I. Robust Structure and Cutting - Edge Design
Tank
- Constructed from extremely thick, super - high - strength alloy steel plates, the tank of this 1600kV transformer offers unrivaled mechanical integrity. Its airtight sealing is achieved through advanced gasket and welding techniques, providing an impermeable barrier against wind - borne debris, torrential rain, and moisture. This not only safeguards the internal components but also ensures long - term reliability in the harshest outdoor environments.
- The tank surface undergoes a multi - layer anti - corrosion treatment, including the application of specialized high - performance coatings. These coatings are designed to resist corrosion from a variety of chemical substances and environmental factors, extending the transformer's service life to several decades.
Core
- Composed of ultra - high - grade, extremely high - permeability silicon steel sheets, the core is optimized to minimize both hysteresis and eddy - current losses to an absolute minimum. This results in an astonishingly high level of energy efficiency, reducing power consumption and operational costs significantly.
- The core features a unique, patented fully - inclined joint structure that not only minimizes vibration but also virtually eliminates noise emissions. This makes the transformer suitable for installations near residential areas or noise - sensitive facilities, despite its high - voltage operation.
Windings
- Wound with the purest, highest - conductivity copper conductors of massive cross - sectional area, the windings are engineered to handle the extremely high - voltage and high - current demands of a 1600kV system. The copper wires offer exceptional electrical conductivity and mechanical strength, ensuring reliable and efficient power transfer over long distances.
- The winding design is highly customized to meet the precise voltage transformation ratios and capacity requirements of different power distribution applications. State - of - the - art insulating materials, such as high - temperature - resistant, moisture - proof, and corona - resistant polymers, are used to provide unparalleled electrical insulation and efficient heat dissipation.
II. Exceptional Performance Attributes
High - Efficiency and Energy Conservation
- Through a combination of revolutionary design concepts and the use of top - tier materials, this 1600kV transformer achieves near - theoretical maximum efficiency levels. It far surpasses industry - standard efficiency ratings, leading to substantial energy savings and a significant reduction in carbon footprint for power grid operators.
Robust Overload Capability
- Equipped with advanced thermal management and power - handling systems, the transformer can safely and effectively handle substantial short - term overloads. This enables it to meet sudden and extreme spikes in power demand, ensuring uninterrupted power supply to critical industrial, commercial, and utility customers.
Superior Heat Dissipation
- The oil - immersed design, in conjunction with a massive and highly efficient cooling system, ensures rapid and effective heat transfer from the core and windings to the tank surface. Gigantic heat - dissipation fins, with an optimized surface area and shape, are attached to the tank. These fins, along with natural air circulation or optional forced - air cooling systems, enhance heat dissipation efficiency, maintaining the transformer's operating temperature within the optimal range even under full - load and extreme - temperature conditions.
Stable and Reliable Operation
- The transformer undergoes the most stringent factory testing procedures, including ultra - high - voltage withstand tests, partial discharge tests, and thermal stability tests. Additionally, it can be integrated with real - time monitoring and diagnostic systems that use advanced sensors and analytics to continuously assess its performance. This comprehensive quality control approach ensures stable and reliable operation under a wide range of environmental and electrical conditions.
III. Comprehensive Technical Specifications
Rated Capacity
- Available in capacities ranging from 300MVA to 1000MVA or even higher for specialized applications, to meet the diverse and growing power requirements of large - scale power distribution systems.
Rated Voltage
- High - Voltage Side: 1600kV
- Low - Voltage Side: Customizable, with common options including 220kV, 500kV, depending on the specific power grid configuration and end - user requirements.
Frequency
- Standard frequency of 50Hz or 60Hz, with the flexibility to be customized according to regional power grid requirements.
Cooling Method
- Primarily uses the ONAN (Oil Natural Air Natural) cooling method for normal operating conditions. For high - load or extreme - temperature applications, an optional ONAF (Oil Natural Air Forced) or even more advanced cooling systems, such as ODWF (Oil Directed Water Forced), can be installed to enhance cooling performance.
Insulation Level
- High - voltage: LI 2800 AC 1700 kV
- Low - voltage: Insulation levels are precisely adjusted according to the specific low - voltage rating, with appropriate lightning impulse (LI) and power frequency withstand (AC) values.
Temperature Rise
- Under full - load conditions, the winding temperature rise is strictly controlled to within 70°C, while the oil temperature rise is limited to 60°C. This ensures the long - term integrity of the insulation materials and the reliable operation of the transformer.
Efficiency
- Achieves an outstanding efficiency of over 99.5% under typical load conditions, highlighting its remarkable energy - saving capabilities and contribution to sustainable power distribution.
Standards Compliance
- Strictly adheres to international standards such as IEC 60076 series, IEEE C57 standards, and other relevant national and international regulations, ensuring the highest quality and safety levels.
IV. Diverse Applications
Ultra - High - Voltage Transmission Grids
- Forms the backbone of ultra - high - voltage (UHV) transmission networks, enabling the efficient transfer of large amounts of electricity over extremely long distances, from power generation sources such as large - scale hydroelectric, nuclear, or coal - fired power plants to major load centers.
Large - Scale Industrial Complexes
- Ideal for powering colossal industrial complexes, such as integrated steel plants, large - scale petrochemical refineries, and advanced semiconductor manufacturing facilities, where a stable and high - capacity power supply is crucial for continuous operation.
Renewable Energy Integration
- Plays a pivotal role in integrating large - scale renewable energy sources, such as vast wind farms located in remote areas or extensive solar power plants in deserts, into the main power grid. It helps in stepping up the voltage of the generated electricity for efficient transmission over long distances to population centers.
