The impedance of a cable is the sum of its resistivity and inductive reactance to AC signals, typically including resistance, inductance, and capacitance. In an ideal transmission system, the impedances of the two cables should be balanced to achieve maximum power transmission and minimum signal reflection.

[0057] As described in the background section, in modern power transmission and communication systems, split cables serve as the primary transmission medium, and the impedance characteristics at the junction of the two cables have a crucial impact on the performance of the entire power supply system. The impedance of a cable is the sum of its resistivity and inductive reactance to AC signals, typically including resistance, inductance, and capacitance. In an ideal transmission system, the impedances of the two cables should be balanced to achieve maximum power transmission and minimum signal reflection.

[0058] In traditional technology, impedance balancing of split cables is generally performed based solely on the cable condition. However, since split cables may be affected by various factors during power transmission, impedance balancing based solely on condition is inaccurate.

[0059] For the reasons mentioned above, the present invention provides a double-split cable connection impedance balancing system that can accurately balance impedance.

[0060] In one embodiment, such as Figure 1 As shown, a double-split cable connection impedance balancing system is provided, which includes an impedance detection device 10, a control device 20, and an impedance compensation device 30.

[0061] Impedance detection device 10 is used to perform impedance detection on the first cable and the second cable included in the double-split cable during the power transmission process of the double-split cable, and to determine the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable.

[0062] The control device 20 is used to acquire a first current impedance and a second current impedance, and based on the impedance difference between the first current impedance and the second current impedance, determine the compensation impedance for the second cable, and determine the target compensation unit that matches the compensation impedance from among the multiple impedance compensation units included in the impedance compensation device.

[0063] Impedance compensation device 30 is used to compensate the impedance of the second cable by adjusting the electrical parameters of the target compensation unit under the control of control device 20.

[0064] A cable is a conductor used to transmit power or signals, typically consisting of one or more insulated conductors and an outer insulation layer. A double-split cable is composed of two conductors connected in parallel. This structure gives double-split cables superior electrical performance compared to single-conductor cables, resulting in higher transmission capacity and better stability. Impedance detection device 10 refers to a device capable of detecting the impedance of a cable. For example, impedance detection device 10 can detect the voltage and current of the first and second cables in a double-split cable in real time, and calculate the first and second current impedances of the first and second cables respectively based on the collected voltage and current. Alternatively, it can directly detect the impedances of the first and second cables. Control device 20 is used to control actuators and collect sensor data. Specifically, in this application, control device 20 is the core of the system, responsible for receiving the first and second current impedances from impedance detection device 10, calculating the required compensation impedance, and controlling impedance compensation device 30 to adjust impedance compensation unit 31 to achieve precise impedance adjustment.

[0065] The control device 20 mainly includes the following parts:

[0066] The processor is responsible for processing the first and second current impedances transmitted from the impedance detection device 10, running preset impedance calculation and optimization algorithms, and calculating the required compensation impedance. The efficient operation of the processor is crucial to ensuring the system's real-time performance.

[0067] Control circuit: Based on the results calculated by the processor, a control signal is generated to control the impedance compensation device 30 to adjust the electrical parameters of the target compensation unit, ensuring that the system impedance matching reaches the optimal state.

[0068] Impedance compensation device 30 is a device that uses electrical equipment and circuits to improve the characteristics of a system, such as voltage, current, and power factor. It can adjust the impedance of the first cable and the second cable to achieve impedance matching and balance. The main task of impedance compensation device 30 is to compensate for impedance by adjusting the electrical parameters of the target compensation unit.

[0069] The first current impedance refers to the impedance of the first cable at the current moment. The second current impedance refers to the impedance of the second cable at the current moment. The compensation impedance refers to the impedance value used to compensate for the second cable. For example... Figure 2 As shown, the impedance compensation unit 31 may include, for example, an inductor unit 311, a capacitor unit 312, and a resistor unit 313, which can perform impedance compensation on the second cable. The target compensation unit refers to the impedance compensation unit 31 that is determined to match the compensation impedance. Electrical parameters refer to the electrical parameters of the impedance compensation unit 31, which may include, for example, energizing time, frequency, or current magnitude.

[0070] Specifically, during the power transmission process via cables, due to the impedance mismatch in the connection of the double-split cables, it is necessary to configure an impedance detection device 10 that can detect the impedance of the first cable and the second cable respectively, thereby determining the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable. Then, the control device 20 acquires the first current impedance and the second current impedance, compares the first current impedance and the second current impedance to obtain the impedance difference, thereby determining the compensation impedance for the second cable. Based on the compensation impedance, a target compensation unit matching the compensation impedance can be determined from the multiple impedance compensation units 31 included in the impedance compensation device 30, and the impedance compensation device 30 is controlled to adjust the electrical parameters of the target compensation unit, thereby achieving the purpose of impedance compensation for the second cable.

[0071] The aforementioned impedance balancing system for a double-split cable connection is configured with impedance detection equipment to perform impedance detection on the first and second cables of the double-split cable during power transmission, determining the first current impedance of the first cable and the second current impedance of the second cable. This system allows for the determination of the impedance of each cable within the double-split cable during power transmission. A control device is configured to acquire the first and second current impedances. Based on the impedance difference between the first and second current impedances, a compensation impedance for the second cable is determined. The system accurately determines the compensation impedance for the second cable based on the specific characteristics of the first and second current impedances. From the multiple impedance compensation units included in the impedance compensation device, a target compensation unit matching the compensation impedance is selected for targeted impedance compensation. Under the control of the control device, the impedance compensation device adjusts the electrical parameters of the target compensation unit to compensate the impedance of the second cable, thus achieving accurate impedance matching and balancing.

[0072] In one exemplary embodiment, such as Figure 3As shown, the impedance detection device 10 includes a signal acquisition module 11, an analog-to-digital conversion module 12, and a data processing module 13. The signal acquisition module 11 is used to detect electrical signals of the first cable and the second cable respectively, and determine the first current analog signal and the first voltage analog signal corresponding to the first cable, and the second current analog signal and the second voltage analog signal corresponding to the second cable. The analog-to-digital conversion module 12 is used to perform analog-to-digital conversion on the first current analog signal, the first voltage analog signal, the second current analog signal, and the second voltage analog signal respectively, to obtain the first current digital signal, the second voltage digital signal, the second current digital signal, and the second voltage digital signal. The data processing module 13 is used to perform signal analysis on the first current digital signal and the second voltage digital signal, and the second current digital signal and the second voltage digital signal respectively, to determine the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable.

[0073] The following are the analog signals for different currents: First analog current signal: The analog signal corresponding to the current in the first cable at the current moment. Second analog current signal: The analog signal corresponding to the current in the second cable at the current moment. First analog voltage signal: The analog signal corresponding to the voltage in the first cable at the current moment. Second analog voltage signal: The analog signal corresponding to the voltage in the second cable at the current moment. First digital current signal: The digital signal corresponding to the current in the first cable at the current moment. Second digital current signal: The digital signal corresponding to the current in the second cable at the current moment. First digital voltage signal: The digital signal corresponding to the voltage in the first cable at the current moment. Second digital voltage signal: The digital signal corresponding to the voltage in the second cable at the current moment.

[0074] Specifically, in determining the first and second current impedances, the signal acquisition module 11 first detects electrical signals in the first and second cables respectively to determine the first analog current signal and the first analog voltage signal corresponding to the first cable, and the second analog current signal and the second analog voltage signal corresponding to the second cable. To facilitate subsequent data processing, the analog signals are converted to digital signals using the analog-to-digital conversion module 12 to obtain the first digital current signal, the second digital voltage signal, the second digital current signal, and the second digital voltage signal. Then, the data processing module 13 analyzes these digital signals to determine the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable. For example, the signal acquisition module 11 may include a current sensor and a voltage sensor to detect electrical signals in the first and second cables respectively.

[0075] In this embodiment, the impedance detection device 10 includes a signal acquisition module 11, an analog-to-digital conversion module 12, and a data processing module 13, which can accurately detect the impedances of the first cable and the second cable respectively.

[0076] In one exemplary embodiment, such as Figure 2 As shown, the impedance compensation unit 31 includes an inductor unit 311, a capacitor unit 312, and a resistor unit 313; when the compensation impedance includes a compensation resistor, the control device 20 determines that the target compensation unit includes the resistor unit 313; when the compensation impedance includes a compensation reactance, the control device 20 determines that the target compensation unit includes at least one of the inductor unit 311 or the capacitor unit 312.

[0077] Among them, the inductor unit 311, also known as an inductor or coil, is a component capable of storing magnetic field energy. It is typically made of insulated wire wound on an insulated frame. The capacitor unit 312, also known as a capacitor, is a component capable of storing electric field energy. It consists of two or more mutually insulated metal plates filled with a dielectric material between the plates. The resistor unit 313, also known as a resistor, is a component that impedes the flow of electric current. It is typically made of a conductor, and its resistance value depends on the material, length, cross-sectional area, and temperature of the conductor.

[0078] Specifically, the process of compensating impedance mainly includes compensating resistor and reactance. The resistor corresponds to resistor unit 313, and the reactance corresponds to capacitor unit 312 and inductor unit 311. That is, when the compensation impedance includes compensation resistor, the control device 20 can determine that the target compensation unit includes resistor unit 313. When the compensation impedance includes compensation reactance, the control device 20 determines that the target compensation unit includes at least one of inductor unit 311 or capacitor unit 312.

[0079] In this embodiment, the control device 20 can determine the target compensation unit as at least one of the resistor unit 313, the inductor unit 311, or the capacitor unit 312 according to the specific compensation situation of the compensation impedance, so as to perform targeted impedance compensation on the second cable and thus ensure the accuracy of the impedance compensation process.

[0080] In an exemplary embodiment, the control device 20 is further configured to: obtain the updated impedance of the second cable after impedance compensation; and determine the updated compensation impedance of the second cable based on the updated impedance and the first current impedance.

[0081] The updated impedance refers to the updated impedance of the second cable after impedance compensation. The updated compensation impedance refers to the compensation impedance corresponding to the updated impedance.

[0082] Specifically, to ensure the system is always in optimal operating condition, the compensation impedance can be adjusted in real time according to changes in the cable's operating state. That is, after impedance compensation of the second cable, the control device 20 can obtain the updated impedance of the second cable after impedance compensation. Based on the updated impedance difference between the updated impedance and the first current impedance, the updated compensation impedance of the second cable is determined. Then, from the multiple impedance compensation units 31 included in the impedance compensation device 30, a target compensation unit matching the updated compensation impedance is selected, and the impedance compensation device 30 is controlled to adjust the electrical parameters of the target compensation unit to perform impedance compensation on the second cable again. It can be understood that the above steps can be repeated to ensure the system is always in optimal operating condition.

[0083] In one exemplary embodiment, such as Figure 4 As shown, the double-split cable connection impedance balancing system also includes an information storage device 40; the information storage device 40 is used to store the first current impedance, the second current impedance, and the compensation impedance.

[0084] Specifically, the double-split cable connection impedance balancing system also includes an information storage device 40 that can store the first current impedance, the second current impedance, and the compensation impedance, thereby storing the information involved in the double-split cable connection impedance balancing process so as to facilitate subsequent information traceability and ensure the stable progress of the double-split cable connection impedance balancing process.

[0085] In one exemplary embodiment, such as Figure 5 As shown, the double-split cable connection impedance balancing system also includes an alarm device 50; the alarm device 50 is used to monitor the first current impedance and the second current impedance, and outputs an alarm signal if at least one of the first current impedance and the second current impedance reaches an impedance threshold.

[0086] Among them, the impedance threshold refers to the threshold value set in advance for the impedance at the first cable or the second cable.

[0087] Specifically, an alarm device 50 can be configured to monitor the first current impedance and the second current impedance in real time. If at least one of the first current impedance and the second current impedance reaches the impedance threshold, it indicates that the impedance of the double-split cable is too strong and intervention is required, and an alarm signal needs to be fed back.

[0088] In this embodiment, an alarm device 50 is configured to monitor the first current impedance and the second current impedance. If at least one of the first current impedance and the second current impedance reaches an impedance threshold, an alarm signal is output. This can prevent cable damage caused by excessively high current impedance and ensure the normal operation of impedance balance in the dual-split cable connection.

[0089] In one exemplary embodiment, such as Figure 6 As shown, the double-split cable connection impedance balancing system also includes a power supply device 60; the power supply device 60 is connected to the impedance detection device 10, the control device 20, and the impedance compensation device 30; the power supply device 60 is used to supply power to the impedance detection device 10, the control device 20, and the impedance compensation device 30.

[0090] Among them, power supply equipment 60 can refer to equipment that can supply electrical power.

[0091] Specifically, in this embodiment, the power supply device 60 is connected to the impedance detection device 10, the control device 20, and the impedance compensation device 30, and can supply power to the impedance detection device 10, the control device 20, and the impedance compensation device 30.

[0092] In this embodiment, the power supply device 60 is configured to ensure the continuous operation of the impedance balance system of the double-split cable connection.

[0093] In one exemplary embodiment, such as Figure 7 As shown, the double-split cable connection impedance balancing system also includes a display device 70; the display device 70 is connected to the impedance detection device 10; the display device 70 is used to obtain and display the first current impedance and the second current impedance from the impedance detection device 10.

[0094] Among them, display device 70 refers to a device that has a display screen and can display information.

[0095] Specifically, in order to facilitate technicians to understand the specific impedance of the double-split cable in a timely manner, a display device 70 can be configured. The display device 70 can obtain and display the first current impedance and the second current impedance from the impedance detection device.

[0096] In this embodiment, a device with a display screen is configured to display information so that technicians can understand the specific impedance of the double-split cable in a timely manner.

[0097] In one exemplary embodiment, such as Figure 8 As shown, a method for impedance balancing in a double-split cable connection is also provided, the method comprising:

[0098] Step S802: During the power transmission process of the dual-split cable, obtain the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable;

[0099] Step S804: Based on the first current impedance and the second current impedance, and based on the impedance difference between the first current impedance and the second current impedance, determine the compensation impedance for the second cable.

[0100] Step S806: Determine the target compensation unit that matches the compensation impedance from among the multiple impedance compensation units included in the impedance compensation device.

[0101] In step S808, the impedance compensation device adjusts the electrical parameters of the target unit to compensate the impedance of the second cable.

[0102] Specifically, during the power transmission process of the double-split cable, due to the impedance mismatch between the first cable and the second cable, the first current impedance corresponding to the first cable and the second current impedance corresponding to the second cable can be obtained. The impedance difference between the first current impedance and the second current impedance can be compared to obtain the impedance difference, thereby determining the compensation impedance for the second cable. Based on the compensation impedance, a target compensation unit matching the compensation impedance can be determined from the multiple impedance compensation units included in the impedance compensation device. The impedance compensation device can then be controlled to adjust the electrical parameters of the target compensation unit, thereby achieving the purpose of impedance compensation for the second cable.

[0103] In one specific embodiment, an impedance balancing system for a double-split cable connection is provided. This system can detect the electrical parameters of the double-split cable in real time and adjust the impedance through a precise compensation mechanism to ensure system stability and transmission efficiency. The system integrates impedance detection equipment, impedance compensation equipment, and control equipment to automatically adjust the impedance of the second cable in the double-split cable and ensures continuous optimization of the compensation effect through a feedback mechanism.

[0132] Specific operating instructions:

[0133] This embodiment provides an impedance balancing control device for double-split cable connections, designed to optimize impedance matching in double-split cable connections and improve the performance of power transmission and communication systems. This device improves system transmission efficiency and stability through automated, real-time monitoring and dynamic adjustment of impedance values. This document details the functions of each module, installation steps, operation process, and the technical advantages of the device.

[0134] Basic components of the device:

[0135] The device mainly consists of three modules: an impedance detection device, an impedance compensation device, and a control device. Each module works together to achieve impedance equalization adjustment of the double-split cable connection impedance. The functions, composition, and synergistic effects of these modules in the overall system will be described in detail below.

[0136] System installation and hardware connection:

[0137] Installation of impedance testing equipment:

[0138] The impedance detection device is the front-end equipment of the system, responsible for monitoring the voltage and current of the first and second cables in real time and calculating the impedance value. Its main components include a voltage sensor, a current sensor, an analog-to-digital converter (ADC), and an impedance calculation unit.

[0139] Voltage sensor installation:

[0140] Voltage sensors are installed on both sides of the first and second cables, directly connected to both ends of the cables, ensuring that the voltage signals of the first and second cables can be captured. High-precision voltage sensors or voltage transformers can be selected to ensure measurement accuracy.

[0141] Select a suitable sensor fixing method based on the structure of the first and second cables to ensure that the sensor will not shift or loosen during actual use.

[0142] Current sensor installation:

[0143] Current sensors (such as Hall effect sensors or current transformers) should be installed on both the first and second cables to ensure continuous monitoring of current changes in the cables. Hall effect sensors are an ideal non-contact measurement method that can monitor current flow in the cable in real time without damaging the cable itself.

[0144] The physical contact or proximity between the current sensor and the cable needs to be kept stable to avoid signal fluctuations caused by loose installation.

[0145] Analog-to-digital converters (ADCs) and data processing:

[0146] The analog voltage and current signals acquired by the sensor are converted into digital signals by an analog-to-digital converter (ADC) for subsequent processing. The ADC needs to be reliably connected to the sensor to ensure that the signal is not distorted.

[0147] Where Z is the impedance, V is the voltage between the first and second cables, and I is the current.

[0148] Installation of impedance compensation equipment:

[0149] The impedance compensation device is responsible for compensating for impedance mismatches measured by the impedance detection device by adjusting the values ​​of inductors, capacitors, and resistors to achieve impedance balance. The main components of this module are an adjustable inductor, an adjustable capacitor, an adjustable resistor, and an adjustment control circuit.

[0150] Adjustable inductor:

[0151] An adjustable inductor is connected in the parallel branch of the cable. The main function of the inductor is to compensate for the inductive load of the second cable. Depending on the change in inductance value, it can reduce or increase the inductive impedance at the connection point.

[0152] Adjustable inductors can be precisely adjusted via electronic control to ensure the accuracy of the compensation effect.

[0153] Adjustable capacitor:

[0154] An adjustable capacitor is also connected to the parallel branch of the cable. The capacitor's function is to compensate for the capacitive load of the second cable. It compensates for capacitance mismatch in the cable system by adjusting the capacitance value.

[0155] When adjusting the capacitor, real-time monitoring of the overall impedance of the cable system should be maintained to prevent overcompensation or undercompensation.

[0156] Adjustable resistor:

[0157] The adjustable resistor is used to adjust the resistance of the second cable. By adjusting the resistance value, it compensates for resistance changes in the second cable caused by temperature variations or aging.

[0158] The installation of the adjustable resistor should ensure that it matches the resistance range of the second cable, avoiding exceeding the resistance adjustment range allowed by the system design.

[0159] Adjustment control circuit:

[0160] The adjustable components in the impedance compensation device are precisely controlled by an adjustment control circuit. The adjustment circuit receives control signals from the control device and adjusts the parameters of each adjustable component. Through an appropriate feedback mechanism, the adjustment control circuit ensures that the impedance value after each adjustment quickly reaches the set value.

[0161] Connection of control equipment:

[0162] The control equipment is the core component of the entire system. It is responsible for processing the data fed back from the impedance detection equipment, calculating the required compensation amount, and controlling the impedance compensation equipment to make corresponding adjustments. Its main components include a processor, control circuitry, and feedback mechanism.

[0163] Processor installation and connection:

[0164] The processor receives real-time data from the impedance sensing device, including voltage, current, and impedance values. Based on this data, the processor runs an impedance compensation algorithm to calculate the amount of compensation that needs to be adjusted.

[0165] The processor and the regulation control circuit are connected through a communication interface to ensure that the regulation signal can be transmitted in a timely manner.

[0166] Control circuit:

[0167] The control circuit generates precise control signals based on the compensation amount calculated by the processor, and adjusts the parameters of the adjustable inductor, adjustable capacitor and adjustable resistor respectively.

[0168] The connection between the control circuit and the impedance compensation device should be stable and able to respond quickly to control signals to ensure the response speed of the entire system.

[0169] Feedback mechanism:

[0170] The system's feedback mechanism monitors the compensated impedance value in real time using sensors and feeds the compensation effect back to the processor. If an impedance deviation is still detected, the processor will perform a second calculation to further adjust the compensation amount until the preset impedance balance target is achieved.

[0171] System operation process:

[0172] Impedance detection and calculation:

[0173] After the system starts up, the impedance detection device continuously monitors the voltage and current of the first and second cables to obtain real-time impedance values. The impedance detection device completes impedance measurement and calculation through the following steps:

[0174] The voltage sensor collects the voltage signals of the first and second cables, and the current sensor collects the current signals.

[0175] The analog-to-digital converter converts analog signals into digital signals and transmits the digital signals to the impedance calculation unit.

[0176] The impedance calculation unit calculates the current impedance value based on real-time data and transmits it to the control device.

[0177] Impedance compensation:

[0178] Based on the impedance value fed back by the impedance detection device, the control device calculates the required compensation amount through the processor:

[0179] The processor determines whether the current impedance matches the target impedance value. If there is a deviation, the processor determines the inductor, capacitor, and resistor values ​​that need to be adjusted according to a predetermined compensation algorithm.

[0180] The control circuit generates corresponding control signals to adjust the adjustable components of the impedance compensation device and adjust the impedance of the second cable.

[0181] After the impedance compensation device completes the adjustment, the system continues to monitor the impedance of the first and second cables to ensure that the adjusted impedance values ​​reach the preset range.

[0182] Feedback Adjustment and Adaptive Optimization

[0183] The system has an adaptive feedback mechanism that can continuously monitor the compensation effect and dynamically adjust the compensation amount.

[0184] The feedback mechanism monitors the compensated impedance value through sensors. If the impedance value still deviates from the target value, the processor will further adjust the compensation amount.

[0185] The feedback mechanism combines actual data to optimize the control strategy and ensure that the system can maintain impedance balance under different operating conditions.

[0186] Technical considerations during implementation:

[0187] High-precision sensor selection: The accuracy of the voltage and current sensors in impedance detection equipment directly affects the accuracy of impedance measurement results, so it is necessary to select suitable high-precision sensors.

[0188] Signal processing stability: When performing analog-to-digital converter (ADC) signal conversion, it is necessary to ensure signal integrity and avoid data distortion due to noise or interference.

[0189] Dynamic adjustment capability: Each component in the impedance compensation device needs to have good dynamic response capability, be able to adjust quickly according to the control signal, and ensure the real-time performance of impedance compensation.

[0190] To better illustrate the specific implementation of this embodiment, the system's workflow will be described in detail below:

[0191] The system first initializes the electrical parameters of the first and second cables using an impedance detection device. Voltage and current sensors then collect the voltage and current signals from the first and second cables. An ADC converts these analog signals into digital signals, which are then transmitted to the impedance calculation unit for analysis. The impedance calculation unit calculates the impedance values ​​of the first and second cables based on the formula Z = V / I.

[0192] The system enters real-time monitoring mode, and the impedance detection device continuously monitors the voltage and current of the first and second cables, transmitting the real-time data to the control device. The control device determines whether the impedance meets the preset matching value based on the detection data. If the impedance deviates from the target value, the system will automatically enter the compensation phase.

[0193] Upon receiving the adjustment signal from the control device, the impedance compensation device initiates the adjustment process of the adjustable inductor, capacitor, and resistor. The adjustment control circuit, based on the control signal, adjusts the parameters of the adjusting components, gradually adjusting the impedance of the second cable to the target value.

[0194] The system features a feedback mechanism that uses sensors to monitor the compensation effect in real time. If the compensation effect is unsatisfactory, the system dynamically adjusts the control signal and readjusts the compensation components until the impedance matching reaches the expected standard. This adaptive adjustment function ensures that the system maintains optimal performance under various operating environments.

[0195] The system records detailed data from each detection and compensation in a database and uploads it to a remote control center in real time via a communication module. Operators can monitor cable impedance changes through the remote control platform and manually adjust compensation settings when necessary.

[0196] The impedance balancing system for the double-split cable connection in this embodiment exhibits significant advantages in the following aspects:

[0197] High degree of automation: Through real-time detection and automatic compensation, the system can maintain impedance matching without human intervention, greatly improving work efficiency.

[0198] High-precision adjustment: Through precise adjustment of adjustable inductors, capacitors and resistors, the impedance of the first and second cables is kept at the optimal level, reducing signal reflection and energy loss.

[0199] High real-time performance: The system's feedback mechanism ensures a rapid response capability in the compensation process, enabling adjustments to impedance fluctuations in a very short time and ensuring system stability.

[0200] Wide adaptability: This invention is applicable to a variety of scenarios, including high-voltage power transmission systems, communication networks, and other applications requiring precise impedance matching. The system maintains stable performance regardless of extreme environmental conditions or complex cable networks.

[0201] The double-split cable connection impedance balancing system of this embodiment is suitable for power transmission systems, communication networks, and other scenarios requiring efficient and stable impedance matching. It can be widely used in urban power grids, long-distance transmission lines, data center communication networks, industrial automation control systems, etc., helping to improve system reliability and transmission efficiency.
