Description

Technical Field

[0001] This invention relates to the field of safe power distribution technology, specifically to a safe power distribution device and a safe power distribution system. Background Technology

[0002] In the power distribution field of power companies, distribution cabinets are key equipment that connect upstream power sources with terminal loads (such as lighting, sockets, motors, etc.). They are a general term for motor control centers. Their core functions are to complete the distribution, metering, and control of electrical energy, as well as the protection of lines and electrical equipment. In order to avoid electric shock accidents, a safe power distribution device and a safe power distribution system are needed.

[0003] Existing technology, patent document CN114744497B, discloses an intelligent power distribution terminal and a large-scale power grid security system. This system includes several intelligent power distribution terminals, a communication unit, a cloud server, an alarm system, and a mobile terminal. Through an emergency protection device installed inside the intelligent power distribution terminal, it monitors and automatically extinguishes fires. It releases carbon dioxide to immediately isolate the fire area from oxygen, and the position and size of the oxygen-isolating plate control the opening of ventilation openings, effectively solving the problem of secondary reignition or explosion after a fire in the intelligent power distribution terminal. Furthermore, by utilizing the cooperation of the cloud server, mobile terminal, alarm system, and communication unit, it enables immediate reporting of fires after they occur, allowing relevant personnel to decide whether to take further action, thus comprehensively improving the security level of the power grid.

[0004] Although the existing technology has many beneficial effects, the following problems still exist: During the use of this device, each power distribution unit is installed in the intelligent power distribution terminal using conventional fixed installation and screw wiring. When some circuits fail and need to be replaced, the power must be cut off and professional personnel must use tools to perform tedious wire disassembly and assembly, which is time-consuming and carries high risks of live operation. Secondly, the device has not improved the neutral busbar. The use of traditional centralized fixed busbars with multiple neutral wires screwed in at the same time can easily lead to wiring congestion and difficulty in inspection. Conventional screw tightening can easily loosen and cause poor contact, which needs to be improved. In view of this, we propose a safe power distribution device and a safe power distribution system. Summary of the Invention

[0025] The embodiments of the present invention will now be described in further detail with reference to the accompanying drawings.

[0026] This invention provides an overall structural schematic diagram of an embodiment of a safety power distribution device and a safety power distribution system, comprising: Please see Figures 1-8 This embodiment of a safety power distribution device includes a power distribution cabinet 1. A base 2 is threadedly connected to the inner wall of the power distribution cabinet 1. Multiple circuit breaker assemblies 3 are inserted into the side wall of the base 2. Each circuit breaker assembly 3 includes a circuit breaker body 301. The pluggable circuit breaker body 301 allows for quick replacement in case of fault, making power distribution safer. An operating handle 302 is rotatably connected to the side wall of the circuit breaker body 301. The operating handle 302 facilitates operation by the operator. The top of the circuit breaker body 301... The circuit breaker body 301 has a status window 303 embedded in it. A plug socket 304 is bonded to the back side wall of the circuit breaker body 301. A slot 305 is opened on the top of the plug socket 304. Multiple connectors 306 are embedded in the side wall of the base 2. Multiple pressing plates 307 are slidably connected to the side wall of the base 2. Multiple first springs 308 are welded to the side wall of the pressing plate 307 and located on the inner side wall of the base 2 cavity. The first springs 308 are for rebounding to drive the pressing plate 307 to move and reset so that the moving plate 309 can be reset. The middle of the side wall of the pressing plate 307 is welded There is a movable plate 309, and a locking block 310 is engaged with the inner wall of the slot 305. The locking block 310 is used to engage with the slot 305 to prevent the plug socket 304 from detaching from the connector 306. A connecting plate 311 is welded to the top of the locking block 310. Multiple second springs 312 are welded to the top of the connecting plate 311 and located at the top of the inner cavity of the base 2. The second springs 312 are used to rebound and drive the locking block 310 at the bottom of the connecting plate 311 to move downward and engage inside the slot 305. The top of the side wall of the connecting plate 311 The circuit breaker body 301 is provided with a receiving groove 313. A wedge 314 is welded to the top of the receiving groove 313. The wedge 314 is used to cooperate with the end of the connecting plate 311. When squeezed, the connecting plate 311 moves upward and retracts the locking block 310, which facilitates the insertion and removal of the circuit breaker body 301. A neutral busbar assembly 4 is threaded to the bottom of the inner cavity of the distribution cabinet 1. A central processing unit 5 is threaded to one side of the bottom of the inner cavity of the distribution cabinet 1. The central processing unit 5 is used to summarize and analyze the data of all sensors and execute the preset safety protection logic.

[0027] In some embodiments, the distribution cabinet includes a variety of electrical and electronic components, such as intelligent electric operating mechanisms, door status sensors, disconnect switches, current transformers, voltage transformers, and meters. Due to space limitations, such prior art is not described in detail. The layout of such prior art can be reasonably adapted to this solution and will not affect the normal operation of this solution.

[0028] It is worth noting that, to facilitate increasing the number of neutral busbars as needed, the neutral busbar assembly 4 specifically includes a neutral busbar body 401. A male connector 402 is welded to one side wall of the neutral busbar body 401, and a female connector 403 is welded to the other side wall. The female connector 403 is for insertion and connection with the male connector 402, making it easier and faster to add neutral busbar bodies 401. A wiring hole 404 is provided on the top of the neutral busbar body 401 for inserting the bare end of the neutral wire. The small hole prevents workers from touching the conductive spring contacts. 405 posing a risk of electric shock, a conductive spring 405 is welded to the bottom of the inner cavity of the neutral busbar body 401. The conductive spring 405 is used to squeeze and clamp the bare neutral wire for connection by its own elastic force. An insulating block 406 is attached to the top of the conductive spring 405. The insulating block 406 is used to manually bend the conductive spring 405 to facilitate the insertion of the bare neutral wire end. An arc-shaped groove 407 is opened on the inner side wall of the inner cavity of the neutral busbar body 401. The arc-shaped groove 407 is used to squeeze the arc-shaped part of the conductive spring 405 into the groove, making it easier to squeeze the bare neutral wire end more tightly and preventing the bare neutral wire end from loosening.

[0029] Next, to prevent the circuit breaker body 301 from slipping off, specifically, a copper busbar 201 is welded to the top of the side wall of the base 2, and a support plate 202 is welded to the bottom of the side wall of the base 2. The position of the top of the support plate 202 matches the position of the bottom of the circuit breaker body 301. The copper busbar 201 completes the power distribution and transmission, which facilitates wiring and power supply. The support plate 202 helps to support the circuit breaker body 301, preventing the circuit breaker body 301 from sliding off and falling off and being damaged when the pressing plate 307 is squeezed to remove the circuit breaker body 301.

[0030] Meanwhile, in order to improve installation stability, specifically, notches are opened at the four corners of the side wall of the base 2, and bolts 203 are threaded to the side wall of the four notches. The bolts 203 are screwed in to facilitate the stable installation of the base 2 on the inner side wall of the distribution cabinet 1. The notches prevent the bolts 203 from protruding and interfering with the wiring.

[0031] It is worth noting that, in order to prevent accidental activation of the pressing plate 307, the multiple circuit breaker bodies 301 are specifically divided into single-phase circuit breakers, two-phase circuit breakers, and three-phase circuit breakers. The side wall of the pressing plate 307 is flush with the side wall of the base 2. The single-phase circuit breaker, two-phase circuit breaker, and three-phase circuit breaker can meet different needs, effectively cut off fault current and prevent single-phase operation. The pressing plate 307, which is flush with the side wall of the base 2, avoids protrusion that could lead to accidental activation and affect the insertion stability of the circuit breaker body 301.

[0032] Secondly, to integrate multiple functions into the plug socket 304, specifically, the middle insert of the inner cavity side wall of the plug socket 304 is injection molded with multiple main circuit pins 315, the lower side insert of the inner cavity side wall of the plug socket 304 is injection molded with a grounding pin 316, and the other side insert of the lower side insert of the inner cavity side wall of the plug socket 304 is injection molded with multiple auxiliary contact pins 317. The auxiliary contact pins 317 are used to transmit the "fault trip" status signal inside the module to the system and to transmit the "closing / opening" status signal. The upper insert of the inner cavity side wall of the plug socket 304 is injection molded with multiple control communication pins 318. The grounding pin 316 is longer than the main circuit pins 315, auxiliary contact pins 317, and control communication pins 318. The longer grounding pin 316 ensures that it is connected first when inserted and disconnected last when removed, ensuring safety.

[0033] Next, to prevent the circuit breaker body 301 from falling off due to the loosening of the plug socket 304, specifically, the size and position of the movable plate 309 match the size and position of the receiving groove 313, the cross-section of the locking block 310 is a right-angled triangle, and the size and position of the locking groove 305 match the size and position of the locking block 310. With the movable plate 309 matching the size and position of the receiving groove 313, it is easy for the connecting plate 311 to move accurately when the movable plate 309 is pressed and moved. With the locking block 310 with a right-angled triangular cross-section, it is easy for the plug socket 304 to be inserted and squeezed by the inclined surface of the locking block 310 to move the locking block 310 upward. The locking block 310 is locked into the locking groove 305 and cannot make the plug socket 304 move in the opposite direction, thus preventing the plug socket 304 from loosening.

[0034] Furthermore, to facilitate the installation of the neutral busbar body 401, specifically, the female connector 403 has multiple elastic contact pieces welded inside the groove on its side wall, and the male connector 402 has multiple metal pins welded to its side wall. The structure of the female connector 403 matches the structure of the male connector 402. The matching structure of the female connector 403 and the male connector 402 facilitates the metal pins and elastic contact pieces to easily insert and remove the connectors, making installation faster.

[0035] Then, to prevent safety accidents, specifically, a temperature sensor 6 is threadedly connected to the side wall of the neutral busbar assembly 4, and an audible and visual alarm 7 is threadedly connected to the side wall of the inner cavity of the distribution cabinet 1. The audible and visual alarm 7 is electrically connected to the external power supply. The temperature sensor 6 monitors the temperature of the busbar connection point in real time to prevent safety accidents such as overheating and melting, electrical fires caused by loose joints and oxidation. When the system detects faults such as leakage, overheating, or short circuit, the audible and visual alarm 7 uses high-frequency flashing lights and a piercing buzzer sound to provide on-site alarm, reminding on-site personnel to pay attention to the danger and deal with it in time.

[0036] The safety power distribution system of the safety power distribution device includes the following processes: First, the sensing layer continuously collects system data. The sensing layer includes current and voltage sensors installed inside the pluggable circuit breaker module, a wireless temperature sensor 6 integrated into the modular neutral busbar connection point, and a door status sensor installed on the distribution cabinet door. Subsequently, the central processing unit 5 receives and analyzes the sensor data, compares the data with a preset safety threshold, and determines whether the system is in an abnormal state of overload, short circuit, overheating or insulation failure. If the judgment result is abnormal, the central processing unit 5 immediately sends a trip command to the corresponding pluggable circuit breaker module where the abnormality occurred, and triggers the audible and visual alarm 7 on the distribution cabinet to issue an on-site alarm. If the judgment result is normal, the central processing unit 5 stores the sensor data in the local memory and uploads the data to the remote monitoring center or user terminal through the communication module. Finally, through the above steps, the system achieves the core objective of safe power distribution by quickly disconnecting faulty circuits, providing early warnings of potential dangers, and remotely monitoring the system's operating status.

[0037] In addition, the circuits, electronic components, and modules involved in this invention are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon. Furthermore, the scope of protection of this invention does not involve improvements to the internal structure and methods. Combination Figures 1-8 The specific usage process of the safety power distribution device and safety power distribution system of this embodiment is as follows: 1. When this device is needed for use as a safety power distribution device and safety power distribution system, when it is necessary to install the circuit breaker assembly 3, align the plug socket 304 on the back of the circuit breaker body 301 with the connector 306 on the side wall of the base 2 and insert it. The top of the plug socket 304 contacts and presses the inclined surface of the wedge block 314, causing the wedge block 314 to be pushed by force to move the connecting plate 311 upward. After the plug socket 304 is fully inserted, the second spring 312 rebounds and drives the connecting plate 311 and the locking block 310 downward, so that the locking block 310 is locked into the slot 305, completing the locking. When a fault occurs and the circuit breaker assembly 3 needs to be disassembled separately, press the pressing plate 307 with your finger to drive the moving plate 309 to move inward and compress the first spring 308, so that the end of the moving plate 309 presses the inclined surface of the wedge block 314, causing the wedge block 314 to drive the connecting plate 311 upward, thereby causing the locking block 310 to disengage from the slot 305, and pull out the circuit breaker body 301 to complete the disassembly. 2. When it is necessary to expand the neutral busbar, directly insert the male connector 402 of one neutral busbar body 401 into the female connector 403 of another neutral busbar body 401 to complete the quick splicing of the neutral busbar. When it is necessary to connect the neutral wire, manually turn the insulating lever 406 to cause the conductive spring 405 to bend and deform, so that its clamping end opens. Insert the prepared bare neutral wire end vertically into the wiring hole 404 until the predetermined depth is reached. Release the insulating lever 406, and the conductive spring 405 restores its deformation by its own elasticity, pressing the bare neutral wire end into the arc groove 407 to complete the connection.

[0038] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention. In particular, as long as there is no structural conflict, the features in the disclosed embodiments can be combined with each other in any manner. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

10. The safety power distribution system of the safety power distribution device according to any one of claims 1-9, characterized in that, The process includes the following steps: First, the sensing layer continuously collects system data. The sensing layer includes current and voltage sensors installed inside the pluggable circuit breaker module, a wireless temperature sensor (6) integrated into the modular neutral busbar connection point, and a door status sensor installed on the distribution cabinet door. Subsequently, the central processing unit (5) receives and analyzes the sensor data, compares the data with a preset safety threshold, and determines whether the system is in an abnormal state of overload, short circuit, overheating or insulation failure. If the judgment result is abnormal, the central processing unit (5) immediately sends a trip command to the corresponding pluggable circuit breaker module that has the abnormality, and triggers the sound and light alarm (7) on the distribution cabinet (1) to issue an on-site alarm. If the judgment result is normal, the central processing unit (5) stores the sensor data in the local memory and uploads the data to the remote monitoring center or user terminal through the communication module. Finally, through the above steps, the system achieves the core objective of safe power distribution by quickly disconnecting faulty circuits, providing early warnings of potential dangers, and remotely monitoring the system's operating status.
