A high-voltage vacuum switch
Abstract
The high voltage vacuum switch, which has an arc suppression chamber containing two moving hollow ferromagnetic cores is described. Contacts on the ends, are freely attached to the ends of the leads to the arc suppression chamber by means of the springing elements located in them, and are controlled by an external magnetic field. It is distinquished by the fact that to increase the service life and reliability, bellows are used as the springing elements which are installed in the inner cavity of the cores and which are precompressed. In this case, each of the indicated bellows is connected to the core with one end and to the lead with the other. The switch described is different in that to ensure complete electrical connection of the bellows with the lead, the latter are attached to the end of the lead by means of a sleeve with a stem, located inside the bellows, and a ring encompassing them on the outside.
