УВЕЛИЧЕНИЕ НАГРУЗОЧНОЙ СПОСОБНОСТИ ЭКСПЛУАТИРУЕМЫХ СИЛОВЫХ ТРАНСФОРМАТОРОВ

Abstract

Increasing the efficiency of high-voltage substations without the need to replace existing power equipment gives a great economic advantage in modern energy. These studies open up new prospects for the energy industry and can bring significant benefits from both economic and environmental points of view. Аim of research Improving the reliability and load capacity of operated power transformers by upgrading the cooling system. Research methods To achieve this aim, it was proposed to use additional temperature control devices by means of upgrading the cooling system and replacing the active part of transformers using modern insulating materials. The possibility of increasing the load capacity of transformers due to the introduction of a new transformer oil cooling system based on an innovative design of cooling radiators is analyzed. A set of monitoring and control devices is also considered, which is considered the most economical and efficient in terms of performance. Results As a result of the conducted research, it was found out that the introduction of a new cooling system for power transformers and the measures taken to replace the insulation of the active part can increase the load capacity by 30–40 %. And the use of additional devices for temperature control allows you to predict possible problems and take measures to prevent or solve them, which significantly increases the reliability of power supply.
