Wind Turbine Nacelle Dry-Type Transformer
The nacelle dry-type transformer is an important component of the wind power generation system, used to step up the electrical energy generated by the wind turbine to the voltage level of the transmission grid. The nacelle dry-type transformer offers advantages such as small size, light weight, and low maintenance cost. It is capable of adapting to the special environment of the high-altitude nacelle, including low-frequency vibration, high humidity, contamination, and susceptibility to lightning surges. The nacelle dry-type transformer saves high-current low-voltage cables, reduces line losses, saves ground land resources, and shortens the construction period.
Reinforced structural component strength with additional swing arm fixed to the nacelle wall. Finite element analysis (FEA) for steady-state simulation provides strong low-frequency vibration resistance.
CFD (Computational Fluid Dynamics) simulation is used to analyze air flow trajectories and configure fan air guide slots, achieving precision cooling. The product features low temperature rise and long service life.
Protective rings are added to the high-voltage tapping points, significantly increasing creepage distance and adapting to high-humidity environments.
Integrated 400V tapping enables internal 400V power supply.
Surge arresters integrated on the high-voltage side provide protection against lightning surge risks.
The transformer is installed inside the wind turbine nacelle, saving land resources.
Step-up transformation in the high-altitude nacelle saves cable costs.
