    • A vacuum type circuit breaker which has an operating lever (31) connected at one end thereof to the movable electrode (102) of a vacuum switch tube (1) and at the other end to a closing spring (55) through an energy storage link mechanism (54). The operating lever (31) functions to drive the movable electrode (102). The energy storage link mechanism (54) is provided with an energy storage crank (52) pivotally supported on a shaft (2051). The force which the energy storage link mechanism (54) applies to the operating lever (31) is set such that it is less than a force on the operating lever (31) which is produced by the difference between the internal pressure of the vacuum switch tube (1) and atmospheric pressure. This arrangement makes it possible, upon occurrence of vacuum loss, to detect the vacuum shortage, whereupon the closing of the switch is prevented to thereby avoid an accident due to vacuum degradation.
    • 一种真空式断路器,其具有在其一端连接到真空开关管(1)的可动电极(102)的操作杆(31),另一端通过能量存储连杆 机构(54)。 操作杆(31)用于驱动可动电极(102)。 能量存储连杆机构(54)设置有枢转地支撑在轴(2051)上的储能曲柄(52)。 能量存储连杆机构54施加到操作杆31的力被设定为小于由真空开关的内部压力之间的差异产生的操作杆(31)上的力 管(1)和大气压力。 这种布置使得在发生真空损失时可以检测真空不足,从而防止开关的闭合,从而避免由于真空劣化而引起的事故。

    • In one embodiment, a fixing apparatus is configured of a pressing portion for causing the pressure roller to enter a pressure applied state by applying bias, a switching portion for causing the pressing portion in the pressure applied state to enter a pressure released state by causing a cam to rotate forward, a pressure state detection portion for detecting the pressure released state, and a control portion for, when shifting from the pressure applied state to the pressure released state, turning forward the cam of the switching portion in the pressure applied state and stopping the cam after the pressure state detection portion detects the pressure released state. If the cam is turned forward with respect to the switching portion for a certain time period, but the pressure state detection portion does not detect the pressure released state, the control portion performs forward rotational direction retry control.
