The three-ball double-gap double-trigger structure principle was adopted in this design. By means of patent technical measures

total voltage allocated on this two gaps uniformly and the voltage on one gap reduced one half. By this method

distance and diameter decreased

difficulties of design and manufacture simplified and working conditions of ignition device reduced. Therefore

possibility of implementation increased greatly. By the premise of technical performance in accordance with operating requirements

this design obtained higher performance price ratio. Estimated cost price was only one fifth of import equipment.
