Epoxy resin cast three-phase dry-type transformer Introduction
The main difference between the delta-star dry-type transformer and other transformers lies in its core structure and performance characteristics.
Core structure
The delta-star dry-type transformer adopts a three-dimensional triangular wound core core component, the three-phase magnetic circuit is completely symmetrical, the magnetic resistance is greatly reduced, and the excitation current and no-load loss are significantly reduced.
This structure makes the transformer more stable during operation and has better noise control.
Performance characteristics Material saving: Due to the three-dimensional triangular structure, the delta-star dry-type transformer can save materials compared with traditional stacked core transformers.
Low noise: As the running time increases, the wound core is more stable and the noise will not change.
High efficiency and energy saving: The three-phase magnetic circuit is completely symmetrical, the excitation current and The no-load loss is significantly reduced, which improves the efficiency of the transformer.
Noise control: The clamps of the steel structure effectively suppress the oscillation of noise in the clamps, so that the noise of the transformer remains in an ideal state.

Application scenarios and maintenance costs of delta-star dry-type transformers.
Delta-star dry-type transformers are suitable for occasions that require low noise and high stability, such as places that require fire and explosion protection, high-rise buildings, commercial centers, etc.
Although its cost is high and its volume is large, it is still widely used in the field of high-power power transmission due to its high efficiency, energy saving and low noise.
High-rise buildings: Provide a stable power supply. Commercial center: Ensure the power demand of commercial activities. Airports, tunnels, chemical plants, nuclear power plants, ships: Excellent performance in special or harsh environments
