Description
Technical field
The utility model belongs to transformer oil chromatographic on-line monitoring technique field, relates in particular to a kind of degasser separating for Gas in Oil of Transformer.
Background technology
Present stage, China's power equipment as the application such as generator, transformer, motor trended towards maximize (large), high-pressure trend.Large-scale power transformer is the important converting equipment of electric system, and its running status directly affects the security of system, to Operation Condition of Power Transformers carry out in real time or the on-line monitoring of timing significant.
The fault of power transformer inside is mainly that heat and electric form show, that electric fault or hot stall all can produce gas in oil, the component of Gas in Oil of Transformer and content can be used as the characteristic quantity of transformer fault diagnosis, the component of the oil dissolved gas that fault of different nature produces and content are different, type that accordingly can failure judgement.
One of key link that realizes Gases Dissolved in Transformer Oil on-line monitoring is gas-oil separation technology, i.e. degassed link, and this link directly affects stability and the test accuracy of on-line monitoring equipment operation.
For escaping gas on-Line Monitor Device in transformer oil, apply at present more degas method and mainly contain film permeation and vacuum outgas, comprehensive, the film permeation method gas and oil equilibration time is longer, and vacuum outgas structure is more complicated.
Utility model content
For above-mentioned technical matters, the utility model provides a kind of degasser simple in structure, easy to use, that separate for Gas in Oil of Transformer.
For solving the problems of the technologies described above, the technical scheme that the utility model degasser adopts is, a kind of degasser comprises U-shaped scavenging duct, cellular quartz sieve plate, trap tube and six-way valve, described cellular quartz sieve plate is positioned at the bottom of U-shaped scavenging duct one side, described trap tube comprises quartz ampoule and heating component that described trap tube is contained, described heating component is wrapped on the outer wall of quartz ampoule, the side that described U-shaped scavenging duct has a cellular quartz sieve plate and one end of trap tube are connected respectively on the group interface that six-way valve communicates, the other end of described trap tube is connected on another group interface of six-way valve.
The utility model degasser, divide three steps to concentrate to escaping gas in transformer oil sample: gas purging, trapping, pyrolysis is analysed, finally send into gas chromatographic analysis, thereby reach the simple efficient separated beneficial effect of the Trace Volatile Organic Compounds gas making in oil sample to be analyzed.
Brief description of the drawings
Fig. 1 is the utility model degasser structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is made and being further illustrated.
As shown in the figure, the utility model degasser comprises U-shaped scavenging duct, cellular quartz sieve plate, trap tube and six-way valve, described cellular quartz sieve plate is positioned at the bottom of U-shaped scavenging duct one side, described trap tube comprises quartz ampoule and heating component that described trap tube is contained, described heating component is wrapped on the outer wall of quartz ampoule, the side that described U-shaped scavenging duct has a cellular quartz sieve plate and one end of trap tube are connected respectively on the group interface that six-way valve communicates, and the other end of described trap tube is connected on another group interface of six-way valve.
Carrier gas line connects the carrier gas inlet 4 of U-shaped scavenging duct 1, cellular quartz pipe sieve plate 2 is equipped with in other end bottom at U-shaped scavenging duct 1, oil sample to be measured is housed on sieve plate 2, the outlet 6 of U-shaped scavenging duct 1 is through one end of the B of stainless-steel tube, six-way valve 7 end, C end, connection trap tube 3, the other end of trap tube 3 is emptying through the F of six-way valve 7 end, A end, E termination carrier gas 8 for chromatographic column of six-way valve 7, the entrance 9 of D termination chromatographic column.
Cellular quartz sieve plate 2 is porous sieve plates that multi beam quartz glass tube are sintered together to formation.
Trap tube 3 is the stainless-steel tube of diameter 4CM, and sorbing material is inside housed, and it is the quartz ampoule 11 of 12CM that outer cover has diameter, the outer spirality heating component 10 that is wound with of quartz ampoule 11.
The utility model degasser is to divide three steps to concentrate to escaping gas in oil sample, 1, gas purging, 2, trapping, 3, pyrolysis analyses, and sends into gas chromatographic analysis.
First certain oil sample is packed into U-shaped scavenging duct 1, carrier gas is blown into by U-shaped scavenging duct entrance 4, now carrier gas is by the small pore of cellular quartz sieve plate 2, be subject to oily compacting and produce many micro-bubbles, upwards floating from oil sample bottom, when the micro-bubble that contains escaping gas, rise to oil sample liquid level, bubble-break, take the escaping gas in oil sample out of, enter stainless steel pipeline from the outlet 6 of U-shaped scavenging duct 1, be sent to six-way valve 7 and flow to trap tube 3, escaping gas in mixed gas is caught collector 3 and is adsorbed, and the carrier gas that purges use blows out from trap tube 3 other ends, A outlet end 5 by six-way valve 7 is discharged, by the purging of certain hour, escaping gas in oil sample is all blown out and is adsorbed on trap tube 3 inside, switch six-way valve 7, heating component 10 is switched on power, infrared and the heat radiation producing by quartz ampoule 11, make trap tube 3 reach fast resolution temperature, the organic gas being adsorbed in trap tube 3 is parsed, the carrier gas 8 of using by stratographic analysis is blown into chromatographic column analysis by the gas parsing from chromatographic column entrance 9.
The description of above embodiment is comparatively concrete, detailed; but can not therefore be interpreted as the restriction to this patent scope; it should be noted that; for the person of ordinary skill of the art; without departing from the concept of the premise utility; can also make some distortion and improvement, these all belong to protection domain of the present utility model.
