Description

Technical Field

[0001] This utility model belongs to the technical field of high-voltage fuse equipment, specifically relating to a high-voltage fuse that is easy to wire. Background Technology

[0002] High-voltage fuses, as crucial protective devices in power systems, are widely used in power grids, industrial power equipment, and other high-voltage power systems. Their primary function is to rapidly disconnect the circuit in the event of overload or short circuit, preventing equipment damage and fires. However, in practical applications, the wiring process for high-voltage fuses is often complex, requiring advanced technical skills and strict operating procedures to ensure the reliability and safety of the wiring connections. Traditional high-voltage fuse wiring methods typically involve multiple mechanical steps, which are time-consuming and labor-intensive, and carry the risk of loose or detached wiring, affecting the stable operation of the equipment. Therefore, developing a high-voltage fuse that is easy to wire and highly reliable is of great significance for improving the operating efficiency and safety of power systems.

[0003] Existing high-voltage fuses have several shortcomings in their wiring process. First, traditional wiring methods are complex and time-consuming, requiring multiple mechanical steps to complete the line connection, increasing the workload of installation and maintenance. Second, the reliability of the line connection is low, and faults can easily occur due to loosening or detachment of the wires, affecting the normal operation of the power system. Furthermore, the protective structure of traditional high-voltage fuses is relatively simple and cannot effectively prevent the line from detaching due to external forces during use, increasing safety hazards. Therefore, we propose a high-voltage fuse with convenient wiring. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0025] Please see Figures 1 to 3 This utility model provides a technical solution: a high-voltage fuse with convenient wiring, including a body mechanism 1, characterized in that: the body mechanism 1 includes a resistor 11, both ends of the resistor 11 are provided with threaded grooves 12, a support plate 13 is provided on the resistor 11, a connecting frame 14 is provided on the outer surface of the support plate 13, a connecting bracket 16 is provided at the end of the connecting frame 14 away from the support plate 13, a rivet 15 is provided between the support plate 13 and the connecting bracket 16, a connecting rod 17 is provided on the connecting bracket 16, and a wiring mechanism 2 is provided on the outer surface of the resistor 11;

[0026] The wiring mechanism 2 includes a threaded rod 21, with a limit cap 22 at one end. A spring 23 is provided on the outer surface of the threaded rod 21, and a protective cylinder 24 is provided on one end of the spring 23. A spring piece 26 is provided on the protective cylinder 24, and a leakage hole 25 is provided on the side of the protective cylinder 24 away from the spring piece 26. One end of the support plate 13 is fixedly connected to the resistor 11. The inner surface of the connecting frame 14 is nested within the outer surfaces of the support plate 13 and the connecting frame 16. A rivet 15 passes through the connecting frame 14 for fixation. On the support plate 13 and the connecting frame 16, the two ends of the connecting rod 17 are respectively connected between the two connecting frames 16. One end of the threaded rod 21 is fixed in the threaded groove 12 of the resistor 11 by threaded rotation. One side of the limit cap 22 is fixedly connected to one end of the threaded rod 21. One end of the spring 23 is fixedly connected to the limit cap 22. The end of the spring 23 away from the limit cap 22 is fixedly connected to the protective cylinder 24. The two ends of the spring piece 26 are respectively connected between the protective cylinder 24 and the support plate 13.

[0027] In practical use, resistor 11 allows connecting rod 17 to form a series resistance between connecting frame 16, connecting frame 14, support plate 13, and resistor 11. However, resistor 11 is usually exposed to the outside environment, requiring workers to protect the wire interface of resistor 11 using other methods, such as wrapping the interface with special tape. This method increases the worker's load and can easily lead to distraction and danger when working at heights. This fuse, however, has a corresponding hole 25 on the protective cylinder 24. Workers can directly connect the wire to resistor 11 through the hole 25. The spring 26 and spring 23 on the protective cylinder 24 can press the two protective cylinders together to fix the wire and prevent it from falling off during use, thus improving its practicality.

[0028] like Figure 1 - Figure 4 As shown, a heat dissipation mechanism 3 is provided on the protective cylinder 24. The heat dissipation mechanism 3 includes a heat dissipation frame 31. Protective nets 32 are provided on both sides of the heat dissipation frame 31. A fan 33 is provided in the heat dissipation frame 31. The outer surface of the heat dissipation frame 31 is nested in the protective cylinder 24. The outer surface of the fan 33 is installed in the heat dissipation frame 31. The outer surface of the protective net 32 ​​is nested in the heat dissipation frame 31.

[0029] To further enhance its practicality in actual use, a corresponding heat dissipation mechanism 3 is provided on the protective cylinder 24. The operator can connect the fan 33 to the resistor 11 to make the fan 33 work and dissipate heat from the resistor 11, which further enhances its practicality in actual use.

[0030] The working principle of the above embodiment is as follows: In actual use, the resistor 11 enables the connecting rod 17 to form a series resistance between the connecting frame 16, the connecting frame 14, the support plate 13, and the resistor 11. However, the resistor 11 is usually exposed to the external environment, which requires additional protection for the interface of its connected wires. The traditional method is to use special tape to wrap around the interface for protection, but this method increases the load on workers and may cause danger due to distraction when working at height.

[0031] To address this issue, the fuse features a perforation 25 on the protective sleeve 24, allowing operators to directly pass the wire through the perforation 25 and connect it to the resistor 11. The spring clip 26 and spring 23 on the protective sleeve 24 press against each other, securing the wire and preventing it from detaching during use, thus improving the equipment's practicality and safety.

[0032] To further enhance its performance in practical use, a heat dissipation mechanism 3 is also installed on the protective casing 24. Operators can connect a fan 33 to the resistor 11, energizing the fan 33 to effectively dissipate heat from the resistor 11. This not only prevents the resistor from being damaged by overheating but also improves the reliability and stability of the equipment during long-term use. Through these improvements, the practicality and safety of the fuse in actual use have been significantly enhanced.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
