Product Introduction
Solar transformers, particularly step-up transformers, play a key role in grid-connected photovoltaic power generation systems. They are primarily used to boost the low-voltage AC power (0.4kV) output of the inverter to medium- and high-voltage (such as 11kV, 33kV, 110kV, and 220kV) levels, matching the grid voltage. This high-voltage connection enables long-distance transmission of electricity. Selecting the right transformer can significantly improve the overall performance and reliability of a photovoltaic system.
Transformers also play a crucial role in energy storage power plants. Within energy storage power plants, energy storage transformers perform two primary functions: voltage conversion and adaptation; and optimizing power transmission and ensuring grid stability.
Features
- Highly Efficient and Energy-Saving Design
The use of high-permeability silicon steel laminations and a stepped lamination process effectively reduces both no-load and load losses. The optimized electromagnetic design improves operating efficiency and reduces operating costs. - Reliable and Durable Structure
The enhanced short-circuit resistance design, coupled with a comprehensive temperature control and protection system, ensures the transformer maintains reliable and stable performance under different operating conditions. The product has a design life of over 25 years and has passed relevant durability tests.
