矿井变电所后备电源配置方案的选择研究

Research on Selection of Backup Power Supply Configuration Scheme in Mine Substation

后备电源是保障矿井变电所各类配电设备及监控设备在遇到矿井供电系统突发断电事故后,仍能正常运行的重要保障。为使矿井变电所后备电源配置方案更加科学、合理,基于高压配电装置对矿井后备电源的主要要求,具体分析了分散式后备电源及集中式隔爆型不间断电源的特点及主要优缺点,并探讨了通信设备对后备电源的要求。通过对矿井变电所各类配电设备及监控通信设备对后备电源的具体要求及各类后备电源的特点的分析,可为矿井变电所后备电源的选择提供新的思路,进而更好的保障矿井安全生产。

Backup power supply is an important guarantee to ensure that all kinds of power distribution equipment and monitoring equipment in mine substation can still operate normally after encountering sudden power failure of mine power supply system. In order to make the backup power supply configuration scheme of the mine substation more scientific and reasonable, based on the main requirements of the high-voltage power distribution equipment for the mine backup power supply, the characteristics and main features of the distributed backup power supply and the centralized explosion-proof uninterruptible power supply were analyzed. The requirements of the communication equipment for the backup power supply was discussed. Through the analysis of the specific requirements of the power distribution equipment, monitoring communication equipment of the mine substation for the backup power supply and the characteristics of various backup power sources, the mine can be converted into electricity. The choice of backup power supply provides new ideas to better ensure mine safety production.
