抽水蓄能电站发电电动机新型定子弹性元件安装

Installation of new stator elastic element for generator motor in pumped storage power station

本文以国内某350 MW抽水蓄能机组新型定子弹性元件安装与质量控制为例,在解析新型弹性元件基本原理的基础上,详细阐述了新型定子弹性元件安装过程中调整、固定、焊接及质量控制的重点和难点。结合弹性元件安装完成后定子铁心磁化试验和机组运行实测数据,进一步验证了弹性元件安装过程的可行性和有效性,为同类型机组弹性元件安装提供借鉴。

This paper elaborates the key points and difficulties about adjustment,fixing,welding and quality control of the new stator elastic element during its installation by taking the installation and quality control of a new type of stator elastic element for a 350MW pumped storage unit in China as an example and analyzing the basic principles of the element.In combination with the magnetization test of stator core and the measured data of unit operation after the installation,the feasibility and effectiveness of the installation process of the element are further verified.This provides a reference for the installation of elastic elements in similar units.
