    • The present invention relates to a hybrid extinction-type gas circuit breaker, which can reliably eliminate an arc when a fault current is cut off, without a loss of pressure in the extinction gas. The hybrid extinction-type gas circuit breaker of the present invention comprises: a fixed unit having a fixed unit arc contact portion; and a moving unit including a cylinder, a piston arranged in the cylinder, a puffer chamber and a thermal expansion chamber formed by a separator wall, and an operating rod which passes through an interior of the piston and the cylinder, the moving unit further including a moving unit arc contact portion that can closely approach the fixed unit arc contact portion. A moving valve is arranged at one surface of the separator wall, wherein the moving valve includes a tight contact portion and a moving portion. The tight contact portion is movable by means of a difference in pressure, and is brought into tight contact with the separator wall. The moving portion extends from the tight contact portion, enables the operating rod to penetrate therethrough, and opens/closes the thermal expansion chamber.
    • 本发明涉及一种混合消光型气体断路器,其能够在故障电流被切断时可靠地消除电弧,而不会消耗气体中的压力损失。 本发明的混合消弧型气体断路器包括:具有固定单位电弧接触部分的固定单元; 以及移动单元,其包括气缸,布置在气缸中的活塞,由分隔壁形成的缓冲室和热膨胀室以及穿过活塞和气缸的内部的操作杆,移动单元还包括 移动单元电弧接触部分,其能够接近所述固定单元电弧接触部分。 活动阀布置在分离器壁的一个表面处,其中活动阀包括紧密接触部分和移动部分。 紧密接触部分能够通过压力而移动,并且与分隔壁紧密接触。 移动部分从紧密接触部分延伸,使得操作杆能够穿过其中并且打开/关闭热膨胀室。
