Background technology
It is traditionally used for the storage device of storage transformator standard oil or oil sample, it is semi open model storage or open storage, this storage mode is not suitable for the chromatograph detection to oil, because this kind of mode is it cannot be guaranteed that the gas concentration in oil is constant, if it is desired to keep gas-in-oil concentrations constant, then storage condition is very harsh, causes the raising of carrying cost, and the time simultaneously preserved is also relatively short.Therefore a kind of method or apparatus that can solve the problem that the problems referred to above is needed now.
Summary of the invention
The present invention is to solve the above-mentioned deficiency existing for prior art, it is proposed to a kind of can oil temperature when analogue transformer runs really, pressure, it is adaptable to the various storage devices of standard oil samples for oil chromatography inspection.
nullThe technical solution of the present invention is: the smart storage device of a kind of transformer oil chromatographic detecting device inspection oil,Including grease chamber 1,It is characterized in that: in grease chamber 1, be provided with the piston 3 that motor 2 controls,Pressure transducer 4 it is additionally provided with in grease chamber 1,It is provided with storage container 6 by what drain line 5 was connected with the inner chamber of grease chamber 1,And in drain line 5, it is additionally provided with the first electromagnetic valve 7 and pump 8,Heating module 9 and pressure-temperature sensor module 10 it is provided with in described storage container 6,Storage container 6 is additionally provided with the second electromagnetic valve 11 and the 3rd electromagnetic valve 12,It is provided with circulation line 13 with the inner chamber of described storage container 6 is also connected,Circulation line 13 is additionally provided with the 4th electromagnetic valve 14,The termination traverse piston 3 of described circulation line 13 and the intracavity inter-connection of grease chamber 1,Described smart storage device also includes central controller 15,Described central controller 15 is to motor 2、Pressure transducer 4、First electromagnetic valve 7、Pump 8、Heating module 9、Pressure-temperature sensor module 10、Second electromagnetic valve 11、3rd electromagnetic valve 12 and the 4th electromagnetic valve 14 are uniformly controlled.
The present invention compared with the existing technology, has the advantage that
The smart storage device of the transformer oil chromatographic detecting device inspection oil of this kind of version, its simple in construction, design ingenious, rationally distributed, its problem existing for traditional transformator standard oil or oil sample storage device, design a kind of storage oil sample within it can be heated, the storage container of pressurized treatments, therefore this device can simulate the temperature and pressure of oil sample when transformator runs really, it is adaptable to the storage of the various standard oil samples for oil chromatography inspection.It is by the control of central processing unit, it is achieved that stablizing of the adjustment of oil pressure under airtight condition and oil level in locker room, while ensureing oil dissolved gas stable content, additionally it is possible to extend the storage time.It can be said that it has possessed multiple advantage, being particularly suitable for popularization and application in the art, its market prospect is very wide.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.nullAs shown in Figure 1: the smart storage device of a kind of transformer oil chromatographic detecting device inspection oil,Including grease chamber 1,Piston 3 it is provided with in grease chamber 1,This piston 3 is controlled by motor 2,Pressure transducer 4 it is additionally provided with in grease chamber 1,It is communicated with storage container 6 by drain line 5 with the inner chamber of grease chamber 1,Described drain line 5 is provided with the first electromagnetic valve 7 and pump 8,And in storage container 6, it is additionally provided with heating module 9 and pressure-temperature sensor module 10,Storage container 6 is additionally provided with the second electromagnetic valve 11 and the 3rd electromagnetic valve 12 simultaneously,With the intracavity inter-connection of storage container 6 be additionally provided with circulation line 13,This circulation line 13 is additionally provided with the 4th electromagnetic valve 14,With the intracavity inter-connection of grease chamber 1 after the termination traverse piston 3 of above-mentioned circulation line 13,This smart storage device also includes central controller 15,This central controller 15 is to above-mentioned motor 2、Pressure transducer 4、First electromagnetic valve 7、Pump 8、Heating module 9、Pressure-temperature sensor module 10、Second electromagnetic valve 11、3rd electromagnetic valve 12 and the 4th electromagnetic valve 14 are uniformly controlled.
The work process of the smart storage device of the transformer oil chromatographic detecting device inspection oil of the embodiment of the present invention is as follows: before storage oil sample, first by nitrogen oxygen forming gas, the inner chamber of grease chamber 1 is carried out, first the first electromagnetic valve 7 and the 3rd electromagnetic valve 12 are opened, the container equipped with oil sample is connected at the 3rd electromagnetic valve 12 place, then motor 2 is utilized to control piston 3 up, oil sample is sucked in storage container 6 and grease chamber 1 by the negative pressure produced in grease chamber 1, repeatedly several times after, grease chamber 1 and the oil sample in storage container 6 reach to stop after required amount.Then the first electromagnetic valve 7 and the 4th electromagnetic valve 14 is kept to open, and start pump 8, to slow down the volatilization of oil dissolved gas, to ensure that oil sample is stable, oil sample is at storage container 6, circulation line 13, grease chamber 1, drain line 5 internal recycle, oil sample in grease chamber 1 pressurizes under the effect of piston 3, oil sample in storage container 6 is heated under the effect of heating module 9, the pressure-temperature sensor module 10 being arranged in storage container 6 monitors pressure and the temperature value of oil sample in it at any time, to simulate pressure and the temperature of oil sample in true environment;After oil sample has been simulated, being connected by pipeline with chromatography inspection apparatus by the 3rd electromagnetic valve 12, be input in chromatography inspection apparatus by oil sample and test, the oil sample after inspection returns in storage container 6 again through pipeline and the second electromagnetic valve 11 place.
