Oil immersed On-load Transformer

110Kv Oil-immersed On-load Transformer

You can see the figure below in some substations and outdoor telephone poles. Yes, it is an oil-immersed transformer. The oil-immersed transformer is one of the important equipment in the Power Supply and distribution system of industrial and mining enterprises and civil buildings. It reduces the network voltage of 10 (6) kV or 35 kV to the bus voltage of 230/400V used by users. This type of product is suitable for AC 50 (60) Hz, three-phase maximum rated capacity of 2500kVA (single-phase maximum rated capacity of 833kVA, single-phase transformers are generally not recommended), can be used indoors (outside), capacity is 315kVA and below Can be installed on the pole, the ambient temperature is not higher than 40 ℃, not lower than -25 ℃, the maximum daily average temperature is 30 ℃, the maximum annual average temperature is 20 ℃, the relative humidity is not more than 90% (ambient temperature 25 ℃), altitude No more than 1000m. If it is not in conformity with the above conditions of use, appropriate quota adjustments should be made in accordance with the relevant regulations of GB6450-86.

FEATURE

Advantage

1. The transformer oil has good insulation performance and good thermal conductivity, and the transformer oil is cheap.
2. It can solve the problem of large-capacity heat dissipation of transformers and high-voltage insulation.

Disadvantage

1. Transformer oil is flammable, it may burn and explode when it encounters flame
2. Transformer oil is harmful to human body
3. Transformer oil needs regular inspection
4. The oil-immersed transformer has poor sealing performance and should be aged. The leakage of oil in the operating place is serious, which affects the safe operation of the equipment and affects the environment.
5. The oil-immersed transformer has a low insulation level and is designed and manufactured according to A-level insulation
