Temperature rise test method of hot bridgewire EED under steady conditions

In this paper, the temperature rise method of the hot bridgewire electro-explosive device (EED) under the steady conditions is proposed. The optical fiber temperature test technique is employed. Since the measurement range of the temperature is limited for this technique, the extrapolation method is used. The relationship between the injected current (or the field strength) and the temperature rise of the bare bridgewire is analyzed and validated by experiment. The work in this paper is the basis for proposing the high-level field radiated susceptibility test methods of the systems containing hot bridgewire EED in the future.
