Embodiment Construction

[0026] Such as figure 1 As shown, the environment-friendly oil-immersed distribution transformer based on high ignition point vegetable oil of the present invention mainly includes an oil tank and an iron core 2 arranged in the oil tank, windings, insulating paper, insulating plates, transformer oil cooling circulation system and heat dissipation 1, the oil tank is filled with vegetable oil with a flash point higher than 330°C, which is used to replace the mineral insulating oil in the existing oil-immersed distribution transformer as transformer insulating oil. The vegetable oil can be one or a mixture of two or more of rapeseed oil, soybean oil, camellia seed oil and peanut oil. The vegetable oil used in the present invention has the advantage of having a higher ignition point than ordinary mineral oil under the same insulation capacity, and is more suitable for use in on-site power distribution transformers.

Abstract

The invention discloses an environment-friendly oil-immersed distribution transformer based on high ignition point vegetable oil. The oil tank is filled with vegetable oil whose ignition point is higher than 330°C. Existing standard oil-immersed distribution transformers of the same capacity grade using mineral insulating oil are increased by more than 30%; the natural cooling circulation system of transformer oil adopts the inner same-direction and outer one-way corrugated radiator structure; the radiator adopts wave-shaped cold rolling The inner diameter of the steel plate and the oil inlet and outlet of the radiator is more than 30% larger than that of the existing standard oil-immersed distribution transformer of the same capacity grade using mineral insulating oil. The invention has the advantages of safety and reliability, excellent environmental protection performance, unlimited repeated production of raw materials and natural degradation, and can get rid of the existing oil-immersed distribution transformer's dependence on mineral insulating oil.

Description

technical field [0001] The invention relates to a distribution transformer in electric power equipment, in particular to an environment-friendly oil-immersed distribution transformer based on high ignition point vegetable oil. Background technique [0002] With the rapid development of the industrialization process, the demand for energy is increasing, and the energy dominated by mineral resources can no longer fully meet the demand. According to estimates, major mineral resources such as coal and oil will be exhausted in the next 500 years. Energy disputes The world is increasingly tense, so the whole world is encouraging the development and application of new energy to ensure the sustainable development of the future economy. At present, mineral oil is the leading material of transformer insulating oil, accounting for more than 99% of the oil used in the entire transformer industry, which directly leads to the consumption and dependence of oil-immersed transformers on limi...
