摘　　要：防爆型式由本质安全型保护的电源电路(含电池保护板电路)在引起电流开关动作前,能够产生一个瞬态大电流值,通过利用高速存储示波器,对这段时间的电压和电流进行测量,计算分析电源电路产生的瞬态能量值,是否高于标准要求,从而判定瞬态能量试验是否合格。Power circuit(including battery protection board circuit)protection by intrinsic safety“i”can generate a transient high current value before causing the current switch to operate.By using a high-speed storage oscilloscope,the voltage and current during this period are calculated.Measure,calculate and analyze whether the transient energy value generated by the power supply circuit is higher than the standard requirements,thereby determining whether the transient energy test is qualified.

关 键 词：防爆本质安全型 示波器分析应用 瞬态能量试验 防爆标准应用
