[0048] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0049] Reference is made below to Figures 1 - 15 Describe the busbar clamp assembly 100 according to an embodiment of the present application. The busbar clamp assembly 100 can be applied to an electrical cabinet 1000, and the connecting row 300 in the electrical cabinet 1000 can be clamped and fixed by the busbar clamp assembly 100. Among them, the connecting row 300 can be configured as a copper row.

[0050] The busbar clamp assembly 100 according to an embodiment of the present application includes a clamping assembly 1. The clamping assembly 1 includes a first clamping block 11 and a second clamping block 12, and a clamping groove 101 is formed between the first clamping block 11 and the second clamping block 12. The connecting row 300 can be clamped and fixed in the clamping groove 101, so that the connecting row 300 is clamped and arranged between the first clamping block 11 and the second clamping block 12, and the connecting row 300 is clamped and fixed by the clamping assembly 1.

[0051] As Figure 1 、 Figure 3 and Figure 5 shown, the clamping assembly 1 further includes a positioning block 13. The positioning block 13 is movably arranged on the first clamping block 11, and the positioning block 13 can approach or move away from the second clamping block 12. The positioning block 13 is used to press and position the connecting row 300 to fix the position of the connecting row 300 in the clamping groove 101.

[0052] It can be understood that during the process of fixing the connecting row 300 to the bus bar clamp assembly 100, the connecting row 300 is first arranged in the clamping groove 101, and the positioning block 13 is further driven to move towards the second clamping block 12 side, so as to press and position the connecting row 300 through the positioning block 13, thereby fastening the connecting row 300 to the clamping assembly 1. The installation method is simple and highly reliable, enabling the clamping assembly 1 to adapt to connecting rows 300 of various sizes and improving the versatility of the bus bar clamp assembly 100.

[0053] It should be noted that in the related art, the connecting row is fastened to the bus bar clamp through components such as bolts, resulting in difficult installation of the connecting row and ineffective control of the installation torque exerted by the bolts on the connecting row. That is to say, in the existing solution, the two clamping blocks are connected by fasteners to clamp the connecting row, and during disassembly and assembly, it is necessary to turn the fasteners, resulting in inconvenient operation during the disassembly and assembly process of the connecting row.

[0054] In the present application, a position-adjustable positioning block 13 is provided on the first clamping block 11. By adjusting the position of the positioning block 13, the connecting row 300 is fastened in the clamping groove 101, and the installation method is simple. Thus, through the pressing and matching of the positioning block 13 and the connecting row 300, the connecting row 300 is clamped and fixed in the clamping groove 101, reducing the disassembly and assembly difficulty of the connecting row 300 while ensuring the assembly reliability of the connecting row 300.

[0055] In some embodiments of the present application, the bus bar clamp assembly 100 further includes a detection component. The detection component is arranged on the clamping assembly 1, and the detection component is used to detect at least one of the installation torque, voltage, current, and temperature of the connecting row 300. Thus, the operating state of the bus bar clamp assembly 100 and the connecting row 300 can be monitored according to the parameters detected by the detection component, early warning of faults can be realized, preventive maintenance of the electrical cabinet 1000 equipment can be facilitated, and further the operation and maintenance cost can be reduced to achieve intelligent monitoring.

[0056] Specifically, by detecting the installation torque at the connecting row 300 through the bus bar clamp assembly 100, the clamping and fixing effect of the bus bar clamp assembly 100 on the connecting row 300 can be determined based on the installation torque parameter, avoiding problems such as loosening at the connecting row 300. At the same time, the installation torque parameter can also be used to assist in the assembly of the connecting row 300. When the installation torque of the connecting row 300 reaches the preset value, the operator can determine that the connecting row 300 is clamped and fixed.

[0057] When detecting the voltage of the connection row 300 through the detection component, if the voltage at the connection row 300 is not within the preset threshold range, it indicates that the connection row 300 needs to be inspected to eliminate potential safety hazards; when detecting the current of the connection row 300 through the detection component, if the current at the connection row 300 is not within the preset threshold range, it indicates that the connection row 300 needs to be inspected to eliminate potential safety hazards. When detecting the temperature of the connection row 300 through the detection component, if the temperature at the connection row 300 is not within the preset threshold range (e.g., the temperature of the connection row 300 is too high), it indicates that there are potential safety hazards at the connection row 300, such as poor contact between the connection rows 300, harmonic interference, etc., and it is necessary to check the mating part of the busbar clamp assembly 100 and the connection row 300.

[0058] Among them, when detecting the voltage and current at the connection row 300 through the detection component, the resistance value can be further obtained based on the voltage value and the current value, and whether there are potential safety hazards at the connection row 300 can be judged based on the resistance value. For example: due to reasons such as poor contact or corrosion at the connection row 300, the resistance between the connection rows 300 increases.

[0059] It should be noted that currently, in electrical equipment, the connection row 300 is clamped and fixed by the busbar clamp. In the related art, the function of the busbar clamp is single, only having the function of fixing the connection row 300, and it is unable to detect the operating state of the connection row 300. If a fault occurs at the connection row 300, it will cause the current to burn the equipment, and the fault location cannot be quickly identified.

[0060] In this application, a detection component is provided in the busbar clamp assembly 100. Through the detection component, at least one of the installation torque of the connection row 300 and the voltage, current, and temperature when the connection row 300 is operating (i.e., in the energized state) can be detected. Thus, the operating state of the busbar clamp assembly 100 and the connection row 300 can be monitored in real time based on the detection parameters, and then potential safety hazards existing at the busbar clamp assembly 100 and the connection row 300 can be promptly checked, improving the cooperation reliability of the busbar clamp assembly 100 and the connection row 300, and enhancing the safety of the busbar clamp and the connection row 300.

[0061] It should be noted that the busbar clamp assembly 100 in this application can be applied to the electrical cabinet 1000. Multiple groups of busbar clamp assemblies 100 can be provided in the electrical cabinet 1000 to clamp and fix the connection row 300 through the busbar clamp assembly 100. Each group of busbar clamp assemblies 100 can be used to detect the connection row 300. If the detection data of one group of busbar clamp assemblies 100 is abnormal, the position of the faulty busbar clamp assembly 100 can be judged, so as to facilitate the maintenance personnel to determine the source of the fault in a timely manner and improve the fault checking efficiency.

[0062] In some embodiments of the present application, the detection component further includes a current detection element 21. The current detection element 21 is disposed on the clamping component 1, and the current detection element 21 is used to detect the current value at the connection row 300, so that the operating state of the connection row 300 can be monitored based on the current value at the connection row 300. For example, if the current value exceeds a preset threshold, it indicates that there is a short - circuit problem at the connection row 300.

[0063] Among them, the current detection element 21 can be configured as a current detection sensor, such as detection components like coils.

[0064] Refer to Figure 1 、 Figure 3 、 Figure 5 and Figure 6 The current detection element 21 is embedded in the clamping component 1. For example, the current detection element 21 is arranged in the second clamping block 12 by an embedding method. Of course, the current detection element 21 can also be arranged in the first clamping block 11. Among them, the number of the current detection elements 21 is multiple, and the multiple current detection elements 21 can improve the accuracy of current detection at the connection row 300.

[0065] In some embodiments of the present application, the detection component further includes a voltage detection element 22. The voltage detection element 22 is disposed on the clamping component 1, and the voltage detection element 22 can be electrically connected to the connection row 300, and the voltage detection element 22 is used to detect the voltage value at the connection row 300, so that the operating state of the connection row 300 can be monitored based on the voltage value at the connection row 300.

[0066] Among them, the voltage detection element 22 can be configured as a voltage detection sensor.

[0067] Refer to Figure 5 and Figure 11 As shown in

[0068] Refer to Figure 5 and Figure 6 The voltage detection element 22 is arranged on the positioning block 13, and when the positioning block 13 is in positioning cooperation with the connection row 300, the voltage detection element 22 can abut against the connection row 300, so as to detect the voltage at the connection row 300 through the voltage detection element 22; Refer to Figure 11 The voltage detection element 22 is arranged on the second clamping block 12, and when the connection row 300 is fixed in the clamping groove 101, the voltage detection element 22 can be in abutting contact with the connection row 300, so as to detect the voltage at the connection row 300 through the voltage detection element 22.

[0069] Refer toFigure 11 It can be seen that when a plurality of clamping grooves 101 are formed in the busbar clamp assembly 100, a plurality of voltage detectors 22 are arranged in the busbar clamp assembly 100, and the plurality of voltage detectors 22 are respectively arranged in different clamping grooves 101 to detect the connection bars 300 in the plurality of clamping grooves 101 through the plurality of voltage detectors 22, so that a group of busbar clamp assemblies 100 can monitor while fixing multiple groups of connection bars 300.

[0070] In a further embodiment of the present application, the clamping assembly 1 further includes: a driving member 14 and a first elastic member 15. The driving member 14 is arranged on the first clamping block 11. The first elastic member 15 is respectively connected to the driving member 14 and the positioning block 13, and the driving member 14 is used to drive the first elastic member 15 to drive the positioning block 13 to move, so that the positioning block 13 approaches or moves away from the second clamping block 12 toward the second clamping block 12.

[0071] Refer to Figure 2 , the driving member 14 can be configured as a driving bolt. A threaded hole that is threadedly engaged with the driving bolt is provided on the first clamping block 11. By screwing the driving bolt into or out of the first clamping block 11, the first elastic member 15 is driven to drive the positioning block 13 to approach or move away from the second clamping block 12.

[0072] It can be understood that when the positioning block 13 is in pressing fit with the connection bar 300, as the driving bolt is further screwed in, the first elastic member 15 will be compressed by the driving member 14 and the positioning block 13. The positioning block 13 can be pressed against the connection bar 300 through the first elastic member 15 to ensure the pressing and fixing effect of the positioning block 13 on the connection bar 300. Among them, when the positioning block 13 is pressed against the connection bar 300, the position of the positioning block 13 is fixed. As the driving bolt is screwed in, the energy storage of the first elastic member 15 gradually increases, and the installation torque applied by the positioning block 13 to the connection bar 300 gradually increases to improve the fixing effect of the positioning block 13 on the connection bar 300.

[0073] In the present application, the driving member 14 drives the elastic member to drive the positioning block 13 to move, so that the installation torque applied by the positioning block 13 to the connection bar 300 can be gradually increased, which is convenient for controlling the installation torque. Among them, when it is detected by the detection assembly that the installation torque at the connection bar 300 reaches the preset requirement, the driving of the driving member 14 is stopped to keep the installation torque within the preset requirement range and complete the assembly.

[0074] Furthermore, during the disassembly process of the connection bar 300, the operator can reduce the installation torque applied by the positioning block 13 to the connection bar 300 by rotating the driving bolt. After the connection bar 300 is loosened, the connection bar 300 is then disassembled. Among them, after the connection bar 300 is loosened, the first clamping block 11 and the second clamping block 12 can be further separated to open the clamping groove 101, which is convenient for taking out the connection bar 300.

[0075] As Figure 5 and Figure 8 shown, in some embodiments of the present application, the detection component includes a temperature detection element 23, the temperature detection element 23 is arranged on the pressing surface 131 of the positioning block 13, and the temperature detection element 23 is used to detect the temperature value at the connection row 300.

[0076] Wherein, the positioning block 13 is used for press-fitting with the connection row 300. When the pressing surface 131 of the positioning block 13 abuts against the connection row 300, the temperature detection element 23 can detect the temperature at the connection row 300 to realize real-time monitoring of the temperature of the connection row 300.

[0077] It can be understood that the busbar clamp assembly 100 can communicate with the monitoring background. When the temperature at the connection row 300 exceeds the preset threshold, it indicates that the temperature at the connection row 300 is too high and it is necessary to go to the site (i.e., at the electrical cabinet 1000) for processing in time.

[0078] As Figure 5 and Figure 8 shown, in some embodiments of the present application, the detection component includes a pressure detection element 24, the pressure detection element 24 is arranged on the pressing surface 131 of the positioning block 13, and the pressure detection element 24 is used to detect the installation torque at the connection row 300.

[0079] Wherein, the pressure detection element 24 can be configured as a pressure sensor. When the positioning block 13 is press-fitted with the connection row 300, the pressure detection element 24 can detect the installation torque at the connection row 300 to realize real-time monitoring of the installation torque at the connection row 300.

[0080] It can be understood that the pressure detection element 24 can detect the installation torque when the busbar clamp assembly 100 is installed and fitted with the connection row 300 to assist the operator in assembling and control the installation torque at the connection row 300 within a suitable range to ensure the installation reliability at the connection row 300. At the same time, after the busbar clamp assembly 100 is installed and fitted with the connection row 300, the pressure detection element 24 can also perform real-time monitoring of the installation torque at the connection row 300 to prevent loosening at the connection row 300, which may cause potential safety hazards. For example: when it is monitored that the torque at the connection row 300 decreases, it indicates that there is a risk of loosening at the connection row 300, and it is necessary for the operator to go to the site to repair the equipment (such as: the electrical cabinet 1000) to prevent failures and timely eliminate the risks that may cause equipment failures and ensure the operation reliability of the equipment.

[0081] As Figure 5 and Figure 6As shown, in some embodiments of the present application, the detection component includes a voltage detector 22, which is disposed on the pressing surface 131 of the positioning block 13, and the voltage detector 22 is used to detect the voltage value at the connection row 300.

[0082] Among them, the voltage detector 22 can be configured as a voltage sensor. When the positioning block 13 is in pressing fit with the connection row 300, the voltage detector 22 can contact the connection row 300 to detect the voltage value at the connection row 300, thereby realizing real-time monitoring of the voltage at the connection row 300.

[0083] Combined with Figure 1 and Figure 10 , in some embodiments of the present application, the second clamping block 12 has a receiving groove 121 that opens toward the first clamping block 11, and a separating protrusion 122 is provided in the receiving groove 121. The separating protrusion 122 protrudes from the bottom wall of the receiving groove 121 toward the first clamping block 11 and is disposed opposite to the positioning block 13. By cooperating the separating protrusion 122 with the positioning block 13, a plurality of clamping grooves 101 can be separated and formed between the first clamping block 11 and the second clamping block 12.

[0084] Thus, by providing the separating protrusion 122 at the clamping component 1 to separate the space between the first clamping block 11 and the second clamping block 12, a plurality of clamping grooves 101 are formed, so that multiple groups of connection rows 300 can be clamped by the busbar clamp assembly 100.

[0085] Combined with Figure 14 and Figure 15 , it can be understood that the busbar clamp assembly 100 in the present application can be applied to the electrical cabinet 1000. There can be various-phase connection rows 300 in the electrical cabinet 1000. The connection rows 300 of the same phase can be arranged in the same clamping groove 101 and clamped and fixed by the clamping component 1 to electrically connect the two connection rows 300 of the same phase.

[0086] Referring to Figure 15 , the electrical cabinet 1000 may include a plurality of cabinet bodies 200 (such as: incoming line cabinet, feeder cabinet, etc.). The connection rows 300 between two adjacent cabinet bodies 200 can be fixed in the same clamping groove 101 by a set of busbar clamp assembly 100. When the electrical cabinet 1000 has connection rows 300 of three phases, the connection rows 300 of the same phase in two adjacent cabinet bodies 200 are fixed in the same clamping groove 101.

[0087] Thus, by providing a separating structure (i.e., the separating protrusion 122) in the clamping component 1, a plurality of clamping grooves 101 can be formed in the clamping component 1, so that multiple groups of connection rows 300 can be respectively clamped and fixed by a set of busbar clamp assembly 100, improving the versatility of the busbar clamp assembly 100.

[0088] As Figure 1 and Figure 3 shown, in a further embodiment of the present application, there are multiple separating protrusions 122, and the multiple separating protrusions 122 are arranged at intervals in the receiving groove 121, and there are multiple positioning blocks 13, and the multiple positioning blocks 13 are respectively arranged in one-to-one correspondence with the multiple separating protrusions 122, so as to form multiple independent clamping grooves 101 at the clamping assembly 1 through multiple groups of correspondingly arranged positioning blocks 13 and separating protrusions 122, so that we can clamp and fix multiple groups of connecting rows 300 through the busbar clamp assembly 100.

[0089] Further in combination with Figure 14 , two positioning protrusions are provided at the second clamping block 12 to separate the receiving groove 121 formed by the second clamping block 12 through the positioning protrusions, forming three clamping grooves 101. Among them, two connecting rows 300 with the same phase can be placed in each clamping groove 101, and the two connecting rows 300 are fixed in the clamping groove 101 under the pressing action of the positioning block 13. It can be understood that the second clamping block 12 can play a role in pre-positioning the connecting row 300, and through the pressing cooperation between the positioning block 13 and the connecting row 300, the two connecting rows 300 can be tightly fixed in the clamping groove 101 to realize the assembly of the connecting row 300 and the busbar clamp assembly 100.

[0090] In the description of the present application, the meaning of "multiple" is two or more, not limited to two.

[0091] As Figure 14 shown, in some embodiments of the present application, the positioning block 13 is provided with a pressing surface 131 facing one side of the clamping groove 101, and the pressing surface 131 is used for pressing cooperation with the connecting row 300 to press and fix the connecting row 300 in the clamping groove 101.

[0092] Referring to Figure 14 , in the moving direction of the positioning block 13, at least part of the pressing surface 131 is disposed opposite to the bottom wall of the second clamping block 12 to ensure the pressing and positioning effect of the positioning block 13 on the connecting row 300.

[0093] It can be understood that during the installation process of the connecting row 300, the connecting row 300 is first arranged at the clamping groove 101 formed by the second clamping block 12, and is further clamped by the positioning block 13 to fix the connecting row 300 in the clamping groove 101. Referring to Figure 14 , the positioning block 13 moves relative to the second clamping block 12 in the vertical direction in the figure in the clamping assembly 1. As the positioning block 13 approaches the second clamping block 12, the pressing surface 131 can abut against the connecting row 300 and apply a pressing force to the connecting row 300 to press and fix the two connecting rows 300 in the same clamping groove 101.

[0094] Referring to Figure 14, in some embodiments, the pressing surface 131 is inclined with respect to the moving direction of the positioning block 13. When the connecting rows 300 in the second clamping block 12 are arranged in the left - right direction, a pressing force with a left - right direction component can be applied to the connecting rows 300 through the pressing surface 131, so that the two connecting rows 300 are fully attached to each other, thereby ensuring the electrical connection effect between the two connecting rows 300.

[0095] Referring to Figure 5 and Figure 6 , in some embodiments, the pressing surface 131 is a plane, and the pressing surface 131 is arranged parallel to the bottom wall of the groove of the second clamping block 12 (the side wall surface opposite to the positioning block 13). At the same time, only one clamping groove 101 is formed in the bus bar clamping assembly 100. In the clamping groove 101, the two connecting rows 300 are arranged in the left - right direction in the figure, and the positioning block 13 can move relative to the second clamping block 12 in the left - right direction in the figure. When the positioning block 13 is in pressing fit with the connecting row 300, the two connecting rows 300 can be tightly fixed at the clamping groove 101 formed by the second clamping block 12.

[0096] It can be understood from this that the arrangement of the pressing surface 131 is related to the arrangement positions of the positioning block 13 and the second clamping block 12 and the arrangement manner of the connecting rows 300 in the second clamping block 12.

[0097] As Figure 1 shown, in a further embodiment of the present application, the positioning block 13 is provided with two pressing surfaces 131 arranged back to back. The two pressing surfaces 131 are respectively oriented towards two adjacent connecting rows 300 arranged in the clamping groove 101, and the distance between the two pressing surfaces 131 gradually decreases from the side close to the first clamping block 11 to the side of the separating protrusion 122.

[0098] Among them, the two pressing surfaces 131 are respectively used for pressing fit with the connecting rows 300 in the two clamping grooves 101 on both sides of it. Thus, a pressing force can be applied to two groups of connecting rows 300 respectively through one positioning block 13 to ensure the pressing and positioning effect on the connecting rows 300.

[0099] Referring to Figure 14 , three clamping grooves 101 are formed in the bus bar clamping assembly 100, and two positioning blocks 13 are arranged on the first clamping block 11. The two positioning blocks 13 are respectively arranged corresponding to the two separating protrusions 122, and each positioning block 13 is formed with two pressing surfaces 131. The two pressing surfaces 131 are respectively in pressing fit with the connecting rows 300 in the two clamping grooves 101 on both sides of it. Among them, the two connecting rows 300 in the middle clamping groove 101 are respectively in pressing fit with the two positioning blocks 13, and the two positioning blocks 13 can respectively press the two connecting rows 300 to be close to each other to ensure the contact effect between the two connecting rows 300.

[0100] AsFigure 1 As shown, in some embodiments of the present application, the first clamping block 11 is provided with a first connecting arm 111 extending towards the second clamping block 12, and the second clamping block 12 is provided with a second connecting arm 123 extending towards the first clamping block 11, and the first connecting arm 111 is connected to the second connecting arm 123.

[0101] Thus, through the connection and cooperation of the first connecting arm 111 and the second connecting arm 123, the first clamping block 11 and the second clamping block 12 can be fixed, and an installation space for arranging the connection row 300 is defined between the first clamping block 11 and the second clamping block 12.

[0102] As Figure 14 shown, in a further embodiment of the present application, the first connecting arm 111 and the second connecting arm 123 are configured into two groups, the connection row 300 is located between the two groups of the first connecting arm 111 and the second connecting arm 123, and at least one group of the first connecting arm 111 and the second connecting arm 123 are detachably connected. Thus, it is convenient to install and cooperate the first clamping block 11 and the second clamping block 12, and it is also convenient to install the connection row 300.

[0103] Referring to Figure 1 、 Figure 5 and Figure 14 , both groups of the first connecting arm 111 and the second connecting arm 123 are configured to be detachably connected. During the installation process of the connection row 300, the connection row 300 can be first arranged in the second clamping block 12, and then the first clamping block 11 is installed on the second clamping block 12. By connecting and cooperating the two groups of the first connecting arm 111 and the second connecting arm 123, the first clamping block 11 and the second clamping block 12 are installed and fixed.

[0104] As Figure 6 shown, in some embodiments of the present application, the first connecting arm 111 and the second connecting arm 123 are configured into two groups, and one group of the first connecting arm 111 and the second connecting arm 123 are detachably connected, and the other group of the first connecting arm 111 and the second connecting arm 123 are pivotally connected. Thus, the first clamping block 11 and the second clamping block 12 can remain connected.

[0105] Specifically, one group of the first connecting arm 111 and the second connecting arm 123 are selectively connected by a pin 16, and the other group of the first connecting arm 111 and the second connecting arm 123 are flipably connected by a hinge structure 4. During the installation process of the connection row 300, the connection row 300 is first arranged in the second clamping block 12, and then the first clamping block 11 is buckled with the second clamping block 12 by flipping, and further the first clamping block 11 and the second clamping block 12 are installed and fixed. Among them, the installation method of the first clamping block 11 and the second clamping block 12 is simple and highly reliable.

[0106] As Figure 1As shown, in some embodiments of the present application, the first connecting arm 111 is formed with a mounting groove 112 that opens towards one side of the second clamping block 12. The second connecting arm 123 is provided with a plugging protrusion 124, and the plugging protrusion 124 is in plugging fit with the mounting groove 112, so as to position the first clamping block 11 and the second clamping block 12 by plugging, facilitating the fixing of the first clamping block 11 and the second clamping block 12.

[0107] Referring to Figure 1 , the plugging protrusion 124 protrudes from the upper end of the second connecting arm 123 (i.e., the end close to the first clamping block 11) towards the first clamping block 11, and the first clamping block 11 can be in plugging fit with the second clamping block 12 through an installation method from top to bottom. The installation method is simple and has high reliability.

[0108] As Figure 7 shown, in a further embodiment of the present application, the first connecting arm 111 is further provided with a slot 113. The slot 113 penetrates through the side wall of the first connecting arm 111 and is communicated with the mounting groove 112, and the plugging protrusion 124 is provided with a positioning groove 125.

[0109] Wherein, the clamping assembly 1 further includes a pin 16. The pin 16 can penetrate through the slot 113 and be in plugging positioning with the positioning groove 125. It can be understood that by plugging the plugging protrusion 124 with the mounting groove 112, the first clamping block 11 and the second clamping block 12 can be pre-positioned. And when the positioning groove 125 of the plugging protrusion 124 is opposite to the slot 113, the first clamping block 11 is locked with the plugging protrusion 124 through the pin 16 to fix the first clamping block 11 and the second clamping block 12, improving the installation reliability of the first clamping block 11 and the second clamping block 12.

[0110] It can be understood that the first clamping block 11 and the second clamping block 12 are fixed by the pin 16. The installation method is simple and has high reliability, which can reduce the assembly difficulty of the first clamping block 11 and the second clamping block 12 while ensuring the assembly accuracy of the first clamping block 11 and the second clamping block 12.

[0111] As Figure 1 shown, in some embodiments of the present application, the clamping assembly 1 further includes a second elastic member 17. The second elastic member 17 is disposed in the mounting groove 112, and the second elastic member 17 elastically supports between the end of the plugging protrusion 124 and the bottom wall of the mounting groove 112, and the second elastic member 17 stores energy when the first clamping block 11 and the second clamping block 12 are fixed, so as to ensure the installation reliability of the first clamping block 11 and the second clamping block 12.

[0112] It should be noted that, in the process of assembling the first clamping block 11 and the second clamping block 12, the plugging protrusion 124 is first plugged into the mounting groove 112, and the end of the plugging protrusion 124 is pressed against the second elastic member 17. Under the action of the second elastic member 17, the mounting groove 112 formed on the plugging protrusion 124 is misaligned with the slot 113 in the first connecting arm 111, and the first clamping block 11 needs to be further pressed and driven toward the second clamping block 12 to make the positioning groove 125 face the slot 113. At this time, the latch 16 is inserted into the slot 113 and plugged into the positioning groove 125, and the first clamping block 11 and the second clamping block 12 are locked in the plugging direction of the plugging protrusion 124, so as to achieve the fixation of the first clamping block 11 and the second clamping block 12.

[0113] Reference Figure 1 When the first clamping block 11 and the second clamping block 12 are fixed by the latch 16, the second elastic member 17 is clamped by the bottom wall of the mounting groove 112 and the end of the plug-in protrusion 124, and the second elastic member 17 is in an energy storage state, that is, the second elastic member 17 has an operating tendency to drive the plug-in protrusion 124 to escape from the mounting groove 112. When it is necessary to separate the first clamping block 11 from the second clamping block 12, the latch 16 can be pulled out, and under the drive of the second elastic member 17, the plug-in protrusion 124 can be easily escaped from the mounting groove 112, so as to separate the first clamping block 11 from the second clamping block 12.

[0114] It can be understood that since the first clamp block 11 and the second clamp block 12 are locked by the latch pin 16, and the second elastic member 17 is in an energy storage state, a shear force can be applied to the latch pin 16 at the positioning groove 125 of the plug-in protrusion 124, thereby increasing the damping between the latch pin 16 and the positioning groove 125 to prevent the latch pin 16 from escaping from the positioning groove 125, thereby further improving the connection reliability between the first clamp block 11 and the second clamp block 12.

[0115] like Figure 2 As shown, in some embodiments of the present application, at least one of the first clamping block 11 and the second clamping block 12 is provided with a display device 18, which is electrically connected to the detection assembly and is used to display at least one of the installation torque value, voltage value, current value and temperature value. The display device 18 is configured as a display screen.

[0116] It should be noted that when the detection component includes a voltage detection component 22 (voltage sensor), a current detection component 21, a temperature detection component 23 (such as a temperature sensor), and a pressure detection component 24 (such as a pressure sensor), multiple parameters can be simultaneously displayed on the display device 18, facilitating the operator to judge the faults at the busbar clamp assembly 100 and the connection bar 300 based on the parameter information and improving the troubleshooting efficiency. Among them, the parameters displayed by the display device 18 are not limited to the installation torque value, voltage value, current value, and temperature value, but can also include parameters such as resistance (such as phase-to-phase resistance, ground resistance, etc.) obtained based on the voltage value and current value.

[0117] It can be understood that when the first clamping block 11 is arranged above the second clamping block 12, the top of the first clamping block 11 is the side convenient for the operator to observe, and the display device 18 can be arranged on the top of the first clamping block 11 to facilitate the operator to observe the parameter information displayed on the display screen.

[0118] Such as Figure 2 As shown, in some embodiments of the present application, the busbar clamp assembly 100 further includes a battery 3. The battery 3 is arranged on the clamping assembly 1 and is used to supply power to the display device 18, so that when the connection bar 300 is not connected to the power supply, the installation torque and other parameter information can be displayed through the display device 18 to assist the operator in assembling the busbar clamp assembly 100 and the connection bar 300.

[0119] Among them, the battery 3 can be arranged at a position close to the display device 18 to facilitate supplying power from the battery 3 to the display device 18 and the pressure detection component 24.

[0120] It should be noted that when the busbar clamp assembly 100 is installed and fixed to the connection bar 300, the connection bar 300 is in an energized state, and the display device 18 can be electrically connected to the connection bar 300 through the detection component to realize the display function of the display device 18.

[0121] In some embodiments of the present application, at least one of the first clamping block 11 and the second clamping block 12 is provided with an electrical connection portion 19. The electrical connection portion 19 is used to be electrically connected to the terminal (such as communication connection), so as to feedback the parameter information detected by the detection component to the terminal, facilitating the monitoring personnel at the terminal to timely understand the working state of the electrical cabinet 1000, eliminate potential safety hazards in a timely manner, and improve safety. Among them, the terminal device can be configured as devices such as mobile phones and computers.

[0122] Refer to Figure 9 As shown, the electrical connection portion 19 is arranged on the first clamping block 11, and the electrical connection portion 19 is configured as a wiring port, such as a 485 communication interface, etc. Among them, the interface type of the electrical connection portion 19 needs to conform to the electrical standard of the interface, and no specific limitation is made here.

[0123] Such as Figure 11and Figure 13 As shown, in some embodiments of the present application, the second clamping block 12 is further provided with a fixing portion 126, and the fixing portion 126 is used to fix the second clamping block 12 at the installation position. For example: the second clamping block 12 is fixed on the cabinet body 200 through the fixing portion 126 to ensure the fixing effect of the busbar clamp assembly 100 on the connecting row 300.

[0124] Further, the fixing portion 126 can be configured as a mounting bolt, and the mounting bolt is arranged at the bottom of the second clamping block 12. Referring to Figure 11 , the mounting bolt is arranged at the bottom wall of the clamping groove 101 formed by the second clamping block 12, and the mounting bolt is arranged through the second clamping block 12 in the thickness direction. By screwing in the mounting bolt, the second clamping block 12 can be fixed at the cabinet body 200; referring to Figure 13 , the mounting bolt is arranged at the side wall of the second clamping block 12, and the mounting bolt is arranged through the second clamping block 12 in the width direction. By screwing in the mounting bolt, the second clamping block 12 can be fixed at the cabinet body 200.

[0125] Wherein, Figure 11 and Figure 13 the setting positions of the mounting bolts in

[0126] are different, and the screwing-in methods of the mounting bolts are also different. Thus, the setting position of the mounting bolt in the second clamping block 12 can be designed according to the installation and mating position between the second clamping block 12 and the cabinet body 200. Figures 1 - 14 Combined with

[0127] Describe the assembly process of the busbar clamp assembly 100 according to the embodiments of the present application:

[0128] Fix the second clamping block 12 at the cabinet body 200, arrange the connecting row 300 in the receiving groove 121 formed by the second clamping block 12, and then fasten the first clamping block 11 on the second clamping block 12. At this time, the connecting row 300 is arranged in the clamping groove 101. By pressing the first clamping block 11, the slot 113 is aligned with the positioning slot 125 (at this time, the second elastic member 17 stores energy), and the pin 16 is inserted into the slot 113 and the positioning slot 125 to realize the fixation of the first clamping block 11 and the second clamping block 12.

[0128] Subsequently, the operator further operates the driving member 14 to drive the positioning block 13 to move toward the side close to the second clamping block 12, and the connecting row 300 is pressed and positioned through the positioning block 13. At this time, the positioning block and the second clamping block can jointly clamp and fix the connecting row. When the positioning block 13 presses against the connecting row 300, the pressure detection member 24 can detect the installation torque at the connecting row 300, and the installation torque value can be displayed on the display device 18, so that the operator can timely understand the real-time installation torque of the connecting row 300, and thus the installation torque of the connecting row 300 can be controlled within the preset parameter range to ensure the installation reliability of the connecting row 300.

[0129] In some embodiments, the pressure detection member 24 is configured as a piezoresistor. As the installation torque increases, the resistance of the piezoresistor gradually decreases. When the resistance value of the piezoresistor decreases to a preset value, the battery 3 can supply power to light up the display device 18 to display data (such as installation torque, etc.) to assist the operator in controlling the installation torque of the connection row 300 within a preset threshold range.

[0130] According to the embodiment of the present application, the busbar clamp assembly 100 has the functions of real-time monitoring of the fastening condition of the connection row 300 and the current operating state of the connection row 300, as follows:

[0131] (1) It can monitor the fastening condition of the connection row 300 in real time

[0132] A pressure detection member 24 is provided in the busbar clamp assembly 100 of the present application. After the busbar clamp assembly 100 and the connection row 300 are assembled, the pressure detection member 24 can detect the installation torque at the connection row 300 in real time.

[0133] Among them, the installation torque at the connection row 300 can be obtained at the terminal and is suitable for alarming after the installation torque value exceeds the preset threshold, so that the operator can go to the site in time to adjust the installation torque to ensure the connection reliability at the connection row 300.

[0134] (2) It can monitor the temperature of the connection row 300 in real time

[0135] A temperature detection member 23 is provided in the busbar clamp assembly 100 of the present application. After the busbar clamp assembly 100 and the connection row 300 are assembled, the temperature detection member 23 can detect the temperature at the connection row 300 in real time.

[0136] Among them, the temperature at the connection row 300 can be obtained at the terminal and is suitable for alarming after the temperature value is higher than the preset threshold, so that the operator can go to the site in time to troubleshoot, such as dealing with the problem of the connection row 300 heating up caused by various reasons such as poor contact or harmonic interference.

[0137] (3) It can monitor the resistance between the in-phase connection rows 300 in real time

[0138] A voltage detection member 22 and a current detection member 21 are provided in the busbar clamp assembly 100 of the present application. The voltage at the connection row 300 can be detected through the voltage detection member 22, and the current detection assembly can detect the current at the connection row 300. Based on the voltage and current, the resistance at the connection row 300 can be obtained.

[0139] Among them, the terminal can obtain the resistance at each set of connection bars 300 based on the current value and voltage value, and is adapted to alarm after the resistance exceeds a preset threshold, so that the operator can go to the site to troubleshoot, such as: dealing with problems such as increased phase-to-phase resistance of the connection bars 300 caused by various reasons such as poor contact or corrosion of the connection bars 300.

[0140] (4) The phase-to-phase resistance between connection bars 300 of different phases can be monitored in real time

[0141] It should be noted that this monitoring function is applicable to the busbar clamp assembly 100 that can simultaneously fix multiple sets of connection bars 300 of different phases (such as Figure 1 and Figure 3 shown in).

[0142] Combined with Figure 1 、 Figure 11 and Figure 15 it can be known that three clamping grooves 101 are formed in the busbar clamp assembly 100, and each clamping groove 101 can respectively arrange connection bars 300 of different phases, and voltage detection components 22 and current detection components 21 corresponding to the connection bars 300 in multiple clamping grooves 101 are provided in the clamping assembly 1.

[0143] Referring to Figure 11 , a plurality of voltage detection components 22 are provided on the bottom wall of the second clamping block 12, and the plurality of voltage detection components 22 are respectively arranged in the plurality of clamping grooves 101 to respectively detect the voltage of the connection bars 300 of different phases through the plurality of voltage detection components 22; referring to Figure 1 , a plurality of current detection components 21 are also provided in the second clamping block 12, the current detection components 21 are embedded in the second clamping block 12, and are used to detect the current at the connection bars 300. Based on the voltage values of the two sets of connection bars 300 and the vector value of the current, the phase-to-phase resistance between the two sets of connection bars 300 with different phases can be obtained.

[0144] (5) The insulation resistance of the busbar clamp assembly 100 to the ground can be monitored in real time

[0145] In the busbar clamp assembly 100 of the present application, a voltage detection component 22 and a current detection component 21 are provided. Referring to Figure 1 , the current detection component 21 is arranged in the second clamping block 12, and the current detection component 21 is located below the connection bars 300, that is, between the connection bars 300 and the ground. Based on the detection results of the voltage detection component 22 and the current detection component 21, the insulation resistance of the busbar clamp assembly 100 to the ground can be obtained to monitor the insulation resistance to the ground in real time.

[0146] It should be noted that based on the above different monitoring functions, corresponding alarm control strategies can be designed at the terminal.

[0147] In some embodiments, the pressure detection member 24 is configured as a piezoresistor.

[0148] In the fastening mode of monitoring the connection bar 300, if the monitored installation torque is less than the first preset pressure value (e.g., 100 N), the terminal can issue a corresponding alarm (e.g., a level-three alarm) to prompt that the installation torque of the connection bar 300 at the corresponding busbar clamp assembly 100 is small and the operator needs to go to the site in time for handling; if the monitored installation torque is less than the second preset pressure value (e.g., 90 N), the terminal can issue an alarm (e.g., a level-two alarm) to prompt that the installation torque of the connection bar 300 at the corresponding busbar clamp assembly 100 is small and the operator needs to go to the site in time for handling; if the monitored installation torque is less than the third preset pressure value (e.g., 80 N), the terminal can issue an alarm (e.g., a level-one alarm) to prompt that the installation torque of the connection bar 300 at the corresponding busbar clamp assembly 100 is small, the circuit breaker in the electrical cabinet 1000 (e.g., the incoming line cabinet) needs to be disconnected and power cut for handling, and the operator needs to go to the site in time for handling.

[0149] It should be noted that the preset pressure values (the first preset pressure value, the second preset pressure value, the third preset pressure value) and the alarm levels corresponding to the preset pressure values can be designed according to the installation requirements of the connection bar 300, and no specific limitation is made here.

[0150] In some embodiments, the temperature detection member 23 can be configured as a thermistor.

[0151] In the temperature mode of monitoring the connection bar 300, if the monitored temperature value reaches the first preset temperature (e.g., 60 °C), the terminal can issue an alarm to prompt that the temperature of the connection bar 300 at the corresponding busbar clamp assembly 100 is high and the operator needs to go to the site in time for handling; if the monitored temperature reaches the second preset temperature (e.g., 80 °C), the terminal can issue an alarm to prompt that the temperature at the corresponding busbar clamp assembly 100 is high and the operator needs to go to the site in time for handling; if the monitored temperature reaches the third preset temperature (e.g., 100 °C) to prompt that the temperature of the connection bar 300 at the corresponding busbar clamp assembly 100 is high, the terminal can issue an alarm, the circuit breaker in the electrical cabinet 1000 (e.g., the incoming line cabinet) needs to be disconnected and power cut for handling, and the operator needs to go to the site in time for handling.

[0152] It should be noted that the preset temperatures (the first preset temperature, the second preset temperature, the third preset temperature) and the alarm levels corresponding to the preset temperatures can be designed according to the operating requirements of the connection bar 300, and no specific limitation is made here.

[0153] In the mode of monitoring the resistance between the in-phase connection bars 300, if the resistance value between the in-phase connection bars 300 is greater than 1 Ω, the terminal can issue an alarm (e.g., a level-three alarm) to indicate that the resistance of the connection bar 300 at the corresponding busbar clamp assembly 100 is large, and the operator needs to go to the site in time for handling; if the resistance value between the in-phase connection bars 300 is greater than 5 Ω, the terminal can issue an alarm (e.g., a level-two alarm) to indicate that the resistance of the connection bar 300 at the corresponding busbar clamp assembly 100 is large, and the operator needs to go to the site in time for handling; if the resistance value between the in-phase connection bars 300 is greater than 10 Ω, the terminal can issue an alarm (e.g., a level-one alarm) to indicate that the resistance of the connection bar 300 at the corresponding busbar clamp assembly 100 is large, and the circuit breaker in the electrical cabinet 1000 (e.g., the incoming line cabinet) needs to be disconnected and power cut for handling, and the operator needs to go to the site in time for handling.
