Product Introduction
The S11 and S13 series of fully-sealed, oil-immersed transformers are meticulously crafted for AC 50Hz systems with primary voltages up to 20kV. These transformers are paragons of reliability, engineered to cater to the diverse needs of industries such as petroleum, metallurgy, chemicals, textiles, and light manufacturing. Their superior performance makes them exceptionally suitable for high-dust environments, ensuring seamless and efficient power distribution.
Product Characteristics
Iron Core
Constructed from high-permeability, cold-rolled silicon copper sheets with magnetic grain orientation, the iron core boasts a groundbreaking oblique-joint, stacked design. The multi-step circular section column with a uniformly sectioned iron yoke and core substantially elevates overall efficiency and performance.
Winding
Our winding system features innovative corrugated oil channels, eliminating the need for conventional paint dipping and utilizing tight tape binding instead. The concentric coil windings facilitate high-voltage tapping, connected to a tap-changer with a conveniently located switch on the box cover for effortless pre-tapping voltage adjustments.
Safety Protection Device
Transformers with ratings between 30 and 2000kVA are outfitted with pressure relief valves to ensure optimal safety.
For enhanced functionality, gas relays with alarm and tripping terminals can be installed as per user requirements, providing comprehensive protection.
Oil Temperature Measuring Device
The transformer incorporates a glass thermometer tube base at the tank's top, extending 120±10mm into the oil. Models ranging from 1000 to 2000kVA are equipped with an outdoor signal thermometer for precise temperature monitoring.
Transformer Tank
The transformer tank features robust corrugated walls, finished with a durable, dust-resistant paint film. The corrugated heat sink not only provides efficient cooling but also adapts to oil volume changes due to temperature fluctuations, eliminating the need for an oil storage cabinet. The vacuum oil filling process ensures comprehensive moisture removal, preventing oxygen and moisture ingress and preserving insulation integrity, thereby reducing oil aging. Regular oil sample tests are advised for optimal performance.
