Claims

[Scope of utility model registration request]

(1) In a buffer type gas breaker that extinguishes the arc generated between the contacts of the breaker part during the breaker operation by blowing compressed gas in the buffer cylinder through an insulated nozzle, the buffer cylinder The cross-sectional area of the gas passage formed from the outlet hole to the vicinity of the throat of the insulating nozzle is provided in a portion of the buffer cylinder outlet section where the buffer cylinder outlet hole does not exist (the wedge-shaped rectifying member and the inner wall of the insulating nozzle and the 1. A buffer type gas breaker characterized in that the movable arc contactor cover has a structure in which the outer wall of the movable arc contactor cover reduces the amount continuously and almost uniformly.

(2) The gas passage from the buffer cylinder outlet hole to the wedge-shaped rectifying member is substantially continuous and has the same shape, and the outer wall of the movable contact cover is made approximately parallel to the operating direction of the movable contact. On the other hand, in the inner wall of the insulating nozzle, the diameter on the buffer cylinder side is made thicker than the diameter of the part corresponding to the gas passage where the gas flow begins to curve toward the central axis (and these diameter parts are connected in a substantially straight line). , the outer wall of the movable arc contactor cover and the buffer cylinder side inner diameter part of the insulating nozzle are substantially continuously connected to the gas passage from the buffer cylinder outlet hole to the wedge-shaped rectifying member. The Pannor type gas breaker described in item (1).

(3) Make a counterbore hole in the side of the buffer cylinder of the wedge-shaped rectifying member, and attach the wedge-shaped rectifying member to the head of the bolt that fixes the movable arc contact support or the movable mark contactor cover to the buffer cylinder. A buffer type gas breaker according to claim 1 or 2, which is covered with an insulating nozzle and is pressed and fixed by the inner wall of an insulating nozzle.

(4) Utility model registration claim 1 or 2, in which the movable arc contactor cover and the wedge-shaped rectifying member are integrated and fixed to the buffer cylinder by sandwiching the movable arc contactor cover and the wedge-shaped rectifying member between insulating slurries. Buffer type gas breaker.

(5) A buffer-type gas breaker according to any one of claims (1) to 4, wherein the wedge-shaped rectifying member is made of an insulator.
