Abstract
The utility model relates to a power supply device of an electric power locomotive, and particularly relates to a fuel battery power supply circuit. The fuel battery power supply circuit comprises a fuel battery. The positive electrode and the negative electrode of the fuel battery are respectively connected with a first power supply plug-in connector XS1 and a second power supply plug-in connector XS2. The first power supply plug-in connector XS1 is connected with the anode of a first crystal diode D1. The cathode of the first crystal diode D1 is connected in series with a DC contactor KM and an air breaker QF in turn and then connected with the anode of a second crystal diode D2. The fuel battery power supply circuit is reasonable in design and simple in structure, and can be greatly applied to a new energy fuel battery light rail vehicle.
Description
Technical field
The utility model relates to the power supply unit of electric locomotive, is specially a kind of fuel cell-powered circuit.
Background technology
In recent years, people proposed requirements at the higher level to environmental protection, many in order to reduce CO
2the technical research work that discharge and energy savings are object is carried out gradually, and fuel cell also receives much concern as a kind of new technology.Fuel cell be with reproducible hydrogen by the supply unit that reacts and generate electricity with airborne oxygen, its emission is the water that reaction generates, free from environmental pollution, realizes zero discharge.Fuel cell is a kind of new forms of energy that grow up recent years, has domesticly just started to manufacture experimently fuel cells applications in railway locomotive traction power source, and fuel cell locomotive power supply technology is in the research and development application stage.
Summary of the invention
The purpose of this utility model is to provide a kind of power supply circuits of fuel cell.
The utility model is to adopt following technical scheme to realize:
A kind of fuel cell-powered circuit, comprise fuel cell, the positive pole of described fuel cell and negative pole are connected with respectively the first power pluging connection XS1 and second source connector XS2, the anodic bonding of described the first power pluging connection XS1 and first crystal diode D1, the negative electrode of described first crystal diode D1 is in series with D.C. contactor KM, air circuit QF successively, then with the anodic bonding of the second crystal diode D2.
During work, new fuel cell locomotive power supply circuit is starting fuel battery first, started and stable operation after again to external circuit power supply, guarantee fuel cell No Load Start.After fuel cell starting under no load completes, the more external circuit supply of closed D.C. contactor, meet the requirement of fuel cell No Load Start.New fuel cell locomotive power supply circuit guarantees the unidirectional output of fuel cell power energy, and external electric energy can not pour into fuel cell.At fuel cell circuit output and external circuit input, respectively adopt a diode, realize fuel cell power energy one-way flow, prevent that external electric energy from recharging into fuel cell, cause fuel cell to damage.New fuel cell locomotive power supply circuit adopts air circuit to provide overload and short-circuit protection to fuel cell, prevents fuel cell overload.New fuel cell locomotive power supply circuit is used power pluging connection ripe on accumulator loco motive, and circuit connects reliable, pegs graft fast, easy to connect.
The utility model is reasonable in design, simple in structure, and a kind of power supply circuits of fuel cell are provided, and can be advantageously applied on new energy source fuel cell light rail car.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure, 1GB-fuel cell, first and second crystal diode of D1, D2-, first and second power pluging connection of XS1, XS2-, KM-D.C. contactor, QF-air circuit.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is elaborated.
As shown in Figure 1, a kind of fuel cell-powered circuit, comprise fuel cell, the positive pole of described fuel cell and negative pole are connected with respectively the first power pluging connection XS1 and second source connector XS2, the anodic bonding of described the first power pluging connection XS1 and first crystal diode D1, the negative electrode of described first crystal diode D1 is in series with D.C. contactor KM, air circuit QF successively, then with the anodic bonding of the second crystal diode D2.
During concrete use, power pluging connection XS1, XS2, D.C. contactor KM, the equipment such as air circuit QF all can directly be bought from the market.
