Abstract

The invention discloses a feed module transition device for an electrical vehicle section continuous ground power supply system. A transition unit is located between two power supply units, and a diode in parallel with a resistance is arranged between each power supply unit and the transition unit, and the positive ends of the diodes are connected to conductor elements of the power supply units and the negative ends are connected to the conductor elements of the transition unit. Either the power supply unit is in a state of power supply, so that the transition unit also is in a state of powersupply, so that the length of a slider of a vehicle current collector can be greatly shortened by simply crossing the distance between the power supply units and the transition unit; and when both thepower supply units are in a state of power failure, the transition unit is grounded by the resistances, thus ensuring the safety.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle power supply, and in particular relates to a transition device for a feeder module of an electric vehicle segmented continuous ground power supply system. Background technique [0002] The segmental continuous ground power supply system for electric vehicles in the prior art adopts a modular power feeding scheme. When the vehicle is approaching, with the help of the magnetic pickup device on the vehicle, the conductor element of the module is disconnected from the ground potential, and the positive feeder is connected to the conductor element of the module; when the vehicle is far away, the magnetic force on the vehicle is lost By the action of the pick-up device, the positive feeder is disconnected from the conductor element of the module, and the conductor element of the module is restored to ground potential. A transition unit that does not participate in power supply is set between m...
