摘要
介绍了超级电容器的工作原理和特点,为充分利用其优点,用其代替本安电源中的蓄电池,并对其在本安电源储能部分中的应用进行详细设计,将超级电容器组成的储能部分和DC-DC变换部分连接起来在前级进行计算机仿真试验,由前级故障时电源在超级电容器供电时输出电压、电流波形和电容器组块电压波形可知,把超级电容器应用到煤矿井下本安电源中,很好地解决了原来本安电源中蓄电池使用寿命短、维护困难等缺陷。
The paper introduced the working principle and features of the super capacitor. In order to fully play the advantages, the battery in the intrinsic safe power could be replaced by the super capacitor. A detail design was conducted on the apphcation of the super capacitor in the intrinsic safe electric power storage. A computer simulation test was conducted on the energy storage part of the super capacitor and the DC - DC conversion connection at the front stage. Before the front stage fault occurred, the output voltage and the current wave during the super capacitor supplying the electric power and the voltage wave of the capacitor block showed that the energy storage part of the super capacitor could fully meet the electric supply requirements of the rear stage circuit when the electric circuit failed.
