摘要:
A current interruption apparatus comprises a series-connected combination of at least one vacuum interrupter and at least one gas-blast interrupter. Each vacuum interrupter is coupled in parallel with a non-linear resistor, while each gas-blast interrupter is coupled in parallel with a capacitor. During the initial period of the recovery voltage developed upon current interruption, most of the recovery voltage is applied to the vacuum interrupter. After the instant at which the non-linear resistor represents its constant voltage characteristics, the SF.sub.6 gas-blast interrupter will take the largest portion of the entire voltage increased thereafter.
