Description

Technical Field

[0001] This invention relates to leakage current sensing conduits and electric shock protection devices including the same, and more specifically, to leakage current sensing conduits and electric shock protection devices including the same, which prevent leakage current from flowing to the outside when electrical equipment or devices, including ground electrical facilities such as streetlights, motors, transformers, and traffic lights, experience leakage current due to immersion in water or other reasons, thereby preventing electric shock accidents caused by leakage current. Furthermore, when leakage current occurs, it can be automatically recycled to the power supply side, thereby effectively preventing electric shock accidents. Moreover, it can improve management efficiency. Background Technology

[0002] Electric shock refers to the phenomenon caused when the leakage current generated in the human body exceeds a specified value when the current from the power source flows through the human body to the ground, which serves as the ground contact point.

[0003] Typically, a leakage current of 15mA or more will cause convulsions, while a leakage current of 50mA or more will lead to death. The main cause of death is cardiac arrest, where the current flowing through the heart damages nerves, causing the heart to stop beating.

[0004] The danger of electric shock is related to the resistance of the human body when an electric current is applied, which largely depends on the condition of the skin.

[0005] When electrical equipment, such as sockets, heaters, or lights, is submerged in water, if a person comes into contact with the water or the metal casing becomes electrified through the water, current will flow from the exposed conductors of the electrical equipment through the water and the person to the ground, which serves as the grounding point.

[0006] At this time, human skin is easily soaked with water, and under these circumstances, the contact resistance is extremely low, thus putting the body in a very dangerous state.

[0007] A short circuit between power lines occurs when the insulation between two lines decreases while their conductivity increases, causing a rapid flow of current that can lead to fires or other damage to electrical equipment.

[0008] Air is typically a highly insulating material, thus maintaining electrical insulation between two wires using air as the medium.

[0009] However, when a highly conductive fluid is filled between the two wires due to reasons such as immersion in water, the current between the phases will increase sharply, resulting in a short circuit.

[0010] Korean Patent Publication No. 2005-0037986 discloses a water-resistant electric shock device in which a metal plate or mesh is attached to the exposed charging part. When the device is immersed in water, the current leaking from the exposed charging part will be directed to the conductive metal plate or mesh, thereby preventing electric shock accidents.

[0011] The metal plate or metal mesh is connected to the neutral and ground terminals in the terminal block via wires. The metal plate is approximately 50cm x 30cm in size.

[0012] The prior art does not provide a detailed explanation of its principle. When immersed in water, a metal plate with a resistance much lower than that of water and the human body is placed between the submerged conductors and connected in parallel with the human body, thereby limiting the current flowing to the human body.

[0013] However, such metal plates or meshes have the following problems: they cannot effectively prevent leakage current from occurring because they cannot shield the electric field that emanates radially from the exposed charging section, and their installation is also limited.

[0014] Taking a street light as an example, the street light has the following structure: a light pole support is mounted on the upper part of the ground via a flange formed at the lower end of the light pole support; the lower part of a light arm, whose width gradually narrows upwards, is connected to the upper end of the light pole support via a separate tapered connecting component. In this case, a luminaire arm is attached to the upper end of the light arm, and the luminaire arm is fitted with a luminaire.

[0015] These streetlights contain various electrical facilities, such as power lines and transformers, to power the lights.

[0016] However, this type of electrical equipment will leak current when submerged in water, and the current will flow down the streetlight with the rainwater. As a result, people who touch the streetlight or are near it will be electrocuted. Summary of the Invention

[0019] Furthermore, another objective of the present invention is to provide a leakage current sensing conduit and an electric shock protection device including the conduit, which can automatically perform leakage current detection and recovery, thereby effectively preventing electric shock accidents and improving management efficiency.

[0042] The additional objects, features and advantages of the present invention can be more precisely understood from the following detailed description and accompanying drawings.

[0043] Before describing the invention in detail, it is clear that the invention can be modified in various ways and can have various embodiments. The examples described below and shown in the figures are not intended to limit the invention to a specific form, but should be understood to include all modifications, equivalent technical solutions or alternative technical solutions included in the concept and technical scope of the invention.

[0044] Furthermore, in the description with reference to the accompanying drawings, the same structural elements are assigned the same reference numerals regardless of the drawing references, and repeated descriptions of them are omitted. In the description of the present invention, if the gist of the invention is unclear when it is determined to be a specific description of related prior art, detailed descriptions of those techniques will be omitted.

[0045] Hereinafter, with reference to the accompanying drawings, a preferred embodiment of the leakage current sensing conduit and an electric shock protection device including the conduit will be described in detail.

[0046] First, refer to Figures 1 to 3 The leakage current sensing wire of the present invention will be described in detail.

[0047] Figure 1 To illustrate the leakage current sensing wire of the present invention, Figure 2 A diagram showing the structural portion of the leakage current sensing wire of the present invention is provided. Figure 3 To illustrate the leakage current shielding tube portion included in the leakage current sensing conduit of the present invention, part (A) is a transverse sectional view and part (B) is a longitudinal sectional view.

[0048] The leakage current sensing conduit of the present invention is a conduit for guiding wires used to supply power to electrical equipment or electrical devices, such as... Figures 1 to 3 As shown, it generally includes a first leakage current sensing tube section 110, a first leakage current inductor section 120, a second leakage current sensing tube section 130, and a second leakage current inductor section 140. For example, when the electrical equipment is a street light, the wire used to supply power to the street light is connected by passing a leakage current sensing conduit underground.

[0049] Specifically, the leakage current sensing conduit of the present invention is a conduit for guiding wires used to supply power to electrical equipment or electrical devices, such as... Figures 1 to 3 As shown, it includes: a first leakage current sensing tube section 110, which guides wires internally and is made of an insulating material; a first leakage current inductor section 120, which is disposed inside the first leakage current sensing tube section 110 and transmits leakage current to a second leakage current inductor section 140 disposed on the second leakage current sensing tube section 130 below; a second leakage current sensing tube section 130, which is made of an insulating material and is disposed at one end of the first leakage current sensing tube section 110; and a second leakage current inductor section 140, which is disposed on the second leakage current sensing tube section 130 and is electrically connected to the first leakage current inductor section 120.

[0050] The first leakage current sensing tube 110 is a tubular structure made of insulating material and guided by an internal wire.

[0051] Specifically, the first leakage current sensing tube portion 110 is made of a resin material such as plastic, and the insulating material used to form it is not limited to this. Preferably, although it will be described below, considering that the first leakage current inductor portion 120 is provided in the first leakage current sensing tube portion 110, it should be formed of a resin material considering moldability and manufacturability (e.g., extrusion).

[0052] Furthermore, when the length of the first leakage current sensing tube section 110 is extended, two or more can be connected. In this case, the first leakage current inductor sections 120 formed between adjacent first leakage current sensing tube sections 110 can be connected by a connector that enables electrical connection.

[0053] Next, the first leakage current inductor section 120 is disposed inside the first leakage current sensing tube section 110, and transmits the leakage current to the second leakage current sensing tube section 130 when leakage current occurs.

[0054] Specifically, the first leakage current inductor section 120 is composed of a conductor formed on the inner wall (inner surface) of the first leakage current sensing tube section 110. Preferably, at least one conductor strip is formed into a spiral and disposed on the inner surface of the first leakage current sensing tube section 110.

[0055] Preferably, a spiral groove is formed on the inner surface of the first leakage current sensing tube portion 110, and the first leakage current inductor portion 120 is disposed in the spiral groove.

[0056] The first leakage current inductor section 120 may be formed by melting a conductive component capable of being combined with resin, such as graphene or graphite, in a spiral groove. Preferably, the conductivity of the first leakage current inductor section 120 is 200 ohms (Ω) or less.

[0057] Furthermore, the first leakage current inductor section 120 is disposed in the spiral groove of the first leakage current sensing tube section 110, such that the deviation D of the upper surface of the first leakage current inductor section 120 (or the height of the first leakage current inductor section 120) relative to the upper surface of the spiral groove is at least 1 mm. This tolerance is formed to prevent short circuits and withstand voltage when the wire sheath is damaged.

[0058] The figure shows four spiral grooves formed at 90° intervals in the first leakage current sensing tube section 110, so as to provide the first leakage current inductor section 120.

[0059] As described above, when two or more first leakage current inductor sections 120 are formed (four in the figure), even if a portion is damaged, the leakage current inductor section is always connected to the second leakage current inductor section 140 of the second leakage current sensing tube section 130. Therefore, even if the insulation of the wire is damaged at a location inside the first leakage current sensing tube section 110 and leakage current occurs, it can be shielded and transmitted to the neutral line (the leakage current transmission section of the second leakage current inductor section 140).

[0060] Furthermore, as shown in the figure, the spiral groove formed in the first leakage current sensing tube section 110 can be formed as a semicircle, but is not limited to this, and can also be formed in various shapes or forms.

[0061] Next, the second leakage current sensing tube 130 is made of an insulating material and is formed from a tubular body formed at one end of the first leakage current sensing tube 110.

[0062] The second leakage current sensing tube 130 is detachably connected to the first leakage current sensing tube 110. The connecting end of the second leakage current sensing tube 130 (connected to one side end of the first leakage current sensing tube 110) has a size and shape that can be combined with the inside of the first leakage current sensing tube 110.

[0063] Furthermore, an insulating rubber layer is formed on the inner surface of the second leakage current sensing tube section 130, thereby achieving internal insulation. Moreover, a hexagonal nut can be formed at the center of the outer surface of the second leakage current sensing tube section 130. This is to facilitate fixing or detaching the connected object when the upper sensing part 142 of the second leakage current inductor section 140, which will be described below, is formed in a threaded form.

[0064] Next, the second leakage current inductor section 140 is a structural section that is provided in the second leakage current sensing tube section 130 and electrically connected to the first leakage current inductor section 120.

[0065] Specifically, the second leakage current inductor section 140 includes: a lower inductor section 141, formed on the lower part of the outer surface of the second leakage current sensing tube section 130, and electrically connected to the first leakage current inductor section 120; and an upper inductor section 142, formed on the upper part of the outer surface of the second leakage current sensing tube section 130, and electrically connected to the lower inductor section 140.

[0066] The lower sensor section 141 is formed in a spiral shape that is identical to the spiral groove pattern formed on the inner wall (inner surface) of the first leakage current sensing tube section 110. When the second leakage current sensing tube section 130 is combined with the inner side of the first leakage current sensing tube section 110, the lower sensor section 141 of the second leakage current inductor section 140 can be in close contact with and electrically connected to the first leakage current inductor section 120.

[0067] The lower sensor section 141 can be formed in a threaded shape. In this case, by tapping the inner surface of the first leakage current sensing tube section 110 and threading it, an electrical connection can be achieved with the first leakage current inductor section 120.

[0068] The upper sensor section 142 can be formed in a threaded shape. As described above, this can be easily coupled to the mating object by a nut and transmit leakage current.

[0069] Furthermore, a hexagonal nut can be formed at the center of the outer surface of the second leakage current sensing tube portion 130. In this case, a through hole is provided near the proximal end portion of the hexagonal nut, that is, on the inner edge side of the hexagonal nut, and the lower sensor portion 141 and the upper sensor portion 142 are connected through the through hole.

[0070] In the second leakage current inductor section 140 as described above, when the first leakage current sensing tube section 110 and the second leakage current sensing tube section 130 are combined, the lower inductor 141 is in close contact with the first leakage current inductor section 130, and the leakage current generated from the first leakage current sensing tube section 110 is transmitted through the second leakage current sensing tube section 130 to the neutral line second leakage current inductor section 140.

[0071] On the other hand, the present invention includes a leakage current automatic recovery module 200 connected to the leakage current sensing conduit 100 of the present invention and causing the leakage current transmitted from the leakage current sensing conduit 100 to automatically flow to the neutral wire of the wire, such leakage current automatic recovery module 200 being included in the electric shock protection device of the present invention.

[0072] Reference Figure 4 and Figure 5 The automatic leakage current recovery module 200 will be described in detail below.

[0073] Figure 4 The diagram illustrates the structure of the leakage current sensing conduit and the automatic leakage current recovery module included in the electric shock protection device of the present invention. Figure 5 The figure illustrates an embodiment of the automatic leakage current recovery module included in the electric shock protection device of the present invention.

[0074] like Figure 4 and Figure 5 As shown, the automatic leakage current recovery module 200 is a structural part that allows the leakage current transmitted from the leakage current sensing conduit 100 to automatically flow to the neutral wire of the wire.

[0075] In other words, the automatic leakage current recovery module 200 is a structural part that can automatically recover leakage current. Regardless of the direction in which the live wire L and the neutral wire N are connected at the inlet, it automatically switches to connect the neutral wire N to the leakage current shielding device.

[0076] like Figure 5 As shown, the automatic leakage current recovery module 200 generally includes an input section 210, a constant voltage section 220, a NAND gate section 230, an AND gate section 240, an electromagnetic switch section 250, and a display section 260.

[0077] The inlet section 210 is a structural part that connects to the live wire L and the neutral wire N that enter from the outside.

[0078] In the constant voltage section 220, the live wire L and the neutral wire N are connected to the grounding side G and the Zener diode ZD respectively and output a specified voltage. The capacitor C serves to maintain the specified voltage.

[0079] If both the first input 1 and the second input 2 from the live wire L are “H (High)”, then the NAND gate 230 outputs the logic value “L (Low)” at output 4. If both the first input 1 and the second input 2 from the live wire L are “L”, then the logic value “H” is output at output 4.

[0080] If both the first input 1 and the second input 2 from the live wire L are “H”, then the AND gate 240 outputs the logic value “H” at output 4. If both the first input 1 and the second input 2 from the live wire L are “L”, then the logic value “L” is output at output 4.

[0081] If the output of NAND gate 230 is “L” and the output of AND gate 240 is “H”, then electromagnetic switch 250 connects output 6 to terminal 5. If the output of NAND gate 230 is “H” and the output of AND gate 240 is “L”, then output 6 connects to terminal 8.

[0082] The automatic leakage current recovery module 200 may also include a display unit 260. If the upper side of the display unit 260 is connected to the live wire L, the upper light-emitting diode 261 can emit light. If the lower side is connected to the live wire L, the lower light-emitting diode 262 can emit light.

[0083] The following explanation will be based on the example of the first terminal TH21 of the inlet unit 210 being connected to the live wire L and the second terminal TH22 being connected to the neutral wire N.

[0084] Since the first terminal TH21 of the input section 210 is connected to the live wire L, when “H” is input to the first input 1 and the second input 2 of the NAND gate section 230, the NAND gate section 230 will output “L”. Similarly, when “H” is input to the first input 1 and the second input 2 of the AND gate section 240, the AND gate section 240 will output “H”. In this case, since the output of the NAND gate section 230 is “L” and the output of the AND gate section 240 is “H”, the electromagnetic switch section 250 will connect output 6 to terminal 5.

[0085] Therefore, the neutral line N of the second terminal TH22 connected to the inlet section 210 is connected to the leakage current sensing wire 100. That is, the leakage current generated from the leakage current sensing wire 100 will flow to the neutral line N side of the power supply side.

[0086] Among them, the FG terminal in the leakage current sensing conduit 100 is the grounding terminal, and the FC terminal is, for example, the terminal connected to the housing of the electrical device (lamp pole). Because of the presence of the FC terminal, when the lamp pole is immersed in water, even if a pedestrian touches the lamp pole, the leakage current will not flow in the pedestrian's body.

[0087] On the other hand, the present invention includes the leakage current sensing conduit 100 and the leakage current automatic recovery module 200, as described above. Figures 6 to 11 The present invention will be described in detail with respect to the anti-electric shock device including the leakage protection unit 300.

[0088] Figure 6 The diagram shows a partial structural component constituting the electric shock protection device of the present invention. Figure 7 The diagram shows the leakage protection unit of the present invention in an exploded view. Figure 8 A diagram illustrating the application portion included in the leakage protection unit of the electric shock protection device of the present invention is provided. Figure 9 The diagram illustrates the application connection portion included in the leakage protection unit of the electric shock protection device of the present invention. Figure 10 The figure illustrates the application reminder unit included in the leakage protection unit of the electric shock prevention device of the present invention. Figure 11 The diagram illustrates the anti-electric shock portion included in the leakage protection unit of the anti-electric shock device of the present invention.

[0089] The electric shock protection device of the present invention includes: a leakage current sensing conduit 100; an automatic leakage current recovery module 200, which causes the leakage current transmitted from the leakage current sensing conduit 100 to automatically flow to the neutral wire of the wire (power supply line); and a leakage current protection unit 300, which connects the neutral wire of the wire to the power supply object and prevents leakage current when immersed in water.

[0090] The leakage current sensing conduit 100 and the leakage current automatic recovery module 200 have been described above. Therefore, detailed descriptions of them will be omitted, and the leakage protection unit 300 will be described instead.

[0091] The leakage current protection unit 300 includes: a housing portion 310; an application portion 320, built into the housing portion 310, for electrically connecting the wire to the power supply object (in the case of a street light); a recovery portion 330, installed in the application portion 320, connected to the neutral wire of the wire through the application portion 320 for recovering leakage current; and an anti-electric shock portion 340, built into the housing portion 310, configured to surround the application portion 320 and connected to the recovery portion 330, to prevent current from flowing from the application portion 320 to the recovery portion 330 and causing electric shock when immersed in water.

[0092] As an example, the housing portion 310 includes a lower housing portion 311 and an upper housing portion 312, wherein the upper housing portion 312 covers the upper opening area of ​​the lower housing portion 311. The lower housing portion 311 can be fixedly mounted on the inner wall of the power supply object.

[0093] An application part 320 is installed in the housing part 310. Using the application part 320 as a medium, an electric wire is connected to the power supply object, thereby enabling the power supply object to work (in the case of a street lamp, turning on the light).

[0094] As an example, the application unit 320 may include an application connection unit 321 and an application reminder unit 322.

[0095] The connection part 321 can be connected to a wire to receive power, and can also exclusively supply power to other power sources.

[0096] The connection part 321 may include a connection input part 351, a connection connection part 352, and a connection output part 353.

[0097] A pair of connection input sections 351 are arranged on the left and right sides, and each can be connected to the live wire and the neutral wire of the power line.

[0098] One end of the connection portion 352 is connected to the connection input portion 351 and can be electrically connected to at least one of the application reminder portion 322 and the power supply object. As an example, the connection portion 352 may include: a first connection portion 361, which extends laterally from the connection input portion 351 and is connected to the application reminder portion 322; and a second connection portion 362, which extends from the first connection portion 361 and is connected to the upper sensor 142 of the leakage current sensing conduit 100 through the application reminder portion 322.

[0099] A pair of connection outputs 353 can be connected to at least one of the connection inputs 351 and the connection connectors 352. As an example, the connection outputs 353 are connected to each connection input 351 and are disposed below the connection inputs 351. The connection outputs 353 can be connected to the output of a wire.

[0100] On the other hand, connection cover portions 354 may be respectively covered on connection input portion 351 and connection output portion 353. Connection cover portions 354 include insulating material to protect the wires exposed for connection at connection input portion 351 and connection output portion 353, and to direct leakage current toward the anti-electric shock portion 340.

[0101] Next, the reminder unit 322 can inform the recycling unit 330 and the power cord whether they are properly installed. For example, when the worker properly connects the recycling unit 330 to the reminder unit 322 and properly connects the power cord to the reminder unit 322, the reminder unit 322 can indicate that it is in a normal installation state through sound or light.

[0102] The reminder unit 322 may include a housing unit 371, a reminder board unit 372, and a reminder light unit 373.

[0103] The housing portion 371 may be mounted on the housing portion 310. The housing portion 371 may include an upper housing and an upper housing covering the upper opening area of ​​the lower housing.

[0104] The reminder board portion 372 can be attached to the housing portion 371 and connected to the application connection portion 321. As an example, the reminder board portion 372 includes circuitry for lighting the lamp during normal operation and can be connected to the second connection portion 362. This reminder board portion 372 can be electrically connected to the recycling portion 330. The reminder board portion 372 can connect the recycling portion 330 to the neutral wire of the electrical wire.

[0105] The reminder light unit 373 illuminates when the connection between the recycle unit 330 and the wire is normal. For example, the reminder light unit 373 can be mounted on the reminder board unit 372, and a reminder switch unit 372a can be added. Therefore, if the recycle unit 330 and the wire are electrically connected to the reminder board unit 372, even if the position of the live wire and neutral wire connection at the connection input unit 351 changes, the reminder light unit 373 can illuminate while the recycle unit 330 and the neutral wire remain connected.

[0106] The reminder application part 322 may also include a reminder grounding part 374. The reminder grounding part 374 can connect the reminder substrate part 372 and the grounding wire part g. As an example, the reminder grounding part 374 may include: a first grounding plate part 375, which is coupled to the reminder substrate part 372; a second grounding plate part 376, which extends upward from the first grounding plate part 375 and passes through the housing part 371; a third grounding plate part 577, which bends downward from the second grounding plate part 376 and is close to the outside of the housing part 371; and a fourth grounding plate part 378, which extends laterally from the third grounding plate part 377 and is connected to the grounding wire part g. The fourth grounding plate part 378 is supported by a support protrusion projecting outward from the housing part 371. This reminder grounding part 374 can ground the system when leakage current cannot be recovered through the neutral wire.

[0107] Next, the recovery unit 330 can be installed in the application unit 320, connected to the neutral wire of the wire, and recover the leakage current.

[0108] The recycling section 330 can be formed of a conductor and can be connected to the neutral wire of the wire via the substrate circuit of the application section 320.

[0109] Four recycling sections 330 are embedded in the outer casing 371 and pass through it vertically to be electrically connected to the reminder substrate 372. The upper and lower ends of the recycling sections 330 can be electrically connected to the anti-electric shock section 340.

[0110] The anti-electric shock part 340 can be built into the housing part 310, configured to surround the application part 320, and formed of a conductor and connected to the recovery part 330 to prevent current from flowing from the application part 320 to the recovery part 330 and causing electric shock when immersed in water. As an example, the housing part 310 can be made of insulating material, and the anti-electric shock part 340 can recover leakage current that moves to drain through the gaps in the housing part 310.

[0111] The electric shock protection part 340 may include a side protection part 341 and an upper protection part 342.

[0112] The side protection part 341 can be configured to surround the side of the application part 320. As an example, the side protection part 341 can surround the side of the application connection part 321, the application reminder part 322, and the leakage current automatic recovery module 200.

[0113] A pair of side-blocking portions 341 can be separated, or one can form a closed curve. The side-blocking portion 341 can be supported by the inner wall of the housing portion 310, and the position of the side-blocking portion 341 can be adjusted as needed to change the interval between the side-blocking portion 341 and the application portion 320.

[0114] The upper prevention part 342 can be connected to the side prevention part 341 and can be configured to surround the upper surface of the application part 320. As an example, the upper prevention part 342 can be disposed above the application connection part 321, the application reminder part 322, and the leakage current automatic recovery module 200. The upper prevention part 342 can be supported by the side prevention part 341 or by the housing part 310, and the position of the upper prevention part 342 can be adjusted as needed to change the interval between the upper prevention part 342 and the application part 42.

[0115] More specifically, the side protection part 341 may include a side body part 391, a side connecting part 392, a side cover part 393, a side protrusion part 394, and a side support part 395.

[0116] The side body portion 391 may cover the side of the application portion 320. As an example, the side body portion 391 may include: a first side body portion 391-1, covering the side of the wire and the application connection portion 321; and a second side body portion 391-2, extending from the first side body portion 391-1, covering the side of the leakage current automatic recovery module 200 of the application reminder portion 322.

[0117] The side connecting portion 392 can be bent from the front end of the side body portion 391 and connected to the wire. As an example, the side connecting portion 392 can be close to the wire and disposed between the housing portion 310 and the wire. The side connecting portion 392 can cover the front of the application portion 320.

[0118] The side cover portion 393 can be bent from the rear end of the side body portion 391 and surround the application portion 320. As an example, the side cover portion 393 can cover the rear of the application portion 320. A hole for passing a wire can be formed in the side cover portion 393.

[0119] The side protrusion 394 can extend laterally from the side body portion 391 and connect to the application portion 320. As an example, the side protrusion 394 formed at the lower end of the first side body portion 391-2 can be provided below the application reminder portion 322. The side protrusion 394 and the application reminder portion 322 can be combined in the housing portion 310 and can be connected to the side protrusion 394 of the retraction portion 43 provided in the application reminder portion 322.

[0120] The side support portion 395 can protrude upward from the side body portion 391 and support the upper prevention portion 342. As an example, the side support portion 395 can protrude from the upper ends of the first side body portion 391-1 and the second side body portion 391-2 respectively and be combined with the upper prevention portion 342.

[0121] According to the present invention, leakage current sensing conduit and electric shock protection device including the conduit reliably prevent leakage current from flowing to the outside due to immersion in water or other reasons, thereby preventing electric shock accidents caused by leakage current and preventing personal injury. Even if leakage current occurs due to damage to the insulation of the wire protection and the use wire, the leakage current is prevented from being released to the outside by shielding the leakage current.

[0122] Furthermore, the present invention has the following advantages: when leakage current occurs, it can be automatically recovered, thereby improving management efficiency; and it is applicable to a variety of electrical equipment or devices such as streetlights, motors, transformers, and traffic lights, thus having universality.
