Products Description
SF6 gas vacuum circuit breakers are high voltage circuit breakers that use a combination of SF6 gas and vacuum interrupter technology to extinguish arcs generated during the interruption of high voltage electrical circuits.
In these types of circuit breakers, SF6 gas is used as the insulating medium, while vacuum interrupters are used to interrupt the current when the circuit breaker is opened. The SF6 gas provides excellent electrical insulation and arc-quenching properties, while the vacuum interrupters provide high dielectric strength and reliable interruption of current.
When the circuit breaker is opened, the contacts inside the interrupter chamber separate and an arc is generated due to the high voltage. The SF6 gas rapidly absorbs the energy from the arc and extinguishes it, while the vacuum interrupter quickly interrupts the current, preventing re-ignition of the arc.
SF6 gas vacuum circuit breakers are commonly used in high voltage applications such as power transmission and distribution systems, as well as in industrial applications where high reliability and safety are required.
