Description

Technical Field

[0001] This invention relates to the field of power distribution cabinet technology, and in particular to an integrated intelligent switch and power distribution cabinet. Background Technology

[0002] Existing power distribution cabinets contain numerous peripheral circuits, resulting in complex wiring connections and significant space consumption. These cabinets typically consist of multiple units, each with a frame, a conventional switch within the frame, and various copper busbars for switching. The power switching device then connects to the main busbar of the entire distribution cabinet, creating a complex and bulky peripheral circuit structure, leading to a highly intricate internal and external wiring configuration.

[0003] Furthermore, the market offers a wide variety of traditional switches, each with its own standards. Therefore, when manufacturing distribution cabinets, corresponding peripheral circuits need to be designed for each type of switch, resulting in a vast array of traditional switches and peripheral circuits. This significantly increases production costs and raises the question of reliability. Simultaneously, the complexity of the wiring within the distribution cabinet increases the number of connection points, thereby increasing potential failure points and the likelihood of malfunctions during subsequent use. This makes maintenance inconvenient and compromises safety performance. These issues with distribution cabinets incorporating traditional switches have plagued technicians for many years. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an integrated intelligent switch, breaking through the traditional thinking of power distribution cabinets with traditional switches, thereby improving the space utilization and usage rate of the switch in the power distribution cabinet.

[0005] To address the above problems, the present invention provides:

[0006] An integrated smart switch includes:

[0007] The outer casing has retractable adapters on both sides; the adapters are used to connect the main busbar and terminals on the distribution cabinet.

[0008] The switching module is used to control the on / off state of the integrated intelligent switch;

[0009] The main control module is used to control the operation of the integrated intelligent switch; the main control module is electrically connected to the opening and closing module and the adapter respectively;

[0010] The main control module includes an electrically connected controller and a functional module, the functional module being used to detect and protect the integrated smart switch;

[0011] The main control module and the circuit breaker opening and closing module are located inside the housing.

[0012] Furthermore, the functional module includes a relay protection module and an energy measurement module, which are electrically connected to the controller.

[0013] Furthermore, the functional module also includes a temperature measurement module, which is electrically connected to the controller.

[0014] Furthermore, a connecting rod is rotatably mounted inside the housing, and the adapter is connected to the connecting rod in a transmission manner; when the connecting rod rotates, it is used to drive the adapter to extend out of the housing or retract into the housing.

[0015] Furthermore, a mechanical locking assembly is connected between the connecting rod and the opening / closing module; the mechanical locking assembly is used to release the locking of the connecting rod when the opening / closing module is in the open state, so that the connecting rod can drive the adapter to move relative to the housing.

[0016] Furthermore, a locking element is provided on the connecting rod; a corresponding locking hole is provided on the opening and closing module, and the locking element is inserted into the locking hole to lock the position of the opening and closing module inside the housing.

[0017] Furthermore, the locking element is connected to the connecting rod via a transmission; when the connecting rod rotates, it drives the locking element to move closer to or away from the opening and closing module.

[0018] Furthermore, the adapter can move along the axial direction of the connecting rod to avoid structural errors between the integrated intelligent switch and the distribution cabinet.

[0019] Furthermore, the adapter includes an insulated clamping arm and a conductor located between the clamping arms; the clamping arm is used to fix the main busbar and wiring terminals on the distribution cabinet; the conductor is electrically connected to the main control module.

[0020] The present invention also provides a power distribution cabinet, including the aforementioned integrated intelligent switch.

[0021] The beneficial effects of this invention are as follows: The integrated intelligent switch provided by this invention integrates a switching module, a controller, and a functional module. The functional module realizes the detection and protection of the integrated intelligent switch, thereby enabling the integrated intelligent switch to have multiple functions. Simultaneously, the integrated intelligent switch provided by this invention can be directly connected to the main busbar and terminals in the distribution cabinet. Therefore, when installing the distribution cabinet, there is no need to equip the integrated intelligent switch with complex external circuits, thus avoiding the need for complex circuit layout design within the distribution cabinet and reducing costs.

[0039] Example 1

[0040] like Figures 1 to 4 As shown, the embodiment provides an integrated intelligent switch for installation in a power distribution cabinet, used for opening and closing circuits, controlling circuits, and providing circuit protection for the power receiving equipment connected to the power distribution cabinet.

[0041] The integrated smart switch includes a housing 100, a circuit breaker module 300, and a main control module 200. Both the circuit breaker module 300 and the main control module 200 are located inside the housing 100. The circuit breaker module 300 is located near the front panel of the housing 100, and its unlocking end passes through the front panel of the housing 100 to communicate with the outside world, making it convenient for operators to operate the circuit breaker module 300, thereby realizing the circuit connection or disconnection of the integrated smart switch.

[0042] The circuit breaker module 300 is used to control the on / off state of the integrated smart switch, that is, to control whether the circuit in the integrated smart switch is connected. The main control module 200 is electrically connected to the circuit breaker module 300; the main control module 200 is used to control the operation of the integrated smart switch.

[0043] The main control module 200 includes a controller 201 and a functional module electrically connected to each other; the controller 201 is electrically connected to the opening and closing module 300. The controller 201 is used to coordinate the operation of the various electronic components within the integrated intelligent switch. The functional module is used to detect and protect the internal operating status of the integrated intelligent switch.

[0044] Both sides of the outer casing 100 are provided with retractable adapters 500, which are used to connect the main busbar 801 and the terminal block 802 on the power distribution cabinet. The side wall of the outer casing 100 is provided with corresponding sliding grooves 101 through which the adapters 500 pass, thereby facilitating the adapters 500 to extend out of or retract into the outer casing 100. The adapters 500 are electrically connected to the main control module 200 via wires.

[0045] When the adapter 500 extends out of the housing 100, it connects the main busbar 801 and the terminal block 802 on the distribution cabinet, enabling a direct connection between the integrated smart switch and the main busbar 801 and the terminal block 802. Therefore, no connecting copper busbars are needed in the distribution cabinet, reducing connection points and lowering costs. When the adapter 500 retracts into the housing 100, the connection between the integrated smart switch and the main busbar 801 and the terminal block 802 can be disconnected.

[0046] In practical use, when the integrated intelligent switch is installed in the distribution cabinet, the adapter 500 extends out of the housing 100 and connects directly to the main busbar 801 and the terminal block 802; there is no need to equip the integrated intelligent switch with complex auxiliary adapter circuits such as adapter copper busbars in the distribution cabinet. This reduces the use of adapter copper busbars, lowering costs; at the same time, reducing the setup of external circuits reduces intermediate connection points, thereby reducing potential failure points and the possibility of subsequent malfunctions, facilitating later maintenance.

[0047] Because integrated smart switches incorporate corresponding functional modules, they can be directly monitored and protected without requiring external protection circuits in the distribution cabinet. This integrates the switching and auxiliary functions. Simultaneously, it reduces the need for external auxiliary circuits and wiring layout design, thereby minimizing the space occupied by external circuits in the distribution cabinet. Furthermore, it improves the space occupied by the integrated smart switch within the distribution cabinet, facilitates heat dissipation, and ensures optimal performance.

[0048] Example 2

[0049] like Figures 1 to 4 As shown, based on Embodiment 1, the functional modules further include a relay protection module 202, a temperature measurement module 203, and an energy measurement module 204; the relay protection module 202, the temperature measurement module 203, and the energy measurement module 204 are electrically connected to the controller 201. In this embodiment, the relay protection module 202, the temperature measurement module 203, and the energy measurement module 204 can be integrated on the same control circuit board.

[0050] The relay protection module 202 is used to detect faults or abnormalities occurring in the internal circuit of the integrated smart switch and issue an alarm signal; or the relay protection module 202 can directly isolate or disconnect the faulty part in the internal circuit of the integrated smart switch, thereby avoiding greater accidents or losses in the future.

[0051] The temperature measurement module 203 is used to detect the temperature inside the integrated smart switch and feed the measurement data back to the controller 201; the controller 201 is also connected to an alarm module 208; when the temperature inside the integrated smart switch is abnormal, the controller 201 controls the alarm module 208 to issue an alarm reminder so that staff can promptly detect and take corresponding measures.

[0052] The power measurement module 204 is used to detect the power output of the integrated smart switch per unit time. The power measurement module 204 is connected to a display module 205, which displays the power data detected by the power measurement module 204. A motor drive module 206 is connected between the display module 205 and the power measurement module 204; the motor drive module 206 and the power measurement module 204 are electrically connected via wires; the output terminal of the motor drive module 206 is connected to the pointer of the display module 205, and the motor drive module 206 drives the pointer to swing. After receiving the power data sent by the power measurement module 204, the motor drive module 206 drives the pointer of the display module 205 to swing to the corresponding position, displaying the corresponding power data. The motor drive module 206 is electrically connected to a motor protection module 207, which protects the operation of the motor drive module 206 and prevents damage to the motor drive module 206 due to factors such as current / voltage issues in the working circuit.

[0053] In some other embodiments, the functional module may also integrate other functional protection devices such as overvoltage protection.

[0054] Furthermore, in this embodiment, the adapter 500 has a pair of symmetrical clamping arms 501 at one end near the outer side of the housing 100; a clamping groove 502 is formed between the two clamping arms 501 to clamp the main busbar 801 or the terminal block 802, thereby fixing the adapter 500 to the main busbar 801 and the terminal block 802. The clamping arms 501 are made of flexible insulating material; a conductor (not shown in the figure) is provided at the bottom of the groove 502, and the conductor is electrically connected to the main control module 200 through a wire. When the adapter 500 is connected to the main busbar 801 or the terminal block 802, the corresponding conductor makes contact with the main busbar 801 or the terminal block 802 to achieve power transmission. When the adapter 500 is retracted into the housing 100, the conductor is separated from the main busbar 801 or the terminal block 802, thereby disconnecting the integrated smart switch from the main busbar 801 or the terminal block 802.

[0055] In this invention, the adapter 500 is configured as a retractable structure, providing a clear disconnection point between the adapter 500 and the main busbar 801 or terminal block 802, thereby improving operational safety. Simultaneously, it provides protection when the integrated intelligent switch is installed in the distribution cabinet, preventing damage caused by forceful insertion or impact.

[0056] In this embodiment, a connecting rod 400 is provided inside the outer casing 100; the connecting rod 400 is rotatably connected inside the outer casing 100; one end of the connecting rod 400 extends out of the front panel of the outer casing 100 and communicates with the outside, thereby facilitating the rotation of the connecting rod 400 by the operator.

[0057] In this embodiment, a connecting rod 400 is provided on each of the two sides of the interior of the outer casing 100; the connecting rod 400 is located near the adapter 500. One end of the adapter 500 near the interior of the outer casing 100 is connected to the connecting rod 400 in a transmission manner; when the connecting rod 400 rotates, it is used to drive the adapter 500 to extend out of the outer casing 100 or retract into the outer casing 100.

[0058] Four adapters 500 are respectively provided on both sides of the housing 100; the four adapters 500 on each side are connected to the same connecting rod 400, and the same connecting rod 400 simultaneously drives the four adapters 500 to achieve extension and retraction, thereby realizing the complete disconnection or connection of the integrated intelligent switch with the main busbar 801 or the terminal block 802.

[0059] In some other embodiments, the outer casing 100 may also be provided with three, five, six or other numbers of adapters 500 on both sides as needed.

[0060] In this embodiment, the adapter 500 and the connecting rod 400 can be connected by a gear and chain drive assembly, a gear drive assembly, or other components.

[0061] During use, operators can rotate the connecting rod 400 to extend the adapter 500 out of the housing 100 or retract the adapter 500 into the housing 100, thereby connecting or disconnecting the integrated smart switch from the main busbar 801 and the terminal block 802.

[0062] In this embodiment, the adapter 500 is movable along the axial direction of the connecting rod 400 to avoid structural errors between the integrated intelligent switch and the distribution cabinet. That is, the position of the adapter 500 is adjustable in the axial direction of the connecting rod 400, thereby preventing the integrated intelligent switch and the distribution cabinet from being unable to assemble due to structural errors. The width of the sliding groove 101 on the housing 100 is greater than the width of the adapter 500, thus facilitating smooth extension and retraction of the adapter 500 during position adjustment.

[0063] like Figures 4 to 6 As shown in the embodiment, a mechanical locking assembly 7 is connected between the connecting rod 400 and the opening / closing module 300; the mechanical locking assembly 7 is used to release the locking of the connecting rod 400 when the opening / closing module 300 is in the open state, so that the connecting rod 400 can drive the adapter 500 to move relative to the housing 100, that is, extend out of the housing 100 or retract into the housing 100.

[0064] When the circuit breaker module 300 is in the closed state, the connecting rod 400 is locked, preventing the operator from rotating the connecting rod 400 and thus preventing the adapter 500 from moving. This prevents the adapter 500 from connecting or disconnecting from the main busbar 801 or terminal block 802 when the internal circuit of the integrated smart switch is in operation, thereby preventing sudden power on / off of the integrated smart switch and potential damage; it also ensures the safety of the operator.

[0065] In this embodiment, the mechanical locking assembly 7 includes a fixed clamping arm 701, a rotating clamping arm 702, and a pull cable 703. The fixed clamping arm 701 is fixedly installed on the inner wall of the housing 100, and the rotating clamping arm 702 is rotatably connected to the fixed clamping arm 701. One end of the pull cable 703 is connected to the opening and closing module 300, and the other end of the pull cable 703 is connected to the rotating clamping arm 702. When the pull cable 703 is tightened, it pulls one end of the rotating clamping arm 702 closer to the fixed clamping arm 701 to achieve a clamping action. When the pull cable 703 is loosened, the rotating clamping arm 702 moves away from the fixed clamping arm 701. The connecting rod 400 is located between the clamping end of the fixed clamping arm 701 and the clamping end of the rotating clamping arm 702. Thus, the connecting rod 400 can be fixed by the fixed clamping arm 701 and the rotating clamping arm 702 when clamping.

[0066] In use, when the circuit breaker module 300 is closed, the pull cable 703 is tightened, locking the connecting rod 400. When the circuit breaker module 300 is open, the pull cable 703 is released, releasing the lock on the connecting rod 400. This achieves an interlocking connection between the circuit breaker module 300 and the connecting rod 400.

[0067] Of course, in some other embodiments, other mechanical interlocking structures may be used between the opening and closing module 300 and the connecting rod 400.

[0068] In this embodiment, a locking element 401 is provided on the connecting rod 400 to lock the position of the circuit breaker module 300 within the housing 100; locking holes 301 are correspondingly provided on both sides of the circuit breaker module 300; the locking element 401 is inserted into the locking holes 301 to lock the position of the circuit breaker module 300 within the housing 100. The circuit breaker module 300 can be pulled out or inserted into the housing 100; when the circuit breaker module 300 is inserted into the housing 100, the locking element 401 is operated to lock the circuit breaker module 300, fixing its relative position within the housing 100. This prevents the circuit breaker module 300 from moving freely relative to the housing 100, ensuring that operators can smoothly operate the circuit breaker module 300 during subsequent work.

[0069] In this embodiment, the locking member 401 and the connecting rod 400 are connected by a toothed engagement. Specifically, the surface of the connecting rod 400 where it connects to the locking member 401 is provided with teeth, making the connecting rod 400 gear-like. The locking member 401 has a toothed surface, realizing the meshing connection between the connecting rod 400 and the locking member 401. Thus, when the connecting rod 400 rotates, it pushes the locking member 401 to move closer to or further away from the opening and closing module 300.

[0070] After the integrated intelligent switch is installed in the distribution cabinet, when staff need to install or remove the switching module 300 from the integrated intelligent switch, because both the main busbar 801 and the terminal block 802 are energized, the adapter 500 needs to be disconnected from the main busbar 801 or the terminal block 802 to ensure that the integrated intelligent switch is powered off before staff can open the integrated intelligent switch to install or remove the switching module 300. This prevents electric shock to staff and ensures their safety.

[0071] In existing technologies, the determination of whether a switch is de-energized is mainly based on manual observation, which poses significant safety hazards. This invention, however, incorporates a locking element 401 and a locking hole 301 for coordinated use, establishing an interlocking relationship between the adapter 500 and the switching module 300. This ensures that the integrated smart switch can only be opened and the switching module 300 inserted or removed when the power is off, thus ensuring operator safety.

[0072] In use, the mechanical locking assembly 7 and locking element 401 provided in this invention ensure that the operator can only operate in a set sequence, thereby ensuring the safety of the operator.

[0073] like Figure 7 As shown in the embodiment, the integrated smart switch further includes a communication interface 600, which is connected to the main control module 200; the communication interface 600 is disposed on the side wall of the housing 100. The communication interface 600 is used to connect data cables and other wires to realize wired communication between the integrated smart switch and peripheral devices.

[0074] Of course, in some other embodiments, the integrated smart switch may also be equipped with a wireless communication module to realize wireless communication connection between the integrated smart switch and peripheral devices.

[0075] The rear panel of the housing 100 is also provided with heat dissipation holes 102 to facilitate heat dissipation of the integrated smart switch and prevent the internal temperature of the integrated smart switch from being too high and damaging the electronic components during operation.

[0076] like Figure 8 As shown, in the prior art, auxiliary electronic components need to be installed in the distribution cabinet during production to facilitate the later installation of a power switching device. This power switching device is a traditional switch that performs switching functions. Configuring the auxiliary electronic components requires extensive wiring within the distribution cabinet, thus occupying space and compressing the space available for the power switching device. Furthermore, the prior art requires the design of transition copper busbars within the distribution cabinet to connect the switching device to the main busbar 801 and terminal blocks 802; these transition copper busbars also occupy significant space and increase costs. Therefore, the limited space occupied by the power switching device within the distribution cabinet results in slow heat dissipation during subsequent operation, leading to a rapid increase in internal temperature and reduced performance. Moreover, the design of the auxiliary electronic components and the transition copper busbars requires adaptability design based on the power switching device being used, preventing the standardization and uniformity of distribution cabinet production.

[0077] like Figure 9As shown, the integrated smart switch provided in this invention integrates a main control module 200 within the switch itself. This main control module 200 includes functional modules. Therefore, when installing the integrated smart switch into a distribution cabinet, there is no need for external auxiliary electronic device design, eliminating the need for wiring connections. Furthermore, the integrated smart switch in this invention uses a retractable adapter 500 to directly connect the main busbar 801 and the terminal block 802, eliminating the need for adapter copper busbars in the distribution cabinet and further reducing the space occupied within the cabinet; thus, the size of the integrated smart switch can be increased. Simultaneously, the reduced number of connection points in the distribution cabinet decreases the number of potential failure points, lowering the likelihood of subsequent malfunctions. In addition, installing the integrated smart switch of this invention eliminates the need for various auxiliary peripheral circuit adaptation designs during the production of distribution cabinets, thus achieving standardization and uniformity in distribution cabinet production and reducing production costs.

[0078] The integrated smart switch of this invention can be made with a large volume space, such as a flat cuboid shape, to accelerate the heat dissipation of the integrated smart switch and improve its working performance.

[0079] Example 3

[0080] The embodiment also provides a power distribution cabinet, including a main body of the power distribution cabinet, in which the integrated intelligent switch is disposed. A main busbar 801 and a terminal block 802 are respectively disposed on both sides of the power distribution cabinet; the integrated intelligent switch is electrically connected to the main busbar 801 and the terminal block 802 through the adapters 500 on both sides.

[0081] During the installation of the distribution cabinet, the adapter 500 of the integrated intelligent switch is retracted into the housing 100, and then the integrated intelligent switch is pushed into the main body of the distribution cabinet. After the integrated intelligent switch is installed in place, the connecting rods 400 on both sides of the integrated intelligent switch are rotated to connect the adapter 500 to the main busbar 801 and the terminal block 802. Then, the switching module 300 can be operated to connect the power supply to the internal circuit of the integrated intelligent switch, allowing it to begin operation.
