  By the way, in the visual inspection of the high-pressure cutout as described above, if the damage of the container of the high-pressure cutout is large, the damage of the high-pressure cutout can be easily confirmed visually, but small cracks / cracks, etc. Then, it is difficult to confirm visually from the ground. Moreover, visual confirmation becomes more difficult at night and in bad weather. For this reason, the inspector has to go up to the utility pole and perform a visual inspection, which not only requires a great deal of labor and time, but also may take a long time to restore the distribution line accident.

  Then, this invention aims at providing the electric equipment provided with the container made from a porcelain which can confirm visually the presence or absence of damage easily.

  In order to solve the above-mentioned problem, the invention according to claim 1 is an electric device including a porcelain container in which an electric member is disposed in a porcelain container and a coating material is applied to a surface of the container. In addition, a discolored light emitting material that discolors or emits light when the coating material is damaged and touches outside air is provided between the container and the coating material.

  According to the present invention, when the coating material or the container is damaged due to lightning or external force, the discolored light emitting material changes color or emits light by touching the outside air.

  According to a second aspect of the present invention, in the electric device according to the first aspect, the discolored light emitting material is composed of an ultraviolet light emitting material that emits light when receiving ultraviolet light.

  According to the present invention, when ultraviolet light is applied to the damaged part of the electrical equipment / coating material with an ultraviolet light or the like, the ultraviolet light emitting material that is the color changing light emitting material emits light.

  According to a third aspect of the present invention, there is provided the electrical apparatus according to the first or second aspect, wherein the storage chamber is cylindrical and has one opening closed by the container and the other opening closed by the coating material. A plurality of containers are disposed between the container and the coating material, and the discolored light emitting material is stored in a storage chamber of the container.

  According to the first aspect of the present invention, when at least the coating material of the container is damaged, the discolored light emitting material is discolored or emits light, so that it is possible to easily confirm whether or not the electric device is damaged visually. In other words, it is possible to check whether or not the container is damaged without climbing up to the utility pole, etc., and as a result, the labor and time required for inspection are significantly reduced and the time required for recovery from the distribution line accident is shortened. It becomes possible.

  According to the second aspect of the present invention, it is possible to easily confirm visually whether or not the electric device is damaged by performing a patrol inspection while applying an ultraviolet light or the like to the electric device to be inspected. In addition, since the ultraviolet light emitting material emits light when the electrical device is damaged, the presence or absence of damage can be easily confirmed visually even at night or in bad weather.

  According to the third aspect of the present invention, since the discolored light emitting material is accommodated in the housing chamber of the container sandwiched between the container and the coating material, even if the discolored light emitting material is gaseous or liquid, a predetermined amount It can be held properly. For this reason, various color-change light emitting materials suitable for the use environment can be disposed between the container and the coating material. Moreover, when the coating material is damaged, the storage chamber of the container is opened, so that the sound when the electric device is struck changes. That is, since the sound when the electric device is struck differs depending on whether or not the coating material is damaged, it is possible to easily check whether or not the electric device is damaged by the sound.

It is a perspective view which shows the high voltage | pressure cutout which concerns on Embodiment 1 of this invention. It is the figure (a) which shows the normal cross-sectional state of the high voltage | pressure cutout of FIG. 1, and the figure (b) which shows the cross-sectional state at the time of damage. It is a figure which shows the cross-sectional state of the high voltage | pressure cutout which concerns on Embodiment 3 of this invention. It is a top view which shows the accommodating body of the high voltage | pressure cutout of FIG.

  The present invention will be described below based on the illustrated embodiments.

(Embodiment 1)
FIG. 1 is a perspective view showing a high-pressure cutout (electric device including a porcelain container) 1 according to this embodiment, and FIG. The high-voltage cutout 1 is an electrical device in which an electrical member (not shown) such as a fuse is disposed in a porcelain container 2 and a coating material 3 is applied to the surface of the container 2.

  The container 2 is composed of a feldspar-like porcelain similar to a general insulator, and can be opened and closed in a substantially cubic shape. Further, it can be attached to the armature 100 of the utility pole via the mounting bracket 21. As shown in FIG. 2, the entire surface of the container 2 is a glaze made of feldsparic glass and is covered with a transparent coating material 3.

  Further, a color change material (color change light emitting material) 4 is disposed between the container 2 and the coating material 3 so as to cover the entire surface of the container 2. The color changing material 4 is composed of a chemical (such as potassium iodide) that changes color when exposed to outside air or air (oxygen, nitrogen, etc.), and the coating material 3 is damaged and changes color when exposed to the outside air. . That is, in a state where the outside air is not touched, the first color is exhibited, and when the outside air is touched, the second color is exhibited.

  Such a container 2, the coating material 3, and the color change material 4 are formed as follows, for example. That is, after the container 2 is formed and molded into a predetermined shape and dried, the color changing material 4 is applied to the entire surface of the container 2. Further, the coating material 3 is applied so as to cover the entire surface of the color changing material 4, fired, and sintered. Here, the color changing material 4 is applied to the entire surface of the container 2, but the color changing material 4 may be applied only to a portion where the container 2 or the coating material 3 may be damaged.

  Next, the operation of the high-pressure cutout 1 having such a configuration will be described. Here, the high-pressure cutout 1 is damaged by a lightning strike or an external force. When the container 2 is damaged, the coating material 3 is always damaged, and even when the coating material 3 is damaged, the container 2 may not be damaged. That is, whether the high-pressure cutout 1 is damaged or not is determined depending on whether or not the coating material 3 is damaged.

  For example, even if a lightning strike occurs, when the high-pressure cutout 1 is not damaged, the color changing material 4 is covered with the coating material 3 as shown in FIG. Is not in contact with outside air or air. For this reason, the entire high-pressure cutout 1 exhibits the first color of the color changing material 4. On the other hand, when the high-pressure cutout 1 is damaged by lightning, and the crack C occurs in the container 2 or the coating material 3 as shown in FIG. The portion and its periphery change to the second color. Thereby, the crack C periphery of the high-pressure cutout 1 exhibits the second color.

  As described above, according to the high pressure cutout 1, when at least the coating material 3 is damaged, the color changing material 4 is discolored and the periphery of the damaged portion of the high pressure cutout 1 exhibits the second color. It is possible to easily confirm the presence or absence of 1 damage visually. In other words, in the patrol for visually checking whether or not a large number of high-pressure cutouts 1 are damaged, only whether the entire high-pressure cutout 1 exhibits the first color, or even a part of the second color, The presence or absence of breakage of the high-pressure cutout 1 can be confirmed. Therefore, it is possible to confirm the presence or absence of damage from the ground without climbing up to the utility pole, and even when a small crack or crack is generated, it can be visually confirmed from the ground. As a result, the labor and time required for the inspection are remarkably reduced, the safety is remarkably improved, and the time required for recovery from the distribution line accident can be shortened. That is, when an accidental power failure occurs, the damaged high-pressure cutout 1 that is the cause of the accident can be found at an early stage, and a quick recovery operation can be performed.

(Embodiment 2)
This embodiment is different from the first embodiment in that an ultraviolet light emitting material (discolored light emitting material) 5 is disposed between the container 2 and the coating material 3. Here, about the structure equivalent to Embodiment 1, the description is abbreviate | omitted by attaching | subjecting the same code | symbol. The same applies to the third embodiment to be described later.

  The ultraviolet light-emitting material 5 is a light-emitting material that emits light when it receives ultraviolet light. Specifically, the ultraviolet light-emitting material 5 includes a phosphorescent agent and a fluorescent agent. That is, in the case of a phosphorescent agent, it absorbs light energy (ultraviolet rays) such as sunlight and fluorescent lamps and emits light, and then continues to emit light for a predetermined time. In the case of a fluorescent agent, it absorbs ultraviolet rays and absorbs electromagnetic waves. It is used properly depending on the installation environment of the high-pressure cutout 1 and the inspection method. The coating material 3 has a function / performance (UV cut) for blocking ultraviolet rays.

  As in the first embodiment, when the high-pressure cutout 1 is not damaged, the ultraviolet light emitting material 5 is covered with the coating material 3 as shown in FIG. Even if the cutout 1 is irradiated with ultraviolet rays, the ultraviolet light emitting material 5 does not emit light. On the other hand, when the high-pressure cutout 1 is damaged by a lightning strike or the like and a crack C occurs in the container 2 or the coating material 3 as shown in FIG. 2B, the ultraviolet light emitting material 5 is exposed to the outside air. . For this reason, when an ultraviolet ray is applied to the crack C of the high-pressure cutout 1, the ultraviolet light emitting material 5 emits light.

  As described above, according to this embodiment, it is possible to easily confirm visually whether or not the high pressure cutout 1 is damaged by performing a patrol inspection while applying an ultraviolet light or the like to the high pressure cutout 1 to be inspected. It becomes possible. Moreover, since the ultraviolet light emitting material 5 emits light when the high-pressure cutout 1 is damaged, the presence or absence of damage can be easily confirmed visually even at night or in bad weather.

(Embodiment 3)
In this embodiment, as shown in FIGS. 3 and 4, a container 6 is disposed between the container 2 and the coating material 3, and the color changing material 4 is stored in each storage chamber 61 of the container 6. However, the configuration is different from that of the first embodiment.

  That is, the container 6 is a honeycomb-shaped sheet material and includes a plurality of regular hexagonal cylindrical storage chambers 61. Such a container 6 is disposed so as to cover the entire surface of the container 2, and the color changing material 4 is stored in each storage chamber 61. Further, a film 7 is disposed so as to cover the upper surface of the container 6, and the coating material 3 is applied thereon. Thereby, one (lower side in FIG. 3) opening of each storage chamber 61 of the container 6 is closed by the container 2, and the other (upper side in FIG. 3) opening is coated with the coating material 7 via the film 7. 3 is closed.

  As in the first and second embodiments, when the high-pressure cutout 1 is not damaged, the discoloring material 4 is covered with the coating material 3, so that the discoloring material 4 does not touch the outside air or air. The entire high-pressure cutout 1 exhibits the first color of the color changing material 4. In addition, such a sound high-pressure cutout 1 has a relatively heavy and low sound when struck with a small hammer or the like because each housing chamber 61 is sealed and the color changing material 4 is housed.

  On the other hand, when the high pressure cutout 1 is damaged by a lightning strike or the like, the discoloring material 4 touches the outside air and changes to the second color, and the periphery of the crack C of the high pressure cutout 1 exhibits the second color. In addition, since the damaged high-pressure cutout 1 is not sealed in some of the storage chambers 61, a relatively light and high sound is emitted when it is struck with a small hammer or the like. In other words, the sound produced is different between the sound high-pressure cutout 1 and the damaged high-pressure cutout 1.

  Thus, according to this embodiment, since the color changing material 4 is accommodated in the storage chamber 61 of the container 6 sandwiched between the container 2 and the coating material 3, the color changing material 4 such as gaseous or liquid is used. Even in such a case, the predetermined amount of the color changing material 4 can be properly and reliably held. For this reason, various color-changing materials 4 suitable for the usage environment can be disposed between the container 2 and the coating material 3. In addition, it is possible to easily confirm whether or not the high-pressure cutout 1 is damaged by a sound generated when the high-pressure cutout 1 is struck. That is, it is possible to confirm the presence or absence of damage by patrol while hitting the high-pressure cutout 1 from the ground.

  Although the embodiment of the present invention has been described above, the specific configuration is not limited to the above embodiment, and even if there is a design change or the like without departing from the gist of the present invention, Included in the invention. For example, in Embodiment 3, the planar shape of the storage chamber 61 is a regular hexagon in order to ensure high strength. However, other shapes may be used. In addition, a film 7 is disposed below the container 6 (on the container 2 side), and the container 6 and the color changing material 4 held and sandwiched by the film 7 are arranged between the container 2 and the coating material 3. You may set up. Thereby, handling and arrangement | positioning of the discoloration material 4 become easier. Furthermore, in the above embodiment, the case of the substantially cubic high-pressure cutout 1 has been described, but it can also be applied to a cylindrical high-pressure cutout, and can also be applied to electrical equipment other than the high-pressure cutout, Of course.
