Product Desctription
S11/S13 series oil immersed distribution transformers use insulating oil as cooling and insulating medium. The core is made of high quality cold rolled sillcon steel, the oil tank adopts corrugated oil tank without oil conservaor. Vacuum oil injection process is adopted to effectively prevent oxygen and water from penetrating into transformer oilresulting in the decline of insulating oil performance. It is a new generation of energy-saving and environmental protection products.
Transformer Adavantage
1 - Low loss, low noise, low partial discharge, low temperature rise and energy-saving
2 - Adopt the latest insulatoin structure
3 - Excellent anti-short-circuit ability.
4 - As to the heat dissipating element adopts corrugated sheet or sheet radiator and other components.
5 - The iron core adopts high quality cold rolled graind oriented silicon steel sheet ,it is low loss and small magnetostriction.The whole iron core adopts the structure of 45-degree full oblique joint and round cross-section, which will not be loosened due to vibration during transportation and operation.
Basic Structure
The oil-immersed transformer mainly consists of core, windings, oil tank, insulation bushings, radiators and other components. The core is usually made of laminated silicon steel sheets to reduce eddy current losses. The windings are wound with copper or aluminum wires and achieve voltage transformation through the principle of electromagnetic induction. The oil tank is used to hold the transformer oil, which plays the roles of insulation, cooling and heat dissipation.
Working Principle
It is based on the law of electromagnetic induction, and changes the magnitude of AC voltage through the turns ratio of the primary winding and the secondary winding. When the primary winding is connected to an AC power source, an alternating magnetic flux is generated in the core, thereby inducing a corresponding voltage in the secondary winding.
