AI Technical Summary

Technical Problem

Existing power transformer cooling devices are not efficient enough under high load operation, making it difficult to quickly and effectively reduce the temperature, which affects the stability and lifespan of the equipment.

Method used

The system employs a high-efficiency cooling system consisting of a cold liquid tank, cooling pipes, waterproof cooling plates, air-cooled fan blades, and a rotating motor. Combining liquid cooling and air cooling methods, the system directly cools the iron core and windings with coolant, while the fan blades accelerate airflow. The system also incorporates a water storage tank and a vibrator to prevent media sedimentation and ensure uniform cooling.

Benefits of technology

This achieves efficient cooling of the transformer, ensuring stable operation of the equipment, extending its service life, and preventing data cables from getting damp and leaking.
