3.6kV Vacuum Interrupter Design [PDF]
This paper analyzes and compares the principle and structure of the vacuum interrupter, so as to determine the selection of materials for the vacuum interrupter, and further compares the structural materials of the interrupter, and compares them from three angles: the shell, the contact, and the shield.
