摘要

母线是GIS设备的主要导电回路

设计具有高参数、高性能的母线结构是保证GIS设备可靠运行的基础。母线在发生内部故障电弧时会产生压力升高

从而引起壳体的破坏

会对整体设备运行及人身安全造成严重危害

因此需要对母线在内部故障电弧下的压力升高进行分析。文中介绍了800 kV GIS母线的技术参数和结构特点

对某实际工程母线结构内部故障电弧下的压力升高及烧穿时间进行了详细地分析及计算

通过内部故障电弧型式试验进一步验证了该母线具有良好的耐受内部故障电弧的能力。

Abstract

It is the foundation to develop high-parameter and high-performance busbar for safe operation of 800 kV GIS.Internal fault arc will result in pressure rise of GIS

which damages the enclosure

and harms equipment and human.So it is important to analyze the pressure rise under the internal fault arc condition.This paper introduces the parameters and structure features of a 800 kV GIS busbar

analyzes the pressure rise and burning through time of a real GIS busbar under internal fault arc in detail.Moreover

type tests were conducted to verify that the busbar is excellent in arc suffering ability.
