Title of Paper:

Study on a new single coil type axial magnetic field contact for high voltage vacuum interrupters

Journal:

IEEE Trans. Plasma Science

Summary:

A new single coil-type axial magnetic field (AMF)contact for high-voltage vacuum interrupters is introduced. Its
AMF characteristics were studied by a finite element method, tak-ing the eddy current effect into account. Vacuum arc appearance of the new single coil-type AMF contact was observed by a high-speed charge-coupled device video camera. Capacitors and reac-tors (LC) discharging current interruption tests up to 45.0 kA were done with a single frequencyLC oscillating circuit. Vacuum arc appearance of the single coil-type and slot-type AMF contacts was compared. The research results show that the new single coil-type AMF contact is more suitable for high-voltage vacuum interrupters than the slot-type AMF one
