Description
Technical field
The utility model relates to the improvement of the DC power supply apparatus of secondary device in the electric power control room.
Background technology
Transformer station direct current system is crucial power-supply system, and all protection, automatics and the control loops of electric substation all adopt DC power supply.Transforming station direct current system is a part important in the electrical secondary system, and is most important to the power supply that guarantees electrical network.And problems such as module failure take place in existing DC power supply apparatus quality instability often, need have a power failure when safeguarding, and are extremely inconvenient.Someone is provided with batteries in machine room, in case of need, but the batteries of machine room also only provides the short time power supply.Someone has proposed the movable DC Emergency power supply unit, and it can replace fixed transformer station direct current system apace, realizes the power supply to direct-flow current consumer, and its batteries with machine room is combined, and can realize that no seam powers.But the output of the direct current of this mobile device does not have safeguard measure, and being short-circuited in the wiring of direct-flow current consumer etc. is the situation that the movable DC electric supply installation damages possible occur.
The utility model content
The utility model provides a kind of no seam direct current supply of satisfying the long period at above problem, and the band safeguard measure, can avoid the emergency mobile DC power supply device because of the short circuit damage equipment.
The technical solution of the utility model is: input connects AC power, output connects direct-flow current consumer and standby battery group, it comprises movably housing, be provided with rectification module, direct current output module and control module in the housing, it also is provided with handover module, described handover module comprises K1, K2, K3 three control switchs, charger and fuses, charger is connected in series with K2, K3 is with the K2 that is connected in series, charger and connect, K2, K3 link to each other with K1, the node that links to each other connects fuse, and fuse connects direct-flow current consumer, and charger, K3 connect the standby battery group; Described K1, K2, K3 and charger link to each other with control module respectively, establish the storage chip of the executive program that stores three control switch actions of control in the described control module.
The utility model can also provide charging by accumulators in the direct-flow current consumer power supply, at the storage battery capacity of reaching capacity is, can the automatic disconnection charging, and impaired to prevent equipment, battery.Equipment can automatically switch into battery-driven pattern as breaking down, and the time of storage, backup is provided to machine room.For preventing that short trouble from appearring in the road, back, the utility model is provided with fuse at output, has made things convenient for cut-out direct current output, the protective effect that the utility model is played.
Description of drawings
Fig. 1 is a structural representation block diagram of the present utility model
1 is housing among the figure, the 2nd, and handover module, the 3rd, fuse.
Embodiment
The utility model as shown in Figure 1, input connects AC power, output connects direct-flow current consumer and standby battery group, it comprises movably housing 1, be provided with rectification module, direct current output module and control module in the housing 1, it also is provided with handover module 2, described handover module 2 comprises K1, K2, three control switchs of K3, charger and fuse 3, charger is connected in series with K2, K3 is with the K2 that is connected in series, charger and connect, and K2, K3 link to each other with K1, and the node that links to each other connects fuse 3, fuse 3 connects direct-flow current consumer, and charger, K3 connect the standby battery group; Described K1, K2, K3 and charger link to each other with control module respectively, establish the storage chip of the executive program that stores three control switch actions of control in the described control module.
The utility model operation principle is: when the DC power supply of machine room breaks down, substituted by the utility model.The direct-flow current consumer, the charger that the utility model output are connected machine room connect storage battery, and at this moment, control module instruction K1 closes, K2 closes, K3 opens.After storage battery reached rated capacity, control module was according to the charger feedack, and instruction K2 opens.If there is device to break down in the utility model, high excessively as temperature, control module instruction K1 opens, K3 closes, and is powered by batteries temporarily, after fault is got rid of, recovers normal mode of operation.When faults such as electrical appliance wiring in the machine room is short-circuited, the fuse 3 in the utility model opens circuit, and realizes the protection to the utility model equipment.
