Description

Technical Field

[0001] This application relates to the field of high-voltage transmission line technology in power systems, and in particular to a metal particle capture system and method for AC gas-insulated transmission pipelines. Background Technology

[0002] Since the 1960s and 70s, with the development of gas insulation technology, GIL (Gas-insulated Metal Enclosed Transmission Line) has been widely used around the world and has great application prospects in the fields of ultra-high voltage power transmission and special power transmission corridors.

[0003] my country started building gas-insulated power transmission pipelines relatively late, but with the development of long-distance, high-capacity, high-voltage power transmission, transmission corridors will inevitably pass through special terrains such as mountains and lakes. At the same time, with the accelerated urbanization in my country, electromagnetic radiation near power transmission corridors also needs to be strictly controlled. Therefore, my country's gas-insulated power transmission technology has developed rapidly in recent years.

[0004] In a gas-insulator (GIL), metal particles are one of the main factors causing electric field distortion and insulation breakdown. Moving metal particles can cause air gap breakdown, while metal particles attached to or moving near the insulator surface can introduce charges onto the insulator surface, distorting the original electric field and affecting the normal operation of the GIL.

[0005] The relevant technologies mainly suppress particles in AC GILs by using particle traps. However, in these technologies, the trajectory of metal particles is difficult to control. When metal particles touch high-voltage conductors, the possibility of flashover in GILs increases. Furthermore, the particle traps have poor particle capture efficiency and need to be improved. Summary of the Invention

[0006] This application provides a metal particle capture system and method for AC gas insulated power transmission pipelines to solve the technical problems in related technologies, such as the difficulty in controlling the movement trajectory of metal particles, which increases the possibility of flashover in GIL, and the poor particle capture efficiency of particle traps.

[0007] The first aspect of this application provides a metal particle capture system for an AC gas-insulated power transmission pipeline, comprising: a plurality of traps for capturing metal particles; an introducer for introducing a corresponding preset unidirectional magnetic field in different regions inside the AC gas-insulated power transmission pipeline; and a controller for controlling the introducer to introduce the preset unidirectional magnetic field when the metal particles are moving, thereby inducing the metal particles to move directionally away from the basin insulator through the magnetic field, so that the metal particles fall into the plurality of traps.

[0008] Optionally, in one embodiment of this application, the introducer is an electromagnet.

[0009] Optionally, in one embodiment of this application, the introducer is a device that applies a changing magnetic field.

[0010] Optionally, in one embodiment of this application, the direction of the magnetic field is set to correspond to the direction of motion of the metal particles in the corresponding region, and the strength of the magnetic field is set to correspond to the velocity of the metal particles.

[0011] Optionally, in one embodiment of this application, each of the plurality of traps is positioned at the midpoint of each section of the AC gas-insulated transmission pipeline to trap the metal particles at the midpoint between two insulators using a particle trap.

[0012] A second aspect of this application provides a method for capturing metal particles in an AC gas-insulated power transmission pipeline, comprising the following steps: detecting whether the metal particles are moving; when the movement of the metal particles is detected, introducing a preset unidirectional magnetic field, and inducing the metal particles to move away from the basin insulator through the magnetic field, so that the metal particles in the AC gas-insulated power transmission pipeline fall into the plurality of capture devices.

[0013] Optionally, in one embodiment of this application, before introducing the preset single-direction distributed magnetic field, the method further includes: setting the direction of the magnetic field to correspond to the movement direction of the metal particles in the corresponding region, and setting the intensity of the magnetic field to correspond to the velocity of the metal particles.

[0014] Optionally, in one embodiment of this application, before introducing the preset unidirectional magnetic field, the method further includes: setting each of the plurality of traps at the middle position of each section of the DC gas-insulated transmission pipeline to trap the metal particles at the middle position of the two insulators using a particle trap.

[0015] A third aspect of this application provides an electronic device, including: a memory, a processor, and a computer program stored in the memory and executable on the processor, wherein the processor executes the program to implement the method for capturing metal particles in an AC gas-insulated power transmission pipeline as described in the above embodiments.

[0016] A fourth aspect of this application provides a computer-readable storage medium storing a computer program that, when executed by a processor, implements the above-described method for capturing metal particles in an AC gas-insulated power transmission pipeline.

[0017] This application embodiment, based on an introducer, achieves directional movement of particles through an external magnetic field. This allows the particles to move in an approximately semi-circular horizontal direction close to the electrode surface and ultimately be captured by the trap, thereby suppressing the particle's take-off height, preventing the particles from contacting the high-voltage conductor, and improving the operational stability of the GIL and the particle capture efficiency. This solves the technical problems in related technologies where the difficulty in controlling the trajectory of metal particles increases the possibility of flashover in the GIL, and the particle trap has poor particle capture efficiency.

[0032] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0033] The following description, with reference to the accompanying drawings, illustrates a metal particle capture system and method for AC gas-insulated power transmission pipelines according to embodiments of this application. Addressing the technical problems mentioned in the background section of the related art, where the movement trajectory of metal particles is difficult to control, increasing the possibility of flashover in the gas-insulated transmission line (GIL), and where particle traps have poor particle capture efficiency, this application provides a metal particle capture system for AC gas-insulated power transmission pipelines. In this system, based on an introducer, an external magnetic field is applied to achieve directional movement of particles, allowing the particles to move in an approximately semi-circular horizontal direction close to the electrode surface and ultimately be captured by the trap. This suppresses the particle's take-off height, prevents particles from contacting the high-voltage conductor, and improves the operational stability of the GIL and the particle capture efficiency. Therefore, this solves the technical problems in the related art, where the movement trajectory of metal particles is difficult to control, increasing the possibility of flashover in the GIL, and where particle traps have poor particle capture efficiency.

[0034] Specifically, Figure 1 This is a schematic diagram of a metal particle capture system for an AC gas-insulated power transmission pipeline provided in an embodiment of this application.

[0035] like Figure 1As shown, the metal particle capture system for the AC gas-insulated power transmission pipeline includes: multiple traps 100, an inlet 200, and a controller 300.

[0036] Specifically, multiple traps 100 are used to capture metal particles.

[0037] It is understandable that due to material aging and wear, there are metal particles in the gas-insulated pipes. The sources of charge on the metal particles are mainly three: conduction through conductors or coating media; micro-discharge between particles and electrodes; and corona discharge at the tip of the particles.

[0038] When metal particles are charged, they will move due to the force in the electric field. The motion characteristics will vary depending on the force. From the perspective of the particle's location, the particles can be divided into two types: particles on the electrode surface and particles in the air gap.

[0039] Force analysis can be as follows Figure 2 As shown, G is the particle's gravity, Fq is the Coulomb force exerted by the electric field on the particle, and v is the particle's direction of motion.

[0040] like Figure 3 As shown, under AC conditions, the charged forces on the particles become complex with the continuous change of the applied voltage. The particles repeatedly and irregularly jump within the cavity gaps. Some particles gradually move closer to the insulator, while others gradually move away from it. Simultaneously, the particles move irregularly in the radial direction of the cavity, gradually distributing themselves onto the lower half of the cavity surface. As the particles disperse, the number of jumping particles gradually decreases.

[0041] In summary, the vertical movement of metal particles during their motion shortens the gas insulation distance between the two electrodes, increasing the possibility of discharge breakdown.

[0042] Therefore, multiple traps 100 are needed to capture metal particles in the gas-insulated pipeline to avoid insulation flashover caused by the reciprocating motion of particles between conductors, thereby greatly improving the operational stability of GIL.

[0043] Optionally, in one embodiment of this application, each of the plurality of traps 100 is positioned at the midpoint of each section of the AC gas-insulated transmission pipeline to trap metal particles at the midpoint between two insulators using a particulate trap.

[0044] In actual implementation, such as Figure 4As shown, in this embodiment of the application, a gas-insulated transmission pipeline between two adjacent insulators can be defined as a section of GIL, with a reference length of 6m. In this embodiment of the application, a trap 100 can be placed in the middle of each GIL section, that is, a metal particle trap 100 used in conventional AC GILs. Its principle is to form a low electric field area to trap the surrounding metal particles.

[0045] Furthermore, in this embodiment of the application, the segment of GIL where the catcher 100 is located can be defined as a non-a region; the area between two adjacent non-a regions can be defined as an a region, and each a region contains an insulator.

[0046] In this embodiment, each of the multiple traps 100 can be positioned at the middle of each section of the DC gas-insulated transmission pipeline to trap metal particles at the middle of two insulators, thereby reducing the number of metal particles near the insulators.

[0047] The introducer 200 is used to introduce a corresponding preset unidirectional magnetic field in different regions inside the AC gas-insulated power transmission pipeline.

[0048] Those skilled in the art will understand that once metal particles begin to move, in addition to being subject to their own gravity and the electric field force generated under normal operation of the transmission line, they are also subject to the Lorentz force under the influence of the magnetic field. Since the Lorentz force is perpendicular to the direction of particle movement and increases with the increase of speed, it reduces the height of the particle moving towards the high-voltage conductor, causing the particle to closely adhere to the ground and make a unidirectional semi-circular motion near the grounding shell. Therefore, in this embodiment, the introducer 200 can introduce corresponding preset unidirectional magnetic fields in different areas inside the AC gas insulated transmission pipeline to control the horizontal movement direction of the particles, thereby facilitating the capture of metal particles and keeping the particles away from the insulator.

[0049] Optionally, in one embodiment of this application, the introducer 200 is an electromagnet.

[0050] In some embodiments, the introducer 200 can be an electromagnet, thereby ensuring the stability of the magnetic field introduced by the introducer 200 and thus increasing the stability of the embodiments of this application.

[0051] Optionally, in one embodiment of this application, the introducer 200 is a device that applies a changing magnetic field.

[0052] In other embodiments, the introducer 200 may also be a device that applies a changing magnetic field, thereby introducing a corresponding preset unidirectional magnetic field in different regions inside the pipe, and inducing metal particles through magnetic force to achieve capture.

[0053] Optionally, in one embodiment of this application, the direction of the magnetic field is set to correspond to the direction of motion of the metal particles in the corresponding region, and the strength of the magnetic field is set to correspond to the velocity of the metal particles.

[0054] Specifically, such as Figure 5 As shown, in this embodiment of the application, a magnetic field perpendicular to the paper and pointing outwards can be applied to the part of the insulator projected onto the shell (extending to the right edge of region a) on the side of the insulator closest to the shell; conversely, in this embodiment of the application, a magnetic field perpendicular to the paper and pointing inwards can be applied to the part of the insulator projected onto the inner conductor (extending to the left edge of region a) on the side of the insulator closest to the inner conductor (extending to the left edge of region a).

[0055] Furthermore, such as Figure 6 As shown, taking a negatively polarized metal particle moving upward as an example, it is subjected to a downward gravitational force and an electric field force pointing towards the inner conductor. By using the right-hand rule, it can be determined that the metal particle is subjected to a Lorentz magnetic force away from the insulator.

[0056] The controller 300 is used to control the introducer 200 to introduce a preset unidirectional magnetic field when the metal particles are moving. The magnetic field induces the metal particles to move away from the basin insulator in a directional manner, so that the metal particles fall into multiple traps 100.

[0057] In actual implementation, take an example of negatively polar metal particles moving upwards:

[0058] 1) One exercise

[0059] like Figure 7 As shown, the controller 300 can control the introducer 200 to introduce a preset unidirectional magnetic field. The metal particles start from the shell, have negative polarity, and move upward. Due to the action of electric field force, gravity, and Lorentz force, they move away from the insulator and eventually fall into the metal particle trap (non-A region).

[0060] It is important to note that during the motion, because the upward acceleration of the particles is very small, the metal particles cannot possibly come into contact with the high-voltage conductor. As can be seen from the formula F = QvB, the greater the speed, the stronger the magnetic force, and the greater the probability that the particles will move downwards.

[0061] Therefore, the particles would originally accelerate towards the high-voltage conductor. After the magnetic field is applied, the particles can only move in an approximately semi-circular horizontal direction close to the electrode surface and gradually fly towards the trap 100.

[0062] 2) Multiple exercises

[0063] like Figure 8 and Figure 9As shown, the controller 300 can control the introducer 200 to introduce a preset magnetic field distributed in a single direction. The metal particles start from the shell, have negative polarity, and move upward. Because the acceleration of the particles moving upward is very small, and the Lorentz magnetic force perpendicular to the direction of particle movement and away from the insulator is constantly increasing, the upward velocity component of the particles decreases to 0 during the upward movement, and the particles begin to move downward due to gravity.

[0064] If the particle velocity is appropriate at this time, it will stop in the particle trap zone as mentioned above;

[0065] If the particle speed is low at this time, the metal particle falls into the original insulator region a, collides with the outer shell and jumps up. Due to the Lorentz magnetic force, the metal particle moves away from the insulator again until it falls completely into the trap.

[0066] If the particle velocity is high at this time, the metal particle passes through the metal particle trap (non-region a) and collides with the outer shell in region a of another insulator. Due to the Lorentz force, the metal particle moves away from the insulator again until it falls completely into the trap.

[0067] In summary, the embodiments of this application can actively intervene in the trajectory of particles by applying an external magnetic field. The particles can only move in an approximately semi-circular horizontal direction close to the electrode surface and gradually fly towards the trap 100. Under the normal operation of the gas-insulated power transmission pipeline, the metal particles are captured, avoiding damage to the insulation by the metal particles. This not only suppresses the ionization phenomenon of space charge introduced by the particles during the movement, but also suppresses the jumping height of the particles, preventing the particles from contacting the high-voltage conductor. This reduces the possibility of flashover induced by the particles approaching the high-voltage conductor and improves the operational stability of the GIL.

[0068] Combination Figures 2 to 10 As shown, the working principle of the metal particle capture system 10 for AC gas-insulated power transmission pipelines according to an embodiment of this application will be described in detail.

[0069] like Figure 10 The diagram shown is a cross-sectional view of an embodiment of this application. In this embodiment, under the condition that the metal particles and the central conductor have the same polarity and the charge remains unchanged, the metal particles are moved away from the basin insulator by an external magnetic field. Finally, a particle trap, i.e., a trapper 100, is used to capture the particles in the middle position of the two insulators.

[0070] In actual implementation, the working principle of the embodiments of this application can be explained by analyzing the forces and trajectories of the metal particles.

[0071] 1) Basic force analysis of metal particles (without applied magnetic field)

[0072] It is understandable that due to material aging and wear, there are metal particles in the gas-insulated pipes. The sources of charge on the metal particles are mainly three: conduction through conductors or coating media; micro-discharge between particles and electrodes; and corona discharge at the tip of the particles.

[0073] When metal particles are charged, they will move due to the force in the electric field. The motion characteristics will vary depending on the force. From the perspective of the particle's location, the particles can be divided into two types: particles on the electrode surface and particles in the air gap.

[0074] Force analysis can be as follows Figure 2 As shown, G is the particle's gravity, Fq is the Coulomb force exerted by the electric field on the particle, and v is the particle's direction of motion.

[0075] 2) Analysis of the basic motion trajectory of metal particles (without applied magnetic field)

[0076] like Figure 3 As shown, under AC conditions, the charged forces on the particles become complex with the continuous change of the applied voltage. The particles repeatedly and irregularly jump within the cavity gaps. Some particles gradually move closer to the insulator, while others gradually move away from it. Simultaneously, the particles move irregularly in the radial direction of the cavity, gradually distributing themselves onto the lower half of the cavity surface. As the particles disperse, the number of jumping particles gradually decreases.

[0077] In summary, the vertical movement of metal particles during their motion shortens the gas insulation distance between the two electrodes, increasing the possibility of discharge breakdown, while the horizontal movement of metal particles is irregular.

[0078] For convenience, in the embodiments of this application, when considering the basic motion of metal movement, the left-right motion can be ignored, and the focus can be on its up-down motion.

[0079] 3) Apply a magnetic field

[0080] like Figure 4 As shown, in this embodiment of the application, a gas-insulated transmission pipeline between two adjacent insulators can be defined as a section of GIL, with a reference length of 6m. In this embodiment of the application, a trap 100 can be placed in the middle of each GIL section, that is, a metal particle trap 100 used in conventional AC GILs. Its principle is to form a low electric field area to trap the surrounding metal particles.

[0081] Furthermore, in this embodiment of the application, the segment of GIL where the catcher 100 is located can be defined as a non-a region; the area between two adjacent non-a regions can be defined as an a region, and each a region contains an insulator.

[0082] Specifically, such as Figure 5As shown, in this embodiment of the application, a magnetic field perpendicular to the paper and pointing outwards can be applied to the part of the insulator projected onto the shell (extending to the right edge of region a) on the side of the insulator closest to the shell; conversely, in this embodiment of the application, a magnetic field perpendicular to the paper and pointing inwards can be applied to the part of the insulator projected onto the inner conductor (extending to the left edge of region a) on the side of the insulator closest to the inner conductor (extending to the left edge of region a).

[0083] 4) Force analysis of metal particles (applied magnetic field)

[0084] Furthermore, such as Figure 6 As shown, taking a negatively polarized metal particle moving upward as an example, it is subjected to a downward gravitational force and an electric field force pointing towards the inner conductor. By using the right-hand rule, it can be determined that the metal particle is subjected to a Lorentz magnetic force away from the insulator.

[0085] 5) Analysis of the trajectory of metal particles (with applied magnetic field)

[0086] In actual implementation, take an example of negatively polar metal particles moving upwards:

[0087] a) One exercise

[0088] like Figure 7 As shown, the metal particles start from the outer shell, have a negative polarity, and move upward. Due to the influence of electric field force, gravity, and Lorentz force, they move away from the insulator and eventually fall into the metal particle trap (non-region a).

[0089] It is important to note that during the motion, because the upward acceleration of the particles is very small, the metal particles cannot possibly come into contact with the high-voltage conductor. As can be seen from the formula F = QvB, the greater the speed, the stronger the magnetic force, and the greater the probability that the particles will move downwards.

[0090] Therefore, the particles would originally accelerate towards the high-voltage conductor. After the magnetic field is applied, the particles can only move in an approximately semi-circular horizontal direction close to the electrode surface and gradually fly towards the trap 100.

[0091] b) Multiple exercises

[0092] like Figure 8 and Figure 9 As shown, the metal particles start from the outer shell, have a negative polarity, and move upward. Because the acceleration of the particles moving upward is very small, and the Lorentz magnetic force perpendicular to the direction of the particles' movement and away from the insulator is constantly increasing, the upward velocity component of the particles decreases to 0 during the upward movement, and the particles begin to move downward due to gravity.

[0093] If the particle velocity is appropriate at this time, it will stop in the particle trap zone as mentioned above;

[0094] If the particle speed is low at this time, the metal particle falls into the original insulator region a, collides with the outer shell and jumps up. Due to the Lorentz magnetic force, the metal particle moves away from the insulator again until it falls completely into the trap.

[0095] If the particle velocity is high at this time, the metal particle passes through the metal particle trap (non-region a) and collides with the outer shell in region a of another insulator. Due to the Lorentz force, the metal particle moves away from the insulator again until it falls completely into the trap.

[0096] The metal particle capture system for AC gas-insulated power transmission pipelines proposed in this application, based on an introducer, achieves directional movement of particles through an external magnetic field. This allows the particles to move in an approximately semi-circular horizontal direction close to the electrode surface and ultimately be captured by the trap, thereby suppressing the particle's take-off height, preventing particles from contacting the high-voltage conductor, and improving the operational stability of the gas-insulated transmission line (GIL) and the particle capture efficiency. This solves the technical problems in related technologies where the difficulty in controlling the trajectory of metal particles increases the possibility of flashover in the GIL, and the particle trap has poor particle capture efficiency.

[0097] Next, with reference to the accompanying drawings, a method for capturing metal particles in an AC gas-insulated power transmission pipeline according to an embodiment of this application is described.

[0098] Figure 11 This is a schematic flowchart of a method for capturing metal particles in an AC gas-insulated power transmission pipeline according to an embodiment of this application.

[0099] like Figure 11 As shown, the method for capturing metal particles in an AC gas-insulated power transmission pipeline includes the following steps:

[0100] In step S1101: Detect whether the metal particles are moving.

[0101] In step S1102: when the movement of metal particles is detected, a preset magnetic field with a single direction is introduced. The magnetic field induces the metal particles to move away from the basin insulator, so that the metal particles in the AC gas-insulated power transmission pipeline fall into multiple traps.

[0102] Optionally, in one embodiment of this application, before introducing a preset unidirectional magnetic field, the method further includes: setting the direction of the magnetic field to correspond to the movement direction of the metal particles in the corresponding region, and setting the intensity of the magnetic field to correspond to the velocity of the metal particles.

[0103] Optionally, in one embodiment of this application, before introducing a pre-defined unidirectional magnetic field, the method further includes: setting each of the plurality of traps at the middle position of each section of the DC gas-insulated transmission pipeline to trap metal particles at the middle position of two insulators using a particle trap.

[0104] It should be noted that the foregoing explanation of the embodiment of the metal particle capture system for AC gas insulated power transmission pipelines also applies to the metal particle capture method for AC gas insulated power transmission pipelines in this embodiment, and will not be repeated here.

[0105] The metal particle capture method for AC gas-insulated transmission pipelines proposed in this application can achieve directional movement of particles by using an external magnetic field based on an introducer. This allows the particles to move in an approximately semi-circular horizontal direction close to the electrode surface and ultimately be captured by the trap, thereby suppressing the particle's take-off height, preventing particles from contacting the high-voltage conductor, and improving the operational stability of the GIL and the particle capture efficiency. This solves the technical problems in related technologies where the movement trajectory of metal particles is difficult to control, increasing the possibility of flashover in the GIL, and the particle trap has poor particle capture efficiency.

[0107] The memory 1201, the processor 1202, and the computer program stored on the memory 1201 and executable on the processor 1202.

[0113] If the memory 1201, processor 1202, and communication interface 1203 are implemented independently, then the communication interface 1203, memory 1201, and processor 1202 can be interconnected via a bus to complete communication between them. The bus can be an Industry Standard Architecture (ISA) bus, a Peripheral Component Interconnect (PCI) bus, or an Extended Industry Standard Architecture (EISA) bus, etc. The bus can be divided into address bus, data bus, control bus, etc. For ease of representation, Figure 12 The bus is represented by a single thick line, but this does not mean that there is only one bus or one type of bus.
