In my country, epoxy resin vacuum casting Dry-type transformer dominates the market. In addition, from the main distribution transformers to power plant excitation transformers, plant transformers, rail transit traction rectifier transformers, high-current electric furnace transformers, nuclear power plants, marine, oil production platforms, and other special transformers and multi-purpose multi-field development. In recent years, Zhejiang Shuntong Electric Co., Ltd. has developed and mass-produced these special products in many fields.
READ MOREOil-filled transformers use oil as the main insulation means of the transformer and rely on oil as the cooling medium, such as oil-immersed natural cooling, oil-immersed air cooling, oil-immersed water cooling, and forced oil circulation. Oil-filled transformers can operate as specified on the nameplate under the specified cooling conditions, but the top oil temperature should not exceed 90℃. To prevent the insulation of oil-filled transformers from aging, the top oil temperature should not exceed 85℃ frequently, and the alarm setting should be set at 80°C. The following is an introduction to the performance characteristics of oil-filled transformers.
READ MOREIn life, an Air-cooled Transformer is often used. Air-cooled Transformers are the main transformers in power systems with a capacity of 60MVA and above. Next, let's take a look at the introduction and performance characteristics of the Air-cooled Transformer.
READ MOREOil sealed transformers can be used indoors and outdoors and can be installed on poles when the capacity is 315kVA and below. The ambient temperature is not higher than 40℃, not lower than -25℃, the highest daily average temperature is 30℃, the highest annual average temperature is 20℃, the relative humidity does not exceed 90%, and the altitude does not exceed 1000m.
