A resistance value deriving means 53 for deriving a resistance value of the switch 9, and a construction connected to the primary side mounting portion 2 and the secondary side mounting portion 3 based on the resistance value derived by the resistance value deriving means 53. and a determination means 54 for determining whether the switch 9 is on. As described above, in the detection unit 5 according to the present embodiment, the resistance value derivation means 53 measures the resistance value of the construction switch 9 connected to the primary cable and the secondary cable 91. It is configured.

The primary side connector 50 and the secondary side connector 51 can be attached to and detached from the primary side attachment portion 2 and the secondary side attachment portion 3, respectively (that is, the detection portion 5 can be attached to the primary side attachment portion 2 and the secondary side attachment portion). 3), or may be provided integrally with the primary side mounting portion 2 and the secondary side mounting portion 3. When the primary side connector 50 and the secondary side connector 51 are detachable from the primary side mounting portion 2 and the secondary side mounting portion 3, respectively, the primary side connector 50 and the secondary side connector The end of 51 may be provided with a clamp, a crocodile grip, or the like.

When the switch is not connected to the primary side mounting portion 2 and the secondary side mounting portion 3, or when the switch in the OFF state is connected to the primary side mounting portion 2 and the secondary side mounting portion 3, With the primary side connector 50 connected to the primary side mounting portion 2 and the secondary side connector 51 connected to the secondary side mounting portion 3, the power source 52 is connected to either the primary side connector 50 or the secondary side connector 51. When a current is applied to either one (in this embodiment, the primary side connector 50), the current applied from the power supply 52 to the primary side connector 50 does not flow through the secondary side connector 51, so the resistance value is derived. The resistance value measured by means 53 becomes infinite.

On the other hand, when the switch in the ON state is connected to the primary side mounting portion 2 and the secondary side mounting portion 3, the primary side connector 50 is connected to the primary side mounting portion 2, and the secondary side mounting portion 3 When a current is applied from the power source 52 to the primary side connector 50 with the secondary side connector 51 connected to the , the current applied from the power source 52 to the primary side connector 50 flows through the secondary side connector 51, so the resistance The resistance value measured by the value deriving means 53 will drop from infinity.

A reference resistance value is set in the discrimination means 54 for discriminating that the work switch 9 is in the on state, and the resistance value measured by the resistance value deriving means 53 is equal to or less than the reference resistance value. In some cases, it is configured to determine that the construction switch 9 is in the ON state. The determining means 54 determines the state in which the construction switch 9 is in the ON state (the energized state in which the current flows through the primary side mounting portion 2 and the secondary side mounting portion 3 via the construction switch 9). ) and a state in which the construction switch 9 is off (a non-energized state in which no current flows from the primary side mounting portion 2 to the secondary side mounting portion 3).

The detection unit 5 has switching means for switching between a state in which the resistance value measurement function is exhibited and a state in which the resistance value measurement function is not exhibited, and the resistance value measurement function is exhibited by the switching means. When a current is applied from the power supply 52 to the primary side connector 50, the resistance value can be measured by the resistance value derivation means 53, and the determination means 54 is configured to switch to a state in which the ON state of the work switch 9 can be determined. may be

The notification unit 6 is configured to notify that the work switch 9 is on when the determining means 54 determines that the work switch 9 is on. Note that the notification unit 6 may be configured to notify that the work switch 9 is on by sound (auditory notification) or display (visual notification). Further, the notification unit 6 may be configured as one device together with the detection unit 5 or may be configured as a device separate from the detection unit 5 .

The configuration of the temporary cable holder 1 according to this embodiment is as described above. Next, how to use the temporary cable holder 1 according to this embodiment will be described.

When the temporary cable holder 1 is used, the primary side attachment portion 2 and the secondary side attachment portion 3 are attached to the utility pole P as shown in FIGS. More specifically, the primary side fixing portion 21 is fixed to the utility pole P, and the secondary side fixing portion 31 is fixed to the utility pole P. As shown in FIG. In addition, in the present embodiment, the mounting position of the primary side mounting portion 2 and the mounting position of the secondary side mounting portion 3 are shifted in the axial direction of the utility pole P. 2 and the mounting position of the secondary side mounting portion 3 are shifted. Then, the detection unit 5 and the notification unit 6 are also attached to the utility pole P to exhibit the resistance value measurement function.

After moving the construction switch 9 to the place of use, the three primary cables 90 are attached to the primary conductive part 20 and the three secondary cables 91 are attached to the secondary conductive part 30 . As a result, the primary side cable 90 and the secondary side cable 91 are placed temporarily.

If the switch is turned off when the primary cable 90 and the secondary cable 91 are temporarily placed, the current sent from the power supply 52 to the primary side mounting portion 2 is not transmitted to the secondary side mounting portion 3. Therefore, the resistance value between the primary side mounting portion 2 and the secondary side mounting portion 3 derived by the resistance value deriving means 53 becomes infinite.

In this case, since the resistance value derived by the resistance value deriving means 53 exceeds the reference resistance value, it is not determined by the determination means 54 that the construction switch 9 is in the ON state, There is also no notification that the device 9 is on.

On the other hand, if the switch is switched on when the primary cable 90 and the secondary cable 91 are temporarily placed, the current sent from the power supply 52 to the primary side mounting portion 2 will flow through the switch to the secondary side. Since it is transmitted to the side mounting portion 3, the resistance value between the primary side mounting portion 2 and the secondary side mounting portion 3 derived by the resistance value deriving means 53 decreases from infinity.

If the resistance value derived by the resistance value deriving means 53 is equal to or less than the reference resistance value, the discrimination means 54 discriminates that the construction switch 9 is in the ON state, and the notification section 6 turns off the construction switch 9. It is notified that it is on.

In this manner, the temporary cable storage tool 1 determines whether the work switch 9 is on or off depending on whether or not the notification unit 6 notifies when the primary cable 90 and the secondary cable 91 are temporarily placed. It is possible to grasp whether it is in the state.

As described above, according to the temporary cable holder 1 according to the present embodiment, the primary side mounting portion 2 for mounting the primary side cable 90 and the secondary side mounting portion 3 for mounting the secondary side cable 91 are provided. is connected via the detection unit 5 , the primary cable 90 is connected to the primary mounting unit 2 and the secondary cable 90 is connected to the secondary mounting unit 3 while the construction switch 9 is switched to the OFF state. When the secondary cable 91 is connected, the current applied to one of the primary side mounting portion 2 and the secondary side mounting portion 3 is not transmitted to the other of the primary side mounting portion 2 and the secondary side mounting portion 3. A state in which the side mounting portion 2 and the secondary side mounting portion 3 are not energized, that is, the resistance value of the construction switch 9 is infinite (a state in which the resistance value of the construction switch 9 exceeds the reference resistance value). ) state, and the notification unit 6 does not perform notification, it is possible to grasp that the construction switch 9 temporarily placing the primary side cable 90 and the secondary side cable 91 is in the OFF state.

On the other hand, when the primary side cable 90 is connected to the primary side mounting portion 2 and the secondary side cable 91 is connected to the secondary side mounting portion 3 in a state where the work switch 9 is switched to the on state, the primary side Since the current applied to the side mounting portion 2 is transmitted to the secondary side mounting portion 3 through the construction switch 9 (primary side cable 90, secondary side cable 91), the detection portion 5 is in the energized state, that is, the construction When the resistance value of the switch 9 drops from infinity to less than the reference resistance value, and the notification unit 6 recognizes the notification that the switch 9 for construction work is on, the primary cable 90 and the secondary cable 90 are turned on. It can be grasped that the construction switch 9 in which the secondary cable 91 is temporarily placed is in the ON state.

Therefore, the temporary cable storage device 1 can detect and notify the ON state of the construction switch 9, thereby preventing the construction switch 9 from being connected to the power distribution equipment in the ON state. be able to.

Further, since the temporary cable storage device 1 according to the present embodiment is configured to be able to determine that the work switch 9 is in the ON state based on the resistance value of the work switch 9, It is possible to grasp whether the work switch 9 is on or off in a safe state where the power from the distribution equipment is not supplied to the work switch 9 .

Furthermore, in the temporary cable holder 1 of the present embodiment, since the primary-side conductive portion 20 has an elongated shape, the ends of the three primary-side cables 90 are arranged side by side at intervals in the longitudinal direction of the primary-side conductive portion 20. Therefore, it is possible to prevent the terminals of the three primary cables 90 from coming into contact with each other and the three primary cables 90 from being entangled, thereby facilitating the work of connecting the primary cables 90 to the power distribution equipment. be able to do it.

In addition, since the secondary-side conductive portion 30 also has an elongated shape, the terminals of the three secondary-side cables 91 can be arranged side by side with a gap in the longitudinal direction of the secondary-side conductive portion 30. It is possible to prevent the terminals of the side cables 91 from coming into contact with each other and the three secondary cables 91 from being entangled, thereby facilitating the work of connecting the secondary cables 91 to the power distribution equipment.

The primary-side conductive portion 20 and the secondary-side conductive portion 30 are fixed at positions in the circumferential direction about the axis of the utility pole P by the fixtures 4 (the primary-side fixing portion 21 and the secondary-side fixing portion 31). Since it can be changed, the arrangement of the primary side conductive portion 20 and the secondary side conductive portion 30 around the utility pole P can be determined according to the installation location (connection location) of the primary side cable 90 and the secondary side cable 91. Accordingly, it is possible to prevent the primary side conductive portion 20 and the secondary side conductive portion 30 from interfering with the work on the power distribution equipment.

Furthermore, the fixed positions of the primary-side conductive portion 20 and the secondary-side conductive portion 30 in the axial direction of the utility pole P can be changed by the fixtures 4 (the primary-side fixing portion 21 and the secondary-side fixing portion 31). , the primary-side conductive portion 20 and the secondary-side conductive portion 30 can be fixed to the utility pole P even when the primary-side conductive portion 20 and the secondary-side conductive portion 30 overlap when viewed from above. Therefore, by suppressing the arrangement space of the primary-side conductive portion 20 and the secondary-side conductive portion 30, it is possible to secure a large working space.

It should be noted that the temporary cable holder for construction switches of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the scope of the present invention.

Although the direction of the primary side conductive portion 20 and the secondary side conductive portion 30 is changed by changing the direction of the fixture 4 (primary side fixing portion 21, secondary side fixing portion 31) itself, the present invention is not limited to this configuration.
For example, the orientations of the primary conductive part 20 and the secondary conductive part 30 may be changed by changing the attachment positions of the primary conductive part 20 and the secondary conductive part 30 with respect to the fixture 4 .

Although the fixture 4 includes the primary side fixing part 21 and the secondary side fixing part 31, the primary side fixing part 21 and the secondary side fixing part 31 are configured to be attached to one fixture 4. good too.

Although the primary-side conductive portion 20 and the secondary-side conductive portion 30 are configured to extend outward in the radial direction of the utility pole P, the present invention is not limited to this configuration. For example, the primary-side conductive portion 20 and the secondary-side conductive portion 30 are arranged so as to have a twisted positional relationship with respect to the utility pole P in a direction that intersects the axial direction of the utility pole P. may
