Abstract
Korona je tinjavo izbijanje koje se javlja na površini vodiča. Zašto dolazi do korone? Kada jakost električnog polja oko vodiča prekorači električnu čvrstoću zraka dolazi do električnog izbijanja, gubitka energije i povećanja odvoda i tu pojavu zovemo korona. Pri temperaturi 25°C i tlaku 0.1 Mpa dielektrična čvrstoća zraka je 30 kV/cm. Znači, imamo neki vodič i podižemo napon na tom vodiču. U nekom trenutku kad napon bude toliki da jakost električnog polja na površini vodiča dosegne 30 kV/cm i prijeđe taj iznos, onda dolazi do ionizacije zraka, tj. zrak postaje vodljiv. Pri idealnim uvjetima (25°C i 0.1 Mpa = 1 bar) vrijedi: Eoko vodiča < Ez – nema korone Eoko vodiča > Ez – nastupa korona Efekti korone su „pucketav“ zvuk, plavičaste (modre) je boje i osjeti se miris ozona, a ozon je plin koji nastaje kao produkt ionizacije zraka.
Abstract (english)
Corona discharge is a tiny outburst that appears on the surface of the guide. Why is corona comming? When the strength of the electric field around the conductor exceeds the electrical strength of the air, electrical outflows, loss of energy and drainage increase occur, and this is called a corona discharge. At a temperature of 25 ° C and a pressure of 0.1 MPa of dielectric strength of air is 30 kV / cm. So, we have a guide and we get the voltage on that guide. At some point when the voltage is so high that the electric field strength on the surface of the conductor reaches 30 kV / cm and exceeds this amount, then air ionization occurs, ie the air becomes conductive. Ideal conditions (25 ° C and 0.1 MPa = 1 bar): Earound guide <Ez - no corona Earound guides > Ez - there is corona The effects of crowns are "crackly" sound, color of blue and the smell of ozone is felt, and ozone is the gas that is produced as a product of ionization of air.
