[0060] The following is combined with Figure 1-22The present invention is further described.

[0061] Embodiment 1:

[0062] In order to solve the problems existing in the background technology, the present application proposes the following technical solutions: an online monitoring device for locating faults in power transmission lines, comprising an upper shell 1001 and a lower shell 100 that are detachably fixedly connected, the upper shell 1001 and the lower shell 100 are both semi-cylindrical cavity structures, and the upper shell 1001 and the lower shell 100 are fixedly connected by bolts, and the upper shell 1001 and the lower shell 100 are sleeved and fixed on the outside of the cable.

[0063] In addition, a monitoring control unit is provided in the lower housing 100, and a coil power supply module is provided in the monitoring control unit. The monitoring control unit includes a control box 200 fixedly connected in the lower housing 100, a power supply module 2001 and an induction coil 2003. The coil power supply module is a power supply coil 2002 fixedly connected in the lower housing 100. A processing control module, a time synchronization unit, a 4G communication module, and a storage module are provided in the control box 200. The 4G communication module, the storage module and the induction coil 2003 are electrically coupled to the processing control module. The time synchronization unit includes a GNSS timing module, a constant temperature crystal oscillator and a main control chip.

[0064] The induction coil 2003 is a Rogowski coil, the power module 2001 is a lithium battery, and the storage module is a common storage hard disk or a cloud storage system;

[0065] When a fault occurs in a transmission line, due to the influence of the conductor distribution parameters, a voltage traveling wave and a current traveling wave will be generated from the fault point and propagate to both ends along the transmission line. When a short circuit or lightning fault occurs in the transmission line, the fault traveling wave current generated has the characteristics of wide bandwidth and high amplitude, and can be monitored by using a Rogowski coil. On the transmission line, a device in this embodiment is installed every 30 km.

[0066] Among them, the principle of traveling wave monitoring is as follows Fig. 22 As shown;

[0067] Assume that the length of line MN is L, a fault occurs at point F of the line, and the initial traveling wave current at point M is i1;

[0068] The initial traveling wave current at point N is i2, the traveling wave current after i1 is reflected twice at point M and fault point F is i3, and the traveling wave current after i2 is reflected at point N and reaches point M is i4. The monitoring device in this embodiment is installed at points M and N;

[0069] By detecting and calibrating the time t1 and t2 when the initial traveling waves i1 and i2 reach M and N respectively, the distance between the measurement point and the fault point is:

[0070]

[0071] Thus, the location of the fault point can be accurately calculated, and v is the propagation speed of the traveling wave in the transmission line.

[0072] The above technical solution is further explained as follows: the center of the Rogowski coil passes through the measured transmission line. Due to the change of the current of the measured line, the magnetic field around the wire will change, thereby inducing a voltage signal representing the current characteristics on the Rogowski coil. In order to restore the current signal to be measured, the coil output voltage needs to be integrated, and the induced voltage signal is first filtered, integrated and then amplified, and finally input into the processing control module;

[0073] That is to say, the voltage is first raised after passing through the RC filtering protection circuit, the integration circuit, and the amplifier circuit, and finally transmitted to the processing control module. The RC filtering protection circuit, the integration circuit, and the amplifier circuit can be integrated into a circuit board installed in the control box 200, and the RC filtering protection circuit, the integration circuit, and the amplifier circuit are all existing technologies.

[0074] Further explanation is as follows: The main control module in the processing control module is preferably an STM32H743VIT6 single-chip microcomputer, which processes the data transmitted by the Rogowski coil in real time, and can also identify and store the traveling wave data in the collected data, and send the data to the mobile 4G communication module through serial communication, and transmit it to the background monitoring display terminal through the 4G communication module, thereby realizing remote wireless transmission of data.

[0075] Further explanation is as follows: In the identification of traveling wave data, since the wavelet modulus maximum of wavelet transform can correspond to the singular point of fault traveling wave signal, the traveling wave head can be identified by the wavelet transform modulus maximum method. However, this algorithm is an existing technology and will not be elaborated in this article.

[0076] Further explanation is as follows: Since it is necessary to know the arrival time of the fault traveling wave accurately, it is necessary to ensure time synchronization, use the second pulse signal of the satellite timing module to correct the constant temperature crystal oscillator clock signal in real time, and use the IRIG-B code to correct the absolute time scale, so as to achieve high-precision synchronization of the clocks between the traveling wave monitoring devices;

[0077] Therefore, the time synchronization unit includes a GNSS timing module, a constant temperature crystal oscillator and a main control chip.

[0078] The GNSS timing module uses QuectelL76C series chips. On the one hand, the second pulse signal and the clock signal of the constant temperature crystal oscillator are transmitted to different channels of the main control chip respectively, and the actual frequency of the signal is obtained by the frequency detector. On the other hand, the IRIG-B code pulse of the GNSS timing module is sent to the IRIG-B code decoder of the main control chip, and the absolute time scale containing time information is output. At the same time, the timer of the main control chip is corrected. The number of cycles that the constant temperature crystal oscillator needs to compensate is calculated by the actual frequency of the detected crystal oscillator and the actual frequency of the second pulse signal, so as to use the pulse regulator in the main control chip to divide the crystal oscillator signal to obtain a 1MHz standard signal, and send the standard pulse signal to the timer for counting, so as to obtain the time synchronized with the satellite in real time.

[0079] Among them, the control box 200 is provided with a front-end protection circuit module, an AC-DC rectifier filter circuit module, a wide voltage DC-DC conversion circuit module, a voltage detection and control circuit module, a charging circuit module, a BUCK conversion circuit module and a discharge power circuit module;

[0080] The front-end protection circuit module, AC-DC rectifier filter circuit module, wide voltage DC-DC conversion circuit module, voltage detection and control circuit module, charging circuit module, BUCK conversion circuit module and discharge power circuit module can be integrated and installed in the control box 200;

[0081] In addition, the front-end protection circuit, AC-DC rectification and filtering circuit, wide voltage DC-DC conversion circuit, voltage detection and control circuit, charging circuit, BUCK conversion circuit and discharge power circuit are all existing technologies.

[0082] Among them, the power taking coil 2002 stores the electricity in the power supply module 2001 after being processed by the front-end protection circuit module, AC-DC rectification and filtering circuit module, wide voltage DC-DC conversion circuit module, voltage detection and control circuit module and charging circuit module; the inductive power taking uses a current transformer as the energy taking structure, selects a power taking core made of silicon steel, and selects a suitable number of winding turns, which can be set according to different situations.

[0083] The flexible photovoltaic panel 400 (including the first photovoltaic panel 1002 and the second photovoltaic panel 30010 in the third embodiment) stores the electricity in the power module 2001 after being processed by the BUCK conversion circuit module, the voltage detection and control circuit module and the charging circuit module.

[0084] By setting up the discharge power circuit, it is convenient to provide current to various electrical components in the device.

[0085] Therefore, in practice, it also includes a background monitoring and display terminal, and the processing control module is connected to the background monitoring and display terminal through the 4G communication module.

[0086] In summary, the technology of traveling wave monitoring is an existing technology. This article only explains the corresponding theory. In specific practice, corresponding details can be supplemented as needed.

[0087] In this embodiment, since the device is installed at high altitude for a long time, in order to ensure the supply of power, the technical solution is further designed as follows:

In this embodiment, the welding frame 30018 is fixedly connected to both the left and right sides of the shell, and a first fixed plate 300 is fixedly connected to the outside of the welding frame 30018. A second fixed plate 3001 is provided on the outside of the first fixed plate 300, and a scissors-type telescopic assembly is provided between the first fixed plate 300 and the second fixed plate 3001.

[0089] Specifically, the scissor-type telescopic assembly includes a plurality of groups of first connecting rods 3004 and second connecting rods 3005 hinged to each other, the outside of the first fixed plate 300 is fixedly connected to the first guide rail 3002, the outside of the second fixed plate 3001 is fixedly connected to the second guide rail 3003, and the first guide rail 3002 and the second guide rail 3003 are both provided with a synchronization shaft 30016, and the outsides of the two synchronization shafts 30016 are respectively rotatably connected to the first roller 3006 and the second roller 3007, and the first guide rail 3002 and the second guide rail 3003 are respectively used for limiting and guiding the first roller 3006 and the second roller 3007.

When the first motor 30014 drives the threaded rod 30017 to rotate, the threaded rod 30017 drives the driving nut block 30015 to move linearly downward, thereby driving the synchronous shaft 30016 to move linearly downward, and then through the setting of the first connecting rod 3004 and the second connecting rod 3005, the second fixed plate 3001 can be moved outward and opened, and the second fixed plate 3001 drives the flexible photovoltaic panel 400 to open outward.
