Message: | Wuhan HuaChen DingFeng Electricity Company was founded in 10 years ago, After a period of rapid development, it has developed into a considerable size and effectiveness company of three-phase double-windingx1b41dcanand35 kv oil-immersed, NOw it is benchmark companies in Industry and agriculture industry. ding fengOil-immersed power transformer
Oil-immersed power transformer, distribution transformer for industrial and mining enterprises and civil building one of the important equipment in power supply and distribution system, it will be 10 kv series double winding oil-immersed power transformers, 20 kv double winding oil-immersed transformer or 35 kv oil-immersed power transformer network voltage drop to the user use 230/400 v bus voltage. Such products applied to ac 50 Hz (60), maximum rated capacity of 2500 kva three-phase (single phase maximum rated capacity of 833 kva, single-phase transformer is generally not recommended), can be used in indoor (outside), when capacity of 315 kva and below can be installed on the pole, environment temperature is not higher than 40 ℃, no less than 25 ℃, the highest daily average temperature 30 ℃, the highest annual average temperature is 20 ℃, relative humidity less than 90% (environment temperature 25 ℃), the altitude does not exceed 1000 m.
A 1000kVA and above oil-immersed transformer shall be equipped with an outdoor signal thermometer and can take distant signals. 800kVA and above oil-immersed transformer shall be equipped with gas relay and pressure protection device. The oil immersed transformer below 800kVA shall be negotiated with the manufacturer according to the requirements, and may also be equipped with a gas relay. Dry type transformers shall be installed in accordance with the manufacturer's requirements, and shall be equipped with temperature measuring devices, generally 630kVA and abov |
