摘　　要：简要介绍了扭矩限制器的结构和工作原理。从风力发电机组现场故障数据分析入手,排查分析了扭矩限制器损坏的原因。通过排查,发现扭矩限制器结构设计存在缺陷,摩擦片受到的预紧力不能及时补偿,导致打滑的发生,根据理论分析结果,提出改进方案,然后对改进方案进行理论计算,最后通过对比试验,证明改进方案的有效性、理论分析与推导的正确性。This paper introduces the structure and working principle of torque limiter.Starting from the analysis of the field fault data of wind turbine,the causes of the damage of the torque limiter are investigated and analyzed.Through the investigation,it is found that there are defects in the structural design of torque limiter,and the preload on the friction plate cannot be compensated in time,resulting in slipping.According to the analysis results,the improvement scheme is proposed.Finally,the effectiveness and theory of the improvement scheme are proved through the comparative test.
