摘要
分析了国内外1 100 kV气体绝缘金属封闭开关设备(GIS)的制造水平,详细介绍了西开电气公司1 100 kV,6 300 A/63 kA GIS的设计、结构特点及型式试验情况。该断路器具有在直流分量衰减时间常数120 ms的条件下开断短路电流63 kA的能力,额定电流达到6 300 A;隔离开关有不带投切电阻和带投切电阻两种结构,母线接头采用球形转换结构,满足不同的连接要求;电流互感器采用外置式整体浇注结构;整体采用低位布置,抗震性能好。该产品在国家电网专家组的见证下,在国家高压电器质量监督检验中心按照IEC 62271-100—2006、IEC 62271-203—2003、IEC 62271-1—2007、IEC 62271-102—2002等标准完成了全部型式试验项目,并通过了国家能源局组织的产品鉴定。鉴定委员会认为该产品具有自主知识产权,达到国际领先水平。
This paper analyzed the manufacturing level of 1 100 kV SF6 gas insulated metal enclosed switchgear（GIS） of both domestics and abroad,and specifically introduced the design,constructions characteristics and type test of 1 100 kV,6 300 A/63 kA GIS manufactured by Xi＇an XD Switchgear Electric Co.,Ltd..The capacity of CB with breaking short-current 63 kA under the conditions of declining time constant 120 ms of DC component,rated current reaches 6 300 A.The DS with two constructions： one with damping resistor and the other without damping resistor,the busbar joint adopts spherical transferring constructions,which can fulfill different connection requirement.The current transformer adopts the external type with integral casting constructions,and the integral product adopts the lower layout with good seismic performance.This UHV switchgear completed all item of type test which is carried in National Quality Supervision and Inspection for high voltage apparatus according to IEC 62271-100—2006、IEC 62271-203—2003、IEC 62271-1—2007、IEC 62271-102—2002 etc under the witness of national grid expert,and it has passed the product identification of National Energy Bureau.The appraisal committee considers that the product has independent intellectual property rights,and reaches the international advanced level.
