Claims

[Claims for Utility Model Registration] A fixed side arc contact, a movable side arc contact that moves into and out of contact with the fixed side arc contact, a buffer chamber that compresses arc-extinguishing gas, and a stationary side arc contact that an insulating nozzle having a throat portion to be inserted, and an arc generated between the fixed side arc contact and the movable side arc contact at the time of disconnection, and an insulating nozzle in the buffer chamber due to the opening operation of the movable side arc contact. In a buffer type gas breaker in which compressed arc-extinguishing gas is guided and blown through an insulated nozzle, the tip of the fixed arc contact is provided with an outer diameter equal to or less than the outer diameter of the fixed arc contact. An insulating rod is provided facing the movable arc contact, and the length of the insulating rod is such that it is inserted into the throat of the insulating nozzle at the initial stage of the breaker operation. .
