AI Technical Summary
Existing dry-type transformers cannot effectively reduce noise during use, leading to environmental pollution.
The system employs cooling and noise reduction components, including a lifting shell, support block, shock absorber, fan, ventilation slot, dust baffle, and corrugated sound-absorbing sponge. Combined with the lifting components and temperature sensor, it achieves noise absorption and heat dissipation.
It effectively reduces noise pollution, improves heat dissipation efficiency, enhances equipment safety, and facilitates maintenance.
