Abstract
The present disclosure provides a method of manufacturing a current terminal for an embedded pole part, in which a vacuum interrupter is molded by an isolating coverage in a hot and pressure injection process, and such a pole part. At the position of the upper electric terminal at the fixed contact side of the vacuum interrupter, a pressure protecting element is placed into the mould, at least close to the upper part the fixed contact side of the vacuum interrupter and/or together with it, and the protecting element, the terminal and the vacuum interrupter are embedded by injection molding.
Claims18
A method for manufacturing an embedded pole part, comprising:
- embedding a vacuum interrupter in a hot process by injecting embedding material in a mould in which the vacuum interrupter is positioned;
- placing, at a position of an upper electric terminal of the pole part at a fixed contact side of the vacuum interrupter, a pressure protecting element into the mould, the pressure protecting element being placed at least one of close to an upper part of the fixed contact side of the vacuum interrupter and touching the upper part of the fixed contact side of the vacuum interrupter chamber;
- and
- embedding the pressure protecting element, the terminal and the vacuum interrupter by injection molding.
An embedded pole part comprising:
- a vacuum interrupter embedded in a hot process by injected embedding material, the vacuum interrupter including an upper electric terminal;
- and
- a pressure protecting reinforcement element arranged at a position of the upper electric terminal of the vacuum interrupter for the embedding of the injection material, the pressure protecting reinforcement element being integrated into an embedding coverage of the pole part.
