Abstract

The invention provides a multi-pole ignition device of an impulse voltage generator. The invention is characterized in that the device mainly comprises a pulse voltage generator, a multi-pole main clearance and a transmission resistance capacitor; the pulse voltage generator consists of a low voltage primary winding W1 and two high voltage secondary windings W2 and W3; the multi-pole main clearance consists of a plurality of small clearances 1; each small clearance 1 is provided with two tungsten-copper alloy rods 13; the transmission resistance capacitor consists of a transmission capacitor 4 and a transmission resistance 5. Owning to short conduction time of the multi-pole main clearance, the ignition process and the ignition pulse transmission process of each pole are achieved at the same time; the impulse voltage generator has good synchronousness, is not required to adjust the sphere gap before the impulse voltage is generated each time and is not affected by the environmental condition, has wide range of triggered voltage and small dispersion, and leads to easy breakdown of the clearance of each pole.

Description

technical field [0001] The invention relates to an ignition device of an impulse voltage generator, in particular to an ignition device capable of stably improving the synchronous performance of the impulse voltage generator. Background technique [0002] At present, the synchronization of the general impulse voltage generator is completed by the ignition ball gap and the middle ball gap. Before charging, adjust the ball gap distance to be slightly larger than the charging voltage. When the voltage is applied to the charging voltage, a pulse is sent to the ignition ball gap. After the ignition ball gap is ignited, the middle ball gaps are broken down one by one due to the natural overvoltage, and finally the isolation ball gap is broken down. However, the ball gap breakdown discharge has a certain time delay, has great dispersion, and is easily affected by external conditions. The breakdown of the next level of the impulse voltage generator can trigger the breakdown of the ...
