Embodiment Construction

[0013] now attached figure 1 to attach Figure 4 A further description of the invention, such as image 3 Shown is the train power supply control principle diagram of the marshalling mode of 1 power car + n cars + 1 control car (8≥n≥0). Since the control car 5 does not have a train power supply device, the control car 5 does not have Ability to power trains. LGU1 and LGU2 are two sets of train power supply devices on power car 1. The train power distribution cabinet is mainly used to realize the power distribution management of train power supply. KM1, KM2 and KM3 are contactors to realize train power supply distribution management. In this mode, the load of the compartment 3 is relatively small, and a power car can supply power to the compartment to meet the demand of the compartment 3 . Such as Figure 4 Shown is the train power supply control schematic diagram of the marshalling mode of 1 power car + n cars + 1 power car (16≥n≥0). Since power car 1 has a train power sup...

Abstract

The invention discloses a power supply control method for flexible-marshalling power-concentrated D-series high-speed trains. Marshalling modes of power-concentrated D-series high-speed trains comprise long marshalling units and short marshalling units. Each power train is provided with a train power supply device LGU1, a train power supply device LGU2 and a train power distribution cabinet. A contactor KM1 in each train power distribution cabinet controls on and off of the corresponding train power supply device LGU1, a contactor KM3 in each train power distribution cabinet controls on and off of the corresponding train power supply device LGU2, and a contactor KM2 in each train power distribution cabinet controls on and off of the corresponding train power supply device LGU1 and the correspondingly train power supply device LGU2 which is connected with the train power supply device LGU1 in parallel. Each train power distribution cabinet is provided with a marshalling mode switch. When the short marshalling units are selected, the contactors KM1 and KM3 are turned on, the contactors KM2 are turned off, and the train power supply devices LGU1 and LGU2 transmit electric energy to carriages. When the long marshalling units are selected, the contactors KM1 and KM2 are turned on, the contactors KM3 are turned off, and the train power supply devices LGU1 and LGU2 transmit electric energy to the carriages. By means of the power supply control method, the requirement of the carriages of the power-concentrated D-series high-speed trains for train power supply is met, and meanwhile, automatic switching of train power supply control under the flexible marshalling condition is guaranteed.

Description

technical field [0001] The invention relates to the technical field of power supply control technology for centralized power trains, in particular to a power supply control method for flexibly organized power centralized trains. Background technique [0002] The power concentrated EMU is a more economical and more economical EMU train, and its operating and maintenance costs are superior to traditional EMUs. The main difference between the power centralized EMU and the power decentralized EMU is that the power of the power concentrated EMU is concentrated on the power car, and the power car pulls the carriage without power and is used in a fixed formation. The main power equipment is also concentrated in the power car. On, no passengers are carried on the power car. There is no power equipment on the control car, but it only plays the role of controlling the operation of the entire EMU. The control car carries passengers. The formation type of the centralized power EMU is f...
