摘要： A limited flash-over electric power switch uses a dielectric gas regulator and a flash-over arrestor to greatly diminish the occurrences of high voltage flash-over during operation of a circuit interrupter. The dielectric gas regulator prevents the flow of the dielectric gas into the arc gap during an initial portion of the opening stroke of the interrupter contacts. Once the arc gap is sufficiently wide to greatly diminish the likelihood of a high voltage flash-over, the dielectric gas regulator allows the dielectric gas to flow into the arc gap to extinguish the arc. The flash-over arrestor snubs out incipient flash-over that may occur as the arc attempts to reform across the arc gap. The flash-over arrestor may be a conductive ring located on the interior surface of the nozzle in the region of the orifice.

摘要： An electric power switch suitable for use as a capacitor switch that includes a drive unit having a bi-directional toggle mechanism and linearly opposing opening and closing spring latches. The opening and closing spring latches are located on opposing sides of the toggle mechanism, which includes an open-cage spring mechanism with coaxial, nested opening and closing springs operated by a rotating, motor-driven charging cam. To open the circuit interrupter, the opening spring latch is tripped to release the opening spring and thereby remove the capacitor bank from the electric power circuit. To introduce the capacitor bank into the electric power circuit, the motor rotates the charging cam through one complete rotation, which charges the opening and closing springs and trips the closing spring latch to release the closing spring to close the circuit interrupter and thereby introduce the capacitor bank into the electric power circuit.
