has been cast inco insulating material and has been provided with a fixed contact and a movable contact, the cast insulating casing being open at the bottom in the region of the movable contact or the drive rod driving said movable contact, in accordance with the preamble of patent claim 1. In order in the process to reduce the heating of pole parts so that a higher rated current carrying capacity is therefore produced, the invention proposes that, in the region of the movable contact or the articulation point of the drive rod (3), at least one ventilation opening (7) is applied which passes through the wall of the insulation (2), the boundary zone between the insulation and an electrical connection piece or through an electrical connection piece (4) of the movable contact.

Abstract: The invention relates to a method for production of a pole part of a medium-voltage switching device, and to a pole part itself, as claimed in the preamble of patent claims 1 and 6. In order in this case to ensure that the costly pressure reinforcements are avoided at least on the switching contact side of the vacuum interrupt chamber in the area of the mold core, while nevertheless achieving an optimum injection-molded result, the invention proposes that before the encapsulation process, a compensation ring is positioned as a separate injection-molded seal on or close to the external circumferential line of the vacuum interrupt chamber cover, between the lower cover of the vacuum interrupt chamber and the mold core and then also encapsulated such that it remains as a lost seal in the encapsulation, with the mold core then being removed again.

Abstract: The invention relates to a breaker with a gas drive for low-voltage, medium-voltage and high-voltage switching devices, in which disconnection can be generated via detonation capsules. In order in this case to ensure that the case of only a low number of connection and disconnection operations in relation to the total operating duration of the circuit breaker is also taken into consideration in design terms, without in the process reducing safety, the invention proposes providing a piston/cylinder arrangement (8) with a plurality of detonation capsules (6, 10) for the purpose of generating a limited number of connection and disconnection operations in the cylinder in each of the two cylinder subareas which are separated by the piston.

Abstract: The invention relates to a method for producing an arc-erosion resistant coating, in particular for the interior regions of arcing chambers that are exposed to electric arcs, and to a shield for vacuum arcing chambers that is produced according to said method, in accordance with the general terms of claims 1 and 10. The aim of the invention is to provide a simple method for producing arc-erosion resistant shields, which nevertheless results in practice in an extremely high arc-erosion resistance. To achieve this, a substrate material is provided with an arc-erosion resistant coating in a cold gas injection process.

Abstract: The invention relates to a method to determine the pressure inside of a vacuum interrupter for medium or high voltage use, wherein at least one fixed contact piece and at least one movable contact piece are arranged inside the technical vacuum of a vacuum interrupter, and wherein the contact pieces are electrically connected to external electrical fixation points, according to the preamble of claim 1 and 5. In order to to implement a high accuracy pressure sensoring in the rough conditions inside a vacuum interrupter, without additional means internally to the vacuum interrupter, the external electrical fixation points are connected with an external electrical energy source, and that in the disconnected or open position of the vacuum interrupter, the effect of a cold cathode vacuum gauge will be used, in that the leakage current between the open contacts generates an x-ray induced ionization of the rest- gas inside the vaccum interrupter, and that the resulting current is measured with high resolution, in order to determine by this current the restgas pressure inside the vacuum interrupter.

Abstract: The invention relates to a low-voltage, medium-voltage or high-voltage switchgear assembly as claimed in the preamble of patent claim 1, 9 and 10. In order to ensure in this case that heat that is created is dissipated better to the exterior for convection, the invention in this case proposes that a thermally conductive heat transmission element in the form of a cylindrical casing is provided between the vacuum interrupter chamber, a contact holder and the encapsulation casing, the inner surface of which heat transmission element rests on the vacuum interrupter chamber and the contact holder, and the outer surface of which heat transmission element rests on the encapsulation casing inner surface. Furthermore, a heat transmitter is proposed which can be produced from a thermally conductive plastic using the injection-molding or molding-compound production process. This can then be connected to the pole part through openings. A further option is to fit these heat transmitters before the encapsulation of an assembly with dn encapsulation compound, and then to also cast them in.
