The first control circuit board 102 is provided with a first controller 103, a current sensor 104, a voltage sensor 105, and a first communication unit 106. The current sensor 104, the voltage sensor 105, and the first communication unit 106 are all electrically connected to the first controller 103. The first controller 103 is connected to a remote monitoring center 3 through the first communication unit 106. It should be noted that the first control circuit board can be placed inside the first housing, and its specific location and structure are not limited. An existing housing can be used. The current sensor, the voltage sensor, and the first communication unit can be connected to the first controller through pins, and their specific connection relationship and location are not limited, as long as data transmission can be achieved.

[0035] The fault location device 2 includes a second housing 201, which houses a pulse generating circuit 202, a pulse receiving circuit 203, a comparator 204, an AD converter 205, a CPLD 206, a second controller 207, and a second communication unit 208. The pulse generating circuit 202 generates pulse signals, which are received and identified by the pulse receiving circuit 203. The identified signals are connected to the CPLD 206 via the AD converter 205 and then to the second controller 207 via the CPLD 206. Simultaneously, the signals are directly connected to the second controller 207 via the comparator 204. The second controller 207 is connected to a remote monitoring center 3 via the second communication unit 208. It should be noted that the second control circuit board can be housed within the second housing; its specific location and structure are not limited, and existing housings can be used. The pulse generating circuit, pulse receiving circuit, comparator, AD converter, memory, CPLD, second controller, and second communication unit can be connected via pins; their specific connection relationships and locations are not limited, as long as data transmission is achieved.

[0036] The remote monitoring center 3 includes a PC and a server.

[0037] As a further option, the fault detection device 1 is distributed in a distributed manner in the self-closed through-running line.

[0038] As a further embodiment, the current sensor 104 is used to collect current data on the self-closing through-operation line, and the voltage sensor 105 is used to collect voltage data on the self-closing through-operation line.

[0039] As a further solution, the remote monitoring center 3 also includes an alarm device for alerting when a fault occurs.

[0040] As a further solution, both the first controller 103 and the second controller 207 adopt a single-chip microcomputer minimum system.

[0041] As a further embodiment, the microcontroller minimum system includes a microcontroller, a power supply circuit, a clock circuit, a reset circuit, and an interface circuit, all of which are electrically connected to the microcontroller.

[0042] As a further option, the microcontroller used is an STM32 series microcontroller.

[0043] As a further option, both the first communication unit 106 and the second communication unit 208 adopt 4G / 5G wireless communication modules.

[0044] As a further embodiment, a signal amplification circuit 4 and a filtering circuit 5 are provided between the current sensor 104, the voltage sensor 105 and the first controller 103.

[0045] As a further solution, the remote monitoring center 3 is also connected to the smart terminal 6.

[0046] In operation, the fault detection device 1 is installed in sections on the transmission line. The current sensor 104 and voltage sensor 105 collect the current and voltage values ​​of different areas of the transmission line in real time and transmit them to the first controller 103. The first controller 103 transmits the data to the PC for monitoring. When data abnormality occurs, it first determines which area of ​​the data is abnormal, and then uses the fault location device to accurately locate the fault point in the area of ​​data abnormality.

[0047] At one end of the line in the faulty area, a test pulse is sent to the cable under test using a pulse generator circuit 202. Upon encountering the fault point, the pulse is reflected back. The pulse receiver circuit 203 receives the returned signal, which is split into two paths: one enters a comparator, and the other enters an A / D converter 205. After entering the A / D converter 205, the signal is converted into a digital signal, processed by a CPLD 206, and then transmitted to a microcontroller. From there, it is transmitted to a PC via a second communication unit 208 as a graphical signal, displaying the waveform on the PC. The signal entering the comparator 204 is compared with a pre-designed threshold voltage, and a high or low level is output. If the signal voltage is greater than the threshold voltage, a traveling wave signal is considered to have been generated, and the comparator 204 outputs a high level. The CPLD 206 calculates the signal occurrence time and simultaneously transmits the time signal to the microcontroller. Upon receiving the high level, the microcontroller responds with an interrupt and waits for the CPLD 206 to transmit the time signal. Once the time signal is received, it immediately transmits it to the host computer and simultaneously returns from the interrupt. If the comparator outputs a low level, neither the CPLD 206 nor the microcontroller will perform any action. The PC calculates the distance between the measurement point and the fault point by using the time delay between the first positive voltage or current surge received at the measurement terminal and its reflected wave at the fault point.

[0048] Once the location of the fault is determined, the PC sends the data to the smart terminal, allowing staff to locate the fault in a timely manner, make corrections, and ensure normal power supply.

[0049] It should be noted that all functional modules used in this utility model are existing products, and their connection relationships are also conventional connection relationships in this field. They are not limited to specific models, as long as data transmission can be achieved.
