Description

Technical Field

[0001] This application relates to the field of power transmission line de-icing technology, and in particular to a ground wire de-icing device, method and system. Background Technology

[0002] Overhead transmission lines are power lines erected above the ground, insulated by insulators and air. They typically consist of transmission conductors, overhead ground wires, insulator strings, towers, and grounding devices. Overhead transmission lines connect power plants, substations, and load points in different regions, transmitting or exchanging electrical energy to form power networks or distribution networks of various voltage levels. Because overhead lines are exposed to the atmosphere, they are directly affected by weather conditions. In cold weather, icing may occur on the lines, affecting power transmission. Therefore, de-icing of transmission lines has always been a key focus for maintenance personnel.

[0003] However, compared to transmission lines, ground wires, which do not carry out the task of transmitting electrical energy and therefore lack thermal efficiency, are more prone to icing. When ground wire icing reaches a certain level, insufficient sag can cause line discharge, leading to the interruption of power communication channels and threatening the safe operation of the power system.

Detailed Implementation

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0053] The core of this application is to provide a ground wire de-icing device, method, and system to achieve ground wire de-icing of overhead transmission lines, thereby ensuring the safe operation of the power system.

[0054] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0055] In overhead transmission lines, ground wires, unlike conductors, do not carry out the task of transmitting electrical energy and therefore lack current thermal efficiency, leading to more severe icing. This also makes it difficult for ground wires to absorb energy. When ground wire icing reaches a certain level, insufficient sag can cause line discharge, disrupting power communication channels, threatening the safe operation of the power system, and indirectly affecting daily life and production. Therefore, this application provides a ground wire de-icing device to perform ground wire de-icing tasks and ensure the safe operation of the power system.

[0056] Figure 1 This is a schematic diagram of a ground wire de-icing device provided in an embodiment of this application. Figure 1 As shown, the ground wire de-icing device includes: an electric pulse de-icing coil 2, a de-icing device communication and control circuit 3, and a pulse switching element 4;

[0057] The input terminal of the electric pulse de-icing coil is connected to the output terminal of the pulse switching element, and the electric pulse de-icing coil is in contact with the surface of ground wire 1;

[0058] The signal output terminal of the de-icing device's communication and control circuit is connected to the signal input terminal of the pulse switching element, used to receive control commands and send de-icing signals to the pulse switching element according to the control commands;

[0059] The input terminal of the pulse switching element is connected to the power supply and is used to control the conduction of the electric pulse de-icing coil and the power supply according to the de-icing signal, so as to perform the de-icing action to the ground wire.

[0060] Specifically, in this embodiment, the ground wire de-icing device is remotely controlled by the intelligent de-icing control system. The intelligent de-icing control system is a system that uniformly schedules the ground wire de-icing devices on overhead transmission lines. It can monitor the temperature and humidity of the overhead transmission lines in real time and issue control commands indicating ground wire de-icing to the ground wire de-icing devices so that the ground wire de-icing devices can perform subsequent de-icing operations.

[0061] It is understood that the de-icing device's communication and control circuit in the ground wire de-icing device establishes a communication connection with the intelligent de-icing control system. In this embodiment, the specific method of communication between the de-icing device's communication and control circuit and the intelligent de-icing control system is not limited. A communication connection can be established via 4G technology or 5G technology. Furthermore, the de-icing device's communication and control circuit and the intelligent de-icing control system can communicate using a Virtual Private Network (VPN) to ensure communication security, depending on the specific implementation. It should be noted that the de-icing device's communication and control circuit can receive control commands sent by the intelligent de-icing control system and can also periodically send self-test information of the ground wire de-icing device to the intelligent de-icing control system, including but not limited to the current temperature of the ground wire de-icing device, the status of each component, and its current location.

[0062] To remove ice from the ground wire, the device used in the ground wire de-icing system is an electric pulse de-icing coil. The electric pulse de-icing coil contacts the ground wire surface and vibrates upon receiving an electric pulse signal, causing the ice on the ground wire surface to fall off. In this embodiment, the input terminal of the electric pulse de-icing coil is connected to the output terminal of a pulse switching element, the signal output terminal of the de-icing device's communication and control circuit is connected to the signal input terminal of the pulse switching element, and the input terminal of the pulse switching element is connected to a power supply. When ground wire de-icing is required, the de-icing device's communication and control circuit receives a control command from the intelligent de-icing control system and sends a de-icing signal to the pulse switching element according to the control command. The pulse switching element controls the conduction of the electric pulse de-icing coil and the power supply based on the de-icing signal, thereby performing the de-icing action on the ground wire.

[0063] It should be noted that the specific structure of the electric pulse de-icing coil is not limited in this embodiment and depends on the specific implementation. In some embodiments, the electric pulse de-icing coil can be made by winding flat copper wire in a slotted wire groove. The cross-sectional dimensions of the flat copper wire can be 0.4mm × 2mm. When winding the coil, it can be folded 90 degrees at both ends of the wire groove to ensure that the coil is placed in the wire groove. At the same time, in order to increase the induced eddy current and improve the electric pulse force, a multiplier can also be set at the electric pulse de-icing coil. The multiplier can be made of a material with high conductivity and high hardness, such as AL6061-T6. In addition, the specific number of electric pulse de-icing coils is not limited in this embodiment and depends on the specific implementation. In some embodiments, in order to achieve a better de-icing effect, multiple electric pulse de-icing coils can be set in the ground wire de-icing device; multiple electric pulse de-icing coils completely wrap the surface of the ground wire, thereby improving the de-icing effect during vibration de-icing.

[0064] In specific implementations, the power supply provides electrical energy to the electrical pulse de-icing coil and the de-icing device's communication and control circuits. In this embodiment, the power supply method is not limited; it can be battery-powered or microwave wireless-powered, depending on the specific implementation. Furthermore, to insulate and mechanically support the components in the ground wire de-icing device, some embodiments may also include an insulating outer shell to enclose the components comprising the ground wire de-icing device.

[0065] In this embodiment, the ground wire de-icing device includes an electric pulse de-icing coil, a de-icing device communication and control circuit, and a pulse switching element. The input terminal of the electric pulse de-icing coil is connected to the output terminal of the pulse switching element, and the electric pulse de-icing coil is in contact with the ground wire surface. The signal output terminal of the de-icing device communication and control circuit is connected to the signal input terminal of the pulse switching element, used to receive control commands and send de-icing signals to the pulse switching element according to the control commands. The input terminal of the pulse switching element is connected to a power supply, used to control the conduction of the electric pulse de-icing coil and the power supply according to the de-icing signal, so as to perform the de-icing action on the ground wire. Therefore, in the above scheme, the electric pulse de-icing coil, in contact with the ground wire surface and controlled by the de-icing signal of the de-icing device communication and control circuit, can generate vibration after the power is turned on, thereby removing the ice on the ground wire surface. This reduces the labor cost of ground wire de-icing, prevents power communication channel interruptions caused by ground wire icing, and ensures the safe and stable operation of the entire transmission line.

Figure 2As shown, the ground wire de-icing device also includes: microwave receiving antenna 5, microwave rectifier receiving circuit 6, and energy storage capacitor 7.

[0067] The output of the microwave receiving antenna is connected to the input of the microwave rectifier receiving circuit to receive microwave energy and transmit it to the microwave rectifier receiving circuit.

[0068] The first output terminal of the microwave rectifier receiving circuit is connected to the input terminal of the de-icing device's communication and control circuit, and the second output terminal of the microwave rectifier receiving circuit is connected to the input terminal of the energy storage capacitor. This circuit is used to convert microwave energy into DC power and provide power to the de-icing device's communication and control circuit and the energy storage capacitor.

[0069] The output terminal of the energy storage capacitor is connected to the input terminal of the pulse switching element, and is used to provide electrical energy to the electric pulse de-icing coil under the control of the pulse switching element.

[0070] In practice, to provide power to the ground wire de-icing device more conveniently and stably, and to improve the de-icing efficiency of the ground wire de-icing device, a microwave receiving antenna, a microwave rectifier receiving circuit, and an energy storage capacitor are also installed in the ground wire de-icing device.

[0071] On one hand, the microwave receiving antenna can adopt a semi-circular ring design, with its output end connected to the input end of the microwave rectifier receiving circuit. The microwave rectifier receiving circuit can rectify the microwave signal energy received by the microwave receiving antenna into DC energy for use by the ground wire de-icing device. Specifically, the microwave rectifier receiving circuit transmits the rectified DC energy to the de-icing device's communication and control circuit and energy storage capacitor, supplying power to these components. The energy storage capacitor stores electrical energy, and its output end is connected to the input end of a pulse switching element, used to provide power to the electrical pulse de-icing coil under the control of the pulse switching element. On the other hand, to achieve insulation isolation from other components in the ground wire de-icing device and the atmospheric environment, the microwave receiving antenna, microwave rectifier receiving circuit, and energy storage capacitor can all be housed within an insulating casing 8.

[0072] It should be noted that the specific structure of the microwave rectifier receiving circuit is not limited in this embodiment and depends on the specific implementation. Furthermore, the source of the microwave signal received by the microwave receiving antenna is not limited in this embodiment; a separate microwave transmitter can be set up, or a microwave transmitter can be built based on the power transmission line, depending on the specific implementation. In this way, microwave wireless power supply for the ground wire de-icing device is realized, enabling a more convenient and stable supply of power to the ground wire de-icing device and improving its de-icing efficiency.

[0073] Figure 3 This is a schematic diagram of a microwave rectifier receiving circuit provided in an embodiment of this application. Based on the above embodiments, as a preferred embodiment, such as... Figure 3As shown, the microwave rectifier receiving circuit 6 includes: a filter circuit 9, a rectifier circuit 10, a first voltage regulator circuit 11, an energy storage circuit 12, and a boost circuit 13;

[0074] The output of the filter circuit is connected to the input of the rectifier circuit, the output of the rectifier circuit is connected to the input of the first voltage regulator circuit, the output of the first voltage regulator circuit is connected to the input of the energy storage circuit, and the first output of the energy storage circuit is connected to the input of the boost circuit.

[0075] The input terminal of the filter circuit serves as the input terminal of the microwave rectifier receiver circuit; the second output terminal of the energy storage circuit serves as the first output terminal of the microwave rectifier receiver circuit; and the output terminal of the boost circuit serves as the second output terminal of the microwave rectifier receiver circuit.

[0076] In practical implementation, the microwave rectifier receiving circuit includes a filter circuit, a rectifier circuit, a first voltage regulator circuit, an energy storage circuit, and a boost circuit. The filter circuit filters out unnecessary components from the received microwave signal, making the waveform smoother; the rectifier circuit converts microwave energy into DC power; the first voltage regulator circuit maintains a stable DC voltage to provide a stable DC power supply; the energy storage circuit improves power supply stability; and the boost circuit increases the DC voltage.

[0077] It should be noted that the second output terminal of the energy storage circuit serves as the first output terminal of the microwave rectifier receiving circuit and is connected to the input terminal of the de-icing device's communication and control circuit. In specific implementations, the DC power, after passing through the first voltage regulator circuit and the energy storage circuit, provides a stable and reliable 36VDC power supply to the de-icing device's communication and control circuit. The output terminal of the boost circuit serves as the second output terminal of the microwave rectifier receiving circuit and is connected to the input terminal of the energy storage capacitor. In specific implementations, the DC power, after passing through the boost circuit, provides a 1kV to 1.5kV DC high-voltage power supply to the energy storage capacitor. This embodiment does not impose restrictions on the specific structures of the filter circuit, rectifier circuit, first voltage regulator circuit, energy storage circuit, and boost circuit; the specific implementation will determine the appropriate structure.

[0078] In order to achieve self-powering of the ground wire de-icing device and reduce the difficulty of powering the ground wire de-icing device, based on the above embodiments, as a preferred embodiment, the ground wire de-icing device further includes: an energy harvesting device 14.

[0080] Figure 4This is a schematic diagram of the overall structure of the ground wire de-icing device provided in this embodiment of the application. The overhead transmission line includes transmission conductors and an overhead ground wire. Since the transmission conductors are responsible for transmitting electrical energy, energy can be extracted from the transmission conductors in specific implementations to power the ground wire de-icing device. For example... Figure 4 As shown, the electrical pulse de-icing coil and other components of the ground wire de-icing device are located on the ground wire; the energy harvesting device is located at the power transmission line, capable of harvesting the electrical energy from the power transmission line and converting it into microwave energy, which is then transmitted to the microwave receiving antenna of the ground wire de-icing device, thereby powering the ground wire de-icing device. It should be noted that the specific structure of the energy harvesting device is not limited in this embodiment and depends on the specific implementation.

[0083] The input terminal of the conversion circuit is connected to the energy extraction port of the output winding, and is used to convert the electrical energy of the transmission line into microwave energy and send it to the microwave receiving antenna.

[0084] A current transformer is a device that converts a large primary current into a small secondary current based on the principle of electromagnetic induction. The closed iron core of the current transformer passes through a power transmission conductor. Since the conductor transmits alternating current, it acts as the primary winding, thus generating an induced current in the closed iron core. The output winding is wound around the closed iron core of the current transformer, extracting electrical energy from the core and inputting it to the conversion circuit through an energy extraction interface. The conversion circuit converts the electrical energy into microwave energy and transmits it to a microwave receiving antenna.

[0087] In practical implementation, the first and second ends of the primary winding of the transformer are connected to the energy extraction ports of the output winding as input terminals of the conversion circuit, transmitting AC power to the bridge rectifier circuit. The bridge rectifier circuit converts the AC power into DC power and transmits it to the second voltage regulator circuit, which regulates the DC power. The DC / DC circuit further regulates the DC voltage and transmits the regulated DC power to the microwave power amplifier. It is important to note that the regulated DC power not only serves as the microwave signal source but also powers the microwave power amplifier; the microwave power amplifier converts the DC power into microwave energy and amplifies it to reduce microwave transmission losses; finally, it is transmitted through a microwave transmitting antenna.

[0088] Figure 7 This is a schematic diagram of another conversion circuit provided in an embodiment of this application.

[0096] In practice, the de-icing device's communication and control circuit monitors and represents the control command for de-icing the ground wire in real time. When a control command is received, the de-icing device's communication and control circuit sends a de-icing signal to the pulse switching element according to the control command. After receiving the de-icing signal, the pulse switching element controls the electric pulse de-icing coil to conduct with the power supply, thereby causing the electric pulse de-icing coil to vibrate; since the electric pulse de-icing coil is in contact with the ground wire surface, it can perform the de-icing action on the ground wire.

[0097] In this embodiment, the control command for de-icing the ground wire is monitored and characterized. When the control command is received, a de-icing signal is sent to the pulse switching element according to the control command. The pulse switching element controls the electric pulse de-icing coil to conduct with the power supply, thereby performing the de-icing action on the ground wire. Therefore, in the above scheme, the electric pulse de-icing coil, in contact with the ground wire surface and controlled by the de-icing signal of the de-icer's communication and control circuit, can generate vibration after the power is turned on, thereby removing the ice on the ground wire surface. This reduces the labor cost of ground wire de-icing, prevents power communication channel interruptions caused by ground wire icing, and ensures the safe and stable operation of the entire transmission line.

[0098] In the above embodiments, the de-icing method has been described in detail. This application also provides embodiments of the de-icing system.

[0100] The monitoring module 40 is used to monitor and characterize the control commands for de-icing the ground wire.

[0101] The transmitting module 41 is used to send a de-icing signal to the pulse switching element according to the control command when a control command is received, so that the pulse switching element can control the electric pulse de-icing coil to conduct with the power supply and perform the de-icing action to the ground wire.

[0102] In this embodiment, the ground wire de-icing system includes a monitoring module and a transmitting module. During operation, the ground wire de-icing system can implement all the steps of the aforementioned ground wire de-icing method. Monitoring is used to characterize the control commands for de-icing the ground wire. When a control command is received, a de-icing signal is sent to a pulse switching element, which then controls the electric pulse de-icing coil to connect to the power supply, executing the de-icing action on the ground wire. Therefore, in the above scheme, the electric pulse de-icing coil, in contact with the ground wire surface and controlled by the de-icing signal from the de-icing device's communication and control circuit, can generate vibration after power is switched on, thereby removing the ice buildup on the ground wire surface. This reduces the labor costs of ground wire de-icing, prevents power communication channel interruptions caused by ground wire icing, and ensures the safe and stable operation of the entire transmission line.
