In the past, organic chlorine nonflammable oil (polychlorinated diphenyl) was used as a nonflammable insulating oil, but its use is prohibited in countries where environmental pollution caused by this oil is a problem. For this reason, in order to make electrical equipment flame retardant, consideration is being given to adopting a dry rim method that does not use insulating oil or an insulation method that uses an inert liquid or inert gas. For oil-filled electrical equipment, especially small-capacity vehicle transformers and power distribution transformers, silicone oil (dimethylsiloxane) with a relatively low viscosity (about 50 cElt at room temperature) is generally used. In addition, among mineral oil and type insulating oils, oils made of high molecular weight hydrocarbons have a 71 flash point strength of 0 and have been partially put into practical use for the purpose of making oil-filled electrical equipment flame retardant.

Among these insulating oils, silicone oil has a high flash point and exhibits self-extinguishing properties due to the silicon oxide (Sins) produced during combustion. At present, its use is limited to low-voltage, medium- and small-capacity electrical equipment because of its high performance and high price. Also, the flash point of high molecular weight hydrocarbon oil is normal! Enkyoku (ASTMD92)

* The table provided by asTMD 9jt shows the flash points of various insulating oils, and rapeseed oil has a higher flash point than silicone oils and high molecular weight hydrocarbon oils. Figure 1 shows the viscosity characteristics of various insulating oils. Figure 6 shows that rapeseed oil has a higher viscosity than ordinary mineral oil, but lower viscosity than commercially available high molecular weight hydrocarbon oils or silicone oils at high temperatures. Figures 2 and 8 show the dielectric loss tangent of rapeseed oil and high molecular weight hydrocarbon oil, ta
The temperature dependence of nJ and resistivity p is shown. It can be seen that the tanJ and ρ of rapeseed oil are at a level sufficient to allow use as an insulating oil. Regarding gas properties, as shown in Figure 4, while silicone oil and high molecular weight hydrocarbon oil generate gas, rapeseed oil has strong gas absorption properties and is excellent in terms of electric field stability. I know that there is.
