HIGH-VOLTAGE MULTIBREAK CIRCUIT BREAKER WITH MEANS FOR ACCELERATING RESTORATION OF NORMAL VOLTAGE DISTRIBUTION FOLLOWING SPARKOVER AND CLEARANCE OF ONE BREAK

摘要

High-voltage multiple-voltage electrical circuit interrupter device with means for accelerating the restoration of the normal voltage distribution, characterized by comprising; (a) a plurality of interrupting main interrupts, electrically connected in series, said switch being of the type that, during normal opening operations, depends on said interruptions to resist full open circuit voltage, without the aid of a disconnect switch, connected in series, (b) a plurality of capacitors connected in series, respectively connected through said interruptions to distribute voltage between the interrupts, when the circuit breaker is open, (c) a plurality of highly ohmic resistors, connected in series with each other and respectively connected through said capacitors during and after the opening operation of the switch, (d) each of said resistors having a value such that the time constant of a loop circuit, said resistor and capacitor comprising said resistor, is between 0.2 and 5 cycles in a base of 60 cycles per second, (e) the values of said resistors being high enough so that the total current through the open circuit breaker is no more than substantially 30% greater than the current, which passes through it, with said resistors absent.
