Transformers are a vital element of any power distribution system. In order to achieve enhanced operational safety, transformers are normally installed in protective enclosures. Using enclosures with a high protection class, the transformer is optimally protected against adverse environmental conditions, such as dirt, carbon or metal dust, or dampness and moisture, thus increasing the lifetime of the transformer. Thanks to a cooling system newly developed by ABB, there are interestin
This document describes the ABB 1LDE000082, a thermosyphon-based air-to-air cooling system designed for dry-type transformers installed in protective enclosures. The system utilizes passive heat transfer without pumps or control systems to remove heat generated by the transformer.
The datasheet outlines the benefits of this technology, including improved cooling efficiency, reduced power consumption, lower noise emissions (up to 10 dB), and increased reliability through redundancy options. It also provides specific dimensions for different cooling capacities ranging from up to 30 kW to up to 107 kW.
| Cooling Capacity Range | up to 30 kW, up to 50 kW, up to 60 kW, up to 80 kW, up to 107 kW |
|---|---|
| Dimensions (up to 30 kW) | 750 x 1895 x 2226 mm |
| Dimensions (up to 50 kW) | 896 x 1600 x 2550 mm |
| Dimensions (up to 60 kW) | 896 x 1800 x 2700 mm |
| Dimensions (up to 80 kW) | 1892 x 1530 x 2800 mm |
| Dimensions (up to 107 kW) | 1892 x 1530 x 2800 mm |
| Noise Reduction | reduced by up to 10 dB |
It functions in purely passive mode without any pumps or control systems, using a hermetically sealed system where vapor rises and condenses to transfer heat.
It offers improved cooling with reduced power consumption, further energy savings via speed control, less material required, more compact dimensions, and increased reliability.
Yes, it is a closed circuit protected against polluted air, with all components located inside the protective enclosure.
