高能多次点火装置的设计

The Design of High Energy and Multi-Time Ignition Device

文章介绍了一种应用于定容燃烧弹中的高能多次点火装置的设计和应用方法,该装置解决了在定容燃烧弹中对代用燃料的燃烧特性进行试验研究中出现的混合气体不易点燃的问题。通过对点火能量的分析,发现提高点火能量需增大点火电流、点火电压或放电时间,文章中设计的高能点火装置提高了点火电流和放电时间,增加了点火次数,从而增大了点火能量,提高了点火可靠性,对于过浓、过稀或者温度比较低时的可燃混合气都能成功点燃。

The design and application of a high energy and multi-time ignition device applied in constant volume bomb is introduced in this paper. This device can solve the problem that the mixture of air and natural gas can not be ignited in the experiments of substitute fuel test, Through the analysis of ignition energy, it＇s found that increasing the ig- nition energy need to increase the ignition voltage or ignition current or discharge time. This device increases the ignition current and ignition energy and it can ignite the mixture of several status successfully.
