Description
Technical field
The utility model relates to a kind of supply unit, is specifically related to the rear emergency backup supply unit of a kind of wind turbine generator major network outage, belongs to the appliances power source technical field.
Background technology
Under severe weather conditions (such as typhoon etc.), if the outage of wind energy turbine set current collection circuit, following situation can occur in the blower fan dead electricity: the urgent locking of blower fan hydraulic brake system dead electricity rear braking; Draught fan impeller can not rotate; Yaw system can not correctly navigate to windage yaw; Can cause the large parts damages such as blade when wind speed is larger, even has and take risk.So back-up power apparatus is after the outage of wind turbine generator major network, guarantee that the critical piece of major network normally moves, reduces the indispensable device of the risk of large parts damages.Yet dragons and fishes jumbled together for supply unit in the market, not only volume is large, capacity is little, and there is no the supply unit of powering for wind turbine generator specially.
The utility model content
For solving the deficiencies in the prior art, the purpose of this utility model be to provide a kind of simple in structure, practical, easy for installation, volume is small and exquisite, capacity is large and special emergency backup supply unit of powering for wind turbine generator.
In order to realize above-mentioned target, the utility model adopts following technical scheme:
A kind of wind turbine generator emergency backup supply unit, comprise: the back-up source main body, power input line, power supply output line, be arranged on the switch on power supply output line, it is characterized in that, also comprise: the outage detection device that is arranged on Monitoring Line and is connected with switching signal, the aforementioned power source output line is connected with the blower fan critical piece, is provided with diode on power input line.
Aforesaid wind turbine generator emergency backup supply unit is characterized in that the input/output port of aforementioned outage detection device has photoelectric insulating protection device.
Aforesaid wind turbine generator emergency backup supply unit, is characterized in that, on aforementioned outage detection device, is connected with alarm.
Aforesaid wind turbine generator emergency backup supply unit is characterized in that aforementioned back-up source main body is batteries.
Aforesaid wind turbine generator emergency backup supply unit, is characterized in that, aforementioned batteries adopts supply/electric discharge of the mode work of floating charge.
Usefulness of the present utility model is: simple in structure, and practicality, easy for installation; Volume is small and exquisite, and capacity is large, and power-on time can remain on 8 hours; Photoelectric insulating protection device can effectively prevent thunderbolt, static and impulse disturbances; Alarm can make the staff find in time powering-off state, extremely easy to use.
The accompanying drawing explanation
Fig. 1 is the composition schematic diagram of a specific embodiment of wind turbine generator emergency backup supply unit of the present utility model.
The implication of Reference numeral in figure: 1-back-up source main body, 2-power input line, 3-power supply output line, 4-switch, 5-outage detection device, 6-diode, 7-photoelectric insulating protection device, 8-alarm.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is done to concrete introduction.
With reference to Fig. 1, wind turbine generator emergency backup supply unit of the present utility model comprises: back-up source main body 1, power input line 2, power supply output line 3, be arranged on the switch 4 on power supply output line 3, and be arranged on Monitoring Line and the outage detection device 5 be connected with switch 4 signals.Wherein, power supply output line 3 is connected with the blower fan critical piece, miscellaneous part is not powered, after the outage of wind turbine generator major network, standby power supply device can guarantee that the critical piece of major network normally moves, and reduces the risk of large parts damages, and power-on time can remain on 8 hours; In addition, be provided with diode 6 on power input line 2, only allow the electric current one-way conduction.
As a kind of preferred scheme, the input/output port of outage detection device 5 has photoelectric insulating protection device 7, can effectively prevent thunderbolt, static and impulse disturbances, guarantees to resolve the accuracy of photodetector 5 detections and the fail safe of use.
More preferably, be connected with alarm 8 on outage detection device 5.Alarm 8 can make the staff find in time powering-off state, greatly facilitates use.
Emergency backup supply unit of the present utility model, its back-up source main body 1 is batteries, not only volume is small and exquisite, and capacity is large, power-on time can remain on 8 hours, after the outage of wind turbine generator major network, can effectively guarantee that the critical piece of major network normally moves, reduces the risk of large parts damages.
As a kind of preferred scheme, batteries adopts supply/electric discharge of the mode work of floating charge.Batteries fluctuates up and down with power line voltage and is discharged and recharged, when the light and power line voltage of load is higher, batteries is charged, when load is heavier or power supply meets accident while interrupting, batteries is discharged, and shares part or all of load.Like this, batteries just plays pressure stabilization function, and in stand-by state.
It should be noted that, above-described embodiment does not limit the utility model in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection range of the present utility model.
