Description

Technical Field

[0001] This utility model relates to the technical field of circuit protection equipment, and in particular to an environmentally friendly cabinet fuse tube. Background Technology

[0002] In the field of circuit protection equipment technology, environmental protection cabinets are important protection devices for circuit systems. The performance of the fuse tube inside the cabinet directly affects the safety and stability of circuit operation. However, existing fuse tubes have many problems in practical applications and cannot meet the needs of environmental protection cabinets. First, the existing fuse holders have an unreasonable structural design for the components used to position the fuse and connect external cables. They lack a dedicated, precise positioning and connection structure, leading to potential positional misalignment of the fuse during installation, affecting circuit continuity stability, and increasing the risk of poor contact when connecting external cables, thus increasing the risk of circuit failure. Furthermore, these components are exposed to air for extended periods, making them susceptible to oxidation and corrosion, shortening their lifespan and requiring frequent replacement, thus increasing operating costs. Second, the current fuse holders lack an effective emergency connection structure. When a circuit failure occurs in the environmental protection cabinet, such as a main circuit disconnection, a temporary emergency circuit cannot be quickly established, causing the circuit system to remain offline for an extended period during fault handling. This affects the normal operation of related equipment and reduces the emergency handling capability of the circuit system. Therefore, these problems need to be addressed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] Example: See Figures 1 to 4 This utility model includes a fuse tube body 1, which facilitates the installation of the fuse and provides a location for overcurrent fuse blowing. The fuse tube body 1 also facilitates the quick insertion of the fuse tube body 1 into the matching electrical cabinet using a positioning arc plate 2. An arc-shaped positioning arc plate 2 is installed at the front end of the fuse tube body 1, providing a quick insertion and removal positioning structure. A positioning platform 3 is fixedly connected to the lower rear end of the fuse tube body 1. A positioning groove is formed at the front end of the lower part of the positioning platform 3, and a mounting hole is formed at the rear end of the lower part of the positioning platform 3. The mounting hole penetrates both the fuse tube body 1 and the positioning platform 3. The positioning platform 3 assists the positioning arc plate 2 in ensuring the quick insertion and removal capability of the fuse tube body 1. The positioning platform 3, together with a metal block 7, provides an emergency reserve position for the electrical cabinet. A first mounting block is sleeved on the outer rear end of the fuse tube body 1, and a connecting plate 4 is installed on the rear end face of the first mounting block. A fixing hole is provided in the lower center of the connecting plate 4, and multiple equidistant connecting holes are also provided in the connecting plate 4. The connecting plate 4 facilitates the connection of subsequent connecting pipes 10 and connectors 5 via external components. The connecting plate 4 is fixed to the fuse cylinder body 1 and connectors 5 via external bolts, connecting holes, a first mounting block, and a second mounting block. A connecting pipe 10 with matching mounting holes and fixing holes is installed below the fuse cylinder body 1. The longitudinal cross-section of the connecting pipe 10 is L-shaped, and a second mounting block is sleeved on the outer rear end of the connecting pipe 10. The connecting pipe 10 facilitates the subsequent connection of connectors 5 to limit the cable 8. Multiple mounting grooves 6 are equidistantly provided on the inner wall of the rear end of the fuse cylinder body 1. The mounting grooves 6 facilitate the positioning of subsequent external components and can also be used for positioning and mounting the fuse wire structure. The front end of the fuse cylinder body 1 communicates with the positioning arc plate 2. A metal block 7 is installed inside the front end of the fuse cylinder body 1. The metal block 7 has multiple first threaded holes longitudinally and equidistantly opened on the rear end face, and a second threaded hole is opened in the middle of the front end face. The metal block 7 facilitates the use of the first threaded holes at the rear end and the external bolts to position the fuse, and the second threaded hole at the front end connects to the cables inside the electrical cabinet with the external bolts. The metal block 7 is coated with an anti-oxidation coating.

[0015] In this utility model, a connector 5 is fixedly connected to the rear end of the connecting pipe 10, which facilitates connection with external components through the holes of the external components; and a cable 8 is installed inside the connecting pipe 10, which facilitates the transmission of electrical energy from inside the electrical cabinet to external components; a rectangular connecting groove is opened at the front end of the connecting pipe 10, which communicates with the inner cavity of the connecting pipe 10, and a metal plate 9 is installed on the connecting pipe 10 in conjunction with the connecting groove. The other end of the metal plate 9 is connected to the cable 8, which facilitates the provision of an emergency connection end in case of problems with the electrical cabinet.

[0016] Working Principle: Before using this utility model, a comprehensive inspection of each key component is required to ensure the stability and safety of subsequent use: Check whether the connection structure between the fuse cylinder body 1 and the positioning arc plate 2 is stable to avoid affecting subsequent insertion, removal and use due to loose connection; Check whether the metal block 7 (which is coated with an anti-oxidation coating to reduce the risk of oxidation, but still needs to be checked regularly) and the metal sheet 9 related to the positioning platform 3 are oxidized. If oxidation is present, it will affect the conductivity and needs to be dealt with in time; At the same time, check whether the connecting plate 4 is firmly connected to the fuse cylinder body 1 and the connecting pipe 10, because the connecting plate 4 needs to be fixed to the fuse cylinder body 1 and the connector 5 through external bolts, connecting holes, the first mounting block (sleeved on the outer side of the rear end of the fuse cylinder body 1) and the second mounting block (sleeved on the outer side of the rear end of the connecting pipe 10). Its connection stability is crucial. After all inspection items are confirmed to be correct, the fuse installation process begins: the external fuse is inserted into the fuse tube body 1, into which multiple mounting slots 6 (which facilitate positioning and installation of the fuse) are equidistantly opened on the inner wall of the rear end. Then, the fuse is connected and fixed through multiple first threaded holes equidistantly opened longitudinally on the rear end face of the metal block 7. This ensures the stability of the fuse within the fuse tube body 1, while the fuse tube body 1 itself provides a suitable location for fuse installation and for overcurrent tripping. During the fuse installation process, to further improve the safety and service life of the fuse, inert gas can be first introduced into the fuse tube body 1 before placing the fuse. After the fuse is installed, the metal fuse, together with the external circuit components, will form a complete electrical circuit. The fuse is installed in the connector 5 (fixed to the rear end of the connecting tube 10, which facilitates connection with external components through the holes of the external components) and the connecting tube 10 (which has an L-shaped longitudinal cross-section to facilitate the connection of the connector 5 to limit the cable 8, and the front end of the connecting tube 10 has a rectangular connecting groove that communicates with the inner cavity. A metal plate 9 is installed in the connecting groove, and the other end of the metal plate 9 is connected to the cable 8 installed in the connecting tube 10, which can provide an emergency connection end when the electrical cabinet has problems later). Finally, after completing all the above operations, wait for the product to be connected to the electrical cabinet and external components before it can be put into use: With the help of the arc-shaped positioning plate 2 installed at the front end of the fuse tube body 1 (which provides a positioning structure for quick insertion and removal of the fuse tube body 1) and the positioning platform 3 fixed to the lower rear end of the fuse tube body 1 (the positioning platform 3 has a positioning groove at the lower front end and an installation hole that penetrates the fuse tube body 1 and the positioning platform 3 at the lower rear end, which helps the positioning plate 2 to ensure the quick insertion and removal capability of the fuse tube body 1, and also provides an emergency reserved position for the electrical cabinet in conjunction with the metal block 7), the fuse tube body 1 is quickly inserted into the paired electrical cabinet. At the same time, through the fixing hole in the middle of the lower part of the connecting plate 4 and the relevant structure of the positioning platform 3, a stable connection with the electrical cabinet and external components is achieved in conjunction with the external components. Thus, the entire process from product preparation to formal use is completed.
