Abstract
The utility model discloses an auxiliary power supply system for an urban rail transit vehicle, which comprises a train power supply bus (1), an auxiliary power supply (2) and an isolation three-phase AC contactor (3). One auxiliary power supply (2) is mounted in each carriage of a train; the auxiliary power supply and the power supply bus form a parallel network to load and supply power for the train; and the isolation three-phase AC contactor (3) is mounted on the power supply bus (1) at least. The contactor (3) is in the closed state when the system is in the normal running state; and a switch controlling device is arranged in the auxiliary power supply (2). Therefore, the contactor is switched off if the grounding of the train bus or the short-circuit fault are detected; and the other auxiliary power supplies can normally supply power. Likewise, if any one auxiliary power supply is in fault, the switch controlling device in the auxiliary power supply is switched off to realize isolation between the auxiliary power supply and the train power supply bus, thereby achieving the purpose of improvement of the train operation reliability.
Description
Technical field
The utility model has related to a kind of vehicle auxiliary power supply system, especially for the auxiliary power supply system of urban rail transit vehicles.
Background technology
In " electric locomotive technology " the 24th volume the 3rd interim " city underground and light rail vehicle ancillary system summary " literary composition of publishing July 20 calendar year 2001 the city rail vehicle auxiliary power supply system is described, its design plan of describing the city rail vehicle auxiliary power supply system mainly contains two kinds of forms:
1, concentration supply power: on the vehicle at train two, respectively establish an accessory feed, respectively to half train power supply.Establish one group of expansion power supply three-phase ac contactor between two accessory feeds, normality when an accessory feed fault, can be expanded power supply by closed contactless switch for disconnecting.Though can because power supply capacity is not enough, will cause full train need excise the load of half this moment to full train power supply; But when train power supply busbar grounding or short trouble the time, then whole auxiliary power supply system is paralysed, thereby influences the reliability of whole electric power system.
2, decentralized power-supply: each joint at train is provided with an accessory feed on car, all accessory feeds by bus to full train power supply.This scheme has had improvement than centrally connected power supply, owing to adopt dispersed placement, redundancy is better, any accessory feed fault, remaining accessory feed capacity is still bigger, still can guarantee supply regular power, and more accessory feed breaks down, the also classification successively of load of excision has had good improvement than centrally connected power supply.But decentralized power-supply also has deficiency: in case ground connection, short trouble appear in power supply buses, then whole auxiliary power supply system is paralysed, thereby also influences the reliability of whole electric power system.
The master cock device of supply unit often adopts power electronic devices, and it has mainly experienced the evolution of thyristor (SRC), high power transistor (GTR, BJT), turn-off thyristor (GT0) and insulated gate bipolar transistor (IGBT).Because the IGBT device belongs to the full-controlled switch device that voltage drives, pulse switch frequency height, performance is good, and loss is little, and the self-shield ability is also strong, so the master cock device of supply unit mainly adopts the IGBT module to constitute.
The utility model content
The technical problems to be solved in the utility model provides a kind of urban rail transit vehicles of failure-free more electric power system, and promptly when ground connection, short trouble appearred in power supply buses, vehicle still continued normal operation.
For this reason, the utility model provides a kind of urban rail transit vehicles auxiliary power supply system, and it comprises train power supply bus, accessory feed and isolation three-phase ac contactor, and every joint compartment of described rail traffic vehicles all is equipped with an accessory feed; This accessory feed and described power supply buses form to be incorporated into the power networks train load are powered; At least be equipped with one on the described power supply buses and isolate three-phase ac contactor; Described isolation three-phase ac contactor is in closed position when system's normal operating condition.
The urban rail transit vehicles auxiliary power supply system that provides according to the utility model, if ground connection or short circuit appear in train power supply bus point, disconnect contactless switch, then the bus of normal reach still can continue powering load, keep train and continue operation, avoid train to be rescued; Thereby reach the purpose that improves the train operation reliability.
Described accessory feed inside has the master cock device. like this when any fault of accessory feed own, turn-off by accessory feed in-to-in master cock device, realize isolating with power supply train bus, thereby can other parts on the train power supply bus not had any impact, promptly the auxiliary power supply system except that the fault accessory feed can normally move, thereby reaches the purpose that improves the train operation reliability.
Description of drawings
Fig. 1 is the circuit block diagram of a kind of embodiment of the utility model.
Fig. 2 is the circuit block diagram of the another kind of embodiment of the utility model.
The specific embodiment
As shown in Figure 1, be the circuit block diagram of a kind of embodiment of the utility model urban rail transit vehicles auxiliary power supply system (is example with 6 joint marshalings).This system comprises train power supply bus 1, lays respectively at the accessory feed 2 and an isolation three-phase ac contactor 3 that is positioned at the middle part in every joint compartment, and this accessory feed 2 forms to be incorporated into the power networks with described power supply buses 1 train load is powered; Described isolation three-phase ac contactor 3 is in closed position when system's normal operating condition.As detect train busbar grounding or short trouble appearance, and then disconnect contactless switch, then still have the accessory feed energy supply regular power of half, keep train and continue operation, avoid train to be rescued, thereby reach the purpose that improves the train operation reliability.
As a kind of improvement technology of the present utility model, described accessory feed 2 inside have the master cock device.When any accessory feed 2 et out of orders own, turn-off by accessory feed 2 in-to-in master cock devices, realize isolating with power supply train bus, thereby can other parts on the train power supply bus not had any impact, promptly the auxiliary power supply system except that the fault accessory feed can normally move, thereby reaches the purpose that improves the train operation reliability.
As shown in Figure 2, be the circuit block diagram (is example with 6 joint marshalings) of the another kind of embodiment of the utility model urban rail transit vehicles auxiliary power supply system.This embodiment difference from Example 1 is, is provided with one between every adjacent two joint compartments and isolates three-phase ac contactor 3, i.e. KM1 shown in the figure, KM2, KM2, KM4 and KM5.Like this train power supply bus 1 is divided into 6 sections, it is stronger that tackle the fault ability this moment, short circuit or earth fault appear in certain point arbitrarily on the train power supply bus, when short circuit or ground connection occurring as the train power supply bus on train isolation contactless switch KM2 Na Jieche is installed, AC contactor on this joint car is disconnected, and the accessory feed that blocks on its this section car is exported, realize the isolation of faulty section train power supply bus, auxiliary power supply network on other five joints car can continue normal operation, thereby avoided the paralysis of permutation car auxiliary power supply system and caused train to be rescued, simultaneously can be with multipoint earth or short circuited fault-safety principle, thus the reliability of train operation is improved greatly.
