Abstract

1352073 Spark gaps FRANCE ARMED FORCES MINISTER OF 19 April 1971 [13 April 1970 26854/71 Heading H1X [Also in Division G1] An arc across a switching gap between opposed electrodes 15, 16 of a circuit breaker under high test voltage is struck by a device comprising an explosive charge 10 arranged to be detonated at a selected instant so as to provide a rapid flow of ionized gas into the said gap. The explosive 10, e.g. penthrite with a variable added amount of barium nitrate is carried in a replaceable ring 11 in a housing 8 having a guide channel 9 for the ionized medium. The housing 8 is screwed into a guide tube 12 having a flared end and extending through an insulating wall 13 and screen 14 of the circuit breaker towards the switching gap. The charge is held in position by a ring 20 and is detonated by a charge of lead nitride fired by an exploding wire connected to a coaxial connector 18 protected by a screen 19. The arc is extinguished by an air blast. A plurality of housings 8 and guide tubes 12 may be mounted on a support 17 and fired sequentially in a series of tests or simultaneously to increase the reliability of a single test.
