浅析大型发电机的若干工程质量问题

Discussions on Several Large Generator Construction Quality Issues

我国近年来投产的600 MW机组出现了一些质量缺陷,例如:发电机转子引线夹板处的不锈钢板断裂,发电机绝缘引水管缺陷,发电机引线烧毁,发电机定子槽楔松动等。因此,必须及时对新投产机组进行针对性检查,提前发现设备隐患,确保机组安全运行。有关部门应严格按照相关标准和规程进行新投产机组的全过程监督,包括监造、验收、安装等各个环节,开展防范各项风险工作,以提高机组的安全水平。

Some quality defects occurred in recently operating 600 MW units in China, including generator rotor lead clamp stainless steel plate broken, generator insulated water pipe defects, generator lead burn-out, loosing stator wedge, etc. Therefore, pertinent inspections are required to new operating units to discover hidden troubles and ensure safe operation. According to applicable standards and regulations, relative departments should supervise the entire process of new units, including manufacturing supervision, acceptance, and installation, etc. and carry out risk prevention works to improve unit safety.
