某风力发电机着火原因分析与处理

Fire Cause Analysis and Processing of A Wind Power Generator

通过对某发电厂火灾事故原因的分析,注意到需要加强风力发电机日常维护,尤其是电控柜下部母排处,可能存在日常工作和维护时遗留下的短接线或其他导体,容易引起690 V母排发生相间短路。因此在日常管理维护中要定期检查风机内各种电气设备接线,发现松动要及时紧固;加强对电缆外观、连接可靠性、电缆桥架胶皮护套是否脱落等全面检查,防止电气短路。

By analyzing the fire cause of a power plant,we clearly recognized that it is need to maintain the wind power generator.The short connection and other conductors left when in maintainence under electronic control cabinet may cause phase fault of 690 v transmitting line.So the connection of electrical equipment should be checked to fasten the looseness of the equipment.To totally check the cable appearance,connection reliability,rubber jacket cable bridge is to prevent electric short circuit.
