Abstract

The invention relates to the electrical field, and discloses a comb-shaped electric pulse igniter which comprises a direct-current power supply module, a self-oscillation circuit, a high-voltage rectification energy storage circuit and a charge-discharge and ignition circuit. When the circuit is switched on, stable and oscillating voltage is generated by the self-excited oscillator firstly, then the voltage is boosted and energy is stored by the capacitor through the high-voltage rectification energy storage circuit, and finally energy is released in the charge-discharge and ignition loop, a discharge pulse gap is broken down, discharge sparks are generated, and combustible materials are ignited. In order to increase the energy utilization rate and enlarge the application scene, a comb-shaped discharge electrode plate is adopted in an ignition loop, and compared with a traditional parallel electrode plate, the comb-shaped electrode plate has the advantages that the charge density at the tip is larger, and loop discharge energy can be gathered with the higher utilization rate. The device can continuously discharge, is safe and high in stability, is convenient to operate, and can be used for various scenes.

Description

technical field [0001] The invention relates to the electrical field, in particular to a comb-shaped electric pulse igniter. Background technique [0002] Electric pulse ignition technology is the ignition technology adopted by many dangerous combustibles. In dangerous fields such as natural gas cookers, gas water heaters, detonators, etc., sufficient safety guarantees are required for ignition. The traditional piezoelectric ignition method, due to the short discharge time and successful ignition The low efficiency has been gradually replaced by electric pulse ignition technology, which uses the ignition spark generated by high-voltage pulse discharge to ignite combustibles, sustainable discharge, safe and convenient. [0003] At present, the discharge electrode plates used in the electric pulse ignition technology are generally parallel electrode plates, which require high voltage and frequency for ignition, and the efficiency of utilizing discharge energy is not high. In ...
