Description
Currently, in the field of high-voltage power distribution, there are industry pain points such as low Energy Efficiency of large-capacity equipment and insufficient stability for outdoor operation. Buyers often face issues related to the equipment’s compatibility and excessively high post-purchase operation and maintenance costs. We have launched the 220 kV 12500 kVA Oil-immersed Power Transformer, which can be used in conjunction with Box Type Substation and High And Low Voltage Switchgear to meet the high-load requirements of high-voltage power distribution. In practical applications, it can significantly reduce energy consumption and minimize downtime due to failures, balancing practicality and economy. Its core value lies in achieving efficient conversion and stable transmission of high-voltage electrical energy. It is widely used in high-load new energy grid connection, large industrial clusters, and regional backbone power grids, connecting with Electric Power Converter and Combined Photovoltaic Substations, and filling the gap in compatibility for large-capacity high-voltage power distribution.
Compared to Dry Type Transformer, this transformer is more suitable for outdoor high-load complex environments. With excellent insulation and heat dissipation performance, it can operate stably for a long time in various high-load scenarios, playing a key role in voltage regulation and load distribution, providing reliable power support for high-load production and living, and new energy centralized grid connection. At the same time, it complies with the new national energy efficiency standards, and long-term operation can significantly reduce electricity costs.
I. Product Features
1. Capable of handling high loads with excellent energy efficiency, it can be seamlessly integrated with Box Type Substation and High And Low Voltage Switchgear. It can be flexibly adjusted according to the demands of different high-load scenarios such as Combined Photovoltaic Substations and large industrial clusters. The no-load loss is more than 8% lower than the national standard’s first-level energy efficiency limit, making it more energy-efficient during long-term high-load operation.
2. It has outstanding outdoor high-load tolerance performance. It adopts a fully sealed oil tank design, which can withstand outdoor temperature and humidity changes, as well as dust erosion. Compared with Dry Type Transformer, it does not require special indoor protection. It is suitable for outdoor high-load high-voltage power distribution scenarios, and has a fault rate much lower than the industry average, enabling continuous and stable operation.
II.Tips
During installation, it is necessary to maintain the prescribed spacing from the Electric Power Converter and High and Low Voltage Switchgear to ensure a secure connection of the lines and prevent any reduction in the efficiency of the equipment during high-load operation due to improper line matching.
2. Daily maintenance is not required frequently. The focus should be on the insulation oil level and oil temperature. During high-load operation, the oil quality inspection cycle can be appropriately shortened to once every 3-4 months, which can effectively extend the equipment’s service life to over 20 years.
III. FAQ (Frequently Asked Questions)
1. Compared to Dry Type Transformer, what are the differences in application scenarios of this transformer? Answer: The main differences between the two lie in the installation environment and load-bearing capacity. The Dry Type Transformer is more suitable for indoor, medium-low load, and densely populated areas. This 220 kV 12500 kVA Oil-immersed Power Transformer is mainly designed for outdoor high-load scenarios, with stronger weather resistance and load-bearing capacity, making it more suitable for large-scale industrial, centralized new energy grid connection, and other outdoor high-load high-voltage power distribution needs.
2. Is the post-maintenance process difficult? Does it require professional operation? Answer: The maintenance process is not difficult. Daily maintenance only requires checking the oil level, oil temperature and appearance. No professional operation is needed. In case of a malfunction, we offer on-site after-sales service within 72 hours. We can also cooperate with Box Type Substation and High And Low Voltage Switchgear for maintenance and debugging to ensure rapid power restoration in high-load scenarios.
3. Can it meet the high-load grid connection requirements of Combined Photovoltaic Substations? Answer: It is fully compatible. It can be combined with the Electric Power Converter to achieve the voltage boost conversion of new energy power, meeting the 220 kV grid connection standards. It can handle the high-load grid connection requirements of centralized photovoltaic and wind power bases, and has been stably put into operation in multiple large-scale new energy projects.
