Description

Technical Field

[0001] This application relates to the field of temperature detection technology, specifically to a temperature acquisition device. Background Technology

[0002] Temperature is a key parameter reflecting the operating status of various electrical equipment. Real-time monitoring of temperature changes at key locations is of great significance for preventing equipment overheating, insulation aging, circuit failures, and other issues.

[0003] Electrical equipment typically uses temperature sensing components that come into contact with critical locations to monitor their temperature. However, in the event of an anomaly such as a short circuit, the temperature at the critical location rises and a high current flows through it, which can easily cause the temperature sensing components in contact with the critical location to break down and fail. As a result, in the event of a fault, the temperature sensing components cannot effectively monitor the temperature at the critical location. Utility Model Content

[0004] This application provides a temperature acquisition device in which the temperature measuring component is directly connected to the conductive busbar to be monitored through a heat-conducting part to monitor the temperature of the conductive busbar. It has high sensitivity to changes in the temperature of the conductive busbar, which can improve the accuracy of temperature monitoring results. At the same time, it can also reduce the safety risks caused by the temperature measuring component directly contacting the live parts, and it can be easily disassembled and maintained, thus improving economic efficiency.

[0005] This application provides a temperature acquisition device, including a temperature measuring component, a fixing part, and a heat-conducting part. The fixing part and the heat-conducting part are both insulating components. The fixing part is used to connect and fix the heat-conducting part to the conductive busbar to be measured. The temperature measuring component is detachably connected to the heat-conducting part or the fixing part. In the connected state, the acquisition terminal of the temperature measuring component is connected to the heat-conducting part.

[0006] In some embodiments, the fixing part is provided with a mounting groove, the heat-conducting part is at least partially located in the mounting groove, and the side wall of the mounting groove opposite to the groove opening is provided with a through hole; the acquisition terminal is connected to the heat-conducting part at the through hole, or the acquisition terminal passes through the through hole and is connected to the heat-conducting part, or the heat-conducting part passes through the through hole and is connected to the acquisition terminal.

[0007] In some embodiments, the wall of the mounting groove, along the circumference of the perforation, is further provided with at least one of an annular protrusion and an annular groove.

[0008] In some embodiments, the fixing part is further provided with a fixing hole and is connected to the conductive busbar through a fixing member.

[0009] In some embodiments, the fastener is an insulating element.

[0010] In some embodiments, the fixing member is a conductive member, and the fixing part is further provided with at least one of a strip-shaped protrusion and a strip-shaped groove on the side surface facing the temperature measuring component, wherein the strip-shaped protrusion and the strip-shaped groove are spaced apart between the fixing hole and the through hole.

[0011] In some embodiments, the acquisition terminal is detachably connected to the heat-conducting part.

[0012] In some embodiments, the heat-conducting part includes a flexible heat-conducting element and a heat-conducting connector that are fixed and fitted together, the heat-conducting connector being connected to the flexible heat-conducting element, and the acquisition terminal being detachably connected to the heat-conducting connector.

[0013] In some embodiments, the flexible thermal conductive element and the fixed portion are respectively sandwiched on both sides of the thermal conductive connector.

[0014] In some embodiments, the thermally conductive connector is partially embedded in the flexible thermally conductive element, and the thermally conductive connector is partially exposed outside the flexible thermally conductive element and detachably connected to the acquisition terminal.

[0015] The temperature acquisition device provided in this application has the following technical advantages:

[0016] The heat-conducting part has good thermal conductivity. The acquisition terminal of the temperature sensing component is directly connected to the busbar through the heat-conducting part to monitor the temperature of the busbar. The temperature sensing component can effectively acquire the temperature of the busbar. Compared with a method that leaves a gap between the temperature sensing component and the busbar and calculates the temperature of the busbar by measuring the ambient temperature of the area near the busbar, the method of directly connecting the acquisition terminal to the busbar through the heat-conducting part to monitor the temperature of the busbar has higher sensitivity to changes in the temperature of the busbar, obtains more accurate monitoring results, and has higher reliability.

[0017] Furthermore, since both the heat-conducting part and the fixing part are insulating components, the temperature measuring component is not directly connected to the live parts (i.e., the busbar), which can provide protection for the temperature measuring component and prevent the high current of the busbar from causing the temperature measuring component to break down and fail. This also provides protection for the circuits, circuit boards, etc. connected to the temperature measuring component, so that the temperature acquisition device can still work normally and collect the temperature of the busbar in the event of abnormalities such as short circuits, thereby effectively monitoring the condition of the busbar.

[0018] Since the temperature measuring component is detachably connected to the fixing part or the heat-conducting part, when the temperature measuring component fails, it can be disassembled without disassembling the fixing part or the heat-conducting part, which facilitates maintenance and replacement and can effectively reduce costs.

[0035] To enable those skilled in the art to better understand the technical solutions of this application, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0036] Temperature is a key parameter reflecting the operating status of various electrical equipment. Real-time monitoring of temperature changes at critical locations is crucial for preventing equipment overheating, insulation aging, and circuit failures. This application provides a temperature acquisition device 10, which can be used to monitor the temperature of conductive busbars 20 (such as copper or aluminum busbars) at critical locations. If a short circuit or abnormality occurs in the conductive busbar 20, causing its temperature to rise, the temperature acquisition device 10 can detect the abnormality promptly, allowing for timely intervention and reducing further problems caused by short circuits or other abnormalities.

[0037] like Figure 1 and Figure 2 As shown, the conductive busbar 20 and the cable 30 are connected. The temperature acquisition device 10 is located on the conductive busbar 20. When the current input cable 30 is working, the current input to the conductive busbar 20 generates heat and causes its temperature to rise. The temperature of the conductive busbar 20 can be acquired by the temperature acquisition device 10.

[0038] like Figure 3 , Figure 4 and Figure 5 As shown, the temperature acquisition device 10 includes a temperature measuring component 1, a fixing part 2, and a heat-conducting part 3. The fixing part 2 and the heat-conducting part 3 are both insulating parts. The fixing part 2 is used to fix the heat-conducting part 3 to the conductive busbar 20 to be measured. The temperature measuring component 1 includes a acquisition terminal 11. The temperature measuring component 1 is detachably connected to the heat-conducting part 3, or the temperature measuring component 1 is detachably connected to the fixing part 2. When the temperature measuring component 1 is connected to the heat-conducting part 3 or the fixing part 2, the acquisition terminal 11 is connected to the heat-conducting part 3.

[0039] The fixing part 2 is used to connect and fix the heat-conducting part 3 to the conductive bus 20, so that in the fixed state, the heat-conducting part 3 is connected to the conductive bus 20, and the other side of the heat-conducting part 3 is connected to the collection terminal 11, thereby realizing heat transfer between the conductive bus 20 and the collection terminal 11.

[0040] In this context, "connection" can refer to physical contact without any mechanical connection between the two. In this case, separating the two would not require any other operation to disengage the mechanical connection or to overcome the force of the contact mechanical connection. "Connection" can also refer to the relative fixation of the two through a mechanical structure, such as a connection achieved through fasteners, riveting, etc.

[0041] The heat-conducting part 3 has good thermal conductivity. The acquisition terminal 11 of the temperature measuring component 1 is directly connected to the conductive busbar 20 through the heat-conducting part 3 to monitor the temperature of the conductive busbar 20. The temperature measuring component 1 can effectively acquire the temperature of the conductive busbar 20. Compared with a method that leaves a gap between the temperature measuring component 1 and the conductive busbar 20 and calculates the temperature of the conductive busbar 20 by measuring the ambient temperature of the area near the conductive busbar 20, the method of directly connecting the acquisition terminal 11 to the conductive busbar 20 through the heat-conducting part 3 to monitor the temperature of the conductive busbar 20 has higher sensitivity to temperature changes of the conductive busbar 20, thus obtaining more accurate monitoring results and higher reliability.

[0042] Furthermore, since both the heat-conducting part 3 and the fixing part 2 are insulating parts, the temperature measuring component 1 is not directly connected to the live part (i.e., the conductive bus 20), which can provide protection for the temperature measuring component 1 and prevent the high current of the conductive bus 20 from causing the temperature measuring component 1 to break down and fail. This also provides protection for the lines, circuit boards, etc. connected to the temperature measuring component 1, so that the temperature acquisition device 10 can still work normally and collect the temperature of the conductive bus 20 in the event of abnormalities such as short circuits, thereby effectively monitoring the condition of the conductive bus 20.

[0043] Since the temperature measuring component 1 is detachably connected to the fixing part 2 or the heat-conducting part, when the temperature measuring component 1 fails, the temperature measuring component 1 can be disassembled without disassembling the fixing part 2 or the heat-conducting part, which facilitates maintenance and replacement and can effectively reduce costs.

[0044] Temperature sensing component 1 may include an NTC (Negative Temperature Coefficient thermistor), which is a semiconductor device whose resistance decreases as temperature increases and is commonly used to monitor the temperature of critical parts in electrical equipment. In the connected state, the NTC's acquisition terminal 11 is connected to the heat-conducting part 3.

[0045] like Figure 5 and Figure 6 As shown, a mounting groove 22 is provided on the side of the fixing part 2 away from the temperature measuring component 1. The heat-conducting part 3 is at least partially located in the mounting groove 22. The heat-conducting part 3 is limited by the groove wall of the mounting groove 22, and the relative position between the two is stable. The heat-conducting part 3 can be stably connected to the conductive busbar 20, thereby enabling the heat-conducting part 3 to effectively transfer the heat of the conductive busbar 20 to the acquisition terminal 11 of the temperature measuring component 1, thus improving the accuracy of the temperature acquisition results.

[0046] Due to the installation slot 22, the heat-conducting part 3 is pre-installed into the installation slot 22 for pre-fixation during installation, and then the whole assembly can be assembled with the conductive busbar 20. The structure is simple and the operation is convenient.

[0047] The mounting slot 22 has a through hole 21 on the side wall opposite to the slot opening. The acquisition terminal 11 passes through the through hole 21 and is connected to the heat-conducting part 3. Alternatively, the heat-conducting part 3 passes through the through hole 21 at least partially and is connected to the acquisition terminal 11. Or, the acquisition terminal 11 and the heat-conducting part 3 are connected at the through hole 21.

[0048] The mounting slot can be as follows: Figure 6 The groove structure shown has groove walls along the circumference. When the heat-conducting part 3 includes a flexible heat-conducting element 31, during installation, the flexible heat-conducting element 31 can be a block structure that is directly pressed into the mounting groove 22, or it can be formed by pouring insulating thermally conductive adhesive into the mounting groove 22 and allowing the adhesive to solidify. This provides good flexibility. Alternatively, the mounting groove can also be a groove structure with at least two walls along the circumference, spaced apart from each other, such as a U-shaped groove or other groove structures where the side walls are not continuously arranged along the circumference.

[0049] The mounting groove 22 has at least one of an annular protrusion 23 and an annular groove along the circumference of the through hole 21 on its groove wall, which can be as follows: Figure 6 and Figure 7 The mounting groove 22 shown has an annular protrusion 23 on the side wall opposite to the groove opening. The annular protrusion 23 is arranged circumferentially along the through hole 21. Alternatively, the mounting groove 22 can have an annular groove on the side wall opposite to the groove opening, which is also arranged circumferentially along the through hole 21. Alternatively, the mounting groove 22 can have both an annular protrusion 23 and an annular groove on the side wall opposite to the groove opening. Alternatively, the mounting groove 22 can have at least one of the above-mentioned annular protrusion 23 and an annular groove on its side wall. Alternatively, the mounting groove 22 can have at least one of the above-mentioned annular protrusion 23 and an annular groove on its side wall opposite to the groove opening. At the same time, the mounting groove 22 can also have at least one of the annular protrusion 23 and an annular groove on its side wall.

[0050] The number of annular protrusions 23 and the number of annular grooves are not limited. There may be only one ring of annular protrusions 23, or there may be two or more rings of annular protrusions 23. There may be one ring of annular grooves, or there may be two or more rings of annular grooves.

[0051] The annular protrusion 23 and the annular groove can be arranged around the circumference of the through hole 21, which can increase the creepage distance from the conductive bus 20 to the acquisition terminal 11, effectively isolate the acquisition terminal 11 from the live body (conductive bus 20), so that the acquisition terminal 11 only acquires temperature. This achieves the goal of providing sufficient safety distance while reducing the volume of the fixing part 2, reducing the impact of short-circuit current on the temperature measuring component 1, and significantly compressing the overall size, which is convenient for miniaturization. It can also reduce the requirements for installation space, and has good flexibility and strong compatibility, thus adapting to more complex circuit scenarios.

[0052] The temperature acquisition device 10 can be used to acquire the temperature of the wiring busbar 20 of photovoltaic and other equipment. Due to limited installation space, by setting an annular protrusion 23 and an annular groove in the fixing part 2, the overall volume can be reduced while meeting the performance requirements, and the limitation on installation space can be reduced, making it highly adaptable.

[0053] like Figure 6 , Figure 7 and Figure 8 As shown, the fixing part 2 is also provided with a fixing hole 25. The fixing part 2 is fixed to the conductive bus 20 by the fixing member 4. This fixing can ensure the stability of the fixing part 2 and the conductive bus 20.

[0054] In this embodiment, the structure of the fixing member 4 is not limited. For example, the fixing member 4 can be a fixing bolt, the fixing hole 25 can be a through hole, and the conductive bus 20 has a mounting hole, which is a threaded hole. Alternatively, both the fixing hole 25 and the mounting hole can be through holes, and the fixing bolt can be fixed by a nut after passing through the fixing hole 25 and the mounting hole. Alternatively, the fixing member 4 can also be a snap-fit ​​member, with both the fixing hole 25 and the mounting hole being through holes. After the snap-fit ​​member passes through the fixing hole 25 and the mounting hole in sequence, it can snap-fit ​​with the other end face of the conductive bus 20 away from the temperature acquisition device 10. Alternatively, the conductive bus 20 can have a first snap-fit ​​member, and the fixing member 4 can have a second snap-fit ​​member. After the fixing member 4 passes through the fixing hole 25, it can be snap-fitted and fixed by the first snap-fit ​​member and the second snap-fit ​​member.

[0055] Of course, in this embodiment, there is no limitation on the fixing method between the fixing part 2 and the conductive bus 20. For example, the fixing part 2 may have extensions on both sides of its side edges, and the extensions on both sides may have flange structures that can be clamped and fixed from both sides of the conductive bus 20 in the width direction, so that the edge of the conductive bus 20 is clamped between the flange structure and the heat-conducting part 3. Alternatively, the extension may have a slot, and the conductive bus 20 may be clamped and fixed by the slot. Alternatively, the heat-conducting part 3 and the conductive bus 20 may be fixed by encapsulation, and the encapsulation layer may form the fixing part 2.

[0056] When the fixing part 2 is fixed to the conductive busbar 20 by the fixing member 4, the relative position between the fixing part 2 and the conductive busbar 20 can also be limited by the fixing member 4. For example, in the fixed state, due to the limitation of the fixing member 4, the position of the fixing part 2 in the length direction of the conductive busbar 20 is restricted, resulting in good stability. Furthermore, fixing by the fixing member 4 also facilitates disassembly and assembly operations, making it convenient for later maintenance and replacement operations.

[0057] The fastener 4 can be an insulating component, such as a plastic bolt or plastic clip, which is lightweight and has good insulation safety.

[0058] Fasteners can also be conductive, such as metal bolts and metal clips, which have high temperature resistance, good stability, and can extend service life while reducing costs.

[0059] like Figure 7 and Figure 8 As shown, the fixing part 2 is provided with two fixing holes 25 and is fixed to the conductive bus 20 by two fixing members 4. The two fixing holes 25 are roughly located on opposite sides of the fixing part 2 to ensure the stability of the fixing. Of course, in this embodiment, there is no limitation on the number of fixing members 4, such as one, three or more, and there is no limitation on the position of the fixing members 4.

[0060] like Figure 8 As shown, when the fixing member 4 is a conductive member, the surface of the fixing part 2 facing the temperature measuring component 1 is also provided with a strip groove 24, which is spaced between the fixing hole 25 and the through hole 21. Alternatively, the surface of the fixing part 2 facing the temperature measuring component 1 can be provided with a strip protrusion. The number of strip protrusions and strip grooves 24 is not limited. Of course, at least one strip protrusion and at least one strip groove 24 can be provided simultaneously between the fixing hole 25 and the through hole 21.

[0061] The shape of the strip-shaped protrusions and grooves 24 is not limited. Taking the groove 24 as an example, for instance... Figure 8 As shown, the strip groove 24 is a straight groove structure, or it can be set as an arc groove structure, or it can be set as an annular groove structure circumferentially arranged around the fixing hole 25 or the through hole 21. The line connecting the fixing hole 25 and the acquisition terminal 11 within a certain range (which can be a straight line or a curve) can intersect with the strip groove 24.

[0062] The strip-shaped protrusions and grooves 24 can increase the distance from the fixing hole 25 along the surface of the fixing part 2 to the through hole 21, and increase the creepage distance from the fixing member 4 to the acquisition terminal 11. This allows for the reduction of the volume of the fixing part 2 while providing sufficient safety distance, avoiding the impact of short-circuit current on the temperature measuring component 1, and significantly compressing the overall size, which facilitates miniaturization and reduces the requirements for installation space.

[0063] like Figure 8 As shown, the perforation 21 can be located at the center of the fixing part 2. The fixing part 2 can be provided with multiple sets of apex corners. Each set of apex corners includes two apex corners located on opposite sides of the fixing part 2. The fixing holes 25 are located at the two apex corners with the largest distance between them. Taking the fixing part 2 with a square cross-section as an example, the distance between the two apex corners located on the diagonal is the largest, and a fixing hole 25 is provided at each of the two apex corners with the largest distance. Taking the fixing part 2 with a rhomboid or elliptical cross-section as an example, the distance between the two vertices of the diagonal along the length direction is the largest.

[0064] When the fixing holes 25 are set at the two apex corners with the largest spacing, the distance between the fixing holes 25 and the through holes 21 can be increased while the fixing part 2 has the same size. This increases the creepage distance between the fixing part 4 and the acquisition terminal 11, thereby providing sufficient safety distance while keeping the fixing part 2 small in volume. This avoids short circuit current from affecting the temperature measuring component 1 and greatly reduces the overall size, making it easier to achieve miniaturization and reducing the requirements for installation space.

[0065] like Figure 8 As shown, the fixing part 2 is also provided with a clearance structure 26. The clearance structure 26 reduces the size and weight of the fixing part 2, and also reduces the probability of interference with other surrounding components during installation, thus facilitating installation. The specific structure, quantity, and position of the clearance structure 26 can be set according to the actual situation, and no specific restrictions are imposed here.

[0066] like Figure 8 As shown, at the two opposite corners of the fixing part 2 (the corners where the fixing holes 25 are not provided), a slit structure is provided and an avoidance structure 26 is formed there. The slit structure can be a plane or an arc surface.

[0067] In this embodiment, the connection method of the temperature measuring component 1 is not limited; it can be detachably connected to the fixing part 2 or detachably connected to the heat-conducting part 3. In this embodiment, the acquisition terminal 11 and the heat-conducting part 3 are detachably connected, and the two can be directly connected when connected, thereby simplifying the design requirements of the overall structure.

[0068] like Figure 9 As shown, the heat-conducting part 3 includes a flexible heat-conducting element 31 and a heat-conducting connector 32. The flexible heat-conducting element 31 and the heat-conducting connector 32 are fixed relative to each other and connected together. They can achieve good heat transfer effect. The acquisition terminal 11 is detachably connected to the heat-conducting connector 32.

[0069] The flexible thermally conductive component 31 can be a structure formed by flexible insulating and thermally conductive materials such as insulating thermally conductive adhesive, thermally conductive silicone pads, and thermally conductive foam. This flexible thermally conductive component 31 has a certain degree of flexibility. In the installed state, the flexible thermally conductive component 31 is sandwiched between the thermally conductive connector 32 and the conductive busbar 20, enabling good contact between the thermally conductive part 3 and the conductive busbar 20, improving the thermal conductivity, and thus improving the accuracy of temperature monitoring. The thermally conductive connector 32 facilitates a detachable connection with the acquisition terminal 11. The temperature measuring component 1 can directly use a conventional temperature measuring component 1 with an acquisition terminal 11, making it widely applicable.

[0070] In the installed state, the flexible heat-conducting component 31 is sandwiched between the conductive busbar 20 and the heat-conducting connector 32, and can also have a certain amount of compression, so that the flexible heat-conducting component 31 is stably connected to the conductive busbar 20 and the heat-conducting connector 32, which has good thermal conductivity and improves the accuracy of temperature acquisition results.

[0071] In this embodiment, the material of the thermally conductive connector 32 is not required. For example, metal connectors such as thermally conductive copper busbars and thermally conductive aluminum busbars can be used, which have good thermal conductivity. Ceramic connectors such as alumina connectors and zirconium oxide connectors can also be used.

[0072] In this embodiment, there are no restrictions on the fixing method between the flexible heat-conducting component 31 and the heat-conducting connector 32, such as... Figure 9 In the illustrated embodiment, the flexible heat-conducting element 31 and the fixing part 2 are respectively clamped on both sides of the heat-conducting connector 32, so that in the installed state, the heat-conducting connector 32 is relatively fixed to the flexible heat-conducting element 31 by clamping. This arrangement can improve structural stability while ensuring good fit between the flexible heat-conducting element 31 and the heat-conducting connector 32, improving thermal conductivity and thus improving the accuracy of temperature acquisition results.

[0073] When the fixing part 2 is provided with a mounting groove 22, and the heat-conducting part 3 is located within the mounting groove 22, such as Figure 9 As shown, the area of ​​the heat-conducting connector 32 is larger than the area of ​​the perforation 21. The circumferential edge of the side surface of the heat-conducting connector 32 away from the flexible heat-conducting component 31 can abut against the fixing part 2 along the circumferential direction of the perforation 21. This arrangement can simplify the overall structure and assembly process while satisfying the fixed stability and good heat conduction effect between the flexible heat-conducting component 31 and the heat-conducting connector 32.

[0074] Of course, in this embodiment, the heat-conducting connector 32 can also be partially embedded in the flexible heat-conducting component 31, and the two can be fixed by fitting together. For example, the edge of the heat-conducting connector 32 can be fixed by wrapping it in the flexible heat-conducting component 31, and the heat-conducting connector 32 can be partially exposed outside the flexible heat-conducting component 31 and detachably connected to the acquisition terminal 11.

[0075] Alternatively, the heat-conducting connector 32 can be fixed to the fixing part 2 by means of fasteners, snap-fit, etc., so that the heat-conducting connector 32 can be connected to the flexible heat-conducting part 31 in the fixed state.

[0076] The heat-conducting connector 32 and the acquisition terminal 11 can be connected by screws 5. For example, the acquisition terminal 11 and the heat-conducting connector 32 are respectively provided with connection holes and connected by screws 5 and nuts. Alternatively, the acquisition terminal 11 is provided with connection holes and the heat-conducting connector 32 is provided with threaded holes. The screws 5 can pass through the connection holes and be threaded into the threaded holes for connection.

[0077] Of course, in this embodiment, the heat-conducting part 3 can also be made of alumina heat-conducting components, aluminum nitride heat-conducting components, glass heat-conducting components (high thermal conductivity glass material), quartz sand heat-conducting components, etc., which have good insulation and thermal conductivity.

[0078] In the description of this application, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0079] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0080] The above are merely preferred embodiments of this application. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
