火炸药粉尘爆炸最小点火能量的实验研究

Experimental Investigation on Minimum Ignition Energy of Dust Concomitant with Power and Explosive Material

建立了火炸药粉尘爆炸最小点火能量的测试系统,对电极间隙、放电回路中串联电阻、粉尘浓度等对最小点火能量的影响进行了实验研究和分析,得到部分火炸药粉尘云最小点火能量的测试结果,为确定用于火炸药危险场所电气设备的防爆形式和结构参数提供参考依据。

The test system of minimum ignition energy of dust concomitant with power and explosive material was established. The influences of electrode clearance, resistance in series in discharge loop and concentration of dust concomitant on minimum ignition energy were tested and analyzed, and the test result of minimum ignition energy was received. The research offers reference data for determining the type of explosion protection and structural parameters of electrical equipment used in the hazardous area where presents power and explosive materials.
