Technical Field

The invention relates to the technical field of electrified contact networks of railways, in particular to a high-speed rail traction power supply additional line suspension system.

Background

The method improves the railway transportation capacity, comprehensively utilizes power resources, reduces environmental pollution, realizes the purposes of low investment and good effect, and accelerates the construction of electrified railways in China, particularly the construction of high-speed passenger dedicated lines. The positive feeder line and the power supply line of the contact network are important components of the traction power supply system of the electrified railway. The traction substation, the switching station and the subarea station which are distributed along the line are all provided with power supply lines of several kilometers, the lines with longer power supply arms, large gradient and more roundabout curves are provided with parallel lines and reinforcing lines, and the AT power supply mode sections are all provided with positive feeder lines.

At present, positive feeder, power supply line, enhancement line mainly link to each other with the steel shoulder frame through insulator or insulator chain to guarantee not taking place flashover between additional line and the contact net pillar. However, as the required insulation distance increases, the number of the insulation sheets increases, the length of the insulator string or the insulator increases, the safety distance to a cross-line building and other additional wires inevitably increases, the wire clamp is easy to shake, the limiting effect on the additional wires is poor, and the swing of the additional wires is large; and meanwhile, the cost is high.
