چکیده
Electricity companies around the world are constantly seeking ways to provide electricity more safely and efficiently while reducing negative impact on environment. Mineral oils have been most popular transformer insulation, having excellent electrical insulating properties, but many problems such as high flammability, significant cleaning problems, toxic fish wildlife. This paper presents an alternative approach mineral oil: a design that is clean provides better performance environmental benefits. A 50 kVA, 34.5/0.4 kV gas insulated distribution was designed evaluated using COMSOL Multiphysics R410A used insulation material. near-azeotropic mixture of difluoromethane (CH2F2, called R-32) pentafluoro ethane (C2HF5, R-125), which refrigerant in air conditioning applications. It has properties including environmentally friendly, no-ozone depletion, low greenhouse effect, non-explosive non-flammable, First, breakdown voltage selected determined. The electrostatic thermal were investigated simulation results for oil SF6 transformers same model compared. gas-insulated believed equivalent friendly current oil-based transformers.
