Detailed Implementation

[0021] Hereinafter, exemplary embodiments according to this application will be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.

[0022] Figure 1 A schematic diagram of the internal structure of a microgrid cable detection and quick-connect cabinet provided as an exemplary embodiment of this application, viewed from a first perspective. Figure 2 This is a schematic diagram of the internal structure of a microgrid cable detection and quick-connect cabinet provided as an exemplary embodiment of this application, viewed from a second perspective. Figure 1 and Figure 2 As shown, the microgrid cable detection and quick-connect cabinet 100 provided in this application embodiment may include a cabinet 110, multiple sets of detection terminals 120 and multiple sets of cables 130. The multiple sets of detection terminals 120 are disposed inside the cabinet 110, and a portion of each set of cables 130 is disposed inside the cabinet 110. The multiple sets of cables 130 are electrically connected to the multiple sets of detection terminals 120 respectively.

[0023] In one embodiment, the multiple sets of cables 130 may include different types of cables. For example, the multiple sets of cables 130 may include control cables, signal cables, power cables, etc.

[0024] In one embodiment, each cable group 130 includes multiple cores, and each detection terminal group 120 includes multiple detection terminals 120, wherein the multiple cores can be electrically connected to the multiple detection terminals 120 respectively.

[0025] In one embodiment, a portion of each set of cables 130 is located inside the cabinet 110, and the portion of each set of cables 130 located outside the cabinet 110 can be used to connect different functional cabinets, such as remote communication cabinets, battery cabinets, UPS charging feeder cabinets, station power supply cabinets, and intelligent auxiliary cabinets.

[0026] It should be noted that a portion of each group of cables 130 and multiple groups of detection terminals 120 are located in the same cabinet 110. On the one hand, this can shorten the distance between the cables 130 and the detection terminals 120, making wiring easier; on the other hand, it can detect the connectivity status of different types of cables 130 within the same cabinet 110 (the detection process is described later), effectively improving detection efficiency.

[0027] like Figure 1 and Figure 2 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include multiple sets of resistance sensors 140 and multiple sets of voltage sensors 150. The multiple sets of resistance sensors 140 and multiple sets of voltage sensors 150 are all located inside the cabinet 110. The multiple sets of resistance sensors 140 are electrically connected to multiple sets of detection terminals 120 respectively, and the multiple sets of voltage sensors 150 are electrically connected to multiple sets of detection terminals 120 respectively.

[0028] In practical applications, the resistance sensor 140 can measure the contact resistance between the corresponding cable 130 and the detection terminal 120, and the voltage sensor 150 can measure the actual voltage between the cable 130 and the detection terminal 120.

[0029] like Figure 1 and Figure 2 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include a controller 160, which is communicatively connected to multiple sets of detection terminals 120, multiple sets of resistance sensors 140 and multiple sets of voltage sensors 150.

[0030] In practical applications, the controller 160 can determine the continuity status of the cable 130 based on the data detected by the resistance sensor 140 and the voltage sensor 150. Specifically, when the contact resistance detected by the resistance sensor 140 is within a preset resistance range, and the actual voltage detected by the voltage sensor 150 is within a preset voltage range, the controller 160 can output a first signal indicating that the continuity status of the cable 130 is normal; when the contact resistance detected by the resistance sensor 140 is outside the preset resistance range, and / or the actual voltage detected by the voltage sensor 150 is outside the preset voltage range, the controller 160 can output a second signal indicating that the continuity status of the cable 130 is abnormal.

[0031] It should be noted that the contact resistance detected by the resistance sensor 140 can determine whether there are problems such as looseness or oxidation causing poor contact between the cable 130 and the detection terminal 120. The actual voltage detected by the voltage sensor 150 can determine whether there are problems such as broken wires or short circuits in the cable 130. In other words, by using contact resistance and actual voltage to determine the continuity of the cable 130, a comprehensive assessment of the continuity of the cable 130 can be made, ensuring that the test results are accurate and reliable.

[0032] In one embodiment, both the resistance sensor 140 and the voltage sensor 150 are equipped with signal isolation modules in their sampling circuits. The signal isolation modules can reduce electromagnetic interference and signal crosstalk between different types of cables 130, improve the electromagnetic compatibility of the system, and reduce the risk of misjudgment or equipment damage caused by electrical interference.

[0033] The microgrid cable testing and quick-connect cabinet 100 provided in this application embodiment, on the one hand, by arranging multiple sets of cables 130 and multiple sets of testing terminals 120 in the same cabinet 110, and using resistance sensors 140 and voltage sensors 150 to test the connectivity of different types of cables 130 within the same cabinet 110, eliminates the need for personnel to use multimeters or other tools to test each set individually, effectively shortening testing time, improving testing efficiency, and reducing the workload of personnel; on the other hand, it uses the contact resistance detected by the resistance sensor 140 to determine whether there are problems such as looseness or oxidation between the cable 130 and the testing terminal 120, and uses the actual voltage detected by the voltage sensor 150 to determine whether there are problems such as broken wires or short circuits in the cable 130, so that the connectivity of the cable 130 can be comprehensively evaluated, ensuring that the test results are true and reliable, and effectively improving the reliability of the test results.

[0034] like Figure 1 and Figure 2 As shown, multiple sets of detection terminals 120 are arranged along the height direction of the cabinet 110 (reference). Figure 1 The cables are spaced apart along the Z-axis, which improves the problem of easy interference between multiple sets of cables 130 when multiple sets of cables 130 are connected to multiple sets of detection terminals 120 respectively, and facilitates simultaneous detection of the connection status of multiple sets of cables 130.

[0035] In one embodiment, the distance between any two adjacent sets of detection terminals 120 along the height direction of the cabinet 110 may be equal or unequal.

[0036] like Figure 1 and Figure 2 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include multiple guide rails 170, which are arranged along the height of the cabinet 110 (see reference). Figure 1 The detection terminals 120 are spaced apart along the Z-axis direction of the guide rail 170, and the same group of detection terminals 120 are snapped onto the same guide rail 170. Multiple detection terminals 120 in the same group are arranged along the length of the same guide rail 170 (see reference). Figure 1 (distributed at intervals along the X-axis).

[0037] It should be noted that multiple detection terminals 120 are snapped into the guide rail 170, which facilitates the installation and removal of the detection terminals 120, achieving the beneficial effect of quick disassembly and quick assembly.

[0038] It should be noted that the multiple detection terminals 120 in the same group are distributed at intervals along the length of the same guide rail 170. In this way, after the multiple cores of the cable 130 are connected to the multiple detection terminals 120, the problem of easy interference between the multiple cores of the cable 130 can be effectively improved.

[0039] In one embodiment, the guide rail 170 can be a dovetail groove structure, and the detection terminal 120 is provided with a slot that engages with the guide rail 170. Furthermore, the side wall of the slot is inclined relative to the bottom wall. After the side wall of the slot engages with the guide rail 170, it can prevent the detection terminal 120 from moving along the length direction of the guide rail 170, thereby improving the engagement stability of the detection terminal 120.

[0040] like Figure 1 As shown, a lighting device 290 can also be installed inside the cabinet 110. The lighting device 290 can increase the brightness inside the cabinet 110, making it easier for staff to connect the cable 130 and the detection terminal 120.

[0041] like Figure 1 As shown, a protective switch 310 can also be installed inside the cabinet 110. When the cable 130 experiences a short circuit or leakage, the protective switch 310 can quickly cut off the power supply to prevent damage to other equipment and prevent electrical fires.

[0042] like Figure 1 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include a grounding busbar 270, which is located inside the cabinet 110 and is electrically connected to multiple sets of detection terminals 120. It should be understood that the grounding busbar 270 can conduct current to the ground, ensuring the safety of the cabinet 110 and related internal equipment.

[0043] like Figure 1 As shown, the cabinet 110 is equipped with a cable channel 280, and multiple sets of cables 130 are run through the cable channel 280. The cable channel 280 can be used to store multiple sets of cables 130, effectively avoiding mechanical damage to the multiple sets of cables 130.

[0044] like Figure 2 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include a power supply module 320, which is electrically connected to the controller 160, multiple sets of resistance sensors 140 and multiple sets of voltage sensors 150.

[0045] It should be understood that the power supply module 320 can provide power to the controller 160, multiple sets of resistance sensors 140 and multiple sets of voltage sensors 150 to ensure that the controller 160, multiple sets of resistance sensors 140 and multiple sets of voltage sensors 150 continue to work.

[0046] Figure 3 An external schematic diagram of a microgrid cable inspection and quick-connect cabinet provided for an exemplary embodiment of this application. (See diagram below.) Figure 3 As shown, the microgrid cable detection and quick-connect cabinet 100 may include a quick-connect device 180, which is located on the side wall of the cabinet 110. The quick-connect device 180 has multiple wiring ports 181, which are exposed on the outside of the cabinet 110. The multiple wiring ports 181 are electrically connected to multiple sets of detection terminals 120 respectively.

[0047] In practical applications, external cables can be electrically connected to multiple sets of detection terminals 120 via plug-in connectors 181, thereby connecting to the cables 130 inside the cabinet 110. In other words, when an external cable 130 is needed, the quick-connect device 180 can quickly connect the external cable to the internal cables 130 of the cabinet 110, eliminating the need for additional wiring work and effectively improving the connection efficiency of the cables 130.

[0048] like Figure 3 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include a power status light 190, a signal status light 210, and a control status light 220. The power status light 190, signal status light 210, and control status light 220 are all located on the outside of the cabinet 110, and the power status light 190, signal status light 210, and control status light 220 are all communicatively connected to the controller 160.

[0049] It should be noted that in practical applications, cable 130 typically includes power cables, signal cables, and control cables. By connecting the power cables, signal cables, and control cables to different sets of detection terminals 120, the continuity status of the power cables, signal cables, and control cables can be detected. Correspondingly, the power status light 190, signal status light 210, and control status light 220 can indicate the continuity status of the power cables, signal cables, and control cables, helping personnel to promptly determine whether there are faults in the power cables, signal cables, and control cables, effectively reducing the probability of safety accidents.

[0050] In one embodiment, if the power cable is in a normal connection state, the power status light 190 can be displayed as green; if the power cable is in an abnormal connection state, the power status light 190 can be displayed as red.

[0051] In one embodiment, if the signal cable is in a normal connection state, the signal status light 210 can be displayed as green; if the signal cable is in an abnormal connection state, the signal status light 210 can be displayed as red.

[0052] In one embodiment, if the connection status of the control cable is normal, the control status light 220 can be displayed as green; if the connection status of the control cable is abnormal, the control status light 220 can be displayed as red.

[0053] like Figure 3 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include an alarm light 230 and a buzzer 240. The alarm light 230 and the buzzer 240 are both located on the outer wall of the cabinet 110, and both the alarm light 230 and the buzzer 240 are communicatively connected to the controller 160.

[0054] In practical applications, when the contact resistance detected by the resistance sensor 140 is outside the preset resistance range, and / or the actual voltage detected by the voltage sensor 150 is outside the preset voltage range, the controller 160 can output a second signal indicating that the connection status of the cable 130 is abnormal. The controller 160 can control the alarm light 230 to flash (or change the display color of the alarm light 230, for example, from yellow to red), and can control the buzzer 240 to emit an alarm sound. This allows for timely alerting of personnel to troubleshoot the fault, effectively reducing the probability of safety accidents.

[0055] In one embodiment, the buzzer 240 can sound an intermittent alarm (e.g., sound for 1 second and stop for 0.5 seconds) to remind staff to troubleshoot the fault in a timely manner.

[0056] In one embodiment, the alarm light 230 being green indicates that the detection terminal 120 and the cable 130 are connected; the alarm light 230 being yellow indicates that the overall system is operating normally; and the alarm light 230 being red indicates that the system has malfunctioned.

[0057] like Figure 3 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include a display screen 250, which is located on the outer wall of the cabinet 110 and is communicatively connected to the controller 160.

[0058] In practical applications, the display screen 250 can display parameters such as the connection status of each group of cables 130, the contact resistance detected by each group of resistance sensors 140, and the actual voltage detected by each group of voltage sensors 150.

[0059] like Figure 3 As shown, the microgrid cable detection and quick-connect cabinet 100 may also include an emergency stop button 260, which is located on the outer wall of the cabinet 110.

[0060] In practical applications, when an emergency occurs, staff can cut off the internal circuit of cabinet 110 by operating emergency stop button 260, reducing the impact on the system.

[0061] like Figure 3 As shown, the cabinet 110 is provided with multiple heat dissipation holes 111. The heat dissipation holes 111 can realize ventilation and heat dissipation, which can ensure the air inside the cabinet 110 and the air outside can circulate with each other, and promptly dissipate the heat generated by the cable 130 during operation, so as to avoid the cable 130 from failing due to high temperature.

[0062] Figure 4 This is a flowchart illustrating a microgrid cable detection method provided in an exemplary embodiment of this application. The microgrid cable detection method provided in this embodiment can be applied to the microgrid cable detection described above and the controller in the quick-connect cabinet. Specifically, as... Figure 4 As shown, the microgrid cable inspection method may include: S410: Obtain the contact resistance and actual voltage between the cable and the test terminal.

[0063] Specifically, the contact resistance can be detected using the resistance sensor mentioned earlier. The actual voltage can be detected using the voltage sensor mentioned earlier.

[0064] S420: If the contact resistance is within the preset resistance range and the actual voltage is within the preset voltage range, output the first signal indicating that the cable is normal.

[0065] S430: If the contact resistance is outside the preset resistance range, and / or the actual voltage is outside the preset voltage range, output a second signal indicating a cable abnormality.

[0066] In one embodiment, the preset resistance range can be 5mΩ≤R≤10mΩ, where R represents the contact resistance; the preset voltage range can be 5V≤U≤10V, where U represents the actual voltage.

[0067] In one embodiment, when a second signal indicating a cable malfunction is output, the alarm light can be controlled to flash (or the display color of the alarm light can be changed, for example, from yellow to red), and the buzzer can be controlled to emit an alarm sound.

[0068] The microgrid cable testing method provided in this application has several advantages. First, it utilizes resistance and voltage sensors to test the connectivity of different types of cables within the same cabinet, eliminating the need for personnel to use multimeters or other tools to test each group individually. This effectively shortens testing time, improves testing efficiency, and reduces the workload of personnel. Second, it uses the contact resistance detected by the resistance sensor to determine whether there are problems such as looseness or oxidation between the cable and the test terminal, and uses the actual voltage detected by the voltage sensor to determine whether there are problems such as broken wires or short circuits in the cable. This allows for a comprehensive assessment of the cable connectivity, ensuring that the test results are accurate and reliable, and effectively improving the reliability of the test results.

[0069] like Figure 2 As shown, the controller 160 may include a processor 161 and a memory 162. Both the processor 161 and the memory 162 are located inside the cabinet. The processor 161 is communicatively connected to multiple sets of detection terminals, multiple sets of resistance sensors and multiple sets of voltage sensors. The memory 162 is communicatively connected to the processor 161 and can be used to store executable instructions of the processor 161.

[0070] The processor 161 may be a central processing unit (CPU) or other form of processing unit with data processing capabilities and / or instruction execution capabilities, and may control other components in the controller 160 to perform desired functions.
