国家电网公司加快智能变电站的建设,即一次预制舱在智能变电站得到应用外,一些变电站已开始使用了二次预制舱。文章介绍了二次舱的结构、舱体围护系统、接口、布线方案、舱内支撑系统、舱接地及抗干扰、运输与吊装等。举例二次预制舱在山西晋中介休石河110k V输变电工程中应用,阐述预制舱的优势,以供参考。
State Grid Corporation to speed up the construction of smart substations, that is, a prefabricated cabin in smart substation applications, some substations have begun to use the second prefabricated cabin. This paper introduces the structure of secondary chamber, enclosure system, interface, wiring scheme, cabin support system, tank grounding and anti-jamming, transportation and lifting. Example The second prefabricated cabin is applied in 110k V power transmission project of Hunshihuai in Shanxi Jinzhong, explaining the advantages of prefabricated tanks for reference.
