交流调速技术目前在工业领域的应用范围正逐步扩大 ,交直交变频调速是其中比较主要的一种。MG TY4 0 0 90 0— 3.3D型采煤机利用此技术实现了电牵引 ,取得了比较好的经济效益。该采煤机采用机载式交直交变频调速技术 ,变频器是ABB公司的产品 ,并配合专用的变频调速电动机 ,设计运行频率为 3Hz,5 0Hz,84Hz ,起动扭矩为额定扭矩的 1.8倍
AC speed control technology is currently in the field of industrial applications are gradually expanding, AC and DC AC speed control is one of the more important. MG TY4 0 0 90 0- 3.3D coal shearer using this technology to achieve the electric traction, and achieved good economic benefits. The shearer adopts on-board AC-AC variable frequency speed regulation technology. The inverter is a product of ABB Company and cooperates with a special frequency-variable speed regulating motor. The designed operating frequency is 3Hz, 50Hz, 84Hz and the starting torque is 1.8 Times
