矿井机电技术管理的创新和应用

矿井管理工作的主要内容即为矿井机电技术的管理,伴随着现如今我国科技的不断发展,已经有越来越多的机电设备不断被应用到矿井生产工作中提高矿井机电设备的水平。而近年来伴随我国矿井精细化管理工作的发展对其工作的要求也是越来越严格,这就使得矿井机电技术的管理工作变得更加重,要矿井企业机械化水平的高低,直接反映到矿井管理工作的发展,影响着矿井企业的竞争力。对于企业的经济效益,社会效益和产品质量都会产生较为直观的影响,所以为了有效提高矿井内矿井机电技术管理的整体水平,必须创新矿井机电技术管理工作,提高矿井机电企业的经济利益,推动行业的进一步发展,促使矿井机电技术得到更加广泛的全方面推广和应用。

Research on the variable speed system of large power alternating current motor

The development status of the variable speed system of large power AC(alternating current)motor drive in China is introduced.The large power AC drive fed by AC-AC converters(cycloconverters)has developed greatly,and some innovations on the theory and engineering technique have been realized.They have been applied to rolling mills,mine hoists,and so on,and remarkable economic and social benefit has been achieved.The development of AC drive fed by large power IGCT(integrated gate commutated thyristors)AC-DC-AC converter is also introduced.It has excellent performance and reliable operation,and has been used in traction.
