Abstract

The application provides a power transmission system, comprising: a power supply source and a transmitting electrode which are arranged on a ground, a receiving electrode arranged at the bottom of a vehicle, and a power conversion apparatus and a power-consuming appliance which are arranged on the vehicle, wherein the receiving electrode is a curved electrode; the curved surface of the receiving electrode has downward radian; the power supply source is connected with the transmitting electrode; the transmitting electrode and the receiving electrode form an interactive magnetic field under theaction of alternating current; the power conversion apparatus is connected with the receiving electrode and the power-consuming appliance. The power transmission system according to the technical scheme has high power transmission efficiency and low electromagnetic radiation influence.

Description

technical field [0001] The present application relates to the technical field of vehicles, in particular to an electric energy transmission system. Background technique [0002] At the present stage, electric trains, locomotives or urban rail vehicles mostly realize power transmission through catenary and the third rail, which means that as long as the vehicle needs to run, it needs to lay as long as the current receiving line, and at the same time, it is necessary to build supporting utility poles, etc. Infrastructure not only occupies a large urban space, affects the city's beauty, but also poses a large safety hazard. [0003] In the prior art, the electromagnetic induction non-contact power supply method can be used to provide traction power for the vehicle by laying a power supply device on the ground along the line. Specifically, the induction system installed on the ground is powered on when a vehicle is detected passing by, and the magnetic field generated by the co...
