Použití přístrojů s plynem SF6 na Dolech Bílina.

Abstract

The subject of my work is the use of devices for gas with SF6 at Doly Bilina. The first part deals with the introduction to the historical development of medium voltage circuit breakers. I also explain what a switch and what requirements are placed on him . Then I make a basic division switches and at the end of the first part I will explain what is an electric arc, why is undesirable and how to extinguish . In the second part I have been dealing with SF6 circuit breakers , SF6 gas development , the characteristics of SF6 gas , a brief historical development of circuit breakers using SF6 gas and arc quenching principles . In the third section I describe the instruments used to Doly Bilina, which are used , how they are used and what needs to require operation and maintenance.
