Description
Technical field
The utility model is related to a kind of oil storage tank, especially it is a kind of can analogue transformer go out the transformer oil spectrum of oil pressure
Monitoring device demarcation oil storage tank.
Background technology
It is that outside continu to press enters transformer insulation oil during transformer oil spectrum monitoring equipment on-line monitoring
Enter in monitoring device and analyzed.However, existing transformer oil spectrum monitoring equipment employed in calibration process be pass
The storage device for being used to store transformer standard oil or oil sample of system, oil sample flow out basic no pressure during oil outlet and produced, cause
The demarcation of transformer oil spectrum monitoring equipment can not be carried out reliably, influence the accurate measurements to transformer oil.
The content of the invention
The utility model is to solve the above-mentioned technical problem present in prior art, there is provided one kind can simulate transformation
Device goes out the transformer oil spectrum monitoring equipment calibration oil storage tank of oil pressure.
Technical solution of the present utility model is：A kind of transformer oil spectrum monitoring equipment calibration oil storage tank, there is oil
Room, piston moving up and down is built-in with grease chamber, the piston rod endoporus of piston upper is fuel feed hole, the oil below piston
There is oil outlet room lower end, has venthole and air admission hole, the venthole and the first magnetic valve positioned at the grease chamber side wall of piston upper
Connect, the air admission hole connects with air intake pump, and the oil outlet is connected by pressure sensor with second solenoid valve, the oil-feed
The magnetic valves of Kong Yu tri- connect, and air intake pump, the first magnetic valve, pressure sensor, second solenoid valve and the 3rd magnetic valve are with
Centre controller connects.
The utility model is simple in construction, ingenious in design, rationally distributed, really can go out oil pressure by analogue transformer, fits
Calibration and usage for various transformer oil spectrum monitoring equipment so that demarcation is reliable, can improve to transformer oil spectrum monitoring
Accuracy rate.
Brief description of the drawings
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
Below in conjunction with brief description of the drawings specific embodiment of the present utility model.As shown in Figure 1：A kind of transformer oil spectrum
Monitoring device demarcation oil storage tank, there is grease chamber 1 same as the prior art, with prior art except that built in grease chamber 1
There is a piston 4 moving up and down, the piston rod endoporus above piston 4 is fuel feed hole 8, and the lower end of grease chamber 1 below piston 4 has
Oil outlet 5, the side wall of grease chamber 1 above piston 4 have venthole 11 and air admission hole 12, the magnetic valve of venthole 11 and first
3 connect, and the air admission hole 12 connects with air intake pump 2, and the oil outlet 5 is connected by pressure sensor 6 with second solenoid valve 7,
The fuel feed hole 8 connects with the 3rd magnetic valve 9, air intake pump 2, the first magnetic valve 3, pressure sensor 6, second solenoid valve 7 and
Three magnetic valves 9 connect with central controller 10, and each device is controlled by central 10 controllers.
The course of work is as follows：
Oil outlet 5 is connected with the oil inlet pipe of transformer oil spectrum monitoring equipment first, the 3rd magnetic valve 9 of control is opened,
Pass through the oiling into grease chamber 1 of fuel feed hole 8.After grease chamber 1 has stored up oil sample, fuel feed hole 8 goes out with transformer oil spectrum monitoring equipment
Oil pipe is connected, and the 3rd magnetic valve 9 is closed, and ensures that fuel feed hole 8 does not circulate oil.Second solenoid valve 7 is opened again, pressure sensor
6 start to detect the oil pressure of oil outlet 5, and central controller 10 controls the magnetic valve 3 of air intake pump 2 and first to work according to pressure signal, when
When pressure is less than arranges value, the first magnetic valve 3 is closed, opens air intake pump 2, to the top confined space supercharging of grease chamber 1, works as pressure value
During more than arranges value, air intake pump 2 is closed, the first magnetic valve 3 is opened, to the top confined space release of pressure of grease chamber 1, and so on controls
System, ensure oil outlet oil pressure in the range of required setting, i.e., analogue transformer goes out the oil sample pressure that oil pressure will store up in grease chamber 1
Enter transformer oil spectrum monitoring equipment.
