FORCIBLY TRIGGERED SPARK GAP WITH SERIALLY CONNECTED DOUBLE-GAP

摘要

Provided is a forcibly triggered spark gap with serially connected double-gap, comprising self-discharging main gaps G1 and G2 connected in series, and a gap triggering system; the two terminals of the forcibly triggered spark gap are respectively connected to a high-voltage terminal and a low-voltage terminal; and the gap triggering system is connected in parallel with the self-discharging main gap connected to the low-voltage terminal. The forcibly triggered spark gap is suitable for use in a series compensation device or a series resonance-type of fault-current limiter or a quick bypass capacitor unit. The forcibly triggered spark gap reduces the voltage value for reliable triggered discharging, thus improving protection and coordination performance as well as triggered discharging stability and reliability.
