Моделирование процессов отключения токов короткого замыкания автоматическими выключателями токоограничивающего исполнения

Abstract

The article considers problems of modeling of short-circuit current interruption by a current-limiting automatic circuit breaker with an electrodynamic unit using a mathematical model developed on the basis of theoretical and experimental research. It allows modeling electric circuit opening, calculating Joule integral taking into account voltaic arc duration, determining the breaker opening time, and significantly decreasing volume of full-scale experiments.
