106	Circuit breaker having closing resistor	US15383025	2016-12-19	US09997321B2	2018-06-12	Jong-Hyuk Lee
Disclosed herein is a circuit breaker having a closing resistor, which is capable of preventing impact caused when the circuit breaker is opened and closed from being transferred to peripheral structures. The circuit breaker having a closing resistor includes a fixed part having a fixed contact, a movable part having a movable contact, a closing resistor unit connected to the fixed part and having a closing resistor unit contact, a closing resistor movable part connected to the movable part and having a closing resistor movable contact, and a support structure slidably coupled to the closing resistor unit in a direction parallel to a movement direction of the closing resistor movable part, thereby enabling impact and vibration applied to the closing resistor unit to be absorbed by the support structure.

108	Arc extinguishing contact assembly for a circuit breaker assembly	US14469614	2014-08-27	US09305726B2	2016-04-05	Koustubh Dnyandeo Ashtekar; James Jeffery Benke
An arc extinguishing contact assembly for a circuit breaker assembly is provided. The arc extinguishing contact assembly includes a fixed contact assembly, a movable contact assembly and an arc extinguishing assembly. The fixed contact assembly includes a fixed arc contact assembly, a fixed main contact assembly, and a number of movable, intermediate arc contact assemblies. The movable contact assembly includes a movable arc contact assembly and a movable main contact assembly. The arc extinguishing assembly is structured to extinguish an arc generated as the movable contact assembly moves between an open, first position and a closed, second position.
109	CIRCUIT BREAKER	US14343295	2011-09-20	US20140224772A1	2014-08-14	Shuichi Tanigaki; Daisuke Yoshida; Tomohito Mori
A circuit breaker includes: a first arc-extinguishing chamber and a second arc-extinguishing chamber that interrupt a current by opening contact points and extinguish an arc during the current is being interrupted; and a connection unit that connects the first arc-extinguishing chamber and the second arc-extinguishing chamber to each other. The first arc-extinguishing chamber and the second arc-extinguishing chamber are connected to the connection unit in such a manner that shaft lines of the arc-extinguishing chambers form an angle of substantially 90 degrees. The first arc-extinguishing chamber is arranged on a side of the connection unit in such a manner that the shaft line thereof is substantially horizontal, and the second arc-extinguishing chamber is arranged on an upper side of the connection unit in such a manner that the shaft line thereof is substantially vertical.
110	Valve for gas circuit breaker and gas circuit breaker with the same	US12879047	2010-09-10	US08299385B2	2012-10-30	Chae Yoon Bae; Joung Ung Choi
Disclosed are a valve for a gas circuit breaker, and a gas circuit breaker having the same. The gas circuit breaker comprises a cylinder constituting appearance of the gas circuit breaker, and providing a gas flow path therein, a partition plate having passing holes, and configured to partition inside of the cylinder, a sleeve concentrically disposed in the cylinder, a valve body inserted into the sleeve, and mounted below the partition plate so as to perform a reciprocation along the sleeve, an elastic means configured to upwardly apply an elastic force on a bottom surface of the valve body, and a blocking plate inserted into the sleeve, and mounted between the valve body and the partition plate so as to be moveable in upper and lower directions, wherein the valve body is provided with discharge openings, and the discharge openings are open and closed by movements of the blocking plate.
111	Gas exhaust for circuit breaker	US11649397	2007-01-03	US20070158310A1	2007-07-12	Wolfgang Grieshaber; Victor Hermosillo; Charles R. Hilland; Daniel Schiffbauer
The gas exhaust comprises a generally cylindrical shaped casing (26) closed by a bottom (18, 22) at one end and with openings (30) to allow gas to escape. A duct (16) is arranged in the casing (26) to delimit a central passage inside the duct, and an annular passage (42) surrounding the central passage (40) outside the duct between it and the casing (26). There is a communication consisting of four holes (20) in the duct (16) close to the bottom (18) to form a communication between the central passage (40) inside the duct (16) and the annular passage (42). The casing (26) includes two diametrically opposite openings (30) located in a horizontal plane.
112	Compressed-gas circuit interrupter having a pair of rapid transfer insulating nozzles	US3670126D	1969-07-01	US3670126A	1972-06-13	ROIDT ROBERT M
A gas-blast type of circuit breaker is provided having a pair of separable contacts with a pair of contractable insulating nozzles disposed closely adjacent the point of separation of the separable contacts. In one embodiment of the invention, there is provided a pair of tubular separable contacts, through which the gas exhausts, and a pair of spaced contractable insulating nozzles are provided to locate the arc quickly axially and to control the gas-flow conditions.
113	Gas-blast circuit interrupters with lateral venting action	US3555227D	1968-10-21	US3555227A	1971-01-12	CROMER CHARLES F; CROOKSTON RONALD W
A gas-blast type of circuit interrupter is provided having an arcing chamber of insulating material with rows of lateral venting slots, serving as splitters. A cluster of stationary contact fingers within the arcing chamber make separating engagement with a tubular movable contact. A stationary hollow insulating arc plug is provided interiorly of the arcing chamber, within which gas is forced to flow. The arcing plug has lateral inlet slots provided therein, which emit arcing gas under pressure into the interior of the arcing chamber and laterally outwardly across the arc, and radially outwardly through the lateral slots provided in the stationary insulating arcing chamber. The arc is moved by the radial outward blast to be forced against the arcing splitters provided by the sidewalls of the stationary insulating arcing chamber. As an alternate arrangement, a side lateral dump is provided adjacent an elongated arcing contact finger, at which the arc is constantly drawn. This prevents the accumulation of stagnant ionized gases and arc products, which may otherwise accumulate in the pocket surrounding the annular stationary contact finger assembly.
