The existing fault location technology of 10kV distribution line mainly relies on the fault recording function of the distribution automation terminal and the fault indicator device, but there are problems such as poor fault location accuracy, high system construction and operation cost, and easy damage of the device; the fault indicator also needs to be configured with a flow card, which has high long-term use cost and poor actual application effect.

[0033] In this embodiment, the control module, as the core component of the device, is responsible for coordinating and controlling the operation of other modules.

The addition of the fault location module allows the device to respond to faults more quickly, shortening fault handling time. Furthermore, the addition of the fault location module enables the device not only to detect and identify faults but also to accurately locate them, improving the intelligence level of fault handling.

[0038] Furthermore, such as Figure 2 As shown, in some embodiments, the device further includes a communication module 106, the first input terminal of the communication module 106 is connected to the output terminal of the signal generation module 102, the second input terminal of the communication module 106 is connected to the output terminal of the fault location module 105, the third input terminal of the communication module 106 is connected to the second output terminal of the fault identification module 104, and the output terminal of the communication module 106 is connected to a remote monitoring center.

[0039] Specifically, the communication module 106 is responsible for transmitting the device's output information to the remote monitoring center. It includes multiple input terminals connected to the output terminals of the signal generation module, fault location module, and fault identification module, respectively, and one output terminal connected to the remote monitoring center. The output terminal of the signal generation module is connected to the first input terminal of the communication module, allowing the communication module to receive signals with specific electrical characteristics generated by the signal generation module.

[0041] Further, in some embodiments, the signal generation module includes an adjustable inductive element and an adjustable capacitive element, the adjustable inductive element and the adjustable capacitive element are connected, and the adjustable inductive element is further connected with the target power distribution line.

[0042] Specifically, the signal generation module 102 in the embodiment can specifically include an adjustable inductive element and an adjustable capacitive element. For the adjustable inductive element, the inductive reactance through the target power distribution line is adjusted to generate a signal with specific frequency characteristics. The adjustable inductive element can specifically include an electronic adjustable inductor or a mechanical adjustable inductor, and its inductance value can be adjusted according to a control signal. Such adjustment can change the inductive reactance through the power distribution line, thereby affecting the frequency characteristics of the signal. After fault detection, the adjustable inductive element can adjust its inductance value according to the fault type to generate a signal with specific frequency characteristics, to help fault identification and positioning. For the adjustable capacitive element, the capacitive reactance through the target power distribution line is adjusted, and works with the adjustable inductive element to generate a signal with specific frequency characteristics. The adjustable capacitive element can include an electronic adjustable capacitor or a mechanical adjustable capacitor, and its capacitance value can be adjusted according to a control signal. Such adjustment can change the capacitive reactance through the power distribution line, and work with the adjustable inductive element to generate a signal with specific frequency characteristics. Adjustment of the capacitance value can further refine the frequency and phase characteristics of the signal to adapt to different fault detection and positioning requirements.

[0043] The signal generation module in this embodiment can flexibly generate signals with different electrical characteristics to adapt to the detection needs of various fault types and locations through adjustable inductance and capacitance elements. Signals with specific frequency characteristics can provide more information about the nature and location of the fault, thereby improving the accuracy of fault detection. The system can adjust the electrical characteristics of the signals according to the specific circumstances of the fault, enhancing the adaptability and flexibility of the system. By adjusting the frequency and phase characteristics of the signals, the fault point can be more accurately located, reducing the time and effort of troubleshooting. The automation and intelligent signal generation and adjustment reduce the need for human intervention, reducing maintenance costs and personnel safety risks. Accurate fault detection and localization help to quickly restore power supply, improving the reliability of the system and user satisfaction.

[0044] Further, in some embodiments, the control module includes a timing switch, the timing switch is connected to the fault detection module and the signal generation module respectively.

[0045] Specifically, the control module 103 in this embodiment can include a timing switch. After detecting that the target power distribution line has a fault based on the fault detection result, the timing switch is closed according to a preset time to control the signal generation module to start running.

[0046] Further, in some embodiments, the timing switch includes a relay unit and a timer unit, the relay unit is connected to the signal generation module and the target power distribution line respectively, and the timer unit is connected to the relay unit respectively.

[0047] Further, in some embodiments, the relay unit includes at least one relay, which is used to be in an open state when the target power distribution line is in normal operation, to isolate the power distribution line fault positioning auxiliary device from the target power distribution line.

[0048] Further, in some embodiments, the timer unit includes at least one timer, which is used to control the closing time of the relay.

[0049] Specifically, the timing switch in this embodiment can include a relay unit and a timer unit. When the target power distribution line is in normal operation, the relay unit is in an open state to isolate the power distribution line fault positioning auxiliary device from the target power distribution line. The relay unit is open during normal operation to protect the auxiliary device from high voltage impact. When a fault occurs, the relay unit is closed to allow the signal generation module to access the line and start working. The timer unit controls the closing time of the relay to make the signal generation module generate signals with specific electrical characteristics. The timer unit controls the closing time of the relay according to the preset time parameters. This ensures that the signal generation module works within a specific time window after a fault occurs to generate the necessary signals for fault identification.

[0050] The embodiment improves the timeliness of fault detection by precise control of the timing switch, so that the signal generation module can be accurately started at the critical moment after the fault occurs; during normal operation, the open state of the relay unit protects the auxiliary device from high voltage impact, prolonging the service life of the equipment; precise control of the timer unit ensures that the signal generation module works at the best time, and the generated signal can provide more information about the nature and location of the fault; the system can adjust the signal generation time according to the specific circumstances of the fault, enhancing the adaptability and flexibility of the system; by precisely controlling the signal generation time, the fault point can be more accurately located, reducing the time and workload of fault troubleshooting; automated and intelligent control reduces the need for human intervention, reducing maintenance costs and personnel safety risks; accurate fault detection and positioning help to quickly restore power supply, improving the reliability of the system and the satisfaction of users.

[0051] In order to facilitate understanding of the power distribution line fault positioning auxiliary device provided by the embodiment, a specific implementation of the power distribution line fault positioning auxiliary device is also provided, which includes an electromagnetic relay switch or similar functional module, composed of adjustable inductance, capacitance elements, and a timing switch module. The electromagnetic relay switch or similar functional module is in an open state during normal operation of the line, achieving hard isolation of the auxiliary device from the power distribution line to protect the auxiliary device electrical equipment from direct impact of high voltage on the line. After the line is shut down for a certain period of time, the electromagnetic relay switch or similar functional module is closed, the adjustable inductance and capacitance elements form a loop with the line, release an electrical signal with specific characteristics, and transmit it to the main station end fault recording equipment. By receiving the strength and presence or absence of electrical signals of different frequencies, the type and location of the fault can be indirectly determined. The timing switch module restores the electromagnetic relay switch or similar functional module to the open state after the adjustable inductance and capacitance elements release the electrical signal, to ensure that the auxiliary device is not impacted when the line is restored.

[0052] In a specific embodiment, as shown in Figure 3 At each branch point or certain distance point of the line, a power distribution line fault positioning auxiliary device (positioner) is installed, which can generate AC signals of different frequencies at each location through a frequency-adjustable resistor, thereby identifying the location. After installation, the power distribution line fault positioning auxiliary device automatically goes into operation as long as there is current passing through.

[0053] When the line fails, no current signal is detected in the power distribution line fault positioning auxiliary device used in the line, as shown in Figure 4The auxiliary device for fault positioning of power distribution line is shown. The internal relay of the auxiliary device for fault positioning of power distribution line turns on the circuit, and different frequency (position information) alternating current signals are fed back to the line through an alternating current booster. The alternating current booster includes a timer, a frequency modulation resistor and a voltage boosting and frequency modulation circuit. The missing positioner signal can be obtained by analyzing the alternating current information in the fault recording, so as to obtain the accurate fault position, greatly reduce the fault checking range, reduce the workload of fault site checking and shorten the power outage time.

[0054] In summary, the auxiliary device for fault positioning of power distribution line provided in the embodiment is mainly used for assisting in fault positioning of 10kV power distribution line. By monitoring the current and voltage state of the power distribution line in real time, the occurrence of fault can be quickly and accurately detected, the possibility of false positives and false negatives is reduced, the type and position of the fault can be quickly determined through the generated specific electrical characteristic signal, the fault checking and repair time is shortened, thereby reducing the need for manual patrol and manual detection through automatic fault detection and identification, reducing the operation and maintenance cost and personnel safety risk, and improving the efficiency and safety of line fault processing.
