On the project

Vědeckým cílem navrhovaného projektu je vytvoření numerického modelu vypínacího procesu, který přispěje k rozšíření a prohloubení poznatků o jevech probíhajících ve zhášecích komorách spínacích přístrojů na nízké napětí. Projekt je zaměřen na zkoumání interakce spínacího oblouku s obklopujícím prostředím, a přítomnosti elektrického, magnetického, teplotního a tlakového pole. V kombinaci počítačových metod s experimentálně získanými daty se jedná zejména o vyšetřování jednotlivých mechanismů transportu energie a možností jejich ovlivnění. Zvláštní pozornost bude věnována stanovení způsobu výpočtu radiačního transportu energie a jeho začlenění do modelování plazmatu spínacího oblouku. Vytvořený numerický model vypínacího procesu bude experimentálně ověřen na vzorcích reálných zhášecích komor. Závěrečné výsledky předkládaného projektu přispějí k lepšímu poznání chování spínacího oblouku během vypínání a následně i ke zlepšení provozních parametrů spínacích přístrojů na nízké napětí.

Description in English
The scientific aim of the proposed project is to prepare a numerical model of the switching process contributing to a wider and deeper knowledge of phenomena taking place in quenching chambers of low voltage circuit breakers. The project is concentrated on studies of the interaction of the switching arc with the surrounding environment with presence of electric, magnetic, thermal and pressure fields, respectively. Through a combination of computational methods and experimentally obtained data, significance of the individual energy transfer mechanisms and a possibility of influencing them will be analyzed. A special attention will be devoted to a prediction of radiation energy transfer and its integration to the switching arc plasma description. Developed numerical model of the switching process will be verified experimentally on real samples of the quenching chambers. Final results of the proposed project will be helpful for better understanding of the switching arc behavior during switching and consequently, for improving of operational parameters of low voltage switchgear.
