Description

Technical Field

[0001] This utility model relates to the field of ceramic insulators, specifically to a ceramic insulator with a spliced ​​multi-layer encapsulation shell. Background Technology

[0002] Ceramic insulators are insulators made of electrical ceramics. They play an important role in the power industry and are mainly used for the external insulation of high-voltage power transmission lines, ultra-high-voltage power transmission lines, and electrical equipment in power plants. Depending on their application, ceramic insulators are mainly divided into insulators used in transmission lines, insulators used in electrical equipment in power plants, and insulating components used in other live parts. Multi-layered ceramic insulators are insulators made of multiple layers of ceramic materials. Their shell structure is complex and contains multiple encapsulation layers to protect internal electronic components and provide electrical isolation.

[0003] A search revealed a ceramic insulator with publication number CN210865759U, specifically disclosing a ceramic insulator including a top tube, an insulator body, and a mounting base. A base is fixedly mounted at the bottom of the mounting base, and a connecting platform is fixedly mounted at the bottom of the base. A fixing bolt is fixedly mounted at the bottom of the connecting platform via a fixing ring. A connecting rod is rotatably mounted at the bottom of the fixing bolt. A bolt is fixedly mounted at the top of the mounting base, and the insulator body is rotatably mounted around the bolt. A top tube is rotatably mounted on the top of the bolt on the top of the insulator body. A ceramic ring is fixedly mounted around the top tube, and a top platform is fixedly mounted on the top of the top tube. An upper retaining ring is rotatably mounted on the top of the top platform via a connecting bolt. This utility model, through a series of structural features, facilitates the installation and disassembly of the device during use, offering advantages such as good insulation performance and optimizing the usage process.

[0004] In the application of existing multi-encapsulated ceramic insulators, due to the different application ranges, some ceramic insulators lacking splicing capabilities cannot meet the usage requirements of certain specific line scenarios. This also leads to the need to replace the ceramic insulator with a matching multi-encapsulated ceramic insulator when facing installation gaps, or to change to a more complex fixing method, increasing the difficulty and cost of installation. Moreover, the multi-encapsulated ceramic insulators in the comparative case mentioned above also lack splicing capabilities. Over the long term, this will adversely affect the structural integrity, installation, and maintenance convenience of the multi-encapsulated ceramic insulators.

[0005] Therefore, it is necessary to invent a ceramic insulator with a spliced ​​multi-encapsulated shell to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a ceramic insulator with a splicing multi-encapsulated shell. Through a first splicing sleeve, splicing groove, splicing block, second splicing sleeve, secondary ceramic insulator body, embedded groove, and contact block, it not only enhances the stability of the connection between the main ceramic insulator body and the secondary ceramic insulator body, but also gives the ceramic insulator splicing capability. This can meet the usage requirements of certain line scenarios. Furthermore, when facing installation gaps, there is no need to replace the ceramic insulator with a matching multi-encapsulated shell, nor to change the complex fixing method; the overall installation is completed directly by extending the ceramic insulator, reducing the difficulty and cost of installation, and improving the structural integrity, installation, and maintenance of the ceramic insulator. The effectiveness of this technology is guaranteed, addressing the issue that in existing multi-encapsulated ceramic insulators, due to their varying application ranges, some lack splicing capabilities and cannot meet the needs of certain specific line scenarios. This leads to the need to replace the multi-encapsulated ceramic insulator with a matching one or to adopt a more complex fixing method when encountering installation gaps, increasing the difficulty and cost of installation. Furthermore, the multi-encapsulated ceramic insulators in the aforementioned comparative case also lack splicing capabilities, which will adversely affect the structural integrity, installation, and maintenance convenience of multi-encapsulated ceramic insulators over long-term use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a ceramic insulator with a spliced ​​multi-encapsulated shell, including a main ceramic insulator body for use on a line;

[0008] The first splicing sleeve is set on the top of the main ceramic insulator body and is used to splice with the auxiliary ceramic insulator body. The first splicing sleeve has a splicing groove inside, and a splicing block is movably connected inside the splicing groove. The second splicing sleeve is fixedly installed above the splicing block, and the auxiliary ceramic insulator body is fixedly installed above the second splicing sleeve.

[0009] An embedded groove is provided on the outside of the splicing block to enhance the connection between insulators. An internal thread is passed through the outside of the first splicing sleeve. One end of the internal thread is provided with an abutment block. A torsion spring is provided inside the abutment block. A connecting hardware is fixedly installed on the top of the secondary ceramic insulator body.

[0010] Preferably, the splicing block fixedly installed at the bottom of the second splicing sleeve engages with the splicing groove opened inside the first splicing sleeve, and the splicing block and the splicing groove are used in conjunction.

[0011] Preferably, the abutment block is movably connected to the first splicing sleeve, and the torsion spring is symmetrically arranged about the central axis of the abutment block.

[0012] Preferably, the outer surface of the secondary ceramic insulator body is provided with an inner insulating encapsulation shell, the outer surface of the inner insulating encapsulation shell is provided with an abutment hole, and an encapsulation head is provided on the top of the inner insulating encapsulation shell.

[0013] Preferably, a double-ended bolt passes through the outer surface of the inner insulating encapsulation shell, and a hexagonal nut is movably connected to the outer surface of the double-ended bolt.

[0014] Preferably, an outer insulating shell is provided outside the inner insulating shell, and a threaded abutment rod penetrates the outside of the outer insulating shell, with a fixing knob fixedly installed at one end of the threaded abutment rod.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. This utility model is provided with a first splicing sleeve, a splicing groove, a splicing block, a second splicing sleeve, a secondary ceramic insulator body, an inner groove, and an abutment block. When using this multi-encapsulated ceramic insulator on a specific line, and encountering a large installation gap or a situation where the multi-encapsulated ceramic insulator is not long enough, the main ceramic insulator body and the secondary ceramic insulator body can be connected through the splicing groove of the first splicing sleeve and the splicing block. Then, the inner screw is twisted, causing the inner screw to drive the abutment block to stretch the torsion spring and abut against the inner groove of the splicing block. This not only strengthens the stability of the connection between the main ceramic insulator body and the secondary ceramic insulator body, but also gives the ceramic insulator splicing capability, which can meet the usage requirements of some specific line scenarios. Moreover, when facing an installation gap, there is no need to replace the ceramic insulator with a matching multi-encapsulated ceramic insulator, nor is there a need to change the complex fixing method. The overall installation can be completed directly by extending the ceramic insulator, reducing the difficulty and cost of installation, and ensuring the structural integrity, installation and maintenance convenience of the ceramic insulator.

[0017] 2. This utility model includes an inner insulating shell, a contact hole, a sealing head, a double-ended bolt, a hexagonal nut, an outer insulating shell, a threaded contact rod, and a fixing knob. When using this multi-shell ceramic insulator, the inner insulating shell can be fitted onto the ceramic insulator, followed by the outer insulating shell. Twisting the threaded contact rod allows it to insert into the contact hole of the inner insulating shell. This not only enhances the stability of the connection between the inner and outer insulating shells but also keeps the ceramic insulator stable within the multi-shell structure. Furthermore, the inner and outer insulating shells, along with the sealing head, fulfill the purpose of the multi-shell ceramic insulator, making it more stable in line operation.

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] This utility model provides, for example Figure 1-5 The ceramic insulator shown has a spliced ​​multi-encapsulated shell, including a main ceramic insulator body 1, which is used as an insulator body on the line;

[0028] The first splicing sleeve 2 is set on the top of the main ceramic insulator body 1 and is used to splice with the auxiliary ceramic insulator body 6. The first splicing sleeve 2 has a splicing groove 3 inside, and a splicing block 4 is movably connected inside the splicing groove 3. The second splicing sleeve 5 is fixedly installed above the splicing block 4, and the auxiliary ceramic insulator body 6 is fixedly installed above the second splicing sleeve 5.

[0029] An embedded groove 7 is located on the outside of the splicing block 4 to enhance the connection between insulators. An internal thread 8 passes through the outside of the first splicing sleeve 2. One end of the internal thread 8 is provided with an abutment block 9. A torsion spring 10 is provided inside the abutment block 9. A connecting hardware 11 is fixedly installed on the top of the secondary ceramic insulator body 6. The main ceramic insulator body 1 and the secondary ceramic insulator body 6 can be connected through the splicing groove 3 of the first splicing sleeve 2 and the splicing block 4. Then, the internal thread 8 is twisted to cause the internal thread 8 to drive the abutment block 9 to stretch the torsion spring 10 and abut together in the embedded groove 7 of the splicing block 4.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the splicing block 4 fixedly installed at the bottom of the second splicing sleeve 5 engages with the splicing groove 3 opened inside the first splicing sleeve 2. The splicing block 4 and the splicing groove 3 work together to facilitate the quick splicing of the main ceramic insulator body 1 and the auxiliary ceramic insulator body 6 without delaying the normal line installation and use. The contact block 9 is movably connected to the first splicing sleeve 2. The torsion spring 10 is symmetrically arranged around the central axis of the contact block 9, so that the inner screw 8 drives the contact block 9 to stretch the torsion spring 10 together to abut in the inner groove 7 of the splicing block 4. This enhances the stability of the connection between the main ceramic insulator body 1 and the auxiliary ceramic insulator body 6.

[0031] like Figure 1 , Figure 4 and Figure 5 As shown, the outer surface of the secondary ceramic insulator body 6 is provided with an inner insulating encapsulation shell 12. An abutment hole 13 is opened on the outer surface of the inner insulating encapsulation shell 12. An encapsulation head 14 is provided on the top of the inner insulating encapsulation shell 12. The inner insulating encapsulation shell 12, the outer insulating encapsulation shell 17, and the inner encapsulation head 14 together fulfill the purpose of a multi-encapsulation shell for the ceramic insulator, making the ceramic insulator with this multi-encapsulation shell more stable during line use. A double-ended bolt 15 passes through the outer surface of the inner insulating encapsulation shell 12. A hexagonal nut 16 is movably connected to the outer surface of the double-ended bolt 15. The double-ended bolt 15 and the hexagonal nut 16 facilitate the mating and installation of the two inner insulating encapsulation shells 12. The inner ceramic insulator is encapsulated. An outer insulating shell 17 is provided outside the inner insulating shell 12. A threaded abutment rod 18 passes through the outside of the outer insulating shell 17. A fixing knob 19 is fixedly installed at one end of the threaded abutment rod 18. After the inner insulating shell 12 is put on the ceramic insulator, the outer insulating shell 17 is put on. Twisting the threaded abutment rod 18 allows it to be inserted into the abutment hole 13 of the inner insulating shell 12. This not only enhances the stability of the connection between the inner insulating shell 12 and the outer insulating shell 17, but also keeps the inner ceramic insulator stable inside the multi-encapsulated shell.

[0032] The working principle of this practical application is as follows: First, take out the multi-encapsulated ceramic insulator from the line where installation is required. Based on the current installation requirements and gaps, connect the main ceramic insulator body 1 and the auxiliary ceramic insulator body 6 through the splicing groove 3 of the first splicing sleeve 2 and the splicing block 4. Then, twist the inner screw 8, causing the inner screw 8 to drive the contact block 9 to stretch the torsion spring 10 and abut against the inner groove 7 of the splicing block 4. This not only strengthens the stability of the connection between the main ceramic insulator body 1 and the auxiliary ceramic insulator body 6, but also gives the ceramic insulator splicing capability, which can meet the usage requirements of some specific line scenarios. Next, put the inner insulating encapsulation shell 12 on the outside of the ceramic insulator. Connect the two inner insulating encapsulation shells 12 with double-ended bolts 15 and hexagonal nuts 16 to complete the encapsulation of the internal ceramic insulator. Finally, put on the outer insulating encapsulation shell. 17. Twist the threaded abutment rod 18 to insert it into the abutment hole 13 of the inner insulating shell 12. This not only strengthens the stability of the connection between the inner insulating shell 12 and the outer insulating shell 17, but also keeps the internal ceramic insulator stable inside the multi-encapsulation shell. At the same time, the inner insulating shell 12, the outer insulating shell 17, and the internal encapsulation head 14 fulfill the purpose of the multi-encapsulation shell of the ceramic insulator, making the ceramic insulator of the multi-encapsulation shell more stable in the line. After installation, the connection of the line can be completed through the ceramic insulator connecting hardware 11 for normal use. Finally, after completing the installation and use of all the ceramic insulators of the multi-encapsulation shell according to the above operations, routine maintenance of the device is required. In this way, the use of the ceramic insulator with the spliced ​​multi-encapsulation shell is completed.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
