1. Selection Precautions
Packaging and transportation: the product packaging should be intact, printing font clear and beautiful, complete and correct signs (such as factory name, trademark, etc.). Care should be taken to avoid collision and vibration during transportation to ensure that the product is not damaged.
Safety performance: ensure that the selected transformer meets the national safety standards and industry standards, with perfect safety protection measures.
Environmental requirements: focus on the environmental performance of the transformer, select the environmental requirements of low noise, low emission products.
2. Transformer Applications in Renewable Energy
WTGs: In the process of generating electricity from wind turbine generators (WTGs), the rotation of the wind turbine drives the generator to produce electricity, typically in the form of low voltage alternating current (AC). The transformer plays a crucial role by stepping up this low-voltage power to a higher voltage (e.g., 35kV or higher) for transmission via lines to the grid, located away from the power farm.
Integrated systems: Within large wind farms, multiple WTGs are often linked to a substation where a transformer aggregates and steps up the total power generated by all units, facilitating efficient power delivery. Additionally, the transformer manages voltage and frequency discrepancies among different WTGs, ensuring stable system operation.
