Description

Technical Field

[0001] This utility model relates to the technical field of insulators, specifically to a tensile insulator. Background Technology

[0002] Insulators are one of the most important components in a power system. Their function is to isolate power lines and towers, prevent power lines from grounding, and thus ensure the normal operation of the power system. The tensile strength of insulators is one of their key performance characteristics, which directly affects the durability and safety of insulators. Therefore, testing the tensile strength of insulators is essential to ensure the safe and stable operation of the power system.

[0003] During long-distance transportation and long-term use, mechanical and electrical equipment may experience varying degrees of tension between the current-carrying conductor and the insulator due to vibration and other reasons. Many insulator inserts have unreasonable structures and are often bonded to the insulator with adhesives. Under long-term tension, the inserts may fall off, which will adversely affect the structural stability of the mechanical and electrical equipment. Summary of the Invention

[0004] The purpose of this invention is to provide a tensile insulator to solve the above-mentioned defects caused by the prior art.

[0005] A tensile insulator includes a ceramic skirt and an alloy suspension. A metal main rod is internally connected to the ceramic skirt. A positioning mechanism is provided at the other end of the metal main rod. The positioning mechanism connects the other end of the metal main rod through multiple sets of alloy suspensions internally, facilitating the docking of multiple sets of ceramic skirts. A tensile mechanism is provided on the other side of the alloy suspension. The tensile mechanism reduces the tensile force caused by vibration during operation of the alloy suspension and ceramic skirt according to usage requirements, ensuring that multiple sets of ceramic skirts are decompressed.

[0006] Preferably, the tensile mechanism includes a tensile base, a guide plate, a buffer rod, a rubber sleeve, a hanging ring, a guide groove, and a return spring post. The buffer rod is connected through one side of the tensile base, and the outer side of the buffer rod is wrapped with a rubber sleeve. The tensile base is connected to one side of the rubber sleeve, and the hanging ring is connected to the top of the buffer rod. The outer side of the tensile base is provided with a guide groove, and the outer side of the guide groove is connected to a guide plate. One end of the return spring post is welded to both sides of the guide plate, and the other end of the return spring post is connected to the guide groove.

[0007] Preferably, the guide groove is connected to both sides of the guide plate via an internally provided reset spring post.

[0008] Preferably, the positioning mechanism includes a metal main rod, a positioning box, a guide rod, a U-bolt, an internal thread seat, and an alloy suspension seat. The metal main rod is evenly spaced below the positioning box, and guide rods are symmetrically arranged on the other side of the positioning box. The other end of the metal main rod is connected to a U-bolt, and an internal thread seat is bolted inside the positioning box. An alloy suspension seat is connected to a bearing directly below the internal thread seat.

[0009] Preferably, the positioning box is connected to one end of the metal main rod by an internal alloy suspension seat.

[0010] Preferably, the alloy suspension is connected to the inside of the positioning box via an internally threaded seat at its top.

[0011] Compared with the prior art, the present invention has the following advantages:

[0012] 1. The guide plate is guided on both sides by symmetrically arranged guide grooves, and the pullable range of the guide plate is controlled by the return spring columns of different diameters. The force is reduced during the pulling process of the insulator. The connection method is optimized so that no torque is generated on the main body of the insulation, thus improving the tensile performance. The guide plate is guided on both sides by symmetrically arranged guide grooves to avoid the return spring columns causing the guide plate to tilt or deviate during the pulling process.

[0013] 2. The positioning box is connected to one end of the metal main rod by alloy suspensions of different sizes set inside. The entire insulator is set with a detachable and assembleable structure to adapt to the needs of different voltage levels, which is highly flexible in use. At the same time, the installation components and pre-installed hooks facilitate the rapid installation of insulators, saving time and effort, and making it convenient for the erection of insulators in outdoor environments.

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figures 1 to 5 As shown, a tensile insulator includes a ceramic skirt 1 and an alloy suspension seat 16. A metal main rod 9 is internally connected to the ceramic skirt 1. A positioning mechanism 8 is provided at the other end of the metal main rod 9. The positioning mechanism 8 connects to the other end of the metal main rod 9 through multiple sets of alloy suspension seats 16 internally, facilitating the docking of multiple sets of ceramic skirts 1. A tensile mechanism 7 is provided on the other side of the alloy suspension seat 16. The tensile mechanism 7 reduces the tensile force caused by vibration during operation of the alloy suspension seat 16 and the ceramic skirt 1 according to the usage requirements, ensuring that the multiple sets of ceramic skirts 1 are decompressed.

[0023] In this embodiment, the tensile mechanism 7 includes a tensile base 2, a guide plate 3, a buffer rod 4, a rubber sleeve 5, a hanging ring 6, a guide groove 13, and a return spring post 14. The buffer rod 4 is connected through one side of the tensile base 2. The rubber sleeve 5 is wrapped around the outside of the buffer rod 4. The tensile base 2 is connected to one side of the rubber sleeve 5. The hanging ring 6 is connected to the top of the buffer rod 4. The guide groove 13 is provided on the outer side of the tensile base 2. The guide plate 3 is connected to the outer side of the guide groove 13. One end of the return spring post 14 is welded to both sides of the guide plate 3. The other end of the return spring post 14 is connected to the guide groove 13.

[0024] In this embodiment, the guide groove 13 is connected to both sides of the guide plate 3 through the internally provided reset spring post 14. The reset spring post 14 pulls on both sides of the guide plate 3 to buffer the pulling force.

[0025] In this embodiment, the positioning mechanism 8 includes a metal main rod 9, a positioning box 10, a guide rod 11, a U-bolt 12, an internal thread seat 15, and an alloy suspension seat 16. The metal main rods 9 are evenly spaced below the positioning box 10. The guide rods 11 are symmetrically arranged on the other side of the positioning box 10. The other end of the metal main rod 9 is connected to the U-bolt 12. The internal thread seat 15 is bolted inside the positioning box 10. The alloy suspension seat 16 is connected to the bearing directly below the internal thread seat 15. The wires are locked and connected by the U-bolt 12, and the multiple sets of insulators are further buffered.

[0026] In this embodiment, the positioning box 10 is engaged with one end of the metal main rod 9 via an internal alloy suspension 16, and the metal main rod 9 is connected to the bottom end of the alloy suspension 16, thereby improving the stability of the connection of the metal main rod 9.

[0027] In this embodiment, the alloy suspension 16 is connected to the inside of the positioning box 10 through the internal thread seat 15 provided at the top. The contact between the alloy suspension 16 and the internal thread seat 15 improves the convenience of disassembling and replacing the alloy suspension 16.

[0028] In practical applications, this type of tensile insulator includes the following tasks:

[0029] Step 1: During use, the hanging ring 6 on one side of the buffer rod 4 is fixed to the frame of the electrical equipment. According to the buffering requirements, the reset spring column 14 is installed on both sides of the guide groove 13, so that the top of the reset spring column 14 is welded to both sides of the guide plate 3, thereby guiding and positioning both sides of the guide plate 3. When a pull occurs, the hanging ring 6 will drive the buffer rod 4 to pull, and the rubber sleeve 5 will increase the friction of the buffer rod 4 during the pulling process, so as to avoid hard contact between the buffer rod 4 and the tensile seat 2.

[0030] Step 2: During use, according to the diameter of the ceramic skirt 1, the internal thread seat 15 set at the top of the alloy suspension seat 16 is fitted with the inside of the positioning box 10. The internal thread seat 15 and the positioning box 10 are locked with bolts. Then, the alloy suspension seat 16 set at the bottom of the internal thread seat 15 is engaged with the bottom of the metal main rod 9. Finally, the U-bolt 12 on the other side of the metal main rod 9 is connected and locked with the wire.

[0031] Step 3: The operator inserts the guide rod 11, which is located at the bottom of the tensile support 2, through the outside of the tensile support 2, so that the bottom end of the guide rod 11 is connected to one side of the positioning box 10. The positioning box 10 and the guide rod 11 are locked together with bolts. When the buffer rod 4 is pulled, the guide rod 11 will extend and retract accordingly with the guide plate 3, thereby buffering the pulling force generated by the multiple ceramic skirts 1 and the metal main rod 9.

[0032] Therefore, the above-disclosed embodiments are merely illustrative in all respects and are not the only ones. All modifications within the scope of this utility model or its equivalents are included in this utility model.
