摘要
介绍了一种基于DSP的井下隔爆兼本安型直流不间断电源(UPS)供应系统。该系统用DSP实现数字控制,使用锂电池作为后备电源,输入交流660 V/127 V,输出12 V本安以及24 V隔爆直流电源,锂电池能持续2 h的供电,可靠性高,能满足绝大多数设备的供电要求,可以应用于各种需要防爆以及本安的场合。
This paper presents a DSP-based underground explosionproof and intrinsically safe DC UPS supply system. The system achieve digital control with DSP ,use the lithium battery as a backup power supply, use AC 660 V/127 V as input, Output is 24 V explosionproof and 12 V intrinsically safe DC power, lithium battery can last for 2 hours of electricity, high reliability, could meet majority requirements of equipment supply, and be applied to various anti explosive and intrinsically safe occasion.
