Description

Technical Field

[0001] This invention relates to a temperature measuring mechanism, and more specifically, to a temperature measuring mechanism with a structure that allows for easy attachment and detachment of an optical cable for measuring the temperature of an electric power line and enables accurate measurement of the temperature of the electric power line. Background Technology

[0002] A transformer is a device that receives a specified voltage and converts it into a different voltage for output. Transformers are widely used to minimize power loss during the transmission of electricity from the point of production to the point of consumption.

[0003] The transformer is connected to power lines that receive electricity and transmit the regulated electricity to the outside. These power lines connect the transformer to the point of consumption or production in a way that allows for energization.

[0004] Transformers and power lines are also types of equipment, and therefore, there are potential risks of damage during their operation. Typically, high-voltage current flows through transformers and power lines; therefore, temperature measurement can be used to detect potential damage in advance and to take swift action when abnormalities are detected.

[0005] When a transformer or power line is operating normally, a temperature within a preset range is detected, which indicates normal operation. If the detected temperature exceeds this range, the transformer or power line is considered to be operating abnormally, and appropriate measures can be taken.

[0006] In particular, optical fibers are widely used to detect heat generated in power lines. Light traveling along an optical fiber is sensitive to temperature changes, and its waveform changes accordingly. These waveform changes are transmitted to control centers, allowing administrators to identify anomalies in the power lines. For this purpose, optical fibers are wound into the power lines.

[0007] As mentioned above, high-voltage current is applied to power lines. Therefore, the work of winding optical fibers into power lines must be performed by skilled personnel. This may increase the cost of performing operations to measure the temperature of the power lines.

[0008] Additionally, preferably, the length of the optical fiber wound around the power line is more than a predetermined length to accurately measure the temperature of the power line. As the length of the wound optical fiber increases, additional components may be needed to secure it to the power line.

[0009] Korean Patent No. 10-0879035 discloses a multi-cable structure and its housing that includes an optical fiber for measuring temperature. Specifically, it discloses a multi-cable structure and its housing that includes an optical fiber for measuring temperature and a plurality of cables surrounding the optical fiber in a radial direction, enabling the detection of temperature changes in any one or more of the plurality of cables.

[0010] However, this type of multi-cable structure and its multi-cable housing require fiber optic cables from the manufacturing stage. That is, the multi-cable structures proposed in the existing literature are difficult to apply to power lines that are already in use or have been installed.

[0011] Korean Utility Model Approval No. 20-0429325 discloses a portable integrated clamp temperature measuring device for power cables. Specifically, it discloses a portable integrated clamp temperature measuring device for power cables that includes a clamp capable of engaging with a power cable and having a built-in temperature sensor for detecting the cable's temperature, as well as a main body for receiving the detected information.

[0012] However, this type of power cable temperature measuring device is primarily intended for one-time measurements. That is, the power cable temperature measuring devices described in the existing literature are difficult to configure for continuous measurement of the temperature at a specific location on the power line. Therefore, these power cable temperature measuring devices rely on manual measurement of the power line temperature by operators.

[0044] Invention Effects

[0045] As described above, the following effects can be achieved according to embodiments of the present invention.

[0046] First, the temperature measuring mechanism includes a plurality of housings that are joined together in a manner that allows them to be separated from each other. The first housing or the second housing is joined in a manner that allows it to rotate around each other, and can be joined by rotating toward each other, or can be separated by rotating in the opposite direction to each other.

[0047] When the temperature measuring mechanism is combined with the electric field lines, the first or second housing rotates in opposite directions to each other, exposing its internal space to the outside. After the electric field lines, etc., are housed in the space and pass through the housing, the first or second housing rotates towards each other and is then combined.

[0048] At this time, an optical cable for measuring the temperature of power lines, etc., is housed in the temperature measuring mechanism. When the first housing or the second housing rotates toward each other and engages with the power lines, etc., the optical cable is arranged to surround the outer periphery of the power lines, etc.

[0049] Therefore, the temperature measuring mechanism can be easily attached to or detached from power lines, etc., simply by attaching and disassembling the housing, making installation and separation easy. As a result, the time required for installing and disassembling the temperature measuring mechanism can be reduced, and the operation can be easily performed even by operators with low skill levels.

[0050] Furthermore, the housing, which comes into direct contact with the operator, is made of insulating material. As described above, the housing is composed of a plurality of partially separable components. After the operator operates the first or second housing to insert the power line into an open space, they can operate the first or second housing to attach the temperature measuring mechanism to the power line.

[0051] In other words, the installation of the temperature measuring device minimizes contact between workers and power lines. Therefore, when integrating the temperature measuring device into or separating it from power lines, safety accidents can be prevented.

[0052] In addition, a housing fastening part is provided in the temperature measuring mechanism. The housing fastening part is respectively provided in the first housing and the second housing, stably maintaining the joint state of the first housing and the second housing. Unless an external force of more than a specified magnitude is applied, the first housing and the second housing can remain in the joint state.

[0053] Therefore, the connection between the temperature measuring mechanism and the power line can be maintained stably. Furthermore, the power line housed in the temperature measuring mechanism and the optical cable used to measure the temperature of the power line are not affected by the external environment, thereby improving the reliability of temperature measurement.

[0054] In another embodiment, a cable winding section is provided in the temperature measuring mechanism. The cable winding section includes a columnar member that is coupled to and extends from the housing and a support member that supports the power lines. The support member is located at one end of the columnar member and has a larger cross-sectional area than the columnar member.

[0055] The optical cable is wound around the columnar member without swaying and is not loosened into the interior space of the housing by the supporting members. The supporting members are formed with a cross-sectional area having the same shape as the outer periphery of the power line, thereby supporting the outer periphery of the power line.

[0056] Furthermore, in another embodiment, a cable pad is provided in the temperature measuring mechanism. The cable pad includes a cable pad formed of a flexible material and through which an optical cable passes, and a pad support portion supporting the cable pad.

[0057] The optical cable is integrated with the cable pad, preventing it from shifting or detaching. The power lines housed within the casing are supported by the pad support, with the cable pad positioned between them. The cable pad is pressed and deformed against the pad support, allowing it to be stably positioned within it.

[0058] Therefore, the optical cable integrated with the temperature measuring mechanism can be stably kept in a wound state or in a state integrated with the cable pad. Similarly, the outer periphery of the power line is stably supported by the cable winding or cable pad, thus stably maintaining the connection between the temperature measuring mechanism and the optical cable or power line.

[0059] In addition, the temperature measuring mechanism includes a sliding prevention part. The sliding prevention part is configured to maintain the relative position of the electric field line and the temperature measuring mechanism. That is, the temperature measuring mechanism coupled to the electric field line will not move or shake arbitrarily.

[0060] Therefore, the temperature measuring mechanism can be accurately positioned within the extended power line to measure the temperature of the object. This allows the temperature measuring mechanism to obtain accurate temperature information at the precise location where the temperature to be measured is needed.

[0061] Furthermore, in various embodiments, the integration and support structure of the temperature measuring mechanism with the power line can be formed in various ways. The temperature measuring mechanism can be formed in the shape of a shell, with its internal space accommodating the power line. In another embodiment, the temperature measuring mechanism can be formed in the shape of an insulating cup to cover the insulator provided on the transformer and integrate with the power line.

[0062] Therefore, the design freedom of temperature measuring mechanisms can be increased. Furthermore, the installation location and components of temperature measuring mechanisms can be configured in a variety of ways. Attached Figure Description

[0078] Hereinafter, the temperature measuring mechanisms 10, 20, and 30 of the present invention will be described in detail with reference to the accompanying drawings.

[0079] In the following description, some structural elements may be omitted in order to make the features of the invention clearer.

[0080] 1. Definition of terms

[0081] As used in the following description, the term "connection" means that one or more components are connected in a manner that allows fluid to pass between them. In one embodiment, a connection can be formed by components such as pipes, tubes, and piping.

[0082] As used in the following description, the term "energized" means that one or more components are connected in a manner that enables them to transmit current or electrical signals to each other. In one embodiment, energization can be achieved through wired means based on conductors or the like, or wireless means such as Bluetooth, Wi-Fi, or RFID.

[0083] The terms “upper side,” “lower side,” “left side,” “right side,” “front side,” and “rear side” used in the following description can be found in [reference needed]. Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 9 as well as Figure 11We can understand this using the coordinate system shown in the diagram.

[0084] The following description assumes that the temperature measuring mechanisms 10, 20, and 30 of the present invention are used in conjunction with the power line W. However, it is understood that the temperature measuring mechanisms 10, 20, and 30 of each embodiment can be applied not only to the power line W, but also to any component that can be attached around the outer periphery.

[0085] 2. Description of temperature measuring mechanisms 10, 20, and 30 in embodiments of the present invention

[0086] The temperature measuring mechanisms 10, 20, and 30 of this embodiment of the invention can be detachably connected to the power line W. When the temperature measuring mechanisms 10, 20, and 30 are connected to the power line W, the optical cable C wound around the temperature measuring mechanisms 10, 20, and 30 can be configured to surround the power line W.

[0087] Therefore, the temperature change of the power line W can be detected by the change in the wavelength of the light traveling in the optical cable C.

[0088] Multiple temperature measuring mechanisms 10, 20, and 30 can be provided. These multiple temperature measuring mechanisms 10, 20, and 30 can be respectively installed at different positions on the extended power line W and detect the temperature of the power line W. The installed temperature measuring mechanisms 10, 20, and 30 can be held in a predetermined position by a sliding anti-slip part 40.

[0089] Therefore, the temperature measuring mechanisms 10, 20, and 30 can be held at the position of the object to be measured, thereby enabling accurate measurement of the temperature at a predetermined position.

[0090] The following is for reference Figures 1 to 8 The composition of temperature measuring mechanisms 10, 20, and 30 in embodiments of the present invention will be described in detail.

[0091] (1) Description of the temperature measuring mechanism 10 according to an embodiment of the present invention

[0092] Reference Figures 1 to 4 The diagram illustrates a temperature measuring mechanism 10 according to an embodiment of the present invention. The temperature measuring mechanism 10 of this embodiment includes a member that supports the power line W and stably positions the optical cable C on the outside of the supported power line W.

[0093] Therefore, the temperature measuring mechanism 10 of this embodiment can accurately detect the temperature change of the power line W while stably supporting it.

[0094] An optical cable C is wound inside the temperature measuring mechanism 10. The wound optical cable C is arranged adjacent to the power line W. The pattern of light traveling along the optical cable C changes according to the temperature change of the power line W, thereby enabling the detection of whether the power line W is abnormal.

[0095] The temperature measuring mechanism 10 can be detachably connected to the power line W. As described later, the interior of the temperature measuring mechanism 10 can be opened through the housing connection 150. Furthermore, after the power line W is inserted into the temperature measuring mechanism 10, the connection can be stably maintained by the housing fastening part 160.

[0096] In the illustrated embodiment, the temperature measuring mechanism 10 includes a housing 100, a cable winding portion 200, and a sliding prevention portion 400.

[0097] The housing 100 forms the outer shape of the temperature measuring mechanism 10. A space is formed inside the housing 100. Other components of the temperature measuring mechanism 10, such as the cable winding section 200, can be accommodated in the space.

[0098] Additionally, the space can accommodate an optical cable C. The optical cable C can extend from the outside of the housing 100 into the interior space of the housing 100, and then extend back out of the housing 100.

[0099] At this time, the total length of the optical cable C located inside the housing 100 can be a predetermined length or more. In one embodiment, the predetermined length can be 30 cm. This allows for more accurate detection of temperature changes in the power line W.

[0100] The space of housing 100 is in communication with the outside. Optical cable C and power line W can be partially accommodated in the space of housing 100.

[0101] The housing 100 can be any shape capable of accommodating the optical cable C and connecting it to the power line W. In the illustrated embodiment, the housing 100 is formed as a quadrangular prism shape with a cross-section having a length in one direction (front-back direction) longer than that in the other direction (left-right direction) and a height in the vertical direction.

[0102] The housing 100 may be formed of an insulating material. This is to prevent damage from high-voltage current flowing in the power line W, or to prevent accidents that could arbitrarily expose the current to the outside.

[0103] The housing 100 may be formed of a lightweight and highly rigid material. The housing 100 is exposed to the outside to prevent damage from the external environment.

[0104] In one embodiment, the housing 100 may be formed of an insulating synthetic resin material.

[0105] The housing 100 can be assembled or disassembled by operators. Therefore, the housing 100 can be formed from a plurality of constituent elements.

[0106] In the illustrated embodiment, the housing 100 includes a first housing 110, a second housing 120, a cable through-hole 130, a power line through-hole 140, a housing joint 150, and a housing fastening part 160.

[0107] The first housing 110 and the second housing 120 are combined to form the outer shape of the housing 100.

[0108] The first housing 110 forms one side of the housing 100. In the illustrated embodiment, the first housing 110 forms the upper side of the housing 100.

[0109] The second housing 120 forms the other side of the housing 100. In the illustrated embodiment, the second housing 120 forms the lower side of the housing 100.

[0110] The first housing 110 and the second housing 120 can be joined together. That is, in Figure 1 In the illustrated embodiment, the first housing 110 and the second housing 120 are joined together so that no other components other than the power line W and the optical cable C are exposed to the outside.

[0111] exist Figure 2 In the illustrated embodiment, the first housing 110 and the second housing 120 are separated from each other, thereby exposing the interior space of the housing 100 to the outside. An operator can form the first housing 110 and the second housing 120 as follows: Figure 2 The temperature measuring mechanism 10 is connected to the power line W in the state shown.

[0112] The first housing 110 and the second housing 120 can be joined in a manner that exposes their internal spaces to the outside. Figures 1 to 3 In the illustrated embodiment, the first housing 110 and the second housing 120 are rotatably joined via a housing joint 150. In this embodiment, the first housing 110 and the second housing 120 can be hinged together.

[0113] Although not shown in the figures, the first housing 110 and the second housing 120 can be configured in a way that allows them to be completely separated from each other. That is, the temperature measuring mechanism 10 can be formed by the first housing 110 and the second housing 120, which are separated from each other, surrounding and connecting the electric field line W. In the embodiment described, the first housing 110 and the second housing 120 can be held together by means of magnets or the like.

[0114] like Figure 2 As shown, the first housing 110 and the second housing 120 can be formed symmetrically to each other with respect to the longitudinal direction of the housing 100, and the front-rear direction in the illustrated embodiment. This is because the electric field lines W housed inside the first housing 110 and the second housing 120 are formed with a circular cross-section.

[0115] Spaces are formed inside the first housing 110 and the second housing 120, respectively. Specifically, as... Figure 2 and Figure 3 As shown, a first space S1 is formed inside the first housing 110, and a second space S2 is formed inside the second housing 120.

[0116] The power line W and the optical cable C are partially housed in the first space S1 and the second space S2, respectively. The first space S1 and the second space S2 are interconnected, forming the internal space of the shell 100.

[0117] Therefore, it can be said that the power line W and the optical cable C are housed in the first space S1 and the second space S2.

[0118] The first space S1 and the second space S2 can be formed into shapes corresponding to the shapes of the first housing 110 and the second housing 120. In the illustrated embodiment, the first space S1 and the second space S2 extend further in the front-rear direction, similar to the shapes of the first housing 110 and the second housing 120.

[0119] The cable winding part 200 and the slip prevention part 400 can be accommodated inside the first space S1 and the second space S2. This will be described in detail later.

[0120] The cable through-hole 130 serves as a channel for the optical cable C to enter the internal space of the housing 100 from the outside, namely the first space S1 or the second space S2. The cable through-hole 130 connects the internal space of the housing 100 with the outside.

[0121] A cable through-hole 130 is formed through the outer peripheral surface of the housing 100. In other words, the cable through-hole 130 is formed through the surface of the housing 100 surrounding the first space S1 or the second space S2. The cable through-hole 130 connects the first space S1 or the second space S2 to the outside.

[0122] In the illustrated embodiment, cable through-holes 130 are formed on the front and rear sides of the housing 100, respectively. In other words, the cable through-holes 130 extend through the end face of the housing 100 in its extending direction, which is formed on the surface surrounding the first space S1 or the second space S2.

[0123] In the illustrated embodiment, the cable through-hole portion 130 is configured to allow the optical cable C to extend along the extension direction of the housing 100, i.e., the extension direction of the power line W, toward the first space S1 or the second space S2.

[0124] Alternatively, the cable through-hole 130 is formed in a direction different from the extension direction of the power line W, allowing the optical cable C to extend in said different direction. In the embodiment described, preferably, the optical cable C is configured to have sufficient curvature to prevent damage to the optical cable C.

[0125] Multiple cable through-holes 130 can be formed. The multiple cable through-holes 130 are formed at different positions and can function as channels for optical cables C to pass through.

[0126] In the illustrated embodiment, a pair of cable through-holes 130 are formed on the front and rear sides of the first housing 110 and the second housing 120, respectively, resulting in a total of eight, but the number can be varied.

[0127] A pair of cable through-holes 130, i.e., a pair of cable through-holes 130 formed on the front or rear side of the first housing 110 or the second housing 120, can be spaced apart from each other. In the illustrated embodiment, the pair of cable through-holes 130 can be arranged facing each other across a power line through-hole 140 through which the power line W passes.

[0128] Therefore, the optical cable C, extending into the interior space of the housing 100 through the cable through-hole 130, can be configured adjacent to the power line W. As a result, temperature changes in the power line W can be detected quickly and accurately.

[0129] In the illustrated embodiment, the cable through-hole portion 130 includes a guide groove 131, a receiving space 132, and a fixing protrusion 133. Figure 3 (Displays best).

[0130] The guide groove 131 connects the receiving space 132 to the outside. The optical cable C can pass through the guide groove 131 and move along the guide groove 131 to enter the receiving space 132.

[0131] The guide groove 131 extends in one direction, specifically in the vertical direction as shown in the illustrated embodiment. The guide groove 131 can extend through the outer peripheral surface of the housing 100 in any direction that connects the receiving space 132 to the outside.

[0132] In the illustrated embodiment, the guide groove 131 extends in a straight line. Alternatively, the guide groove 131 may include at least one bend or fold. In this embodiment, the optical cable C that passes through the guide groove 131 has a variable movement path, thereby preventing the optical cable C from detaching arbitrarily.

[0133] The cross-sectional area of ​​the guide groove 131 can be formed to be less than or equal to the cross-sectional area of ​​the optical cable C or the cross-sectional area of ​​the accommodating space 132.

[0134] Typically, the outer periphery of the optical cable C is formed of a flexible material, enabling it to undergo a predetermined shape deformation. Therefore, during its movement along the guide groove 131, the optical cable C stores restoring force through this predetermined shape deformation and can return to its original shape upon reaching the receiving space 132. In this embodiment, the optical cable C can be stably held in the receiving space 132.

[0135] The receiving space 132 is a space for accommodating the optical cable C that moves along the guide groove 131. The receiving space 132 extends through the outer peripheral surface of the housing 100.

[0136] The receiving space 132 is connected to the outside. Specifically, the receiving space 132 is connected to the outside through a guide slot 131. The optical cable C inserted into the guide slot 131 can be moved to the receiving space 132.

[0137] The accommodating space 132 can be any shape capable of stably accommodating the optical cable C. In the illustrated embodiment, the accommodating space 132 is formed as a disk shape with a circular cross-section and a height in the vertical direction. This is because, typically, the optical cable C is formed with a circular cross-section.

[0138] The cross-sectional area of ​​the accommodating space 132 can be formed to be greater than or equal to the cross-sectional area of ​​the optical cable C. This is so that even if the temperature measuring mechanism 10 shakes, the shaking of the optical cable C housed in the accommodating space 132 can be buffered to a specified extent.

[0139] A fixed protrusion 133 is provided on the outer peripheral surface of the enclosing space 132.

[0140] The fixed protrusion 133 presses down on and supports the outer periphery of the optical cable C housed in the housing space 132, preventing the optical cable C from detaching arbitrarily.

[0141] A fixing protrusion 133 is formed by protruding from the outer peripheral surface surrounding the receiving space 132 toward the receiving space 132. In the illustrated embodiment, the fixing protrusion 133 is located on the upper right side of the receiving space 132, but its position can be changed.

[0142] The fixing protrusion 133 can be configured adjacent to the portion that communicates with the guide groove 131 and the receiving space 132. The cross-sectional area of ​​the guide groove 131 is formed to be smaller than the cross-sectional area of ​​the receiving space 132, so the effect of preventing the optical cable C from detaching can be further improved by providing the fixing protrusion 133.

[0143] The fixing protrusion 133 can be any shape capable of stably maintaining the position of the optical cable C. In the illustrated embodiment, the fixing protrusion 133 can be arc-shaped to protrude into the receiving space 132, but its shape can be changed to a triangle, quadrilateral, or other polygon or ellipse.

[0144] The power line through-hole 140 functions as a channel for the power line W to enter the internal space of the housing 100. The power line through-hole 140 connects the internal space of the housing 100 with the outside.

[0145] The power line through-hole 140 can be any shape through which the power line W passes. In the illustrated embodiment, the cross-section of the power line through-hole 140 is circular, but it can be varied according to the cross-sectional shape of the power line W.

[0146] The power line through-hole 140 may be formed through any one or more of the surfaces surrounding the interior space. In the illustrated embodiment, the power line through-hole 140 is formed on the front side and the rear side.

[0147] A plurality of power line through-holes 140 may be formed. The plurality of power line through-holes 140 may be formed at different locations. In the illustrated embodiment, the power line through-holes 140 include a first power line through-hole 141 formed in the first housing 110 and a second power line through-hole 142 formed in the second housing 120.

[0148] A plurality of first power line through-holes 141 may be provided. The plurality of first power line through-holes 141 may be formed in different portions of the first housing 110. In the illustrated embodiment, the first power line through-holes 141 are respectively formed on the front side and the rear side of the first housing 110. The plurality of first power line through-holes 141 are arranged facing each other across a first space S1.

[0149] In an embodiment where the power line through-hole portion 140 has a circular cross-section, a pair of first power line through-hole portions 141 facing each other can be configured to have the same central axis.

[0150] A plurality of second power line through-holes 142 may be provided. The plurality of second power line through-holes 142 may be formed in different portions of the second housing 120. In the illustrated embodiment, the second power line through-holes 142 are respectively formed on the front side and the rear side of the second housing 120. The plurality of second power line through-holes 142 are arranged facing each other across the second space S2.

[0151] In an embodiment where the power line through-hole portion 140 has a circular cross-section, a pair of power line through-hole portions 142 facing each other can be configured to have the same central axis.

[0152] With the first housing 110 and the second housing 120 combined, the first power line through-hole 141 and the second power line through-hole 142 can communicate with each other to form the power line through-hole 140.

[0153] exist Figure 1 and Figure 3In the illustrated embodiment, the power line through-hole 140 is formed with a circular cross-section. In the same embodiment, the first power line through-hole 141 and the second power line through-hole 142 can be formed as arc shapes with the same curvature and radius on their outer periphery.

[0154] The housing joint 150 allows the first housing 110 and the second housing 120 to be engaged in a manner that enables relative movement. The first housing 110 and the second housing 120 can change their relative positions while remaining engaged with each other.

[0155] The housing joint 150 is respectively joined to the first housing 110 and the second housing 120. Figure 2 In the illustrated embodiment, the housing joint 150 allows the first housing 110 and the second housing 120 to be joined in a manner that enables them to rotate relative to each other. In this embodiment, the housing joint 150 may be constituted by a hinge member.

[0156] The housing joint 150 may be provided in a plurality of ways. The plurality of housing joints 150 may be joined to the first housing 110 and the second housing 120 at different positions.

[0157] exist Figure 2 In the illustrated embodiment, two housing joints 150 are provided and are spaced apart from each other in the front-rear direction of the housing 100 extending in the illustrated embodiment.

[0158] The shape, number, and configuration of the housing joint 150 can be changed according to the environment in which the temperature measuring mechanism 10 is installed.

[0159] The housing fastening part 160 keeps the first housing 110 and the second housing 120 in contact with each other. In other words, the housing fastening part 160 keeps the first space S1 and the second space S2 in an adjacent configuration and connected to each other and surrounded by the housing 100.

[0160] The housing fastener 160 can be provided on either the first housing 110 or the second housing 120. Figure 2 In the embodiment shown, the housing fastener 160 may be provided on both the first housing 110 and the second housing 120.

[0161] A plurality of housing fasteners 160 may be provided. The plurality of housing fasteners 160 may be arranged in different positions relative to each other. Any one of the plurality of housing fasteners 160 may be engaged with another.

[0162] exist Figure 2In the illustrated embodiment, the housing fastening portions 160 provided on the first housing 110 are spaced apart from each other in the front-rear direction in the extending direction of the housing 100. The housing fastening portions 160 provided on the second housing 120 are also spaced apart from each other in the front-rear direction in the extending direction of the housing 100.

[0163] The housing fasteners 160 can be formed in any shape that allows them to be joined together by external force and remain joined, and can be separated again by external force.

[0164] In one embodiment, the housing fastening part 160 may be composed of a magnetic component that uses electromagnetic attraction to maintain the combined state of the first housing 110 and the second housing 120.

[0165] In another embodiment, the housing fastener 160 may be configured as a snap fit or a forced clamping connection.

[0166] The cable winding section 200 winds up the optical cable C that extends toward the interior space of the housing 100. The optical cable C is wound around the cable winding section 200 so that it will not unravel arbitrarily within the interior space of the housing 100.

[0167] That is, the cable winding section 200 functions as a reel for winding the optical cable C.

[0168] Furthermore, the cable winding portion 200 supports the power line W extending into the interior space of the housing 100. Specifically, the cable winding portion 200 partially supports the outer periphery of the power line W that passes through the housing 100. This ensures that the temperature measuring mechanism 10 and the power line W are stably connected.

[0169] The cable winding portion 200 is attached to the housing 100. Specifically, the cable winding portion 200 is disposed in a space formed inside the housing 100. One side of the cable winding portion 200 is attached to one side of the housing 100 surrounding the space, and the other side of the cable winding portion 200 is disposed spaced apart from the aforementioned side of the housing 100.

[0170] A plurality of cable winding sections 200 may be provided. The plurality of cable winding sections 200 may be configured to be arranged at different positions and to wind the optical cable C separately.

[0171] exist Figure 2 In the embodiment shown, a pair of cable winding portions 200 are provided in the first housing 110 and a pair are provided in the second housing 120, for a total of four.

[0172] A pair of cable winding portions 200 disposed in the first housing 110 are spaced apart from each other in the front-rear direction in the extending direction of the housing 100, as shown in the illustrated embodiment. A pair of cable winding portions 200 disposed in the second housing 120 are also spaced apart from each other in the front-rear direction in the extending direction of the housing 100, as shown in the illustrated embodiment.

[0173] At this time, as described later, the cable winding portion 200 can be configured such that the center of the support member 220 and the center of the power line through-hole portion 140 are located on the same axis.

[0174] In the illustrated embodiment, the cable winding portion 200 includes a column member 210 and a support member 220.

[0175] The column member 210 is the part where the cable winding portion 200 is joined to the housing 100. The column member 210 is joined to one side of the housing 100. The column member 210 extends into the interior space of the housing 100.

[0176] As described above, a plurality of cable winding portions 200 are provided, and can be respectively coupled to the first housing 110 and the second housing 120.

[0177] Reference Figure 2 The column member 210, which is coupled to the first housing 110, partially surrounds one side of the first space S1, and in the illustrated embodiment, the top surface is coupled to the first housing 110. The column member 210 extends from said side of the first housing 110 to the first space S1.

[0178] Additionally, the column member 210, which is coupled to the second housing 120, partially surrounds one side of the second space S2, specifically the bottom surface in the illustrated embodiment. The column member 210 extends from said side of the second housing 120 into the second space S2.

[0179] At this time, the extension length of the column member 210 can be determined based on the distance between the support members 220 facing each other when the first housing 110 and the second housing 120 are combined.

[0180] That is, refer to Figure 3 A power line through-hole 140 for accommodating the power line W is disposed between the opposing support members 220. The column member 210 may extend such that the distance between the opposing support members 220 is greater than or equal to the diameter of the power line W. In other words, in one embodiment, the column member 210 may extend such that the distance between the ends of the opposing column members 210 is greater than or equal to the diameter of the power line W.

[0181] Therefore, the power line W is located between the power line through-hole portion 140 and a pair of cable winding portions 200 arranged facing each other, so that it can be stably supported by the cable winding portions 200.

[0182] The optical cable C is wound around the column member 210. At this time, the optical cable C, which extends into the interior space of the housing 100 through any one of the cable through-holes 130, can be wound around any one of the plurality of column members 210 and then extend to another column member 210.

[0183] Repeating the above process, a single optical cable C can be wound around each of the plurality of column members 210, and can extend outwards through the cable through-hole portion 130 after extension. Therefore, the optical cable C is supported by the plurality of column members 210, thereby preventing the optical cable C from tangling or becoming entangled in the internal space of the housing 100.

[0184] At this point, the optical cable C extends in various ways and can be wound around each of the plurality of column members 210.

[0185] exist Figure 2 In the illustrated embodiment, the optical cable C extends into the first space S1 of the first housing 110 through a cable through-hole 130 located on the rear side of the first housing 110. The optical cable C extends after being wound around a column member 210 located on the opposite rear side, and is wound again around a column member 210 located on the front side.

[0186] Next, the optical cable C extends into the second space S2 of the second housing 120. Figure 2 The image shows the optical cable C extending across the walls of the first housing 110 and the second housing 120. Alternatively, additional components may be provided to form the extension path of the optical cable C.

[0187] The optical cable C extending to the second space S2 extends after being wound around the column member 210 located on the front side, and is wound around the column member 210 located on the rear side again. The optical cable C wound around all the column members 210 extends to the outside of the housing 100 through the cable through-hole portion 130 formed on the rear side of the second housing 120.

[0188] The extension configuration of the optical cable C can be changed. For example, the optical cable C can extend by alternately passing through the first space S1 and the second space S2. Alternatively, the optical cable C can be alternately wound multiple times around each pair of column members 210 of either the first housing 110 or the second housing 120, and then alternately wound multiple times around each pair of column members 210 of the other housing.

[0189] The optical cable C can be extended in any manner that allows it to extend sufficiently within the interior space of the housing 100 to be configured adjacent to the power line W and to detect the temperature of the power line W. In one embodiment, as described above, the sufficient length is 30 cm or more.

[0190] The column member 210 can be any shape that allows the optical cable C to be wound. Figure 4 In the illustrated embodiment, the column member 210 is a cylindrical shape formed by having a circular cross-section in the horizontal direction and extending in the vertical direction. In this embodiment, the lower end of the column member 210 is connected to the housing 100, and the upper end of the column member 210 is connected to the support member 220.

[0191] The support member 220 supports the power line W that passes through the housing 100. In addition, the support member 220 is configured to prevent the optical cable C wound on the column member 210 from detaching arbitrarily.

[0192] The support member 220 is combined with the column member 210. In the illustrated embodiment, the support member 220 is located at the end of the column member 210 opposite to the housing 100. In other words, the support member 220 is configured facing one side of the first housing 110 surrounding the first space S1, or facing one side of the second housing 120 surrounding the second space S2, through the column member 210.

[0193] The power line W is mounted on the support member 220. The support member 220 surrounds the outer periphery of the power line W, which is connected to the housing 100.

[0194] The support member 220 can be formed to have a shape corresponding to the outer periphery of the electric field line W. Figure 4 In the illustrated embodiment, the support member 220 is formed to include a curved portion because the electric field line W is formed into a cylindrical shape with a circular cross-section. In this embodiment, the curved portion included in the support member 220 can be centered on the same axis as the center of the electric field line through-hole 140. In other words, the curvature and radius of the curved surface included in the support member 220 can be determined accordingly to the curvature and radius of the electric field line through-hole 140.

[0195] The shape of the support member 220 can be changed according to the shape of the power line W.

[0196] The support member 220 is formed to have a larger cross-sectional area than the column member 210. Therefore, the movement of the optical cable C wound on the column member 210 in the direction toward the power line W is restricted by the support member 220, that is, the movement to the downward side in the case of the first housing 110 and the movement to the upward side in the case of the second housing 120 is restricted by the support member 220.

[0197] Therefore, the optical cable C wound around the column member 210 can maintain a stable wound state.

[0198] The support member 220 can be configured in any form that can support the power line W and prevent the coiled optical cable C from detaching arbitrarily.

[0199] The face of the supporting member 220 facing the electric field line W. Figure 4 In the embodiment shown, the upper side may be provided with a sliding prevention part 400.

[0200] The anti-slip part 400 maintains the contact state between the temperature measuring mechanism 10 and the power line W. The power line W, which passes through and is connected to the temperature measuring mechanism 10, can be held in a predetermined position by the anti-slip part 400 and will not slip.

[0201] The anti-slip part 400 can be configured to increase the friction between the cable winding part 200 and the power line W. Figure 4 In the embodiment shown, the sliding prevention part 400 is configured as a friction member 420.

[0202] In the embodiment described, the anti-sliding portion 400 covers one side of the support member 220, the top surface in the illustrated embodiment. This can be understood as the side of the support member 220 surrounding the outer periphery of the through-connected power line W.

[0203] The anti-slip part 400 can be configured as a separate component, and can be formed in a form that is integrated with the electric field line W. That is, in Figure 14 In the embodiment shown, the sliding prevention part 400 is formed as a clamp member 410 that is coupled to the electric field line W on the outer side of the housing 100 in the longitudinal direction.

[0204] In the embodiment described, a plurality of anti-sliding parts 400 are provided, and the housing 100 is fixedly located in the longitudinal direction between them.

[0205] It is understood that the anti-sliding part 400 can be applied not only to the temperature measuring mechanism 10 in this embodiment, but also to the temperature measuring mechanisms 20 and 30 in another embodiment and yet another embodiment.

[0206] (2) Description of the temperature measuring mechanism 20 according to another embodiment of the present invention

[0207] Reference Figures 5 to 6 The figure shows a temperature measuring mechanism 20 according to another embodiment of the present invention.

[0208] Compared with the temperature measuring mechanism 10 of the above embodiment, the temperature measuring mechanism 20 of this embodiment differs in the bonding and support structure of the optical cable C and the support structure of the power line W.

[0209] Therefore, referring to the accompanying drawings, the temperature measuring mechanism 20 of this embodiment will be described with a focus on the differences from the temperature measuring mechanism 10 of the above embodiment.

[0210] In the illustrated embodiment, the temperature measuring mechanism 20 includes a housing 100 and a cable pad 300.

[0211] The housing 100 of the temperature measuring mechanism 20 in this embodiment is similar in function and shape to the temperature measuring mechanism 10 in the above embodiment. That is, the first housing 110, the second housing 120, the cable through hole 130, the power line through hole 140, the housing joint 150, and the housing fastening part 160 provided in the housing 100 have the same shape and function as the various constituent elements of the housing 100 in the above embodiment.

[0212] However, the difference is that, in the case of the housing 100 in this embodiment, the cable pad 300 is disposed in the first space S1 and the second space S2.

[0213] The cable pad 300 is attached to the optical cable C to prevent the optical cable C from moving arbitrarily. In addition, the cable pad 300 restricts the optical cable C to remain in the position surrounding the power line W.

[0214] The cable pad 300 is housed within the interior space of the housing 100. Specifically, the cable pad 300 may be configured to surround the power line W within the interior space of the housing 100.

[0215] In the illustrated embodiment, the cable pad portion 300 includes a cable pad 310 and a pad support portion 320.

[0216] Reference Figure 6 The cable pad 310 is formed into a pad shape made of a flexible (elastic) material.

[0217] The optical cable C is inserted into the cable pad 310. At this time, since the cable pad 310 is formed of a flexible material, the cable pad 310 can deform its shape even when the optical cable C is inserted into it.

[0218] Furthermore, the cable pad 310 can be formed of a material with high frictional force with the contacting components. Therefore, the power line W supported by the cable pad 310 can be held in a predetermined position under the action of the frictional force of the cable pad 310.

[0219] In one embodiment, the cable pad 310 may be formed of silicon material.

[0220] The optical cable C can extend in various forms within the cable pad 310. In the illustrated embodiment, the optical cable C includes eight bends, changing direction and extending at least eight times.

[0221] The optical cable C can be extended in any form that ensures the required length for measuring the temperature of the power line W.

[0222] The cable pad 310 can be configured to be received within the interior space of the housing 100 and surround the power line W. Specifically, the cable pad 310 is disposed in the pad support portion 320 formed in the interior space of the housing 100.

[0223] Reference Figure 7 A pad support portion 320 is disposed within the internal space of the housing 100. The pad support portion 320 is the portion where the cable pad 310 is housed. In other words, the pad support portion 320 supports the cable pad 310.

[0224] A plurality of pad support portions 320 may be formed. The plurality of pad support portions 320 may be located in different spaces within the housing 100. In the illustrated embodiment, the pad support portions 320 are respectively formed in a first space S1 of the first housing 110 and a second space S2 of the second housing 120.

[0225] The pad support 320 can extend along the direction in which the housing 100 extends. Figure 5 In the embodiment shown, the pad support portion 320 extends in the front-to-back direction.

[0226] The pad support portion 320 can be formed to have a predetermined height. In this case, the pad support portion 320 extends in the vertical direction by a length shorter than the vertical length of the first housing 110 or the second housing 120.

[0227] Therefore, the upper end of the pad support 320 is located lower than the upper end of the first housing 110 or the second housing 120. The cable pad 310 can be disposed in the space formed by the aforementioned step. In one embodiment, the thickness of the cable pad 310 can be formed below the step.

[0228] The pad support portion 320 may comprise a plurality of portions having different shapes from each other. In the illustrated embodiment, the pad support portion 320 includes a first extension 321, a second extension 322, and a third extension 323 that are continuous with each other in a direction from the outside to the inside.

[0229] The first extension 321 is a portion of the cable pad 310. The first extension 321 is configured to surround the interior space of the housing 100 from one side in the width direction.

[0230] exist Figure 5In the illustrated embodiment, the first extension 321 is configured to surround the first space S1 of the first housing 110 or the second space S2 of the second housing 120 from the outside. That is, when the first housing 110 and the second housing 120 are open, the first extension 321 is located on the left side of the first space S1 and the right side of the second space S2, respectively.

[0231] The first extension 321 extends toward either the first space S1 or the second space S2. In the illustrated embodiment, the first extension 321 extends in a left-right direction. In this case, the first extension 321 can extend to a predetermined height.

[0232] The first extension 321 is positioned facing the third extension 323 across the second extension 322. In this case, the heights of the first extension 321 and the third extension 323 can be the same. Furthermore, the first extension 321 and the third extension 323 can be formed to have the same length in their width direction (i.e., the left-right direction in the illustrated embodiment).

[0233] The first extension 321 and the second extension 322 are continuous.

[0234] The second extension 322 extends from one side, Figure 5 In the illustrated embodiment, the lower side surrounds either the first space S1 or the second space S2. The second extension 322 extends between the first extension 321 and the third extension 323.

[0235] The second extension 322 can extend in the shape of a curved surface with a predetermined curvature. In the illustrated embodiment, the second extension 322 extends in a left-right direction and is arc-shaped to bulge downwards. The space formed by the shape of the second extension 322 can be defined as a first space S1 or a second space S2.

[0236] The second extension 322 and the third extension 323 are continuous.

[0237] The third extension 323 is configured to surround the interior space of the housing 100 from the other side in the width direction. Figure 5 In the illustrated embodiment, the third extension 323 is configured to surround the first space S1 or the second space S2 from the inside. That is, when the first housing 110 and the second housing 120 are open, the third extension 323 is located on the right side of the first space S1 and the left side of the second space S2, respectively.

[0238] Therefore, the pad support portion 320 is formed by including a first extension portion 321 and a third extension portion 323 with horizontal cross sections, and a second extension portion 322 that protrudes downward in an arc shape between them.

[0239] As described above, the cable pad 310 is formed of a flexible material and can be deformed. Therefore, it can be understood that after being placed on the first extension 321 and the third extension 323, the cable pad 310 can be deformed by being pressed against the second extension 322 by the power line W and disposed adjacent to the second extension 322.

[0240] (3) Description of the temperature measuring mechanism 30 according to another embodiment of the present invention

[0241] Reference Figures 7 to 8 The figure shows a temperature measuring mechanism 30 according to another embodiment of the present invention.

[0242] Compared with the temperature measuring mechanism 10 of the above embodiment, the temperature measuring mechanism 30 of this embodiment differs in the shape of the housing 100.

[0243] Therefore, referring to the accompanying drawings, the temperature measuring mechanism 30 of this embodiment will be described with a focus on the differences from the temperature measuring mechanism 10 of the above embodiment.

[0244] In the illustrated embodiment, the temperature measuring mechanism 30 includes a housing 100 and a cable winding portion 200.

[0245] Unlike the temperature measuring mechanism 10 in the above embodiment, the housing 100 in this embodiment is shaped like a cup or bell, similar to an insulating cap attached to an insulator I or similar component of a transformer T.

[0246] Therefore, the housing 100 of the temperature measuring mechanism 30 in this embodiment can replace the insulating cap, and while covering the insulator I, it can also measure the temperature of the power line W energized by the transformer T.

[0247] In the illustrated embodiment, the housing 100 includes a first housing 110, a second housing 120, a cable through-hole 130, a power line through-hole 140, a housing joint 150, and a housing fastening part 160.

[0248] The cable through-hole portion 130, power line through-hole portion 140, housing joint portion 150, and housing fastening portion 160 of this embodiment have the same structure and function as the cable through-hole portion 130, power line through-hole portion 140, housing joint portion 150, and housing fastening portion 160 of the above embodiment.

[0249] However, the housing 100 in this embodiment differs in shape from the first housing 110 and the second housing 120.

[0250] An opening for accommodating the insulator I is formed on one side of the first housing 110 and the second housing 120. Figure 8 In the illustrated embodiment, the opening is formed on the lower side of the first housing 110 and the second housing 120.

[0251] The opening, together with the cable through-hole 130 and the power line through-hole 140, connects the internal space of the housing 100, namely the first space S1 and the second space S2, to the outside.

[0252] Therefore, it is understood that the diameter of the opening is formed to be larger than the diameter of the insulator I.

[0253] As a result, it is understandable that the cross-sectional area of ​​the upper end of the housing 100 is formed to be smaller than the cross-sectional area of ​​the lower end of the housing 100 (i.e., the end in the direction of accommodating the insulator I).

[0254] 3. Explanation of the usage of temperature measuring mechanisms 10, 20, and 30 in embodiments of the present invention.

[0255] In the temperature measuring mechanisms 10, 20, and 30 of the various embodiments of the present invention described above, an electric field line W can be incorporated through and connected. An optical fiber C is arranged to surround the outer periphery of the incorporated electric field line W, and the pattern of light traveling along the optical fiber C can change accordingly to the temperature change of the electric field line W. Using the above principle, the temperature change of the electric field line W can be detected in real time and accurately.

[0256] The following is for reference Figures 9 to 15 The usage of the temperature measuring mechanisms 10, 20, and 30 in various embodiments of the present invention will be described in detail.

[0257] In the illustrated embodiment, the power line W is shown transparently for ease of understanding.

[0258] (1) Description of the usage of the temperature measuring mechanism 10 according to an embodiment of the present invention

[0259] The following is for reference Figures 9 to 10 This invention describes how to use the temperature measuring mechanism 10 according to an embodiment of the present invention.

[0260] The electric field line W runs through and is integrated into the temperature measuring mechanism 10, to be partially housed within the interior space of the housing 100. Figure 9 In the illustrated embodiment, the power line W is partially housed in the first space S1 of the first housing 110. Alternatively, it is understood that the power line W may also be partially housed in the second space S2 of the second housing 120.

[0261] At this time, each end of the power line W extending in the direction thereof, the front end and the rear end in the illustrated embodiment, are inserted into the first power line through hole 141 formed on the front and rear sides of the first housing 110.

[0262] The power line W is supported by the cable winding section 200. Figure 9 In the embodiment shown, the power line W is supported by support members 220 of two cable winding portions 200 disposed in the first space S1 of the first housing 110.

[0263] At this point, it can be understood that the optical cable C extends in the first space S1 and the second space S2 of the housing 100 and is partially wound around the column member 210 of the cable winding portion 200. Each end of the optical cable C in the extension direction is exposed to the outside through the cable through-hole portion 130.

[0264] If the first housing 110 or the second housing 120 is rotated toward each other while the electric line W is being contained, the connection between the temperature measuring mechanism 10 and the electric line W is completed.

[0265] like Figure 10 As shown, the outer periphery of the power line W is supported by the power line through-hole portion 140. At this time, a portion of the outer periphery of the power line W and other portions are also supported by the support member 220 of the cable winding portion 200.

[0266] exist Figure 10 In the illustrated embodiment, a portion of the upper outer periphery of the power line W and a portion of the lower outer periphery of the power line W are supported by the support member 220. In the illustrated embodiment, it can be understood that a portion of the upper outer periphery of the power line W is supported by a cable winding portion 200 disposed in the first housing 110, and a portion of the lower outer periphery of the power line W is supported by a cable winding portion 200 disposed in the second housing 120.

[0267] In addition, after the optical cable C extends through the cable through-hole 130 into the internal space of the housing 100, it extends again through the cable through-hole 130 to the outside of the housing 100.

[0268] Therefore, the temperature measuring mechanism 10 of this embodiment, by having a cable winding section 200, can not only wind the optical cable C and maintain a stable shape, but also stably support the power line W.

[0269] The first housing 110 and the second housing 120 are rotatably joined by a housing joint 150, thereby operable to open the internal space of the housing 100 for the placement of power lines W or optical cables C.

[0270] In addition, the first housing 110 and the second housing 120 can be operated to close the internal space of the housing 100 in order to accommodate the power line W or optical cable C housed in the internal space of the housing 100.

[0271] Furthermore, the first housing 110 and the second housing 120 can be stably maintained in a coupled state by the housing fastening part 160. At this time, as described above, the coupling state between the power line W and the temperature measuring mechanism 10 can be stably maintained by the sliding prevention part 400.

[0272] (2) Description of the usage of the temperature measuring mechanism 20 according to another embodiment of the present invention

[0273] The following is for reference Figures 11 to 12 The usage of the temperature measuring mechanism 20 according to another embodiment of the present invention will be explained.

[0274] The power line W passes through and is integrated into the temperature measuring mechanism 20, and is housed within the internal space of the housing 100. Figure 11 In the illustrated embodiment, the power line W is partially housed in the first space S1 of the first housing 110. Alternatively, it is understood that the power line W may also be partially housed in the second space S2 of the second housing 120.

[0275] At this time, each end of the power line W extending in the direction thereof, the front end and the rear end in the illustrated embodiment, are inserted into the first power line through hole 141 formed on the front and rear sides of the first housing 110.

[0276] Additionally, although not shown in the figure, the cable pad 310 of the cable pad portion 300 is disposed on the pad support portion 320. As described above, the cable pad 310 is formed of a flexible material.

[0277] Therefore, the cable pad 310 can be configured to contact the first extension 321, the second extension 322, and the third extension 323 of the pad support portion 320, which have different shapes from each other.

[0278] The power line W is contained within the cable pad 310 and supported by the pad support 320. In the illustrated embodiment, the power line W is supported by a second extension 322 of the pad support 320 disposed in the first space S1 of the first housing 110.

[0279] At this time, the optical cable C is contained within the cable pad 310 and housed together with the cable pad 310 in the internal space of the housing 100. It is understood that each end of the optical cable C extends to the outside through the cable through-hole 130.

[0280] If the first housing 110 or the second housing 120 is rotated toward each other while the electric line W is being housed, the connection between the temperature measuring mechanism 20 and the electric line W is completed.

[0281] like Figure 12 As shown, the outer periphery of the power line W is supported by the power line through-hole portion 140. At this time, a portion and other parts of the outer periphery of the power line W are also supported by the pad support portion 320 of the cable pad portion 300.

[0282] exist Figure 12In the illustrated embodiment, a portion of the upper outer periphery of the power line W and a portion of the lower outer periphery of the power line W are supported by the pad support portion 320. In the illustrated embodiment, it can be understood that a portion of the upper outer periphery of the power line W is supported by the pad support portion 320 disposed in the first housing 110, and a portion of the lower outer periphery of the power line W is supported by the pad support portion 320 disposed in the second housing 120.

[0283] In addition, after the optical cable C extends through the cable through-hole 130 into the internal space of the housing 100 in the state of being housed in the cable pad 310, it extends again to the outside of the housing 100 through the cable through-hole 130.

[0284] At this point, it is understood that the cable pad 310, which is combined with the optical cable C, is located between the power line W and the pad support 320.

[0285] Therefore, the temperature measuring mechanism 20 of this embodiment, by having a cable pad 300, can prevent the optical cable C from getting tangled and can also stably support the power line W.

[0286] The first housing 110 and the second housing 120 are rotatably joined by a housing joint 150, thereby operable to open the internal space of the housing 100 for the placement of power lines W or optical cables C.

[0287] In addition, the first housing 110 and the second housing 120 can be operated to close the internal space of the housing 100 in order to accommodate the power line W or optical cable C housed in the internal space of the housing 100.

[0288] Furthermore, the first housing 110 and the second housing 120 can be stably maintained in a coupled state by the housing fastening part 160. At this time, as described above, the coupling state between the power line W and the temperature measuring mechanism 20 can be stably maintained by the friction of the cable pad 310 itself or by the sliding prevention part 400.

[0289] (3) Description of the usage of the temperature measuring mechanism 30 according to another embodiment of the present invention

[0290] The following is for reference Figure 13 This describes the usage of the temperature measuring mechanism 30 according to another embodiment of the present invention.

[0291] The power line W passes through and is integrated into the temperature measuring mechanism 30, and is housed within the internal space of the housing 100. Figure 13 In the illustrated embodiment, the power line W is partially housed in the first space S1 of the first housing 110. Alternatively, it is understood that the power line W may also be partially housed in the second space S2 of the second housing 120.

[0292] At this time, one end of the power line W extending in the direction shown in the figure, the rear end in the illustrated embodiment, is inserted into the first power line through hole 141 formed on the rear side of the first housing 110.

[0293] Additionally, the other end of the power line W extending in the direction shown in the illustration, the front end, penetrates the opening formed on the front side of the first housing 110.

[0294] The power line W is supported by the cable winding section 200. Figure 13 In the embodiment shown, the power line W is supported by support members 220 of two cable winding portions 200 disposed in the first space S1 of the first housing 110.

[0295] At this point, it can be understood that the optical cable C extends in the first space S1 and the second space S2 of the housing 100 and is partially wound around the column member 210 of the cable winding portion 200. Each end of the optical cable C in the extension direction is exposed to the outside through the cable through-hole portion 130.

[0296] If the first housing 110 or the second housing 120 is rotated toward each other while the electric line W is being housed, the temperature measuring mechanism 30 and the electric line W are combined.

[0297] Once the temperature measuring mechanism 30 and the power line W are combined, the outer periphery of the power line W is supported by the power line through-hole portion 140. At this time, a portion of the outer periphery of the power line W and other portions can also be supported by the support member 220 of the cable winding portion 200.

[0298] A portion of the upper outer periphery of the power line W and a portion of the lower outer periphery of the power line W are supported by the support member 220. It can be understood that a portion of the upper outer periphery of the power line W is supported by the cable winding portion 200 provided in the first housing 110, and a portion of the lower outer periphery of the power line W is supported by the cable winding portion 200 provided in the second housing 120.

[0299] In addition, after extending through the cable through-hole 130 or the opening formed on the front side of the housing 100, the optical cable C extends into the interior space of the housing 100 and then extends outward through the cable through-hole 130 or the opening formed on the front side of the housing.

[0300] Therefore, the temperature measuring mechanism 30 of this embodiment, by having a cable winding section 200, can not only wind the optical cable C and maintain a stable shape, but also stably support the power line W.

[0301] The first housing 110 and the second housing 120 are rotatably joined by a housing joint 150, thereby operable to open the internal space of the housing 100 for the placement of power lines W or optical cables C.

[0302] In addition, the first housing 110 and the second housing 120 can be operated to close the internal space of the housing 100 in order to accommodate the power line W or optical cable C housed in the internal space of the housing 100.

[0303] Furthermore, the first housing 110 and the second housing 120 can be stably maintained in a coupled state by the housing fastening part 160. At this time, as described above, the coupling state between the power line W and the temperature measuring mechanism 30 can be stably maintained by the sliding prevention part 400.

[0304] Furthermore, in this embodiment, the housing 100 of the temperature measuring mechanism 30 is formed in the shape of a conventional insulating cup that is combined with the insulator I of the transformer T. Therefore, instead of a conventional insulating cup, it is possible to measure the temperature of the power line W connected to the transformer T while preventing the insulator I from being exposed to the outside.

[0305] (4) Explanation of the installation method of temperature measuring mechanisms 10, 20, and 30 in embodiments of the present invention

As described above, the temperature measuring mechanisms 10 and 20 are attached to the power line W while surrounding its outer periphery.

[0308] At this time, the clamp member 410 of the temperature measuring mechanism 10, 20 is provided with a sliding prevention part 400, so as to maintain the relative position with the power line W.

[0309] Reference Figure 15 The diagram shows the state in which the temperature measuring mechanisms 10, 20, and 30 of this embodiment are installed adjacent to the transformer T.

[0310] The temperature measuring mechanisms 10 and 20 in this embodiment of the invention are based on the premise of being installed on the power line W itself. Therefore, as Figure 15 As shown on the left, temperature measuring devices 10 and 20 are installed on the power line W connected to transformer T.

[0311] Although not shown in the figure, as described above, a clamping member 410 may be provided for maintaining the position of the temperature measuring mechanisms 10 and 20.

[0312] On the other hand, in another embodiment of the present invention, the temperature measuring mechanism 30 is based on the premise of being installed on the insulator I disposed on the transformer T. Therefore, as Figure 15As shown on the right, the temperature measuring mechanism 30 is connected to the power line W while simultaneously covering any one of the insulators I of the transformer T.

[0313] Therefore, the temperature measuring mechanisms 10, 20, and 30 of this embodiment of the invention can be installed near or separated from the power line W to detect the temperature of the power line W.
