Abstract :
Methods for on-line monitoring of the pressure in vacuum interrupters were investigated. Some experiments were carried out to investigate the characteristics of an inverted magnetron vacuum gauge in pulsed operation mode. According to the experimental results, a kind of vacuum chamber with intellectualized vacuum sensor was developed to implement the on-line monitoring of pressure in vacuum interrupters. The vacuum sensor can measure pressures ranging from 3times10-4 Pa to 0.5 Pa
