Railway vehicle ground power supply interlocking device and railway vehicle ground power supply access method

Abstract

The invention provides a railway vehicle ground power supply interlocking device and a railway vehicle ground power supply access method. The device comprises a ground power supply module, a vehicle-mounted power supply module, a first interlocking control module, a second interlocking control module and a third interlocking control module, wherein the ground power supply module is used for supplying electric energy of a ground power supply to the vehicle-mounted power supply module; the vehicle-mounted power supply module is used for supplying the electric energy provided by the ground power supply module to a load in a railway vehicle and controlling the connection or disconnection of a power supply bus in the railway vehicle; the first interlocking control module is used for controlling the state of a pantograph of the railway vehicle and the state of a main circuit breaker of the railway vehicle; the second interlocking control module is used for controlling the on-off state of a contactor according to the state information of whether the railway vehicle is connected to the ground power supply or not; and the third interlocking control module is used for controlling whether the ground power supply module provides electric energy or not according to the state of the pantograph of the railway vehicle, the state of the main circuit breaker of the railway vehicle and the on-off state of the contactor.

Description

technical field [0001] The invention relates to the technical field of rail transportation, in particular to a rail vehicle ground power supply interlocking device and a rail vehicle ground power supply access method. Background technique [0002] The auxiliary power supply is provided by the external power supply on the ground when the rail vehicle is in production commissioning, depot test, maintenance, etc. [0003] When the power connector of the rail vehicle is connected to the ground power supply, the risk of electric shock is prone to occur because the power connector is live. In addition, serious sparks will be generated at the moment of insertion. Contents of the invention [0004] The invention provides a ground power supply interlocking device for rail vehicles and a ground power supply access method for rail vehicles, which are used to solve the defect of electric shock risk in the prior art when a rail vehicle is connected to a ground power supply, and to rea...
