LOAD CONDITIONS AND EVALUATION OF THE RISE OF TEMPERATURE IN AN ENCLOSED CONDUCTOR

František Janíček - Justín Murín - Jaroslav Lelák

   Reliability of drives and electric systems in the auxiliaries of a power plant strongly affects the safety and operation reliability of the power plant blocks as well as the reliability of electric power delivery. The reliability of electric systems is affected - to a large extent - by the reliability of their supplying and by the overall design of the main electric scheme of the power plant. This contribution is concerned with a check computation of the load conditions in special busbars of reserve transformers in nuclear power plants. Additionally, evaluation of the rise of temperature of an enclosed conductor caused by Joule losses has been carried out by analytical and finite element methods.

Keywords: auxiliaries, nuclear power plant, load condition, enclosed conductor, heat transfer, finite element methods
