摘要

Based on the test method of induced current in electromagnetic field, a kind of non-contact test method of induced current for EED was presented, which is colorimetric method measuring temperature with infrared optic fiber. Based on the equivalence of temperature rise of heated EED bridgewire by radio frequency current and DC current, and using the temperature rise as the medium, the induced current of EED in electromagnetic field can be quantitatively measured, through the calibration to EED in direct current.%通过研究电磁场中感应电流定量测试方法，提出了电火工品换能元感应电流非接触式测试方法--红外比色测温法，并搭建了试验装置。根据射频电流与直流加热电火工品桥丝温升的等效性，通过对电火工品换能元进行直流标定，以温升为中间量，实现了定量测量电火工品电磁场中感应电流的大小。
