Description

Technical Field

[0001] This utility model relates to the field of power transmission line monitoring technology, specifically to an online monitoring device for power transmission lines based on inductive power extraction and solar power supply. Background Technology

[0002] Online monitoring devices for transmission lines are crucial equipment for ensuring the safe operation of the power grid. They provide data support for line condition assessment by collecting parameters such as conductor temperature, sag, and vibration in real time. Existing monitoring devices generally employ inductive power extraction, utilizing conductor current to generate induced electrical energy through a power extraction coil. However, when the line is under maintenance, operating under light load, or with low current, the induced magnetic field strength significantly weakens, causing the power extraction module to fail to output stable power, thus interrupting the monitoring function.

[0003] To overcome the above problems, some solutions use solar power as a supplement. However, in existing solar power solutions, the solar power module is an independent external module connected to the main body of the monitoring device via cables. This split structure not only increases the overall size and weight, but also makes the connecting cables prone to fatigue and breakage in strong winds due to differences in mechanical vibration between different components. Secondly, the external conductors are susceptible to induced current in the high electromagnetic interference environment of power transmission lines, posing risks of power transmission loss and signal interference.

[0004] Therefore, there is an urgent need for a solar power supply structure that can reliably supply power within a limited space. Utility Model Content

[0030] Detailed Implementation

[0031] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0032] This utility model discloses an online monitoring device for power transmission lines based on inductive power extraction and solar power supply. By integrating the solar panel with the housing, the reliability of power supply is significantly improved. It eliminates the connection cables and external supports of the split module, avoids the problem of wire fatigue breakage caused by component vibration differences in strong wind environments, replaces exposed wires with built-in circuits, and blocks the interference of induced current in the power transmission line through the electromagnetic shielding effect of the housing, ensuring the stability of power transmission and reducing the installation envelope volume.

[0033] According to the online monitoring device for transmission lines based on inductive power extraction and solar power supply provided by this utility model, such as Figure 1 , Figure 2As shown, the system includes an upper compartment 1 and a lower compartment 2, which are connected together by a hinge 3. The connecting wires between the components inside the upper compartment 1 and the components inside the lower compartment 2 are integrated into a connecting cable 4. In a top-view projection, the interfaces between the connecting cable 4 and the upper compartment 1, and between the connecting cable 4 and the lower compartment 2, are offset from the power transmission line. The upper and lower compartments are clamped onto the power transmission line and tightened together by four connecting bolts 5.

[0034] The upper compartment 1 houses an upper electromagnetic core assembly 103, and the lower compartment 2 houses a lower electromagnetic core assembly 207 corresponding to the upper electromagnetic core assembly 103. The upper and lower electromagnetic core assemblies 103 and 207 are arranged around the power transmission line for electromagnetic induction. A solar panel 101 is installed on the exterior of the upper compartment 1, outside the upper shell 102. The upper electromagnetic core assembly 103, lower electromagnetic core assembly 207, and solar panel 101 are all connected to functional modules inside the upper and lower compartments 1 and 2 via wires to power these modules. This invention integrates the solar panel 101 onto the exterior of the upper shell 102, enabling continuous power supply to electrical components during power outages or low-current scenarios. Its high integration makes it well-suited for wire monitoring, solving the problems of large space requirements and additional wiring associated with existing independently installed solar modules.

[0035] In a preferred example, such as Figure 3 , Figure 5 As shown, a power control module 108 is installed inside the upper compartment 1, and an energy storage module 210 is installed inside the lower compartment 2. The upper component 103 of the electromagnetic core, the lower component 207 of the electromagnetic core, and the solar panel 101 are all connected to the energy storage module 210 via wires. The power control module 108 is connected to the energy storage module 210 via wires, and the energy storage module 210 is connected to the functional module via wires. A rechargeable battery 211 is installed inside the lower compartment 2. The rechargeable battery 211 is connected to the energy storage module 210 via wires and also to the functional module via wires, for supplying power to the functional module. The energy storage module 210 serves as a transient energy buffer unit, used to quickly store the unstable electrical energy output by the solar panel 101, and is directly connected to the output terminal of the solar panel. The rechargeable battery 211 serves as a steady-state energy storage unit, used to store and release stable electrical energy over a long period, and is connected to the energy storage module 210 via a charging and discharging circuit, and is used to supply power to the functional module.

[0036] In a preferred embodiment, the outer surface of the upper shell 102 is cylindrical, with recessed mounting grooves forming grooves into which the solar panel 101 is embedded. A polytetrafluoroethylene (PTFE) film is attached to the outer surface of the solar panel 101. By covering the surface with the PTFE film, dust and other contaminants are difficult to adhere to, and its hydrophobic properties allow rainwater to roll off in a spherical shape rather than spreading into a water film, thereby reducing the risk of surface electrostatic discharge (SSD) on the shell.

[0037] In more preferred examples, such as Figure 1 , Figure 4 As shown, the solar panel 101 is fixed in the mounting groove on both sides by a first solar panel fixing block 111 and a second solar panel fixing block 117, respectively. The coordinated constraint of the solar panel 101 by the two fixing blocks enables rigid fixing and quick assembly / disassembly of the solar panel 101.

[0038] In a preferred embodiment, the lower electromagnet core assembly 207 is slidably mounted in a sliding fixing groove of the lower compartment 2. A spring 209 is installed between the top of the lower electromagnet core assembly 207 and the bottom of the sliding fixing groove. The spring 209 applies a pushing force to the lower electromagnet core assembly 207 toward the upper electromagnet core assembly 103. When the upper and lower compartments are closed, the upper electromagnet core assembly 103 is automatically balanced by the preload force of the spring 207, ensuring that the end faces of the two power extraction modules are tightly fitted together to ensure efficient inductive power extraction.

[0039] In a preferred example, such as Figure 3 , Figure 4 As shown, the functional modules inside the upper compartment 1 include a Rogowski coil 106, a temperature sensor 105, a communication module 107, a Beidou RTK antenna 109, and a GPRS antenna 110. The two ends of the Rogowski coil 106 are fixed to the upper compartment 1 and the lower compartment 2 respectively, used to collect real-time changes in conductor current and other electrical quantities, realizing conductor current measurement and fault recording functions. The Beidou RTK antenna 109 and the GPRS antenna 110 are installed outside the upper shell 102 and fixed by an antenna cover plate 116. The communication module 107 and the power control module 108 are both fixed inside the upper compartment 1 by an upper shell PCB cover plate 115. The magnetic core assembly 103 is fixed inside the upper compartment 1 by a magnetic core cover plate 113, and a sealing strip 114 is installed on the other side of the magnetic core cover plate 113.

[0040] like Figure 5As shown, the functional modules inside the lower compartment 2 include a camera module 202, an indicator light 203, a temperature, humidity and air pressure sensor 204, a buzzer 205, and a main control module 212. The camera module 202, indicator light 203, temperature, humidity and air pressure sensor 204, buzzer 205, and main control module 212 are all encapsulated inside the lower shell 201 by the lower shell cover plate 206. The upper shell 102 and the lower shell 201 are respectively equipped with a first wire adapter 104 and a second wire adapter 208 for clamping the power transmission line.
