41 | Compact molded case circuit breaker with increased ampere rating | US546826 | 1990-06-29 | US5084689A | 1992-01-28 | Roger J. Morgan; Irenaeus S. Panus; Ronald G. Pekrul; Thomas F. Papallo, Jr.; Robert A. Morris; Henry J. Tucholski; Hamon L. Craft |
A compact molded case circuit breaker with increased ampere rating employs a latch assembly for maintaining the circuit breaker operating mechanism in a closed condition against a pair of powerful operating springs. To increase the mechanical advantage required to move the operating handle against the springs, a retractable handle extender is attached to the handle. For higher-rated circuit applications, a lug cover extension is added to the line end of the breaker to assist in extinguishing the intense arc that occurs during circuit interruption and to protect the line lugs from inter-phasal circuit faults. A visual access slot is arranged next to the circuit breaker handle to ascertain and verify the condition of the circuit breaker contacts. | ||||||

A multipole low-voltage circuit breaker with an insulating material housing and arc quenching chambers. By a new mechanical design, the installation of the arc quenching devices is to be facilitated. All arc quenching chambers of a switchgear are arranged in a quenching chamber housing which is subdivided by partitions and is fastened to the insulating material housing of a circuit breaker. The quenching baffles are fastened directly to the walls of the arc quenching chambers. A low-voltage circuit breaker with an insulating material housing of compact design is thus provided. | ||||||
43 | Air break contactor | US161235 | 1988-02-18 | US4843194A | 1989-06-27 | Miklos J. Orosz |
Access to the arc chutes of a contactor is provided by mounting the arc chutes along with insulating plates on the top surface of a frame which supports the parts of the contactor. A track is formed as a pair of grooves in a top surface of the frame. The arc chutes have projections on each side which fit into the grooves of the track so that the arc chute may stand on the top surface of the frame of the contactor. Insulating plates are mounted in sockets made into the top surface of the frame and provide electrical insulation for the arc chutes. | ||||||

51 | Arc extinguish chamber device of multielectrode circuit breaker | JP8858388 | 1988-04-11 | JPH01251523A | 1989-10-06 | KOBANAWA AKIHIKO |
PURPOSE: To assemble the title device into a multielectrode circuit breaker at one time so as to simplify assembling work by forming multiple electrodes integrally by means of molding. CONSTITUTION: In a multielectrode circuit breaker whose multielectrode breaking mechanism is received in the case of an insulator, arc extinguish chamber portions 2 of respective electrodes and connecting arms 3 which connect the arc extinguish chamber portions 2 with each other are integrally molded and formed. The multiple electrodes are integrally formed by molding like this, and thereby even the multielectrode circuit breaker can be put together at a time. In addition, making the most of the advantage of the processability of mold forming, it is easy that the arc extinguish chamber portion 2 is formed into a box shape with a very small opening. With this arrangement that it is formed into a box shape, the pressure of arc gas at the time of breaking is received in the arc extinguish chamber portions 2 in a moment so as to soften the pressure putting on the case.

PURPOSE: To prevent water from being exposed at the portion where a current flows even when a power switch is kept off in the magnetically operated power switch provided with an electric contact piece and a magnetically attracting member in the sealed first chamber and provided with a magnet member and an operating member in the adjacent second chamber. CONSTITUTION: This magnetic switch 20 is composed of a two-chamber housing 22 formed with a sealed lower chamber 24 and an adjacent opened upper chamber 26. A magnet 82 is revolved around pins 98, 100 between the closure position and open position. The magnet 82 is normally held at the open position by a deviation spring 110 provided between the rear face of the magnet 82 and the cross sectional wall of the upper chamber 26. When the extension section 120 of a slide cap and a cam 122 are moved, the cam 122 is retained in the recess 120, the magnet 82 is revolved apart from a separating wall 28 by a lift spring 110, and the switch 20 is opened. The magnetic force between the magnet 82 and metal plates 44, 46 surmounts the deviations of plate springs 34, 36 to attract the metal plates 44, 46 upward, moving electric contact pieces 34, 36 are brought into electric contact with static contact pieces, and the magnetic switch 20 is set to the closure position. | ||||||

PROBLEM TO BE SOLVED: To provide a three-phase large-current switchgear which has dipole per phase with magnetic compensation circuits. SOLUTION: A three-phase switchgear 10 which has two adjoining poles per phase is provided in inside poles 26, 32 of each side phase with magnetic compensation circuits 82 designed so that the power distribution between two poles 24, 26 and 32, 34 of each side face phase may be optimized in equilibrated three-phase actuation. By this arrangement, currents which flow to either two poles of the side face phase are equilibrated, in particular by reducing the current intensity and temperature of the inside poles 26, 32 of the side face phase.
