中压真空断路器的专用型和多功能型

Multifunctional Type and Dedicated Type of Medium-voltage Vacuum Circuit Breaker

为了执行不同的开断任务，中压真空断路器出现了专用型和多功能型。专用型适用于某一开断任务，如高电压型、大电流型，频繁操作型，低过电压型；多功能型则赋于真空断路器更多的功能，如合-分-隔离-接地等功能。

In order to carry out differently opens breaks the duty, medium-voltage vacuum circuit-breaker to appear multifunctional type and dedicated type. Dedicated type is suitable in one opens breaks the duty, such as the high voltage, the large current mode, the frequent operation and lower over-voltage. Multifunctional entrusts with vacuum circuit-breaker more functions, such as closing, opening, isolating and earthing functions etc.
