摘要： A contact assembly is provided for current-limiting low-voltage circuit breakers. The contact assembly has a two-armed contact lever swivel-mounted on a central bearing pin whose lever arms are equipped at their ends with contact pieces. The contact lever is equipped with a slot for mounting on the bearing pin whose longitudinal axis extends approximately at a right angle to the longitudinal axis of contact lever. The contact lever has a stop extending at approximately a right angle to its longitudinal axis for a catch swivel-mounted on the bearing pin. The contact forces on both lever arms cannot be influenced by the swivel mount or by the drive mechanism of the contact lever, but are determined exclusively by the biasing springs.

摘要： In an encapsulated, compressed gas-insulated high-voltage switchgear there is arranged in the interior of the encapsulation a drive and breaker units actuated by it. The breaker units are carried by a flange plate which closes the encapsulation off so that is is pressureproof. The flange plate is connected with the drive on the side away from the interior. To secure the position of the breaker units and hence also the coupling between them and the respective drive independently of the compressive stress of the flange plate, a substantially flat support plate is provided which directly receives the breaker units and which, extending parallel with the flange plate, is connected therewith via at least three parallel spacers which are arranged in a triangle.

摘要： The disclosure describes an air circuit breaker including a compression coil; a second spring holder to compress the compression coil in the axial direction thereof; and a first spring holder which is subjected to the compression force of the compression coil, the second spring holder being constructed in such a manner that it is formed of a plate material in a rectangular shape, a pair of projected pieces are provided on both sides of the plate material, and a pin is held to pass between the pair of projected pieces in the direction of thickness of the plate so as to be able to support one end of the energy accumulating spring at four points with the pair of projected pieces and the pin in a compressible manner. After compression of the energy accumulating spring by pressure application thereto, its pressure application is released to stretch the energy accumulating spring so as to close a pair of contact points through the first and second spring holders.

摘要： A circuit breaker having stationary and movable contacts operable between open and closed positions with the movable contact being biased in an open position. The movable contact is mounted to a contact and spring holder which engages one link in a toggle means. The first link is connected to a second link which has a drive pin secured thereto, and the second link is pivotally connected to a toggle lever. A cam is secured to a rotatable drive shaft, and the cam engages a cam roller which is secured to a follower plate. The follower plate, which rotates about an axis different from the drive shaft axis, has a drive pawl attached thereto, with the drive pawl being disposed adjacent the drive pin. Spring means are pivotally connected to the follower plate and are capable of being in spring charged and discharged positions. The spring is charged by rotation of the drive shaft and cam causing the cam roller to move outwardly. The outward movement of the cam roller causes rotation of the follower plate, resulting in charging of the spring means. The degree of rotation of the cam during the charging rotation is more than twice the degree of rotation of the follower plate, thereby gaining a mechanical advantage. When the spring means discharges, it causes rotation of the follower plate such that the drive pawl is capable of engaging the drive pin to move the toggle means into toggle position. Upon moving into toggle position, the toggle means moves the contact holder and movable contact into closed position. Also included are releasable toggle and drive latch means for holding the toggle means in toggle position and the follower plate in the spring charged position, respectively.

摘要： An electrical termination for use with a high voltage underground cable system wherein a large degree of arcing may occur between two electrical structures as they are brought together under short circuit conditions to complete a live high voltage circuit. Gas generating material is included as part of at least one of the structures such that gas is produced by the arcing between the structures as they are moved towards each other to form the desired electrical connection. The pressure build up of the gas within the termination acts upon a movable gas actuated means to cause movement thereof when the structures are brought close together under fault conditions. When moved by such a pressure build up, a portion of the gas actuated means transfers the arcing to a position away from the gas generating material to cause the cessation of gas production and thus permits the structures to couple and complete the circuit.

摘要： An electric power circuit breaker is disclosed wherein the latching mechanism as well as other parts which affect the motion of the contacts are returned by restoring forces to their initial position after the breaker is opened. The restoring forces are made ready in dependence on the position of the switching shaft of the breaker and are smaller in the closed position of the switching shaft than in the open position thereof. The invention is suited particularly for low-voltage power circuit breakers for high rated currents wherein the economic configuration of the required springs is of importance.
