矿用一般型大功率不间断电源的研制

Development of General High Power Uninterruptible Power Supply for Mining

研发了一种矿用一般型大功率不间断电源,它能够在井下变电所故障并断电情况下,立即为井下变电所提供照明、开关柜保护及自动化控制系统的供电电源,实现无缝切换,为控制系统可提供6小时以上的后备电源。该设备解决了现有煤矿井下主配电室采用的高频小功率不间断电源功率小、运行带电时间短及在井下环境壳体容易腐蚀的难题。其应用能解决煤矿主配电室PT柜不间断电源更换时间短,带载能力差的问题,其应用能够降低安全隐患,提高工作效率。

A kind of general high-power uninterruptible power supply for mining was developed. It can provide lighting, switch cabinet protection and power supply for automatic control system for underground substation immediately in case of failure and power failure, realizing seamless switching and providing backup power supply for control system for more than 6 hours. The equipment solves the problems of low power uninterruptible power supply of high frequency and low power used in main power distribution room of underground coalmine, such as low power, short running time and easy corrosion of shell in underground environment. Its application can solve the problems of short replacement time and poor carrying capacity of PT cabinet uninterruptable power supply in main power distribution room of coalmine,and can reduce the hidden danger of safety and improve work efficiency.
