摘要: 分析了矿用变频器存在的主要问题：研发投入不足，价值挖掘不充分，对电网的污染严重及使用维护相对困难；从矿用变频器防爆技术、变频驱动技术和应用技术等方面阐述了矿用变频器的发展趋势：隔爆兼本质安全型仍是未来矿用变频器的主流防爆型式，矿用变频器的防爆工作将主要围绕壳体优化设计、壳体内部环境控制、散热技术革新等方面展开；矿用变频器未来研究的重点是中高压大功率变频器及新技术、新器件的应用，以及变频器的清洁利用与节能应用。Abstract: Main problems of mine-used frequency converter were analyzed that input of research and development is insufficient, value exploration is inadequate, pollution to power net is heavy, and use and maintenance is relatively difficult. Development trends of the mine-used frequency converter were expounded in term of explosion-proof technology, variable frequency drive technology and application technology, namely explosion-proof and intrinsically safe is still mainstream of explosion-proof type for the mine-used frequency converter in the future, explosion-proof research of the mine-used frequency converter will focused on optimization design of shell, internal environment control of shell, innovation of heat dissipation technology. Research focuses of the mine-used frequency converter are application of middle and high pressure and high-power inverter, new technologies and devices in the future, clean utilization and energy saving of frequency converter.
