Description
Technical Field
The invention relates to the technical field of rail transit, in particular to an electric sectioning device at a single turnout.
Background
The turnout is special track equipment, which not only influences the running safety of the train, but also has shorter service life than other equipment, and the on-site maintenance workload is large. The single turnout most commonly used in China has a straight main line and a lateral line which is branched from the main line to the left or the right, and is also called as a left turnout and a right turnout, and the number of the single turnout accounts for more than 90 percent of the total number of various turnouts.
The electric railway contact network power sectioning device is of a structure that a middle insulating rod is used as a main supporting stress piece, and 4 attached metal sliding plates are used as guide rails for a locomotive pantograph to smoothly pass through. The air gap formed by the insulating rod and the sliding plate guide rail achieves the purpose of electrically isolating the electrified bodies at the two ends of the sectional insulator. With the increase of the altitude, the creepage distance of the insulating rod or the air gap is corrected and increased so as to meet the requirement of the electrical insulation of the system. This increases the risk of bowing when the locomotive passes; the manufacturing and purchasing cost is increased, and the operation and maintenance workload is increased.
