Embodiment Construction

[0013] Now combined with figure 1 Attached Figure 4 To further explain the invention, such as image 3 Shown is the principle diagram of train power supply control in a 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 The ability of the train to supply electricity. LGU1 and LGU2 are two sets of train power supply devices on power car 1. The train power supply and distribution cabinet is mainly used to realize the power distribution management of train power supply. KM1, KM2 and KM3 are contactors that realize the power supply and distribution management of trains. In this mode, the load of the carriage 3 is small, and a power car can supply power to the carriage to meet the needs of the carriage 3. Such as Figure 4 Shown is the principle diagram of train power supply control in the marshalling mode of 1 power car + n cars + 1 power car (16≥n≥0). Since power ca...

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 for power centralized EMUs, in particular to a flexible grouping power centralized EMU train power supply control method. Background technique [0002] The power centralized EMU is a more economical and stronger EMU train, and its operation and maintenance costs are superior to that of the traditional EMU. The difference between the power centralized EMU and the power decentralized EMU is mainly that the power of the power centralized EMU is concentrated on the power car, and the unpowered carriages are drawn by the power car and used in fixed formations. The main power equipment is also concentrated in the power car. No passengers are carried on the power car. There is no power equipment on the control car, but only plays the role of controlling the operation of the entire train of EMUs, and the passengers are carried on the control car. The marshalling type of the power centralized EMU ...
