Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of surge arrester components, and in particular to a visual surge arrester indicating device. Background Technology
[0002] A surge arrester is an electrical component that protects electrical equipment. It typically consists of a zinc oxide element and a metal casing. When struck by lightning, the surge arrester quickly generates a high-voltage signal, diverting the current to the ground and protecting the electrical equipment from damage. However, if the received lightning current exceeds its withstand limit, the surge arrester's components will burn out due to the high temperature.
[0003] As can be seen from the principle, when a surge arrester is struck by lightning, only the internal current changes. Unless one witnesses the lightning strike or directly observes the surge arrester burning out, it is difficult to determine whether the surge arrester has been struck by lightning or whether the internal components have been damaged. Therefore, a device is needed to visually demonstrate whether a surge arrester has been struck by lightning by showing changes in current, so that maintenance personnel can conduct regular inspections of the surge arrester. Utility Model Content
[0004] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.
[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a visual surge arrester indicator device. The indicator device is added to a conventional surge arrester, and the current is connected to the indicator device in series. When the surge arrester is struck by lightning, the current changes, and the rotating blades inside the indicator device rotate a certain angle accordingly. A shielding plate is provided on the detachable transparent top cover to partially block the rotating blades located below, leaving only one blade exposed. Each blade is set with a different color to indicate different working states of the surge arrester. Maintenance personnel on the ground or drones in the air can observe the exposed blades and determine the current status of the surge arrester based on the color, thus achieving visual observation.
[0006] This utility model provides a visual surge arrester indicator device, including a docking post with a conductive core inside, a housing disposed on the side of the docking post and having a receiving cavity inside, a rotating assembly disposed in the receiving cavity, and a transparent top cover fastened to the housing. A shielding plate is disposed on the transparent top cover. The rotating assembly includes a rotating motor and a rotating blade. One side of the rotating motor is connected to the receiving cavity, and the rotating blade is rotatably connected to the rotating shaft on the other side of the rotating motor. The shielding plate is located above the rotating assembly, and the bottom end of the shielding plate extends above the rotating blade and is higher than the axis of the rotating blade.
[0007] The docking post with a conductive core is used to connect with the surge arrester. The current signal is guided to the control component through series connection to detect current changes, thereby driving the rotating component to rotate accordingly. The specific structure of the docking post can be referred to in the existing technology, which will not be elaborated here. The outer shell with a receiving cavity is used to house the rotating component. After being combined with the transparent top cover, the maintenance personnel can directly observe the rotation of the rotating component from the outside. Under electric drive, the rotating motor drives the rotating blades to rotate. The shielding plate on the transparent top cover blocks several blades on the upper side during rotation, leaving only one blade on the lower side that can be observed from the outside, thereby realizing the indication function.
[0008] In some embodiments, the rotating blade includes at least three blades, each of which is decorated with a different color. The three blades are green, red, and yellow, with each color representing a different state of the surge arrester. Green indicates that the surge arrester is operating normally and has not been struck by lightning. If it has been struck by lightning, the red blade rotates downwards, indicating that the corresponding surge arrester was struck by lightning in the past but the internal components of the surge arrester were not damaged. If the internal components of the surge arrester were damaged by lightning, the yellow blade rotates downwards.
[0009] In some embodiments, each fan blade has an extension plate extending vertically from its end, the extension direction of which is parallel to the rotation axis of the rotary motor. Since the transparent top cover may reflect light during outdoor use due to sunlight or rain, an extension plate is provided extending vertically from the fan blade. This extension plate is also colored the same as the corresponding fan blade, thereby increasing the visible area, eliminating the effect of reflection, and facilitating observation by maintenance personnel on the ground or by drones in the air.
[0010] In some embodiments, a control component is further included, disposed within the receiving cavity. The control component includes a control chip and a battery, with the battery positioned between the rotating component and the docking post. The control chip is mounted on the battery. The control component receives current signals from the surge arrester and monitors the arrester's operating status through current changes. It should be understood that the technique of monitoring whether a surge arrester has been struck by lightning and whether its internal components have been damaged by current changes is well-known to those skilled in the art. Similarly, controlling the rotating blades to rotate at a fixed angle using the control chip, causing a specific blade to rotate downwards, is also a common technique. The involvement of software programs does not mean that this application is not within the scope of protection of this utility model. The battery powers the various components; specific details can be found in existing technology and will not be elaborated upon here.
[0011] In some embodiments, the shielding plate is a solar panel, which is electrically connected to the control chip and the rotating motor. Referring to existing solar panel structures, solar panels are typically black, which is beneficial for absorbing light and heat, thus shielding the rotating blades located below. The shielded portion of the rotating blades is not visible from the outside. Simultaneously, the solar panel can also power other components inside the indicating device, effectively utilizing the solar panel for two purposes.
[0012] In some embodiments, a photosensitive recognition component is further disposed within the receiving cavity, between the extension plate and the rotary motor, and electrically connected to the control chip. To ensure that the fan blades, each with a corresponding color, rotate to the lower, observable area, a photosensitive recognition component is disposed on the lower side of the receiving cavity, located between the extension plate and the rotary motor. When the fan blades are fully rotated to the lower position, the light is blocked, thereby generating a signal that is sent to the control chip, notifying the control chip that the fan blades are in position. It should be understood that the control program that uses photosensitive detection to determine whether an object is in position is a common technical solution in the prior art and is well known to those skilled in the art.
[0013] In some embodiments, the outer casing has several screw holes around its perimeter, and a fixing screw is correspondingly screwed onto the transparent top cover. The fixing screw secures the transparent top cover and the outer casing through the screw holes. By providing multiple screw holes and fixing screws, the transparent top cover can be removed, facilitating maintenance personnel to periodically inspect the indicating device or replace internal components.
[0014] In some embodiments, the transparent top cover is made of plastic or resin. Since the surge arrester needs to withstand lightning strikes, the indicating device installed on the surge arrester should also be made of insulating material; therefore, the transparent top cover is made of plastic or resin accordingly.
[0015] By adopting the above technical solution, the beneficial effects of this utility model are:
[0016] This invention adds an indicator device to a conventional surge arrester. Current is connected to the indicator device in series. When the surge arrester is struck by lightning, the current changes, and the rotating blades inside the indicator device rotate a certain angle accordingly. A shield is provided on the detachable transparent top cover to partially block the rotating blades located below, leaving only one blade exposed. Each blade is set with a different color to indicate different working states of the surge arrester. Maintenance personnel on the ground or drones in the air can observe the exposed blades and determine the current status of the surge arrester based on the color, thus achieving visual observation.

[0042] Reference Figure 1 , Figure 1 This is a schematic diagram of the overall structure of the surge arrester in some embodiments of this utility model.
[0043] According to some embodiments of the present invention, the present invention provides a visual lightning arrester indicator device, including a docking post 1 with a conductive core 2 inside, a housing 3 disposed on the side of the docking post 1 and having a receiving cavity 4 inside, a rotating assembly 5 disposed in the receiving cavity 4, and a transparent top cover 6 fastened to the housing 3, the transparent top cover 6 being provided with a shielding plate 7; the rotating assembly 5 includes a rotating motor 51 and a rotating blade 52, one side of the rotating motor 51 being connected to the receiving cavity 4, the rotating blade 52 being rotatably connected to the rotating shaft on the other side of the rotating motor 51, the shielding plate 7 being located above the rotating assembly 5, the bottom end of the shielding plate 7 extending above the rotating blade 52 and the bottom end of the shielding plate 7 being higher than the axis of the rotating blade 52.
[0044] The docking post 1, equipped with a conductive core 2, is used to connect with the surge arrester. The current signal is guided to the control component 8 through series connection to detect current changes, thereby driving the rotating component 5 to rotate accordingly. The specific structure of the docking post 1 can be referred to in the prior art, and will not be elaborated here. The outer shell 3, equipped with a receiving cavity 4, is used to house the rotating component 5. After being combined with the transparent top cover 6, maintenance personnel can directly observe the rotation of the rotating component 5 from the outside. Under electric drive, the rotating motor 51 drives the rotating blade 52 to rotate. The shielding plate 7 on the transparent top cover 6 blocks several blades on the upper side during rotation, leaving only one blade on the lower side that can be observed from the outside, thereby realizing the indication function.
[0045] Reference Figure 2 , Figure 2 This is a schematic diagram showing the positional relationship between the baffle plate and the rotating component in some embodiments of this utility model.
[0046] According to some embodiments of this utility model, optionally, the rotating blade 52 includes at least three blades, each of which is decorated with a different color. The three blades are green, red, and yellow, each color representing a different state of the surge arrester. Green indicates that the surge arrester is operating normally and has not been struck by lightning. If it has been struck by lightning, the red blade rotates downwards, indicating that the corresponding surge arrester was struck by lightning in the past but the internal components of the surge arrester were not damaged. If the internal components of the surge arrester were damaged by lightning, the yellow blade rotates downwards.
[0047] Each fan blade has a vertically extending extension plate 53 at its end, and the extension direction of the extension plate 53 is parallel to the rotation axis of the rotary motor 51. Since the transparent top cover 6 may reflect light during outdoor use due to sunlight or rain, an extension plate 53 is provided vertically to the fan blade. The extension plate 53 is also colored the same as the corresponding fan blade, thereby increasing the visible area, eliminating the effect of reflection, and facilitating observation by maintenance personnel on the ground or by drones in the air.
[0048] The indicating device also includes a control component 8, which is disposed within the receiving cavity 4. The control component 8 includes a control chip 82 and a battery 81. The battery 81 is disposed between the rotating component 5 and the docking post 1, and the control chip 82 is mounted on the battery 81. The control component 8 is used to receive current signals from the surge arrester and monitor the operating status of the surge arrester by monitoring current changes. It should be understood that the technology of monitoring whether the surge arrester has been struck by lightning and whether its internal components have been damaged by current changes is well known to those skilled in the art. Correspondingly, the program of controlling the rotating blade 52 to rotate at a fixed angle by the control chip 82, so that a specific blade rotates downward, is also a common technology. The involvement of software programs does not mean that this application is not within the scope of protection of the utility model. The battery 81 is used to power the various components, and specific details can be found in the prior art, which will not be elaborated here.
[0049] The shielding plate 7 is a solar panel, which is electrically connected to the control chip 82 and the rotary motor 51. Referring to existing solar panel structures, solar panels are typically black, which is beneficial for absorbing light and heat, thus shielding the rotating blade 52 located below. The shielded portion of the rotating blade 52 is not visible from the outside. Simultaneously, the solar panel can also power other components inside the indicating device, effectively utilizing the solar panel for two purposes.

[0051] Optionally, according to some embodiments of this utility model, a light-sensing identification component 9 is further provided inside the receiving cavity 4. The light-sensing identification component 9 is disposed between the extension plate 53 and the rotary motor 51, and is electrically connected to the control chip 82. In order to make the fan blade with the corresponding color rotate to the lower observable area, the light-sensing identification component 9 is provided on the lower side of the receiving cavity 4, and is located between the extension plate 53 and the rotary motor 51. When the fan blade is fully rotated to the lower position, the light is blocked, thereby generating a signal sent to the control chip 82 to notify the control chip 82 that the fan blade has reached its position. It should be understood that the control program that detects whether the object is in position by light sensing is a common technical solution in the prior art and is well known to those skilled in the art.
[0052] The outer casing 3 has several screw holes around its perimeter, and corresponding fixing screws are screwed onto the transparent top cover 6. These fixing screws secure the transparent top cover 6 and the outer casing 3 through the screw holes. The multiple screw holes and the fixing screws allow the transparent top cover 6 to be removed, facilitating maintenance personnel to periodically inspect the indicating device or replace internal components.
[0053] The transparent top cover 6 is made of plastic or resin. Since the surge arrester needs to withstand lightning strikes, the indicator device installed on the surge arrester should also be made of insulating material. Therefore, the transparent top cover 6 is made of plastic or resin.
