定义
Cooling radiators/tubes are essential thermal management components in power transformers, consisting of interconnected finned tubes or radiator panels that facilitate heat transfer from the transformer's insulating oil to the surrounding air through natural or forced convection. They are designed to maintain dielectric fluid temperatures within safe operational limits, preventing thermal degradation of insulation materials and ensuring transformer efficiency and longevity.
工作原理
Heat from the transformer core and windings transfers to insulating oil, which circulates through the radiator tubes. The extended surface area of fins increases heat dissipation to ambient air via convection, with temperature differentials driving natural oil flow or assisted by pumps in forced cooling systems.
材料
Carbon steel (ASTM A36/A283)stainless steel (AISI 304/316)aluminum alloys (6061/6063)with corrosion-resistant coatings (epoxygalvanization) and welded/brazed joints.
Surface Area
5-50 m² per radiator
Oil Flow Rate
10-100 L/min
Temperature Range
-40°C to 120°C
Operating Pressure
0.5-2.0 bar
Heat Dissipation Capacity
50-500 kW per radiator bank
标准
ISO 9001IEC 60076IEEE C57.12.00DIN 42500

常见问题

What is the difference between natural and forced cooling in transformer radiators?

Natural cooling relies on thermal convection for oil circulation, while forced cooling uses pumps/fans to enhance heat dissipation, allowing higher load capacity.

How often should transformer radiators be inspected?

Visual inspections every 6 months, with thermal imaging and leak testing annually, following IEEE C57.12.00 maintenance guidelines.
