The invention relates to a switch cabinet and its cabinet body. The switch cabinet comprises a cabinet body, an eyebrow and an eyebrow cover plate arranged at the top of the cabinet body. The eyebrow cover plate comprises an eyebrow cover and two sealing side plates. The eyebrow, an eyebrow cover plate and the top plate of the cabinet body are surrounded by a tubular chamber with openings at both ends. A small bus is arranged in the tubular chamber, and the sealing side plate is movably assembled at the opening of the tubular chamber The blocking side plate opens or closes the opening of the cylindrical chamber by moving. The eyebrow covers of the left-end cabinet, the right-end cabinet and the middle cabinet are interchangeable, which avoids the design of eyebrow covers selection in the design stage and improves the assembly progress of switchgear. In addition, during the expansion and expansion of substation, the opening of the cylinder chamber can be opened by blocking the side plate, and the end cabinet can be changed into the middle cabinet without replacing the eyebrow covers. Cost of substation expansion.

开关柜及其柜体
本专利技术涉及开关柜及其柜体。
技术介绍
在传统的成套开关设备中,开关柜的眉头除了贴明开关柜编号及用途外,还需放置二次铜棒和接线端子等为开关柜的仪表提供电源和控制信号等,上述二次铜棒即小母线,接线端子即小母线端子。授权公告号为CN206461245U,授权公告日为2017.09.01的中国专利公开了一种中置柜柜顶小母线室,包括眉头、眉头盖板和小母线端子,所述眉头盖板为分体式结构,所述分体式眉头盖板由眉头盖和后支撑板两部分组成,眉头盖的后侧通过旋转铰链连接,眉头盖的另一侧通过六角螺栓固定在眉头上,后支撑板的另一侧通过六角螺栓固定在柜体上。由柜体、眉头和眉头盖板组成一个小母线室,且小母线室的结构方便眉头盖的开启操作。为了对小母线等进行防尘和防鼠防护,现有技术中,还会在上述小母线室的两端开口处分别设置一个封堵侧板,使小母线室形成一个封闭隔室。因此成套开关设备中,眉头盖板分为左端柜、右端柜和中间柜眉头盖板三种类型,所述左端柜眉头盖板即为具有左封堵侧板的眉头盖板,所述右端柜眉头盖板为具有右封堵侧板的眉头盖板,而中间柜眉头盖板则不需要设置左封堵侧板和右封堵侧板,这样左端柜、右端柜和中间柜并柜完成后,各开关柜柜体的顶板、眉头与眉头盖板共同围成一个封闭隔室。不难看出上述左端柜眉头盖板、右端柜眉头盖板和中间柜眉头盖板的结构均不相同,不具有互换性,一方面在设计阶段容易造成眉头盖板选型错误,影响装配进度、拖延工期;另一方面,若前期的端柜旁需要新增开关柜,前期的端柜则变成中间柜,由于眉头盖板不具有互换性,端柜的眉头盖板在中间柜上将无法适用,需要更换合适的眉头盖板, ...
