Description
Technical field
The invention belongs to device for transformer field, especially relate to a kind of can the oil storage of accurate level monitoring
Cabinet.
Background technology
The usual traverse of oil conservater, above the fuel tank of transformator, is connected with fuel tank with pipeline.Work as transformer oil
During flatulence of heat type, oil is flowed to oil conservater by fuel tank；When transformer oil shrinkage, oil is flowed to fuel tank by oil conservater.
Existing oil conservater is internally provided with corrugated tube, and corrugated tube is turned on ambient atmosphere by pneumostome,
Increase or reduce the pressure change brought with oil conservater inner fluid, corrugated tube can stretch or shrink, logical
Cross corrugated tube and realize the purpose of regulation oil conservater internal memory oil storage liquid volume.Existing corrugated tube is generally by meter
The displacement of amount corrugated tube, the volume that the displacement of corrugated tube is converted into oil conservater inner fluid becomes
Change, carry out the liquid level of measurement monitoring fluid, there is collection corrugated tube displacement inaccurate, error after conversion
Greatly, and with corrugated tube displacement as measurement criteria, the most unreasonable.
Summary of the invention
In view of this, it is contemplated that propose a kind of can the oil conservater of accurate level monitoring, it is possible to respectively
Gather and suck in corrugated tube and the air mass flow of exhalation, to measure changes in air volume in corrugated tube, as
The standard of monitoring oil conservater inner fluid liquid level, more rationally accurately, it is possible to immediately arrive at oil conservater inner fluid
Change in volume, shown liquid level is more accurate.
For reaching above-mentioned purpose, the technical scheme is that and be achieved in that:

The flow information that mass-air-flow sensor and expiratory flow sensor can will gather respectively, grease proofing by insulation
Data wire upload to center processing unit, carry out simple calculating process by center processing unit, will
Air mass flow difference in corrugated tube is converted into the fluid change in volume of oil conservater casing, and is connect by control
The oil level monitor that mouth connects, the accurate oil level of display oil conservater casing.Compared to traditional, by adopting
The shift length of collection corrugated tube, calculates the technology of fluid oil level change, and the displacement parameter gathered is simply
A part of displacement of corrugated tube, it is impossible to react the displacement change of whole corrugated tube, collection result
Inaccurate, cause oil level inaccurate, of the present invention, gather corrugated tube and suck and exhalation air stream
It is poor to measure, and the distance change of W-response corrugated tube, as the standard of monitoring oil conservater inner fluid liquid level, more
Add the most accurately, it is possible to immediately arriving at the change in volume of oil conservater inner fluid, shown liquid level is more accurate.
The sampling sensor that the expiration interface of the present invention is arranged can gather the sample of the gas of exhalation, and energy
Enough carry out oil-containing monitoring, and collection and monitoring result are uploaded to center processing unit, by center processing list
Unit's comparison threshold parameter, once finds that the gas oil content that breathed out exceeds standard, anticipation to bellows bursts,
Flow into the fluid in oil conservater casing, it is possible to control in time to start alarm unit, carry out alarm.
It is arranged on the oil pressure sensor in oil conservater casing, it is possible to monitoring oil pressure, and uploads to center processing
Unit, by center processing unit comparison threshold parameter, once finds that oil pressure is beyond rational scope, it is possible to
Control to start alarm unit, carry out alarm.
The dirt collection mouth that oil conservater box bottom is provided with, it is possible to assemble the impurity in fluid, by the row of opening
Dirty valve, it is possible to the impurity that dirt collection mouth is assembled outwardly is discharged.
