Thermal behaviour analyses of gas‐insulated switchgear compartment using thermal network method. Issue 12 (1st September 2016) - Stosur, Mariusz
Abstract : In development of electric power products, aspects related to thermal phenomena are becoming very important due to the fact that they guarantee the correct operation of product. The temperature limits specified by the standards cannot be exceeded which makes the knowledge of the temperature behaviour an important factor in order to predict reliability and performance of the product component in its working environment. In this study, thermal network method (TNM) is used for modelling of temperature conditions in typical geographical information system (GIS) compartment arrangements. Models implemented in ATP–EMTP software were validated with OrCAD Capture simulation environment and with high‐current measurement results. On the bases of the TNM presented as the network approach composed of heat sources, thermal resistances and capacitances which can be easily represented and calculated by means of ATP–EMTP simulation software and also with the OrCAD Capture environment. This study addresses the thermal behaviour of a standard ELK‐3 GIS compartment. Modelling in application to design rating calculations of the typical GIS compartment arrangements are presented and analysed. These analyses can serve as a base for development of more advanced ATP–EMTP models using the TNM approach.
