    摘要： An electromagnetic repulsion drive switching device in which a contact-closing coil and a contact-opening coil are arranged to confront a conductive repulsive member, and in which a drive current is fed to a selected one of the individual coils from a capacitor charged to a predetermined charge voltage by a charging power source. A stationary contact and a movable contact are brought into and out of contact by a repulsion electromagnetic force generated between the coils and the repulsion member. A voltage control controls the output voltage of the charging power source so that the peak value of the drive current may fall within a range with respect to a temperature change of the capacitor. As a result, even if the working temperature of the capacitor changes, the drive current of the contact-closing coil and the contact-opening coil falls within a desired range.

    摘要： A switching apparatus includes a switch, a movable coil, stationary coil members, and a direction-of-conduction setter comprising diodes. The switch has a stationary electrode. The movable coil is fixedly mounted on a movable shaft coupled to the movable electrode. The stationary coil members are opposed to the movable coil. The power supply supplies an excitation current to the coils. The direction-of-conduction setter sets the direction of conduction, in which the excitation current flows from the power supply into the coils, so that the coils will electromagnetically react on each other. This arrangement provides highly efficient electromagnetic driving. Moreover, an opening power supply or closing power supply is required to have only a small capacity.

    摘要： In a switchgear, by using a spring with a varying spring constant from closing to electrode opening as a loading spring, spring load in the opened electrode state is made smaller than a spring load in the closed electrode state to decrease the energy required from electrode closing up to electrode opening. Moreover, by using a spring in which a load in the opposite direction to a load in the closed electrode state works in the opened electrode state, the opened electrode state can be held securely.

    摘要： A fast changeover from one power system to another in the event of an irregularity in the power source system substantially reduces operating costs by minimizing a power loss in switches during conduction, dispenses with a cooling device for cooling a thyristor switch, and implements the thyristor switch in a compact and low-cost design. The power supply system for a load includes one switching apparatus for connecting a load to one power source system, and another switching apparatus for connecting the load to another power source system. Each of the switching apparatus includes a pair of thyristors connected in anti-parallel and a mechanical switch connected in parallel with the thyristor pair. The thyristor pairs and the mechanical switches are controlled so that the mechanical switches conduct a load current when the load is supplied with power from the one power source system in a steady power supply state. The thyristor switches conduct the load current during a power source changeover time within which the load is disconnected from one power source system and connected to the other power source system, and do not conduct the load current during the steady power supply state.
