The utility model discloses an air-type busbar groove, which comprises a shell. The shell is provided with upper and lower insulators and a group of conductors. The shell is characterized by upper and lower cover plates, each cover plate includes a top plate and two side plates. One end of the side plate is connected with the corresponding side of the top plate, and the other end is provided with a connecting ear plate extending outward and parallel to the top plate. The plate, the side plate and the connecting ear plate are integrated structure, and the upper and lower cover plates are connected at the connecting ear plate. The air-type busbar groove of the utility model is symmetrically arranged with a pair of cover plates to form a shell of the busbar groove. After the conductor assembly is placed in the shell, the connecting ear plates of a pair of cover plates are fixed by riveting to complete the assembly of bus channel. Because the side plate of the shell is omitted, the zero part of the shell is less, the structure is simple, the manufacturing process is simplified and the assembly workload is reduced. At the same time, due to the few connecting parts, the overall sealing performance of busbar groove is good.
【技术实现步骤摘要】
一种空气型母线槽
本技术涉及配电设备
,具体地说是一种空气型母线槽。
技术介绍
对于空气型母线槽系统,导体通过绝缘件支撑在壳体内,导体通过空气介质绝缘。壳体的结构形式和壳体连接的密封性尤为重要。传统的空气型母线槽,如图1和图2所示,壳体由左右两个侧板14和上下两件盖板12组装而成。盖板12和侧板14均呈“U”形结构,侧板14的一对平行侧壁分别通过螺栓紧固件13与上下盖板12连接。上下绝缘件16通过螺栓紧固件15固定在壳体内。这种结构的母线槽壳体,零部件多,工艺繁琐,装配工作量大。同时,由于连接部位较多,装配时盖板和侧板连接处的配合面的密封性差,产品防护等级低。它的另一个缺陷是盖板上还设有安装孔1401,用于连接绝缘件的紧固螺栓,进一步降低了母线槽的密封性能。
技术实现思路
本专利技术要解决的是现有的空气型母线槽壳体结构不合理,装配工作量大,防护等级低,外形不美观的问题,旨在提供一种改进型空气型母线槽,以提高工作效率和产品防护等级。为解决上述问题,本技术采用以下技术方案:一种空气型母线槽,包括壳体,所述的壳体内设有上下绝缘件和一组导体,其特征在于所述的壳体包上下盖 ...
