Study on 1140 V Four Quadrant SRD Driver for Thin Seam Shearer
Abstract：Aiming at the special requirements of electrical haulage speed regulation device for thin seam shear,the disadvantages of existing speed regulation device is analyzed.The technique scheme of combined 1 140 V SRD（switch magnetic reluctance driver） is proposed.It not only has the advantages of four quadrant operation,directly supply 1 140 V power,but also easy to carry,unload and install,which adapts thin seam shear well.The features and technique difficulties of this scheme are introduced.
