摘要

363 kV线路作为西北地区的主干线路，发展形式良好，市场前景广阔。但随着科技的进步，某公司的363 kV产品已无法适应日趋激烈的竞争环境。文中以断路器、隔离/接地/快速接地开关、母线为基础，介绍公司新研制的363 kV GIS整体参数、产品设计和型式试验情况。断路器设计时分析了大电流容量试验电弧能量对弧触头的烧蚀情况，断口间五柱支撑结构；隔离/接地/快速接地开关设计时分析了绝缘、温升等；母线设计时分析了导体温升和绝缘盆子电场、机械强度。型式试验表明：新研制的363 kV GIS满足高参数要求，断路器额定短路电流63 kA，标准时间常数120 ms，快速接地开关达到超“B”类；目前已取得第三方全套型式试验报告，正式应用在中国西北地区变电站工程项目。

Abstract

363 kV transmission line

as the main line in the Northwest Region of China

has a good development situation and broad market prospects. However

with the progress of science and technology

363 kV GIS from a certain company has no way to adapt to the increasingly fierce competitive environment any longer. In this paper

the circuit breaker

disconnector/earthing switch/fast earthing switch are taken as the base

the overall parameters

design and type test of the 363 kV GIS which is newly developed by our company is introduced. In the design of circuit breaker

the ablation of arc energy on arcing contact during the high current capacity test and the five-column support structure across open contacts are introduced. In the design of disconnector/earthing switch/fast earthing switch

the insulation and temperature rise ect are analyzed. And in the design of busbar

the temperature rise of conductor

the electric field and mechanical strength of the insulating spacer are analyzed. The type test shows that the newly developed 363 kV GIS meets the high parameter requirements. The rated short-circuit current of the circuit breaker is 63 kA

the standard time constant is 120 ms and the fast earthing switch meets the super class ‘B’. At present

the product has obtained full set of type tests report released by the third independent test authority and is officially applied to the substation project in the northwest region of China.
