摘要

换流变压器是高压直流输电中的核心设备之一

其由于绕组和铁心缺陷所引起的机械故障对整个直流输电系统的稳定持续运行造成了严重的危害。文中从换流变压器的的结构特点及在直流输电系统中的工作原理出发

结合宝鸡换流站的站内接线及站内换流变压器的结构特点

采用振动信号分析法对换流变压器振动特性及影响因素进行了理论研究。利用换流变压器振动监测系统对宝鸡换流站中的换流变压器进行了长期现场测试

为振动信号分析法在换流变压器故障检测中的应用提供了一定的基础支撑。

Abstract

Converter transformer is one of the core equipment in HVDC transmission. The mechanical fault causedby the winding and core defects poses a serious hazard to the steady and continuous operation of the entire HVDCtransmission system. In this paper

according to the structural characteristics of the converter transformer and theworking principle in the HVDC transmission system

the vibration characteristics of the converter transformer andthe influence of the converter transformer are analyzed by using the vibration signal analysis method

combining withthe wiring in the station of Baoji Converter Station and the structure of the converter transformer in the station. Theconverter transformer vibration monitoring system is used to carry out a long-term field test of the converter transform-er in the converter station of Baoji

which provides some basic support for the application of the vibration signal anal-ysis method in the fault detection of the converter transformer.
