Description

Technical Field

[0001] This utility model relates to the field of electrical power distribution equipment, and in particular to an intelligent safety distribution box with structural safety and intelligent monitoring and protection functions. Background Technology

[0002] As an indispensable component of the power system, the safety and reliability of distribution boxes are crucial for ensuring a stable power supply and safe electricity use.

[0003] Traditional distribution boxes have some shortcomings in terms of structural design and function:

[0004] 1) Insufficient structural protection: Many distribution boxes have switches, sockets and other operating components that protrude directly from the box surface. They are easily damaged by accidental collisions during transportation, installation or use, affecting normal use or even causing safety hazards.

[0005] 2) Heat dissipation problem: In pursuit of airtightness, some distribution boxes neglect the heat dissipation requirements of internal components. Especially in a closed environment or under high load, excessively high internal temperature can easily lead to a decline in component performance, accelerated aging, and even fire.

[0006] 3) Low level of intelligence: Traditional distribution boxes are mostly pure power distribution and basic protection devices, lacking intelligent functions such as real-time monitoring, fault early warning, and remote control, making it difficult to meet the needs of modern refined and intelligent power management. Once a fault occurs, manual on-site inspection is often required, resulting in slow response and affecting the continuity of power supply.

[0007] 4) Safety hazards: In addition to physical damage and overheating, electrical faults such as overvoltage, overcurrent, and leakage are also common safety hazards in distribution boxes. Traditional protection devices are not timely enough or have limited functions, making it difficult to provide comprehensive coverage.

[0008] Therefore, how to design a distribution box with a safer structure, more efficient heat dissipation, and more intelligent functions to improve its overall performance and user experience is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] Please see Figures 1-10 As shown, this utility model provides an intelligent safety distribution box, the core structure of which includes a box body 100, multiple electrical functional areas and corresponding electrical components arranged inside the box body 100, a ventilation and heat dissipation system, and an intelligent control unit.

[0039] Please see Figure 1 and Figure 2As shown, the enclosure 100 is typically made of metal, specifically cold-rolled steel sheet, possessing sufficient mechanical strength. The overall design of the enclosure 100 meets an IP54 protection rating, effectively preventing dust and water splashes from entering, making it suitable for various industrial or outdoor environments. The enclosure 100 has a door on the front, and an air inlet 101 is located on the door or at other suitable locations on the enclosure 100, for example, please refer to [reference needed]. Figure 1 The two square "air inlets" shown in the image.

[0040] The interior of enclosure 100 is divided into several independent or relatively independent areas according to its function and purpose. Please refer to [link / reference]. Figure 1 , Figure 3 and Figure 4 As shown, including: For example, please refer to [link / reference]. Figure 1 The "400A Incoming Line Area" or the area marked in the middle Figure 2 The "630A Incoming Line Area" is used to introduce external power and install the main incoming line switch, such as a "380V / 400A Intelligent Control Switch" or a "380V / 630A Intelligent Control Switch". This intelligent control switch is integrated into the intelligent control unit and has monitoring and control functions.

[0041] Please refer to Figure 3 Its 380V operating area is equipped with electrical components for 380V voltage levels, such as 380V / 250A incoming line sockets, which can be found in Figure 1 , Figure 2 380V / 63A socket, please refer to Figure 3 The sockets in the area marked "1. Angled Design" and the corresponding control switches, such as "6-position switch" and "2-position switch".

[0042] Please refer to Figure 4 Its 220V working area is equipped with electrical components for the 220V voltage level, such as a 220V / 16A incoming socket and corresponding control switches, such as a "6-position switch" or a "3-position switch".

[0043] Please refer to Figure 3 Its 36V working area is equipped with electrical components for the 36V safety voltage level, such as 36V / 32A sockets, typically used to connect handheld power tools or temporary lighting equipment. This partitioned design makes the internal layout clear, separating strong and weak current circuits, facilitating installation, wiring, maintenance, and management, while also improving operational safety.

[0044] One important feature of this utility model in terms of the protective installation structure of electrical components is its installation method.

[0045] Please see Figure 3As shown, the mounting panels of each functional area inside the enclosure 100 are used to install power sockets 104, such as 380V / 63A sockets, 220V / 16A sockets, and 36V / 32A sockets. Please refer to the cross-sectional structures for details. Figure 9 CC section, Figure 10 EE section, Figure 9 The DD cross-section shown and examples of the cross-sectional structures of circuit breakers 105, such as various "position switches," can also be seen in... Figure 7 FF cross section, Figure 8 BB cross section, Figure 9 and Figure 10 Its location employs a special structural design.

[0046] Specifically, the mounting surfaces of socket 104 and circuit breaker 105 are designed with a bevel, not perpendicular to the mounting panel, but at a certain angle. This bevel design facilitates user insertion and removal, and also helps prevent dust and small amounts of water from accumulating directly on the socket or operating handle. The angle of the bevel can be optimized according to the size of the specific components and ergonomics. Combined with the bevel design, after socket 104 and circuit breaker 105 are installed as a whole through a recessed design, their operating surfaces, such as the socket's socket side and the circuit breaker's handle front, are basically flush with or slightly recessed from the mounting panel surface of the housing 100. Please refer to [link to relevant documentation]. Figure 7 The middle FF section, Figure 8 Middle BB section Figure 9 and Figure 10 As shown in the cross-sectional structure, the main body of the component is recessed below the panel.

[0047] This combination of "sloping surface + concave surface" design provides effective physical protection for these externally connected and operated electrical components, preventing damage or misoperation caused by accidental impacts or scratches when the distribution box is moved, installed, or used in crowded workplaces due to its protruding surface. Figure 3 The labels “sloping surface design” and “concave surface design” clearly indicate this structural feature.

[0048] In addition, please see Figure 3 As shown, some sockets and switches also adopt "detachable design", "socket easy-to-remove design", and "switch easy-to-remove design", which indicates that their installation and fixing methods facilitate quick disassembly and replacement, reducing maintenance difficulty and time costs.

[0049] To ensure that the enclosure 100 can still effectively dissipate heat under an IP54 sealing rating, this utility model has designed a complete ventilation and heat dissipation system.

[0050] Please see Figure 1As shown, one or more air inlets 101 are provided on the lower part of the front panel of the cabinet 100, such as below the cabinet door, through which cold air enters the interior of the cabinet.

[0051] Please also see Figure 5 and Figure 8 As shown in the BB section, at the top of the enclosure 100, i.e. below the top plate, at least one, typically two or more, exhaust fans 102 are installed. Figure 5 The diagram illustrates two "fans". When exhaust fan 102 is working, it draws hot air out of the casing.

[0052] In addition, please see Figure 5 As shown, the top of the housing 100 is covered by a top cover 103, and an air outlet 108 is provided. This top cover 103 can be designed as a rainproof structure with a certain slope; see example [link to example]. Figure 7 The "rainproof roof" structure shown in section FF, or please refer to [link to relevant documentation]. Figure 8 The top cover structure shown in the BB section prevents rainwater from getting in directly.

[0053] The edges of the top cover 103, such as the front and rear edges, have multiple air vents 108, such as the "waist-shaped holes" or strip-shaped holes mentioned in the technical disclosure document. Please refer to [link / reference]. Figure 5 A diagram of the top edge.

[0054] Hot air is drawn out by the exhaust fan 102 and discharged to the outside of the enclosure through the air outlets 108. The top cover 103 can be designed to be removable for easy maintenance of the top fan and other components.

[0055] To optimize airflow, please refer to Figure 7 As shown in the "Airflow Guidance View" and arrows in the FF section, Figure 8 The BB section also illustrates a similar airflow path. Guided by the air duct, cold air enters from the lower air inlet 101 and forms an upward airflow inside the housing. It flows through the internal heat-generating electrical components, absorbs heat, and is then extracted by the upper exhaust fan 102.

[0056] An airflow guiding structure 107, such as a partition or a specific layout, can be installed inside the enclosure to optimize the airflow path and ensure heat dissipation efficiency. Figure 6 The terms "upper layer" and "lower layer" in the text also imply the stratification or guidance of the internal air.

[0057] The "intelligence" of this utility model is mainly achieved through its built-in intelligent control unit and its various functions.

[0058] This unit typically includes a microprocessor, a data acquisition module (i.e., sensor interface), a communication module, a protection logic execution module, and a human-machine interface. It can monitor parameters in real time through connected sensors, such as voltage transformers, current transformers, and temperature sensors, including key operating parameters such as voltage, current, frequency, power factor, active power, reactive power, and internal temperature of the incoming line and each circuit.

[0059] To enable data display and interaction, please refer to [link / reference]. Figure 1 and Figure 2 As shown, a touch screen 106, such as a "7-inch" or "10-inch" screen, can be installed on the front panel of the enclosure 100 to display the above-mentioned monitoring parameters, equipment status, alarm information, etc. in real time, and to allow users to perform local parameter settings, mode switching, manual control and other operations.

[0060] The intelligent control unit also incorporates multiple protection algorithms to achieve intelligent protection, including: automatically disconnecting the corresponding circuit when the voltage exceeds the preset safety range to achieve overvoltage / undervoltage protection; tripping in time when the current continuously exceeds the rated value or a short circuit occurs to provide overcurrent / overload protection; quickly cutting off the power supply when the line leakage current reaches a set threshold to prevent electric shock, which is its leakage protection function; and suppressing instantaneous overvoltages caused by lightning strikes or the start-up and shutdown of large equipment to provide surge protection and protect downstream equipment.

[0061] Meanwhile, by monitoring the temperature inside the enclosure or key components, an alarm is triggered or a derating / shutdown operation is performed when the temperature is too high, thus achieving temperature protection.

[0062] Furthermore, the intelligent control unit, through its built-in communication modules such as Ethernet, RS485, GPRS / 4G / 5G, uploads collected data and equipment status to a remote smart power management platform or user monitoring center, thereby achieving remote monitoring and control. Authorized users can remotely view the real-time operating status of the distribution box via PC or mobile APP, receive fault alarms, and execute remote opening and closing control commands, greatly improving the convenience and response speed of management. Through the analysis of historical and real-time data, the intelligent control unit or upper-level system can also perform a certain degree of fault diagnosis and early warning. For example, it can judge equipment aging through abnormal current fluctuations or warn of abnormal heat dissipation systems through persistently high temperatures, providing a basis for preventive maintenance.

[0063] When this intelligent safety distribution box is put into use, external power is introduced through the intelligent control switch in the incoming line area. The electrical components in each working area, namely sockets and circuit breakers, supply power to downstream electrical equipment. The intelligent control unit continuously monitors various electrical parameters. Users can view the real-time status through the display screen 106 on the front of the box. In the event of an overload, the intelligent control unit detects the excessive current and immediately controls the corresponding circuit breaker to trip, issuing an alarm through the display screen and the remote system.

[0064] Meanwhile, the ventilation and heat dissipation system operates continuously. Air inlet 101 draws in cooler outside air, which flows through the internal components, carrying away heat. Finally, the exhaust fan 102 at the top exhausts the hot air through outlet 108 on the top cover 103, maintaining the internal temperature within a reasonable range. Because the sockets and circuit breakers are installed with recessed angled surfaces, damage from impacts can be effectively avoided even in complex field environments.

[0065] In summary, this utility model, through comprehensive and innovative design of the distribution box's box structure, component installation method, ventilation and heat dissipation system, and intelligent monitoring and protection functions, effectively solves many problems existing in the prior art, significantly improves the safety, reliability, durability, and intelligent management level of the distribution box, and has broad application value.

[0066] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
