High voltage oil transformer is one of the main equipment in power plant and substation. The function of transformer is multifaceted, which can not only raise the voltage to send the electric energy to the area where electricity is used, but also reduce the voltage to all levels of using voltage, so as to meet the needs of electricity consumption. In a word, the boost and drop must be done by the transformer.
In the process of transmitting electric energy in a power system, voltage and power losses are inevitably generated. When the same power is transmitted, voltage losses and voltage are inversely proportional, and power losses and the square of voltage are inversely proportional. Transformer is used to increase voltage and reduce transmission loss.
1. Installation type: Outdoor;
2. Normal environmental conditions: altitude does not exceed 1000m, the highest ambient temperature +40℃, the lowest temperature -25℃;
3. Installation environment: no corrosive gas, no obvious dirt environment.
● In the power transmission and distribution system of 10KV and 50HZ, it can be widely used in high-rise buildings, commercial centers, subways, airports, stations, industrial and mining enterprises, drilling platforms, oil production platforms, especially suitable for places with high fire requirements and harsh environment such as inflammable and explosive. It can also be used in residential areas, commercial streets, industrial and mining enterprises and rural power and lighting.
● Long service life, maintenance-free operation. Fully sealed transformer box cover and box edge adopt bolt connection or welding structure, insulate oil and air contact, insulation will not be affected by moisture, greatly reduce the aging speed of insulation, improve the service life.
● The design structure is compact and the running noise is low. Due to the use of new materials and new technology, reduce noise, no oil storage tank, the height is lower than similar products. During the normal life, no oil change is needed, which improves the safety and reliability of the operation in the network.
● Corrugated fuel tank small size, beautiful appearance. The S11 type power transformer oil tank adopts corrugated plate type heat dissipation. When the oil temperature changes, the change of oil volume is adjusted and compensated by the elastic expansion and contraction of corrugated plate.
● No core and oil inspection. During transformer packaging, vacuum filter oil filling process is adopted to completely remove moisture in transformer oil. After sealing, there is no contact with air inside the transformer, which can effectively prevent oxygen and moisture from entering the transformer and causing the insulation performance decline.
