Abstract

The invention discloses a long-life electric power transmission system and method. The system includes a traction substation, a contact line, a train and a return rail that are electrically connected in sequence, and the return rail is electrically connected to the traction substation through the return line. connected to form a current loop; the train includes a control system and at least one power transmission device communicatively connected to the control system, and the power transmission device includes a fixedly connected lifting bow manipulator and a needle tip array electrode; the lift bow manipulator is installed on the top of the train, and its upper end It is fixedly connected with the needle tip array electrode; the needle tip of the needle tip array electrode is in contact with the contact line. The invention changes the traditional contact current receiving mode, adopts electric arc as the medium of energy transmission, and solves the problems of the prior art that the pantograph-catenary system has aggravated impact vibration and frequent arcs, and the service life of the pantograph slide plate is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of pantograph-catenary systems, and in particular relates to a long-life electric energy transmission system and method. Background technique [0002] The only way for a high-speed train to obtain electric energy is through the sliding electrical contact between the pantograph and the catenary (pantograph-catenary system). The quality of the pantograph-catenary relationship directly determines the quality of the train's flow. With the further increase of the running speed of the high-speed train, the coupling vibration of the pantograph-catenary system intensifies, the contact state between the pantograph-catenary system changes from flexible contact to rigid contact, the impact vibration is significantly intensified, the arc between the pantograph-catenary is frequent, and the sliding plate is abnormally worn or even broken, resulting in The service life of pantograph slides is severely reduced, and the rep...
