Description
Technical field
The utility model relates to a kind of analyzing and testing equipment, especially a kind of on-Line Monitor Device that is used for online detection and the contained gas componant of Transformer Oil Analysis.
Background technology
Transformer is the visual plant in the electric system, and it is undertaking the transmission and the distribution of electric energy, so its safe and stable operation has significance.Transformer oil is a mineral insulating oil, is a kind of fraction products of oil, and its principal ingredient is the hydrocarbon mixture that one-tenth such as alkane, naphthenic hydrocarbon, aromatic hydrocarbon are grouped into.When oil-filled electrical equipment is under the normal operating condition, the gas flow that oil and solid insulation decomposite is few.Along with the increase of working time, solid insulation shows aging tendency gradually, CO that decomposites and CO
2To increase year by year.When appearance in the transformer was discharged or be overheated, oil or solid insulation decomposition produced some gases.These gases through convection current, diffusion, can constantly be dissolved in the oil in oil, if the amount of gas that produces during greater than the quantity that is dissolved in the oil, gets in gas relays just have some gases.The condition that all gases produces is different, and the kind that produces gas and quantity is with to execute energy outward relevant, like shelf depreciation, through the main generation H of ionic reaction, fracture
2, also can generate gases such as methane, ethene, ethane, acetylene, need separately temperature and energy when generating different gas respectively.When transformer oil generation physics, chemical reaction, follow the generation all gases, and, become the significant gas of quantity through long-term accumulation.These gases that decompose out form bubble and in transformer oil, spread through convection current, constantly are dissolved in the oil.Transformer exists the overheated or discharge property fault of latency can accelerate the speed that these gases produce; Because the composition of failure gas and the order of severity of content and fault type have substantial connection; Through transformer oil dissolved gas content analysis, can know the operation conditions of transformer, combine other related electric tests again; Can judge whether transformer inside exists fault; But also can be further promptly distinguish overheating fault or discharge property fault, judge abort situation, the order of severity and the harmfulness of transformer fault, propose the handled measure according to the character of the difference failure judgement of the type content of fault generating gas composition and gas production rate.So the gas that periodic analysis is dissolved in the transformer oil can be found the inner latency fault that exists of transformer early.
Common way is to utilize vapor-phase chromatography to detect the content of various dissolved gases in the insulating oil now; But each the detection all must be through oil sample collection-such process of oil sample transportation-gas-oil separation-stratographic analysis under this mode; And each link all exists the factor that influences final detection result; Final detection result is existed than mistake, and this can make a big impact to judging the oil-filled equipment inner fault type and the order of severity thereof.In addition, this technology can not detect in real time, and each sense cycle is longer relatively, and fault can not realize continuous on-line monitoring for developing faster, is difficult to give full play to its effect, can not in time grasp the transformer fault development trend.
Summary of the invention
The utility model is to be solved to be exactly can not monitor the transformer oil dissolved gas in real time at present, and detected components is single, is difficult in time find transformer fault, and contained gas H in a kind of online detection and the Transformer Oil Analysis is provided
