Description

Technical Field

[0001] The invention relates to the technical field of porcelain insulators, and in particular to a porcelain insulator with anti-aging performance and a preparation method thereof. Background Art

[0002] In modern power transmission systems, porcelain insulators are key components that connect conductors to supporting structures. Their long-term stability and reliability are directly related to the safe operation of the entire power grid and the power transmission efficiency.

[0003] The design of traditional porcelain insulators, although excellent in electrical insulation performance, has certain limitations in supporting the stability of the conductor. Especially under severe weather conditions, such as strong winds, rain, snow, freezing, etc., the conductor may be subjected to large lateral forces, causing the conductor to slide or swing on the porcelain insulator, which in turn affects the continuity and stability of power transmission. In addition, during long-term operation, due to factors such as mechanical wear and environmental corrosion, the fixing parts between the porcelain insulator and the conductor may become loose, further exacerbating the risk of conductor instability. At the same time, there are also problems such as heavy weight and long batch installation time, which leads to great construction difficulties and affects the progress of porcelain insulator construction and use. Summary of the invention

[0004] The purpose of the present invention is to provide a porcelain insulator with anti-aging performance and a preparation method thereof, so as to solve the technical problem that the existing conductor may be subjected to a large lateral force, causing the conductor to slide or swing on the porcelain insulator, thereby affecting the continuity and stability of power transmission.

[0005] The technical solution of the present invention is achieved in this way:

[0006] The first aspect of the present invention provides a porcelain insulator with anti-aging performance, comprising a porcelain part and a clamping assembly provided on the top of the porcelain part, and a fastening head provided on the bottom of the porcelain part;

[0007] The clamping assembly includes a first groove, and the first groove is slidably connected with mutually symmetrical gravity supporting blocks. The side of the gravity supporting block is connected to the inside of the porcelain part through an elastic part. A rotating rod is rotationally symmetrically arranged at the top of the porcelain part, and a swing rod is rotatably arranged inside the porcelain part. Gears are connected between the gravity supporting blocks, and fixed rods are arranged on both sides of the gears. The end of the fixed rod penetrates into the gravity supporting block, and a cam is arranged at one end of the fixed rod inside the gravity supporting block.

[0008] A further technical solution is that a second groove and a third groove adapted to the swing of the rotating rod are provided on the top of the porcelain piece, and the second groove and the third groove are connected to one end of the rotating rod through a supporting rod.

[0009] A further technical solution is that the porcelain component includes the following basic raw materials by weight: 17-30 parts of silica, 22-30 parts of feldspar, 17-24 parts of clay, 12-18 parts of corundum phase, 12-18 parts of microcrystalline glass, 15-20 parts of nano alumina, 10-14 parts of lightweight filler, 12-19 parts of reinforcing fiber, and 18-28 parts of hydrophobic material.

[0010] A further technical solution is that the microcrystalline glass includes basic components: 10-30 parts of silicon dioxide, 10-28 parts of aluminum oxide, 15-28 parts of boron oxide, 20-30 parts of sodium oxide, and 22-32 parts of titanium oxide.

[0011] A further technical solution is that the reinforcing fiber includes one or a combination of metal fiber, polypropylene fiber, boron fiber, carbon fiber, and aramid fiber.

[0012] A further technical solution is that the hydrophobic material is nano-silicon dioxide.

[0013] A further technical solution is that the lightweight filler is one of foam glass, fumed silica, and porous ceramic particles.

[0014] A further technical solution is that the method for preparing the porcelain piece comprises:

[0015] S1. Preparation of glass-ceramics: grinding silicon dioxide, aluminum oxide, boron oxide, sodium oxide, and titanium oxide to obtain grinding raw materials, heating and melting the grinding raw materials to obtain a glass solution, quenching the obtained glass solution with water, screening, washing, and drying to obtain glass-ceramics for later use;

[0016] S2. Preparation of basic raw materials: Mix silica, feldspar, clay, corundum phase, the microcrystalline glass, nano-alumina, and lightweight filler according to weight, and ball-mill for 14 hours to obtain a slurry;

[0017] S3, preparation of reinforcing fiber solution: using a formic acid solution with a concentration of 30% and reinforcing fibers to prepare a reinforcing fiber solution;

[0018] S4, stirring and mixing the slurry in S2 and the reinforcing fiber solution in S3 to obtain a reinforcing slurry, filtering and dehydrating to obtain a mud cake, leaving it to stand for 18-20 hours to obtain a blank, pressing and drying to obtain an initial model of a porcelain insulator body;

[0019] S5. Apply the hydrophobic material on the surface of the initial model of the main body, dry it at room temperature, cut it, level it, grind it, glue it, and maintain it to obtain a lightweight, high-strength, anti-aging porcelain insulator.

[0020] A further technical solution is that in S1, the heating melting temperature is 1000°C-1500°C.

[0021] The beneficial effects of the present invention are:

[0022] The present invention is installed on the pole tower by fastening the head porcelain part. After the installation is stable, the conductor is placed in the first groove, and the gravity bearing block is pressed downward by the conductor's own gravity, so that the gravity bearing block slides at the top of the porcelain part. At the same time, the gears between the gravity bearing blocks also move downward. When the bottom surface of the gravity bearing block contacts and swings, one end of the swing rod is downward, and the other end will touch the rotating rod using the lever principle. The rotating rod also uses the lever principle, and it moves relatively outside the top surface of the porcelain part to stably clamp the conductor to prevent the conductor from accidentally slipping out of the first groove and causing the risk of leakage. In addition, when the conductor (not charged) is taken out, the conductor does not contact the gravity bearing block, and the pressure on the gravity bearing block is released. Under the action of the elastic member, the gravity bearing block moves vertically upward, and the rotating rod swings to the relative outside to facilitate the removal of the conductor.

[0023] The silica, feldspar, clay, and corundum phases of the present invention have high mechanical strength, high heat resistance, and excellent electrical insulation properties, and can improve the performance of porcelain insulators. The use of microcrystalline glass has good thermal shock resistance, chemical corrosion resistance, and dimensional stability, which helps to improve the anti-aging ability of porcelain insulators. Nano-alumina effectively improves the mechanical strength, wear resistance, and anti-aging properties of the material, while also improving the microstructure of the basic raw materials, improving its toughness and resistance to crack propagation. Lightweight fillers can effectively reduce the overall density of porcelain insulators while reducing the impact on mechanical strength and insulation properties. The mechanical strength and toughness of porcelain insulators are then improved by reinforcing fibers, thereby extending their service life and improving operational reliability. The use of hydrophobic materials can enhance the anti-pollution flashover and self-cleaning capabilities of porcelain insulators, further improving anti-aging properties.

[0028] In order to better understand the technical content of the present invention, specific embodiments are provided below, and the present invention is further described in conjunction with the accompanying drawings.

[0029] Unless otherwise specified, the materials, reagents, etc. used in the embodiments of the present invention can be obtained from commercial sources.

[0030] Example 1

[0031] See also Figure 1-Figure 3 The present invention provides a porcelain insulator with anti-aging performance, which is characterized by comprising a porcelain part 1 and a clamping assembly provided on the top of the porcelain part 1, and a fastening head 2 is provided at the bottom of the porcelain part 1;

[0032] The invention comprises the following basic raw materials by weight: 17 parts of silica, 22 parts of feldspar, 17 parts of clay, 12 parts of corundum phase, 12 parts of microcrystalline glass, 15 parts of nano-alumina, 10 parts of lightweight filler, 12 parts of reinforcing fiber and 18 parts of hydrophobic material.

[0033] The clamping assembly includes a first groove 3, which is slidably connected to a symmetrical gravity bearing block 4. The side of the gravity bearing block 4 is connected to the inside of the porcelain piece 1 through an elastic piece 11. A rotating rod 7 is symmetrically arranged at the top of the porcelain piece 1. A swing rod 5 is rotatably arranged inside the porcelain piece 1. Gears 6 are connected between the gravity bearing blocks 4. Fixed rods 12 are arranged on both sides of the gear 6. The ends of the fixed rods 12 are inserted into the gravity bearing block 4, and a cam 8 is arranged at one end of the fixed rod 12 in the gravity bearing block 4; a second groove 9 and a third groove 10 adapted to the swing of the rotating rod 7 are arranged on the top of the porcelain piece 1, and the second groove 9 and the third groove 10 are connected to one end of the rotating rod 7 through a support rod 13.

[0034] It should be understood that zirconium oxide is also included for the flashover resistance at high voltage points. The fastening head 2 is a threaded head, and the threaded fastening head 2 can be connected by a nut and stably installed on the tower.

[0035] Exemplarily, the porcelain part 1 is installed on the pole tower through the fastening head 2. After the installation is stable, the conductor is placed in the first groove 3. The gravity bearing block 4 is pressed downward by the conductor's own gravity, so that the gravity bearing block 4 slides at the top of the porcelain part 1. At the same time, the gear 6 between the gravity bearing blocks 4 also moves downward. When the bottom surface of the gravity bearing block 4 contacts and swings, one end of the swing rod 5 is downward, and the other end will touch the rotating rod using the lever principle. The rotating rod 7 also uses the lever principle. It moves relatively outside the top surface of the porcelain part 1 to stably clamp the conductor to prevent the conductor from accidentally slipping out of the first groove 3 and causing the risk of leakage. In addition, when the conductor (not charged) is taken out, the conductor does not contact the gravity bearing block 4, and the pressure on the gravity bearing block 4 is released. Under the action of the elastic member 11, the gravity bearing block 4 moves vertically upward, and the rotating rod 7 swings to the relative outside to facilitate the removal of the conductor.

[0036] It should be noted that the elastic member 11 is Figure 3As shown, the elastic member 11 is a spring, the top end of which is connected to the top wall of the porcelain piece, and the other end is connected to the gravity receiving block 4 through a right angle rod. When the wire leaves the first groove 3, the gravity receiving block 4 moves upward through the elastic member 11, so as to facilitate the next re-receiving of the wire.

[0037] It is worth noting that the rotating rod 7 swings toward the second groove 9 and the third groove 10 on the outer side of the top surface of the porcelain piece 1. The second groove 9 and the third groove 10 are adapted to receive the rotating rod to prevent the rotating rod 7 from being blocked by the top surface of the porcelain piece 1 and unable to swing outward.

[0038] In one example, when encountering strong winds, the wire swings with a large amplitude, thereby generating a large forward or backward friction force in the first groove 3. Under the action of the friction force, the driving gear 6 rotates, driving the fixed rod 12 to rotate the cam 8. When the cam 8 rotates to the maximum value, it is clamped with the side wall of the gravity bearing block 4 through the fixed rod 7. In the vertical state, the cam 8 further swings the swing rod 5 mechanically downward, so that the swing rod 5 drives the rotating rod 7 to clamp the wire more strongly, thereby improving the stability of the wire in the first groove 3 and avoiding the situation where the wire accidentally slips out of the first groove 3 when the wind is strong, increasing the safety hazard. In addition, the second groove 9 and the third groove 10 are made of rubber material and have the characteristics of arc elasticity, such as Figure 2 As shown, when the rotating rod 7 is swung upward by the swing lever 5, the driving support rod 13 applies force upward to the second groove 9 and the third groove 10, and the second groove 9 and the third groove 10 are raised to prevent water accumulation in rainy weather. When the wire is detached, the rotating rod 7 swings toward the second groove 9 and the third groove 10, and the swing rod 5 pulls the second groove 9 and the third groove down through the support rod 13, forming grooves that adapt to the swing of the rotating rod 7 to prevent dryness.

[0039] It is worth noting that the clamping assembly of the present invention (except the second groove 9 and the third groove 10) is made of carbon fiber composite material, which has the effects of high strength and light weight.

[0064] Comparative Example 1

[0065] The lightweight filler in the formula is replaced with the same amount of feldspar, and other raw materials are increased in proportion. The rest is the same as Example 3.

[0066] Comparative Example 2

[0067] The reinforcing fiber in the formula was removed, and other raw materials were increased in proportion, and the rest was the same as in Example 3.

[0068] Comparative Example 3

[0069] Compared with Example 3, this comparative example does not use hydrophobic material to coat the initial model of the porcelain insulator body.

[0070] Comparative Example 4

[0071] The nano-alumina in the formula is removed, and other raw materials are increased in proportion. The rest is the same as in Example 3.

[0072] The porcelain insulators prepared in Examples 3 to 5 and Comparative Examples 1 to 4 were tested, and the results were as follows:

[0073] Experiment 1: Weigh the sample and place it in -30-50℃ environment for 3 days to observe whether the sample has cracks;

[0074] Experiment 2: After the sample was subjected to a 100-hour corona aging test, the hydrophobic contact angle was measured using a contact angle tester. The corona aging test conditions were: the sample was subjected to a 100-hour corona aging test at 3.5 kV;

[0078] Table 1 Performance test values ​​of ceramic insulators of Examples 3-5 and Comparative Examples 1-4;

[0079]

[0080]

[0081] As can be seen from Table 1, the insulators made using the raw materials and methods of the present invention are lightweight, high-strength, anti-aging porcelain insulators. The lightweight porcelain insulators have high bearing capacity and good hydrophobicity, and Example 3 has the best effect. The samples of Examples 3 to 5 were placed in an environment of -30-50°C for 3 days for testing, and the surface was smooth and flat without cracks. In Comparative Example 2, a small number of cracks appeared on the surface of the porcelain insulator after the reinforcing fiber was removed, indicating that the reinforcing fiber contributed greatly to the insulator's resistance to large changes in environmental temperature differences. The artificial simulation of contamination accumulation experiments showed that Examples 3 to 5 had excellent contamination resistance and almost no dust on the surface. The hydrophobic material (Comparative Example 3) and nano-alumina (Comparative Example 4) were not pre-treated, and the obtained porcelain insulator surface dust was more serious, indicating that the present invention uses hydrophobic materials and nano-alumina to significantly improve the contamination resistance of porcelain insulators. The hydrophobic contact angle experiment shows that nano-alumina and hydrophobic materials have a significant effect on the water resistance of porcelain insulators. The water contact angles drop to 109°, 98°, and 80° respectively. The porcelain insulators treated with nano-alumina and hydrophobic materials can form a surface with excellent hydrophobic properties, effectively reducing the accumulation of dirt on the surface of the porcelain insulators and improving the anti-flashover and ice flashover performance. The tensile strength test shows that the reinforcing fiber and nano-alumina in the formula help the porcelain insulator to improve the mechanical strength, wear resistance and anti-aging performance of the material, and at the same time improve the microstructure of the basic raw material, improve its toughness and crack propagation resistance, and also improve the mechanical strength and toughness, thereby extending its service life and improving operational reliability. The tensile strength of Examples 3 to 5 is between 237 and 239; the tensile strength of the porcelain insulators with the removal of reinforcing fiber (Comparative Example 2), nano-alumina (Comparative Example 4), reinforcing mud, and hydrophobic material (Comparative Example 3) in the insulator formula is reduced to 210MPa, 198MPa, and 178MPa respectively. The interaction between the raw materials is stronger, which is more conducive to the formation of porcelain insulators with excellent mechanical properties. The light weight strength test shows that Examples 3 to 5 also produce excellent mechanical properties, and compared with Comparative Example 1, the porcelain insulator still maintains high strength and anti-aging, high bearing capacity and good hydrophobicity, and excellent mechanical properties under the condition of overall weight reduction.

[0082] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
