Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described in further detail.
As shown in Figure 1, the utility model comprises oil circulating pump 1, demand chamber 2, degas chamber 3, Oil-gas Separation chamber 8, collection chamber 7 and electric control gear (not drawing in the drawings), and oil circulating pump 1, demand chamber 2, degas chamber 3, Oil-gas Separation chamber 8, collection chamber 7 connect by pipeline and magnetic valve.Demand chamber 2 upper ends are provided with liquid level sensor 9, and the oil-in A1 of demand chamber 2 upper ends connects oil circulating pump 1 by magnetic valve V1, and oil circulating pump 1 connects insulation fuel tank 12, and the oil-out A3 of demand chamber 2 lower ends connects insulation fuel tank 12 by magnetic valve V2.The degassing hydraulic fluid port A4 of demand chamber 2 lower ends connects degas chamber 3 by magnetic valve V4, and degas chamber 3 is rodless cavities of cylinder; The gas outlet A2 of demand chamber 2 upper ends is by the air inlet B1 of magnetic valve V3 connection 8 lower ends, Oil-gas Separation chamber, and the gas outlet B2 of 8 upper ends, Oil-gas Separation chamber connects four-way 11 by magnetic valve V5.Collection chamber 7 is connected with four-way 11, and collection chamber 7 is rodless cavities of cylinder.Four-way 11 connects carrier gas source by magnetic valve V6, and nitrogen or other inert gas are adopted in carrier gas usually, as the carrier that enters gas analyzer, make Oil-gas Separation chamber 8 not have other gas to sneak into simultaneously, and four-way 11 connects gas analyzer by magnetic valve V7.The piston rod of degas chamber 3 cylinders is connected with the piston rod that the degassing drives cylinder 4, thereby the piston that is driven cylinder 4 drive degas chambers 3 cylinders by the degassing moves up and down, the piston rod of collection chamber 7 cylinders is connected with the piston rod that gas collection drives cylinder 6, thereby the piston that drives collection chambers 7 cylinders by gas collection driving cylinder 6 moves up and down.The degassing drives cylinder 4 and gas collection driving cylinder 6 connects compression pump 5 by magnetic valve V8, V9, V10, V11 respectively.In the present embodiment, magnetic valve V1, V2, V3, V4, V5, V6, V7 are two-position two-way solenoid valve, magnetic valve V8, V9, V10, V11 are two-position three way magnetic valve, the bottom of Oil-gas Separation chamber 8 also is provided with liquid level sensor 10, liquid level sensor 10 is arranged on a certain position of the bottom of Oil-gas Separation chamber 8, when the insulating oil in the Oil-gas Separation chamber 8 reaches the position of liquid level sensor 10, stop Oil-gas Separation, abandon current Oil-gas Separation and gas analysis, because the oily shared volume in the Oil-gas Separation chamber 8 more for a long time, can cause the gas analysis error to be above standard.Electric control gear manufactures and designs by prior art, adopts the action of PLC each magnetic valve of Collaborative Control and whole device.In the utility model, the cylinder of the cylinder of degas chamber 3, collection chamber 7, the degassing drive cylinder 4 and gas collection driving cylinder 6 is general pneumatic element.Insulation fuel tank 12 is not a member of the present utility model.
The course of work of the present utility model: step 1. is opened magnetic valve V1 simultaneously by electric control gear control, magnetic valve V2 and oil circulating pump 1, this moment magnetic valve V3, magnetic valve V4 is in closed condition, insulating oil in the insulation fuel tank 12 is through oil circulating pump 1, magnetic valve V1 enters demand chamber 2, the remaining insulating oil of gas in the demand chamber 2 and degassing operation back last time is entered insulation fuel tank 12 by magnetic valve V2, and make be full of in the demand chamber 2 this test usefulness insulating oil, when liquid level sensor 9 detected insulating oil and is full of demand chamber 2, magnetic valve V1 was closed in electric control gear control, magnetic valve V2 and oil circulating pump 1.
Step 2. is opened magnetic valve V4 simultaneously by electric control gear control, magnetic valve V8 and magnetic valve V10, open magnetic valve V3 then, magnetic valve V5, these 5 magnetic valves stayed open state about one minute, gas in the compression pump 5 is by magnetic valve V8, magnetic valve V10 enters the degassing respectively and drives cylinder 4 and gas collection driving cylinder 6, the piston of the piston of degas chamber 3 cylinders and collection chamber 7 cylinders drives under the driving that cylinder 4 and gas collection drive cylinder 6 in the degassing and moves down (when initial, the piston of degas chamber 3 cylinders and collection chamber 7 cylinders are in upper), so the insulating oil in the demand chamber 2 enters degas chamber 3, simultaneously gas then enters Oil-gas Separation chamber 8 (because the moving down of the piston of the piston of degas chamber 3 cylinders and collection chamber 7 cylinders by magnetic valve V3, in demand chamber 2 and Oil-gas Separation chamber 8, form certain vacuum), enter collection chamber 7 by magnetic valve V5 again behind 8 oil strains of gas process Oil-gas Separation chamber.Close magnetic valve V8, insulating oil in the degas chamber 3 is because the vacuum in demand chamber 2 and the Oil-gas Separation chamber 8, be back to demand chamber 2, when insulating oil is full of demand chamber 2, the signal of liquid level sensor 9 makes electric control gear close magnetic valve V3, the piston of degas chamber 3 cylinders is got back to upper simultaneously, opened magnetic valve V8 and magnetic valve V3 after 10 seconds once again about one minute, make insulating oil be drawn into degas chamber 3 once more, like this repeated multiple times realizes that oil gas separates fully to guarantee insulating oil under the environment of vacuum repeatedly.
Step 3. gas is collected.Open magnetic valve V9 when closing magnetic valve V8, gas in the compression pump 5 enters the degassing by magnetic valve V9 and drives cylinder 4, thereby move on the piston of driving degas chamber 3 cylinders, insulating oil loopback in the degas chamber 3 is gone in the demand chamber 2, closing magnetic valve V3, magnetic valve V4, magnetic valve V5, magnetic valve V10 in turn, open magnetic valve V11 and magnetic valve V7 then, gas in the compression pump 5 enters gas collection by magnetic valve V11 and drives cylinder 6, thereby move on the piston of driving collection chamber 7 cylinders, the gases in the collection chamber 7 are sent in the gas analyzer by magnetic valve V7.
Step 4. is closed magnetic valve V7, open magnetic valve V5 and magnetic valve V6, repeatedly open and close magnetic valve V10 and magnetic valve V11 then, the piston that makes gas collection drive cylinder 6 driving collection chambers 7 cylinders moves up and down repeatedly, in the nitrogen in the carrier gas source or other inert gas suction collection chamber 7 and Oil-gas Separation chamber 8, displacement falls to stay the divided gas flow in the Oil-gas Separation chamber 8, make and be full of nitrogen or other inert gas in the Oil-gas Separation chamber 8, prepare for degassing operation next time is good, the piston of last collection chamber 7 cylinders is in upper, and close magnetic valve V5 and magnetic valve V6, finish the insulating oil degasification process.
