本文通过对国内外压电引信几种线路的分析探讨,说明了加泄漏电阻的目的各不相同。对于高内阻电雷管,以箭引-8为例,证明了压电陶瓷二端并联泄漏电阻的主要目的是为了泄漏掉压电陶瓷二端产生的热释电荷,完全不同于美国压电引信在压电陶瓷二端并联泄漏电阻的作用。泄漏电阻的作用不在于其在线路中的位置,而取决于雷管等各种参数。 This paper analyzes and discusses several lines of piezoelectric fuze both at home and abroad, which shows that the purpose of adding leakage resistance varies. For the high internal resistance electric detonator, the arrow cited -8 as an example, proved that the main purpose of the two ends of the piezoelectric ceramic leakage resistance in parallel is to leak out of the piezoelectric ceramic both ends of the pyroelectric charge, completely different from the United States piezoelectric fuze Piezoelectric ceramic in parallel at both ends of the role of leakage resistance. Leakage resistance does not lie in its position in the circuit, but depends on the detonator and other parameters.
