The invention provides an electric sectioning device at a single turnout. The invention relates to the technical field of rail transit. The electric sectioning device comprises a turnout, overhead lines, a sectional insulator, and disconnecting switches; the turnouts comprise a first turnout and a second turnout; the overhead lines comprise a first overhead line and a second overhead line. The sectional insulator comprise a first sectional insulator and a second sectional insulator; the section insulator comprises sliding plates and insulating rods, the sliding plates comprise long sliding plates and short sliding plates, air gaps are formed between the long sliding plates and the short sliding plates, arc extinguishing angles are arranged at the ends, overhead line transition sections arearranged between the section insulators, and the disconnecting switches are arranged between the overhead line transition sections and the overhead lines. The two sectional insulators are arranged between the first overhead line and the second overhead line, and the relation of the sectional insulators in an electrical loop is controlled through the disconnecting switches, so that the use condition of the electric sectioning device at a high altitude is met.
本发明提供了一种单开道岔处的电分段装置,涉及轨道交通技术领域,包括道岔,接触网、分段绝缘器以及隔离开关,道岔包括第一道岔以及第二道岔,接触网包括第一接触网以及第二接触网,分段绝缘器包括第一分段绝缘器以及第二分段绝缘器,分段绝缘器包括滑板以及绝缘棒,滑板包括长滑板以及短滑板,长滑板以及短滑板之间具有空气间隙且端部设有消弧角,分段绝缘器之间设有接触网过渡段,隔离开关设置在接触网过渡段与接触网之间。本发明在第一、第二接触网之间设置有两个分段绝缘器并通过隔离开关控制分段绝缘器在电气回路中的关系,满足了其在高海拔处的使用条件。
