Využití termovize při diagnostice prvků distribuční sítě.

Abstract

This dissertation deals with the use of thermography in distribution power networks, it is showed practical use in the operation state. It also includes possible outcomes of individual measurements and tries to solve the issue, what with the measured data after measuring. It focuses on the complications of using thermography in normal operation. It deals with the issue of camera settings, where in practice use is sometimes very difficult to determine the value of adjusted parameters. It shows the emissivity as a very important parameter for measuring and practically dealing with this parameter for some of the most of used metals. It shows the results of regular measurements of individual parts and units of distribution networks, where the results are stored in the database. Further processing of this database shows the measured data and their subsequent analysis articulated in the individual power units. It shows the real data, which was measured at the distribution units and the results of their analysis. These results lead to further problems and this is the problem with pistol deadend clamps. This issue is discussed with specialist and next it is solved by simulation with using the finite element method. As an example for simulations are taken two versions of dead-end clamps and on these clamps are made simulations in software ANSYS Workbench. The results are assessed individually or comparative, depending on the character of the simulation. These simulations are performed to identify the most factors, which have effect on the operation statue of these clamps.
