摘　　要：详细介绍了以电流传感器隔离测量发动机试验点火信号的原理以及实验方法 ,并与 RC测量做一比较。电流传感器隔离测量方法中测量电路完全与点火电路隔离 ,提高了测量的准确性 ,增强了点火试验的可靠性。The principle and the test method of the isolated measurement for firing signal by current sensor are introduced and compared with the RC measuring method. The measuring circuit of the current sensor isolated measuring method is completely isolated from firing circuit, thus the measuring accuracy and test reliability can be improved.
