摘要： PROBLEM TO BE SOLVED: To provide a switching apparatus which is capable of extinguishing an arc stably in a low current region as well as in a high current region by improving arc-extinguishing performance. SOLUTION: In this switching apparatus, each base end of a movable blast member 201 and a drive link 24 is attached rotatably to a pivoted part 45 as the center of rotation which is located on the side of a movable electrode 21. In open-circuit operation, when the movable electrode 21 reaches a predetermined opening position and stops the driving of the drive link 24, the movable blast member 201 rotates about its base end as the center of rotation toward the moving direction of the drive link 24 by inertia force. At that time, a gas flow flowing to the arc extinguisher 17 is generated, and the wind pressure of the gas flow increases the movement of an arc I to the back of a magnetic plate 110. This is especially effective for breaking an arc I generated in a minute electric current region because electromagnetic force generated in a magnetic plate 110 is not strong. Consequently, stabilization of an arc I is promoted in a minute electric current region, thereby achieving a stable current breaking performance. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a heat storing device to prevent leakage of a heat storing material to an external part. SOLUTION: A heat storing device 11 comprises a container body 12 the internal part of which is filled with a heat storing material 16; a heater 18 to heat the heat storing material 16; and a heat transfer pipe 17 through which a heating medium flows and which is disposed in the container body 12 and which performs heat-exchange between the heat storing material 16 and the heating medium. The heat transfer pipe 17 and the heater 18 are led out to an external part through the upper surface, making no contact with the heat storing material 16, of the container body 12. Thereby, the heat transfer pipe 17 and the heater 18 eliminate a need to extend through the heat storing material filling part of the container body 12. This constitution prevents leakage of the molten heat storing material 16 from a through-part U to the external part of the container body 12.

摘要： PROBLEM TO BE SOLVED: To accurately determine the lifetime of an arc-extinguishing bar and carry out its replacement at a proper replacement period of time. SOLUTION: An arc-extinguishing bar 20 is mounted at the tip of a movable electrode 18, thereby making it feasible to extinguish a slit arc generated between the movable electrode 18 and a fixed electrode 8 in cooperation with the arc-extinguishing bar 20 and an arc-extinguishing cylinder 13. A deterioration display cylinder 22 inserted through a connection screw 21 is received in the base end surface of the arc- extinguishing bar 20. The deterioration display cylinder 22 is colored reddish brown which is different from the arc-extinguishing bar colored white. When the movable electrode 18 is pulled out from the fixed electrode 8, an arc is generated between the tip of the fixed electrode 8 and the tip of the movable electrode 18, and the arc is also discharged into the arc-extinguishing bar. When the opening operation of the movable electrode 18 is repeated, the outer circumferential surface of the arc- extinguishing bar 20 is consumed in the direction of the center of the arc-extinguishing bar, namely, toward the deterioration displaying cylinder 22. When the base end of the white-colored arc-extinguishing bar is lost, the reddish brown-colored deterioration display cylinder 22 appears, so that the deterioration of the arc-extinguishing bar may be decided on the basis of a color difference.

摘要： PROBLEM TO BE SOLVED: To provide a fixing structure of a terminal cover support member capable of improving efficiency of a work for attaching the support member. SOLUTION: An engagement structure 41 for fixing a terminal cover support member 14 to a terminal portion 32 disposed on an electrical wire connecting side of an electrically conductive bar 13 is provided so as to engage the support member 14 with the engagement structure 41. Therefore, the support member 14 is engaged with the terminal portion 32 by inserting the support member 14 into the terminal portion 32 and pushing the support member 14 on the side of an electrically conductive portion 31. Accordingly, the support member 14 can be easily attached to the terminal portion 32 of the conductive bar 13, and can improve efficiency of an assembling work of a bushing 10. The number of man-hours of the work for attaching the support member 14 to the conductive bar 13 can be reduced because a work for bolt fastening or pin clasping etc. is not required.

摘要： PROBLEM TO BE SOLVED: To provide a bursting structure for a switch capable of suppressing an infiltration of foreign substances such as rain or dust into a body case after pressure is released. SOLUTION: A pressure-release lid 21 is turnably supported in upwardly opening direction to the outer surface of the sidewall of a body case 12, and that pressure-release lid 21 is always biased in a direction in which a pressure- release hole 14 is closed by elastic force of a helical torsion spring 32. The pressure-release hole 14 is held in a position where the pressure-release hole 14 is closed through the engagement of a latched member 34 with a latching member 15. When internal pressure is increased, the engagement of the latched member 34 with the latching member 15 is released, and the pressure-release lid 21 turns in the upwardly opening direction against the elastic force of the helical torsion spring 32. As a result, the pressure-release hole 14 is opened, and thus the internal pressure of the body case 12 is released. After the pressure is released, the pressure-release lid 21 is actively turned, in a direction in which the pressure-release hole is closed by the elastic force of the helical torsion spring 32. This turning is limited by contact of the latched member 34 with the latching member 15. COPYRIGHT: (C)2003,JPO
