高压断路器是带有强力灭弧装置的高压开关设备，是供配电系统中重要的开关设

The high-voltage circuit breaker is a high-voltage switchgear with a powerful arc extinguishing device, and is an important switchgear in the power supply and distribution system. Its text conforms to QF. The high-voltage circuit breaker can not only open and close the normal line and the fault line, but also can connect and bear the short-circuit current for a certain period of time, and can automatically trip under the action of the protection device to remove the short-circuit fault.

High-voltage circuit breaker is a high-voltage switching device with a powerful arc-out device, and it is an important switching device in the power distribution system, and its text conforms to QF. High-voltage circuit breakers can not only open and close normal lines and fault lines, but also connect and withstand a certain period of short-circuit current, and can automatically trip under the action of the protection device to remove short circuit fault.
