JP 2010-92801 A

  In general, a plurality of (for example, three) high-voltage cutouts 100 are provided in the power distribution facility 2 such as a brace fixed to the utility pole 1. Therefore, when the charging terminals 111a and 111b of the cut-out connection instrument 110 are inserted into and extracted from the insertion ports 106a and 107a of the connection terminals 106 and 107 of the high-voltage cut-out 100, the charging terminals 111a and 111a, Care must be taken so that 111b does not interfere with the electric wires, power distribution facility 2, etc., and the work is complicated.

  Then, this invention makes it a subject to provide the cutout connection instrument which enabled it to operate insertion / extraction easily in the insertion port of each connection terminal of a high voltage | pressure cutout. .

  The cut-out connecting device according to the present invention includes a box-shaped container body having an opening, a pair of connection terminals disposed in the container body and having an insertion port, and a cover for opening and closing the opening of the container body. And a fuse set on the inner surface of the cover, and a pair of contact blades protruding from the fuse toward the inner side of the container body and inserted into and removed from the insertion port of each connection terminal. A cut-out connection device that is used by opening a cover with respect to a high-pressure cut-out, wherein the conductive first base and the second base are arranged in a straight line so as to face each of the connection terminals. The first and second charging terminals that are bendable and electrically coupled in a direction away from the first and second connecting terminals from which the contact blades are removed and the insertion terminals of the other connecting terminals are inserted and removed. An electrical terminal and the first base Projecting into the second base is characterized by the connector for connecting the front end portion of the operating member is provided in the first base or the second base.

  According to this cutout connecting device, the first base terminal and the second base terminal project from the first base and the second base, respectively, and the first base and the second substrate are bent. By changing the direction from the state to the straight state, the direction is changed from the open state to the parallel state. And this cutout connection instrument pushes up the insulation operating rod connected to the operating tool in a state where either the first base or the second base is bent so as to be separated from one of the connection terminals. Thus, it can be brought close to the high-pressure cut-out with the cover opened.

  Then, by further pushing up one base provided with the connecting tool to which the operating tool connected with the insulating control rod is connected toward one connection terminal, the electric charging terminal protruding from the one base is Insert it into the connection terminal insertion port. At this time, since the other base is in a bent state, the power application terminal projecting from the other base is not inserted into the insertion port of the other connection terminal.

  After that, the operator removes the insulating operation rod from the operation tool, pushes it against the other base, and pushes it up so that the other base is in a straight line with the one base, and the charging terminal protruding from the other base Is inserted into the insertion port of the other connection terminal. In this way, this cut-out connection device has the first base and the second base separately placed close to each connection terminal, so that each charging terminal can be easily inserted into the insertion port of each connection terminal. It has become.

  In the cutout connecting device according to the present invention, it is preferable that the first base and the second base are connected by a hinge and connected by a lead wire.

  According to this cutout connecting device, the first base and the second base are connected by the hinge, so that the connection strength between the first base and the second base can be sufficiently secured. In the hinge, the first base and the second base may not be reliably electrically connected, but the electrical connection between the first base and the second base is ensured by the lead wire. be able to.

  Further, in the cutout connecting device according to the present invention, it is preferable that the coupling tool is provided with a distal end side connecting the distal end portion of the operation tool deflected outward.

  According to this cut-out connecting device, the distal end side of the connecting tool that connects the distal end portion of the operating tool is provided to be deflected outward, whereby the operating tool connected to the connecting tool and the operating tool are connected. With respect to the direction of the insulating operation rod, it is possible to deflect the direction of the power application terminal protruding from the base provided with the coupler. Therefore, even if the high-voltage cutout is installed in the power distribution facility in an inclined position and the connection terminals are inclined, the insulation operation rod is directed vertically, and the lower end side of the insulation operation rod fixes the power distribution facility. It can be prevented from interfering with the utility pole.

  Further, in the cutout connecting device according to the present invention, the first base or the second base is longer than the second base or the first base, and the connector is provided on the base formed short. It is preferable that

  According to this cut-out connection device, one base is formed longer than the other base, and the base formed by another insulating operation rod is pushed by providing a connector on the base formed short. The charging terminal projecting from the long formed base moves so as to draw an arc with the boundary between the long formed base and the short formed base as the center of rotation.

  However, since the charging terminal projecting on the base pushed by another insulation operation rod moves in a circular arc with the distance from the power-supplying terminal to the boundary between the base and the base as a radius, one base is By being formed longer than the other base, it moves along a large arc, more specifically, a linear trajectory. Therefore, when the base pushed by the insulating operation rod is formed longer than the other base, this power-applying terminal moves linearly and can be inserted deep into the insertion opening of the connection terminal.

  Further, in the cutout connecting device according to the present invention, the first base or the second base protrudes toward the second base or the first base, and supports the bases so as not to bend too much. It is preferable that the stopper is fixed.

  According to this cutout connecting device, even if the cutout connecting device is in an inclined posture, the stopper fixed to one base supports the other base, so that the other base not connected to the insulating operation rod hangs down. It will be in the state which does not fall, and can make it easy to push up the other base | substrate with an insulation operating rod.

FIG. It is a front view which shows the state just before connecting the cutout connection tool which concerns on this invention to a high voltage | pressure cutout. It is a front view which shows the state in the middle of connecting the cutout connection tool which concerns on this invention to a high voltage | pressure cutout. It is a front view which shows the state after connecting the cutout connection tool which concerns on this invention to a high voltage | pressure cutout. An example of a high-pressure cutout is shown, (a) is a front view showing a state where the cover is closed, (b) is a front view showing a state where the cover is opened, and (c) shows a state where the cover is opened. It is a perspective view. It is a front view which shows the state by which the conventional cutout connection tool was connected to the high voltage | pressure cutout.

  An embodiment of a cutout connecting device according to the present invention will be described with reference to FIGS. 1 to 4. In the following description, the same parts as those in the related art are basically denoted by the same reference numerals.

  The cutout connecting device is a conductive first arranged in a linear state as shown in FIG. 1B in a state facing the primary side connecting terminal 106 and the secondary side connecting terminal 107 of the high voltage cutout 100. The base 10 and the second base 20 are bendable and electrically connected as shown in FIG. 1A, and the first power-supplying terminal 11 is connected to the first base 10 and the second base 20, respectively. And the 2nd voltage-applying terminal 21 is protrudingly provided.

  The first base 10 and the second base 20 are fixed to the bases 10 and 20 from a straight state by fixing the wings 41 and 41 of the hinge 40 to the lower surface on which the respective charging terminals 11 and 21 are not projected. Can be bent in the direction in which the lower surfaces of the two are overlapped with each other (in the drawing, the shape of “he”).

  However, the base of the stopper 30 is fixed to the lower surface of the second base 20 so that the first base 10 and the second base 20 are not bent too much (shown only in FIG. 1). The distal end side of the stopper 30 protrudes toward the lower surface of the first base 10 and supports the bent lower surface of the first base 10. The stopper 30 may be configured such that the base is fixed to the lower surface of the first base 10 and the tip side of the stopper 30 supports the lower surface of the second base 20.

  Furthermore, the first base 10 and the second base 20 are connected by the lead wire 31 because the electrical connection may be uncertain by being connected by the hinge 40 (see FIG. 1). Only shown). Each end portion of the lead wire 31 may be fixed to the back surface or the side surface of the bases 10 and 20, or the wing portions 41 and 41 are fixed if the hinge 40 has conductivity. You may fix to a screw.

  The first base 10 is longer than the second base 20, in other words, the second base 20 is shorter than the first base 10. Since the first base 10 and the second base 20 are connected to a hinge 40 so as to be bent, the first power supply terminal 11 projecting from the first base 10 is connected to the first base 10. The boundary moves between the center of rotation 10 and the second base 20 as a rotation center, and moves in a circular arc with a distance (hereinafter referred to as “radius”) from the rotation center to the first power application terminal 11.

  By making the first base 10 longer than the second base 20, the radius becomes longer than when the first base 10 and the second base 20 have the same length. When the radius is short, the first voltage application terminal 11 moves while drawing a small arc. When the radius is long, the first voltage application terminal 11 moves while drawing a large arc. It can be moved along a locus close to a straight line.

  On the back surface of the second base 20, there is provided a conductive connector 60 that connects a rod-shaped operation tool 50 having a twist lock portion at the base end (lower end in the drawing). The coupling tool 60 is formed in an arc shape by deflecting the distal end side (lower end side in the drawing) connecting the distal end portion (upper end portion in the drawing) of the operation tool 50 outward (in the direction opposite to the first base plate 10). Has been.

  By doing so, the direction of the second power application terminal 21 can be deflected with respect to the direction of the rod-shaped operation tool 50 connected to the connection tool 60 and the insulating operation bar 120 connected to the operation tool 50. . That is, even if the second base 20 is inclined parallel to the secondary side connection terminal 107, the insulation operation rod 120 and the operation tool 50 are directed downward, that is, in a substantially vertical posture.

  This cutout connecting device is configured as described above, and next, a method of use will be described.

  Prior to using this cut-out connecting device, as shown in FIGS. 5B and 5C, the cover 102 of the high-voltage cut-out 100 in the inclined posture is opened, and the contact blades 104 and 105 protruding from the fuse 103 are provided. It is assumed that the primary side connection terminal 106 in the container body 101 is removed from the insertion port 106 a and the secondary side connection terminal 107 from the insertion port 107 a.

  Then, as shown in FIG. 2, the operator lifts the insulating operation rod 120 connected to the operation tool 50 of the cut-out connection tool, and the second power application terminal 21 is inserted into the insertion port 107 a of the secondary connection terminal 107. To face each other. At this time, the second base 20 is substantially parallel to the insertion port 107a of the secondary side connection terminal 107 in the inclined posture, while the first base 10 is bent by its own weight, and the primary side connection terminal 106 is bent. It is not parallel to. However, as shown in FIG. 1A, the first base 10 is supported by the stopper 30 and has a substantially horizontal posture without being directed downward.

  Then, as shown in FIG. 3, the operator further lifts the insulating operation rod 120, whereby the second power application terminal 21 is inserted into the insertion port 107 a of the secondary side connection terminal 107. At this time, the first voltage application terminal 11 is being inserted into the insertion port 106 a of the primary side connection terminal 106. However, the direction of the first power application terminal 11 does not coincide with the direction of the insertion port 106 a of the primary side connection terminal 106. In addition, since the insulation operating rod 120 is connected outward with respect to the 2nd base | substrate 20 with the coupling tool 60, and has faced the substantially vertical attitude | position, it does not interfere with the utility pole 1 (refer FIG. 6).

  Then, as shown in FIG. 4, the operator removes the insulation operation rod 120 from the twist lock portion of the operation tool 50, pushes the insulation operation rod 120 against the back surface of the first base 10, The charging terminal 11 is inserted into the insertion port 106 a of the primary side connection terminal 106. Since the first base 10 is formed longer than the second base 20, and the first power application terminal 11 moves along a locus close to a straight line with a large radius, the first base terminal 10 is inserted into the insertion port 106a of the primary side connection terminal 106. Is inserted into the back.

  In this way, when the first voltage application terminal 11 and the second voltage application terminal 21 are inserted into the insertion port 106a of the primary side connection terminal 106 and the insertion port 107a of the secondary side connection terminal 107, insulation is achieved. The operation rod 120 is moved away from the back surface of the first base 10. Then, a high voltage is applied to the first and second power application terminals 11 and 21 by the wiring system 51 led out from the operation tool 50. And if the electric current which flows when there is a cause of the ground fault in the electric line is detected by the CT sensor (not shown), the detection result is notified to the notification means (not shown).

  After the work is completed, the insulation operation rod 120 is connected to the twist lock portion of the operation tool 50, and the insulation operation rod 120 is pulled down. Then, the first voltage application terminal 11 and the second voltage application terminal 21 come out of the insertion port 106 a of the primary side connection terminal 106 and the insertion port 107 a of the secondary side connection terminal 107. Also at this time, the insulating operation rod 120 does not interfere with the utility pole 1.

  The present invention can be variously modified without being limited to the above embodiment. For example, the connector 60 may be provided on the first base 10 or may be provided perpendicular to the second base 20 or the back surface of the first base 10 without being deflected.

  In addition, the first base 10 and the second base 20 may be provided with the same length, and are connected not by a hinge 40 in a narrow sense but by a plate material that can be bent repeatedly without being cut at the center line. May be. Further, the lead wire 31 and the stopper 30 may not be provided depending on the use situation.
