Abstract
The invention discloses a preparation method for a standard transformer oil sample. The preparation method comprises the steps of quantifying a blank oil sample, degassing the blank oil sample, injecting the blank oil sample into a sealed container, adding quantified gas, fully mixing the quantified gas and the blank oil sample and the like to prepare the standard oil sample of the transformer. The standard transformer oil sample prepared by the method disclosed by the invention can be used as an oil sample standard for standard transmission from the national level to the local level, so that a detection standard can be easily implemented in reality. The preparation method particularly has an obvious standard oil sample effect on extremely high concentration and extremely low concentration.
Description
Technical field
The present invention relates to a kind of preparation method of transformer standard oil sample, especially for the preparation method of the standard transformer oil sample of extremely low concentration and high concentration.
Background technology
In country's " 12 " development plan, using building intelligent grid as key strategy development plan.In intelligent grid construction, can be divided into again both separate and links that is mutually related such as six of intelligent power generation, intelligence transmission of electricity, intelligent power transformation, intelligent power distribution, intelligent power and intelligent schedulings etc.Wherein intelligent power generation link and intelligent power transformation link all be unable to do without important core power equipment: transformer, reactor.As power generation and two kinds of important equipment of power transformation link, their safe and stable operation direct relation the safety and stability of national grid system.So China's power department drops into a large amount of manpowers, fund, equipment the transformer of 220kV above and reactor has been installed additional to on-Line Monitor Device, to emphasis transformation device is carried out to real time on-line monitoring.
Due to the guidance quality of national policy and the market demand, on-line monitoring industry is in the ascendant, but the development of technology must be followed objective law.For standard on-line monitoring market, reinforcement is supervised and checks on this art, State Grid Corporation of China has issued Q/GDW540 series < < converting equipment on-Line Monitor Device inspection specification > > in 2011, wherein second portion (being designated hereinafter simply as < < Q/GDW540.2 > >) content is for Gases Dissolved in Transformer Oil on-Line Monitor Device (hereinafter to be referred as DGA device), to work out specially, the performance index of the various aspects of Gases Dissolved in Transformer Oil device (DGA device) have been set forth comprehensively, comprising for on-Line Monitor Device is is comprehensively tested and assessed and the preparation standard of prerequisite transformer oil sample.
According to the requirement in state net < < Q/GDW540.2 > > standard, draw table 1, as the evaluation frock to on-Line Monitor Device performance index, 11 standard oil samples are prerequisite.But in real work, a lot of testing crew reflection oil samples 2 to oil sample 6 is prepared than being easier to; Oil sample 1, i.e. the oil sample of lowest detectable limit, very difficult preparation is out; Than oil sample 1 more difficult preparation be oil sample 7 to oil sample 11, the H2 of high concentration oil sample, particularly high concentration, CO are difficult to prepare successfully.As table 1.Even if the oil sample easily preparing 2 is to oil sample 6, also there is larger error in expection concentration and the actual concentration reaching, and be difficult for preserving, and easily changes, and do not possess transitivity.
Standard oil sample concentration value (the unit: μ L/L) that table 1 calculates according to the relevant regulations in < < Q/GDW540.2 > >
