Mine Hoist Energy Feedback and Energy Saving Technology Research

矿井提升机的节能降耗已经引起业界的高度重视.在矿井提升机节能的实践应用中,能量回馈节能技术能将矿井提升机运动过程中产生的机械能通过能量回馈器转换成电能,传统的矿井提升机均采用大功率电阻以热能形式自由耗散,而能量回馈型节能矿井提升机将部分再生制动能量回收经过处理后反馈到电网,然后把这些电能输送回交流电网供给其他用电设备来使用,使其比同等拖动方式下的传统矿井提升机节能最高可达15％～30％,这样一来矿井提升机使用过程中的节电效果是相当明显的.

at present, the energy saving of mine hoist has been attached great importance to the industry. Energy saving in mine hoist in the practical application of energy saving technology, ehergy feedback can be generated in the process of mine hoist motion mechhnical energy through the energy feedback device is converted into adopts the high-power resistance in the form of heat electric energy, the traditional mine hoist dissipation and freedom, energy feedback type energy-saving mine hoist will be part of the regenerative braking energy recovery after treatment is fed back to the grid, then the electric energy is transported to AC power supply other electric equipment to use, making it more than the same driving style of mine hoist under the traditional energy is up to 15%-30%, so the mine hoist used in the process of energy- saving effect is quite obvious. In this paper, energy feedback type energy-saving mine hoist ,in the practice of technology are discussed
