Embodiment as shown in Figure 1, provides a kind of supply air system, including air inlet pipeline 100, air inlet pipeline 100 into
Wind end is located at the outside of equipment room 600, the outlet air end of air inlet pipeline 100 be located at the inside of equipment room 600 and with equipment room 600
Inside communicate；Fresh air handling units 500, Fresh air handling units 500 are set to the air intake of air inlet pipeline 100；Air quantity adjusts component, air quantity tune
Save component include the first blast regulator 210 and the second blast regulator 220, the first blast regulator 210 for adjust from into
Air pipe line 100 enter equipment room 600 in intake, the second blast regulator 220 be used for adjusts enter Fresh air handling units 500 into
Air quantity；Sensor module, sensor module include first sensor 310 and second sensor 320, and first sensor 310 is used for
Pressure difference between the inside in detection device room 600 and the outside of equipment room 600, second sensor 320 is for detecting the first air quantity tune
Save the both ends pressure difference of device 210；And controller 400, the first blast regulator 210, the second blast regulator 220, first sensor
310 and second sensor 320 with controller 400 be electrically connected.
Pass through the setting of first sensor 310 and second sensor 320,310 real-time watch device room 600 of first sensor
Inside and outside differential pressure and obtain the first pressure difference data, the pressure at 320 the first blast regulator of real-time monitoring of second sensor, 210 both ends
Difference simultaneously obtains the second pressure difference data, and the first blast regulator 210 is opened when the first pressure difference data exception and is adjusted by air inlet pipeline
100 enter the intake of equipment room 600, and the second blast regulator 220 is opened when the second pressure difference data exception and is adjusted into new
The intake of blower fan group 500, to guarantee that the air pressure in equipment room 600 keeps stablizing, to guarantee the normal operation of equipment.
In general, the equipment room 600 of marine wind electric field booster stations is designed using positive pressure blast system, and set in booster stations
The meteorologic parameters variation such as wind speed, temperature outside standby room 600 is constant to the positive pressure value in equipment room 600 to be affected.It is conventionally employed
Excess pressure valve over-pressure control, be sent into equipment room 600 in air quantity be it is certain, when be more than preset atmospheric pressure value when, by open more than
Air in pressure valve device for transferring room 600, to maintain the pressure difference inside and outside equipment room 600 to stablize.However, there are two for this kind of way
Kind drawback:
Stablize although one, finally maintaining pressure difference inside and outside equipment room 600, opens when excess pressure valve is exhausted decompression
Through being increased to the air pressure in equipment room 600 to a certain degree, this can more or less be generated the running equipment in equipment room 600
It influences, and it is of short duration unstable to there is a situation where air pressure；
Two, using the way of excess pressure valve exhaust decompression, it is easy to make the air quantity of positive pressure blast system excessive, energy consumption is high, causes
The waste of resource, meanwhile, the service life of positive pressure blast system is also reduced, and increase maintenance cost.
The present embodiment passes through first sensor 310, second sensor 320, the first blast regulator 210 and the second air quantity tune
The setting for saving device 220, when first sensor 310 and second sensor 320 detect abnormal data, feed back to controller 400,
And make that controller 400 controls the first blast regulator 210 respectively and the second blast regulator 220 carries out corresponding intake control
System, to keep the stable gas pressure in equipment room 600.
Further, first sensor 310, which can be, can be used to 600 inner and outer air pressure of detection device room and calculate pressure automatically
The sensor of difference；First sensor 310 is also possible to two sensors that can measure air pressure, and one is set to equipment room 600
