Recently, China's first independently-developed 108-ton AC replacement DC drive system dump truck slowly exits the workshop of Xiangtan Xingda Electromechanical Co., Ltd., marking that Hunan's mining equipment companies have successfully filled the domestic technology gap in this field, breaking the field. International technology monopoly.
High-power advanced AC drive technology has been monopolized by foreign companies for many years, becoming a “bottleneck” for the domestic production of domestic large-scale AC drive electric wheel dump trucks, and the cost of domestic mining vehicles has remained high. The 108-ton AC drive electric wheel dump truck that successfully went offline was a technology upgrade on the basis of the original 108-ton DC drive electric wheel dump truck. Its AC frequency conversion technology was implemented by Xiangtan Xingda Electromechanical Co., Ltd. and China Shipbuilding. The Research and Development of the Heavy Industry 712 Institute is the first of its kind in the country and has obtained a number of national patent licenses.
