Description

Technical Field

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

[0002] A solid-insulated pole is a modular component formed by encapsulating a vacuum interrupter (vacuum bubble), conductive circuit (contacts, conductive rod), and insulating support structure using an automated pressure gel (APG) process. Its design aims to eliminate the air insulation defects of traditional exposed conductors and adapt to the needs of power equipment in complex environments.

[0003] Existing plug-in solid-sealed terminals have few fixing points when connected to the connector bar, making them prone to loosening during prolonged use. This leads to increased contact resistance (potentially several times the normal value), generating Joule heat (Q = I²Rt) when current flows, causing localized high temperatures, accelerating the aging of insulation materials, and even burning them out. Furthermore, the high temperature at the loose point may ignite surrounding materials (e.g., epoxy resin decomposes at approximately 300°C), potentially escalating into an arc fault in enclosed switchgear, causing equipment explosions or fires. If loosening leads to a complete disconnection, it may cause regional power outages, resulting in significant damage to grid stability or industrial production lines.

[0004] Therefore, the applicant has made beneficial designs and found a way to solve the above problems. The technical solution to be introduced below is generated in this context. Utility Model Content

[0026] To avoid excessive and unnecessary details, well-known structures or functions will not be described in detail in the following embodiments.

[0027] like Figure 1-6 As shown, it is a structural schematic diagram of a securely connected sealing pole according to a preferred embodiment of the present invention.

[0028] In this embodiment, the device includes an electrode body 1 and a connecting strip 2. The electrode body 1 has an inner cavity 3. A connecting tube 4 is provided at the front of the electrode body 1. The connecting tube 4 has a plug-in cavity 5 communicating with the inner cavity 3. A connecting groove 6 is provided at the front of the plug-in cavity 5. Several positioning holes 7 are provided on the rear wall of the connecting groove 6. A through hole 8 is provided at the top of the plug-in cavity 5 through the connecting tube 4. The through hole 8 is a circular hole. A boss 9 is provided around the center of the top opening of the through hole 8. A bracket 10 is integrally provided at the top of the connecting tube 4. The bracket 10 has an inverted "U" shaped structure. A sliding rod 11 is vertically slidable on the bracket 10. A spring 12 is sleeved on the sliding rod 11. An arc-damping cover 13 is provided at the bottom of the sliding rod 11. The arc-damping cover 13 covers the boss 9. Outside the platform 9, the through hole 8 is arc-isolated by an arc-isolation cover 13. The bottom of the arc-isolation cover 13 is provided with a fixing rod 14. The connecting strip 2 includes a plug-in strip 15. The surface of the plug-in strip 15 is provided with a fixing hole 16. The front of the plug-in strip 15 is provided with a connecting block 17. The front of the connecting block 17 is provided with a fixing strip 18. The rear of the connecting block 17 is provided with several positioning posts 19. During connection, the plug-in strip 15 is inserted into the plug-in cavity 5, the connecting block 17 is embedded in the connecting groove 6, the several positioning posts 19 are respectively inserted into several positioning holes 7, and the fixing rod 14 is inserted into the fixing hole 16. Through multiple fixing structures, the connection between the pole body 1 and the connecting strip 2 is more stable, avoiding loosening during long-term use and ensuring connection safety.

[0029] In this embodiment, the two ends of the spring 12 abut against the bracket 10 and the arc-blocking cover 13 respectively. The spring force of the spring 12 provides a downward force to the arc-blocking cover 3, so that the arc-blocking cover 3 covers and presses against the outside of the boss, preventing the electric arc from leaking out from the through hole, and keeping the fixing rod 14 inserted in the fixing hole 16.

[0030] In this embodiment, the through hole 8, boss 9, slide rod 11, arc-blocking cover 13, and fixing rod 14 are arranged on the same axis, so that the slide rod 11, arc-blocking cover 13, and fixing rod 14 move in the same direction, and the fixing rod 14 passes through the through hole 8 and is inserted into the fixing hole 16.

[0031] In this embodiment, the top of the slide bar 11 is provided with a pull block 20. Pulling the pull block 20 causes the slide bar 11 to move upward, and the fixing rod 14 is pulled out from the fixing hole 16. The plug-in strip 15 can then be pulled out from the plug-in cavity 5, thus completing the disassembly of the connecting strip 2 and the pole body 1.

[0032] In this embodiment, the slide rod 11, the arc-blocking cover 13, the fixing rod 14, and the pull block 20 are all made of polytetrafluoroethylene (PTFE), which has high strength, high temperature resistance, and good insulation.

[0033] The present invention provides a stable and securely sealed pole. Its installation, connection, or setting methods are all common mechanical methods, and any method that can achieve its beneficial effects can be implemented.

[0034] All technologies not described in detail in this utility model are known technologies. Those skilled in the art can easily implement this utility model based on their understanding of this specification, and the contents shown in the accompanying drawings are part of this specification.

[0035] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present utility model. It should not be construed that the specific implementation of the present utility model is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present utility model, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted by the present utility model.
