摘　　要：介绍了等离子点火器的结构以及工作原理。结合DLZ-200型等离子点火器在实际投入使用过程中出现的漏水问题,选用压电加速度传感器拾取漏水产生的振动信号,利用LabVIEW搭建监控界面并进行数据存储,通过HHT时频分析得到漏水信号的边际谱,通过大量实验得到等离子点火器漏水的检测标准。The structure and working principle of plasma ignition are introduced. Combined with the leakage problem of DLZ-200 type plasma ignition in practical application, the piezoelectric acceleration sensor was choosed to collect the vibration signal caused by leakage, using LabVIEW to build monitoring interface and data storage. The marginal spectrum of leakage signal is obtained by HHT time-frequency analysis. Through a large number of experiments, obtained the detection standard of the leakage of plasma ignition.
