Description

Technical Field

[0001] This utility model belongs to the technical field of power failure protection devices for power distribution cabinets, specifically a power failure protection device for temperature monitoring of power distribution cabinets. Background Technology

[0002] In modern power systems, distribution cabinets are key equipment for power distribution and control, and their operational stability and safety are of paramount importance. However, because the electrical components inside the distribution cabinet generate heat during long-term operation, failure to effectively monitor and control the temperature may lead to electrical faults or even serious accidents such as fires.

[0003] Traditional temperature monitoring and automatic power-off protection devices for distribution cabinets have several shortcomings. Firstly, the fixed structure is not flexible or stable enough for fuse installation and replacement. Existing devices may not allow for easy adjustment of the relative position between the fuse and the terminal block, leading to cumbersome installation and a high risk of poor contact. Secondly, in terms of protection performance, they lack effective measures against electrical short circuits, high-temperature environments, and fire hazards. Furthermore, the lack of a reasonable structural design makes routine maintenance and repair of the distribution cabinet inconvenient, hindering quick problem identification and resolution.

[0004] In conclusion, developing a temperature monitoring and self-power-off protection device for distribution cabinets that can flexibly adjust its internal structure, effectively fix the fuse, have good protective performance, and is easy to maintain is of great practical significance. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a temperature monitoring and self-power-off protection device for distribution cabinets, which solves the technical problems of insufficient flexibility and stability of the fixing structure in the installation and replacement of traditional fuses.

[0006] The present invention provides a power distribution cabinet temperature monitoring and self-power-off protection device, comprising a power distribution cabinet body. The device is characterized in that a first fixed frame is fixedly connected to the inner side wall of the power distribution cabinet body, and a second fixed frame is slidably connected thereto. An adjustment assembly is provided between the first and second fixed frames to adjust the distance between them. Three sets of wiring blocks are provided on the first fixed frame, and three sets of mounting brackets corresponding to the wiring blocks are provided on the second fixed frame. Connecting plates are provided on the three sets of mounting brackets. A slot is provided at the bottom of each of the three sets of wiring blocks. A fuse is provided on each of the three sets of mounting brackets. A mating groove corresponding to the fuse is provided on each of the three sets of mounting brackets. Two sets of springs that cooperate with the fuse are provided in the mating groove. An auxiliary clamping assembly is provided on each of the three sets of mounting brackets to fix the fuse.

[0007] Preferably, the adjustment assembly includes two sets of telescopic rods mounted on the first fixed frame, and the extended ends of the two sets of telescopic rods are fixedly connected to the second fixed frame.

[0008] Preferably, the auxiliary clamping assembly includes four sets of clamping plates corresponding to the fuse slidably connected on the mounting frame, and clamping springs are provided between the four sets of clamping plates and the mounting frame.

[0009] Preferably, a retractable sealing strip is provided between the four sets of clamping plates and the mounting frame.

[0010] Preferably, the power distribution cabinet body is provided with maintenance doors corresponding to the first fixed frame and the second fixed frame.

[0011] Preferably, the center of the maintenance door is provided by a transparent panel.

[0012] Preferably, the surfaces of the first and second fixing frames are coated with an insulating coating.

[0013] Preferably, the inner surface of the clamping plate is provided with anti-slip texture, and the clamping spring is a high-temperature resistant spring.

[0014] Preferably, the retractable sealing strip is made of fire-resistant material.

[0015] Beneficial effects:

[0016] I. Flexible Adjustment Function: By setting an adjustment component between the first and second fixed frames, and the adjustment component employing two sets of telescopic rods, the distance between the first and second fixed frames can be easily adjusted. This design allows for quick and accurate position adjustment when installing fuses of different specifications or connecting different types of terminal blocks, improving the versatility and adaptability of the device. It effectively solves the inconvenience caused by the fixed structure during installation of traditional devices. When replacing a fuse, the first and second fixed frames separate, causing the connecting plate to separate from the slot. The mounting bracket is then de-energized, allowing for fuse installation and improving the safety performance of this application.

[0017] II. Secure Fuse Fixing: The auxiliary clamping assembly includes four sets of clamping plates and clamping springs on the mounting bracket, providing reliable clamping force to the fuse and ensuring a stable connection during operation, preventing poor contact or power outages caused by loosening. Simultaneously, the inner surface of the clamping plates features anti-slip textures, further increasing friction with the fuse and improving clamping stability.

[0018] III. Enhanced Protection Performance: The surfaces of the first and second fixing frames are coated with an insulating coating, effectively preventing electrical short circuits, improving the electrical safety of the device, and reducing the risk of failures caused by electrical short circuits. The clamping springs are made of high-temperature resistant springs, which can maintain good elasticity in high-temperature environments, ensuring that the auxiliary clamping components can still work normally when the internal temperature of the distribution cabinet is high, maintaining stable clamping of the fuse. The retractable sealing strip is made of fireproof material, which can play a certain role in fire isolation when an electrical fault causes a fire, preventing the spread of fire and buying time for personnel evacuation and fire rescue.

[0019] IV. Facilitates Maintenance and Repair: The distribution cabinet body is equipped with maintenance doors corresponding to the first and second fixed frames, greatly facilitating daily maintenance and repair of the internal components. Workers can quickly access the parts requiring maintenance without disassembling numerous components, improving work efficiency. A transparent panel is installed in the center of the maintenance door, allowing workers to observe the internal operation of the distribution cabinet at any time without opening the door, promptly identifying potential problems such as whether fuses have blown or whether electrical components are abnormal, thus achieving real-time monitoring of the distribution cabinet's operating status.

[0035] As an optional embodiment of Example 1, the retractable sealing strip is made of fire-resistant material.

[0036] When in use, the main body of the distribution cabinet: The main body of the distribution cabinet 1 is the outer shell of the entire device, providing protection and a mounting base for the internal electrical components.

[0037] First fixing frame and second fixing frame: The first fixing frame 2 is fixedly connected to the inner wall of the power distribution cabinet body 1, and the second fixing frame 3 is slidably connected to the inner wall of the power distribution cabinet body 1. The surfaces of the first fixing frame 2 and the second fixing frame 3 are coated with an insulating coating to prevent electrical short circuits. An adjustment assembly is provided between the two, which includes two sets of telescopic rods 11. The extended ends of the telescopic rods 11 are fixedly connected to the second fixing frame 3.

[0038] Terminal blocks and mounting brackets: The first fixed bracket 2 is provided with three sets of terminal blocks 4, each terminal block 4 has a slot 7 at the bottom. The second fixed bracket 3 is provided with three sets of mounting brackets 5 corresponding to the terminal blocks 4. Each set of mounting brackets 5 is provided with a connecting plate 6. Each set of mounting brackets 5 is provided with a docking slot 9 corresponding to the fuse 8. The docking slot 9 is provided with two sets of springs 10 that cooperate with the fuse 8. When the fuse 8 is inserted into the docking slot 9, the springs 10 will make tight contact with the fuse 8 to ensure a good electrical connection.

[0039] Auxiliary clamping assembly: Four sets of clamping plates 12 corresponding to the fuse 8 are slidably connected on the mounting bracket 5. Clamping springs 13 and retractable sealing strips are provided between the four sets of clamping plates 12 and the mounting bracket 5. The inner surface of the clamping plates 12 is provided with anti-slip texture. The clamping springs 13 are high temperature resistant springs. The retractable sealing strips are made of fireproof material.

[0040] Maintenance door: The main body of the power distribution cabinet 1 is equipped with a maintenance door 14 corresponding to the first fixed frame 2 and the second fixed frame 3, which facilitates the maintenance and repair of internal components. A transparent plate 15 is provided in the center of the maintenance door 14, which allows the operator to observe the internal situation without opening the maintenance door.

[0041] Workflow

[0042] Position adjustment of the first and second fixed frames: In the initial stage of device installation, the distance between the first fixed frame 2 and the second fixed frame 3 can be adjusted by adjusting the telescopic rod 11 in the assembly according to actual needs. When it is necessary to increase the distance between the first fixed frame 2 and the second fixed frame 3, the telescopic rod 11 is extended to push the second fixed frame 3 away from the first fixed frame 2; conversely, when it is necessary to reduce the distance, the telescopic rod 11 is shortened to pull the second fixed frame 3 closer to the first fixed frame 2.

[0043] Because the surfaces of the first fixing frame 2 and the second fixing frame 3 have insulating coatings, electrical short circuits can be effectively avoided during operation.

[0044] Fuse insertion: Insert fuse 8 into the mating slot 9 on the mounting bracket 5. The two sets of springs 10 in the mating slot 9 will automatically fit against the surface of fuse 8 to ensure electrical connection. During the insertion of fuse 8, the four sets of clamping plates 12 will slide outward due to the compression of fuse 8. At this time, the clamping spring 13 is compressed. When fuse 8 reaches the appropriate position, the elastic force of clamping spring 13 will push clamping plate 12 to move inward. The anti-slip texture of clamping plate 12 will increase the friction with fuse 8. At the same time, the retractable sealing strip will play a sealing and auxiliary fixing role between clamping plate 12 and fuse 8. Since clamping spring 13 is a high temperature resistant spring, it can ensure sufficient clamping force even when the distribution cabinet generates high temperature during operation. The fireproof material properties of the retractable sealing strip give it a certain fireproof isolation function in the event of a potential electrical fire.

[0045] Observation through the maintenance door: During daily use, operators can observe the working status of components such as the first fixed frame 2, the second fixed frame 3, and the fuse 8 inside the distribution cabinet through the transparent panel 15 at the center of the maintenance door 14. For example, they can observe whether the fuse 8 is blown or whether the connection is loose. There is no need to open the maintenance door 14, thus avoiding the operational risks caused by frequently opening the maintenance door 14.

[0046] Maintenance operations: When it is necessary to maintain internal components or replace fuse 8, open maintenance door 14 and adjust the distance between first fixed frame 2 and second fixed frame 3 by adjusting telescopic rod 11 to make the operating space more spacious. When replacing fuse 8, first fixed frame 2 and second fixed frame 3 separate, so that connecting plate 6 separates from slot 7. Mounting bracket 5 is not energized at this time, and fuse 8 can be installed and replaced. After replacement, second fixed frame 3 is reset, connecting plate 6 is inserted into slot 7, and fuse 8 continues to operate normally.

[0047] When replacing fuse 8, simply overcome the spring force of clamping spring 13, remove the old fuse 8 from the mating groove 9, and then insert the new fuse 8. Clamping plate 12 and clamping spring 13 will automatically complete the clamping and fixing operation of the new fuse 8.

[0048] The automatic power-off protection device for temperature monitoring of the distribution cabinet in this embodiment achieves flexible structural adjustment, stable fuse fixing, good protection performance, and convenient maintenance operation through the coordinated work of various components. The adjustment component can flexibly adjust the relative position of the first fixing frame 2 and the second fixing frame 3, and the auxiliary clamping component ensures the stable installation and reliable connection of the fuse 8. The maintenance door 14 and its transparent plate 15 facilitate daily observation and maintenance operations. At the same time, the detailed design of insulating coating, high-temperature resistant spring, fireproof materials, etc., further improves the safety and reliability of the device and meets the various needs of the distribution cabinet in actual use.

[0049] The above description is only for illustrating the present utility model. It should be understood that the present utility model is not limited to the above embodiments, and various modifications that conform to the concept of the present utility model are within the protection scope of the present utility model.
