Definitions
- the present invention relates to transformer fluids based on synthetic polyol esters and their use as dielectric insulating fluids for transformers.
- the required properties also include pour point, low acid number, dielectric stability and low sludge formation in the stability test according to LEC.
- good corrosion properties, seal compatibility and, above all, viscosity stability are essential.
- oils used must comply with the standard IEC 61099 "Specifications for unused synthetic organic esters for electricity purposes”. In addition, the flame and focus are important parameters.
- the document EP 0292025 describes electrical devices which are filled with a fire-retardant oil.
- the oil consists of an ester of a polyol with a flame point above 300 ° C.
- Polyol esters are described whose viscosity is still above the desired range.
- no information is given as to whether the polyols with the acid residues used have good biodegradability.
- the object of the present invention was therefore to find compounds as an alternative dielectric insulating liquid for transformers which meet the ICE 61099 standard, show very good biodegradability and have the lowest possible viscosity with high viscosity stability and oxidation stability with the flame and flame resistance corresponding to the standard Have focus.
- the dielectric insulating liquid is based on renewable raw materials and is simple and inexpensive to manufacture.
- a first subject of the present application therefore relates to compositions containing trimethylolpropane ester (TMP) ester of the general formula I.
- TMP trimethylolpropane ester
- the low viscosity which in a preferred embodiment is still equal to or less than 20 mm 2 / s at 40 ° C., leads to an improved heat-dissipating effect and, as a result, to a longer service life of the transformers.
- the low viscosity can be achieved through selected acid components during the esterification.
- the radicals Rl, R2 and R3 in the formula (I) consist of linear or branched alkyl groups having 5 to 11 carbon atoms. It is preferred to use residues with linear or branched alkyl groups with 7 to 9 carbon atoms. The residues must be saturated in order to achieve the necessary oxidation stability. In a polyol ester all residues can be the same, only two residues can be the same or all can be different. Preferred is a distribution of residues with 7 to 9 carbon atoms, which are formed in the esterification of trimethylpropanol with an acid mixture of C8 to CIO fatty acids, the focal point must be above 300 ° C.
- antioxidants and or metal deactivators In order to further improve the properties of the insulating liquid, it is possible and preferred to use antioxidants and or metal deactivators.
- composition according to the invention additionally contains 0.005 to 1.0% by weight of an antioxidant and / or 0.01 to 2.0% by weight of a metal deactivator, based on the ester.
- the preferred amount of antioxidant is between 0.01 and 0.5% by weight and in particular 0.1% by weight, based on the ester.
- the preferred amount of metal deactivator is between 0.1 and 1.0% by weight and in particular 0.1% by weight, based on the ester.
- the antioxidant is preferably selected from the group formed by bis-hydroxytoluene, hydroquinone, 4-tert-butylcatechol, naphthol, phenylnaphthylamines, diphenylamines, phenylthioethers, tocopherols and mixtures of the substances listed.
- the metal activator is preferably organic heterocompounds selected from the group formed by triazoles, toluyltriazoles, dimercaptothiadiazoles and mixtures of the substances listed.
- TMP trimethylolpropane ester
- the transformers are power transformers, distribution transformers, mast transformers, on-load tap changers or changeover switches.
- reaction mixture 250 g of trimethylolpropane are mixed with 850 g of fatty acid under nitrogen. After adding 0.05 g of tin (H) oxalate, the mixture is heated to 230 ° C. with vigorous stirring. From 160 ° C the reaction begins with strong elimination of water. After reaching the reaction temperature of 230 ° C, the reaction is run up to an acid number of 20. Then vacuum is applied at the same temperature and the reaction is completed. It is then cooled and the catalyst is neutralized by adding 50% NaOH solution. The reaction mixture is dried and filtered through Celatom.
- the ester TI is mixed with 0.1% antioxidant and 0.1% metal deactivator, an oxidation test according to IEC 61099 is carried out and the key figures are determined.
- the key figures for a fully additized ester including the dielectric properties according to LEC 61099 are listed here as examples.
