[0002] Vacuum high-voltage pulse insulation structure is a key insulation system used in high-voltage pulse equipment (such as pulse power devices and vacuum circuit breakers). Its core function is to maintain stable insulation performance under high-voltage pulse conditions and prevent breakdown or flashover.

[0003] Conventional vacuum high-voltage pulse insulation structures often use a single insulating material or a simple combination structure. When faced with complex and ever-changing voltage pulse environments, the stability and reliability of their insulation performance are difficult to guarantee. At the same time, they lack structural protection, which affects the normal operation of the entire equipment and may even cause safety accidents. Utility Model Content

[0004] The purpose of this invention is to provide a vacuum high-voltage pulse insulation structure to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vacuum high-voltage pulse insulation structure, comprising an adjustment frame assembly and a protective mesh frame. An insulating component is vertically installed on the front side of the adjustment frame assembly, and a supporting component is vertically connected to the side of the insulating component away from the adjustment frame assembly. The protective mesh frame surrounds the insulating component and the supporting component. The protective mesh frame includes a buffer shielding mesh frame, a protective coating, and mating pins. The outer surface of the buffer shielding mesh frame is coated with a protective coating, and two sets of mating pins are symmetrically arranged horizontally on each side of the middle of the buffer shielding mesh frame near the insulating component.

[0006] Furthermore, the adjustment frame assembly includes a support guide rail, a damping slider, a limit bolt, a first assembly frame, and a second assembly frame. The damping slider is horizontally connected and installed on the surface of the support guide rail, and the limit bolts are symmetrically and vertically installed on the top of the damping slider. The first assembly frame is connected and installed on the side of the damping slider away from the support guide rail, and the second assembly frame is connected and installed on the side of the first assembly frame away from the damping slider.

[0007] Furthermore, the support guide rail and the damping slider are connected to each other using a slotted embedded structure, and the damping slider and the limit bolt are connected to each other by threads. The connection between the first assembly frame and the second assembly frame is provided with two sets of holes for bolt installation at both ends, and the connection between the first assembly frame and the damping slider is provided with two sets of holes for bolt installation at both ends.

[0008] Furthermore, the insulating component includes a vacuum high-voltage insulating tube, an insulator, a first terminal, a second terminal, and a mounting base. Insulators are installed at both the upper and lower ends of the vacuum high-voltage insulating tube. The upper end of the vacuum high-voltage insulating tube is connected to the first terminal via an insulator, and the lower end of the vacuum high-voltage insulating tube is connected to the second terminal via an insulator. A mounting base is horizontally arranged on the side surface of the first terminal and the second terminal near the supporting component.

[0009] Furthermore, both the first and second terminals are integrally integrated with the base, and both the first and second terminals are made of copper-chromium alloy.

[0010] Furthermore, the supporting component includes a double-segment spring telescopic rod, a connecting end, and an insulating coating. Both the upper and lower ends of the double-segment spring telescopic rod are provided with connecting ends, and the surface of the double-segment spring telescopic rod is coated with an insulating coating.

[0011] Furthermore, both the docking end and the junction of the assembly seat are provided with holes for bolt installation, and the insulating coating is applied using a silicone rubber coating spray.

[0012] Furthermore, the buffer shielding mesh frame itself is made of aluminum-magnesium alloy, the protective coating is made of plasma-sprayed aluminum oxide, and the two ends of the first assembly frame are provided with holes for inserting the docking stakes, and the docking stakes are provided with holes for bolt installation in the middle.

[0013] This invention provides a vacuum high-voltage pulse insulation structure, which has the following beneficial effects: 1. This utility model, through the unique design of the protective mesh frame, achieves effective protection and electromagnetic shielding for key internal components of the vacuum high-voltage pulse insulation structure. Specifically, the buffer shielding mesh frame is made of aluminum-magnesium alloy, which not only has the characteristics of being lightweight and high-strength, but also effectively absorbs and disperses external impact forces, protecting the internal insulation components from mechanical damage. At the same time, the plasma-sprayed aluminum oxide protective coating on its surface further enhances the corrosion resistance and insulation performance of the mesh frame, effectively resisting the erosion of the equipment by harsh environments. In addition, the design of the docking stakes allows the protective mesh frame to be stably installed on the adjustment frame assembly, and the hole structure for bolt installation achieves a reliable connection with the first assembly frame, ensuring the stability and safety of the entire insulation structure. This series of designs work together to significantly improve the insulation performance and reliability of the vacuum high-voltage pulse insulation structure under high-voltage pulse conditions, providing a strong guarantee for the stable operation of high-voltage pulse equipment.

[0014] 2. This utility model, through the construction of the adjustment frame assembly, enables the insulating component to have good adjustment and adaptability. Specifically, the slotted embedded connection between the support guide rail and the damping slider, and the threaded connection between the damping slider and the limit bolt, together constitute a flexible and stable adjustment system. This design allows the damping slider to slide smoothly on the support guide rail and to be precisely locked in position by the limit bolt, thereby realizing fine adjustment of the position of the insulating component and the support component, meeting the needs of different working scenarios. At the same time, the first and second assembly frames are tightly connected to the damping slider and the insulating component through the hole structure of bolt installation. This detachable connection method not only facilitates the installation and maintenance of the equipment, but also enhances the flexibility and scalability of the entire structure, enabling the vacuum high-voltage pulse insulation structure to adapt to a variety of complex environments and high-intensity working conditions.

[0015] 3. This utility model, through the optimized design of the supporting components, further enhances the load-bearing capacity and insulation stability of the vacuum high-voltage pulse insulation structure. The use of a double-segment spring telescopic rod allows the supporting components to elastically expand and contract according to actual working needs, effectively absorbing and mitigating the impact of external impacts on the insulation components, thereby protecting them from damage caused by excessive stress. Simultaneously, the mating ends of the double-segment spring telescopic rod, through cooperation with the bolt mounting holes on the mounting base of the insulation components, achieve a stable connection between the supporting components and the insulation components. Furthermore, the silicone rubber insulating coating on the surface of the double-segment spring telescopic rod not only enhances the insulation performance of the supporting components themselves but also improves their weather resistance and anti-aging capabilities, ensuring the stability and reliability of the supporting components during long-term use. These design features work together to enable this vacuum high-voltage pulse insulation structure to maintain excellent insulation performance and mechanical stability under high-voltage pulse environments.

[0018] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0019] like Figures 1 to 5 As shown, a vacuum high-voltage pulse insulation structure includes an adjusting frame assembly 1 and a protective mesh frame 4. An insulating member 2 is vertically installed on the front side of the adjusting frame assembly 1, and a supporting member 3 is vertically connected to the side of the insulating member 2 away from the adjusting frame assembly 1. The protective mesh frame 4 surrounds the insulating member 2 and the supporting member 3. The protective mesh frame 4 includes a buffer shielding mesh frame 401, a protective coating 402, and mating pins 403. The outer surface of the buffer shielding mesh frame 401 is coated with the protective coating 402, and two sets of mating pins 403 are symmetrically arranged horizontally on the left and right sides of the middle of the buffer shielding mesh frame 401 near the insulating member 2. The buffer shielding mesh frame 401 itself is made of aluminum-magnesium alloy, and the protective coating 402 is made of plasma-sprayed alumina. The edges of the two ends of the first assembly frame 104 are open. The device is equipped with a hole structure for inserting the docking stake 403, and the docking stake 403 has a hole structure in the middle for bolt installation. By cooperating with the hole structure at both ends of the first assembly frame 104, and utilizing the bolt installation hole structure in the middle of the docking stake 403, the protective net frame 4 and the adjusting frame assembly 1 can be quickly and firmly connected. This connection method is not only simple to operate and greatly shortens the installation time, but also has a firm and reliable connection, effectively avoiding safety hazards caused by loosening. In practical applications, when the equipment is working in a high-voltage pulse environment, this firm connection can ensure that the protective net frame 4 is always tightly surrounded by the insulating component 2 and the supporting component 3, providing continuous and effective protection and electromagnetic shielding for the internal key components.

[0020] like Figures 1 to 5As shown, the adjustment frame assembly 1 includes a support guide rail 101, a damping slider 102, a limit bolt 103, a first assembly frame 104, and a second assembly frame 105. The damping slider 102 is horizontally connected to the surface of the support guide rail 101, and the limit bolts 103 are symmetrically and vertically installed on the top of the damping slider 102. The first assembly frame 104 is connected to the side of the damping slider 102 away from the support guide rail 101, and the second assembly frame 105 is connected to the side of the first assembly frame 104 away from the damping slider 102. The support guide rail 101 and the damping slider 102 are connected to each other using a slotted embedded structure, and the damping slider 102 and the limit bolts 103 are threaded together. The connection points of the first assembly frame 104 and the second assembly frame 105 each have two sets of holes for bolt installation at both ends. The first assembly frame 104 and the damping slider 102... The connection of component 2 has two sets of holes for bolt installation at both ends. The support component 3 includes a double-segment spring telescopic rod 301, a mating end 302, and an insulating coating 303. The double-segment spring telescopic rod 301 has mating ends 302 at both ends, and the surface of the double-segment spring telescopic rod 301 is coated with an insulating coating 303. Holes for bolt installation are provided at the connection between the mating ends 302 and the combination seat 205. The insulating coating 303 is made of silicone rubber. The bolt installation holes at the connection between the mating ends 302 at both ends of the double-segment spring telescopic rod 301 and the combination seat 205 can easily and quickly connect the support component 3 and the insulating component 2 securely. In the actual installation process, simply insert the mating end 302 into the corresponding hole in the combination seat 205 and then tighten it with bolts to complete the reliable connection between the two.

[0021] like Figures 1 to 5As shown, the insulating component 2 includes a vacuum high-voltage insulating tube 201, an insulator 202, a first terminal 203, a second terminal 204, and a mounting base 205. Insulators 202 are installed at both the upper and lower ends of the vacuum high-voltage insulating tube 201. The upper end of the vacuum high-voltage insulating tube 201 is connected to the first terminal 203 via the insulator 202, and the lower end of the vacuum high-voltage insulating tube 201 is connected to the second terminal 204 via the insulator 202. The mounting base 205 is horizontally mounted on the surface of the first terminal 203 and the second terminal 204 near the supporting component 3. The first terminal 203... 03. The second terminal 204 is integrally formed with the combination base 205. Both the first terminal 203 and the second terminal 204 are made of copper-chromium alloy. The integral structure of the first terminal 203 and the second terminal 204 with the combination base 205 enhances the overall structural strength of the insulating component 2 and avoids electrical faults that may be caused by loose connections. At the same time, the use of copper-chromium alloy gives the first terminal 203 and the second terminal 204 excellent conductivity and heat resistance, and can maintain a stable electrical connection even under high temperature and high pressure environments.

[0022] In summary, as Figures 1 to 5 As shown, when using this vacuum high-voltage pulse insulation structure, firstly, the adjustment frame assembly 1 is fixed in the predetermined working position to ensure that the support rail 101 is in a horizontal state, providing a stable foundation for the installation of subsequent components. Next, the damping slider 102 is embedded in the support rail 101. By rotating the limit bolt 103, the position of the damping slider 102 on the support rail 101 is adjusted and locked to ensure that it is stable and does not move. Subsequently, the first assembly frame 104 and the second assembly frame 105 are installed in the corresponding positions of the damping slider 102 and the insulation component 2 respectively through the bolt mounting hole structure, thus completing the assembly of the adjustment frame assembly 1. Next, the vacuum high-voltage insulating tube 201 of the insulating component 2 is connected to the first terminal 203 and the second terminal 204 through the insulator 202, and the assembly seat 205 is horizontally set on the side of the first terminal 203 and the second terminal 204 close to the supporting component 3 for a stable connection. At the same time, the double-segment spring telescopic rod 301 of the supporting component 3 is bolted to the assembly seat 205 on the insulating component 2 through the mating ends 302 at its upper and lower ends to ensure a stable connection between the supporting component 3 and the insulating component 2. Meanwhile, the elastic telescopic characteristics of the double-segment spring telescopic rod 301 allow the supporting component 3 to be adaptively adjusted according to actual working needs, effectively absorbing and mitigating external impact forces. At the same time, the vacuum high-voltage insulating tube 201 is vertically set between the first assembly frame 104 and the second assembly frame 105, and with the tightening action of the bolts, the insulating component 2 is stably fixed on the adjusting frame assembly 1, completing the assembly of the insulating component 2 and the supporting component 3.

[0023] Finally, the buffer shielding mesh frame 401 of the protective mesh frame 4 is inserted into the hole structure at both ends of the first assembly frame 104 through the docking pins 403 on both sides, and the docking pins 403 are fixedly connected to the first assembly frame 104 by bolts, thus completing the installation of the protective mesh frame 4. At this time, the plasma-sprayed alumina protective coating 402 on the outer surface of the buffer shielding mesh frame 401 provides effective electromagnetic shielding and corrosion protection for the internal key components. The entire vacuum high-voltage pulse insulation structure is assembled and can be put into use. In the high-voltage pulse environment, this structure can maintain excellent insulation performance and mechanical stability, providing a strong guarantee for the stable operation of high-voltage pulse equipment.
