Description

Technical Field

[0001] The present invention belongs to the technical field of distribution cabinets, and specifically relates to an intelligent distribution cabinet and its usage method. Background Art

[0002] With the continuous improvement of the requirements for the intelligence and automation of power systems, intelligent distribution cabinets, as a new generation of power distribution devices integrating modern information technology, automation control technology, and power equipment management technology, have gradually become the core equipment for power distribution and management. Through built-in sensors, controllers, and communication modules, it can real-time monitor power parameters such as current, voltage, and power, and achieve functions such as remote monitoring, data acquisition, fault diagnosis, and automatic control. Compared with traditional distribution cabinets, it significantly improves the reliability, safety, and management efficiency of power systems, and is widely used in industrial production, commercial buildings, information computer rooms, and other scenarios. However, in some special application scenarios, such as railway transportation hubs, mining, road and bridge construction, heavy machinery manufacturing workshops, and other environments, intelligent distribution cabinets face severe tests of strong vibration. In these scenarios, factors such as the high-frequency operation of mechanical equipment and the frequent driving of vehicles will generate continuous and strong vibrations, resulting in a dynamically unstable working environment for the distribution cabinet. Being in a strong vibration environment for a long time has a serious impact on the internal structure and electrical connections of intelligent distribution cabinets. Among them, the stability of the connection between the connecting wire and the terminal block is the first to bear the brunt. Although the wire is firmly fixed during the initial installation, with the continuous action of vibration, the wire will gradually loosen due to repeated stress, and finally vibrate off and disconnect from the terminal block. Once the vibrated-off wire accidentally contacts other components or wires inside the distribution cabinet, it is extremely easy to form a short-circuit loop; after the short circuit, it is easy to cause a fire, which not only causes the interruption of power supply and equipment damage, but also may endanger the lives of personnel, bringing immeasurable economic losses and social impacts.

[0012] A usage method of an intelligent power distribution cabinet, which is applicable to the above-mentioned intelligent power distribution cabinet, includes the following steps: Step 1: Install the power distribution cabinet at a suitable position, and complete the wiring of the main circuit (power input, load output) and the secondary circuit (sensors, communication modules); Step 2: Set the basic parameters of the power distribution cabinet and the delay time of the protection function; in the remote monitoring platform or management software, add the intelligent power distribution cabinet device, configure parameters such as communication protocol, IP address, port number, etc., to ensure successful connection between the device and the platform; Step 3: Real-time collect the power parameters of each circuit through the intelligent monitoring unit; after the collected data is preliminarily processed by the edge computing unit, it is stored locally on the one hand, and on the other hand, it is transmitted to the remote monitoring platform in real time through wired or wireless networks; Step 4: Log in to the remote monitoring platform through the computer terminal management software or mobile phone APP to view the real-time power parameters, device operation status and environmental data of the power distribution cabinet; Step 5: Analyze the collected data.

[0013] The beneficial effects of the present invention are as follows: 1. For an intelligent power distribution cabinet and its usage method according to 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, generate a continuous frictional force through elastic deformation, increase the fastening effect of the locking bolt, and avoid the self-loosening phenomenon of the locking bolt caused by periodic vibration, which may lead to the wire detaching from the terminal block. This can prevent the fallen wire from accidentally contacting other components or wires inside the power distribution cabinet, thus avoiding the situation of short-circuit fire.

[0014] 2. For an intelligent power distribution cabinet and its usage method according to the present invention, due to the spring between the insulating cylinder and the insulating rubber plug, under the action of elastic force, part of the insulating cylinder slides out of the wire management groove and fits on the surface of the component. If the power distribution cabinet undergoes long-term vibration, resulting in the loosening of the locking bolt and no longer clamping the wire inside the terminal block, since the wire inserted into the terminal block is clamped within the arc-shaped elastic piece and the insulating cylinder fits on the surface of the component under the elastic force of the spring, the wire can be limited and supported, keeping the wire still inside the terminal block, and preventing the wire from detaching from the terminal block and accidentally contacting other components or wires inside the power distribution cabinet, thus avoiding the situation of short-circuit fire.

[0015] 3. For an intelligent power distribution cabinet and its usage method according to the present invention, if the power distribution cabinet undergoes long-term vibration, resulting in the detachment of the locking bolt, since the wire is no longer fixed by the locking bolt, the wire will detach from the terminal block. At the same time, since the circular ring and the annular member are no longer fixed by the locking bolt, under the pulling force of the tension spring, it will pull the insulating cylinder into the wire management groove, and at the same time drive the circular ring and the annular member to move. Since the wire is clamped by the arc-shaped elastic piece, the moving insulating cylinder will use the arc-shaped elastic piece to gradually pull the wire into the wire management groove. The wire management groove can block the fallen wire, thus avoiding the fallen wire from contacting other components or wires, and preventing the occurrence of short-circuit fire. At the same time, since both the wire management board and the insulating cylinder have flame retardant properties, it can prevent the insulating cylinder and the wire management board from catching fire.

[0016] 4. For an intelligent power distribution cabinet and its usage method according to the present invention, since a pin shaft is inserted into the circular ring, the pin shaft can block the locking bolt located within the circular ring, preventing the locking bolt from gradually detaching from the component, thereby further improving the locking effect of the locking bolt. Since a hemispherical body is provided on the L-shaped plate, when the L-shaped plate is hung on the U-shaped clamp, the hemispherical body will be stuck in the hemispherical groove. Also, since the L-shaped plate bears the pulling force of the insulating cylinder, it can make the L-shaped plate fit more tightly with the U-shaped clamp, 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 into the circular ring, the blocking effect of the pin shaft on the locking bolt is also improved. Therefore, it can effectively enhance the bearing capacity of the pin shaft against the thrust generated when the locking bolt loosens, and further improve the fixing effect of the locking bolt.

Detailed Embodiments

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0021] As an embodiment of the present invention; as Figures 1 to 9 shown, on the one hand, the present invention discloses an intelligent power distribution cabinet, including 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; A plurality of guide rails 1 are fixedly installed in the power distribution cabinet; components 11 are evenly arranged on the guide rails 1, and the components 11 are circuit breakers; the components 11 do not contact the back plate of the power distribution cabinet; the components 11 are provided with terminal blocks 111 and locking bolts 112, and the locking bolts 112 are in threaded engagement with the threaded grooves on the components 11; Cable management plates 2 are provided on both the upper and lower sides of each guide rail 1, and the cable management plates 2 are made of flame-retardant materials and are installed in the power distribution cabinet; the two cable management plates 2 on the upper and lower sides of the guide rail 1 have the same structure and are arranged in a mirror image; A plurality of evenly arranged cable management grooves 21 are formed on the cable management plates 2; the cable management grooves 21 correspond to the terminal blocks 111 on the components 11; Two insulating rubber plugs 22 are fixedly connected to one end of each cable management groove 21 away from the guide rail 1, and the insulating rubber plugs 22 are semi-circular and are arranged oppositely; Insulating cylinders 23 are slidably connected in the cable management grooves 21, and the insulating cylinders 23 are made of insulating and flame-retardant materials; two oppositely arranged arc-shaped elastic pieces 24 are provided at one end of the insulating cylinder 23 close to the component 11; an insulating rubber layer is coated on the surface of the arc-shaped elastic piece 24; An insulating rubber band 25 is fixedly connected to one end of the insulating cylinder 23 close to the component 11; a circular ring 3 is fixedly connected to the insulating rubber band 25; The wire 12 connected to the terminal block 111 of the component 11 first passes between the two arc-shaped elastic pieces 24, then passes between the two insulating rubber plugs 22 in the cable management groove 21, and extends downward; An annular member 31 is provided on one side of the circular ring 3 close to the component 11, and the annular member 31 is fixedly connected inside the circular ring 3 and is made of insulating rubber material; the locking bolt 112 passes through the circular ring 3 and the annular member 31 and is locked on the component 11; In this embodiment, a spring is provided between the insulating cylinder 23 and the insulating rubber plug 22, and the insulating cylinder 23 slides out of the cable management groove 21 partially under the elastic force of the spring and fits on the surface of the component 11; 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 inside the cable management groove 21 under the pulling force of the tension spring, and there is a certain distance between the insulating cylinder 23 and the component 11.

[0022] During installation, first install the power distribution cabinet in a suitable position and wire the components 11 inside the power distribution cabinet. Since wire management boards 2 are provided on the upper and lower sides of the component 11 in a mirror image arrangement, during the wiring process of the wiring terminals 111 inside the component 11, it is necessary to pass through the wire management grooves 21. At the same time, pass the wire 12 through the insulating cylinder 23, and then connect it to the wiring terminal 111 of the component 11. When the wire 12 passes through the insulating cylinder 23, pass the wire 12 through the two arc-shaped elastic pieces 24. When the wire 12 passes through the wire management groove 21, pass the wire 12 through the two insulating rubber plugs 22. After the wire 12 is connected to the wiring terminal 111, at this time, the wire 12 is respectively clamped in the insulating rubber plug 22 and the arc-shaped elastic piece 24. Since the surface of the arc-shaped elastic piece 24 is coated with a rubber layer, the situation of electric conduction can be avoided; When tightening the wire 12 extending into the wiring terminal 111 with the locking bolt 112, pull the ring 3 close to the position of the locking bolt 112. The ring 3 will pull the insulating cylinder 23 to gradually approach the component 11 through the insulating rubber band 25. When the ring 3 moves to the thread groove position on the component 11, at this time, the insulating cylinder 23 fits with the component 11, and the wiring terminal 111 is located inside the inner circle of the insulating cylinder 23. Then straighten the wire 12 connected to the wiring terminal 111, then pass the locking bolt 112 through the ring 3 and the annular part 31, and screw the locking bolt 112 into the component 11 to tighten the wire 12 inside the wiring terminal 111. After the locking bolt 112 is tightened, at this time, the locking bolt 112 will press the annular part 31 to fit with the component 11, and the bolt head of the locking bolt 112 will be located inside the ring 3, so as to lock and fix the annular part 31 and the ring 3. Since the annular part 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, generate continuous friction force through elastic deformation, increase the fastening effect of the locking bolt 112, and avoid the self-loosening phenomenon of the locking bolt 112 caused by periodic vibration, resulting in the wire 12 detaching from the wiring terminal 111, and can prevent the fallen wire 12 from accidentally contacting other components 11 or wires 12 inside the power distribution cabinet, forming a short circuit and causing a fire; After all the components 11 are wired, after the power distribution cabinet is debugged, it can be put into use.

[0023] As an implementation method in this embodiment, due to the spring between the insulating cylinder 23 and the insulating rubber plug 22, under the action of elastic force, the insulating cylinder 23 slides out of the wire management groove 21 partially and fits with the surface of the component 11. If the power distribution cabinet endures long-term vibration, resulting in the loosening of the locking bolt 112 and no longer clamping the wire 12 inside the terminal 111, since the wire 12 inserted into the terminal 111 is clamped within the arc-shaped elastic piece 24 and the insulating cylinder 23 fits with the surface of the component 11 under the elastic force of the spring, the wire 12 can be limited and supported, enabling the wire 12 to still be inside the terminal 111 and preventing the wire 12 from detaching from the terminal 111 and accidentally contacting other components 11 or wires 12 inside the power distribution cabinet, thus avoiding the situation of short circuit and fire.

[0024] As another implementation method in this embodiment, due to the tension spring between the insulating cylinder 23 and the insulating rubber plug 22, under the action of tensile force, the insulating cylinder 23 is completely located within the wire management groove 21. When wiring, pull the ring 3 closer to the position of the locking bolt 112, and then pass the locking bolt 112 through the ring 3 and the annular member 31 to lock and fix the ring 3 and the annular member 31. When the annular member 31 and the ring 3 are fixed, at this time, the insulating cylinder 23 fits with the surface of the component 11 and the tension spring is in a stretched state. If the power distribution cabinet endures long-term vibration, resulting in the detachment of the locking bolt 112, since the wire 12 is no longer fixed by the locking bolt 112, the wire 12 will detach from the terminal 111. At the same time, since the ring 3 and the annular member 31 are no longer fixed by the locking bolt 112, under the tensile force of this tension spring, the insulating cylinder 23 will be pulled into the wire management groove 21, and at the same time, it will drive the ring 3 and the annular member 31 to move. Since the wire 12 is clamped by the arc-shaped elastic piece 24, the moving insulating cylinder 23 will use the arc-shaped elastic piece 24 to gradually pull the wire 12 into the wire management groove 21. The wire management groove 21 can block the fallen wire 12, thereby preventing the fallen wire 12 from contacting other components 11 or wires 12 and avoiding the situation of short circuit and fire. At the same time, since both the wire management board 2 and the insulating cylinder 23 have flame retardant properties, the combustion of the insulating cylinder 23 and the wire management board 2 can be avoided.

[0025] As an embodiment of the present invention; a U-shaped clamp 4 is provided around the component 11, and the U-shaped clamp 4 is used to further fix the component 11; The U-shaped clamps 4 are arranged staggeredly with the locking bolts 112, and the two U-shaped clamps 4 are located between the two locking bolts 112 that are opposite to each other up and down; The U-shaped clamp 4 is installed on the guide rail 1 through bolts, and the bolts pass through the guide rail 1 and are threadedly engaged with nuts; In this embodiment, an L-shaped plate 41 is installed on one side of the ring 3 facing the U-shaped clamp 4; the L-shaped plate 41 is hung on the adjacent U-shaped clamp 4 and is in contact with the U-shaped clamp 4; when the L-shaped plate 41 is hung on the U-shaped clamp 4, the centers of the ring 3 and the locking bolt 112 are on the same horizontal plane at this time; One end face of the side of the L-shaped plate 41 in contact with the U-shaped clamp 4 is fixedly connected with a hemispherical body 42; a hemispherical groove 43 is formed on one end face of the side of the U-shaped clamp 4 in contact with the L-shaped plate 41, and the hemispherical body 42 is located in the hemispherical groove 43; In this embodiment, a pin hole penetrates through the ring 3; a pin shaft 32 is inserted into the pin hole, and the pin shaft 32 is made of insulating material; In this embodiment, an interference fit is provided between the annular member 31 and the locking bolt 112; As an implementation manner in 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 bypassed from the component 11, and a bolt is used to pass through the guide rail 1, and a nut is used to fix it on the other side of the guide rail 1, so that the component 11 can be fixed by the U-shaped clamp 4, and the situation that the component 11 falls off under the action of long-term vibration can be avoided; During the implementation process, when the ring 3 and the annular member 31 are locked and fixed by the locking bolt 112, first hang the L-shaped plate 41 on the U-shaped clamp 4. The U-shaped clamp 4 can pull the L-shaped plate 41 and the insulating cylinder 23, so that the pulling force of the tension spring on the insulating cylinder 23 can be offset. When the L-shaped plate 41 is hung on the U-shaped clamp 4, the centers of the ring 3 and the locking bolt 112 are on the same horizontal plane at this time, and then the locking bolt 112 can be used to lock and fix the annular member 31 and the ring 3; During the implementation process, since the pin shaft 32 is inserted into the ring 3, the pin shaft 32 can block the locking bolt 112 located inside the ring 3 to prevent the locking bolt 112 from gradually detaching from the component 11, thereby further improving the locking effect of the locking bolt 112. Since the hemispherical body 42 is provided on the L-shaped plate 41, when the L-shaped plate 41 is hung on the U-shaped clamp 4, the hemispherical body 42 will be stuck in the hemispherical groove 43. Also, since the L-shaped plate 41 bears the pulling force of the insulating cylinder 23, the L-shaped plate 41 can be more tightly attached to the U-shaped clamp 4, 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 shaft 32 is inserted into the ring 3, the blocking effect of the pin shaft 32 on the locking bolt 112 is also improved. Therefore, the bearing capacity of the pin shaft 32 for the thrust generated when the locking bolt 112 loosens can be effectively improved, and the fixing effect of the locking bolt 112 is further improved; During the implementation process, when the locking bolt 112 gradually detaches from the component 11 during the long-term use of the component 11 in a vibrating environment, it will also drive the L-shaped plate 41 to gradually detach from the U-shaped clamp 4. When the locking bolt 112 completely detaches from the component 11, the L-shaped plate 41 completely detaches from the U-shaped clamp 4. Since there is an interference fit between the annular part 31 and the locking bolt 112, after the locking bolt 112 detaches from the component 11, the locking bolt 112 will be restricted within the annular part 31, thereby preventing the locking bolt 112 from falling downward and causing waste due to loss.

[0026] As an embodiment of the present invention; on both sides of the guide rail 1 inside the power distribution cabinet, there are vertical air ducts 5, and both ends of the guide rail 1 and the wire management board 2 are fixedly installed on the air ducts 5 on both sides; On both sides of the power distribution cabinet, there are evenly arranged air inlet slots 51, and fans are installed in the air inlet slots 51; a filter screen is provided in the air inlet slots 51; an air outlet slot is provided on the back of the power distribution cabinet; An air cavity 26 is formed inside the wire management board 2, and the air cavity 26 is communicated with the air duct 5; on one side of the air cavity 26 close to the component 11, there are evenly arranged inclined slots 27; In this embodiment, a through slot 231 is formed on one side of the insulating cylinder 23 close to the air cavity 26; on one side of the air cavity 26 close to the through slot 231, a guide slot 28 is formed, and the guide slot 28 is communicated with the through slot 231; A notch 232 is formed on one side of the insulating cylinder 23 close to the arc-shaped elastic piece 24; As an implementation manner in this embodiment, during the operation of the power distribution cabinet, by controlling the fan to operate, the outside air can be drawn into the air duct 5 through the air inlet slot 51. The air in the air duct 5 will enter the air cavity 26 and then be blown out through the inclined slots 27. The air blown out through the inclined slots 27 will directly act on the component 11, thereby dissipating heat from the component 11; and because the through slot 231 on the insulating cylinder 23 is communicated with the guide slot 28, the air in the air cavity 26 will enter the insulating cylinder 23 through the guide slot 28 and the through slot 231. The air entering the insulating cylinder 23 will continue to flow, and the flowing air will gradually dissipate heat from the terminal 111, and the flowing air will flow out through the notch 232. Finally, the air will flow out through the air outlet slot, enabling the air in the power distribution cabinet to circulate and dissipate heat.

[0027] On the other hand, the present invention also provides a usage method for an intelligent power distribution cabinet. This method is applicable to the above-mentioned intelligent power distribution cabinet and includes the following steps: Step 1: Install the power distribution cabinet in a suitable position and complete the wiring of the main circuit (power input, load output) and the secondary circuit (sensors, communication modules); Step 2: Set the basic parameters of the power distribution cabinet and the delay time of the protection function; in the remote monitoring platform or management software, add the intelligent power distribution cabinet device, configure parameters such as communication protocol, IP address, port number, etc., to ensure the successful connection between the device and the platform; Step 3: Real-time collect the power parameters of each circuit through the intelligent monitoring unit; after the collected data is preliminarily processed by the edge computing unit, on the one hand, it is locally stored, and on the other hand, it is real-time transmitted to the remote monitoring platform through wired or wireless network; Step 4: Log in to the remote monitoring platform through the computer-end management software or mobile phone APP to view the real-time power parameters, device operation status and environmental data of the power distribution cabinet; Step 5: Analyze the collected data. When the power parameters are abnormal (such as current overload, voltage instability) or the environmental parameters exceed the standard (such as too high temperature, detected smoke), immediately trigger the local sound and light alarm, and at the same time send the alarm information to the remote monitoring platform; the platform combines the fault type and historical data.
