Description
Technical field
The present invention relates to a kind of Chromatographic Analysis of Transformer oil standard oil negative pressure device for formulating and method.Belong to electric system field of mechanical technique.
Background technology
Chromatographic Analysis of Transformer oil standard oil compound method is formulated as master mainly with under atmospheric pressure state greatly at present, and a lot of working standard oil device for formulating only can be prepared the standard oil of single concentration for the Standard Gases of same concentration.Prepare under variable concentrations standard oil condition at needs, often can only change the Standard Gases of variable concentrations, complex operation.Meanwhile, the standard oil making under atmospheric pressure state, the short and difficult preservation of the term of validity.So not only uneconomical but also inconvenient, placing standard oil for a long time if used also may affect the value standard of Chromatographic Analysis of Transformer oil, causes analyzing data and occurs error.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of Chromatographic Analysis of Transformer oil standard oil negative pressure device for formulating and method of utilizing the Standard Gases of same concentration can prepare arbitrarily variable concentrations and easily preserve.
For solving the problems of the technologies described above, the invention provides a kind of Chromatographic Analysis of Transformer oil standard oil negative pressure device for formulating, comprise standard oil preparation fuel tank and a cylinder; The top being provided with on the casing of described standard oil preparation fuel tank in overflow vent, described standard oil preparation fuel tank arranges air bag, described air bag is connected with cylinder, the bottom of described air bag is Standard Gases, the bottom of mark gas is transformer oil, described overflow vent is positioned at Standard Gases and transformer oil intersection, quantitative for transformer oil; Described standard oil preparation fuel tank has been installed linear electric motors, and the two ends of described linear electric motors are connected to standard oil preparation fuel tank bottom and Standard Gases position, fuel tank middle part, for carrying out oil gas circulation.
On above-mentioned cylinder, pressure transducer is installed.
The present invention provides a kind of method of above-mentioned Chromatographic Analysis of Transformer oil standard oil negative pressure preparation simultaneously, utilizes said apparatus, comprises the following steps:
1) oil-feed: blank oil is injected to standard oil preparation fuel tank;
2) oil quantitatively: while having oil spill to go out at the overflow vent place of standard oil preparation fuel tank, oil-feed completes, and the volume of simultaneously setting according to fuel tank has carried out quantitatively blank oil;
3) set preparation pressure: regulate air bag by the piston movement in cylinder, carry out preparation pressure according to pressure transducer and set negative pressure, the i.e. pressure of air bag;
4) standard oil preparation: according to equilibrium principle, the gasbag pressure in standard oil is prepared fuel tank equals the pressure of Standard Gases, starts linear electric motors, carries out oil gas circulation, has prepared while reaching balance.
The beneficial effect that the present invention reaches:
Chromatographic Analysis of Transformer oil standard oil negative pressure device for formulating of the present invention and method, adopted negative pressure preparation principle, by pulling the piston movement in cylinder to produce negative pressure.Utilize negative pressure preparation Chromatographic Analysis of Transformer oil standard oil, can reduce the solubility factor (ki) of gas in transformer oil, ki value is less, and the dissolved gas in oil is more stable, and the standard oil of preparing is more easily preserved; Meanwhile, negative pressure preparation Chromatographic Analysis of Transformer oil standard oil, sets different pressure (negative pressure), and due to the variation of ki value, the concentration range of the standard oil that the Standard Gases of same concentration can make is larger.So both ensured stability and the reliability of standard oil, solved again the problem such as unicity of the standard oil concentration that normal pressure makes, the foundation that provides value to ensure for Chromatographic Analysis of Transformer oil.
