Natural ester oils - additional features

Popis výsledku v původním jazyce

Various studies were published concerning different biodegradable fluids as electroinsulating media in the past years. These liquids are to be used e.g. as part of oilpaper insulation systems of transformers. Currently still mainly used mineral oils represent certain danger to the environment. Therefore there has been great emphasis on development of the biodegradable insulating liquid usable in transformers with paper oil insulation. It has been proposed and numerously presented that the natural ester based fluids could be used as substitution for mineral oils eg. in transformers. This type of oil can be manufactured locally. There are many sources for natural ester oils – rapeseed, sunflower, peanut, soybean etc., having good electrical insulation properties and also being easily biodegradable. As stated above, most of its parameters are acceptable or even better compared to the commonly used mineral oil e.g.: Sulphur content, high fire resistance, low toxicity etc. There are still some problems with specific parameters, for example oxidative stability, pour point etc. The aim of this research is to examine and improve the properties of rapeseed oil using different kind of inhibitors. During the last few years we observe the evolution in the field of insulating fluids with focus on biodegradable natural fluids. These fluids are used or to be used e.g. as part of oil-paper insulation systems of transformers. However currently still mainly used mineral oils which represent certain danger to the environment. Therefore there has been great emphasis on the development of the biodegradable insulating fluids usable in power and distribution transformers as these are the most common transformers used in the power grid. It has been proposed and numerously presented that the natural ester fluids based on rapeseed oil etc., could be used as a substitution for mineral oils in transformers. Some remaining problems are discussed in this paper.
