Product Description of Oil Immersed Transformer

Oil-immersed Distribution transformer usually consist of cores, windings, oil tanks, coolers, etc. The cores and windings are immersed in the oil tank containing transformer oil, forming a fully enclosed structure immersed in oil. The corrugated oil tank shell relies on its own flexibility to adapt to the expansion of the oil and achieve permanent sealing.

Oil-immersed transformers use oil as the main insulating medium of the transformer and rely on oil as the cooling medium, such as self-cooling oil-immersed transformers, air-cooling oil-immersed transformers, water-cooling oil-immersed transformers, forced oil circulation oil-immersed transformers, etc. The main parts of the transformer are cores, windings, oil tanks, oil pads, breathing devices, explosion-proof pipes (pressure relief valves), radiators, insulating sleeves, tap switches, gas relays, thermometers, oil purifiers, etc.

Terms and restrictions for use

Environmental Conditions: Oil-immersed distribution transformers are suitable for alternating current of 50 (60) hertz, with a maximum three-phase rated power of 2,500 kilovolt-amperes (maximum single-phase rated power of 833 kilovolt-amperes; single-phase transformers are generally not recommended). They can be used in indoor (outdoor) locations and can be pole-mounted when the capacity is 315 kilovolt-amperes or less. The ambient temperature for use is limited to a certain range, usually not exceeding 40 degrees Celsius and not falling below -25 degrees Celsius, with the highest average daily temperature not exceeding 30 degrees Celsius and the highest average annual temperature not exceeding 20 degrees Celsius. The relative humidity does not exceed 90% (at an ambient temperature of 25 degrees Celsius), and the altitude does not exceed 1,000 meters.
Safety: Since the insulating oil is somewhat flammable, the risk of fire in oil-immersed distribution transformers is relatively high. Therefore, special attention should be paid to fire prevention measures when using them, and regular safety inspections should be carried out.
