Abstract:V diplomskem delu sta obravnavana razvoj in validacija numeričnega modela faznega dela kombiniranega zaščitnega stikala z nadtokovno zaščito (KZS). Namen raziskave je zajemal izdelavo numeričnega modela, s katerim si lahko pomagamo pri razvoju komponent, kot je kontaktni sistem. Uporabljena raziskava je bila prav tako v pomoč pri analizi elektromagnetnih vplivov v primeru kratkega stika. Za potrebe raziskave je bila uporabljena programska oprema COMSOL Multiphysics, s katero je bila izvedena simulacija tokovne sile na gibljiv kontakt, prav tako so bile določene minimalne mehanske zahteve za zanesljivo delovanje. Rezultati simulacij so bili validirani z eksperimentalnimi podatki, kar je omogočalo nadaljnjo uporabo modela pri načrtovanju in optimizaciji podobnih sistemov.
Keywords:Kombinirano zaščitno stikalo (KZS), COMSOL Multiphysics, električni oblok, numerični model.

Title:Development and validation of a numerical model of the circuit-breaking part of a residual current circuit breaker with overcurrent protection (RCBO)
Abstract:The thesis focuses on the development and validation of a numerical model of the circuit-breaking part of a residual current circuit breaker with overcurrent protection (RCBO). The main objective is to create a numerical model that can support the development of components such as the contact system and enable analysis of electromagnetic effects during a short circuit. COMSOL Multiphysics software was used to simulate the current force acting on the moving contact and to determine the minimum mechanical requirements for reliable operation. The simulation results were validated with experimental data, enabling further use of the model in the design and optimization of similar systems.
Keywords:Residual current circuit breaker with overcurrent protection (RCBO), COMSOL Multiphysics, electric arc, numerical model.
