摘要: 随着特高压工程的建设和发展,钢管塔已大量投运到实际特高压线路工程中。为保证特高压钢管塔线路带电作业的安全开展,仿真计算并对比分析了特高压钢管塔、角钢塔塔身周围的电场分布情况。以1∶1钢管塔模型试验获得各种典型带电作业工况下的操作冲击放电特性,确定了各工况下带电作业的安全距离。通过钢管塔和角钢的冲击放电试验,对比分析了2种塔型结构的操作冲击放电特性。研究成果可在特高压钢管塔同塔双回线路带电作业中提供技术支撑。

Abstract: Along with construction and development of UHV transmission project, steel tubular towers have been widely used. In order to ensure live working safety on UHV steel tubular tower, electric field distribution around UHV steel tubular tower and angle-steel tower are simulated. The impulse discharging characteristics of various typical live working conditions through 1∶1 steel tubular tower model test are analyzed and safety distance for live working under various conditions are obtained. Difference of impulse discharging characteristics between steel tubular tower and angle-steel tower is analyzed by impulse discharging test. The research result can provide technical support for live working on UHV steel tubular tower transmission lines.

Key words: UHV, steel tubular tower, live working, safety distance test
