Description

Technical Field

[0001] This utility model relates to the field of frame circuit breaker technology, and in particular to an insulating partition plate for a low-voltage cabinet frame circuit breaker that is easy to install and disassemble. Background Technology

[0002] Low-voltage distribution cabinets are products used for converting and configuring electrical energy. They are used in power distribution systems with a rated current of 50Hz AC and a rated voltage of 380V for power, lighting, and distribution energy conversion and control. These products feature strong breaking capacity, good dynamic and thermal stability, flexible electrical schemes, convenient combination, strong series compatibility and practicality, and novel structure. Generally, low-voltage distribution cabinets are equipped with frame circuit breakers.

[0003] A frame circuit breaker is a common type of circuit breaker structure. It is a mechanical switching device capable of connecting, carrying, and disconnecting current under normal circuit conditions, as well as connecting, carrying, and disconnecting current for a specified time under specified abnormal circuit conditions. It is an important electrical device in the power grid. Without insulating separators, the terminals of a frame circuit breaker are exposed. If a metal object accidentally touches the terminals, or if there is phase-to-phase arcing, it may cause a short circuit. Insulating separators effectively prevent this from happening, ensuring the safe operation of the circuit. Insulating separators also effectively prevent arc flash, protecting electrical equipment and personnel safety. Arc flash can cause equipment damage or fire; therefore, arc-damping plates play a crucial role in ensuring electrical safety.

[0004] However, existing insulating partitions have the following drawbacks in practical use:

[0005] Existing insulating partitions are typically installed by inserting the partitions into slots between two inlet and outlet ports, and then securing them one by one with multiple screws. This method is cumbersome, and because the space inside the low-voltage cabinet is small, it is inconvenient for workers to insert the screws into the screw holes. Utility Model Content

The number of snap-fit ​​blocks 10 and sliding posts 11 corresponds to the number of receiving cavities 9. There are two pressing blocks 15, each located between one of the four sliding posts 11. Two circular... The corner surface and one end of the sliding column 11 are both provided with arc surfaces. The rounded corner surface of the pressing block 15 matches the arc surface of one end of the sliding column 11. The sliding column 11 is fixedly installed on one side of the snap-fit ​​block 10. A sliding groove 18 is provided in the snap-fit ​​block 10. A sliding rod 13 is slidably installed in the sliding groove 18. The pressing block 15 is fixedly installed on the periphery of the sliding rod 13. The pressing block 15 corresponds to the sliding column 11. A first spring 17 is provided between the sliding rod 13 and one side of the inner wall of the sliding groove 18. An extension slot 19 is provided on one side of the snap-fit ​​plate 8. The snap-fit ​​block 10 is located in the extension slot 19. The sliding groove 18 A fixed post 16 is fixedly installed on one side of the inner wall. One end of the sliding rod 13 is slidably connected to the fixed post 16. A first spring 17 is sleeved around the fixed post 16. A button 14 is provided at one end of the sliding rod 13. The button 14 is slidably installed at one end of the snap-fit ​​plate 8. A second spring 12 is provided between the snap-fit ​​block 10 and one side of the inner wall of the storage cavity 9. The second spring 12 is sleeved around the sliding post 11. The lower end of the circuit breaker 1 is provided with an inlet 2, and the upper end of the circuit breaker 1 is provided with an outlet 3. A snap-fit ​​groove 24 is opened in the middle of the inlet 2 and the outlet 3. The main partition 5 is connected by the snap-fit ​​plate 8 and the snap-fit ​​groove 24. Connected to inlet 2 and outlet 3, there are several inlet 2 and outlet 3, and several snap-fit ​​slots 24. The number of insulating partitions 4 corresponds to the number of snap-fit ​​slots 24. The snap-fit ​​slots 24 are opened between two adjacent inlet 2 and two adjacent outlet 3. The insulating partitions 4 are set between two adjacent inlet 2 and two adjacent outlet 3 through snap-fit ​​plates 8 and snap-fit ​​slots 24. Two arc-shaped grooves are opened on both sides of the inner wall of the snap-fit ​​slot 24. The snap-fit ​​block 10 is snapped into the arc-shaped groove. One end of the snap-fit ​​slot 24 has a chamfered surface facing both sides.

[0027] Reference Figure 2 and Figure 4As shown, the insulating partition 4 includes a main partition 5, an extension partition 6, and a plug-in plate 20. The main partition 5 is fixedly installed on one side of the snap-fit ​​plate 8. Both the main partition 5 and the extension partition 6 have slots at one end. The plug-in plate 20 is fixedly installed on the other end of the extension partition 6 and is inserted into the slot. The inner walls of the slots have slots on both sides. The plug-in plate 20 has mounting slots 21 on both sides. A retaining bead 23 is slidably installed in the mounting slot 21. A third spring 22 is provided between the retaining bead 23 and one side of the inner wall of the mounting slot 21. The retaining bead 23 is movably engaged in the slot. The extension partition 6 is used to increase the partition length of the insulating partition according to different terminal lengths, so that the insulating partition can be used for terminals of different lengths, improving the practicality and applicability of the insulating partition.

[0028] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview:

[0029] In use, when installing the main partition 5, pressing the button 14 causes the sliding rod 13 to move along the sliding groove 18 and the fixed post 16. The movement of the sliding rod 13 can move the two pressing blocks 15, causing the pressing blocks 15 to be misaligned with the sliding post 11, stopping the pressing and limiting of the sliding post 11. Then, by inserting the snap-fit ​​plate 8 into the snap-fit ​​groove 24, when the snap-fit ​​block 10 contacts the inner wall of the snap-fit ​​groove 24, the arc shape of the snap-fit ​​block 10 and the chamfered surface at one end of the insertion opening of the snap-fit ​​groove 24 cause the snap-fit ​​block 10 to retract into the storage cavity 9 under the pressure. When the four snap-fit ​​blocks 10 move to correspond to the four arc-shaped grooves, the snap-fit ​​blocks 10 can extend out of the groove opening 19 and insert into the arc-shaped groove by the elastic force of the second spring 12. Releasing button 14 allows sliding rod 13 to reset and move due to the elastic force of first spring 17. Pulling button 14 can also reset sliding rod 13. The movement of sliding rod 13 can drive pressing block 15 to move. Pressing block 15 abuts against one end of sliding post 11, preventing sliding rod 13 from moving. This limits and fixes sliding rod 13 and locking block 10, allowing locking block 10 to be stably inserted into the arc-shaped groove, improving the stability of main partition 5 after installation. When disassembling main partition 5, repeat the above steps and pull main partition 5 outward to remove it. This allows workers to easily and quickly install and disassemble main partition 5, improving the practicality and convenience of using the insulating partition.

[0030] When the length of the terminal is longer than that of the main partition 5, the plug plate 20 on the upper side of an extension partition 6 is inserted into the slot on the lower side of the main partition 5. When the plug plate 20 is inserted into the slot, the retaining bead 23 is compressed and can retract into the mounting groove 21. When the retaining bead 23 moves to correspond with the retaining groove on the inner wall of the slot, the retaining bead 23 can be inserted into the retaining groove, so that the extension partition 6 is connected to the main partition 5. Furthermore, the slot on the lower side of the extension partition 6 allows the operator to increase the separation length of the insulating partition according to different terminal lengths.

[0031] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings.
