Description

Technical Field

[0001] The present application relates to the technical field of operation and control of power equipment, and particularly relates to a method, device, equipment and readable storage medium for improving the insulation strength of electrical equipment. Background Art

[0002] In the actual application process, the insulation system of electrical equipment is very important for the safety of electrical equipment. For example, the insulation system of gas-insulated switchgear is very important. Gas-insulated switchgear is a composite insulation system composed of gas and solid. Gas-insulated switchgear includes high-voltage conductors, aluminum alloy enclosures, insulators, and insulating gases. Among them, the pot-type insulator is a conical insulator. The pot-type insulator can not only support the conductor but also play a role in isolating the gas chamber, and is the key to the insulation system of the entire gas-insulated switchgear. On the one hand, the interfacial charge accumulation of gas-solid can lead to an increase in the electrical stress on the surface of the insulator. Under the action of complex electrical stress, significant charge accumulation will appear on the surface of the insulator. When the high-voltage conductor carries current and forms a temperature gradient field in the pipeline, due to the large influence of temperature on the conductivity of the insulator, both the tangential field strength and the normal field strength will show different changes, which is likely to exacerbate the charge accumulation on the surface of the insulator. On the other hand, the long-term coupling action of electro-thermal-mechanical stress is likely to cause changes in the physical and chemical properties on the surface of the insulator. The aging of the body material or surface material of the insulator or the erosion by the decomposition products of SF6 gas will cause changes in microscopic characteristics and lead to deterioration of electrical performance. The interaction of these two factors will more easily lead to insulator interface insulation failure and serious ablation faults.

[0003] The existing surface treatment technology for insulators focuses on the regulation of the surface insulation strength and surface charge accumulation of insulators by the interface coating, while paying little attention to the complex interface problems introduced by the coating; at the same time, the optimal design of the geometric structure of the pot-type insulator is not fully integrated with the surface treatment technology.

[0055] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present application.

[0056] In view of the fact that most of the current solutions for improving the insulation strength of electrical equipment are difficult to adapt to complex and changeable business requirements, for this reason, the applicant has studied an electrical equipment insulation strength solution. This electrical equipment insulation strength solution can be based on the insulation strength of the pot-type insulator optimized by geometric structure and the coating problem of the surface charge of the pot-type insulator, form a design method of the pot-type insulator that meets the interface gradient insulation requirements, and formulate relevant strategies for the green electrical equipment environmental protection gas operation and maintenance facing gas decomposition and gas leakage faults based on this method. Further, the interface insulation gas-solid compatibility analysis and comprehensive performance evaluation of the pot-type insulator are carried out, and finally a pot-type insulator that meets the insulation requirements of electrical equipment is formed, which is of great significance for improving the insulation reliability and operation stability of pipeline transmission technology.

[0057] The method provided by the embodiments of the present application can be used in many general or special computing device environments or configurations. For example: personal computers, server computers, handheld devices or portable devices, tablet-type devices, multi-processor devices, distributed computing environments including any of the above devices or equipment, and so on.

[0058] An embodiment of the present application provides a method for improving the insulation strength of electrical equipment. This method can be applied to various power systems or power equipment management systems, and can also be applied to various computer terminals or intelligent terminals. The execution subject can be the processor or server of a computer terminal or an intelligent terminal.

[0059] The following combines Figure 1 to introduce the process of the method for improving the insulation strength of electrical equipment given in the embodiment of the present application. As Figure 1 shown, this process can include the following steps:

[0060] Step S101: Construct an epoxy resin cross-linking system model and a nano-doping modification system model according to the parameters of the body material and surface material of the insulator of the target electrical equipment.

[0061] Specifically, in the actual application process, an insulator is a device that can withstand voltage and mechanical stress and is installed between conductors at different potentials or between a conductor and a grounding member. There are many types of insulators with various shapes. Although the structures and shapes of different types of insulators vary greatly, they are all composed of two major parts: insulating parts and connecting fittings.

[0062] An insulator is a special insulating control device that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on telegraph poles, and gradually developed to have many disc-shaped insulators hanging at one end of a high-type high-voltage wire connection tower, which is to increase the creepage distance and is usually made of glass or ceramic.

[0063] According to different installation methods, insulators can be divided into suspension insulators and post insulators; according to different insulating materials used, they can be divided into porcelain insulators, glass insulators, and composite insulators. Among them, composite insulators are also called synthetic insulators; according to different voltage levels used, they can be divided into low-voltage insulators and high-voltage insulators; according to different environmental conditions of use, pollution-resistant insulators for use in polluted areas are derived; according to different types of applied voltages, DC insulators are derived; there are also various special-purpose insulators, such as insulating cross-arms, semiconductor glaze insulators, and tension insulators, spool insulators, and wiring insulators for distribution. In addition, according to the possibility of breakdown of the insulating part, they can be divided into two categories: type A, that is, non-breakdown insulators, and type B, that is, breakdown insulators.

[0064] Suspension insulators are widely used in the insulation and mechanical fixation of high-voltage overhead transmission lines and flexible busbars in power generation and substation. Among suspension insulators, they can be further divided into disc suspension insulators and rod suspension insulators. Disc suspension insulators are the most widely used type of insulator in transmission lines. Rod suspension insulators have been widely adopted in some countries.

[0065] Post insulators are mainly used for the insulation and mechanical fixation of busbars and electrical equipment in power plants and substations. In addition, post insulators are often used as components of electrical equipment such as disconnectors and circuit breakers. Among post insulators, there are also pin-type post insulators and rod-type post insulators. Pin-type post insulators are mostly used in low-voltage distribution lines and communication lines, while rod-type post insulators are mostly used in high-voltage substations.

[0066] Porcelain insulators Insulators with insulating parts made of electrical porcelain. Electrical porcelain is baked from quartz, feldspar, and clay as raw materials. The porcelain parts of porcelain insulators are usually covered with porcelain glaze to improve their mechanical strength, prevent water infiltration, and increase surface smoothness. Among various insulators, porcelain insulators are the most commonly used.

[0067] Glass insulators Insulators with insulating parts made of tempered glass. Its surface is in a state of compressive prestress. If cracks and electrical breakdown occur, the glass insulator will break into small pieces by itself, commonly known as "self-explosion". This characteristic enables glass insulators not to require "zero-value" detection during operation.

[0068] Composite insulators are also called synthetic insulators. Their insulating parts are insulators composed of glass fiber resin core rods or core tubes and organic material sheaths and umbrella skirts. Their characteristics are small size, light weight, high tensile strength, and excellent anti-fouling flashover performance. However, their anti-aging ability is not as good as that of porcelain and glass insulators.

[0069] Composite insulators include: rod-shaped suspension insulators, insulating cross-arms, post insulators, and hollow insulators. Among them, hollow insulators are also called composite bushings. Composite bushings can replace porcelain bushings used in various electrical equipment, such as transformers, lightning arresters, circuit breakers, capacitive bushings, and cable terminals. Compared with porcelain bushings, in addition to having the advantages of high mechanical strength, light weight, and small dimensional tolerances, they can also avoid damage caused by explosion and fragmentation.

[0070] Low-voltage insulators and high-voltage insulators Low-voltage insulators refer to insulators used in low-voltage distribution lines and communication lines. High-voltage insulators refer to insulators used in high-voltage and extra-high-voltage overhead transmission lines and substations. To meet the needs of different voltage levels, insulator strings or multi-section insulating posts are usually composed of different numbers of the same type of single insulators.

[0071] Pollution-resistant insulators mainly take measures such as increasing or enlarging the insulator umbrella skirts or ribs to increase the creepage distance of the insulators, so as to improve the electrical strength of the insulators under polluted conditions. At the same time, measures are also taken to change the structure shape of the umbrella skirts to reduce the natural pollution accumulation on the surface, so as to improve the anti-fouling flashover performance of the insulators. The creepage distance ratio of pollution-resistant insulators is generally 20% - 30% higher than that of ordinary insulators, or even more. In some areas with frequent pollution flashovers in the national power grid, pollution-resistant insulators with a double-layer umbrella structure shape are commonly used. Such insulators have strong self-cleaning ability and are easy to be manually cleaned.

[0072] DC insulators mainly refer to disc insulators used in DC power transmission. DC insulators generally have a longer creepage distance than AC pollution-resistant insulators. Their insulating parts have a higher volume resistivity, not less than 10 Ω·m at 50 °C. Sacrificial electrodes for anti-electrolytic corrosion, such as zinc sleeves and zinc rings, should be installed on their connecting fittings.

[0073] Type A insulators are non-breakdown insulators. Among them, for cast resin insulators, the dry flashover distance is not greater than 3 times the breakdown distance.

[0074] Type B insulators are breakdown insulators. For cast resin insulators, the breakdown distance is less than 1 / 3 of the dry flashover distance. The dry flashover distance of an insulator refers to the shortest distance through the air along the outer surface of the insulating part; the breakdown distance refers to the shortest distance through the insulating material of the insulating part.

[0075] The main functions of insulators are to achieve electrical insulation and mechanical fixation. Therefore, various requirements for electrical and mechanical properties are specified. For example, under the action of specified operating voltage, lightning overvoltage, and internal overvoltage, there is no breakdown or surface flashover; under the action of specified long-term and short-term mechanical loads, there is no damage or destruction; after long-term operation under specified mechanical, electrical loads, and various environmental conditions, there is no obvious deterioration; for the fittings of insulators, there is no obvious corona discharge phenomenon under operating voltage to avoid interfering with the reception of radio or TV. Since insulators are widely used devices, interchangeability is also required for their connecting fittings. In addition, according to different models and usage conditions, the technical standards of insulators also require various electrical, mechanical, physical, and environmental condition change tests on insulators to test their performance and quality.

[0076] Due to the needs of practical applications, the emergence of insulators is to find an insulating control component that will not fail due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions. If an insulator fails due to various mechanical and electrical stresses caused by changes in environmental and electrical load conditions, then the insulator will not play a significant role and will damage the service life and operation of the entire line.

[0077] In the process of practical application, the insulators of some electrical equipment use gas as the main insulating medium.

[0078] For example, gas-insulated switchgear (GIS) and gas-insulated pipe transmission lines use gas as the main insulating medium, and use support insulators to mechanically fix the conductors and insulate them from the outer shell.

[0079] It has been found through research that most faults of electrical equipment originate from the flashover on the surface of insulators. In most cases, insulators become the weakest link and decisive factor in the overall insulation of the power system.

[0080] It is found that a large amount of charge can accumulate on the surface of the insulator under the action of an externally applied voltage, and the charge accumulation on the insulation surface will affect the surface discharge of the insulation.

[0081] There are various ways for charge accumulation to occur on the insulator surface. Three common ways can include the conduction current in the insulator body, the gas current density, and the surface conduction current.

[0082] Among them,

[0083] The surface conduction current of the insulator can be expressed by the following formula:

[0084] J s =k S *E τ (1)

[0085] J s can represent the surface conduction current of the insulator;

[0086] k S can represent the surface conductivity of the insulating material;

[0087] E τ can represent the tangential component of the electric field at the solid-gas interface.

[0088] According to the current continuity equation, the transient equation for the charge accumulation on the insulator surface can be expressed as:

[0089]

[0090] Among them;

[0091] σ can represent the surface charge density of the insulator;

[0092] t can represent the charge accumulation time;

[0093] n can represent the unit normal component of the insulator pointing to the gas side.

[0094] Among them, the conduction current in the insulator body includes two parts: the displacement current and the conduction current, that is:

[0095]

[0096] In the formula,

[0097] J V can represent the conduction current in the insulator body

[0098] D can represent the electric displacement vector of the insulator;

[0099] k S can represent the conductivity of the solid dielectric body;

[0100] E d can represent the electric field strength inside the medium.

[0101] The gas current density of the insulator can be expressed as:

[0102]

[0103] Among them,

[0104] J G can represent the gas current density of the insulator;

[0105] n + and n - can respectively represent the concentrations of positive and negative ions;

[0106] μ + and μ - can respectively represent the mobilities of positive and negative ions;

[0107] D + and D - are respectively the diffusion coefficients of positive and negative ions;

[0108] e is the unit charge amount.

[0109] It can be seen from this that in the transient equation (2) of the insulator surface charge accumulation, the charge components that describe the conduction of the internal carriers of the insulator with specific surface charge accumulation to the gas-solid interface and the charge components that the carriers in the gas migrate to the interface along the electric field line direction are both closely related to the normal electric field components on the solid side or gas side of the insulator surface. The charge accumulation on the insulator surface is driven by the normal electric field component on the insulator surface, and there are two major conduction paths: gas-side conduction and solid-side conduction; at the same time, the conduction component of the carriers along the insulator surface is the transmission path of the insulator surface charge, and this process is driven by the tangential electric field component on the insulator surface.

[0110] Therefore, in order to better improve the insulation strength of the insulator of the target electrical equipment, a pot-type insulator can be made to be the insulator of the electrical equipment.

[0111] In order to make a pot-type insulator with better insulation strength, an epoxy resin cross-linking system model and a nano-doping modification system model can be constructed according to the parameters of the body material and surface material of the insulator of the target electrical equipment.

[0112] Among them,

[0113] the parameters of the body material and surface material of the insulator of the target electrical equipment can include epoxy resin matrix, Al2O3, and nano-S i C .

[0114] The epoxy resin crosslinking system model and the nano-doping modification system model can reflect the performance of the target pot insulator.

[0115] The epoxy resin crosslinking system model and the nano-doping modification system model can verify whether the performance of the target pot insulator changes before and after the nano-coating is applied.

[0116] For example, the epoxy resin crosslinking system model and the nano-doping modification system model can reflect the data of the surface material of the insulator of the target electrical equipment, including the change in the reflected temperature, the change in the total number of molecules, and the main pyrolysis products.

[0117] Step S102: Construct a microscopic system model of the target pot insulator based on the epoxy resin crosslinking system model and the nano-doping modification system model.

[0118] Specifically, as introduced above, the method provided by the embodiments of the present application can construct the epoxy resin crosslinking system model and the nano-doping modification system model based on the parameters of the body material and the surface material of the insulator of the target electrical equipment.

[0119] Among them, the epoxy resin crosslinking system model and the nano-doping modification system model can reflect the relevant performance of the target pot insulator.

[0120] For example,

[0121] The epoxy resin crosslinking system model and the nano-doping modification system model can reflect the data of the surface material of the insulator of the target electrical equipment, including the change in the reflected temperature, the change in the total number of molecules, and the main pyrolysis products.

[0122] Therefore, after determining the epoxy resin crosslinking system model and the nano-doping modification system model, a microscopic system model of the target pot insulator can be further constructed based on the epoxy resin crosslinking system model and the nano-doping modification system model.

[0123] Among them, the microscopic system model of the target pot insulator can help to more clearly understand the performance and shape of the target pot insulator, and can help to understand the change mechanism of the insulation performance of the target pot insulator from the essence.

[0124] Step S103: Analyze the data of the change in the reflected temperature, the change in the total number of molecules, and the main pyrolysis products of the surface material of the insulator of the target electrical equipment based on the epoxy resin crosslinking system model and the nano-doping modification system model.

[0125] Specifically, as can be seen from the above introduction, the method provided by the embodiments of the present application can construct the epoxy resin cross-linking system model and the nano-doping modification system model according to the parameters of the body material and the surface material of the insulator of the target electrical equipment.

[0126] Among them,

[0127] The epoxy resin cross-linking system model and the nano-doping modification system model can feedback the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment. Therefore, after determining the epoxy resin cross-linking system model and the nano-doping modification system model, the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment can be analyzed according to the epoxy resin cross-linking system model and the nano-doping modification system model.

[0128] Determining the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment can help to determine the relevant materials for manufacturing the target basin insulator according to the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment.

[0129] Step S104, determine the scheme for manufacturing the nano-doping material of the target basin insulator according to the microscopic system model of the target basin insulator, the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment.

[0130] Specifically, as can be seen from the above introduction, the method provided by the embodiments of the present application can determine the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment according to the epoxy resin cross-linking system model and the nano-doping modification system model.

[0131] The materials for manufacturing the target basin insulator are related to the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment.

[0132] Therefore, after determining the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment, the scheme for manufacturing the nano-doping material of the target basin insulator can be determined according to the microscopic system model of the target basin insulator, the reflected temperature change, the change in the total number of molecules, and the data of the main pyrolysis products of the surface material of the insulator of the target electrical equipment.

[0133] So that the pot insulator can be manufactured according to the scheme for manufacturing the nano-doped material of the target pot insulator to meet the insulation strength requirements of the target electrical equipment.

[0134] Step S105: Manufacture the target pot insulator according to the scheme for manufacturing the nano-doped material of the target pot insulator.

[0135] Specifically, as can be seen from the above introduction, the method provided in the embodiment of the present application can determine the scheme for manufacturing the nano-doped material of the target pot insulator.

[0136] The scheme for manufacturing the nano-doped material of the target pot insulator includes the raw materials for manufacturing the nano-doped material of the target pot insulator and the specific manufacturing method.

[0137] The nano-doped material of the target pot insulator can be manufactured according to the scheme for manufacturing the nano-doped material of the target pot insulator.

[0138] Therefore, after determining the scheme for manufacturing the nano-doped material of the target pot insulator, the nano-doped material of the target pot insulator can be manufactured according to the scheme for manufacturing the nano-doped material of the target pot insulator, and then the nano-doped material of the target pot insulator can be used to manufacture the target pot insulator.

[0139] Step S106: Verify whether the insulation strength of the target pot insulator meets the insulation strength requirements of the target electrical equipment.

[0140] Specifically, as can be seen from the above introduction, after determining the scheme for manufacturing the nano-doped material of the target pot insulator, the method provided in the embodiment of the present application can manufacture the nano-doped material of the target pot insulator according to the scheme for manufacturing the nano-doped material of the target pot insulator, and then the nano-doped material of the target pot insulator can be used to manufacture the target pot insulator.

[0141] After manufacturing the target pot insulator, to ensure that the insulation strength of the target pot insulator can meet the insulation strength requirements of the target electrical equipment, it is possible to further verify whether the insulation strength of the target pot insulator meets the insulation strength requirements of the target electrical equipment after manufacturing the target pot insulator.

[0142] If the insulation strength of the target pot insulator meets the insulation strength requirements of the target electrical equipment, it means that the insulation strength of the target pot insulator manufactured according to the scheme for manufacturing the nano-doped material of the target pot insulator can meet the insulation strength requirements of the target electrical equipment, and then step S107 can be executed.

[0143] If the insulation strength of the target pot insulator does not meet the insulation strength requirement of the target electrical equipment, it indicates that the insulation strength of the target pot insulator fabricated according to the scheme for fabricating the nano-doped material of the target pot insulator does not meet the insulation strength requirement of the target electrical equipment. It is necessary to fabricate a new target pot insulator that can meet the insulation strength requirement of the target electrical equipment, and then step S108 can be performed.

[0144] Step S107: Use the target pot insulator as the insulation material of the target electrical equipment.

[0145] Specifically, as can be seen from the above introduction, the method provided in the embodiments of the present application can further verify whether the insulation strength of the target pot insulator meets the insulation strength requirement of the target electrical equipment after fabricating the target pot insulator.

[0146] If the insulation strength of the target pot insulator meets the insulation strength requirement of the target electrical equipment, it indicates that the insulation strength of the target pot insulator fabricated according to the scheme for fabricating the nano-doped material of the target pot insulator can meet the insulation strength requirement of the target electrical equipment. Then, the target pot insulator can be used as the insulation material of the target electrical equipment.

[0147] Using the target pot insulator as the insulation material of the target electrical equipment can effectively improve the insulation strength of the target electrical equipment, which helps to ensure the safety and stability of the electrical equipment in the power system.

[0148] Step S108: Adjust the proportion of the epoxy resin composite material for fabricating the target pot insulator.

[0149] Specifically, as can be seen from the above introduction, the method provided in the embodiments of the present application can further verify whether the insulation strength of the target pot insulator meets the insulation strength requirement of the target electrical equipment after fabricating the target pot insulator.

[0150] If the insulation strength of the target pot insulator does not meet the insulation strength requirement of the target electrical equipment, it indicates that the insulation strength of the target pot insulator fabricated according to the scheme for fabricating the nano-doped material of the target pot insulator does not meet the insulation strength requirement of the target electrical equipment. It is necessary to fabricate a new target pot insulator that can meet the insulation strength requirement of the target electrical equipment, and then try to adjust the proportion of the epoxy resin composite material for fabricating the target pot insulator.

[0151] To produce an epoxy resin composite material for the target pot insulator that can improve the insulation strength of the target electrical equipment, so that a new target pot insulator can be made using the re-produced epoxy resin composite material for the target pot insulator.

[0152] Step S109: Use the adjusted ratio of the epoxy resin composite material for making the target pot insulator as the target ratio of the epoxy resin composite material.

[0153] Specifically, as can be seen from the above introduction, when the insulation strength of the target pot insulator provided by the method in the embodiment of the present application does not meet the insulation strength requirement of the target electrical equipment, the ratio of the epoxy resin composite material for making the target pot insulator can be tried to be adjusted.

[0154] After adjusting the ratio of the epoxy resin composite material for making the target pot insulator, the adjusted ratio of the epoxy resin composite material for making the target pot insulator can be used as the target ratio of the epoxy resin composite material.

[0155] After using the adjusted ratio of the epoxy resin composite material for making the target pot insulator as the target ratio of the epoxy resin composite material, the operation of determining the scheme for making the nano-doped material for the target pot insulator can be returned to and executed until the insulation strength of the produced target pot insulator meets the insulation strength requirement of the target electrical equipment.

[0156] For example,

[0157] In the actual application process, the methods for regulating the tangential and normal electric field intensity gradients of the pot insulator can be used to study the influence laws of the transient or steady-state process of the applied electric stress and the temperature gradient on the charges at the solid-solid interface and gas-solid interface of the pot insulator. By integrating the optimization of the insulator geometric structure and the surface gradient coating technology, a regulation mode of the dielectric gradient, conductivity gradient and tangential field strength of the pot insulator can be established.

[0158] For example,

[0159] Suppose the tangential electric field intensity of a certain pot insulator is Q(x, y), and the normal electric field intensity is F(x, y).

[0160] where x is the abscissa and y is the ordinate;

[0161] At this time, the temperature gradient of the pot insulator is:

[0162] T(x,y) = P(Q(x,y) + F(x,y))

[0163] The temperature gradient threshold of the pot insulator is set to T0;

[0164] If the temperature gradient T(x,y) of the basin insulator is ≥ T0, then the regulation methods of the dielectric gradient, conductivity gradient, and tangential field strength of the basin insulator can be as follows:

[0165] Coat the surface of the basin insulator with a nano-coating material, ensuring that the thickness of the nano-material is not less than 0.3 mm;

[0166] If the temperature gradient T(x,y) of the basin insulator < T0, then it is not necessary to regulate the dielectric gradient, conductivity gradient, and tangential field strength of the basin insulator;

[0167] In addition, the normal electric field treatment method is the same as the tangential electric field.

[0168] Furthermore, the method provided by the embodiments of the present application can also use the free boundary surface mesh parameterization modeling method, with the minimization of the tangential normal field strength on both sides of the insulator as the optimization goal, to carry out the optimization of the surface contour curve parameters and support the realization of the collaborative optimization design of the surface coating and geometric structure of the basin insulator.

[0169] For example, assume that the mesh of the free boundary is n, and the tangential electric field intensity on both sides of the insulator is Q(x,y);

[0170] The tangential field strength threshold on both sides of the insulator is set to Q0;

[0171] If the tangential normal field strength Q(x,y) on both sides of the insulator is greater than or equal to Q0 at this time, then the mesh n increases by a step size of 2, and the convergence condition is that Q(x,y) is less than Q0;

[0172] Among them,

[0173] Q(x,y) = ∑((n - 1) * Q(x + y))

[0174] From the technical solutions introduced above, it can be seen that the method provided by the embodiments of the present application can be based on the insulation strength of the basin insulator optimized by geometric structure and the coating problem of the surface charge of the basin insulator, form a design method of the basin insulator that meets the interface gradient insulation requirements, and formulate relevant strategies for the environmental protection gas operation and maintenance of green electrical equipment facing gas decomposition and gas leakage faults based on this method. Furthermore, carry out the analysis of the interface insulation gas-solid compatibility and comprehensive performance evaluation of the basin insulator, and finally form a basin insulator that meets the insulation requirements of electrical equipment, which is of great significance for improving the insulation reliability and operation stability of pipeline transmission technology.

[0175] As can be seen from the above introduction, the method provided by the embodiments of the present application can manufacture the target basin insulator according to the scheme of manufacturing the nano-doped material of the target basin insulator, including:

[0179] For example, the target ratios of the matrix raw material, particles, and epoxy resin composite material for fabricating the target nano-doped material of the pot insulator can be understood.

[0180] Therefore, after determining the scheme for fabricating the target nano-doped material of the pot insulator, the target ratios of the matrix raw material, particles, and epoxy resin composite material for fabricating the target nano-doped material of the pot insulator can be further determined according to the scheme for fabricating the target nano-doped material of the pot insulator.

[0202] Among them, the second simulation result may include the current signal distribution of the electric field when the target pot insulator is applied to the target electrical equipment.
