Problems solved by technology

[0004] At present, in order to reduce transformer problems, the transformer oil is regularly sampled and analyzed to ensure that it can work stably for a long time. Conventional sampling is carried out in glass containers. However, in this way, the transformer oil is in contact with the air and is easily affected by pollution. analysis results

Abstract

The invention relates to a transformer oil sampling storage bag. The transformer oil sampling storage bag comprises a sampling bag and a switch mechanism which is in sealing connection to the samplingbag (1), wherein the sampling bag comprises a bag body; a sealing edge, an inner sealing edge and a sealing hole are arranged on the bag body in a sealing mode; the switch mechanism comprises a sealing nozzle which is in sealing connection to the sealing hole; a supporting plate is arranged on the sealing nozzle in parallel; limiting holes are formed in the supporting plate in a penetrating mode,and two groups of rotary wheels are hinged on the supporting plate; rotary type valves are arranged in the rotary wheels; limiting bulges which are matched with the limiting holes are arranged on theside walls of the rotary wheels; oil passing nozzles which communicate with the sampling bag are arranged on the wheel surfaces of the rotary wheels; and limiting plates are separately arranged on the center and the two sides of the supporting plate. The transformer oil sampling storage bag disclosed by the invention is prevented from being in contact with air, and is light and small.

Description

technical field [0001] The invention relates to the technical field of sampling, in particular to a transformer oil sampling storage bag. Background technique [0002] Transformer oil: It is a fractionation product of petroleum, and its main components are compounds such as alkanes, naphthenic saturated hydrocarbons, and aromatic unsaturated hydrocarbons. Commonly known as square shed oil, light yellow transparent liquid, relative density 0.895. Freezing point <-45°C. [0003] Transformer oil is a kind of mineral oil obtained through distillation and refining from natural petroleum. It is a pure and stable liquid natural hydrocarbon with low viscosity, good insulation and good cooling performance obtained by refining the lubricating oil fraction in petroleum with acid and alkali. Compound mixture. Commonly known as square shed oil, light yellow transparent liquid. [0004] At present, in order to reduce transformer problems, the transformer oil is regularly sampled an...
