Description

Technical Field

[0001] The present invention belongs to the technical field of power distribution cabinets, and in particular to an intelligent power distribution cabinet and a method for using the same. Background Art

[0002] With the increasing demand for intelligent and automated power systems, intelligent distribution cabinets (SDCs), a new generation of power distribution devices integrating modern information technology, automated control, and power equipment management technologies, are becoming a core component of power distribution and management. Through built-in sensors, controllers, and communication modules, they can monitor power parameters such as current, voltage, and power in real time, enabling remote monitoring, data collection, fault diagnosis, and automatic control. Compared to traditional distribution cabinets, they significantly improve the reliability, safety, and management efficiency of power systems and are widely used in industrial production, commercial buildings, information technology rooms, and other scenarios.

[0003] However, in some specialized application scenarios, such as railway hubs, mining operations, road and bridge construction, and heavy machinery manufacturing workshops, smart power distribution cabinets face the severe test of strong vibration. In these scenarios, factors such as the high-frequency operation of mechanical equipment and frequent vehicle traffic generate continuous and strong vibrations, causing the power distribution cabinet to operate in a dynamically unstable environment.

[0004] Prolonged exposure to high vibration can severely impact the internal structure and electrical connections of intelligent power distribution cabinets. The stability of the connecting wires and terminals is particularly affected. Although the wires are securely connected during initial installation, continued vibration can cause them to loosen due to repeated stress, eventually falling off and detaching from the terminals. If a loose wire accidentally comes into contact with other components or wiring within the distribution cabinet, it can easily create a short circuit. This short circuit can easily cause a fire, disrupting power supply and damaging equipment, potentially endangering human life and causing immeasurable economic losses and social impact.

[0030] Step 1: Install the power distribution cabinet in a suitable location and complete the wiring of the main circuit (power input, load output) and the secondary circuit (sensor, communication module);

[0031] Step 2: Set the basic parameters of the power distribution cabinet and the delay time of the protection function; add the intelligent power distribution cabinet device in the remote monitoring platform or management software, configure the communication protocol, IP address, port number and other parameters, and ensure that the device is successfully connected to the platform;

[0035] The beneficial effects of the present invention are as follows:

[0036] 1. The intelligent power distribution cabinet and its use method described in the present invention, since the annular member is made of insulating rubber material and has a certain elasticity, it can fill the gap between the head of the locking bolt and the component, and generate continuous friction through elastic deformation, thereby increasing the tightening effect of the locking bolt, avoiding the self-loosening of the locking bolt due to periodic vibration, causing the wire to detach from the terminal, and preventing the vibrated wire from accidentally contacting other components or wires in the power distribution cabinet, causing a short circuit and fire.

[0037] 2. The intelligent power distribution cabinet and the method of using the same described in the present invention, due to the spring between the insulating cylinder and the insulating rubber plug, under the action of elastic force, the insulating cylinder partially slides out of the wire management groove and fits with the surface of the component. If the power distribution cabinet is subjected to long-term vibration, causing the locking bolt to loosen and no longer clamp the wires inside the terminal, the wires connected to the terminal are clamped in the arc-shaped spring piece, and the insulating cylinder fits with the surface of the component under the elastic force of the spring, so the wires can be limited and supported so that the wires remain in the terminal, avoiding the wires from detaching from the terminal and accidentally contacting other components or wires inside the distribution cabinet, causing a short circuit and fire.

[0038] 3. The intelligent power distribution cabinet and its use method described in the present invention, if the power distribution cabinet is subjected to long-term vibration, which causes the locking bolt to be detached, the wires will be detached from the terminal because they are no longer fixed by the locking bolts. At the same time, because the ring and the ring part are no longer fixed by the locking bolts, the tension of the tension spring will pull the insulating cylinder into the wire management trough, and at the same time drive the ring and the ring part to move. Since the wires are clamped by the arc-shaped spring pieces, the moving insulating cylinder will use the arc-shaped spring pieces to pull the wires gradually into the wire management trough. The wire management trough can block the fallen wires, thereby preventing the fallen wires from contacting other components or wires, causing short circuits and fires. At the same time, since the wire management board and the insulating cylinder are both flame retardant, burning of the insulating cylinder and the wire management board can be avoided.

[0039] 4. The intelligent power distribution cabinet and the use method thereof described in the present invention have a pin shaft inserted on the circular ring, which can block the locking bolt located in the circular ring and prevent the locking bolt from gradually separating from the component, thereby further improving the locking effect of the locking bolt. Since a hemisphere is provided on the L-shaped plate, when the L-shaped plate is hung on the U-shaped clamp, the hemisphere will be stuck in the hemisphere groove, and since the L-shaped plate bears the tension of the insulating tube, the L-shaped plate and the U-shaped clamp can be made to fit more tightly, thereby improving the fixing effect between the L-shaped plate and the U-shaped clamp. When the fixing effect between the L-shaped plate and the U-shaped clamp is improved, since the pin shaft is inserted on the circular ring, the blocking effect of the pin shaft on the locking bolt is also improved. Therefore, the ability of the pin shaft to withstand the thrust generated when the locking bolt is loosened can be effectively improved, thereby further improving the fixing effect of the locking bolt.

[0051] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0052] As an embodiment of the present invention; Figures 1 to 9 As shown, on the one hand, the present invention discloses an intelligent power distribution cabinet, comprising a power distribution cabinet; a cabinet door is installed on the power distribution cabinet; a power distribution unit, an intelligent monitoring unit, an intelligent control unit and a communication module are arranged in the power distribution cabinet;

[0053] A plurality of guide rails 1 are fixedly installed in the power distribution cabinet; components 11 are evenly arranged and installed on the guide rails 1, and the components 11 are circuit breakers; the components 11 do not contact the back panel of the power distribution cabinet; the components 11 are provided with terminal blocks 111 and locking bolts 112, and the locking bolts 112 are threadedly engaged with the thread grooves on the components 11;

[0054] Each guide rail 1 is provided with a wire management plate 2 on both sides, and the wire management plate 2 is made of flame retardant material, and the wire management plate 2 is installed in the power distribution cabinet; the two wire management plates 2 on the upper and lower sides of the guide rail 1 have the same structure and are mirror-imaged;

[0055] The wire management plate 2 is provided with a plurality of evenly arranged wire management slots 21; the wire management slots 21 correspond to the connection terminals 111 on the components 11;

[0056] The ends of the cable management grooves 21 away from the guide rails 1 are fixedly connected to two insulating rubber plugs 22, and the insulating rubber plugs 22 are semicircular and arranged opposite to each other;

[0057] An insulating tube 23 is slidably connected to each of the cable management slots 21, and the insulating tube 23 is made of insulating flame-retardant material; two arc-shaped spring pieces 24 are arranged opposite to each other at one end of the insulating tube 23 close to the component 11; the surface of the arc-shaped spring piece 24 is covered with an insulating rubber layer;

[0058] The end of the insulating tube 23 close to the component 11 is fixedly connected to the insulating rubber belt 25; the insulating rubber belt 25 is fixedly connected to the ring 3;

[0059] The wire 12 connected to the terminal 111 of the component 11 first passes between the two arc-shaped springs 24, then passes between the two insulating rubber plugs 22 in the wire management groove 21, and extends downward;

[0060] A ring member 31 is provided on the side of the ring 3 close to the component 11, and the ring member 31 is fixedly connected to the ring 3, and the ring member 31 is made of insulating rubber material; the locking bolt 112 passes through the ring 3 and the ring member 31 and is locked on the component 11;

[0061] In this embodiment, a spring is provided between the insulating cylinder 23 and the insulating rubber plug 22, and the insulating cylinder 23 partially slides out of the cable management groove 21 under the elastic force of the spring and fits against the surface of the component 11;

[0062] In this embodiment, a tension spring is provided between the insulating cylinder 23 and the insulating rubber plug 22 , and the insulating cylinder 23 is completely located in the cable management groove 21 under the tension of the tension spring, with a certain distance between the insulating cylinder 23 and the component 11 .

[0063] During installation, first install the distribution cabinet in a suitable position and connect the components 11 in the distribution cabinet. Since the component 11 is provided with a mirror-imaged wire management plate 2 on the upper and lower sides, when wiring the terminal 111 in the component 11, it is necessary to pass through the wire management groove 21, and at the same time, pass the wire 12 through the insulating cylinder 23. Then, when connecting to the terminal 111 of the component 11, when the wire 12 passes through the insulating cylinder 23, the wire 12 passes through the two arc-shaped spring pieces 24. When the wire 12 passes through the wire management groove 21, the wire 12 passes through the two insulating rubber plugs 22. When the wire 12 is connected to the terminal 111, the wire 12 is clamped in the insulating rubber plug 22 and the arc-shaped spring piece 24 respectively. Since the surface of the arc-shaped spring piece 24 is covered with a rubber layer, electrical conduction can be avoided from now on.

[0064] When the locking bolt 112 is used to lock the wire 12 inserted into the terminal 111, the ring 3 is pulled close to the locking bolt 112. The ring 3 will pull the insulating tube 23 gradually close to the component 11 through the insulating rubber belt 25. When the ring 3 moves to the threaded groove position on the component 11, the insulating tube 23 is fitted with the component 11, and the terminal 111 is located in the inner circle of the insulating tube 23. Then, the wire 12 connected to the terminal 111 is straightened, and then the locking bolt 112 is passed through the ring 3 and the ring part 31, and the locking bolt 112 is screwed into the component 11, and the wire 12 in the terminal 111 is locked. When the locking bolt 112 is locked, the locking bolt 112 will press the ring part 3 1 fits with the component 11, and the bolt head of the locking bolt 112 will be located in the ring 3, thereby locking and fixing the ring 31 and the ring 3. Since the ring 31 is made of insulating rubber material and has a certain elasticity, it can fill the gap between the head of the locking bolt 112 and the component 11, and generate continuous friction through elastic deformation, thereby increasing the tightening effect of the locking bolt 112, avoiding the self-loosening of the locking bolt 112 due to periodic vibration, causing the wire 12 to be separated from the terminal 111, and avoiding the accidental contact of the vibrated wire 12 with other components 11 or wires 12 in the distribution cabinet, resulting in a short circuit and fire. When all components 11 are connected, the distribution cabinet can be put into use after debugging.

[0065] As an implementation method of this embodiment, due to the spring between the insulating tube 23 and the insulating rubber plug 22, under the action of elastic force, the insulating tube 23 partially slides out of the wire management groove 21 and fits with the surface of the component 11. If the distribution cabinet is subjected to long-term vibration, the locking bolt 112 becomes loose and no longer clamps the wire 12 inside the terminal 111. Since the wire 12 connected to the terminal 111 is clamped in the arc-shaped spring piece 24, and the insulating tube 23 fits with the surface of the component 11 under the elastic force of the spring, the wire 12 can be limited and supported, so that the wire 12 remains in the terminal 111, avoiding the wire 12 from detaching from the terminal 111 and accidentally contacting other components 11 or wires 12 inside the distribution cabinet, causing a short circuit and fire.

[0066] As another implementation method in this embodiment, due to the tension spring between the insulating cylinder 23 and the insulating rubber plug 22, the insulating cylinder 23 is completely located in the wire management groove 21 under the action of tension. When wiring, the ring 3 is pulled close to the locking bolt 112, and then the locking bolt 112 is passed through the ring 3 and the ring part 31 to lock and fix the ring 3 and the ring part 31. When the ring part 31 and the ring 3 are fixed, the insulating cylinder 23 is in contact with the surface of the component 11, and the tension spring is in a stretched state. If the distribution cabinet is subjected to long-term vibration, causing the locking bolt 112 to be detached, the wire 12 will be detached from the terminal 1 because it is no longer fixed by the locking bolt 112. 11, and since the ring 3 and the ring part 31 are no longer fixed by the locking bolt 112, the tension of the tension spring will pull the insulating tube 23 into the cable management groove 21, and at the same time drive the ring 3 and the ring part 31 to move. Since the wire 12 is clamped by the arc-shaped spring piece 24, the moving insulating tube 23 will use the arc-shaped spring piece 24 to pull the wire 12 gradually into the cable management groove 21. The cable management groove 21 can block the fallen wire 12, thereby preventing the fallen wire 12 from contacting other components 11 or wires 12, causing a short circuit and fire. At the same time, since the cable management board 2 and the insulating tube 23 are flame retardant, the burning of the insulating tube 23 and the cable management board 2 can be avoided.

[0067] As an embodiment of the present invention; a U-shaped clamp 4 is provided on the periphery of the component 11, and the U-shaped clamp 4 is used to further fix the component 11;

[0068] The U-shaped clamps 4 and the locking bolts 112 are arranged alternately, and the two U-shaped clamps 4 are located between two locking bolts 112 that are opposite to each other.

[0069] The U-shaped clamp 4 is mounted on the guide rail 1 by means of bolts, and the bolts pass through the guide rail 1 and are threadedly engaged with nuts;

[0070] In this embodiment, an L-shaped plate 41 is installed on the side of the circular ring 3 facing the U-shaped clamp 4; the L-shaped plate 41 is hung on the adjacent U-shaped clamp 4 and fits with the U-shaped clamp 4; when the L-shaped plate 41 is hung on the U-shaped clamp 4, the center of the circular ring 3 and the locking bolt 112 are on the same horizontal plane;

[0071] A hemispherical body 42 is fixedly connected to the end surface of the L-shaped plate 41 on the side where the U-shaped clamp 4 is in contact. A hemispherical groove 43 is formed on the end surface of the U-shaped clamp 4 on the side where the L-shaped plate 41 is in contact, and the hemispherical body 42 is located in the hemispherical groove 43.

[0072] In this embodiment, a pin hole is passed through the ring 3; a pin shaft 32 is inserted into the pin hole, and the pin shaft 32 is made of insulating material;

[0073] In this embodiment, the annular member 31 and the locking bolt 112 are interference fit;

[0074] As an implementation method of this embodiment, since the U-shaped clamp 4 is provided on the component 11, when the U-shaped clamp 4 is installed, the U-shaped clamp 4 is passed around the component 11, and a bolt is passed through the guide rail 1, and fixed on the other side of the guide rail 1 with a nut. In this way, the U-shaped clamp 4 can be used to fix the component 11, thereby preventing the component 11 from falling off due to long-term vibration.

[0075] During implementation, when the locking bolt 112 is used to lock and fix the ring 3 and the annular member 31, the L-shaped plate 41 is first hung on the U-shaped clamp 4. The U-shaped clamp 4 can pull the L-shaped plate 41 and the insulating tube 23, thereby offsetting the tension of the tension spring on the insulating tube 23. When the L-shaped plate 41 is hung on the U-shaped clamp 4, the center of the ring 3 and the locking bolt 112 are on the same horizontal plane. Then, the locking bolt 112 can be used to lock and fix the annular member 31 and the ring 3.

[0076] During the implementation process, since the ring 3 is provided with a pin shaft 32, the pin shaft 32 can block the locking bolt 112 located in the ring 3, preventing the locking bolt 112 from gradually separating from the component 11, thereby further improving the locking effect of the locking bolt 112. Since the L-shaped plate 41 is provided with a hemisphere 42, when the L-shaped plate 41 is hung on the U-shaped clamp 4, the hemisphere 42 will be stuck in the hemisphere groove 43, and since the L-shaped plate 41 bears the tension of the insulating tube 23, it can The L-shaped plate 41 and the U-shaped clamp 4 are made to fit more tightly, thereby improving the fixing effect between the L-shaped plate 41 and the U-shaped clamp 4. When the fixing effect between the L-shaped plate 41 and the U-shaped clamp 4 is improved, since the pin 32 is inserted into the ring 3, the blocking effect of the pin 32 on the locking bolt 112 is also improved. Therefore, the ability of the pin 32 to withstand the thrust generated when the locking bolt 112 is loosened can be effectively improved, further improving the fixing effect of the locking bolt 112.

[0077] During the implementation process, as the component 11 is used for a long time in a vibration environment, if the locking bolt 112 gradually detaches from the component 11, it will also drive the L-shaped plate 41 to gradually detach from the U-shaped clamp 4. When the locking bolt 112 is completely detached from the component 11, the L-shaped plate 41 is completely detached from the U-shaped clamp 4. Due to the interference fit between the annular part 31 and the locking bolt 112, when the locking bolt 112 is detached from the component 11, the locking bolt 112 will be restricted in the annular part 31, thereby preventing the locking bolt 112 from falling down and being lost and causing waste.

[0078] As an embodiment of the present invention; vertical air ducts 5 are provided on both sides of the guide rail 1 inside the power distribution cabinet, and both ends of the guide rail 1 and the cable management plate 2 are fixedly mounted on the air ducts 5 on both sides;

[0079] The two sides of the power distribution cabinet are provided with evenly arranged air inlet slots 51, and fans are installed in the air inlet slots 51; filters are provided in the air inlet slots 51; and air outlet slots are provided on the back of the power distribution cabinet.

[0080] An air cavity 26 is provided in the wiring board 2, and the air cavity 26 is connected to the air duct 5; a side of the air cavity 26 close to the component 11 is provided with evenly arranged inclined grooves 27;

[0081] In this embodiment, a through groove 231 is formed on one side of the insulating tube 23 close to the air cavity 26 ; a guide groove 28 is formed on one side of the air cavity 26 close to the through groove 231 , and the guide groove 28 is connected to the through groove 231 ;

[0082] The insulating tube 23 has a notch 232 formed on one side thereof close to the arc-shaped spring piece 24.

[0083] As an implementation method in this embodiment, during the operation of the distribution cabinet, the fan is controlled to operate, and the external gas can be drawn into the air duct 5 through the air inlet slot 51. The gas in the air duct 5 will enter the air cavity 26 and then be blown out through the inclined slot 27. The gas blown out through the inclined slot 27 will directly act on the component 11, thereby dissipating the heat of the component 11; and since the through slot 231 on the insulating cylinder 23 is connected with the guide slot 28, the gas in the air cavity 26 will enter the insulating cylinder 23 through the guide slot 28 and the through slot 231. The gas entering the insulating cylinder 23 will continue to flow, and the flowing gas will gradually dissipate heat to the terminal 111, and the flowing gas will flow out through the missing slot 232, and finally the gas will flow out through the air outlet slot, so that the gas in the distribution cabinet circulates to dissipate heat.

[0084] On the other hand, the present invention also provides a method for using an intelligent power distribution cabinet, which is applicable to the above-mentioned intelligent power distribution cabinet and includes the following steps:

[0085] Step 1: Install the power distribution cabinet in a suitable location and complete the wiring of the main circuit (power input, load output) and the secondary circuit (sensor, communication module);

[0086] Step 2: Set the basic parameters of the power distribution cabinet and the delay time of the protection function; add the intelligent power distribution cabinet device in the remote monitoring platform or management software, configure the communication protocol, IP address, port number and other parameters, and ensure that the device is successfully connected to the platform;

[0087] Step 3: The intelligent monitoring unit collects power parameters of each circuit in real time. After the collected data is initially processed by the edge computing unit, it is stored locally and transmitted to the remote monitoring platform in real time via a wired or wireless network.

[0088] Step 4: Log in to the remote monitoring platform through the computer management software or mobile phone APP to view the real-time power parameters, equipment operating status and environmental data of the distribution cabinet;

[0089] Step 5: Analyze the collected data. When power parameters are abnormal (such as current overload, voltage instability) or environmental parameters exceed the standard (such as high temperature, smoke detection), the local sound and light alarm is immediately triggered, and the alarm information is sent to the remote monitoring platform; the platform combines the fault type and historical data.
