Development of Vacuum Interrupters with High Interrupting Capacity
IEEE Transactions on Power Delivery, 1987Vacuum interrupters, in which axial magnetic field type electrodes and CuCr contact materials are ccnbined, show excellent performance from all points of view. By this combination of electrode and contact material, the arcing phenomenon is scmewhat different from that of existing combinations. We have investigated the arcing and dielectric phenanena in

Reignition current interruption characteristics of the vacuum interrupter
IEEE Transactions on Power Delivery, 1988The high-frequency (70-600 kHz) current-interrupting capability of the vacuum interrupter has been investigated using an LC surge testing circuit. Three parameters were examined: di/dt, (di/dt)/gap, and Q*(di/dt)/gap, where Q is a quantity that represents the amount of residue between contacts at zero reignition current. It was found that Q*(di/dt)/gap

Interrupting abilities of vacuum interrupters with horseshoe electrode
SPIE Proceedings, 1994In this paper, the high current vacuum arc behavior with horse shoe electrode has been described. These are dynamic vacuum arc distribution, the maximum current density related to the interrupting limit and factors which influences the interrupting limits. Then based on the above analyses, several vacuum interrupters within (phi) 70 mm outside diameter

Interrupting capability of vacuum interrupter by various parameter
2012 IEEE International Power Modulator and High Voltage Conference (IPMHVC), 2012Vacuum interrupter (VI) has been commercially available in medium voltage switching equipment. Recently, the development of the VIs is focused to reduce the size. Thus, it is necessary to a smaller size contact. In this paper, we investigated the interruption behavior in the real VI with two different contact size of the transverse magnetic field (TMF)

2014 International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV), 2014
Vacuum circuit breakers are extending their applications from low/medium voltage level to high voltage level due to their good properties. Multi-break vacuum circuit breakers are used in special applications because thry have better breaking capability and withstand higher breakdown voltage compared with single-break vacuum circuit breakers.

The self actuating vacuum interrupter (SAVI): A new concept in vacuum interrupter technology
2016 27th International Symposium on Discharges and Electrical Insulation in Vacuum (ISDEIV), 2016This paper describes a new approach to the design of Vacuum Interrupters. Presently a Vacuum Interrupter (VI) is a component of electrical switchgear, which relies on an external mechanism to provide the movement of the contacts required for switching operation.
