Abstract
The invention discloses a transformer oil chromatographic analysis sampling device. The transformer oil chromatographic analysis sampling device is characterized by comprising a sampling container and an opening plug at the opening part of the sampling container, wherein the opening plug is provided with a bottom-through hose and an overflow pipe which are respectively provided with a hose sealing clip. The transformer oil chromatographic analysis sampling container provided by the invention solves the difficulties of poor sealing effect and short period of validity of samples of a chromatographic analysis sampling container, has favorable seal property, can achieve the storage time of more than half a year, and is more convenient to sample and more rapid and easier in transportation compared with an original glass container.
Description
Technical field
The present invention relates to a kind of Chromatographic Analysis of Transformer oil sampling apparatus and method thereof.Belong to electric system applied technical field.
Background technology
Basic wide-necked bottle and the 100ml glass syringe of using of Chromatographic Analysis of Transformer oil sampling at present, adopt wide-necked bottle first cannot realize hermetically sealed sampling, secondly sometimes even do not get the full stratographic analysis test that cannot continue with regard to having caused sample fails in transportation; Though adopt syringe sampling substantially to meet the requirement of hermetically sealed employing, sometimes because the phenomenons such as nook closing member jam, gas leakage easily cause data accuracy low, thereby affect later stage judgement.The reliability that this has had a strong impact on Chromatographic Analysis of Transformer oil result, causes data to have no laws to follow, and cannot judge accurately the operation conditions of equipment.
Summary of the invention
Technical matters to be solved by this invention is to provide a kind of Chromatographic Analysis of Transformer oil sampling apparatus and method thereof of the sampling of sealing completely.
For solving the problems of the technologies described above, the invention provides a kind of Chromatographic Analysis of Transformer oil sampling apparatus, comprise a sampling container, be arranged on the opening plug of sampling container opening part, described opening arranges the flexible pipe of the logical end and a run-down pipe beyond the Great Wall, on flexible pipe of the described logical end and run-down pipe, a flexible pipe sealed card is all set.
Above-mentioned sampling container adopts aluminum-plastic composite membrane press seal, and capacity can reach 200 milliliters.
A method of sampling, utilizes above-mentioned device, comprises the following steps:
1) clean sampling container: the outside port of flexible pipe is connected with transformer sample tap by emulsion tube by the logical end, open two flexible pipe sealed cards simultaneously, then open transformer sample cock, start to drain the oil, after oil sample is full of sampling container, run-down pipe starts to have oil spill to go out, and continues 3-5 minute, reaches the effect of cleaning sampling container;
2) collected specimens: after having cleaned sampling container, close two flexible pipe sealed cards simultaneously, close transformer sample cock, sampling container is removed from transformer sample tap, complete sample collection;
3) use of sampling container: the sampling container of having adopted after sample is enclosed within the outside port of run-down pipe in use with emulsion tube, open the flexible pipe sealed card on run-down pipe, after extruding, oil sample can flow out gently.
The beneficial effect that the present invention reaches:
Chromatographic Analysis of Transformer oil sampling container of the present invention has been realized the requirement of hermetically sealed sampling completely, a plurality of technological difficulties such as the sample data accuracy that solved that sampling container sealing effectiveness was poor in the past, the sample term of validity is short, the sample distortion because causing in transportation, syringe nook closing member jam, gas leakage etc. causes is low, have good sealing, holding time can reach half a year above, easy to use, transport the features such as quick.Use this Chromatographic Analysis of Transformer oil sampling container sampling, can effectively reduce the various errors that cause in sampling process, guaranteed the authenticity of stratographic analysis sample, thereby made chromatographic data of transformer have rule to follow, also the safe operation for transformer provides sound assurance.
Accompanying drawing explanation
Fig. 1 is Chromatographic Analysis of Transformer oil sampling apparatus structural representation of the present invention.

A method of sampling, utilizes above-mentioned device, comprises the following steps:
1) clean sampling container: the outside port of flexible pipe of the logical end 3 is connected with transformer sample tap by emulsion tube, open two flexible pipe sealed cards 5 simultaneously, then open transformer sample cock, start to drain the oil, after oil sample is full of sampling container 1, run-down pipe 4 starts to have oil spill to go out, and continues 3-5 minute, reaches the effect of cleaning sampling container 1;
2) collected specimens: after having cleaned sampling container 1, close two flexible pipe sealed cards 5 simultaneously, close transformer sample cock, sampling container 1 is removed from transformer sample tap, complete sample collection;
3) use of sampling container: the sampling container 1 of having adopted after sample is enclosed within the outside port of run-down pipe 4 in use with emulsion tube, open the flexible pipe sealed card 5 on run-down pipe 4, after extruding, oil sample can flow out gently.
Below with preferred embodiment, disclose the present invention, so it is not intended to limiting the invention, all take to be equal to replace or technical scheme that the scheme of equivalent transformation obtains, all drop in protection scope of the present invention.
