Electric sliding contact tracks of ground inflatable streetcar

Abstract

The invention relates to the technical field of traffic power supply equipment, and specifically relates to electric sliding contact tracks of a ground inflatable streetcar, which is characterized by comprising a safety protective box, a hollow sliding track slot body, the electric sliding tracks, pole separating plates, a supply station and an air compression station, wherein the safety protective box is formed by mutually crossing and fixing a base, a left side plate on the left side of the base and a right side plate on the right side of the base, the hollow sliding track slot body is arranged in the safety protective box, inflating holes are horizontally formed in the hollow sliding track slot body, hollow sliding track slots are formed in the side faces or end faces of the hollow sliding track slot body, the adjacent inflating holes are mutually communicated, the air compression station is connected with the inflating holes, three sliding track pole separating grooves are formed in parallel in the hollow sliding track slot body, the pole separating plates are fixed in the sliding track pole separating grooves, the electric sliding tracks are arranged between adjacent pole separating plates, and the electric sliding tracks are connected with the supply station. The electric sliding contact tracks of the ground inflatable streetcar have the advantages of novel structure, safe operation, fast construction progress, no interference signal, no leakage current, low assembly cost and the like.

Description

technical field [0001] The invention relates to the technical field of transportation power supply equipment, in particular to a ground inflatable tram electric slideway. Background technique [0002] As we all know, the existing domestic and foreign power network equipment, from high-speed rail electric locomotives to suburban trams and trolleybuses, all rely on external overhead lines to supply 25 kV ultra-high power to drive. The phenomenon of power failure can cause racing accidents. Second, if there is a war, the enemy can cut off the power supply of the high-speed rail line with graphite bombs or other means. Transformer station, step-down 1500 volt AC series of electrical processing, convert three-phase AC with controllable voltage and frequency, and send it to the traction motor to work, resulting in complex electrical conversion system of equipment, high-end technical level, high power loss, and investment cost big.
