Description

Technical Field

[0001] The present invention belongs to the technical field of distribution boxes, and in particular relates to an intelligent distribution cabinet. Background Art

[0002] As the terminal equipment of the intelligent power distribution system, which is crucial in modern power systems, the intelligent power distribution cabinet plays a key role in ensuring the stable supply and efficient distribution of electricity. Specifically, the switchgear, as the key control component of the power distribution system, can realize the on-off operation of the circuit, ensuring the safety and reliability of power transmission; it can monitor key electrical parameters such as voltage, current, and power in real time, providing accurate data support for operators to timely understand the operating status of the system; when the circuit fails, such as overload or short circuit, the protective electrical equipment can act quickly to cut off the faulty circuit, prevent the fault from expanding, and protect the safety of electrical equipment and personnel; with advanced intelligent management equipment and related programs, the intelligent power distribution cabinet not only has the basic functions of the traditional power distribution cabinet, but also realizes intelligent features such as remote monitoring, fault diagnosis, and automatic control. It can automatically adjust the operating parameters according to the actual power demand and optimize the power distribution, greatly improving the automation level and operating efficiency of the power system.

[0003] During the assembly of smart distribution cabinets, connecting wires are required to connect and fix electrical components. Currently, screws are commonly used for installation and fixation. However, this method has many drawbacks in practical applications: First, due to the limited installation location and internal space, workers face many inconveniences when performing screw tightening and assembly operations. During subsequent maintenance work, the screw removal operation is also difficult. Furthermore, when fastening with screws, frequent turning of the screws during installation or maintenance can scratch the screw surface, damaging the screw's passivation film (such as the chromium oxide layer on stainless steel), causing the screw to lose its rust-resistant properties. Subsequently, during operation, the intelligent distribution cabinet can allow moisture to enter through gaps due to factors such as the "electrical breathing effect" and poorly sealed cable entry and exit ports. Increased humidity inside the cabinet can easily cause corrosion of metal components such as screws, which further reduces the mechanical strength of these components. Furthermore, corrosion can increase the contact resistance between the screws and the connector, ultimately leading to localized heating and even short circuit failures. Summary of the Invention

It is a relatively mature technology and will not be described in detail here. A mounting guide plate 16 is provided inside the distribution cabinet main body 11, and a mounting slot 13 for engaging with the mounting guide plate 16 is provided at the rear end of the electrical component main body 17. For the mounting guide plate 16, the number can be one, two or three groups, etc. The number of corresponding electrical component main bodies 17 is selected and set according to actual needs, and it does not affect normal operation. It is a relatively mature technology and will not be described in detail here. A fixing plate 18 is also provided inside the distribution cabinet main body 11. The electrical component main body 17 is electrically connected to a connecting wire 19 through a plug-in mechanism. A clamping mechanism for positioning and fixing the connecting wire 19 is provided on the fixing plate 18, which can conveniently fix the connecting wire 19 electrically connected to the electrical component main body 17 to ensure stability and firmness, and also facilitate subsequent disassembly, maintenance or replacement operations.

[0031] See also Figure 1-Figure 7In order not to affect the wiring of the distribution box body, and at the same time ensure the sealing effect of the wire inlet hole 15 and the wire outlet hole 14, prevent external moisture from entering the interior of the distribution cabinet body 11 through the wire inlet hole 15 and the wire outlet hole 14, and ensure the internal dryness and cleanliness, the distribution cabinet body 11 is provided with a wire outlet hole 14 and a wire inlet hole 15. The positions of the wire outlet hole 14 and the wire inlet hole 15 can be opened according to the convenience of actual wiring, and can be opened at the top, bottom or side wall. In this embodiment, it is preferably opened at the bottom of the distribution cabinet body 11.

The sealing component structure in the inlet hole 15 is the same as the sealing component structure in the outlet hole 14, and the aperture of the elastic guide ring 31 in the inlet hole 15 gradually increases from the distribution cabinet body 11 to the outside. The air cavity 32 inside the elastic guide ring 31 is filled with gas, and the sealing ring 33 is used to seal the routing wires. When the wires are energized, heat is generated, and the heat is transferred to the air cavity 32. The internal gas expands due to the heat to ensure the sealing effect.

[0032] See also Figure 1-Figure 7In order to facilitate the connection between the electrical component body 17 and the connecting wire 19, the operation can be completed without the aid of tools. The electrical component body 17 and the connecting wire 19 are electrically connected through a plug-in mechanism. The plug-in mechanism includes a mounting hole 27 provided on the electrical component body 17. The mounting hole 27 is provided at the bottom of the electrical component body 17, or at the top, so as to facilitate plug-in connection with the connecting wire 19. It can also be provided on the side according to actual conditions. A conductive member 21 is provided in the mounting hole 27. The material of the conductive member 21 can be copper or other metals with good conductive effects. A plug-in slot 26 is provided inside the conductive member 21. A connecting lead 22 is provided at the end of the connecting wire 19. The material of the connecting lead 22 is consistent with the material of the conductive member 21. Similarly, the connecting lead 22 is inserted into the plug-in slot 26 and electrically connected to the conductive member 21. Positioning slots 23 are symmetrically provided on the side surfaces of the connecting lead 22, and empty slots 24 are symmetrically provided on the side surfaces of the conductive member 21. An elastic conductive block 25 matching the positioning slot 23 is provided in the empty slot 24. The elastic conductive block 25 is made of the same material as the conductive member 21 and can be integrally formed. The two ends of the positioning slot 23 are in the shape of an inclined slope 28 with the connecting lead 22, which is used to reduce the resistance between the elastic conductive block 25 and the positioning slot 23 when the connecting lead 22 rotates axially, facilitate the axial rotation of the connecting lead 22, and then separate the elastic conductive block 25 from the positioning slot 23, and then conveniently remove the connecting lead 22 from the plug-in slot 26 to complete the disassembly, which is convenient for maintenance or replacement operations.

[0033] See also Figure 1-Figure 7 In order to position and fix the connecting wire 19 after it is plugged in, a clamping mechanism is provided on the fixing plate 18 for convenient clamping and fixing the connecting wire 19. The number of clamping mechanisms corresponds to the number of connecting wires 19, which is convenient for clamping and fixing them separately. The clamping mechanism is a mounting plate 41 arranged on the side wall of the fixing plate 18. First memory alloys 43 are symmetrically arranged in the mounting plate 41. An elastic pad 42 is provided between the first memory alloy 43 and the mounting plate 41. The first memory alloy 43 is used to clamp and fix the connecting wire 19. When the connecting wire 19 is energized and heated, the first memory alloy 43 has a tendency to recover and shrink. During the process of energizing the connecting wire 19, the connecting wire 19 will heat up due to the Joule effect of resistance loss, and the temperature rises. At this time, the first memory alloy 43 is transformed from the martensite phase to the austenite phase after being heated, and automatically restores its initial shape. The two first memory alloys 43 approach each other and shrink, clamping and fixing the connecting wire 19.

[0034] Example 2 See also Figure 8 and Figure 9As for the clamping mechanism, the clamping mechanism is a mounting plate 41 arranged on the side wall of the fixing plate 18, and a first air-filled bag 51 is symmetrically arranged in the mounting plate 41, and an elastic pad 42 is arranged between the first air-filled bag 51 and the mounting plate 41. An air-filled chamber 52 is opened inside the first air-filled bag 51, and a first clamping pad 53 is provided on the inner arc surface of the first air-filled bag 51, which is used to clamp and fix the connecting wire 19. When the connecting wire 19 is energized and heated, the first air-filled bag 51 tends to expand due to heat. The first memory alloy 43 is replaced by the first air-filled bag 51, and an air-filled chamber 52 is opened inside. When the connecting wire 19 is energized, the connecting wire 19 will heat up due to the Joule effect of resistance loss. When the temperature rises, the gas inside the air-filled chamber 52 expands due to the heat, and cooperates with the first clamping pad 53 to clamp and fix the connecting wire 19.

[0035] Example 3 See also Figure 10 As for the clamping mechanism, the clamping mechanism is a mounting plate 41 arranged on the side wall of the fixing plate 18, and a second memory alloy 61 is symmetrically arranged in the mounting plate 41. An elastic pad 42 is arranged between the second memory alloy 61 and the mounting plate 41. The second memory alloy 61 is used to clamp and fix the connecting wire 19. When the connecting wire 19 is energized and heated, the second memory alloy 61 tends to recover and shrink. The length of the second memory alloy 61 along the connecting wire 19 is greater than the length of the mounting plate 41. The difference between the second memory alloy 61 and the first alloy is that the second memory alloy 61 is longer along the connecting wire 19, which increases the contact area with the connecting wire 19 and improves the clamping effect.

[0036] Example 4 See also Figure 11 As for the clamping mechanism, the clamping mechanism is a mounting plate 41 arranged on the side wall of the fixing plate 18, and a third memory alloy 71 is symmetrically arranged in the mounting plate 41, and an elastic pad 42 is arranged between the third memory alloy 71 and the mounting plate 41, and a second air-filled bag 72 is provided on the upper and lower end surfaces of the third memory alloy 71, and a second clamping pad 73 is provided in the second air-filled bag 72. The third memory alloy 71 is the same as the first memory alloy 43, and a second air-filled bag 72 is provided on the upper and lower end surfaces of the third memory alloy 71, and the second air-filled bag 72 is filled with gas. The third memory alloy 71 and the second air-filled bag 72 are used to clamp and fix the connecting wire 19. When the connecting wire 19 is energized and heated, the second memory alloy 61 tends to recover and shrink, and the second air-filled bag 72 tends to expand. The two assist in cooperation to ensure the clamping and fixing effect of the connecting wire 19.

[0037] When in use, the electrical component body 17 is installed and fixed by installing the guide plate 16 and the mounting slot 13. When wiring, the wire is inserted through the wire entry hole 15, and when outgoing, the wire exit hole 14 is passed through, and both are preliminarily sealed and positioned in cooperation with the elastic guide ring 31 and the sealing ring 33. When the electrical component body 17 is electrically connected to the electrical component body 17 through the connecting wire 19, the connecting lead 22 is inserted into the connecting lead 22 of the conductive member 21. During the insertion process, an extrusion force is generated on the elastic conductive block 25 away from each other, and the elastic conductive block 25 rotates in the empty slot 24. When the connecting lead 22 is inserted, the elastic conductive block 25 is aligned with the positioning slot 23. Under the action of the elastic potential energy of the elastic conductive block 25, it resets and rotates. The elastic conductive block 25 is engaged with the positioning slot 23 to complete the limit, and the connecting lead 22 on the connecting wire 19 is preliminarily positioned and fixed. When clamping the connecting wire 19, the connecting wire 19 is pushed between the two mounting plates 41 of the fixing plate 18. At this time, the clamping assembly is based on Example 1. For example, an extrusion force is generated on the first memory alloys 43 to move them away from each other, and the elastic pad 42 contracts under the force to store potential energy. After being pushed in, it is reset under the action of the potential energy of the elastic pad 42, and is initially clamped and fixed by the first memory alloy 43. When the connecting wire 19 is energized, the connecting wire 19 will heat up due to the Joule effect of resistance loss, and the temperature will rise. At this time, the first memory alloy 43 will transform from the martensite phase to the austenite phase after being heated, and automatically restore its initial shape. The two first memory alloys 43 will move closer to each other and contract, clamping and fixing the connecting wire 19. When the connecting wire 19 needs to be disassembled, after power is turned off, the connecting wire 19 can be removed from the clamping mechanism, and then the connecting wire 19 can be rotated axially, and the connecting lead 22 can be rotated with it. At this time, the elastic conductive block 25 is separated from the positioning groove 23 in conjunction with the inclined slope 28 of the positioning groove 23, and the limiting fixation of the connecting lead 22 is lost. The connecting lead 22 can be removed from the plug slot 26 of the conductive member 21, completing the disassembly, which is convenient for subsequent maintenance or replacement.
