定子铜线圈在内冷水中的腐蚀与控制
Corrosion and Protection of Stator Copper Coil in Internal Cooling Water
摘 要
定子线圈作为发电机的组成部件，由空芯铜导线绕成，冷却水在其中流通。定子线圈在长期运行中不可避免会发生腐蚀，腐蚀产物的积累使内冷水的水质恶化甚至引起水路堵塞，严重影响电力系统的运行安全。针对发电机定子线圈的腐蚀问题，介绍了定子内冷水水质特性及其对定子铜线圈腐蚀行为的影响，讨论了定子铜线圈在内冷水中的腐蚀现状、影响因素及腐蚀控制方法，总结归纳了铜的新型缓蚀剂，并介绍定子线圈的清洗保养方法。

Abstract
As a component of generator, the stator coil is made of hollow copper wire, in which the cooling water flows. The corrosion of stator coil is inevitable in long-term operation. The accumulation of corrosion products worsens the quality of internal cooling water and even causes water blockage, which seriously affects the safety of power production. Aiming at the corrosion problem of generator stator coil at present, this paper introduces the influence of water quality of stator inner cooling water on stator corrosion and how to control the corrosion of stator coil in inner cooling water, summarizes all kinds of new corrosion inhibitors, and introduces the cleaning and maintenance methods of the stator coil. It is hoped to provide a reference for the control of stator coil corrosion in internal cooling water.
