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.
Description
technical field [0001] The invention relates to the technical field of rail transit, in particular to an electric sectioning device at a crossing switch. Background technique [0002] The crossing turnout realizes the intersection of non-parallel tracks, but has the advantages of short turnout length, many opening routes, and two main driving directions are straight lines, so it can save land, improve shunting capacity and improve train operating conditions. [0003] In order to meet the requirements of use, the electric section device at high altitude needs to increase the air gap and creepage distance of the electric section device. The current method is to increase the size of the section insulator, but this will increase a lot of cost and Increased the risk of bowing. [0004] Therefore, it has become a technical problem to be solved urgently by those skilled in the art to design an electric sectioning device at a crossing point.
