Description

Technical Field

[0001] This utility model relates to the field of electrode technology, specifically a multifunctional solid-sealed electrode. Background Technology

[0002] Solid-sealed terminals, also known as solid-sealed vacuum interrupters, are independent components formed by encapsulating the vacuum interrupter and other parts with solid insulating materials using a special process. Currently, epoxy resin is the primary solid insulating encapsulation material used for solid-sealed terminals. Although epoxy resin has advantages such as high insulation, strong sealing, and high structural strength, some problems still exist in practical applications.

[0003] First, epoxy resin has limited temperature resistance. In high-temperature environments, epoxy resin may gradually soften and deform, thus affecting the mechanical and electrical properties of the solidified electrode. The coefficient of thermal expansion of epoxy resin differs from that of metal components such as vacuum interrupters. When the temperature changes, this difference may cause stress to be generated inside the solidified electrode, leading to cracking and other problems. This will not only affect the insulation performance of the solidified electrode, but may also damage its structural integrity. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-3 This utility model provides a technical solution:

[0023] See Figure 1 and Figure 3 As shown, a multifunctional solid-sealed pole includes a housing 1, inside which a vacuum interrupter 2 is integrally formed. A multifunctional layer is provided between the vacuum interrupter 2 and the housing 1. The multifunctional layer includes a resin base layer 5 that is attached to the outer arc wall of the vacuum interrupter 2. The resin base layer 5 contains rubber particles 11 and high-temperature resistant functional groups 12. Carbon fiber bundles 10 are laid flat along the latitudinal direction on the resin base layer 5.

[0024] In the specific implementation process, the multifunctional layer is mainly composed of a resin base layer 5 that is closely attached to the outer arc wall of the vacuum interrupter 2. As the base material of the multifunctional layer, the resin base layer 5 has good insulation performance and mechanical strength, which can effectively protect the vacuum interrupter 2 from the influence of the external environment. Rubber particles 11 and high-temperature resistant functional groups 12 are further added inside the resin base layer 5. The addition of rubber particles 11 makes the resin base layer 5 have better elasticity and impact resistance while maintaining its original performance. The introduction of high-temperature resistant functional groups 12 significantly improves the high-temperature resistance of the resin base layer 5, enabling it to maintain stable performance in high-temperature environments. In addition, carbon fiber bundles 10 are laid flat along the weft direction in the resin base layer 5. As a high-performance reinforcing material, carbon fiber bundles 10 have extremely high strength and modulus, which can effectively improve the mechanical properties of the resin base layer 5. At the same time, the laying method of carbon fiber bundles 10 also enables the multifunctional layer to distribute stress more evenly when subjected to external forces, thereby further improving the overall strength and stability of the solidified pole.

[0025] See Figure 3As shown, the multifunctional layer also includes a reinforcing fiber layer 6, a heat-resistant layer 7, a protective layer 8, and a polyester rubber layer 9, which are radially arranged sequentially from the outer wall of the resin base layer 5. The resin base layer 5, reinforcing fiber layer 6, heat-resistant layer 7, protective layer 8, and polyester rubber layer 9 are all bonded together with adhesive. In specific implementation, the resin base layer 5 serves as the foundation of the multifunctional layer. The resin base layer 5 possesses excellent insulation properties and mechanical strength, providing stable support for the entire multifunctional layer. The reinforcing fiber layer 6 is located adjacent to the resin base layer 5 and is composed of carbon fiber, glass fiber, etc. The main function of this layer is to further improve the mechanical properties of the multifunctional layer, including tensile strength, compressive strength, and shear strength, thereby enhancing the overall stability of the solidified electrode. The heat-resistant layer 7 is located outside the reinforcing fiber layer 6 and is made of high-temperature resistant material. The main function of the heat-resistant layer 7 is to withstand thermal stress under high-temperature conditions, prevent heat damage to the internal structure, and ensure that the solidified electrode can still function normally under high-temperature conditions. The protective layer 8, immediately following the heat-resistant layer 7, primarily provides additional physical and chemical protection. Made of polytetrafluoroethylene (PTFE), it resists corrosion, abrasion, and impact from the external environment, extending the service life of the sealed electrode. The polyester rubber layer 9, as the outermost layer of the multifunctional layer, possesses excellent elasticity and sealing properties. It effectively isolates moisture, dust, and harmful gases from the external environment and acts as a buffer against impacts, protecting the internal structure from damage. The resin base layer 5, reinforcing fiber layer 6, heat-resistant layer 7, protective layer 8, and polyester rubber layer 9 are all bonded together with adhesives, ensuring a tight bond between layers and preventing the risk of interlayer peeling and detachment, thereby improving the overall strength and stability of the multifunctional layer.

[0026] See Figure 1 and Figure 2 As shown, the outer arc wall of the shell 1 is provided with reinforcing ribs 3 at both the upper and lower ends, and the reinforcing ribs 3 are distributed in a spiral shape. The bottom of the shell 1 is provided with a base 4. In the specific implementation process, the main function of the reinforcing ribs 3 is to increase the mechanical strength of the shell 1, so that it can resist greater external forces and pressures. Compared with traditional straight or grid-shaped reinforcing ribs 3, the spiral reinforcing ribs 3 can transmit stress more evenly when subjected to external forces, thereby reducing the risk of local stress concentration.

[0027] See Figure 3As shown, a multifunctional solid-sealed electrode post is disclosed. The high-temperature resistant functional group 12 is composed of materials such as piperazine, triazine, heteroepoxide, and graphene. The carbon fiber bundle 10 is inclined at a 45-degree angle. The surface of the shell 1 is coated with a hydrophobic polymer coating. The resin base layer 5 is made of tough epoxy resin, and a polymer expansion agent is contained within the resin base layer 5. In specific implementation, the high-temperature resistant functional group 12 is carefully composed of materials such as piperazine, triazine, heteroepoxide, and graphene. These materials can improve the stability and reliability of the multifunctional solid-sealed electrode post in high-temperature environments. The 45-degree inclined arrangement of the carbon fiber bundle 10 in the resin base layer 5 helps optimize the mechanical properties of the material. Especially when subjected to shear force, the high strength and modulus of the carbon fiber bundle 10 can effectively improve the shear strength and toughness of the resin base layer 5. The surface of the shell 1 is coated with a hydrophobic polymer coating, which can prevent moisture and other humidity from penetrating into the solid-sealed electrode post, thereby protecting the internal structure from corrosion and damage. The hydrophobic polymer coating usually has good waterproof performance and chemical stability, and can maintain its performance in harsh environments. The resin base layer 5 is made of tough epoxy resin, which possesses excellent mechanical properties and chemical stability, enabling it to withstand significant stress and deformation without cracking. Furthermore, the tough epoxy resin exhibits good insulation and corrosion resistance, meeting the stringent requirements of power systems for solid-sealed poles. A polymeric expanding agent is incorporated within the resin base layer 5. This agent rapidly expands upon heating, forming a dense foam structure that effectively isolates heat and flame propagation, contributing to improved safety and reliability of the solid-sealed pole under extreme conditions such as fires.

[0028] Working principle:

[0029] Step 1: The housing 1 serves as the main body of the solid-sealed pole, and an integrally formed vacuum interrupter 2 is formed inside to realize the circuit interruption and arc extinguishing functions. The multi-functional layer is set between the vacuum interrupter 2 and the housing 1, and is mainly composed of a resin base layer 5. Rubber particles 11 and high-temperature resistant functional groups 12 are added inside the resin base layer 5 to improve its elasticity and high-temperature resistance. The carbon fiber bundle 10 is laid flat in the resin base layer 5 along the weft direction to enhance the mechanical properties of the multi-functional layer.

[0030] Step 2: The resin base layer 5 provides good insulation and mechanical strength, serving as the foundation for the multifunctional layer. The reinforcing fiber layer 6 further improves the mechanical properties of the multifunctional layer and enhances the overall stability of the solidified pole. The heat-resistant layer 7 is made of high-temperature resistant material, which can withstand thermal stress under high-temperature environments and prevent heat from damaging the internal structure. The protective layer 8 is made of polytetrafluoroethylene, providing additional physical and chemical protection against corrosion, wear, and impact from the external environment. The polyester rubber layer 9, as the outermost layer, has good elasticity and sealing performance, isolating moisture, dust, and harmful gases from the external environment, while also acting as a buffer when subjected to external impact. The outer arc wall of the shell 1 is provided with spirally distributed reinforcing ribs 3 at both ends, increasing the mechanical strength of the shell 1 and enabling it to resist greater external forces and pressures. The base 4 is set at the bottom of the shell 1, providing stable support.

[0031] Step 3: The high-temperature resistant functional group 12 is composed of materials such as piperazine, triazine, heteroepoxide, and graphene, which improves the stability and reliability of the solid-sealed electrode in high-temperature environments. The carbon fiber bundle 10 is set at a 45-degree angle to optimize the mechanical properties of the material, especially when subjected to shear force. The surface of the shell 1 is coated with a polymer hydrophobic coating to prevent moisture and other moisture from penetrating into the solid-sealed electrode and protect the internal structure from corrosion and damage. The resin base layer 5 is made of tough epoxy resin, which has excellent mechanical properties and chemical stability, and meets the strict requirements of the power system for solid-sealed electrodes. A polymer expansion agent is set in the resin base layer 5, which expands rapidly when heated to form a dense foam structure, which isolates the spread of heat and flame, and improves the safety and reliability of the solid-sealed electrode under extreme conditions.
