=== Inundation amount information ===
Hereinafter, with reference to FIG. 10, the inundation amount information in the present embodiment will be described. FIG. 10 is a diagram showing the inundation amount information in the present embodiment. The temperature rise width indicates a temperature difference between the switch 5 and the other switch before and after heating the switch 5 and the other switches for the heating time by using the planar heater 137 of the detector 1. That is, for example, the temperature rise width of the switch 5 includes the temperature of the switch 5 before heating the switch 5 for the heating time using the planar heater 137 and the switch for the heating time using the planar heater 137. The difference with the temperature of the switch 5 after heating 5 is shown. The temperature of the switch 5 is detected by a temperature sensor 138.

  The inundation amount information D1 and D2 is stored in the storage unit 15 of the detector 1. For example, the storage unit 15 may store other inundation amount information other than the inundation amount information D1 and D2. The inundation amount information D1 and D2 may be created based on, for example, an experiment, or may be created by simulation or the like.

  The inundation amount information D1 indicates the relationship between the temperature rise width of the switch 5 when the switch 5 is heated for the heating time and the inundation amount water level with respect to the temperature rise width of the switch 5. The water immersion amount information D1 may indicate the relationship between the temperature rise width of the switch 5 and the water immersion amount of the switch 5 with respect to the temperature rise width.

  The inundation amount information D2 is the same information as the inundation amount information D1, and the amount of water immersion with respect to the temperature rise width of other switches when the other switches are heated for the heating time and the temperature rise width of other switches. It shows the relationship with the water level. The water immersion amount information D2 may indicate the relationship between the temperature rise width of other switches and the amount of water immersion of other switches with respect to the temperature rise width. The other switches are switches whose specifications are different from those of the switch 5.

  For example, the switch 5 and other switches are provided with the same amount of heat (heated) when the amount of water immersion is the same because the materials and sizes of the casings of the switch 5 and other switches are different. When the temperature rise is different. For example, the water immersion amount information D1 and D2 indicate that when the temperature rise width is T1, the water immersion amount is W1 for the switch 5, and the water immersion amount is W2 for the other switches.

  For example, when estimating the amount of inundation of the switch 5, in order to improve the estimation accuracy of the amount of inundation, the switch 5 is based on the inundation amount information D1 corresponding to the switch 5 of the inundation amount information D1 and D2. It is necessary to estimate the amount of inundation.

=== Seal ===
Hereinafter, the seal in the present embodiment will be described with reference to FIG. FIG. 11 is a view showing a seal affixed to the switch according to the present embodiment.

  The seal 8 is used to identify the switch 5. The seal 8 further indicates the mounting position of the detector 1. The outer shape of the seal 8 has a substantially rectangular shape. The color of the seal 8 is different from the color of the bottom surface 51 of the switch 5. The seal 8 has a barcode 82 and an exposed opening 83.

  The exposure opening 83 is an opening for exposing the mounting position on the bottom surface 51 of the switch 5 from the seal 8. The attachment position is a position where the detector 1 is to be attached on the bottom surface 51. For example, when the inundation amount information D1 is created based on an experiment using the detector 1, the attachment position is a predetermined position of the switch 5 to which the detector 1 is attached when the inundation amount information D1 is created. It may be there.

  The exposure opening 83 has a substantially rectangular shape, for example. With the exposed opening 83, the seal 8 has a ring shape surrounding the periphery of the mounting position. Furthermore, the exposure opening 83 has a shape corresponding to the outer shape of the detector 1, for example.

  The bar code 82 indicates identification information for identifying the switch 5. The bar code 82 is provided on one edge of the four edges of the seal 8 on the + X side. The four edge portions are, for example, two edge portions whose longitudinal direction is along the X axis and adjacent in the Y axis, and two edge portions whose longitudinal direction is along the Y axis and adjacent in the X axis. Is shown. The barcode 82 is provided at a position where the reader 71 can read the identification information of the barcode 82 when the detector 1 is attached to the attachment position. For example, when the detector 1 is attached at a position other than the attachment position, the reading device 71 cannot read the identification information of the barcode 82.

=== Reading identification information ===
Hereinafter, reading of identification information in the present embodiment will be described with reference to FIGS. 12 and 13. FIG. 12 is a diagram showing the detector and the switch in a state where the identification information can be read in the present embodiment. FIG. 13 is a diagram showing the detector and the switch in a state where identification information cannot be read in the present embodiment. In FIGS. 12 and 13, the reading device 71 is not visible, but is shown by a broken line for convenience of explanation.

<When reading is possible>
For example, when the detector 1 is attached to the bottom surface 51 so that the −Z side in the outer shape of the detector 1 is along the periphery of the exposure hole 83, the reading device 71 can read the identification information indicated by the barcode 82. Faces the barcode 82 (FIG. 12). In this case, since the switch to be estimated by the detector 1 can be identified, the amount of flooding by the detector 1 can be estimated. The position where this identification information can be read corresponds to the mounting position.

<When reading is not possible>
For example, when the position of the detector 1 is shifted (FIG. 13), the reader 71 cannot read the identification information of the barcode 82. In this case, since the switch to be estimated by the detector 1 cannot be identified, the amount of water immersion by the detector 1 cannot be estimated.

  From the above, for example, based on the fact that the detector 1 can estimate the amount of water immersion only when the detector 1 is attached to the attachment position, it is determined whether or not the detector 1 is attached to the attachment position. be able to.

=== Processing Unit ===
Hereinafter, the processing unit in the present embodiment will be described with reference to FIGS. 3 and 10.

  The processing unit 14 of the detector 1 estimates the amount of water immersion of the switch to which the detector 1 is attached.

  The processing unit 14 selects the inundation amount information corresponding to the switch to be estimated based on the identification information read by the reading device 71. Thereafter, the processing unit 14 estimates the amount of water immersion based on the selected water immersion amount information and the detection result of the temperature sensor 138.

  For example, the identification information read by the reading device 71 indicates the switch 5, and the processing unit 14 in the case where the temperature rise width when the switch 5 is heated for the heating time using the planar heater 137 is T1. Will be described.

  The processing unit 14 selects the inundation amount information D1 of the switch 5 as the switch to be estimated. Thereafter, the processing unit 14 operates the planar heater 137 for the heating time. Based on the detection result of the temperature sensor 138, the processing unit 14 detects the temperature increase width as T1. The processing unit 14 determines (estimates) the inundation amount water level W1 corresponding to the temperature increase width T1 in the inundation amount information D1 as the inundation amount of the switch 5.

=== Operation of the detector ===
Hereinafter, the operation of the detector in the present embodiment will be described with reference to FIGS. 1, 10, and 12.

  The detector 1 is attached to an attachment position on the bottom surface 51 of the switch 5 with the seal 8 as a mark. For example, the detector 1 is attached so as to be in the state of FIG. If the detector 1 is not attached so as to be in the state of FIG. 12, the detector 1 cannot estimate the amount of water immersion, and the detector 1 outputs an error signal indicating that the detector 1 is not attached at the attachment position. It is good to do. When the error signal is output, the detector 1 is attached again.

  The operation of estimating the amount of water immersion by the detector 1 may be started after the heating time is set by the timer setting button 233 of the remote controller 2, for example.

  After the detector 1 is attached to the attachment position, the detector 1 reads the identification information of the barcode 82. The detector 1 selects the inundation amount information D1 of the switch 5 as a switch to be estimated. Thereafter, the detector 1 operates the planar heater 137 for the heating time. Based on the detection result of the temperature sensor 138, the detector 1 detects the temperature rise width as T1, for example. The detector 1 determines (estimates) the water level W1 corresponding to the temperature rise width T1 in the water level information D1 as the water level of the switch 5.

[Second Embodiment]
=== Seal ===
Hereinafter, the seal in the present embodiment will be described with reference to FIG. FIG. 14 is a view showing a seal affixed to the switch according to the present embodiment. The same components as those in FIG. 11 are denoted by the same reference numerals, and the description thereof is omitted.

  The seal 9 is a seal having a configuration similar to that of the seal 8 (FIG. 11).

  The seal 9 has barcodes 92A, 92B, 92C, and 92D. Bar codes 92A, 92B, 92C, and 92D indicate identification information for identifying the switch 5 respectively. Bar codes 92A, 92B, 92C, and 92D are provided on each of the four edges of the seal 9. With these configurations, for example, even when the attachment position of the detector 1 with respect to the switch 5 is shifted by 90 degrees, it is possible to estimate the amount of water immersion of the switch 5. Accordingly, since the detector 1 can be attached to the switch 5 relatively easily, the usability of the detector 1 can be improved.

  As described above, the detector 1 is a device that estimates the amount of water intrusion in the switch 5 to which identification information for identifying each one is attached and one of the other switches. In the storage unit 15 of the detector 1, for example, inundation amount information D1 and D2 are stored. The water immersion amount information D1 indicates the relationship between the temperature rise width of the switch 5 when the switch 5 is heated for the heating time and the water immersion amount of the switch 5 corresponding to the temperature rise width of the switch 5. The inundation amount information D2 indicates the relationship between the temperature rise width of the other switch when the other switch is heated for the heating time and the inundation amount of the other switch corresponding to the temperature rise width of the other switch. Show. The reading device 71 reads identification information attached to the switch 5 and other switches. The processing unit 14 reads the identification information by the reading device 71, for example, the temperature rise width of the switch 5 when the switch 5 is heated for the heating time, and the inundation amount information D1 and D2 stored in the storage unit 15. The inundation amount of the switch 5 is estimated based on the inundation amount information D1 corresponding to the switch 5 whose identification information is read by the reading device 71. The detector 1 is attached to the surface to which the identification information in the switch 5 is attached. Therefore, the detector 1 is attached to the attachment position in the switch 5. Furthermore, the detector 1 can estimate the inundation amount based on the inundation amount information D1 corresponding to, for example, the switch 5 to be estimated. Therefore, the estimation accuracy of the amount of water immersion of the switch 5 can be improved.

  The identification information is written on a seal 8 attached to the switch 5. Therefore, identification information can be reliably attached to a position corresponding to the mounting position in the switch 5. Further, it becomes relatively easy to attach identification information to the switch 5. Moreover, the estimated accuracy of the amount of water immersion of the switch 5 can be improved by attaching the detector 1 to an attachment position reliably.

  The detector 1 is provided with a reading device 71. The identification information is written on the sticker 8 as a barcode 82. The seal 8 is affixed at a position corresponding to an attachment position where the detector 1 in the switch 5 is to be attached. The detector 1 is attached to the switch 5 with the seal 8 as a mark so that the reader 71 can read the identification information facing the barcode 82. For example, since an IC chip or the like in which identification information is stored becomes unnecessary, the cost for estimating the amount of water immersion of the switch 5 can be reduced. For example, it can be determined whether or not the detector 1 is attached to the attachment position based on whether or not the reading device 71 can read the identification information. And the estimated accuracy of the amount of water immersion of the switch 5 can be improved by attaching the reader 71 reliably to an attachment position.

  The color of the seal 8 is different from the color of the switch 5. When the seal 8 is affixed to the switch 5, the seal 8 has an annular shape surrounding the periphery of the mounting position. The detector 1 is mounted at a mounting position surrounded by the seal 8. The seal 8 attached to the switch 5 is made conspicuous, and the work efficiency of the work of attaching the detector 1 to the switch 5 using the seal 8 as a mark can be improved. Further, by preventing the detector 1 from being erroneously attached to a surface other than the surface to which the identification information is attached in the switch 5, it is possible to improve the estimation accuracy of the amount of water immersion of the switch 5. .

  The inner shape (exposed opening 83) of the seal 8 has a shape corresponding to the outer shape of the detector 1, and the detector 1 is attached so that the outer shape of the detector 1 follows the inner shape of the seal 8. . Therefore, since the detector 1 can be reliably attached to the attachment position, the estimation accuracy of the amount of water immersion of the switch 5 can be improved.

  The identification information is attached to the bottom surface 51 of the switch 5. Here, for example, in the case where the thickness of the casing in the switch 5 is the same on the entire surface including the bottom surface 51, the submerged water is uniformly stored in the bottom surface 51 inside the casing of the switch 5. The bottom surface 51 of the entire surface of the switch 5 has the maximum amount of change in the temperature rise with respect to the constant amount of water immersion when heated for the heating time. That is, for example, regarding the inclination of the water immersion amount information D1 in FIG. 10, the inclination of the water immersion amount information D1 on the bottom surface 51 of the entire surface of the switch 5 is the steepest inclination. Therefore, for example, when there is a certain error in the temperature rise width when heating is performed for the heating time, the estimation error of the flooding amount of the switch 5 based on the temperature rise width error is reduced by setting the bottom surface 51 as the mounting position. can do. Therefore, it is possible to improve the estimation accuracy of the amount of water immersion of the switch 5.

  In addition, 1st and 2nd embodiment is for making an understanding of this invention easy, and is not for limiting and interpreting this invention. The present invention can be changed and improved without departing from the gist thereof, and the present invention includes equivalents thereof.

  In addition, although 1st Embodiment demonstrated that the detector 1 estimated the amount of water immersion of the switch 5 as an electric power apparatus, it is not limited to this. For example, the detector 1 may estimate the amount of inundation of a power device having a housing such as a pole transformer.

  Moreover, although 1st Embodiment demonstrated that the seal | sticker 8 was affixed on the bottom face 51 of the switch 5, it is not limited to this. For example, the seal 8 may be attached to the side surface of the switch 5 or the like.

  In the first embodiment, the barcode 82 is described on the seal 8. However, the present invention is not limited to this. For example, the bar code 82 may be directly written on the bottom surface 51 of the switch 5.

  In the first embodiment, the identification information is described as the barcode 82. However, the present invention is not limited to this. For example, an IC tag that stores identification information and can perform near field communication may be provided on the bottom surface 51. In this case, the reading device 71 may read the identification information stored in the IC tag.
