Srovnání parametrů vakuových vypínačů a stykačů do 17,5 kV.

Abstract

The purpose of this thesis is to explain the function and comparing the parameters of vacuum switchgear (circuit breakers and contactors).

The theoretical part explains the basic concepts, problems switching arc in a vacuum and is explained in detail the operating principles of vacuum interrupters. The following features define the difference between the vacuum circuit breakers and contactors, and there are also given examples.

In comparison part are given the different types of vacuum contactors largest producers in the EU, there is given a brief description of selected technical parameters and image. Everything is completed by their comparison. In the same way is given comparison of vacuum circuit breakers and in the end is once again made the comparison.
