High-Efficiency Energy-Saving Oil-Immersed Transformers
A high-efficiency energy-saving oil-immersed transformer is a type of transformer that uses oil as an insulating medium and features an efficient cooling system. Here is a detailed introduction to it:
I. Basic Structure
A high-efficiency energy-saving oil-immersed transformer mainly consists of a core, windings, an oil tank, a cooler, and other components:
- Core: The core component of the transformer, composed of multiple silicon steel sheets, which can effectively reduce iron loss and eddy current loss.
- Windings: Conductor coils located on the core, which realize the conversion of electrical energy through magnetic induction.
- Oil Tank: A container for storing transformer insulating oil, which isolates and cools the windings.
- Cooler: A device that helps with heat dissipation, typically using fans or water cooling methods.
II. Working Principle
The working principle of a high-efficiency energy-saving oil-immersed transformer is based on electromagnetic induction. When an AC current passes through the high-voltage winding, it generates a strong magnetic field in the core. This magnetic field can penetrate the windings and induce an AC voltage in the low-voltage winding.
III. Main Features
- High Efficiency and Energy Saving: The advanced cooling system reduces temperature to an appropriate level, minimizing energy waste, improving transformer efficiency, and lowering energy consumption.
- Environmentally Friendly and Safe: Uses environmentally friendly oil as the insulating medium, which has excellent insulating properties and pollution resistance. Additionally, various protective measures ensure the safe and reliable operation of the equipment.
- Convenient Maintenance: Relatively simple structure and easy maintenance effectively extend the service life of the equipment.
IV. Application Advantages
- Strong Adaptability: Can adapt to different working environments and load conditions, providing reliable protection functions to ensure the safe operation of the system.
- Wide Range of Applications: Can be widely used in power systems, industrial and mining enterprises, urban construction, and other fields, improving the power supply quality and stability of the power grid while saving energy.
V. Specific Model and Features (Taking S13-1600KVA as an Example)
- Low Loss: Uses new core materials and optimized processes, resulting in low losses on both the low-voltage and high-voltage sides.
- Low Noise: Incorporates multiple technological improvements to reduce noise levels below national standards.
- Sturdy Structure: The low-voltage winding uses copper wire winding structure, while the high-voltage winding adopts a multi-layer winding structure. It has high mechanical strength and strong short-circuit resistance. The core and windings have their own reinforcement measures, and the solid parts of the transformer body, such as the high and low-voltage leads, are equipped with self-locking and anti-loosening nuts. It adopts a non-lifting core structure, which can withstand the vibration during transportation.
- Advanced Technology: The coil and core are vacuum-dried, and the transformer oil undergoes vacuum filtration and oil filling processes to minimize internal moisture. The oil tank uses corrugated sheets with breathing function to compensate for oil changes caused by temperature variations. Additionally, the corrugated sheets replace the oil conservator, isolating the transformer oil from the outside world and effectively preventing the ingress of oxygen and moisture, which would degrade insulation performance.
- Complete Protective Devices: When the transformer fails and causes internal pressure to reach 35Kpa, the pressure relief valve actuates to release pressure or alarm. When the pressure decreases to normal, it returns to its original state, allowing the transformer to continue operating. Transformers with a capacity of 800KVA and above are equipped with signal thermometers and gas relays, which trip or alarm at appropriate temperatures.
