高海拔中压开关柜的设计探讨

Discussion on Design of High Altitude Medium Voltage Switchgear

据统计,我国65%的地区海拔高度在1000 m以上,33%的地区海拔高度超过了2000 m,随着经济不断发展,特别是西部地区经济的发展,高海拔中压开关柜的需求量越来越大。但按照国内及国外对于成套电气设备的最高海拔规定,成套电气设备的最高海拔不得超过1000 m。与其他低海拔地区的中压开关柜相比,高海拔中压开关柜的设计、生产及安装要求都不相同。对此,基于高海拔中压开关柜的相关标准及资料,对高海拔中压开关柜的设计进行全面的阐述和探讨,为往后的工程设计提供帮助。

According to statistics,65%of regions in China have altitudes of over 1000 m,while 33%have altitudes of over 2000 m.With the continuous development of national economy,especially in the western region,there is an increasing demand for high altitude and medium voltage switchgear.However,the highest designed(and acceptable working)altitude for assembled electrical equipment manufactured both at home and abroadare limited lower than 1000 m.Compared with medium voltage switchgear for low altitude areas,the design,production,and installation requirements of high altitude applicationsare all different.This article comprehensively elaborates and explores the design of high altitude medium voltage switchgear based on relevant standards and materials,hoping to provide some help for future engineering design.
