摘要
针对目前风电场风力发电机集电环故障率过高的现象,通过分析故障统计结果,确定故障原因主要为碳粉短路,而减少碳粉的堆积即可降低碳粉短路故障率。提出了在集电环室内加装碳粉清扫装置的措施,实施后故障率从3.17次/月降至0次/月。
Aiming at the too high fault rate of collecting ring of wind power generator in a wind farm,the statistical result of the faults was analyzed,and based on this analysis,it was determined that the main reason of the faults is short-circuit fault by carbon powder,and to reduce the carbon powder accumulation can reduce the fault rate of short-circuit caused by carbon powder. It was proposed to add carbon powder cleaning device in the collecting ring chamber. After the measure was implemented,the fault rate reduced from 3. 17 times per month to zero.
