The invention belongs to the technical field of urban rail transit power supply contact networks, and particularly relates to a sectional insulator. The device solves the problems of inconvenience inreplacement and high replacement cost when the type of a busbar is adjusted and replaced by a contact network line. The sectional insulator comprises an insulating rod and a mounting base fixedly connected to the insulating rod; a mounting cavity is formed in the mounting base, a first fastening hole and a second fastening hole which are communicated with the mounting cavity are formed in the sidewall of the mounting base, a converter is arranged in the mounting cavity, and when the converter is connected with the rigid busbar, a first fastener for connecting the converter with the mounting base is arranged in the first fastening hole; and when the converter is connected with the flexible busbar, a fastener II for hinging the converter with the mounting base is arranged in the fastening hole II. When the overhead line system line is adjusted and the busbar type is replaced, replacement is convenient, and the replacement cost is reduced.
本发明属于城市轨道交通供电接触网技术领域,具体涉及一种分段绝缘器。它解决了当接触网线路调整,更换汇流排类型时,更换不方便,更换成本高问题。本分段绝缘器,包括绝缘棒和固连于绝缘棒上的安装座,其特征在于,安装座上开设有安装腔,安装座的侧壁上开设有与安装腔相连通的紧固孔一和紧固孔二,安装腔内设有转换器,当转换器连接刚性汇流排时,紧固孔一内设有连接转换器与安装座的紧固件一;当转换器连接柔性汇流排时,紧固孔二内设有使转换器与安装座铰接的紧固件二。本发明实现了当接触网线路调整,更换汇流排类型时,更换方便,降低更换成本。
