Connection time study for 400 kV circuit breakers with SF6

摘要

This paper presents the calculation of the time for the SF6 circuit-breaker operation by studying the voltage characteristic before connecting. Simulated on the basis of the switch characteristics and the factors that interfere with the time, i.e. the temperature and supply voltage of the breaker coil. Connecting the circuit breakers has a very important role in eliminating the vibrating and electrodynamic loading regimes in high voltage electrical networks.
