Embodiment 1-5 and comparative example 1-4

[0029] The operating conditions for the process of converting naphtha to aromatics include: a temperature of 520°C and a liquid hourly space velocity of 4 hours -1 , and in the presence of a platinum-supported catalyst, the pressure of hydrogen is 3-18kgf / cm 2 . The aromatic hydrocarbons obtained by the above process have a distillation range of 280-320°C, are a composition of polyalkylated naphthalene and polyalkylated benzene mixed in a volume ratio of 85:15, and have a dynamic viscosity of 5.6cSt at 40°C , the bromine index is 50mg / g, the pour point is -43°C, the content of aromatic hydrocarbons is 99.8% by volume, and it has excellent low temperature fluidity in the high distillation range. The aromatic hydrocarbon composition was quantitatively analyzed by high performance liquid chromatography (HPLC).

[0030] The aliphatic hydrocarbon used to be mixed with the aromatic hydrocarbon is a mixture of aliphatic hydrocarbons containing naphthenes and isoparaffins mixed in a...

Abstract

The invention discloses an electrical insulating oil composite with improved hydrogen-absorbing performance, wherein dutrex containing polyalkyl-naphthalin and polyalkylbenzene is mixed with aliphatic hydrocarbon by certain proportion. Therefore, hydrogen generated by partial discharge at high voltage can be absorbed in short time so as to improve the stability of a capacitor.

Description

[0001] Cross-Referenced Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2007-0108463 filed on October 26, 2007, entitled "Electrical Insulating Oil Composition with Improved Hydrogen Absorption Properties", the entire contents of which are incorporated This application is incorporated by reference. technical field [0003] The present invention relates to an electrical insulating oil composition having improved hydrogen absorbing performance, and more particularly, the present invention relates to an electrical insulating oil composition wherein aromatic hydrocarbons containing polyalkylnaphthalene and polyalkylbenzene Mixed with aliphatic hydrocarbons in a certain ratio, therefore, the hydrogen generated by partial discharge at high voltage can be absorbed in a short time, thus further improving the stability of the capacitor. Background technique [0004] Examples of aromatic hydrocarbons commonly used in electrical insul...
