Abstract
The invention discloses a pressure-type transformer oil chromatographic analysis standard oil storage device. The pressure-type transformer oil chromatographic analysis standard oil storage device comprises a storage device body, two valves and an internal capsule, wherein the valves include a valve I and a valve II; the capsule is positioned in the storage device body; the connection part of the capsule and the storage device body is provided with the valve II for inflating nitrogen into the capsule; the storage device body is also provided with the valve I for introducing oil in the storage device body. The pressure-type transformer oil chromatographic analysis standard oil storage device provided by the invention solves the difficulties of poor storage effect and short storage time of other storage devices, not only guarantees the deserved storage stability of transformer oil chromatographic analysis standard oil, but also prolongs the period of validity of the standard oil greatly, and also has the characteristics of convenience in use, easiness in carrying, capability of reaching the volume of 20L and the like.
Description
Technical field
The present invention relates to a kind of Chromatographic Analysis of Transformer oil standard oil pressure type save set and method thereof.Belong to electric system field of mechanical technique.
Background technology
Chromatographic Analysis of Transformer oil is the important means that transformer operating condition is judged at present, so Chromatographic Analysis of Transformer oil standard oil is also absolutely necessary.But for Chromatographic Analysis of Transformer oil standard oil not yet find so far can be for a long time, the stable device of preserving, can only join i.e. use, so not only increased workload, repeatedly join oily error simultaneously and also to the judgement of chromatographic data, brought no small impact.
Summary of the invention
Technical matters to be solved by this invention be to provide a kind of can be for a long time and the stable device of preserving Chromatographic Analysis of Transformer oil standard oil.
For solving the problems of the technologies described above, the invention provides a kind of Chromatographic Analysis of Transformer oil standard oil pressure type save set, comprise memory storage, valve one, valve two and capsule, described capsule is positioned at memory storage, described capsule and memory storage junction arrange a valve two, for inflated with nitrogen in capsule, a valve one is also set, for oil-feed in memory storage on described memory storage.
A standard oil pressure type store method, utilizes said apparatus, comprises the following steps:
1) device pre-service: shut-off valve one, open valve two, to inflated with nitrogen in capsule, be initial pressure, nitrogen pressure is 0.01-0.02Mpa, makes so built-in capsule be close to memory storage inwall, then shut-off valve two;
2) oil-feed is preserved: open valve one, by external pressure, standard oil is charged into memory storage, the amount of established standards oil arrives 3/4 of device cumulative volume, and pressure stops oil-feed while being 0.2-0.4MPa, thereby reach the effect that pressure is preserved, the maximum pressure that capsule can bear is 0.6MPa;
3) use of standard oil: open valve one, can automatically oil be discharged by the pressure of built-in capsule.
The beneficial effect that the present invention reaches:
Chromatographic Analysis of Transformer oil standard oil pressure type save set of the present invention make Chromatographic Analysis of Transformer oil standard oil can be for a long time, stable, effectively preserve.Accomplish that once joining oil repeatedly uses, when reducing workload, also guaranteed the unitarity of Chromatographic Analysis of Transformer oil value standard, make to analyze data and more prepare, have comparability, for the safe operation of electrical equipment provides sound assurance.In addition, this device also has easy to use, portable, and capacity can reach the features such as 20L.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated.
As shown in Figure 1, the present invention's principle (be that ki value is larger, the solubleness of gas in transformer oil is more stable) that the solubility factor in transformer oil (ki) increases along with the increase of pressure according to gas reaches the effect that pressure is preserved.A kind of Chromatographic Analysis of Transformer oil standard oil pressure type save set is provided, comprise memory storage 4, valve 1, valve 22 and capsule 3, capsule 3 is positioned at memory storage 4, capsule 3 arranges a valve 22 with memory storage 4 junctions, be used for to the interior inflated with nitrogen of capsule 3, a valve 1 is also set, for to the interior oil-feed of memory storage 4 on memory storage 4.
A standard oil pressure type store method, utilizes said apparatus, comprises the following steps:
1) device pre-service: shut-off valve 1, open valve 22, to the interior inflated with nitrogen of capsule 3, be initial pressure, nitrogen pressure is 0.01-0.02Mpa, makes so built-in capsule 3 be close to memory storage 4 inwalls, then shut-off valve 22;
2) oil-feed is preserved: open valve 1, by external pressure, standard oil is charged into memory storage 4, the amount of established standards oil arrives 3/4 of device cumulative volume, and pressure stops oil-feed while being 0.2-0.4MPa, thereby reach the effect that pressure is preserved, the maximum pressure that capsule 3 can bear is 0.6MPa;
3) use of standard oil: open valve 1, can automatically oil be discharged by the pressure of built-in capsule 3.
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.
Claims (2)
