AI Technical Summary
The insulation materials of existing dry-type transformers have low thermal conductivity, which causes heat to accumulate in the core heat-generating parts, affecting the insulation performance and operational stability of the transformer.
It adopts composite insulating phase change heat dissipation material, and uses functional plates made of paraffin-based phase change energy storage components and high thermal conductivity fillers such as graphene and alumina. Combined with heat dissipation fins and cleaning mechanism, it realizes the absorption, storage and rapid dissipation of heat.
It improves the heat dissipation of dry-type transformers, reduces temperature rise, enhances insulation performance and operational stability, and extends service life.
