摘要
根据由多台三相异步电动机组成的BMC-400型反井钻机动力系统的具体需求,并以此分析结果,阐述了以西门子S7-200和Sirius 3RW40软启动器为核心的多台电机软启动控制系统的设计和实现方法。
The power system of BMC-400 raise boring machine is composed of seven three-phase induction motors. This article analyses the specific needs of the power control system in detail, and describes the design and implementation of the multi- motor soft-start control system which is composed of Siemens S7-200 and Sirius 3RW40 according to the result.
