[0030] Embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although some embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments set forth herein. On the contrary, these embodiments are provided to more thoroughly and completely understand the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are only for exemplary purposes and are not used to limit the protection scope of the present disclosure.

[0031] In the description of the embodiments of the present disclosure, the term "including" and its like should be understood as an open inclusion, that is, "including but not limited to". The term "based on" should be understood as "at least partially based on". The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment". The term "some embodiments" should be understood as "at least some embodiments". There may also be other explicit and implicit definitions hereinafter. The terms "first", "second", etc. may refer to different or the same objects. There may also be other explicit and implicit definitions hereinafter.

[0032] As briefly mentioned above, regarding the problems of on-site wiring complexity and error risk, during the installation of traditional intelligent modules, users need to perform wiring on-site. These wiring requirements need to correspond the power wires and temperature measuring wires to the three-phase terminals one by one, which increases the complexity of installation. This complex wiring method greatly increases the risk of users connecting wires incorrectly. Incorrect wiring may not only cause the device to malfunction, but also pose safety hazards. In addition, regarding the temperature measurement accuracy problem, traditional temperature measuring sensors often have no direct or indirect contact with the copper bar terminals, resulting in a large error in temperature measurement and making temperature compensation difficult. Additionally, regarding the connection reliability problem, the unstable or unreliable connection between the temperature measurement and power extraction terminals and the copper bar of the external conducting wire may lead to inaccurate measurement data and even cause switchgear failures.

[0033] In addition, the communication components of traditional circuit breakers are often fixed integrally with the main structure of the monitoring module, resulting in the need to replace the entire module (such as the monitoring module and communication components) when the communication function needs to be upgraded or repaired, which increases the maintenance cost and difficulty. Additionally, traditional base plates usually require independent nut bases and fixing bolts, which not only increase the production cost but also make the assembly process complicated.

[0034] Therefore, these problems not only affect the assembly efficiency of switchgear but also reduce the reliability and safety of switchgear.

[0035] To solve or at least partially solve the above problems or other potential problems of the circuit breaker in the traditional solution, embodiments of the present disclosure provide a base plate assembly for switchgear and a switchgear solution. According to the solution of the embodiments of the present disclosure, the base plate assembly includes a base plate and a conductive temperature measuring component pre-installed on the base plate. Specifically, the base plate includes a first body and a plurality of first bases. The plurality of bases and the first body are of an integrally formed structure, and the plurality of first bases are respectively arranged at both ends of the first body. The first body includes a limiting post adjacent to the first base, and the first base includes a first fixing groove and a first receiving groove. The first fixing groove is used to accommodate a first nut.

[0036] Furthermore, the conductive temperature measuring component includes an annular end, a temperature measuring part, a conductive part, and a temperature sensor. The annular end is arranged at the axial end of the first fixing groove and is coupled to the first nut to couple the conductive wire to the annular end. The temperature measuring part is coupled to the annular end and forms a non-zero angle with the annular end, and the temperature measuring part is coupled in the first receiving groove. The temperature sensor is used to sense the temperature of the temperature measuring part. The conductive part is coupled to the end of the temperature measuring part away from the annular end and forms a non-zero angle with the temperature measuring part. The conductive part includes a limiting hole adapted to be sleeved on the limiting post. Thus, the base plate assembly realizes the organic combination of multiple functions such as conduction, temperature measurement, and fixing, which not only simplifies the installation process, reduces the risk of on-site wiring errors, but also improves the accuracy of temperature monitoring, thereby improving the safety and maintenance convenience of the circuit breaker.

[0037] Next, the exemplary structure of switchgear 100 will be described in conjunction with Figures 1 to 14 As shown, embodiments of the present disclosure provide a switchgear 100. The switchgear 100 includes a base plate assembly, a circuit breaker 120, a bottom case 130, and a communication component 140, forming an intelligent circuit breaker system that is easy to install and maintain. Figures 1 to 8

[0038] ​Specifically, the first base 113 on the base plate assembly is provided with a slideway 1131, which provides guidance for the installation of the base plate assembly and the bottom shell 130. The circuit breaker 120 is coupled with the slideway 1131 of the first base 113 of the base plate assembly through its first slide rail 1201, realizing simple and stable installation. This not only simplifies the assembly process but also ensures that the circuit breaker 120 can be accurately inserted and fixed on the base plate assembly. During this process, when the circuit breaker 120 is inserted in place, the annular end 1151 of the conductive temperature measuring component 115 on the base plate assembly will be accurately clamped between the first nut 114 of the base plate assembly and the first conductive part 1202 of the circuit breaker 120. This clamping relationship not only ensures a stable mechanical connection but also ensures a reliable electrical connection, and guarantees the stability of electrical performance and temperature measuring function. The base plate assembly will be described in detail below.

[0039] In other words, by using bolts to fasten the first nut 114 to the first conductive part 1202 of the circuit breaker 120, the annular end 1151 is pressed between the first conductive part 1202 and the first nut 114, thus forming a solid and reliable electrical circuit. This clamping connection method provides a better contact area, reduces the contact resistance, and improves the electrical performance of the switchgear 100.

[0040] Furthermore, the bottom shell 130 is coupled with the slideway 1131 of the base plate assembly through the second slide rail 1301. Similar to the installation method of the circuit breaker 120, the installation of the bottom shell 130 also realizes the clamping of the annular end 1151 of the conductive temperature measuring component 115, and the annular end 1151 is between the first nut 114 and the second conductive part 1302 inside the bottom shell 130. This not only ensures the reliability of the electrical connection but also improves the safety and stability of the entire switchgear 100.

[0041] Furthermore, the communication component 140 is detachably coupled to the bottom shell 130 and is electrically connected to the conductive temperature measuring component 115 and the circuit breaker 120 of the base plate assembly. Thereby, the flexibility of the detachable communication component 140 can be improved, facilitating future upgrade and maintenance work. For example, the communication component 140 may include a communication component using an HPLC module.

[0042] When it is necessary to upgrade, repair or replace the communication component 140, it can be removed from the bottom shell 130 without disturbing other components. Therefore, this not only simplifies the maintenance process but also reduces the maintenance cost and time, and at the same time reduces the risk of potential damage to the switchgear 100.

[0043] Secondly, the electrical connection between the communication component 140 and the conductive temperature measuring component 115 and the circuit breaker 120 of the base plate assembly can obtain temperature data and the status information of the circuit breaker 120 in real time, thereby realizing intelligent monitoring and remote control functions.

[0044] In addition, with the continuous development of communication technology, the communication component 140 can be replaced to adapt to new communication standards or new functions can be added without replacing the entire module.

[0045] As Figure 3 and Figure 4 shown, in some embodiments, the switching device 100 further includes a protection module 150. The protection module 150 can be flexibly arranged on one side of the circuit breaker 120 to allow adjustment according to different application scenarios and assembly environments, and can be selectively installed on the left or right side of the circuit breaker 120. By changing the assembly position of the protection module 150, the applicable range of the switching device 100 can be increased, enabling it to adapt to various complex installation environments and space limitations. For example, the protection module can adopt an N-pole module. The N-pole module can be used to handle the disconnection and connection of the neutral line.

[0046] The installation process of the protection module 150 adopts a slide rail structure similar to that of the circuit breaker 120 and the bottom case 130. It includes a third slide rail 1501 that matches the slideway 1131 of the first base 113 of the bottom plate assembly to ensure that the protection module 150 can be accurately inserted and fixed on the bottom plate assembly. This pluggable structure can enhance the modular characteristics of the switching device 100. In other words, this pluggable structure allows the protection module 150 to be disassembled and replaced when needed, facilitating the maintenance, upgrade, and troubleshooting of the switching device 100. In addition, this pluggable structure can facilitate function expansion, and different function protection modules 150 can be added or replaced according to needs without major modifications to the switching device 100.

[0047] In some embodiments, the protection module 150 includes a positioning portion. The positioning portion is coupled to a corresponding position on the first body 103 of the bottom plate assembly, thereby ensuring the accurate position and stability of the protection module 150 in the switching device 100.

[0048] Furthermore, the positioning portion can adopt a protrusion, a groove, or other special shapes that can match the preset corresponding structures on the bottom plate assembly. This precise coupling can ensure that the protection module 150 can be accurately positioned during installation, reducing installation errors and improving the assembly accuracy of the switching device 100. Secondly, the positioning portion enhances the stability of the protection module 150 during use, effectively preventing position deviation caused by vibration or external forces.

[0049] In addition, whether it is batch assembly on the production line or on-site maintenance and replacement, the positioning portion can ensure the same accuracy and position for each installation. This not only improves the quality consistency of the product but also simplifies the maintenance and replacement procedures.

[0050] In some embodiments, the positioning portion can also ensure the correct docking of the protection module 150 with other components (such as the circuit breaker 120, the communication component 140, etc.), ensuring the reliability of the electrical connection and the stability of the signal transmission.

[0051] As Figures 5 to 8 shown, in some embodiments, the bottom case 130 includes a second body and a plurality of second bases 1304 integrally formed with the second body, which can simplify the assembly process and also ensure the reliability and stability of the connection. The second base 1304 includes a second fixing groove 1306 for accommodating the second nut 1305 and a second receiving groove 1307 for accommodating the bolt at one end away from the bottom plate assembly. The bolt can pass through the second receiving groove 1307 from the side close to the bottom plate assembly and then be coupled to the second nut 1305 in the second fixing groove 1306. By changing the direction of the bolt coupling the second nut 1305, the length of the bottom case 130 can be reduced. In addition, through this connection method, the second conductive member 1302 can be reliably electrically connected to the first conductive member 1202 of the circuit breaker 120.

[0052] It should be noted that the direction of the bolt coupling on the first nut 114 is opposite to the direction of the bolt coupling on the second nut 1305. In other words, the bolt coupled on the first nut 114 is assembled from the end away from the bottom plate assembly, and the bolt coupled on the second nut 1305 is assembled from the end close to the bottom plate assembly.

[0053] In some embodiments, the second base 1304 of the bottom case 130 includes a guiding portion 1303. The guiding portion 1303 is configured on the side close to the bottom plate assembly to provide guidance for the precise docking of the bottom case 130 with the circuit breaker 120. This can not only simplify the assembly process but also improve the accuracy and efficiency of the assembly.

[0054] In addition, the circuit breaker 120 includes a receiving portion 1203 corresponding to the guiding portion 1303 of the second base 1304. The receiving portion 1203 cooperates with the guiding portion 1303 of the bottom case 130 to ensure that the bottom case 130 can be accurately and smoothly inserted into the circuit breaker 120. This "guide-receiving" pairing structure not only reduces the risk of errors during the installation process but also improves the structural stability of the entire switchgear 100.

[0055] In the following, the concept of the present disclosure will be described mainly based on the case of the bottom plate assembly. It should be understood that for the cases with other application bottom plate assemblies, it is similar, and will not be described separately hereinafter. For the convenience of description, the bottom plate assembly for the switchgear 100 in the embodiments of the present disclosure will be further elaborated hereinafter.

[0056] As Figures 9 to 14As shown, the bottom plate assembly for the switch device 100 according to the embodiment of the present disclosure generally includes a bottom plate 110 and a conductive temperature measurement assembly 115. The bottom plate assembly realizes multiple functions such as structural support and electrical connection.

[0057] Specifically, the bottom plate 110 includes a first body 103 and a plurality of first bases 113 , which are tightly combined by integral molding to form a solid and precise overall structure.

[0058] The first body 103, as the main part of the entire bottom plate 110, not only provides a support function, but also has limit posts 1101 arranged on the first body 103. These limit posts 1101 are arranged at positions adjacent to the first base 113. The limit posts 1101 provide precise positioning and fixing points for the conductive temperature measuring component 115.

[0059] Further, a plurality of first bases 113 are respectively arranged at both ends of the first body 103, respectively used to couple the circuit breaker 120 and the bottom shell 130. Each first base 113 includes a first fixing groove 1132 and a first receiving groove 1133. The first fixing groove 1132 is used to receive the first nut 114, providing support for subsequent electrical connection and fixation of the conductive temperature measuring component 115. The first receiving groove 1133 is used to receive the conductive temperature measuring component 115 to be described below.

[0060] Secondly, the one-piece molding method enhances the structural strength of the entire bottom plate 110, reduces the number of parts, and reduces production costs and failure rates. Secondly, the positioning column 1101 can ensure the precise positioning of the conductive temperature measuring component 115, thereby improving the convenience of installation and the reliability of the switch device 100.

[0061] Furthermore, the conductive temperature measuring component 115 integrates the functions of conduction, temperature measurement and fixing. The conductive temperature measuring component 115 includes an annular end 1151, a temperature measuring portion 1152 and a conductive portion 1154. Specifically, the annular end 1151 is arranged at the axial end of the first fixing groove 1132. Through the coupling of the bolt and the first nut 114, a reliable connection between the external conductive wire and the annular end 1151 can be achieved, which can not only ensure the stability of the electrical connection. For example, the conductive temperature measuring component 115 can be a Z-type terminal.

[0062] Furthermore, the temperature measuring portion 1152 is connected to the annular end portion 1151 at a non-zero angle. The temperature measuring portion 1152 has a built-in temperature sensor 102, which can monitor temperature changes in real time and provide data support for the intelligent operation of the circuit breaker 120. The temperature measuring portion 1152 is coupled in the first receiving groove 1133, thereby enhancing the stability and reliability of the conductive temperature measuring component 115.

[0063] Further, the conductive part 1154 is connected to one end of the temperature measuring part 1152 away from the annular end 1151, also maintaining a non-zero angle. The limiting hole 1155 on the conductive part 1154 can be precisely sleeved on the limiting post 1101 of the bottom plate 110, which not only ensures the stability of the conductive temperature measuring component 115, but also simplifies the assembly process.

[0064] As Figure 9 and Figure 10 shown, in some embodiments, the first body 103 includes a first part 111 and a second part 112. The first body 103 is divided into two splicable parts, which can improve the flexibility of the installation of the bottom plate 110. In other words, according to different application requirements or installation environments, these two parts can be selectively combined or replaced. For example, according to different models of circuit breakers 120 or specific installation requirements, different specifications or functions of the first part 111 or the second part 112 can be selected for combination, so as to achieve rapid customization of the product. In addition, the first body 103 can also adopt an integral structure, and the embodiments of the present disclosure do not make specific limitations on this.

[0065] In some embodiments, the bottom wall of the first receiving groove 1133 has a boss.

[0066] Specifically, the height of the boss in the vertical direction E is configured to exceed the height of the temperature sensor 102, so as to ensure that during the wiring process, the bolt will not directly contact the temperature sensor 102 in the receiving groove during installation and use, effectively avoiding damage to the temperature sensor 102 caused by extrusion or collision.

[0067] Further, the width of the first receiving groove 1133 is configured to be able to clamp the receiving part 1153, so that the conductive temperature measuring component 115 can be stably installed on the bottom plate 110. This clamping relationship simplifies the installation process. In other words, the receiving part 1153 can be inserted into the first receiving groove 1133 without complicated fixing steps, thereby improving the installation efficiency and facilitating subsequent maintenance and replacement work.

[0068] In some embodiments, the first nut 114 has an opening 1141 corresponding to the position of the temperature measuring part 1152. The opening 1141 provides a layout space for the conductive temperature measuring component 115, which can improve the assembly flexibility of the conductive temperature measuring component 115. The existence of the opening 1141 enables the conductive temperature measuring component 115 to be finely adjusted during the installation process to adapt to different installation environments and requirements.

[0069] As Figure 12 shown, in some embodiments, the temperature measuring part 1152 includes a receiving part 1153. The receiving part 1153 forms an integral body with other parts of the temperature measuring part 1152 through a bending process and is used to receive the temperature sensor 102.

[0070] Furthermore, the accommodation part 1153 is formed by bending and shaping, realizing the integration of the structure. This integrated structure can improve the strength and stability of the overall structure.

[0071] Secondly, the accommodation part 1153 provides an accurate installation space for the temperature sensor 102. The size and shape of the accommodation part 1153 can be set according to the temperature sensor 102 used, ensuring that the sensor can be stably installed and maintain the best thermal contact with the measured part. This not only improves the accuracy of temperature measurement but also enhances the stability and durability of the sensor during use.

[0072] As Figure 13 and Figure 14 shown, in some embodiments, a slideway 1131 structure is configured on the first base 113. The slideway 1131 is formed on both sides of the base along the insertion direction D of the circuit breaker 120, thereby improving the convenience, stability, and reliability of installation.

[0073] Furthermore, the slideway 1131 provides an accurate guidance and support for the first slide rail 1201 of the circuit breaker 120. Therefore, the slideway 1131 allows the circuit breaker 120 to smoothly and accurately slide into the predetermined position of the bottom plate 110, greatly simplifying the installation process. Compared with the traditional fixing method, this sliding installation not only reduces the installation time but also significantly reduces the risk of installation errors. The installer only needs to align the slide rail of the circuit breaker 120 with the slideway 1131 to accurately push the circuit breaker 120 into the correct position.

[0074] In some embodiments, the bottom case 130 is coupled to the slideway 1131 of the bottom plate assembly through the second slide rail 1301 in a manner similar to the installation of the circuit breaker 120, which will not be elaborated here.

[0075] The above has described the various implementations of the present disclosure. The above description is exemplary and not exhaustive, and is not limited to the disclosed implementations. Many modifications and changes are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described implementations. The selection of the terms used herein is intended to best explain the principles of the implementations, practical applications, or improvements to the technologies in the market, or to enable other ordinary technical personnel in the technical field to understand the various implementation manners disclosed herein.
