Abstract (en)
[origin: US4504711A] A vacuum switching tube is disclosed which comprises two cooperating electrodes each of which includes an electrode body connected to a current conductor rod, a support plate and a contact. The electrode body comprises a ring through which a central bridge extends. Two raised sections are disposed on the ring diagonally opposite each other and offset 90 DEG from the central bridge. The raised sections constitute current transfer points. The main contact is connected to the electrode body only at the raised sections. In the space between the main contact and the ring is disposed a support plate made of a non-magnetic and electrically poorly conducting or non-conducting material. The main contact is supported by a plurality of spacers to provide mechanical strength. The electrode described herein operates with a self-generated axial magnetic field and is particularly well suited for vacuum circuit breakers.
