By the way, business operators related to transformers include not only transformer manufacturers, but also manufacturers of cubicles that house transformers, contractors who install cubicles and transformers, and maintenance of transformers. There are multiple types of business operators, such as a maintenance business operator who performs maintenance and an operation business operator who operates the installed transformer. Therefore, when actually operating a transformer, the following problems arise.

That is, distribution of transformers is carried out, for example, in the following flow. Specifically, a transformer manufacturer delivers transformers to a cubicle manufacturer. Then, the cubicle manufacturer delivers the transformer and the cubicle to the contractor. Then, the contractor installs the transferred transformer and cubicle in the building, factory, or the like of the operator and delivers them. Then, the operator operates the delivered transformer and entrusts the maintenance to the maintenance operator. Further, in such a distribution form, the manufacturer that manufactures the transformer provides the operator with information on the transformer, such as the instruction manual of the transformer.

Due to the operation described above, information about transformers, such as instruction manuals, remains in the hands of operators, but it is difficult to reach maintenance operators who actually perform maintenance on transformers. It has become. Therefore, even if the maintenance company visits the site where the transformer to be maintained is installed, they cannot obtain information about the transformer. Excessive effort is required for maintenance, such as making inquiries.

Here, for example, based on the technology disclosed in Patent Document 1, it is conceivable to provide a code that encodes information about the transformer on the surface of the transformer. However, in the technique disclosed in Patent Document 1, a code is provided by stamping the surface of the transformer with a dot pin. Therefore, such a code may not be read by a code reader, and there is still a concern that information cannot be provided at the site where the transformer is installed.

In addition, the information coded in Patent Document 1 is information for the "traceability" of the transformer, that is, information that the "manufacturer" who manufactures the transformer refers to as necessary. It is not information that is referred to by the "operator" or "maintenance provider". Therefore, information for such traceability is usually provided in a portion not visible to the user. That is, Cited Document 1 merely suggests a technique of providing a cord in a portion that is not visible to the user. Even if the information is coded, it is only possible to obtain a configuration in which the code is provided in a portion that is not visible to the user. Therefore, even if the maintenance operator goes to the site where the transformer to be maintained is installed, it is difficult to notice the existence of the cord in the first place. Concerns about not being able to provide information remain.

Therefore, the present embodiment provides a configuration in which information on the transformer can be easily obtained at the site where the transformer is installed.

The transformer according to the present embodiment includes an inspection target portion that is checked by an inspection operator at the time of inspection, and an information code provided in the inspection target portion , and the inspection target portion is an oil level gauge. A part of the level gauge has a gauge surface that indicates the amount of oil, and the information code is provided on a portion of the oil level gauge that has the gauge surface. It is configured to contain the information code .

In this case, the oil level gauge 12 is attached with the gauge surface 12a facing the front side of the transformer 10 . The direction of the instrument surface 12a of the oil level gauge 12 can be changed as appropriate. For example, the instrument surface 12a may face the left or right side of the transformer 10. It can be directed to the rear side. Further, the instrument surface 12a may face the left front side, the right front side, or the like of the transformer 10, for example.

A part of the thermometer 13 has a gauge face 13a that indicates the temperature of the transformer 10 and its surroundings. In this case, the instrument surface 13a is provided in the shape of a circular window. Also, in this case, the thermometer 13 is attached with the instrument surface 13 a facing the front side of the transformer 10 . Note that the direction of the instrument surface 13a of the thermometer 13 can be changed as appropriate. For example, the instrument surface 13a may face the left side or the right side of the transformer 10. and may be facing backwards. Further, the instrument surface 13a may face the left front side, the right front side, or the like of the transformer 10, for example.

In this embodiment, the direction of the gauge surface 12a of the oil level gauge 12 and the direction of the gauge surface 13a of the thermometer 13 both face the front side of the transformer 10, that is, they face the same side. The direction of the instrument surface 12a of the oil level gauge 12 and the direction of the instrument surface 13a of the thermometer 13 may be the same or different.

In this embodiment, an information code 100 is provided on the oil level gauge 12, which is an example of an inspection target portion. In this case, the information code 100 is composed of a so-called sticker having adhesiveness, and is attached to the surface of the oil level gauge 12 . The information code 100 is attached to a portion of the oil level gauge 12 that has the gauge surface 12a, and more specifically, is attached to the upper portion of the gauge surface 12a. Therefore, an inspection operator standing in front of the transformer 10 can visually recognize the information code 100 together with the gauge surface 12 a of the oil level gauge 12 . Note that the information code 100 may be provided on the left, right, or bottom of the instrument panel 12a. That is, the information code 100 is preferably provided near the instrument surface 12a.

In this case, the information code 100 is provided as a QR code (registered trademark), and various information about the transformer 10, which is the object, is coded as transformer information. The transformer information coded in the information code 100 in this case includes at least the serial number of the transformer 10 which is the object. In addition, the transformer information coded in the information code 100 accesses a website configured so that the instruction manual of the transformer 10, the outline drawing of the transformer 10, and the test report of the transformer 10 can be downloaded. contains address information for

FIG. 3 shows a configuration example of a web page W that can be accessed by reading the information code 100 with a code reader (not shown). The web page W is provided with a specification display portion Wa indicating the specifications of the transformer 10, and an outline drawing button Wb, an instruction manual button Wc, and a test report button Wd that are operable. Then, by operating the outline drawing button Wb, the outline drawing of the transformer 10 can be downloaded, and by operating the instruction manual button Wc, the instruction manual of the transformer 10 can be downloaded, and the test result can be obtained. By operating the book button Wd, the test report of the transformer 10 can be downloaded.

The manufacturing number of the transformer 10 is a number set for each manufactured transformer 10 in the order in which it was manufactured. That is, since one manufacturing number is set for one transformer 10 , the manufacturing number of the transformer 10 is uniquely set for each transformer 10 .

According to the present embodiment described above, the transformer 10 is provided with the information code 100 in the inspection target portion, in this case, the oil level gauge 12, which is checked by the inspection operator at the time of inspection. Since the information code 100 is affixed to the inspection target portion of the transformer 10, a maintenance operator who goes to the site where the transformer 10 is installed can read the information code 100 using a code reader (not shown). Transformer information about the transformer 10 can be readily obtained by reading the . In addition, the transformer 10, which is the "thing", and the "information" obtained from the information code 100 correspond to each other.

In the present embodiment, the object to be inspected provided with the information code 100 is the oil level gauge 12 that can measure the amount of oil even when the power of the transformer 10 is turned off. On the other hand, the inspection work of the transformer 10 is normally performed with the power of the transformer 10 turned off. Therefore, according to the present embodiment, the information code 100 is attached to the oil level gauge 12 that can be measured even when the power of the transformer 10 is turned off, that is, the inspection object that is likely to be checked by the inspection operator during inspection. Since the information code 100 is provided, the inspector can easily notice the existence of the information code 100 and obtain the transformer information about the transformer 10 more easily.

Further, according to the present embodiment, the information code 100 is provided on a portion of the oil level gauge 12 having the gauge surface 12a. According to this configuration, the inspection operator can easily notice the existence of the information code 100 when checking the oil level gauge 12 during inspection, and can obtain the transformer information about the transformer 10 more easily. Further, the inspector can capture the image of the instrument surface 12a of the oil level gauge 12 to include the information code 100 in the image. Therefore, such an image is transmitted to the analysis center, and the analysis center associates the amount of oil in the transformer 10 with the information about the transformer 10, that is, the information obtained from the information code 100, and the transformer 10 analysis processing can be performed.

The present embodiment is not limited to the one embodiment described above, and various modifications and extensions can be made without departing from the scope of the present embodiment. For example, transformer 10 may be configured to include a plurality of information codes 100 . That is, the transformer 10 may have a configuration in which each of the plurality of inspection objects is provided with the information code 100 . Since the transformer 10 is provided with a plurality of information codes 100, the inspector can easily notice any one of the information codes 100 and obtain the transformer information on the transformer 10 more reliably.

Also, the color of the base portion of the information code 100, that is, the so-called ground color, should be different from the color of the object to be inspected. That is, for the oil level gauge 12 whose surface is black, the background color of the information code 100 should be a color that stands out against black, such as white, yellow, or orange. Thereby, the information code 100 attached to the oil level gauge 12 can be made more conspicuous. Therefore, it becomes easier for the maintenance operator who goes to the site where the transformer 10 is installed to notice the information code 100, and the reading of the information code 100 can be further promoted. The information code 100 may be provided in the vicinity of the object to be inspected in the main body 11 of the transformer 10. In this case, the background color of the information code 100 is different from the color of the main body 11 of the transformer 10. Color it.

Also, the information code 100 may be provided on an object to be inspected other than the oil level gauge 12, for example, the thermometer 13. FIG. The thermometer 13 is a component that cannot be measured when the power of the transformer 10 is turned off. However, even such an inspection object may be visually inspected by an inspection operator during inspection, so the information code 100 may be provided for such an inspection object.

In particular, as illustrated in FIG. 4 , the thermometer 13 may be provided at a position distant from the main body 11 of the transformer 10 . In such a case, since the thermometer 13 is provided with the information code 100, even if the inspection operator is at a position away from the main body 11 of the transformer 10, the inspection operator can 100 readings may be allowed.

In the transformer 10, the information code 100 may be attached to any object to be inspected. Also, the information code 100 attached to the surface of the inspection object may be covered with a transparent protective film.

Also, the information code 100 is not limited to a rectangular shape, and may be polygonal such as a triangle or a pentagon, or may be circular or elliptical. In addition, the information code 100 is not limited to the QR code (registered trademark), and may be in another code format such as a bar code.
