    摘要: According to an embodiment, a switchgear operating mechanism has a roller pin rotatably fixed to a leading end of a latch lever. A latch is fixed to a solenoid lever at a position different from the rotation axis of the solenoid lever, and has a leading end engageable with the roller pin. In a state where the switchgear operating state is shifted from the closed state to the cutoff state, the solenoid lever is pushed by an electromagnetic solenoid for cutoff so as to be rotated in an opposite direction to the biasing direction of the solenoid lever return spring, and the latch lever is rotated by a biasing force of the roller pin to release an engagement between the roller pin and the leading end of the latch, which causes a cutoff spring to discharge its energy to rotate the latch lever.

    摘要: In a power supply apparatus for discharge surface treatment which uses a green compact electrode as a discharge electrode, allows a pulse-type discharge to take place between said discharge electrode and a workpiece, and forms a film, which is made of an electrode material or a material obtained when the electrode material reacts to a discharge energy, on a surface of the workpiece following three measures are taken. (1) When a discharge voltage detected by the voltage detection means is less than or equal to discharge detection voltage set value which is slightly lower than a power supply voltage, the electric current cut-off means forcibly cuts off an output of the oscillator so that long-time pulse is prevented. (2) A capacitor is connected in parallel with an oscillation circuit of the oscillator, and the long-time pulse is prevented by capacitor discharge. (3) Time that the discharge takes place once is controlled by a timer so that the long-time pulse is prevented.
