2000 kVA 10 kV Low-Loss Oil Immersed Transformer: High-Efficiency Mainstream Power Distribution Equipment
The industry commonly suffers from the pain points of high losses and persistently high electricity costs associated with traditional power distribution transformers. Purchasers often encounter problems such as severe equipment overheating, poor compatibility with supporting equipment sets, and high long-term maintenance costs. This 2000 kVA 10 kV low-loss Oil-immersed Transformer features a specifically optimized core and winding structure, balancing heat dissipation efficiency and Energy Efficiency indicators, and is compatible with various power distribution equipment sets. After being put into operation, it can significantly reduce no-load and load losses, reduce long-term electricity expenses, and stably support the continuous power supply needs of factories, photovoltaic power plants, and municipal power grids. This device can be paired with a High And Low Voltage Switchgear to form a complete power distribution circuit, suitable for box-type substation outdoor installation solutions. In new energy projects, it can be used with an Electric Power Converter to complete power voltage regulation and conversion, distinguishing it from the Dry Type Transformer used in indoor confined scenarios. It can also serve as the core boost unit within Combined Photovoltaic Substations, widely used in large-scale factory power distribution, urban community power grid upgrades, distributed photovoltaic grid connection, and centralized power supply for commercial complexes. With stable voltage output, it reduces harmonic damage to downstream equipment, lowers the overall power supply system failure frequency, and is suitable for various installation environments such as outdoor open-air locations and factory substations, balancing long-term economic efficiency and operational safety.
ميزات المنتج
Ultra-Low Loss Core Technology:Utilizing high-permeability silicon steel sheets cut and stacked, the no-load loss is far lower than industry standards, resulting in lower energy consumption during long-term continuous operation, suitable for projects requiring uninterrupted power supply year-round.
Fully Sealed Leak-Proof Oil Tank Structure:The corrugated oil tank automatically compensates for volume expansion and contraction due to oil temperature changes, reducing the risk of oil leakage and eliminating the need for frequent oil repairs in outdoor conditions.
نصائح الاستخدام
When installing the equipment, ensure adequate ventilation and heat dissipation space. Maintain a safe and standardized distance from surrounding high and low voltage switchgear to prevent heat buildup and accelerated insulation aging.
Before restarting after a long-term shutdown, test the insulating oil withstand voltage. Filter and replace the oil promptly if it deteriorates to ensure stable internal winding insulation performance.
الأسئلة الشائعة
Q: Can this Oil Immersed Transformer be directly installed in a Box Type Substation?
A: Yes, the equipment’s dimensions are compatible with standard box-type substation enclosures. It comes with pre-installed standard high and low voltage terminals for quick assembly with internal switch components of the complete box-type substation.
Q: Compared to a Dry Type Transformer, why is this model preferred for outdoor projects?
A: Oil immersion provides superior heat dissipation, resulting in lower purchase and maintenance costs for the same capacity. It is resistant to sun and rain, requires only periodic oil quality testing, and is suitable for open-air substations without a sealed indoor distribution room.
Q: Is the equipment compatible with the Combined Photovoltaic Substation grid connection process?
A: Fully compatible. It can be used with an Electric Power Converter to boost low-voltage photovoltaic power to the standard 10 kV grid voltage. It includes a built-in tap changer to adapt to photovoltaic output fluctuations.
Q: What is the routine maintenance cycle, and what tests are required?
A: Check the oil level and seals for oil leaks every six months. Have the insulating oil withstand voltage tested annually. Tighten the high and low voltage copper busbars. Frequent disassembly of the internal components is unnecessary.
Q: What components are covered by the after-sales warranty? How long is the warranty period?
A: The core, windings, and main tank are covered by a three-year warranty. Accessories such as gas relays and pressure relief valves are covered by a one-year warranty. Remote technical guidance and on-site troubleshooting services are provided.
