[0051] It should be noted that the modification of "one" and "multiple" mentioned in the present disclosure is illustrative rather than restrictive, and those skilled in the art should understand that unless the context clearly indicates otherwise, it should be understood as "one or more".

[0052] To solve the problems in the related art, the embodiment provides a transmission assembly, an electrical device and a power system.

[0053] As shown in Figure 1 , the transmission assembly provided by the first aspect of the present disclosure includes a transmission terminal 1 and a temperature measurement unit 4. The transmission terminal 1 has at least two conductive parts 1A for mounting different transmission cables 2. The temperature measurement unit 4 includes a plate body 41 and a temperature detection circuit arranged on the plate body 41. The plate body 41 is arranged corresponding to the at least two conductive parts 1A, and the plate body 41 is in thermal conductive connection with the at least two conductive parts 1A, respectively.

[0054] It should be understood that the conductive part 1A of the transmission terminal 1 is used to connect with at least one transmission cable 2, that is, each conductive part 1A can be used to connect with only one transmission cable 2. For example, one end of the conductive part 1A is used to form a first conductive connection part 11 described later, and the other end is connected with the internal circuit of the electronic device. Each conductive part 1A can also be used to connect with multiple transmission cables 2, such as Figure 1 As shown in the exemplary scheme, the transmission terminal 1 includes four conductive parts 1A, each of which has one first conductive connection part 11 (which can be more than one) and one second conductive connection part 12 (which can be more than one). The transmission cable 2 connected to the transmission assembly has two groups, one of which is connected to the four first conductive connection parts 11, and the other of which is connected to the four second conductive connection parts 12. The present disclosure will be described below based on this example.

[0055] Exemplarily, the transmission terminal 1 is an alternating current output terminal of an inverter, and the transmission terminal 1 has conductive parts 1A, for example, copper bars. The number of copper bars can also be set to be different according to the number of transmission cables 2 connected, and the number of copper bars is usually corresponding to the number of transmission cables 2. As shown in Figure 1 , one transmission cable 2 (i.e., a first transmission cable 21) is connected to the transmission terminal 1 along the X-axis direction and is electrically connected to one end (i.e., a first conductive connection part 11) of the copper bar in the transmission terminal 1, while the other transmission cable 2 (i.e., a second transmission cable 22) is connected to the transmission terminal 1 along the Z-axis direction and is electrically connected to the other end (i.e., a second conductive connection part 12) of the copper bar, thereby completing the electrical connection of the two transmission cables 2; as shown in Figure 1 , Figure 3 and Figure 4As shown, the end of the transmission cable 2 is provided with a conductive connecting piece (or conductive terminal), which is provided with an opening and is connected with the conductive part 1A of the transmission terminal 1.

[0056] It should be understood that the plate body 41 is arranged corresponding to at least two conductive parts 1A, so that the at least two conductive parts 1A to which it corresponds are in a state capable of being respectively in thermal connection with the plate body 41. On this basis, the position of the plate body 41 is not limited, and the conductive part 1A connected with the part of the transmission cable 2 and the plate body 41 can be arranged in parallel or vertically, which will be described in detail in the subsequent embodiments.

[0057] In the transmission assembly of the first embodiment of the present disclosure, the transmission terminal 1 has at least two conductive parts 1A for mounting different transmission cables 2, the plate body 41 of the temperature measuring unit 4 is arranged corresponding to the at least two conductive parts 1A, and the plate body 41 is respectively in thermal connection with the at least two conductive parts 1A, so that the temperature detection circuit of the temperature measuring unit 4 can feedback the temperature of the conductive part 1A corresponding to the plate body 41 by detecting the temperature of the plate body 41, thereby facilitating the timely discovery of the over-temperature condition of the circuit switching place caused by poor contact and the like through the detection of the temperature detection circuit, and improving the safety of the circuit switching place.

[0058] In the present embodiment, the same conductive part 1A has a first conductive connecting part 11 and a second conductive connecting part 12 corresponding to the electrical connection, and the first conductive connecting part 11 and the second conductive connecting part 12 are respectively used for connecting with different transmission cables 2.

[0059] Among them, the first conductive connecting part 11 of the at least two different conductive parts 1A is correspondingly provided with a plate body 41, and / or the second conductive connecting part 12 of the at least two different conductive parts 1A is correspondingly provided with another plate body 41.

[0060] As shown in Figure 1 and Figure 2 In the present disclosure, only the case that the first conductive connecting part 11 is correspondingly provided with a plate body 41 and the second conductive connecting part 12 is not correspondingly provided with a plate body 41 is shown. Specifically, the transmission cable 2 includes a first transmission cable 21 and a second transmission cable 22, and the first transmission cable 21 and the second transmission cable 22 are correspondingly arranged with the first conductive connecting part 11 and the second conductive connecting part 12, respectively. The first transmission cable 21 is mounted at the first conductive connecting part 11, and the second transmission cable 22 is mounted at the second conductive connecting part 12, the second conductive connecting part 12 is in conductive connection with the first conductive connecting part 11, and only the first conductive connecting part 11 is correspondingly provided with the mounting connecting piece 3 and the plate body 41 described later. The present disclosure will be described taking this as an example.

[0061] In this case, for ease of explanation, multiple first conductive connection portions 11 can be defined to be coplanar, such as... Figure 1 As shown, the plane can be understood as a plane parallel to the XY plane. The plate 41 is provided corresponding to at least two first conductive connection parts 11. The plate 41 can be provided parallel to the plane or perpendicular to the plane. The plate 41 can be arranged on the side of the first conductive connection part 11 facing the cable or on the side of the first conductive connection part 11 away from the cable.

[0062] It should be understood that in some schemes, multiple first transmission cables 21 can be independent of each other as needed, that is, they are not connected to each other; in other schemes, multiple first transmission cables 21 can be branched off from the same main cable as needed, or multiple second transmission cables 22 can be merged into the same main cable as needed. This specification will use the former as an example.

[0063] Optionally, the temperature measuring unit 4 also includes an electromagnetic shielding circuit. The electromagnetic shielding circuit is disposed on the plate 41. The plate 41 is provided with the electromagnetic shielding circuit, and multiple conductive structures are disposed between the plate 41 and the conductive part 1A. The electromagnetic shielding circuit is electrically connected to different conductive parts 1A through the multiple conductive structures respectively.

[0064] Electromagnetic shielding circuits can employ relevant technologies and may incorporate filtering components, such as capacitors.

[0065] Thus, the electromagnetic shielding circuit is electrically connected to the conductive part 1A of the transmission terminal 1 and the transmission cable 2. The board 41 with the electromagnetic shielding circuit can constitute the electromagnetic shielding board of the transmission component, ensuring the electromagnetic shielding performance of the transmission component, reducing the possibility of electromagnetic interference to the internal components of the electrical equipment caused by the electromagnetic field generated by the current transmission, and the structure of the transmission component is relatively compact, occupying less space, which is conducive to the lightweight design of the electrical equipment.

[0066] Optionally, the plate 41 is disposed opposite to the conductive part 1A, and multiple heat-conducting structures are provided between the plate 41 and the conductive part 1A. The plate 41 is heat-conductingly connected to different conductive parts 1A through the multiple heat-conducting structures.

[0067] like Figure 1 As shown, by way of example, the plate 41 is located above the first conductive connection portion 11 and is disposed opposite to the first conductive connection portion 11. The plate 41 and each conductive portion 1A are respectively thermally connected through different thermally conductive structures.

[0068] The specific arrangement of the heat-conducting structure is not limited, as long as it can conduct heat between the plate 41 and the first conductive connection portion 11. Examples will be provided later.

[0069] Thus, the plate body 41 is arranged opposite to the first conductive connecting part 11, and when the first conductive connecting part 11 is connected with the first transmission cable 21, the space left between the plate body 41 and the first conductive connecting part 11 can facilitate heat dissipation of the connection part between the first conductive connecting part 11 and the first transmission cable 21 to a certain extent; meanwhile, the heat conduction structure can better realize heat transfer from the first conductive connecting part 11 to the plate body 41, and can ensure the accuracy of temperature feedback from the temperature detection circuit of the plate body 41 to the temperature of the first conductive connecting part 11 to a certain extent.

[0070] Further, the space between the plate body 41 and the conductive part 1A is used to arrange the transmission cable 2 corresponding to the conductive part 1A.

[0071] Here, the connection mode of the first transmission cable 21 and the first conductive connecting part 11 is not limited, for example, the first transmission cable 21 and the plate body 41 can be fixed by fasteners respectively, and of course, they can also share a fixing structure, for example, share the mounting connecting piece 3 described later for fixing, which will be described in detail later.

[0072] Thus, the spatial structure of the transmission assembly is compact and has high reliability.

[0073] Optionally, the transmission assembly further comprises a mounting connecting piece 3, the plate body 41 is connected with the corresponding conductive part 1A through the mounting connecting piece 3, and the mounting connecting piece 3 is used to form a heat conduction structure between the plate body 41 and the conductive part 1A.

[0074] As shown in Figure 1 , it shows that the number of mounting connecting pieces 3 is consistent with the number of first conductive connecting parts 11, and the mounting connecting pieces 3 can realize heat transfer between the first conductive connecting parts 11 and the plate body 41 while realizing the installation of the plate body 41 on the transmission terminal 1. The heat conduction of the mounting connecting piece 3 can be realized by the material selection, for example, a metal piece can be used, which will not be described in detail here.

[0075] In a further optional solution of the mounting connecting piece 3, the mounting connecting piece 3 is also used to mount the transmission cable 2 on the corresponding conductive part 1A.

[0076] Thus, the mounting connecting piece 3 can realize the position fixation of the plate body 41 and the position fixation of the transmission cable 2, and can reduce the number requirement of connecting parts.

[0077] It should be understood that in this case, the mounting connecting piece 3 can also be used to form a conductive structure between the electromagnetic shielding circuit and the corresponding conductive part 1A, avoiding arranging an additional conductive structure, which is beneficial to the lightweight design of the transmission assembly.

[0078] As shown in Figures 3 to 5As shown, in the further optional solution of the mounting connector 3, the mounting connector 3 comprises a connector 31 and a fixing column 32; the fixing column 32 has oppositely arranged first and second ends 321 and 322, the second end 322 is connected with the transmission terminal 1 at the conductive part 1A; the connector 31 is connected with the first end 321, and the connector 31 cooperates with the clamping plate body 41.

[0079] Exemplarily, the first end 321 of the fixing column 32 is provided with a connecting hole 323, the connector 31 is a screw, the screw can pass through the mounting hole provided on the plate body 41 and then pass into the connecting hole 323, the connecting hole 323 is provided with a screw thread, which can engage with the screw, and the screw nut of the screw is clamped with the edge of the opening of the connecting hole 323 to clamp the plate body 41.

[0080] Thus, on the basis of heat conduction through the mounting connector 3, the position of the plate body 41 can be fixed through the fixing column 32 and the connector 31, which is simple in structure and strong in practicability.

[0081] In the embodiment, further, the interval between the plate body 41 and the conductive part 1A is used to arrange the transmission cable 2, and the transmission cable 2 can also be mounted on the transmission terminal 1 through the mounting connector 3.

[0082] Exemplarily, the fixing column 32 of the mounting connector 3 is arranged in the opening of the conductive connector of the first transmission cable 21, and the mounting connector 3 presses the first transmission cable 21 along the axial direction of the fixing column 32 to the first conductive connection part 11.

[0083] In the embodiment, further, as shown, Figure 3 the mounting connector 3 further comprises a pressing part 33, the pressing part 33 is connected with the fixing column 32, and the pressing part 33 is arranged in an interval with the first end 321; in the axial direction of the fixing column 32, the mounting connector 3 presses the transmission cable 2 to the conductive part 1A of the transmission terminal 1 through the pressing part 33.

[0084] Thus, as shown, Figure 3 and Figure 4 the connector 31, the fixing column 32 and the pressing part 33 are arranged to form the mounting connector 3, wherein the fixing column 32 is mounted on the transmission terminal 1 to realize the connection between the mounting connector 3 and the transmission terminal 1, the connector 31 is connected with the fixing column 32 and can cooperate with the clamping of the plate body 41 to effectively ensure the installation stability of the plate body 41 on the transmission terminal 1; on this basis, the pressing part 33 can cooperate with the transmission terminal 1 to clamp the transmission cable 2, thereby realizing the installation and fixation of the transmission cable 2 on the transmission terminal 1, and the pressing part 33 is connected with the fixing column 32, thereby ensuring the installation stability of the transmission cable 2 on the transmission terminal 1.

[0085] As shown, Figures 3 to 5As shown, in a further optional solution of the compression member 33, the compression member 33 is elastically arranged in the axial direction of the fixing column 32, the compression member 33 is provided with a through hole, and the compression member 33 is sleeved on the second end 322 through the through hole. The radial dimension of the first end 321 is greater than the radial dimension of the through hole.

[0086] As shown, the compression member 33 is an elastic structure, the radial dimension of the second end 322 is smaller than the radial dimension of the first end 321, a step is formed between the first end 321 and the second end 322, and the compression member 33 abuts against the step. Figure 5

[0087] In this optional embodiment, the second end 322 can penetrate into the opening of the conductive connecting member of the first transmission cable 21, and the conductive connecting member of the first transmission cable 21 is compressed on the first conductive connecting part 11 by the elasticity of the compression member 33.

[0088] In this case, the fixing column 32 can be detachably connected, for example, threaded, with the first conductive connecting part 11, and the compression force on the conductive connecting member of the first transmission cable 21 can be adjusted by the tightening degree of the fixing column 32. It should be understood that the cross-sectional shape of the fixing column 32 can be polygonal or circular, which is not limited.

[0089] Different from the case where the radial dimension of the first end 321 is greater than the radial dimension of the through hole, in the second embodiment of the present disclosure, as shown in Figure 6 and Figure 7 As shown, Figure 6 is a partial structure schematic view of the transmission assembly at the mounting connecting member in the second embodiment of the present disclosure (the area shown can be understood with reference to the area shown in Figure 3 , that is, the area circled by the letter A in Figure 1 , Figure 7 is an exploded partial structure schematic view of the transmission assembly at the mounting connecting member in the second embodiment of the present disclosure, the fixing column 32 has oppositely arranged first end 321 and second end 322, the first end 321 cooperates with the connecting member 31 to clamp the plate body 41, the second end 322 is connected with the transmission terminal 1, the compression member 33 is sleeved on the fixing column 32 and is in threaded engagement with the fixing column 32.

[0090] Specifically, as shown in Figure 7 , the fixing column 32 is a constant-diameter rotary structure, for example, a cylindrical structure, and can also be a variable-diameter rotary structure, for example, a circular truncated cone; the outer surface of the fixing column 32 is provided with external threads, and the compression member 33 is internally provided with internal threads; for example, the fixing column 32 is a threaded column, and the compression member 33 is a nut; the fixing column 32 can be fixedly installed on the transmission terminal 1, that is, fixedly connected with the outer shell of the transmission terminal 1 and fixedly connected with the copper bar in the transmission terminal 1; for example, the fixing column 32 is integrally formed with the transmission terminal 1, or the fixing column 32 is fixed on the transmission terminal 1 by welding or the like.​

[0091] Thus, the first end 321 can cooperate with the connector 31 to clamp the plate 41, achieving stable installation of the plate 41, while the second end 322 is connected to the transmission terminal 1 to ensure stable installation of the fixing post 32 at the transmission terminal 1. On this basis, the clamping member 33 is sleeved on the fixing post 32 and can engage with the fixing post 32 through threads. With this arrangement, by rotating the clamping member 33, the clamping member 33 can reciprocate between the first end 321 and the second end 322, and then cooperate with the transmission terminal 1 to clamp the transmission cable 2 when moving towards the second end 322, achieving stable installation of the transmission cable 2.

[0092] In the above embodiments, optionally, the temperature detection circuit includes a temperature detection element 42.

[0093] It should be understood that the location of the temperature sensing element 42 can be set according to actual needs. Generally, the location of the temperature sensing element 42 should not be too far away from the location of the mounting connector 3.

[0094] In this way, the temperature sensor can detect the temperature at locations such as near the mounting connector 3 on the board 41, thereby knowing the temperature changes of the internal conductive structures, such as the copper busbars, of the circuit junctions and transmission terminals 1. If the temperature is too high due to poor connection between the first transmission cable 21 and / or the second transmission cable 22 and the transmission terminal 1, it can be dealt with in time to avoid the transmission cable 2 and the transmission terminal 1 being burned due to excessive temperature, thus ensuring the working safety and stability of the electrical equipment.

[0095] like Figure 8 As shown, Figure 8 This is a partial structural diagram of the transmission component at the mounting connector and temperature sensing element in the third embodiment of this disclosure. It schematically shows the distribution of the temperature sensing element, and the area shown can be referenced. Figure 3 The area shown is, i.e. Figure 1 To further understand the area circled by the letter A, the mounting connector 3 has multiple components; a temperature sensing element 42 is provided on the vertical line connecting at least two adjacent mounting connectors 3.

[0096] It should be understood that, here, the temperature sensing element 42 may be approximately positioned on the perpendicular line of the line connecting two adjacent mounting connectors 3.

[0097] In some scenarios, the number of mounting connectors 3 corresponds to the number of first conductive connection parts 11. Multiple mounting connectors 3 are distributed sequentially, and a temperature detection element 42 is set at the center of the line connecting two adjacent mounting connectors 3.

[0098] Further, the mounting connectors 3 are provided in plurality; at least one of the mounting connectors 3 is provided with the temperature detecting element 42 at a preset distance range, and an upper limit of the preset distance range is less than or equal to a set value.

[0099] In this way, the corresponding temperature detecting requirement can be met, and the number of the temperature detecting elements 42 can be reduced, and the cost can be reduced.

[0100] As shown in Figure 3 , 6 , the temperature detecting element 42 can be provided in one-to-one correspondence with the mounting connector 3, and the set value can be set according to the actual situation.

[0101] For example, the distance between the set mounting connector 3 and the adjacent mounting connector 3 is greater than or equal to one-half of the set value.

[0102] For example, the distance between the set mounting connector 3 and the adjacent mounting connector 3 is greater than or equal to one-fourth of the set value.

[0103] In this case, the detection value of the temperature detecting element 42 can accurately reflect the temperature of the plate body 41 at the mounting connector 3, and the accuracy of temperature monitoring is relatively high.

[0104] As shown in Figure 1 and Figure 3 , the setting mode of the first conductive connecting part 11 is exemplarily described in combination with the specific embodiment. The transmission terminal 1 includes a mounting plate 111 and a protection plate 112, the mounting connector 3 is mounted on the mounting plate 111, the two protection plates 112 are parallel to each other and are spaced apart on the mounting plate 111, the plurality of first conductive connecting parts 11 are arranged on (for example, mounted on) the mounting plate 111 and located between the two protection plates 112, the first transmission cable 21, the mounting connector 3 and the plate body 41 are located between the two protection plates 112, and the projections of the first transmission cable 21, the mounting connector 3 and the plate body 41 are located at the protection plate 112 in the plane where the protection plate 112 is located.

[0105] Specifically, as shown in Figure 1 and Figure 3 , the plane where the protection plate 112 is located is the XZ plane, and the projections of the first transmission cable 21, the mounting connector 3 and the plate body 41 are located at the protection plate 112, i.e., the first transmission cable 21, the mounting connector 3 and the plate body 41 are inside the protection plate 112, and the height of the first transmission cable 21, the mounting connector 3 and the plate body 41 along the Z-axis direction is not higher than the height of the protection plate 112 along the Z-axis direction; as shown in Figure 3As shown, at least one support plate 113 is provided between the two protective plates 112. The support plate 113 is arranged parallel to the protective plates 112. The portion of the mounting plate 111 between the support plate 113 and the protective plate 112 is used to arrange the first conductive connection portion 11. The portion of the mounting plate 111 between adjacent support plates 113 is also used to arrange the first conductive connection portion 11. When the plate body 41 is placed between the two protective plates 112, the support plate 113 can abut against the plate body 41. When there is only one mounting connector 3 and one first transmission cable 21, both are located between the two protective plates 112. When there are multiple mounting connectors 3 and multiple first transmission cables 21, the first transmission cable 21 and the mounting connector 3 are located between the protective plate 112 and the support plate 113 or between the two support plates 113. The plate body 41 is connected to multiple mounting connectors 3.

[0106] The arrangement of the second conductive connection portion 12 is similar to that of the first conductive connection portion 11, and will not be described again here.

[0107] In this optional embodiment, two protective plates 112 are arranged parallel to each other and spaced apart on the mounting plate 111. The first transmission cable 21, the mounting connector 3, and the plate body 41 are all located between the two protective plates 112, thereby protecting the first transmission cable 21, the mounting connector 3, and the plate body 41 through the protective plates 112. At the same time, on the plane where the protective plates 112 are located, the projections of the first transmission cable 21, the mounting connector 3, and the plate body 41 are all located on the protective plates 112, that is, the first transmission cable 21, the mounting connector 3, and the plate body 41 are inside the protective plates 112, which plays an effective protective role. In addition, in some scenarios, such as Figure 12 and Figure 13 As shown, this also avoids interference between the first transmission cable 21, the mounting connector 3 and the board 41 and the chassis 5 when the first conductive connection part 11 is inserted into the chassis 5.

[0108] like Figure 9 As shown, unlike the scheme where the mounting connector 3 includes a connector 31 and a fixing post 32, in another alternative scheme of the mounting connector 3, the mounting connector 3 includes a first mounting member 34 and a second mounting member 35. The transmission cable 2 is mounted to the transmission terminal 1 through the first mounting member 34, and the board 41 is mounted to the transmission terminal 1 through the second mounting member 35.

[0109] Specifically, such as Figure 9As shown, the transmission cable 2 and the plate body 41 are respectively located on the opposite sides of the first conductive connecting part 11, that is, the transmission cable 2 and the plate body 41 are respectively located on the opposite sides of the mounting plate 111, the transmission cable 2 is connected with the first mounting part 34, and the plate body 41 is connected with the second mounting part 35, wherein the first mounting part 34 can be connected with the transmission terminal 1 and the second mounting part 35 in a matched manner, for example, the first mounting part 34 is a screw, and the second mounting part 35 is a nut; or the first mounting part 34 and the second mounting part 35 are independent structures and are respectively connected with the transmission terminal 1, for example, the first mounting part 34 and the second mounting part 35 are both screws, and the transmission terminal 1 is provided with mounting holes for the first mounting part 34 and the second mounting part 35 respectively.

[0110] As shown, the first conductive connecting part 11 of the transmission terminal 1 is conductively connected with the second conductive connecting part 12 through the copper bars inside the transmission terminal 1. Figure 1 and Figure 2 As shown, one end of the transmission terminal 1 extends in the reverse direction of the X axis to form the first conductive connecting part 11, and the other end of the transmission terminal 1 extends in the positive direction of the Z axis to form the second conductive connecting part 12, so that the transmission terminal 1 becomes an L-shaped structure. Figure 12 As shown, the first conductive connecting part 11 of the transmission terminal 1 can penetrate the wall plate 51 of the cabinet 5 accommodating the working element of the electrical equipment such as an inverter in the reverse direction of the X axis, and then enter the cabinet 5 to be electrically connected with the first transmission cable 21 connected to the working element, the plate body 41 with the electromagnetic shielding circuit is arranged inside the cabinet 5, and the second conductive connecting part 12 is left outside the cabinet 5 to be electrically connected with the second transmission cable 22 connected to other electrical equipment, wherein the transmission terminal 1 is fixedly installed on the wall plate 51 by screw connection or riveting.

[0111] As shown, Figure 1 and Figure 2 As shown, the first transmission cable 21 connected to the transmission terminal 1 and the second transmission cable 22 connected from the transmission terminal 1 can each have multiple.

[0112] As shown, Figure 10 and Figure 11 As shown in the fifth embodiment of the present disclosure, the number of the first conductive connecting part 11 and the number of the second conductive connecting part 12 of one transmission terminal 1 are equal and each have multiple, the copper bars inside the transmission terminal 1 have multiple groups, each group of copper bars has multiple copper bars, and each copper bar corresponds to complete the conductive connection between the first conductive connecting part 11 and the corresponding second conductive connecting part 12. Figure 10 It is shown that the first conductive connecting part 11 and the second conductive connecting part 12 are provided as two groups, in which case the two groups of first conductive connecting parts 11 are respectively provided with the plate body 41, and the two plate bodies 41 are arranged away from each other.

[0113] As shown, Figure 12And Figure 13 As shown, the wall plate 51 of the cabinet 5 has a through hole 511, the contour of the through hole 511 matches the outer contour of the first conductive connecting part 11, the first conductive connecting part 11 can pass through the hole 511 into the interior of the cabinet 5, and the stable installation of the transmission assembly of the first embodiment or the fifth embodiment of the present disclosure in the cabinet 5 is realized.

[0114] The electrical equipment provided by the embodiments of the present disclosure comprises the transmission assembly described above.

[0115] Referring to Figure 12 And Figure 13 The electrical equipment in the embodiments further comprises a cabinet 5, the cabinet 5 comprises a wall plate 51, the wall plate 51 is provided with a through hole 511, the transmission terminal 1 of the transmission assembly is arranged at the through hole 511 and connected with the wall plate 51, and the through hole 511 is at least used for the transmission cable 2 to pass through.

[0116] For example, the electrical equipment is an inverter.

[0117] The beneficial effects of the electrical equipment of the embodiments relative to the prior art are the same as those of the transmission assembly described above, which will not be repeated here.

[0118] Further, the end of the first conductive connecting part 11 is located inside or outside the cabinet 5, the end of the second conductive connecting part 12 of the transmission terminal 1 is located outside the cabinet 5, the through hole 511 is at least used for the transmission cable 2 (i.e. the first transmission cable 21) connected by the first conductive connecting part 11 to pass through, and the transmission terminal 1 is sealingly connected with the wall plate 51 at the through hole 511.

[0119] The sealingly connected manner of the transmission terminal 1 with the wall plate 51 at the through hole 511 is not limited. A sealing gasket can be arranged between the two.

[0120] In this case, leakage of the electrical equipment at the through hole 511 due to the arrangement of the transmission assembly can be avoided. Moreover, when the plate body 41 of the transmission assembly is arranged corresponding to at least two first conductive connecting parts 11 of the transmission terminal 1, and the plate body 41 is provided with an electromagnetic shielding circuit, electromagnetic shielding at the through hole 511 can be better achieved, separate shielding structures arranged at other positions are avoided, the occupied space is smaller, the structure is compact, and the practicability is strong.

[0121] In further optional cases, when the end of the first conductive connecting part 11 is located outside the cabinet 5, the plate body 41 corresponding to the first conductive connecting part 11 is arranged in parallel with the wall plate 51.

[0122] It should be understood that the parallel here can be approximate parallel, for example, an angle error of ±15° can be allowed.

[0123] Referring to Figures 14 to 16 As shown, Figure 14This is a partial structural diagram of the transmission component in another embodiment of the present disclosure. Figure 15 for Figure 14 The diagram shows the exploded structure of the transmission component. Figure 16 for Figure 14 The diagram shows a partial structural view of the transmission component installed at its mounting position behind the chassis. The transmission terminal 1 is recessed, forming the first conductive connection part 11. When the transmission terminal 1 is connected to the wall panel 51, the transmission terminal 1 and the through hole 511 of the wall panel 51 form a circumferential seal. The conductive connector of the first transmission cable 21 is angled, forming an L-shaped structure. The axial direction of the through hole on its conductive connector is approximately aligned with the axial direction of the through hole 511 on the wall panel 51. The plate body is approximately parallel to the wall panel 51. In this configuration, the transmission component occupies less internal space in the chassis 5, has a simple structure, and is highly practical. For example... Figure 14 In this scenario, the plate 41 can also cover the via 511 to a certain extent.

[0124] In a further alternative embodiment, when the end of the first conductive connection portion 11 is located inside the chassis 5, the plate 41 corresponding to the first conductive connection portion 11 is arranged parallel or perpendicular to the wall panel 51.

[0126] The arrangement in which the plate 41 is perpendicular to the wall panel 51 has been described in the previous section on embodiments of the transmission assembly. In this case, the axis of the through hole on the conductive connector of the first transmission cable 21 is substantially perpendicular to the axis of the through hole 511 on the wall panel 51.

[0127] It should be understood that plate 41 usually needs to be connected to other parts, and a suitable arrangement scheme for plate 41 can be selected according to the arrangement of other structures.

[0128] Optionally, in the above embodiments, the electrical equipment further includes at least one of a grounding structure and a control circuit, the temperature detection circuit of the temperature measuring unit 4 of the transmission component is electrically connected to the control circuit, and the electromagnetic shielding circuit of the temperature measuring unit 4 of the transmission component is electrically connected to the grounding structure.

[0130] For example, the signals detected by the temperature detection circuit of board 41 generally need to be transmitted to the control circuit inside the electrical equipment, which can then control the internal components. For instance, the control circuit can trigger an alarm based on the temperature detection results. It should be understood that the specific alarm strategy can be determined based on actual needs and testing.

[0131] In some scenarios in the above embodiments, the temperature detection circuit can include a digital display instrument to display the temperature value detected by the temperature detection element 42.

[0132] The power system provided in the embodiments of the present disclosure includes the transmission assembly described above, or includes the electrical device described above.

[0133] For example, the power system is a photovoltaic power generation system.

[0134] The power system of the present embodiment has the same beneficial effects as the transmission assembly described above or the electrical device described above relative to the prior art, and will not be described here.

[0135] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited to this. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the present disclosure.
