【Abstract】 The paper introduces the application of switched reluctance drive(SRD)which is directly powered by 1140V. With it, not only the technical performance of electrical haulage shearer is satisfied, but also the 1140V/380 transformer can be spared. The practical application of SRD proves that it has simplified structure and improved reliability, and the design meets the requirement for the application of shearers.更多还原
