高压套管技术标准发展现状

Technical Standard Progress of High Voltage Bushings

在分析高压套管国内外基本状况的基础上,重点剖析了高压套管技术标准发展现状,包括高压试验、运行检修和抗震等,展望了高压套管的技术发展方向。主要包括:1)我国高压套管的工业体系建立相对较晚,在材料开发、结构设计、工艺优化和试验技术等方面取得了突破性进展,但跟欧美发达国家仍然有一定差距;2)与欧美国家相比,我国在特高压套管标准体系方面相对领先,并且高压套管的运行检修标准相对完善;3)我国高压套管抗震标准以IEC和IEEE标准为基础,结合了我国生产和运行的实际情况。

The author introduced the current status of high voltage bushing at home and abroad firstly,and then focused on analyzing the development status of high voltage bushing standards,including the testing,maintenance and seismic resistance of high voltage bushing.Finally,the technical development of direction was summarized.It summarizes the progress include:1)High voltage bushing industrial system of China was established relatively late,and breakthroughs have been made in material development,structural design,process optimization,and test technology.However,compared with developed countries such as Europe and the United States there is still a certain gap overall.2)Terms of UHV bushing standards in China maintain relatively leading status of the world,especially in operation and maintenance.3)The seismic standards for high voltage bushing were based on IEC and IEEE standards,combined with the actual conditions of production and operation in China.
