摘　　要：介绍了一种经济型船用电动机启动器改进方案,可解决普通星三角启动可能产生的二次冲击电流问题。提出的改进方案在普通星三角启动电路基础上,通过增加三个续流/限流电阻,与电机定子三相绕组先后并联、串联最后旁路切除,实现了在整个启动过程中,电动机定子三相绕组始终不断电、定子绕组电流始终连续。重点说明了改进星三角启动的工作原理、技术方案及对比测试情况,并展望了其应用前景。An improvement scheme of economic type motor starter for marine is introduced. It can be used for solving the problem of secondary impact current which may form during regular star-delta starting. The improvement scheme which is presented increases three additional continued flow/current-limiting resistors on the basis of the regular star-delta starting circuit,and has parallel and series of motor stator three-phase winding end bypass removed. It can achieve that motor stator three-phase winding are never power down and the current of stator winding is always continuous,during the whole startup process. The working principle of the improved star-delta starting,the technical scheme and the comparison test are highlighted. Its future application is also be forecasted.
