刮板输送机应用电气软启动时的堵转保护

Motor blockage protection at start with electrical soft start mechanism at scraper conveyor

介绍了电气软启动、双速电机、液力耦合器的启动原理,提出了电气软启动堵转保护的必要性及技术实现途径,并说明了实用效果。

With some introduction into the starting mechanisms of electrical soft starting, dual--speed motors and hydraulic couplings, this paper proposes the necessity of motor blockage protection for electrical soft starting and technical solutions. The actual application result are also presented.
