<p>PURPOSE:To hold a value in the vicinity of the peak value of transient recovery voltage, by connecting a voltage source capacitor, a reactor, a gap and a commutation capacitor in series and inserting a rectifier between the gap and the commutation condenser. CONSTITUTION:When a close switch 4 is closed, a current is supplied to a breaker 6 from a current source circuit consisting of an electrode 1, a reactor 2 and a shortcircuit transformer 3. A blocking order is issued to an auxiliary breaker 5 and the breaker 6 to block the breaker 6. A gap 11 is ignited before or after a current zero point blocking the current from the current source circuit. Voltage almost corresponding to the charging voltage of a voltage source capacitor 7 appears in a commutation capacitor 12 within a short time. A voltage peak value is held to the commutation capacitor 12 by a rectifier 15.</p> |
