摘要

介绍了几起新建机组运行事故。通过对定子水系统堵塞造成绕组损坏、定子端部异物造成线圈受损、定子环形引线烧损等事故分析发现

事故均由汽轮发电机在制造和安装过程形成的缺陷所致。对此

提出了相应的建议

以防止新建机组类似事故重复发生。

Abstract

Several operating troubles of newly constructed units have been presented.Through analysis of some troubles

such as winding damage resulted from blockage in water system of the stator

coils injuring due to foeign matters deposited on the ends of stator

and burn-out of loop type lead wire for the stator etc.

it is found that the troubles all are resulted from defects appeared in manufacture and installation process of the turbo-generator sets.Regarding to this

corresponding recommendations have been proposed

to prevent frequent occurrence of similar troubles on newly constructed units.
