Description
Technical field
The utility model relates to subway equipment technical field, especially a kind of novel inversion mixed regeneration braking energy absorption plant.
Background technology
One of mode of braking of subway train is regenerative braking.The great advantage of regenerative braking is energy-conservation, but regenerative electric energy can not used by adjacent train after feeding back to direct current contact line, and when Train Interval is larger, only have fraction regenerative electric energy to be used, unabsorbed energy is consumed by vehicle-mounted brake resistance.When consuming regenerative electric energy by brake resistance, the temperature rise of tunnel and underground station can be brought, increase the load of underground station air-conditioning system, cause a large amount of energy loss, increase operating cost.Inversion feedback absorption techniques arises at the historic moment, and when regenerative braking makes direct current contact line voltage exceed set point, inverter is started working and from DC bus Absorption Current, regeneration direct current energy is reverse into AC energy and is fed back to AC network.But current inversion mixed regeneration braking energy absorption plant radiating effect is not good, and when outdoor temperature is lower, device inside easily produces moisture, and dust and other impurities easily enters, the time one is long, easily causes that internal circuit is aging, short circuit, causes fire.
Utility model content
In order to overcome existing deficiency, the utility model provides a kind of novel inversion mixed regeneration braking energy absorption plant.
The utility model solves the technical scheme that its technical problem adopts: a kind of novel inversion mixed regeneration braking energy absorption plant, comprise cabinet, described cabinet top is provided with thermometer, described bottom of cabinet bulk is provided with drying layer, described drying layer is connected with cabinet by draw-in groove, and described cabinet inwall is provided with two ventilating fans, and described cabinet top is provided with camera, described cabinet lower end is provided with ventilating opening, is provided with dust-separation film in described ventilating opening.
According to another embodiment of the present utility model, comprise further, in described drying layer, be filled with anhydrous cupric sulfate.
According to another embodiment of the present utility model, comprise further, described ventilating fan is connected with thermometer.
The beneficial effects of the utility model are, in this novel inversion mixed regeneration braking energy absorption plant, ventilating fan can effectively be lowered the temperature in device; Drying layer can guarantee that this device moment is in dry environment, dust-separation film in ventilating opening can effectively stop in extraneous dust access to plant, dustfree environment in assurance device, prevent in this device circuit aging, the useful life of extension fixture, and drier anhydrous cupric sulfate can recycle, saving resource.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1-cabinet in figure, 2-drying layer, 3-draw-in groove, 4-ventilating fan, 5-exhaust outlet, 6-dust-separation film, 7-camera, 8-thermometer.
Embodiment
If Fig. 1 is structural representation of the present utility model, a kind of novel inversion mixed regeneration braking energy absorption plant, comprise cabinet 1, described cabinet 1 top is provided with thermometer 8, drying layer 2 is provided with bottom described cabinet 1, anhydrous cupric sulfate is filled with in described drying layer 2, described drying layer 2 is connected with cabinet 1 by draw-in groove 3, described cabinet 1 inwall is provided with two ventilating fans 4, described ventilating fan 4 is connected with thermometer 8, described cabinet 1 top is provided with camera 7, and described cabinet 1 lower end is provided with ventilating opening 5, is provided with dust-separation film 6 in described ventilating opening 5.
When in this novel inversion mixed regeneration braking energy absorption plant, temperature is more than 20 °, ventilating fan 4 controls to open at thermometer 8, dispels the heat to this device inside; When in this novel inversion mixed regeneration braking energy absorption plant, temperature is lower than 20 °, ventilating fan 4 cuts out.When being found that by camera 7 the anhydrous cupric sulfate color transition in drying layer 2 becomes navy blue, drying layer 2 is extracted out bottom cabinet 1, anhydrous cupric sulfate is carried out oven dry to white, then the anhydrous cupric sulfate after drying is filled in drying layer 2, and drying layer 2 is snapped on cabinet 1 by draw-in groove 3.
Claims (3)
1. a novel inversion mixed regeneration braking energy absorption plant, comprise cabinet (1), it is characterized in that, described cabinet (1) top is provided with thermometer (8), described cabinet (1) bottom is provided with drying layer (2), described drying layer (2) is connected with cabinet (1) by draw-in groove (3), described cabinet (1) inwall is provided with two ventilating fans (4), described cabinet (1) top is provided with camera (7), described cabinet (1) lower end is provided with ventilating opening (5), is provided with dust-separation film (6) in described ventilating opening (5).
2. one according to claim 1 novel inversion mixed regeneration braking energy absorption plant, is characterized in that, described drying layer is filled with anhydrous cupric sulfate in (2).
3. one according to claim 1 novel inversion mixed regeneration braking energy absorption plant, is characterized in that, described ventilating fan (4) is connected with thermometer (8).
