Further, the UPS of output end connection Wind turbines configuration be provided with the direct current be spaced apart, rectification unit,
Inversion unit；The upper wind-driven generator, which assembles, is equipped with the personal goddess of lightning's lines of exchange 400V and emergency bus, and emergency bus is by wind-powered electricity generation
The UPS accumulators outlet direct current that the accumulator of the UPS of crew qiting is configured through Wind turbines is spaced apart, inversion unit is powered；Wind-powered electricity generation
The accumulator of the UPS of crew qiting is spaced apart by the rectified unit of the personal goddess of lightning's lines of exchange 400V, direct current to charge.
Further, the accumulator of the UPS of the output end connection Wind turbines configuration is configured with battery check device.
Outgoing line side setting " house dog " device, and UPS remaining electricity is started with this of the utility model in looped network cabinet breaker
Amount output, supplies ring main unit circuitbreaker control power supply, enables operations staff's operating breaker in the distance, solve big islet operation
The distant place control problem that pattern apparatus for lower wind generating set is powered in turn, in turn power-on time can arbitrarily set, not by UPS capacity
Limitation, increases operational flexibility, reduces construction investment.
Description of the drawings
Fig. 1 is the utility model offshore wind turbine in-line power key wiring diagram.
Specific implementation mode
As shown in Figure 1, wind-driven generator 1, when normal operation generates electricity can be through 690V outlet breakers 2 and step-up transformer
After 3 boostings, it is pooled in 35kV extra large cables circuit 5 by Wind turbines ring main unit 4, and electric energy is sent to offshore boosting station.Boosting
3 low-pressure side of transformer is equipped with house transformator 7, is arranged and exchanges the personal goddess of lightning's lines 8 of 400V, the UPS 10 of Wind turbines configuration, if
There are rectification unit 1001, inversion unit 1002 and direct current to be spaced apart 1003 three parts, output to alternating current 220V emergency bus 9.This
In utility model example, in the access of Wind turbines ring main unit 4 for detecting " house dog " dress whether 401 outgoing line side of breaker charges
6 are set, " house dog " device is made of a voltage transformer 601 and 602 two parts of " house dog " relay.
The 401 outside connection of side and Wind turbines looped network cabinet breaker of voltage transformer 601, voltage transformer 601
Secondary side concatenates relay 602, and the accumulator of the UPS10 of the output end connection Wind turbines configuration of relay 602 exports direct current
Air switch 1003.
The breaker 401 is connect with personal goddess of lightning's line 8, emergency bus 9, obtains operation power.
The accumulator for the UPS10 that the accumulator for the UPS10 that emergency bus 9 is configured by Wind turbines is configured through Wind turbines goes out
Mouth direct current air switch 1003, inversion unit 1002 are powered；The accumulator of UPS10 is by exchanging the rectified list of the personal goddess of lightning's lines of 400V
Member 1001, direct current air switch 1003 charge.
The present embodiment operation principle is：Under big islet operation pattern, when offshore boosting station diesel engine unit passes through the seas 35kV
After the completion of back light photoelectric compound cable is powered to the Wind turbines, by operations staff's remote operation by 401 separating brake of breaker, 400V is certainly
8 dead electricity of electricity consumption busbar, UPS 10 powers to emergency bus 9, when battery check device detects 10 accumulator remaining capacities of UPS
When 20%, UPS 10 and tripping accumulator outlet directing air switch 1003 are voluntarily closed.When offshore boosting station diesel engine unit needs
Again it is rotated to when powering to the Wind turbines, voltage transformer 601 detects that 35kV circuits have charged, voltage transformer 601
" house dog " relay 602 that secondary side is concatenated acts, and one pair of contact of output goes driving 10 accumulators of UPS outlet direct current empty
Air cock 1003 closes a floodgate and starts UPS 10, makes the remaining capacity of UPS 10 continue to discharge to emergency bus 9, breaker 401 has
It after standby operation power, is closed a floodgate by operations staff remote operation 35kV breakers 401, diesel engine unit is restored to Wind turbines 400V certainly
Electricity consumption busbar 8 is powered, and is charged simultaneously to UPS 10, into next rotational cycle.
The foregoing is merely the structure features of specific embodiment of the utility model, but the utility model to be not limited to
This, any those skilled in the art in the field of the utility model, made by changes or modifications all cover it is new in this practicality
Among the protection domain of type.
