Abstract
A make contact system for high-voltage applications includes a vacuum switching tube having two switch contacts in the form of plate contacts, of which at least one is a moving contact coupled to a drive. At least one plate contact is rotationally symmetrically surrounded by a shielding element, and the shielding element has an electric conductivity which is less than 40×10−6 S/m.
Claims8
A make contact system for high-voltage applications, the make contact system comprising:
- a drive;
- a vacuum switching tube having two switch contacts formed as plate contacts, at least one of said plate contacts being a moving contact coupled to said drive;
- and
- a shielding element rotationally symmetrically surrounding at least one of said plate contacts, said shielding element having an electrical conductivity of less than 40×10−6 S/m on an iron basis;
- said plate contacts being spaced apart by a distance of less than 10 mm per 100 kV rated voltage in an opened state of said plate contacts.
