Claims

[Scope of utility model registration request]

(1) Equipped with a fixed arc contact and a movable arc contact that is attached to the fixed arc contact so that it can be moved toward and away from the fixed arc contact, and the arc generated when these contacts open and close is transferred to the fixed arc contact by a gas flow. In the gas spray breaker extending in the shape of a fountain inside the arc extinguishing chamber, a power supply side terminal plate supporting the arc extinguishing chamber, a load side terminal plate facing concentrically with a spaced interval from the power supply side terminal plate, and the above-mentioned A fixed arc contactor connected to a power supply side terminal plate, a buffer piston fixed concentrically to the side of the load side terminal plate near the power supply side terminal plate, and connected to a drive rod of a drive mechanism via an insulating rod. a rod passing through the load-side terminal plate and the buffer piston; a buffer cylinder support fixed to the inner end of the rod;
A communication pipe connected to the buffer cylinder support on the opposite side to the rod, a movable arc contact that can move toward and away from the fixed arc contact, a buffer cylinder that can slide on the buffer piston, and the buffer cylinder support A communication hole that communicates between the buffer chamber formed between the buffer cylinder and the buffer piston and the inside of the communication pipe, and a nozzle opening fixed to the power supply side terminal plate and provided at the fixed end thereof. A gas blowing breaker comprising: a pressure storage chamber made of an insulating material located outside the communication pipe concentrically with the communication pipe and within which the communication pipe can slide.

(2) A movable arc contactor is fixed to the tip of the communication tube opposite to the buffer cylinder support, and a communication hole is formed in the tip to communicate between the inside of the communication tube and the pressure storage chamber. The gas blow breaker according to item 1.

(3) The gas blow breaker according to claim 1 or 2, wherein the communication pipe and the buffer cylinder support are integrally formed.
