Description

Technical Field

[0001] This utility model relates to the field of electrical equipment technology, and in particular to an ATS switching cabinet with a modular partition layout. Background Technology

[0002] ATS (Automatic Transfer Switch) cabinets, as key devices for automatically switching between primary and backup power sources, play an indispensable role in scenarios with extremely high requirements for power supply continuity, such as data centers, hospitals, communication base stations, financial institutions, and photovoltaic energy storage. Their core function is to quickly and reliably switch the load to a backup power source (such as a generator or energy storage system) when a failure of the primary power source (such as mains power) is detected, thereby ensuring the uninterrupted operation of critical loads.

[0003] In existing technologies, the internal design of ATS switching cabinets generally adopts an integrated or hybrid layout. Specifically, the ATS switch body that realizes power switching, circuit breakers and other high-voltage components for line protection, and low-voltage components such as PLCs (Programmable Logic Controllers), relays, and control power supplies responsible for logic control, as well as communication components such as Ethernet modules and wireless gateways for remote monitoring, are usually installed together on the mounting back panel of the same enclosure, lacking systematic functional zoning planning. This hybrid layout has revealed a series of inherent technical defects in long-term application.

[0004] One prominent problem is the serious electromagnetic compatibility (EMC) issue. Inside the cabinet, the high-current power busbars and power cables are powerful sources of electromagnetic interference, generating strong electromagnetic fields during steady-state operation and switching actions. Meanwhile, the PLC's CPU, input / output signal lines, and Ethernet communication cables—the low-voltage and high-frequency components—are highly susceptible to interference from external electromagnetic fields. When these cables of different types are arranged adjacently, parallel, or intersecting within the cabinet, the electromagnetic field from the high-voltage circuit can couple into the low-voltage and communication lines through induction or radiation, generating noise signals. This can lead to PLC controller logic misjudgments, issuing incorrect commands, or causing communication data packet loss and transmission interruptions. In severe cases, it can cause system shutdown or switching failures, directly jeopardizing the reliability of the power supply.

[0005] Secondly, the chaotic structure leads to low installation and maintenance efficiency. Due to the lack of clear layout rules, the wiring inside the cabinet is intricate and complex, with cables of different functions tangled together, forming a so-called "spider web" of cabling. This not only increases the difficulty and time required for initial installation and commissioning but also poses a significant challenge to subsequent operation and maintenance. When equipment malfunctions, technicians must painstakingly troubleshoot and locate the problem amidst the messy cables; replacing a single component may require dismantling numerous unrelated lines, greatly prolonging troubleshooting time and increasing maintenance costs.

[0006] In summary, the hybrid internal layout commonly used in existing ATS switching cabinets has significant shortcomings in terms of electromagnetic compatibility, ease of installation and maintenance, and operational safety, and can no longer meet the requirements of high reliability, high efficiency, and high safety in modern critical power supply scenarios. Utility Model Content

[0007] To address the technical problems existing in the prior art, this utility model provides a modular partitioned ATS switching cabinet. It aims to solve the technical problems caused by the mixed layout of high-voltage, low-voltage, and communication lines in the prior art, such as electromagnetic interference, wiring confusion, safety risks, and maintenance difficulties, by functionally partitioning the internal space of the ATS switching cabinet and matching the corresponding partition outgoing line design.

[0008] This utility model discloses a modular partitioned layout ATS switching cabinet, including a cabinet body. The cabinet body is equipped with high-voltage control components, low-voltage control components, and data communication components. The cabinet body is equipped with a high-voltage outlet, a low-voltage outlet, and a communication outlet on the outside.

[0009] The cabinet is internally divided into a high-voltage zone, a low-voltage zone, a communication zone, and a reserved auxiliary and human-machine interaction zone; the high-voltage control components, low-voltage control components, and data communication components are respectively located in the high-voltage zone, low-voltage zone, and communication zone; the auxiliary and human-machine interaction zone is equipped with human-machine interaction components and auxiliary function components.

[0010] The high-voltage outlet, low-voltage outlet, and communication outlet are installed in staggered positions and correspond to the high-voltage area, low-voltage area, and communication area, respectively, and are electrically connected to the high-voltage control element, low-voltage control element, and data communication element, respectively.

[0011] Optionally, the high-voltage control components installed in the high-voltage area include at least: an ATS automatic transfer switch body, a circuit breaker for protection of mains power and backup power supply incoming lines, a main busbar for large current distribution and collection, a power supply side surge protector, a current transformer, or a large-diameter power cable terminal block.

[0012] Optionally, the low-voltage control components include at least: a programmable logic controller, an intermediate relay, a time relay, a miniature circuit breaker or fuse for the control circuit, a 24V DC switching power supply, or a control signal terminal block.

[0013] Optionally, the data communication element includes at least: an Ethernet switch, a protocol conversion gateway, a 4G / 5G / WiFi wireless communication module, an optical transceiver, or a communication interface terminal.

[0014] Optionally, the human-computer interaction element includes at least: a human-computer interaction interface, indicator lights, selection switches, operation buttons, or emergency stop buttons;

[0015] The auxiliary functional components include at least: a cooling fan, a heater, or a temperature and humidity controller.

[0016] Preferably, the low-pressure area is a long rectangular region and is provided with at least one DIN rail or multiple parallel DIN rails.

[0017] The DIN rail is arranged along the long side of the long rectangular area in the low-voltage zone, and multiple low-voltage control components that need to be connected in parallel are arranged in a straight line and snapped onto the DIN rail.

[0018] Preferably, the high-pressure zone is a rectangular area located close to one end of the low-pressure zone and is arranged perpendicular to the low-pressure zone, which is a long rectangular area.

[0019] Preferably, the communication area is located in a corner of the cabinet, away from the high-voltage area and at a certain distance from the low-voltage area;

[0020] The communication area is at a certain height above the high-voltage area and the low-voltage area in the depth direction of the cabinet.

[0021] Preferably, the auxiliary and human-machine interaction area is a rectangular area with its two sides close to the high-pressure area and the low-pressure area, respectively.

[0022] Optionally, metal isolation plates are respectively provided at the junctions of the high-voltage zone, low-voltage zone, communication zone and auxiliary and human-machine interaction zone. The bottom of the metal isolation plate is provided with a clearance notch for avoiding circuit board lines. The metal isolation plate is also provided with several through holes for circuit flying wires to pass through. The metal isolation plate is connected to a grounding wire.

[0023] The modular partitioned layout ATS switching cabinet of this utility model can achieve the following significant beneficial effects:

[0024] First, by placing the high-voltage control components that generate strong electromagnetic interference, the low-voltage control components that are sensitive to interference, and the data communication components in physically isolated high-voltage, low-voltage, and communication zones respectively, the coupling path of interference can be effectively isolated. This structural design concentrates the strong electric field in the high-voltage zone, which reduces electromagnetic interference to low-voltage control signals and high-frequency communication data, thereby improving the stability and reliability of system operation.

[0025] Secondly, the one-to-one correspondence between internal functional zones and external cable outlets makes both internal cabling and external wiring clear and organized. Installers can perform modular cabling by area, greatly simplifying the installation process, shortening the construction cycle, and reducing the error rate. Similarly, during troubleshooting and maintenance, technicians can quickly locate specific functional areas and perform targeted operations without affecting the normal operation of other areas, significantly improving maintainability.

[0026] Third, the separation between the high-voltage area and the low-voltage operating area provides a reliable safety barrier for maintenance personnel, effectively avoiding the risk of accidentally touching high-voltage components and improving the safety of the equipment throughout its entire life cycle.

[0027] Fourth, by establishing a separate auxiliary and human-machine interaction area, centralized management of the operating interface and environmental control functions can be achieved. Components in this area (such as the human-machine interface, operating buttons, and cooling fans) are less sensitive to electromagnetic interference due to their inherent electrical characteristics. Grouping these components together allows designers to flexibly arrange them in easily observable or operable locations based on ergonomics and space utilization, without requiring the same level of strict isolation from core functional areas such as high and low voltage zones. This layout structure based on component characteristics further optimizes the internal space layout of the ATS switching cabinet without sacrificing overall electromagnetic compatibility performance, improves the convenience of local operation, and ensures the complete functional configuration of the cabinet.

[0036] like Figures 1 to 3 As shown in this embodiment, a modular partitioned layout ATS switching cabinet aims to solve problems in existing ATS switching cabinets such as chaotic internal structure, severe electromagnetic interference caused by mixed arrangement of strong and weak current circuits, difficult installation and wiring, and potential safety hazards. This ATS switching cabinet includes a cabinet 1, whose internal space is innovatively divided into four functionally defined areas that are physically isolated or maintain a safe distance from each other. Specifically, the cabinet 1 is divided into a high-voltage area 2, a low-voltage area 3, a communication area 4, and a reserved area for auxiliary and human-machine interaction 5. This modular partitioned design is the core of this embodiment; by classifying and physically isolating components with different electrical characteristics and functions, it optimizes the electromagnetic environment and physical layout inside the cabinet.

[0037] Corresponding to the internal zoning, high-voltage outlet 6, low-voltage outlet 7, and communication outlet 8 are provided on the outer wall of cabinet 1. These outlets are staggered and adjacent to their respective internal functional areas: high-voltage outlet 6 corresponds to high-voltage area 2, low-voltage outlet 7 to low-voltage area 3, and communication outlet 8 to communication area 4. This internal-external correspondence design makes the entry and exit paths of external cables clear and unambiguous, avoiding the tangling of cables of different types during on-site installation and simplifying the construction process.

[0038] Within high-voltage zone 2, high-voltage control components for handling the main power circuit are centrally located. These components are the main channels and protection nodes for energy flow. In this embodiment, the high-voltage control components may include: the core actuator for switching between mains power and backup power—the ATS automatic transfer switch body; molded case circuit breakers or miniature circuit breakers for providing overload and short-circuit protection for the mains and backup power input lines; main busbars for large current distribution and collection; power-side surge protectors for absorbing grid surge voltages and preventing lightning damage to equipment; and current transformers for monitoring the main circuit current and providing real-time data to the monitoring system. Additionally, large-gauge power cable terminals for connecting large-section power cables may also be included. Centralizing these components, which generate strong electromagnetic fields and significant heat, within high-voltage zone 2 facilitates unified electromagnetic shielding, heat dissipation management, and safety isolation.

[0039] Within low-voltage zone 3, low-voltage control components are centrally located as the control system, responsible for logic judgment, timing control, and instruction execution. In this embodiment, these low-voltage control components may include: a programmable logic controller (PLC) or dedicated intelligent logic controller serving as the core of the ATS switching logic; intermediate relays and time relays for signal isolation, voltage conversion, and drive capability amplification; miniature circuit breakers or fuses for protecting the entire low-voltage control loop; a 24V DC switching power supply providing stable operating voltage for the PLC, sensors, relays, etc.; and control signal terminal blocks for connecting external control signals (such as generator start signals) and status feedback signals.

[0040] Furthermore, to achieve efficient assembly and standardized wiring, low-voltage zone 3 is designed as a long rectangular area. One or more parallel DIN rails are arranged along its long side within this area. Most low-voltage control components, such as PLC modules, relays, and terminal blocks, use a standard DIN rail snap-fit ​​design, allowing for quick and neat snap-fit ​​onto the DIN rails. This design not only significantly improves assembly efficiency but also allows multiple low-voltage control components that need to be connected in parallel (such as components sharing a 24V power supply) to be arranged in a straight line, facilitating the use of cable trays for organization. This results in neat and clear power and signal wiring paths, minimizing wiring confusion and crossings, and providing significant convenience for subsequent maintenance and troubleshooting.

[0041] To achieve better electromagnetic compatibility (EMC), the high-voltage zone 2 is designed as a rectangular area, and is arranged perpendicularly to the low-voltage zone 3, which is a long rectangular area. Specifically, in this embodiment, the low-voltage zone 3 on the left is arranged vertically along the height of the cabinet 1, while the high-voltage zone 2 on the lower right is arranged horizontally along the width of the cabinet 1, with the high-voltage zone 2 close to the lower end of the low-voltage zone 3. This 90-degree cross layout is a classic EMC design scheme. Its technical principle is that the electromagnetic induction intensity is proportional to the parallel coupling length between the interference source and the interfered conductor. The high-current busbars or power cables in the high-voltage zone 2 will generate a strong magnetic field. If they run parallel to the control signal lines of the low-voltage zone 3 for a long time, they will generate the maximum induced noise. By adopting a mutually perpendicular layout, the parallel coupling path between the high-voltage circuit and the low-voltage signal line is shortened to only one intersection point, thereby minimizing induced interference and effectively preventing precision controllers such as PLCs from making misjudgments or logic errors due to noise signals, ensuring the accuracy of system control.

[0042] Within communication zone 4, data communication elements are installed as part of the system's communication network, responsible for exchanging data with the host computer monitoring system, cloud platform, etc. In this embodiment, these data communication elements may include: an Ethernet switch for building a local network; a protocol conversion gateway for converting between different communication protocols, such as Modbus RTU to Modbus TCP; a 4G / 5G / WiFi wireless communication module for remote wireless data transmission; and fiber optic transceivers and corresponding communication interface terminals (such as RJ45, DB9, etc.) for long-distance, high-interference-resistant fiber optic communication.

[0043] Considering that data communication signals, especially high-frequency signals, are extremely sensitive to electromagnetic interference, communication zone 4 is located far away from strong interference sources. Specifically, communication zone 4 is positioned in the upper left corner of cabinet 1, physically away from high-voltage zone 2 and maintaining a safe distance from low-voltage zone 3. The ATS switch in high-voltage zone 2 generates strong electric arcs and electromagnetic pulses during switching, and the relay coil switching in low-voltage zone 3 also generates conducted and radiated noise; these are significant sources of interference for high-frequency communication. By maximizing the physical distance, the spatial attenuation effect can be utilized to economically and effectively weaken the interference field strength, thereby ensuring the integrity of communication data packets and preventing remote monitoring failure due to data errors or loss. Furthermore, as... Figure 2 As shown, in this embodiment, the communication area 4 can also be higher than the high voltage area 2 and the low voltage area 3 in the depth direction of the cabinet 1 by a certain height, forming a three-dimensional spatial isolation, further enhancing the anti-interference effect.

[0044] Within the auxiliary and human-machine interface area 5, human-machine interface components and auxiliary function components are installed. This area is typically located inside the cabinet door or on a separate panel easily visible and accessible to the operator. Human-machine interface components may include: a human-machine interface (HMI) or touchscreen for graphically displaying system operating status, setting parameters, and performing manual operations; indicator lights for visually indicating power, closing, opening, and fault status; a selector switch for switching between automatic and manual modes; operation buttons for forced switching and reset operations; and an emergency stop button for cutting off all power in emergencies. Auxiliary function components may include: a cooling fan for forced convection cooling; a heater to prevent condensation and ensure normal component operation in low-temperature environments; and a temperature and humidity controller for automatically controlling the start and stop of the fan and heater.

[0045] Grouping these components into a separate area is based on a comprehensive consideration of their functional characteristics and electromagnetic susceptibility. On the one hand, HMIs, buttons, and other components need to be user-facing and must be placed in easily accessible locations; on the other hand, these components themselves have naturally low sensitivity to electromagnetic interference or good internal shielding. For example, HMIs have robust internal shielding, while indicator lights, buttons, and other switching signals have high judgment thresholds and are not easily affected by weak induced noise. Fans, heaters, and other components are power devices, and their operation is largely unaffected by external electromagnetic fields. Due to the stability of these components, the auxiliary and human-machine interaction area 5 can be designed as a rectangular area, with its sides close to the high-voltage area 2 and the low-voltage area 3 respectively, thus optimizing the space utilization within the cabinet without sacrificing system reliability. This refined layout based on the differences in component characteristics reflects a more rational design structure.

[0046] To achieve reliable physical isolation and electromagnetic shielding between functional areas, metal isolation plates 9 are installed at the junctions between high-voltage area 2, low-voltage area 3, communication area 4, and auxiliary and human-machine interaction area 5. These metal isolation plates 9 clearly separate the cabinet space, effectively preventing maintenance personnel from accidentally touching high-voltage live parts when operating the low-voltage area or human-machine interaction area, thus improving safety. Simultaneously, the metal isolation plates 9 also form part of a Faraday cage, providing shielding against electromagnetic waves. To achieve necessary electrical connections between areas, the bottom of the metal isolation plates 9 has clearance notches 92 for avoiding circuit board lines. Rubber pads can be added to the surface of the clearance notches 92 for insulation to prevent leakage. Furthermore, the metal isolation plates 9 also have several through holes 91 for passing overhead wires, facilitating necessary overhead wire operations by electricians during maintenance. To ensure shielding effectiveness, the metal isolation plates 9 are reliably grounded via a grounding wire 10. This ensures that electromagnetic interference current induced on the plates is effectively conducted to the ground, rather than radiating to adjacent sensitive areas.

[0047] To further enhance the system's intelligent monitoring and fault early warning capabilities, this embodiment innovatively extends the aforementioned grounding shielding structure. Specifically, a Hall current sensor (not shown in the figure) is added, with its detection end positioned in the grounding loop of the metal isolation plate 9. The grounding wire 10, after exiting the metal isolation plate 9, is not directly connected to the grounding busbar, but first passes through the detection hole of the Hall current sensor before connecting to the main grounding device of the cabinet 1. The power supply for the Hall current sensor is provided by the switching power supply in the low-voltage zone 3, and its signal output is electrically connected to the control system, such as connecting to the analog input interface of the PLC or the controller in the communication zone 4. Since the Hall current sensor itself is a non-contact measurement, its equivalent impedance in the circuit is extremely small, and it will not affect the current discharge capacity of the grounding loop. Simultaneously, a Hall current sensor with a sufficient insulation withstand voltage rating (e.g., 2500V) is selected to ensure reliable electrical isolation between the high-voltage zone and the low-voltage control system, preventing the introduction of safety risks. The technical principle of this design is that the electromagnetic radiation generated in high-voltage zone 2 is absorbed by the metal isolation plate 9, inducing a current on the plate. This current is conducted to the ground through the grounding wire 10. A Hall current sensor can accurately measure the intensity of this induced current. By monitoring the changes in this current value in real time, the control system can indirectly reflect the changing trend of electromagnetic interference intensity within the cabinet. Under normal operating conditions, this induced current will remain within a relatively stable range, for example, fluctuating between 10-100mA depending on the load changes in the high-voltage zone. The control system can preset a "normal threshold range" accordingly. When the monitored current value is abnormal, the control system can execute the corresponding diagnostic logic: if the current value continuously or suddenly exceeds the preset fault threshold (for example, continuously exceeding 200mA), it can be determined that the electromagnetic interference in high-voltage zone 2 is abnormally enhanced. Possible causes include abnormal arcing of the ATS switch, decreased insulation performance of a certain high-voltage component, etc.; if the current value suddenly drops to near zero, it can be determined that there is a fault in the shielding grounding loop, such as a broken grounding wire 10 or poor contact at its connection point with the metal isolation plate 9, resulting in the failure of the shielding function. Based on this assessment, the control system can immediately issue an alarm signal to prompt maintenance personnel to conduct repairs. This enables a low-cost fault early warning mechanism, allowing for the early detection of potential equipment failures and safety hazards, thereby improving the reliability and maintainability of the entire ATS switching cabinet.

[0048] In summary, this invention achieves significant technical benefits by dividing the ATS switching cabinet into four main modules: a high-voltage zone, a low-voltage zone, a communication zone, and an auxiliary and human-machine interface zone. It also employs a series of optimized designs, including a vertical layout of the high and low voltage zones, remote isolation of the communication zone, zoned outgoing ports, and grounding metal plate isolation. Firstly, it eliminates the interference path between high-voltage and low-voltage circuits and communication from a physical structural perspective, greatly improving the system's electromagnetic compatibility and operational reliability. Secondly, the modular layout and clear wiring zoning make installation, commissioning, and troubleshooting more organized, efficient, and convenient, reducing the overall lifecycle maintenance costs. Thirdly, the effective physical isolation between the high-voltage zone and other operating areas provides reliable safety for maintenance personnel. Finally, the standardized functional module design facilitates mass production and quality control, and reserves flexible expansion space for future functional upgrades.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
