Abstract:
The invention relates to a Method of manufacturing a current terminal for embedded pole part, in which a vacuum interrupter will be moulded by a isolating coverage in a hot and pressure injection process, and pole part itself, in accordance with the preamble of patent claim 1 and 7. It is an object of the invention, that at the position of the upper electric terminal at the fixed contact side of the vacuum interrupter a pressure protecting element (1) is placed into the mould, at least close to the upper part the fixed contact side of the vacuum interrupter (10) and/or together with it, and that the protecting and reinforcement element and the terminal as well as the vacuum interrupter will be embedded by injection moulding.
Abstract:
The present invention is concerned with the embedding of vacuum interrupters, in particular with a vacuum interrupter (300) embedded in an insulating material (301), the insulating material (301) comprising a first main layer (100) having a first sub-layer (101), a second sub-layer (102), and a third sub-layer (103). The second sub-layer (102) is arranged between the first sub-layer (101) and the third sub-layer (103). The first sub-layer (101), the second sub-layer (102), and the third sub-layer (103) comprise fibres, wherein the first sub-layer (101) comprises a group of first fibres (110) which are arranged in parallel with respect to each other.
Abstract:
A low- voltage, medium- voltage or high-voltage switchgear assembly with at least one moveable contact piece, in which the moveable contact is connected to a connection piece electrically with a flexible connecting means. In order in this case to produce a connection between the connector strip and the connection piece of the pole part, which connection has an electrical and thermal resistance which is as low as possible, the invention proposes that the flexible connecting means is connected to the connection piece directly or with an intermediate piece, which can be connected to the connection piece, cohesively or at least unreleasably.
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:
Die Erfindung betrifft einen Mittel- oder Hochspannungs- Vakuumschaltkammer mit mindestens einem aus einer weitestgehend feststehenden Elektrode und einer dazu beweglichen Elektrode bestehenden Kontaktanordnungsystem, gemäss Oberbegriff des Patentanspruches 1. Um hierbei eine möglichst kostengünstige Lösung anzustreben und zu erreichen, dass der Strombahnwiderstand der Vakuumschaltkammer auf niedrigem Niveau gehalten wird, ist erfindungsgemäss vorgeschlagen, dass bei der genannten Vakuumschaltkammer lediglich immer nur ein Kontaktsystem ausgebildet ist derart, dass einem Kontaktstück bzw. eine Elektrode entweder nur ein Radialmagnetfeldkontaktsystem RMF oder nur ein Axialmagnetfeldkontaktsystem AMF gegenübersteht.
