    • PURPOSE: A sealed type switching device is provided to reduce an offset load at the surface of a contact and friction force at the support of a movable side current carrying shaft by reducing vibrations of the movable side current carrying shaft and a movable side contact of a vacuum valve. CONSTITUTION: A vacuum valve(2) having a pair of switching contacts(4,5) is disposed in a gas tank(1) filled with insulation gas, and one end of a movable side current carrying shaft(9) is integrally connected to the movable side contact(5) of the vacuum valve. A contact pressure adjusting spring(19) is arranged at the other end of the movable side current carrying shaft. An operating rod(17) is arranged to penetrate through the gas tank. An operation mechanism unit(18) for carrying out switching operation of the vacuum valve is attached onto the operating rod arranged outside the gas tank. An insulation rod(11) for electrical insulation between the operating rod and the contact pressure adjusting spring is attached onto the operating rod inside the gas tank. The contact pressure adjusting spring is bonded to the insulation rod.

    • PURPOSE: A metal-enclosed switchgear using a vacuum valve is provided to reduce a size of a tank by removing a supporting insulator for fixing a bus conductor to the tank. CONSTITUTION: A metal-enclosed switchgear includes a metal body(1) for storing a vacuum valve, an insulator tube(8), and a disconnector. The insulator tube is fixed at one end of the axial direction of the metal body. The insulator tube includes a bus line fixing part(8b) in order to insulate and support a bus conductor. The vacuum valve(7) is fixed to the inside of the insulator tube and includes a movable electrode rod and a stationary electrode rod. The disconnector includes a blade support member connected electrically to the movable electrode rod through a connecting conductor(13), a bus line terminal fixed and connected to the bus-side conductor, and a blade(12). The blade is attached to the blade support member and separated from the bus line terminal in order to be operated as a disconnecting element.
    • 目的:提供一种使用真空阀的金属封闭开关柜,通过拆下用于将总线导体固定到水箱的支撑绝缘体来减小水箱的尺寸。 构成:金属封闭开关装置包括用于储存真空阀的金属体(1),绝缘体管(8)和隔离开关。 绝缘子管固定在金属体的轴向的一端。 绝缘子管包括总线固定部分(8b),以便绝缘并支撑总线导体。 真空阀(7)固定在绝缘子管的内部,并包括可动电极棒和固定电极棒。 断路器包括通过连接导体(13)电连接到可动电极杆的电子支撑构件,固定并连接到总线侧导体的总线端子和叶片(12)。 叶片附接到叶片支撑构件并与总线端子分离,以便作为断开元件操作。
