能を向上する方法が望まれる。Buffer-type gas circuit breakers using SF and gas, which have excellent arc-extinguishing properties, are the mainstream. However, this circuit breaker has the property that the interrupting characteristics are significantly influenced by the rate of change in current (di/dt) immediately before interrupting the IT flow and the rate of change in transient recovery voltage (dv/dt) immediately after interrupting the current. Therefore, as the breaking current increases, d
Short-range line faults (SLF) where v/dt increases, disconnection failures called thermal breakdowns occur in disconnection duties that include transient recovery voltage (ITRV) of high frequency components that occur due to the power side bus conditions of the circuit breaker. There are defects that are likely to occur. For this reason, there are performance concerns regarding an increase in the interrupting current as the system expands, or when the interrupting current includes harmonic current. However, replacing all conventional circuit breakers would be very expensive. Therefore, a method to improve the performance of conventional circuit breakers is desired.

ない。このため。By the way, the vacuum interrupter has very excellent insulation recovery characteristics, and even when interrupting a large current, the failure occurs when a certain amount of voltage is restored between the poles after the interrupt, resulting in recovery breakdown. There is no thermal damage seen in gas circuit breakers. For this reason.
