通过瞬态脉冲试验得到电火工品的电阻和集总热散失系数,结合升降法得到的安全电流对集总热散失系数进行补偿,并采用Rosenthal模型预测电火工品的安全电流。结果表明该预测方法准确度较高,可以用来预测单发电火工品的安全电流。 The resistance and the total heat loss coefficient of the electro-pyrolysis products are obtained by transient pulse test, and the lumped heat loss coefficient is compensated by the safe current obtained by the lifting and lowering method. The Rosenthal model is used to predict the safety current of the electro-explosive products. The results show that the prediction method has high accuracy and can be used to predict the safety current of single power generation explosive.
