摘要

摘要: 针对煤矿井下供电电源输入电压等级多、用电设备易受到大型设备启停影响的特点，提出了宽电压自适应防爆本质安全型电源设计方案。该电源采用智能移相调压技术和宽电压开关电源技术，通过单片机实现了85~825 V宽输入电压的自动高低压段识别、自动切换、智能移相调压处理；通过脉宽调制方式将波动的电压转换为稳定的直流电压。实验结果表明, 该方案很好地解决了矿井电源多电压等级、输入电压波动范围大的问题。

Abstract: For characteristics that power supplys in coal mine underground has multi input voltage grades and are susceptible to disturbed when big equipments are starting or stopping, the paper put forward a design scheme of adaptive wide-voltage power supply with explosion-proof and intrinsic safety. The power supply uses intelligent phase shift voltage regulating technology and wide-voltage switching power supply technology, and adopts single-chip microcomputer to realize automatic identification of high and low voltage section, automatic switch, intelligent phase shift voltage regulating of 85-825 V wide input voltage, and uses PWM to convert fluctuant voltage to a stable DC voltage. The experiment results show that the scheme solves problems of multi voltage grades and wide-voltage fluctuation of mine-used power supply.
