矿用高压变频器井下排水泵应用

Application of Underground Drainage Pump with High-voltage Frequency Converter in Mine

本文介绍了新风光矿用一般型高压变频器在山东新巨龙能源有限责任公司新巨龙煤矿中央泵房排水泵应用情况,对应用案例进行了介绍。结果表明,采用单元级联主回路拓扑结构的矿用一般型高压变频器装置,通过无冲击软件启动和无扰切换功能,柴油发电机应急供电状态下使用新风光高压变频器启动一级负荷排水泵可以正常启动,可以解决应急柴油发电机无法启动井下中央泵房排水泵问题,从而保证煤矿应急状态下安全隐患和人身安全问题,具有较高的经济效益和社会效益。

This paper introduces the application of Xinfeng mining general high-voltage inverter in the central pump room of xinjulong coal mine of Shandong xinjulong Energy Co.,Ltd.,and introduces the application cases.The results show that the mining general high-voltage converter device with unit cascade main circuit topology can start normally by using Xinfeng high-voltage converter to start the primary load drainage pump under the emergency power supply state of the diesel generator through the non impact software startup and undisturbed switching function,which can solve the problem that the emergency diesel generator cannot start the drainage pump of the underground central pump room,So as to ensure the safety hidden dangers and personal safety problems in the coal mine emergency state,which has high economic and social benefit s.
