1. high-voltage disconnecting circuit breaker comprises:

  • First contact and second contact;

    AndBe provided for described contact being moved to the device of the first phase mutual edge distance and being provided in described moving process, extinguishing the device that appears at any electric arc between the described contact, the functional of primary cut-out be provided thus, it is characterized in that;

    The described device that is provided for moving further is provided for after extinguishing any electric arc described contact moved to the second phase mutual edge distance greater than the described first phase mutual edge distance, provides the dielectric strength of high voltage isolator functional thus.
