The S11 and S13 series of fully sealed oil-immersed transformers from Shandong Zhifeng Transformer Co., Ltd. are designed for use in AC 50Hz power systems with original working voltages of 20kV and below. These transformers are ideal for industries such as petroleum, metallurgy, chemical, textile, light industry, and other enterprises operating in large dust-prone environments. The transformers are highly efficient and reliable, making them suitable for distribution purposes.
Characteristics of the product
Iron Core
The core is cold rolled silicon copper sheet with high permeability magnetic grain orientation. The iron core is a new type of iron core, full oblique joint stacking type iron core, the iron core column is a circular section of multi-step steps, and the iron yoke and the iron core are equal sections.
Winding
The winding adopts corrugated oil channel, no paint dipping process, and tight tape binding; The windings are concentric coils: the high voltage winding has a tap required for the tapping voltage, which is led to the tap-changer, the switch is installed on the box cover, and the power supply can be changed before the tapping voltage.
Safety protection device
30~2000kVA transformer is equipped with pressure relief valve;
Gas relays with alarm and tripping terminals can be installed according to user requirements;
Oil temperature measuring device
The transformer is equipped with a glass thermometer tube base, the tube base is located on the top of the tank, and extends into the oil 120±10mm; 1000~2000KVA transformer equipped with outdoor signal thermometer;
Transformer tank
The transformer oil tank is composed of corrugated walls with dust surface
Spray, paint film firmly. The corrugated heat sink not only has a cooling function, but also has a "breathing" function, and the elasticity of the corrugated heat sink can compensate for the change in the volume of transformer oil caused by the temperature rise and fall. Therefore, the fully sealed transformer has no oil storage tank, reducing the overall height of the transformer;
When the transformer is packaged, the vacuum oiling process is used to completely remove the moisture in the transformer, and the transformer oil does not contact with the air. It can effectively prevent the oxygen and moisture from invading the transformer and lead to the deterioration of the transformer insulation performance and the transformer oil aging, so the oil sample test is carried out from time to time.
