Abstract Electric sparks can ignite fires, initiate explosions, shock humans. These discharges release energies through very complex dynamic processes. The effects of changing energy (capacitance and voltage) and electrode parameters on spark discharge characteristics are investigated. A multi-energy high-voltage ignition system is built. Results show that the spark discharge energy by voltage is more stable than changing the energy by capacitance. The breakdown characteristics of electrodes are revealed under different electrode parameters by the field strength distribution of the electrode. The energy utilization efficiency of large electrode gap is about 5.55% higher than that of small electrode gap.

火花放电的评价

摘要 电火花可以点燃火灾、引发爆炸、电击人类。这些放电通过非常复杂的动态过程释放能量。研究了改变能量（电容和电压）和电极参数对火花放电特性的影响。建立了多能高压点火系统。结果表明，电压变化的火花放电能量比电容变化的能量更稳定。通过电极的场强分布揭示不同电极参数下电极的击穿特性。大电极间隙的能量利用效率比小电极间隙高约5.55%。
