PROBLEM TO BE SOLVED: To improve a circuit breaker so as to be able to alleviate the abnormal wear of contacts by moving an arcing point of a movable contact from its surface to the tip side of a movable contactor with high interrupting performance secured by effectively exerting a narrow-gap effect by a narrow-gap arc-extinguishing plate, by suppressing an excessive internal pressure rise by lowering a total volume of thermal decomposition gas generated at current interruption, and by a tactful use of a gas flow of the thermal decomposition gas.
SOLUTION: In the circuit breaker with a pair of narrow-gap arc-extinguishing plates 9 formed of insulating materials arranged at right and left sides of fixed and movable contacts along a pole-opening movement path of a rotating movable contactor 3 paired with a fixed contactor 2, and with a narrow-gap arc-extinguishing space formed between opposed wall faces, the narrow-gap arc-extinguishing plates are arranged along the whole length of the pole-opening movement path, and at the same time, with the narrow-gap arc-extinguishing space between the opposed wall faces divided into an area near the fixed contact and an open-pole side area ahead of it, the narrow-gap interval in the area near the fixed contact is set narrow, a lateral stepped part 9a and a longitudinal stepped part 9b are formed on a plate face at the open-pole side area, and a narrow-gap-enlarged face 3c is formed at a narrow-gap interval enlarged at a surface area ahead of the movable contact 3a.

<P>PROBLEM TO BE SOLVED: To provide a circuit breaker of a double-break mechanism capable of prolonging the service life of a contact and prevent contact failure between contacts in a closed state by suppressing abnormal wear of the contact caused by an arc generated between fixed and movable contacts when a current is interrupted. <P>SOLUTION: The circuit breaker of the double-break mechanism includes a contact mechanism of a current interrupting section having first and second fixed contact shoes 1, 2 arranged in parallel side by side, and a rotation type bridging movable contact shoe 3 having movable contacts 3a, 3b, which face to fixed contacts 1a, 2a fixed on tip ends of the respective fixed contact shoes, and are fixed on a U-shape arm tip end, and an arc extinguishing device combined with them. A magnetic plate 6 is interposed in a middle of the two pairs of the fixed and movable contacts arranged side by side along an opening movement path of the movable contact shoe 3. Magnetism between arcs generated between the contacts of left and right pairs is shielded by utilizing the magnetic plate as a magnetic shield, and offset movement of an arc generating point on the contact is prevented when the arc generating point is affected by action of electromagnetic force. <P>COPYRIGHT: (C)2008,JPO&INPIT |

<P>PROBLEM TO BE SOLVED: To increase the number of magnetic plates in an arc-extinguishing chamber and to effectively use the uppermost magnetic plate when the uppermost magnetic plate is positioned higher than a tip of a moving contact at a contact parting position. <P>SOLUTION: An insulating member 20 having a pair of side walls 21 covering a moving track 28 of a moving contact 9 from both left and right sides is mounted inside both leg parts of each of a plurality of the magnetic plates 15 in the arc-extinguishing chamber 13; the tip of the moving contact 5 at the contact parting position is projected from the upper surfaces of the side walls 21 of the insulating member 20; and the upper corner parts 21a of the side walls 21 on the magnetic plate 15 side are extended to the vicinity of the uppermost magnetic plate 15. Thereby, an arc having moved to the tip of the moving contact 5 is pushed out to an external space larger than a space between the left and right side walls 21, and the arc having escaped from the upper corner parts 21a can be properly extended by guiding it to the uppermost magnetic plate 15. <P>COPYRIGHT: (C)2006,JPO&NCIPI |

PROBLEM TO BE SOLVED: To break an arc of a large diameter produced by a large fault current in an intermediate voltage, while preventing the possibility of the bursting of an arc-extinguishing chamber.
SOLUTION: This circuit breaker comprises a fixed contact means 20, a movable contact means 22, and an arc-extinguishing chamber 24. The arc- extinguishing chamber 24 has two side-fase flanges 68, a separator 78, the front opening formed near a contact region of the fixed contact means 20, a lower arc horn 34, an upper arc horn 96, and a set of side dielectric shields 100 limiting laterally the front opening 76 of the arc-extinguishing chamber. Each dielectric shield 100 is arranged laterally so as to be fitted between the separator 78 and the movable contact means 22 at an open position. The set of dielectric shields 100 are installed to clearly reduce a width of the front opening of the arc-extinguishing chamber 24 at a side nearer to the upper arc horn 96, in comparison with that at a side nearer to the lower arc horn 34.

PROBLEM TO BE SOLVED: To provide an electric circuit safety device having a gas generation motor device for expelling an electric arc from a contact during opening action.
SOLUTION: An electric circuit safety device 10 has a housing 18, an operation mechanism 63 arranged within the housing 18, and first and second main contacts 62, 64 capable of freely opening. An insulating support member 246 is arranged within the central region between the doubly folded parallel parts of a conductive first contact supporting member 68 supporting a fixed contact. The insulating support member 246 is positioned on the outside of the central region, and has a part insulating and shielding the supporting member 68 from an arc product. The insulating support member has the top and bottom, which support a magnetic material in a closed loop state by co-operation, a closed loop surrounds all of the top of the fixed contact, a fixed contact supporting body, and a moving contact supporting arm so as to be capable of achieving the operation of a slot motor. The insulating support member is made of a gas generating material, gas is generated by heat of an arc during opening action of the contact, and expels the arc from the contact during opening into an arc chamber.

PURPOSE: To prevent damage of a fixed contactor, and enhance breaking performance by installing a grid support by fitting its leg part in a U-shaped hole of the fixed contactor, and respectively covering upper surfaces of outside and inside electric current passages with side walls and a sheathing. CONSTITUTION: A grid support 12 is composed of a pair of left and right side walls 12a crossing at right angles so as to be opposed to each other, a sheathing 12b extending between lower end parts, a leg part 12c projecting from bottom surfaces of the side walls 12a, a connecting plate extending over an upper part and a wall plate suspending from a bottom surface, and is integrally molded by melamine type mold molding resin. An arc-extinguishing grid 6 is pressed in and fixed to a multistage groove inside of the side walls 12a, and the support 12 is installed by fitting its leg part 12c in a U-shaped hole 9 of a fixed contactor 1 on both sides of a fixed contact point 3. Since an upper surface of an outside electric current passage 1a of a contactor 1 with the bottom surfaces of the side walls 12a or an upper surface except the contact point 3 of an inside electric current passage 1b is covered with the sheathing 12b, the contactor 1 is shielded from an arc, and wear and tear can be reduced. |

PURPOSE: To use a same structure for a higher voltage without increasing sizes, by disposing insulation boards each having a through hole for a link on both sides of an insulation shield on the connecting link leaving a space equal to a maximum distance in a breaking process.
CONSTITUTION: Because motion of a connecting link 26 can be regarded substantially as a linear motion, a clearance gap between it and a through hole of each of insulation boards 31, 32 can be minimized. An insulation shield 30 fixed to the link 26 stands by the insulation board 32 when a contact units 4, 5 are in a closed position, and only a very little breaking gas, in a breaking process, passes through the though holes, takes a circuit round the shield 30, and reaches a space between it and the insulation board 31. At last, in a terminal position where the units 4, 5 are opened, the shield 30 makes direct contact with the insulation board 31 or stands opposite to it leaving a slight space, and the through holes are substantially closed. Accordingly, the shield 30 closes the through holes of the two insulation boards 31, 32 covering the entire breaking process, and a higher voltage can be cut off.
