Abstract

The invention discloses a ring network cable reel distribution process. The ring network cable reel distribution process includes steps of calculating the minimum height Hmix from the top of a traveling track to a lead of a contact net in a whole wire region according to field measured data; determining the largest diameter Rmax of cable reels according to the Hmix value, the height H0 of a track flat car and the suspension height H1 of the cable reels on a cable paying-off rack; determining the largest axle distance Lmax of the cable reels according to the axle distance L0 of the paying-off rack; determining cable reel distribution length in the region according to measured cable path data in various regions; and distributing the determined cable reel distribution length to the cable reels with the axle distance of Lmax and the diameter of Rmax, and increasing cable distribution quantity of each cable reel to the greatest extent. The quantity of the cable reels and utilization quantity of intermediate heads of cables can be reduced. As the utilization quantity of the intermediate heads of the cables is reduced, fault points of the cables after live operation are reduced, and safety of the ring network cables after live operation is improved.

Description

technical field

[0001] The invention relates to the field of power supply and distribution, in particular to a ring network cable distribution process. Background technique

[0002] The subway ring network cable is called the "aorta" of the subway power supply system. It provides a steady stream of reliable electric energy for the core systems of subway electric locomotives, ventilation and air conditioning, lighting power, etc., and is the power source for the effective operation of the entire subway system. Therefore, the construction quality level of the ring network cable directly affects the safety and reliability of the subway system operation, and the ring network cable distribution process is the core part of the ring network cable construction. The length of the cable distribution plate and the size of the disk diameter directly affect The efficiency of cable laying and the safety and reliability of cables after live operation.

[0003] The existing ring network ca...
