Embodiment Construction

[0012] The present invention will be further described below in conjunction with the accompanying drawings.

[0013] Such as figure 1 As shown, the present invention achieves the effect of pressure preservation based on the principle that the solubility coefficient (ki) of gas in transformer oil increases with the increase of pressure (that is, the larger the value of ki, the more stable the solubility of gas in transformer oil) . Provide a transformer oil chromatographic analysis standard oil pressure storage device, including a storage device 4, a valve 1, a valve 2 and a capsule 3, the capsule 3 is located in the storage device 4, and a valve 2 is set at the connection between the capsule 3 and the storage device 4 2. It is used to fill the capsule 3 with nitrogen gas. The storage device 4 is also provided with a valve 1 for feeding oil into the storage device 4 .

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 [0001] The invention relates to a transformer oil chromatographic analysis standard oil pressure storage device and a method thereof. It belongs to the technical field of power system machinery. Background technique [0002] At present, the chromatographic analysis of transformer oil is an important means to judge the operating conditions of transformers, so the chromatographic analysis of transformer oil standard oil is also essential. However, there is no long-term and stable storage device for transformer oil chromatographic analysis standard oil. It can only be prepared and used immediately. This not only increases the workload, but also brings errors to the judgment of chromatographic data No small impact. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a device capable of long-term and stable storage of transformer oil chromatographic analysis standard oil. [0004] In order to solve the ...
