Modernizace rozvodny 6 kV v Teplárně Trmice a.s.

Abstract

The theme of the thesis is based on the practical requirements from the department of Electronics and Instrumentation in the Trmice Heating plant. There is described the current state of the switchboard R6kV-K6 focusing on used electrical devices and their maintenance, on level of safety during operation and maintenance and overall reliability. The next chapter summarizes current trends in production of high voltage devices and in modernization of old ones, which no longer meet current demands on safety and reliability of operation, or they are already on the threshold of life time and cost of maintance is therefore too high. All these findings are at the end of the chapter also applied to the specific case of switchboard R6kV-K6 resulting in reasons why to invest into modernization. The last chapter then presents practical alternative solutions with subsequent evaluation. This thesis could also help as a basis for future entry documentation.
