Abstract
The utility model discloses a transformer insulation online monitoring device, comprising a gas-oil separator 1 and a chromatographic detection control box 2. The gas-oil separator 1 is arranged in the chromatographic detection control box 2. The transformer online monitoring device with this structure has accurate detection result, easy equipment installation and debugging.
Description
Technical field the utility model relates to the on-Line Monitor Device of a kind of on-Line Monitor Device of power equipment, particularly a kind of transformer,
The existing transformer online monitoring device of background technology comprises that oil-gas separator and chromatogram detect control box, connect by pipeline between the two, oil-gas separator is isolated the fault signature gas that is dissolved in the transformer oil, further separate and sample gas information by the pipeline transmission detection case of falling the chromatogram, again by the special software analytical information, thereby realize the on-line monitoring of transformer.The problem that exists is: it is independent of each other that existing oil-gas separator and chromatogram detect control box, the isolated gas of oil-gas separator inevitably will lose in the transmission course of pipeline, and be subjected to the influence of environment temperature easily, gas might condensation or is contained micro-moisture, makes testing result not accurate enough.
The summary of the invention the purpose of this utility model is to provide a kind of above-mentioned shortcoming, testing result transformer insulated on-line monitoring device accurately that overcomes.
The utility model is achieved in that a kind of transformer insulated on-line monitoring device, comprises that oil-gas separator and chromatogram detect control box, and this oil-gas separator is placed on chromatogram and detects in the control box.
The utility model combines in chromatogram to oil-gas separator and detects control box inside, can in the Monitoring and Controlling case, carry out adjustment according to environment on every side with temperature controller in good time, reduced the influence of environment temperature, the purity of institute's gas production body sample is improved greatly, avoided oil-gas separator to be connected simultaneously with the long distance line that chromatogram detects control box, the sample gas that penetrates pipeline significantly reduces, the content and the air pressure of gas have direct relation, connecting distance shortens, make the pressure of sample gas in pipeline increase, thereby it is steady to have accelerated flow velocity and the flow velocity of gas in pipeline, makes that institute's quantity of information of adopting is abundant, the sampling curve reflection is sensitive, the accuracy height.In addition, equipment is installed, debugging is convenient, is convenient to safeguard.
Below in conjunction with accompanying drawing embodiment of the present utility model is described further.
Appended drawings is the utility model structural representation.
Embodiment as shown in the figure, oil-gas separator 1 places chromatogram to detect control box 2 inside.Oil-gas separator 1 comprises macromolecule oil film 3 and electromagnetism six-way valve 4, chromatogram detects control box 2 and comprises chromatographic column 5, series sensor 6, detector 7, data acquisition unit 8, temperature controller 9, oil-gas separator 1 is connected with transformer fuel outlet valve 11, and chromatogram detects control box 2 and is connected with data processor by connection 10.
Principle of work of the present utility model is: the oil that is dissolved with fault signature gas that transformer fuel outlet valve 11 the flows out chromatogram of at first flowing through detects oil-gas separator 1 in the control box 2, contain macromolecule oil film 3 in the oil-gas separator 1, this ventilated membrane only permeates fault signature gas and impermeable transformer oil, gas molecule side to air chamber from oil spreads, at a certain temperature, behind the certain hour, the gaseous tension of macromolecule oil film 3 both sides tends to balance, reach mobile equilibrium, automatically realized gas-oil separation.The gas that is separated enters electromagnetism six-way valve 4 under the effect of built-in miniature air pump, flow through chromatographic column 5 again under the effect of carrier gas, and mixed gas is separated into six kinds of characteristic gas---H
2, CO, CH
4, C
2H
4, C
2H
2, C

6Then, series sensor 6 detects these six kinds of characteristic gas, the different sensors unit responds characteristic gas separately respectively, the sensing unit of every kind of gas to the sensitivity of detected gas separately apparently higher than remaining gas, some cross one another gas componant is got rid of mushing error, detection H that can be correct by certain software processing method
2, CO, CH

6Six kinds of concentration of dissolved gas.Detector 7 goes out the peak by gas and respectively six component gas is become voltage signal in proper order.Data acquisition unit 8 is uploaded to data processor with the voltage signal that collects by connection 10, data processor carries out quantitative test according to the data of demarcating, calculate the content of each component and total hydrocarbon and rate of growth separately, by fault diagnosis expert system transformer fault is diagnosed again, thus the on-line monitoring of realization transformer.
Chromatogram detects in the control box 2 temperature controller 9 is set, and can do corresponding adjusting according to the variation of environment temperature, can effectively reduce the influence of environment temperature to the gas transmission, guarantees the purity of sample gas.
