摘要:
进行了电火工品瞬态脉冲试验,利用电热响应曲线计算了电火工品桥丝的温升,根据温升大小将电火工品分组进行升降法试验和发火试验。升降法试验表明温升较大组的电火工品 50%发火电流较低,t检验结果表明这 2组电火工品的 50%发火电流有显著差异。发火试验结果说明,在相同的试验电流下,温升较大组的电火工品发火个数较温升小的多。2项试验结果表明,温升大的组感度较高,说明瞬态脉冲试验是一种可对电火工品进行感度分类的方法。
Abstract:
The transient pu lse testing is employed to eva luate the sensitiv ity performance o f e lectro-exp losive dev ices ( EEDs) . The temperature rises o f bridgew ire are calculated according to the therma l responce curve o f EEDs. The EEDs are c lassif ied into severa l groups accord ing to the temperature rise. The up and down method is used to estim ate the 50% f iring currents of the EEDs that are sampled from the groups hav ing different ranges o f temperature rise. The experimental result show s that the 50% firing current o f the group w ith higher temperature rises is low er, and t-ana lysis presents there is no tab le d ifference betw een 50% f iring currents of the tw o groups. The firing test also show s the f iring amount o fEEDs hav ing h igher temperature rises ismore than that hav ing low er temperature r isesw hen the current o f firing test is the same. The results show that the h igher the temperature rise is, themore sensit ive the EED is, and it is feasible to use transient pulse testing for sensitiv ity classificat ion of e lectro-explosive dev ices.
