Yyn0 6.6kv Low Voltage Efficient Durable Oil-Immersed Transformer
Structural composition
Core: Generally, high-magnetic-conductivity high-quality cold-rolled grain-oriented silicon steel sheets are used. Through a Jorg line automatic stacking robot, they are stacked together. This can significantly reduce no-load loss, no-load current, and noise. At the same time, the surface is coated with resin paint, which serves to prevent moisture and rust and reduce noise.
Winding: The high-voltage winding and low-voltage winding usually use high-quality enameled copper wire or copper foil. When using high-density point-paste paper as interlayer insulation when using high-density enameled copper wire, it can effectively improve the anti-short-circuit ability; when using copper foil, it is wound by an automatic foil winding machine and internally welded under nitrogen protection. The welding quality is high, the resistance is small, and the interlayer insulation uses F-grade pre-impregnated fabric to improve electrical and structural strength.
Transformer oil: As a cooling and insulation medium, it can effectively prevent short circuits between the winding and the core, and can also remove the heat generated inside the transformer through circulation flow, maintaining the equipment within an appropriate working temperature range.
Oil reservoir: It serves to store or replenish oil, ensuring that the oil tank is filled with oil, while reducing the contact area between the oil and air, slowing down the deterioration rate of the oil. It is equipped with an oil level gauge on the side to monitor the changes in the oil level.
Performance characteristics
High efficiency and energy saving: With advanced design and high-quality materials, the transformer's no-load loss and load loss are both low, effectively saving energy and reducing operating costs.
Durable and reliable: It has strong overload capacity and anti-sudden short-circuit performance, and can operate stably in harsh working environments for a long time. At the same time, through strict quality control and testing, the reliability and service life of the transformer are ensured.
Good insulation performance: The good combination of transformer oil and insulation materials, as well as the reasonable insulation structure design, enable the transformer to have high insulation strength, effectively preventing short circuits and leakage faults.
Excellent heat dissipation performance: The circulation flow of transformer oil can quickly remove heat, and through heat exchange with external air through a heat exchanger, the transformer can maintain a low temperature even under high-load operation, ensuring stable performance. Working principle
Electromagnetic Induction: When an alternating current passes through the primary winding (high-voltage winding) of a transformer, the changing magnetic field generated by the current will act on the secondary winding (low-voltage winding) through the iron core, thereby inducing changes in the current in the secondary winding. According to the law of electromagnetic induction, voltage transformation is achieved.
Voltage Transformation: Voltage change is directly proportional to the ratio of the number of turns of the windings. Since the number of turns in the high-voltage winding is greater than that in the low-voltage winding, the 6.6 kilovolt high voltage is transformed into a voltage suitable for low-voltage electrical equipment for use in commercial buildings such as shopping malls, office buildings, and hotels.
Application Areas
Industrial Field: To provide stable power supply for various production equipment in factories, such as electric motors, machine tools, cranes, etc., ensuring the normal operation of industrial production.
Commercial Field: For the power distribution systems of commercial buildings such as shopping malls, office buildings, and hotels, providing power for lighting, air conditioning, elevators, etc.
Residential Areas: As a distribution transformer for residential areas or houses, it reduces the high-voltage power and distributes it to each user's home to meet the daily electricity needs of residents.
