摘要
换流站处于风沙较大地区时,沙尘会对换流站电气设备、建(构)筑物等造成不利影响,严重时甚至威胁着工程的安全运行,伴随着较大规模的特高压直流工程规划落地西北等风沙较大地区,因此有必要对换流站防风沙措施进行深入研究,以确保工程的顺利建设和运行。通过对风沙地区已建设的换流站设计、运行情况进行调研,分别从电气及土建专业角度论述具体措施,从技术角度分析总结了换流站内电气设备、建(构)筑物等防风沙设计措施,以期对后续风沙环境条件下建设变电工程尤其是特高压换流站防风沙设计提供技术支持和参考。
For the converter station located in a sandy area, the dust will cause harmful impact on electrical equipment, buildings and structures in the station, and even threaten the safe operation of the station. Along with a large number of UHV DC projects planned in the sandstorm-prone areas in northwest China, it is thus imperative to canrry out an in-depth study on the sand-prevention measures for the converter stations to ensure their successful construction and operation. Based on an investigation on the design and operation situation of the existing converter stations in sandy area, a summary and analysis is made on the specific sand-prevention measures for the electrical equipment, buildings and structures of the convertor station, which cab provide a technical support and reference to the design of the sand-prevention measures for the future power transformation projects, especially the UHV DC converter stations in the sandy area.
