| PROBLEM TO BE SOLVED: To provide a fuse assembly for rapid interruption of a specific fault current. SOLUTION: In this fuse assembly, a plurality of foil elements 6 are extend between a pair of terminals 2, 4 and are physically supported by a plurality of splitter plates 8. A pair of parallel bus bars 12, 14 are connected in series with the foil elements 6 and generate a magnetic field that is substantially perpendicular to the current flowing in the foil elements. When a specific fault current is generated, an electromagnetic force developed as a result of interaction between a magnetic field B and an arc current pushes molten foil elements into spaces among the splitter plates. As a result, the arc length is increased, and hence the arc voltage is increased. At least the foil elements and the splitter plates are immersed in flowing liquid dielectric. The liquid dielectric may help to push the molten foil elements into the spaces among the splitter plates and remove foreign matter away from the arc site. COPYRIGHT: (C)2010,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 | ||||||

| PURPOSE: To maintain a switch contact in the closing condition with a power, and reduce the power for opening the switch contact by generating the power with a current flowing in a contact assembly. CONSTITUTION: A fixed contact 36 connects both legs 40 of a L-shaped members 37, 38 to each other through a contact bridge member 44. A conductive arm 48 having continuous parts 50, 52 extended in the direction from the legs 42 to the member 44 is provided. A part 52 is extended between the L-shaped members 37, 38, and the contact bridge member 44 and a movable contact arm 82 are connected to each other at the time of closing a switch 14. An arc runner 54 is fitted to the part 52 of the conductive arm 48 provided at a position adjacent to the contact bridge member 44. The bridge member 44 is provided with a contact pad 46 so as to abut on a pad 46 of the arm 48. Direction of the current flowing in the pads 46, 48 is supplied to a quick distinguishing device 100. With this structure, the arc runner eliminates the work of the dynamo-electric force to an arc to be generated when the contact is turned off, and the arc is led into an arc chamber without generating hindrance, and the dynamo-electric force for opening the switch can be reduced.
