The invention provides an electric sectioning device at a cross turnout, and relates to the field of rail transit. The electric sectioning device comprises contact nets, turnouts, section insulators and isolation switch. The contact nets comprise a first contact net and a second contact net. The turnouts comprise a first turnout, second turnout, third turnout and fourth turnout. The section insulators comprise a first insulator, a second insulator, a third insulator and a fourth insulator. The section insulators are connected through contact net transition sections; each section insulator comprises a sliding plate and an insulating rod, the sliding plates comprise a pair of long sliding plates and a pair of short sliding plates which are arranged on the two sides of the insulating rod in astaggered mode, air gaps exist between the long sliding plates and the short sliding plates, arc extinction angles are arranged at the ends, and the isolation switch are arranged between the contactnetwork transition sections and the contact nets. A series gap and isolation switch combined system solution is adopted so that the problem that the sliding plate electrical gap and the insulating rodcreepage distance are increased on the single section insulator is avoided.

    本发明提供了一种交叉道岔处的电分段装置,涉及轨道交通领域,包括接触网,道岔,分段绝缘器以及隔离开关,所述接触网包括第一接触网以及第二接触网,道岔包括第一道岔,第二道岔,第三道岔和第四道岔,分段绝缘器包括第一绝缘器,第二绝缘器,第三绝缘器以及第四绝缘器,分段绝缘器之间通过接触网过渡段相连,分段绝缘器均包括滑板以及绝缘棒,滑板包括交错设置在绝缘棒两侧的一对长滑板以及一对短滑板,长滑板以及短滑板之间具有空气间隙且端部设有消弧角,隔离开关设置在接触网过渡段和接触网之间。本发明采用串联间隙加隔离开关的系统解决方案,规避了在单一分段绝缘器上增加滑板电气间隙和绝缘棒爬电距离的问题。
