摘要： A separating wall for dividing a heating volume of a power circuit into a first sub-volume and a second sub-volume. The separating wall is formed with at least one wall opening which allows a flow of gas between the sub-volumes. The wall opening has an aerodynamically active opening surface based on a pressure difference between a pressure in the first sub-volume and a pressure in the second sub-volume.

摘要： An electric circuit breaker device includes: a housing including an accommodating space inside; a projectile configured to be projected from a projectile accommodating portion toward an arc-extinguishing region portion side by energy received from the igniter; and a conductor piece provided at the housing and forming a portion of an electric circuit, the conductor piece including, at a portion of the conductor piece, a cutoff portion to be cut off by the projectile. The projectile includes, on a distal end side, a cutting-off surface configured to cut off the cutoff portion during actuation of the igniter. Of the conductor piece, at least one of a first surface facing a projectile accommodating portion side or a second surface facing the arc-extinguishing region portion side is formed with a cutting-off assisting groove at a predetermined expected cutting-off position where the cutoff portion is pressingly cut by the cutting-off surface during actuation of the igniter.

摘要： A circuit breaker, or transformer, or insulated bus for use with AC voltages greater than 30 kilovolts and AC currents greater than 400 amperes includes an elongated bushing made from electrically insulating material and having first and second ends. The first end of the bushing is coupled to a main enclosure of the circuit breaker, or transformer, or insulated bus and a terminal pad is coupled to the second end of the bushing. A conductor is disposed in an internal cavity of the bushing in spaced relation to an internal wall of the bushing that defines the internal cavity. The conductor includes first and second segments. A first end of the first segment is electrically connected to a contact of the circuit breaker, or transformer, or insulated bus and a first end of the second segment is electrically connected to the terminal pad. Second ends of the first and second segments are coupled together with a biasing element interposed between the second ends of the first and second segments. The biasing element is operative for biasing the first end of the first segment toward the contact and for biasing the first end of the second segment toward the one terminal pad.
