Abstract

The bachelor thesis on the topic of measuring the heating of a circuit breaker processes the issue of heating of individual structural parts of the circuit breaker during the passage of current. The introductory section discusses basic quantities and laws that are important for the rest of the work. Subsequently, the issue of heating and types of heat transfer are analyzed. The work also includes a theoretical analysis and manufactured types of fuses and circuit breakers. In the practical part, the heating of the circuit breaker was measured using a thermocouple. The steady-state temperature value was determined from the measured data, from which the heating of the circuit breaker was calculated. The measurement curves are then displayed.
