In the development of ultra high-voltage (UHV) vacuum circuit breakers (VCB), higher current-rating and improved thermal performance become more and more important to provide safe function and reliability in spite of scale-down and increasing performance demanded of modern devices. Due to the high complexity of heat generation and loss processes, it is not easy to predict temperature-rise of the breaker...
The capabilities and advantages of vacuum interrupters have been widely recognized on switching and controlling the fault currents in medium voltage level, and there have been doing various research and developments for using vacuum interrupters in transmission and distribution lines due to its environmental friendliness. Axial magnetic field electrodes are widely used in vacuum interrupters because...
The capabilities and advantages of vacuum interrupters (VIs) have been widely recognized on switching and controlling the fault currents in medium voltage level, and there have been doing various research and developments for using VIs in transmission and distribution lines due to its environmental friendliness nowadays. An axial magnetic field (AMF) electrode has more advantages of the switching...
