摘要： This invention relates to a high ampere-rated circuit breaker which meets the electrical code requirements of the world market. The charging of the powerful operating springs controlling the circuit breaker contacts is made manually by a ratchet and pawl assembly. A logic plate interacts with the operating springs charging gear and a logic lever interacts with the ratchet and pawl assembly to prevent the charge indicating flag from signaling until the operating springs have become fully charged.

摘要： An actuator for the rapid connection and disconnection of a switch (10) has a primary shaft (12) , which can be rotated to and fro between a first end setting (18) and a second end setting (18') and possesses a tension lever (16). Seated in a rotationally secure manner on a delivery shaft (14) parallel to the primary shaft (12) is the drive shaft (22), which can be rotated, under the force of the spring-loading arrangement (26), from the disconnect setting (24) into the connect setting (24') and back. The spring-loading arrangement (26) includes a helical spring (28), which acts as a pre-tensioned compression spring and is supported by its spring ends (36, 36') on a respective butt strap (32, 34), which butt straps in turn interact, via driving stops (52, 54, 56, 58), with the tension lever (16) and the drive lever (22). A locking device supports the delivery shaft (14) in its disconnect and connect settings (24, 24') counter to the force of the helical spring (28), which can be tensioned upon the rotation of the primary shaft (12), until the primary shaft (12) has reached the corresponding unlatching setting.

摘要： A switching system for a step transformer having at least two adjacent taps and a pair of terminals shiftable between the taps has a pair of fixed contacts normally connected to the terminals, a vacuum interrupter connected between the terminals and displaceable between an open-circuit position and a closed-circuit position, a pair of movable contacts each engageable with a respective one of the fixed contacts and forming therewith a respective bypass switch, and a cam rotatable about a cam axis and having a contact face and an axially oppositely facing interrupter face each formed with a respective operating formation. A drive rotates the cam about its axis through steps of a half revolution. A respective cam follower engaged between each of the movable contacts and the contact-face formation opens and closes one of the bypass switches on rotation of the cam through a half revolution and thereafter opens and closes the other of the bypass switches on rotation of the cam through a succeeding half revolution. Another cam follower and a force storer engaged between the interrupter and the interrupter-face formation snap the interrupter open and then snap it closed each time the cam is rotated through a half revolution.

摘要： A multipolar circuit breaker having a lower case portion with side frame plates and a central frame plate facing the side frame plates on its two major sides, the central frame plate having a deep central groove which forms two flexible central frame plate arms each facing one of the side frame plates to form a nacelle sized to receive one of the switching mechanisms, each of the side frame plates and the arms of the central frame plate having, proximate to its free end, at-least-one inwardly facing protrusion, each of which is in a position opposed to the corresponding protrusion on the companion plate forming the nacelle and, after the respective switching mechanisms are installed, overlapping the side plates of each of the switching mechanisms, the arms of the central frame plate having been deflected to permit insertion of each switching mechanism, deflection in testing or use being prevented by inserting a high dielectric strength plastic stiffener in the groove separating the arms in the central frame plate, the lower case side frame plates having on their outer surfaces near the base of the lower case portion at-least-one retainer protrusion which cooperates with properly positioned openings in the upper case portion when that portion is in position covering the sides and top of the lower case portion to hold the upper case portion removably in that position, as a result of all of which the switching mechanisms may be checked for defects during production without assembling and then disassembling the circuit breaker.

摘要： An electric switch with a set of stationary contacts and a set of movable contacts situated on a contact bridge (30) between an IN-position and an OUT-position includes a forcibly guiding mechanism (32) for manual handling of the contact bridge (30) and an ejector mechanism (56) and a trip device (74) co-operating with the ejector mechanism, whereby the contact bridge (30) is automatically longitudinally displaced from its IN-position to its OUT-position when an overloading, a fault or a signal current is present. The forcibly guiding mechanism (32) and the contact bridge (30) are interconnected by means of a releasably blocking device in such a manner that the ejector mechanism (56) in the releasing state need only overcome frictional forces between the stationary and the movable contacts as the blocking device is released by means of the trip device (74). The forcibly guiding mechansim (32) and the ejector mechanism (56) co-operate in such a manner that the latter containing an energy reservoir such as a spring (64) is automatically reset before the contact bridge (30) can be forced to the IN-position. The forcibly guiding mechanism (32), in the form of an elbow joint, moves between two extreme positions and during such movement it passes a dead center. It includes a tilting spring (40) the potential energy of which after the passage of the dead center is utilized for charing the energy reservoir (64) of the ejector mechanism (56).

摘要： A circuit breaker actuator device of the type comprising an operating wheel (R) whose rotation drives the moving circuit-breaking members, said wheel being connected to a first spring (S'1) by a first chain (C1) passing over a first pulley (P1) and fixed to a first point (A1) close to the periphery of the wheel. The wheel is held fixed when the spring (S1) is under tension/compression by means of a retaining member (K1) which can be retracted to allow the wheel to rotate. The device further includes a second spring (S2) connected by a second chain (C2) passing over a second pulley (P2) and fixed to a second point (A2) on said wheel. The center of the wheel is situated, when both springs are under tension/compression, between the length of the first chain connecting the first point to the first pulley and the length of the second chain connecting the second point to the second pulley, with the second spring applying a force which is less than the force applied by the first spring.

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.
