Description

Technical Field

[0001] This invention relates to the field of low-voltage electrical technology, and in particular to a plug-in panel and a dual-bus electrical control device. Background Technology

[0002] Distribution boxes are located at the end of the power transmission system and are an important component of the power system. Currently, in domestic household electrical control systems (also known as distribution boxes), circuit breakers are installed and fixed using DIN rails. However, the DIN rails only serve as mounting brackets; additional wiring is required after the circuit breakers are installed before they can be used, making the power distribution operation cumbersome. Summary of the Invention

[0003] The main objective of this invention is to provide a plug-in panel and a dual-bus electrical control device, which aims to solve the problem of cumbersome power distribution operations caused by the need to wire the circuit breaker after it is connected to the panel in traditional distribution boxes.

[0004] To achieve the above objectives, the present invention proposes a plug-in panel, which includes a first bus and a second bus. The first bus includes an input terminal, a first output terminal, and a first busbar group. The input terminal is used to connect to an external power supply and includes at least two input components. The input terminal is connected to the first busbar group through a first circuit breaker. The first output terminal includes multiple first output components, which are used to connect to external electrical appliances. The first output components are connected to the first busbar group through a second circuit breaker. The second bus includes a second output terminal and a second busbar group, which are spaced apart from the first busbar group along a first direction. The second output terminal includes multiple second output components, which are used to connect to external electrical appliances. The second output components are connected to the second busbar group through a third circuit breaker.

[0005] In one embodiment, the plug panel further includes a converter, through which the first busbar group and the second busbar group are connected.

[0006] In one embodiment, the number of converters is at least two, one of which is a master converter and at least one of which is a redundant converter.

[0007] In one embodiment, the plug-in panel includes a connecting frame; the connecting frame, the first output component, and the second output component form a dual-output integrated module, wherein both the first output component and the second output component are connected to the connecting frame, and the first output component forms a first output wiring slot at one end of the connecting frame, and the second output component forms a second output wiring slot at the other end of the connecting frame; the connecting frame, the input component, and the second output component form an input-output integrated module, wherein both the input component and the second output component are connected to the connecting frame, and the input component forms an input wiring slot at one end of the connecting frame, and the second output component forms a second output wiring slot at the other end of the connecting frame.

[0008] In one embodiment, the connecting frame is provided with a first limiting groove group and a second limiting groove group at intervals along a first direction, the first busbar group is inserted into the first limiting groove group, and the second busbar group is inserted into the second limiting groove group.

[0009] In one embodiment, the connecting frame includes two limiting plates and a partition between the two limiting plates, with the partition forming an installation space between the partition and the two limiting plates respectively. The first limiting groove group is located at the bottom of one of the installation spaces, and the second limiting groove group is located at the bottom of the other installation space.

[0010] In one embodiment, the input component further includes an input terminal connected to the input wiring slot, the input terminal passing through the connecting frame and disposed on the same side as the first busbar group; the first output component further includes a first output terminal connected to the input wiring slot, the first output terminal passing through the connecting frame and disposed on the same side as the first busbar group; the second output component further includes a second output terminal connected to the input wiring slot, the second output terminal passing through the connecting frame and disposed on the same side as the second busbar group.

[0011] In one embodiment, the plug panel further includes a control board, on which connectors are provided. The control board is located at the bottom of the connection frame, and the connectors pass through the connection frame and are electrically connected to a second circuit breaker or a third circuit breaker.

[0012] In one embodiment, there are multiple control boards, and each control board corresponds to multiple first output components and / or multiple second output components.

[0013] In addition, the present invention also provides a dual-bus electrical control device, the dual-bus electrical control device including a first circuit breaker, a second circuit breaker, a third circuit breaker and a plug-in panel as described above, wherein the first circuit breaker is plugged into the first busbar group and correspondingly connects the input component and the first busbar group; the second circuit breaker is plugged into the first busbar group and correspondingly connects the first output component and the first busbar group; the third circuit breaker is plugged into the second busbar group and correspondingly connects the second output component and the second busbar group.

[0014] In the technical solution of this invention, the wiring work can be completed on the panel side, which provides the conditions for pre-wiring before the circuit breakers (first circuit breaker, second circuit breaker, and third circuit breaker) are connected to the panel. This allows the circuit breakers to be used with the plug-in panel, improving the convenience of the circuit breakers in the plug-in panel for installation and application. In addition, it not only eliminates the trouble of additional wiring after the circuit breakers are installed in the panel, but also simplifies the wiring of the distribution box by performing the wiring on the plug-in panel side.

[0015] Furthermore, the input current type of the input terminal and the output current type of the first and second output terminals can be configured according to different power consumption scenarios. Since the first and second output terminals output different currents respectively, they each serve as a current output bus, thus achieving dual-bus output. Attached Figure Description

[0040] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.

[0041] This invention proposes a plug-in panel and a dual-bus electrical control device, aiming to solve the problem of cumbersome power distribution operations caused by the need to wire the circuit breaker after the circuit breaker is connected to the panel in traditional distribution boxes.

[0042] like Figure 1 and Figure 2As shown, in one embodiment of the present invention, the plug-in panel 100 includes a first bus and a second bus. The first bus includes an input terminal 1, a first output terminal 2, and a first busbar group 3. The input terminal 1 is used to connect to an external power source and includes at least two input components 11. The input terminal 1 is connected to the first busbar group 3 through a first circuit breaker. The first output terminal 2 includes a plurality of first output components 21. The first output components 21 are used to connect to external electrical appliances and are connected to the first busbar group 3 through a second circuit breaker. The second bus includes a second output terminal 4 and a second busbar group 5. The second busbar group 5 and the first busbar group 3 are spaced apart along a first direction. The second output terminal 4 includes a plurality of second output components 41. The second output components 41 are used to connect to external electrical appliances and are connected to the second busbar group 5 through a third circuit breaker.

[0043] In this embodiment, input terminal 1, first output terminal 2, and first busbar group 3 (busbars ① and ②) are located on one side of the panel, and input terminal 1, first output terminal 2, and first busbar group 3 are used together as a first bus; second output terminal 4 and second busbar group 5 (busbars ③ and ④) are located on the other side of the panel, and second output terminal 4 and second busbar group 5 are used together as a second bus.

[0044] The first output component 21 and the second output component 41 have the same structure and are collectively referred to as output components. Specifically, input terminal 1 is composed of multiple input components 11, and the first output terminal 2 and the second output terminal 4 are each composed of multiple output components. Before the circuit breaker is connected to input terminal 1, the input components 11 can be pre-wired (i.e., connected to an external AC or DC power supply via power lines), so that the input components 11 can obtain AC current or DC current from the AC or DC power supply. When the external first circuit breaker is inserted into the position of input terminal 1, opening the first circuit breaker can electrically connect the input components 11 to the first busbar group 3, so that the AC current or DC current of the input components 11 can be input into the first busbar group 3. Conversely, opening the first circuit breaker will disconnect the input components 11 from the first busbar group 3.

[0045] Before the first output terminal 2 is connected to the second circuit breaker, the output components of the first output terminal 2 can be pre-wired (i.e. connected to external electrical appliances via power lines). When the second circuit breaker is inserted into the position of the first output terminal 2, opening the second circuit breaker can electrically connect the first output component 21 to the first busbar group 3, so that the first output component 21 can obtain AC current or DC current from the first busbar group 3 and transmit it to the electrical appliances for use via power lines.

[0046] Similar to the first output terminal 2, before the second output terminal 4 is connected to the circuit breaker, the output component of the second output terminal 4 can be pre-wired (i.e. connected to the external electrical appliance via the power line). When the third circuit breaker is inserted into the position of the second output terminal 4, opening the third circuit breaker can electrically connect the second output component 41 to the second busbar group 5, so that the second output component 41 can obtain AC current or DC current from the second busbar group 5 and transmit it to the electrical appliance for use via the power line.

[0047] In the plug-in panel 100 structure provided by the present invention, wiring can be completed on the panel side, which provides the conditions for pre-wiring before the circuit breakers (first circuit breaker, second circuit breaker, and third circuit breaker) are connected to the plug-in panel 100. This allows the circuit breakers to be used immediately with the plug-in panel 100, improving the convenience of the circuit breakers in the plug-in panel 100. In addition, it not only eliminates the trouble of additional wiring after the circuit breakers are installed in the panel, but also simplifies the wiring of the distribution box by wiring on the plug-in panel 100 side.

[0048] In one embodiment, the plug-in panel 100 further includes a converter 6, through which the first busbar group 3 and the second busbar group 5 are connected. The first busbar group 3 and the second busbar group 5 can be electrically connected by plugging in an external converter 6, which can convert the AC or DC current in the first busbar group 3 and input it into the second busbar group 5.

[0049] Input terminal 1 can be an AC (alternating current) or DC (direct current) input port; first output terminal 2 can be used as an AC or DC output port, and the same applies to second output terminal 4. In practical applications, the input current type of input terminal 1 and the output current type of the first / second output terminals can be configured according to different power consumption scenarios. Since the first / second output terminals output different currents, they each function as a current output bus, thus achieving dual-bus output in the aforementioned system.

[0050] Furthermore, the plug-in panel 100 of this invention can simultaneously adapt to multiple power usage scenarios. Depending on the requirements, the plug-in panel 100 can be configured to simultaneously support one of the following power usage scenarios: single-phase AC, three-phase AC, single DC, mixed DC (e.g., low-voltage and high-voltage DC mixed scenarios), or AC / DC combined. The number of power usage scenarios applicable to the plug-in panel 100 matches the number of output terminals. Through the above concept, the electrical control system using the plug-in panel 100, with its multiple output terminals, each serving as a current output bus, can adapt to various power usage scenarios, thus achieving the function of multi-bus current output.

[0051] Specifically, input terminal 1 is connected to mains power (220V / 380V AC) as an AC input terminal.

[0052] In the above case, if all converters 6 are AC / AC converters, then the first output terminal 2 and the second output terminal 4 are both AC outputs. The first output terminal 2 and the second output terminal 4 can be set as one of the following: single-phase AC output port, two-phase AC output port, and three-phase AC output port.

[0053] If all converters 6 are AC / DC converters 6, there are two possibilities:

[0054] ① The first output terminal 2 is an AC output, while the second output terminal 4 is a DC output. For example, one end outputs single-phase AC power and the other end outputs low-voltage DC power, realizing the function of AC and DC power usage.

[0055] ② Both the first and second output terminals are DC outputs, but the first and second output terminals output DC voltages of different voltages respectively. For example, one terminal outputs high voltage DC and the other terminal outputs low voltage DC (for example, outputting 375V and 48V DC respectively).

[0056] The working principle is as follows:

[0057] AC power is input to input terminal 1, which supplies AC power to the panel. Converter 6 draws AC power from the panel and performs current conversion. The converted current is then transmitted through the panel to the first and / or second output terminals, which output the converted current. Alternatively, in some cases, the AC input terminal may directly supply a portion of the AC power to the first output terminal 2 via the panel, while supplying the remaining portion to converter 6 via the panel for current conversion. The converted current is then transmitted through the panel to the second output terminal 4, which outputs the converted current.

[0058] To ensure stable operation and facilitate long-term current conversion, at least two converters 6 are used, with one converter 6 serving as the main converter and at least one converter 6 as a redundant converter. This means that at least two converters 6 employ a redundant design, ensuring that in actual use, at least one converter 6 acts as the main converter to convert the current input to the AC input terminal of the panel, while the remaining converters serve as redundant modules of the main converter. If the current main converter fails or is damaged, at least one of the redundant converters will actively switch to become the main converter for current conversion.

[0059] In one application scenario, the system is equipped with three converters 6, at least one of which serves as the primary converter and at least one as a redundant converter, and each converter 6 is an AC / DC converter. The first output terminal 2 is an AC output port, and the second output terminal 4 is a DC output port.

[0060] Please refer to the above. Figure 5 The first circuit breaker serves as the AC input terminal; the second circuit breaker serves as the AC output port; and the third circuit breaker serves as the DC output port.

[0061] The input terminal of the first circuit breaker is connected to the mains power, and the output terminal is connected to the panel; the input terminal of the second circuit breaker is connected to the panel, and the output terminal is connected to the AC appliance; the input port of the third circuit breaker is connected to the panel, and the output port is connected to the DC appliance; the AC / DC converter acts as a bridge connecting the first circuit breaker (i.e., the AC input terminal) and the third circuit breaker (i.e., the DC output port), with its input terminal connected to the output terminal of the first circuit breaker through the panel, and its output terminal connected to the input terminal of the third circuit breaker through the panel.

[0062] Furthermore, the first busbar group 3 serves as a connection structure between the AC input terminal and the first output terminal 2. The first busbar group 3 includes busbar ① and busbar ②, which are the live wire (L) and neutral wire (N) of the AC, respectively. The output port of the first circuit breaker located at the first input terminal 2, the input port of the second circuit breaker located at the first output terminal, the input port of the AC / DC converter, and the gateway are respectively connected to busbar ① and busbar ②.

[0063] The second busbar group 5 includes a connection structure between the AC input terminal and the second output terminal 4. The second busbar group 5 includes busbar ③ and busbar ④, which are the positive (+) and negative (-) terminals of DC, respectively. The input port of the third circuit breaker, the output port of the AC / DC converter 6, and the gateway located at the second output terminal 4 are connected to busbar ③ and busbar ④, respectively.

[0064] The input component 11 is provided with an input terminal 112 connected to its input port. The input port of the input component 11 can be connected to the power line of the mains power. The input terminal 112 of the input component 11 is connected to the input port of the first circuit breaker so that the mains power is input to the first circuit breaker through the input component 11. The first circuit breaker then inputs the mains power to the first busbar group 3 through its output port. After that, the second circuit breaker, the AC / DC converter 6 and the gateway can draw power from the first busbar group 3.

[0065] The DC output component (second output component 41) is provided with an output terminal (second output terminal (412)) connected to its output port. When the output terminal of the DC output component can be connected to the output port of the third circuit breaker, the output port of the DC output component is connected to the DC appliance. The AC / DC converter obtains AC power from the first busbar group 3, converts the AC power into DC power and outputs it to the second busbar group 5. The third circuit breaker obtains DC power from the second busbar group 5 through its input port and then outputs it to the DC output component through its output port. The DC output component outputs DC power to the DC appliance through its output port.

[0066] The AC output component (first output component 21) is provided with an output terminal (first output terminal (212)) connected to its output port. When the output terminal of the AC output component can be connected to the output port of the second circuit breaker, the output port of the AC output component is connected to the AC appliance. The second circuit breaker takes power from the first busbar group 3 through its input port and then outputs it to the AC output component through its output port. The AC output component outputs DC power to the AC appliance through its output port.

[0067] It should be noted that the aforementioned plug-in panel 100 is based on the premise that the first output terminal 2 is an AC output and the second output terminal 4 is a DC output. That is, this panel structure is designed for power supply scenarios where both AC and DC power are used. If the current type output from the first and second output terminals is changed, altering the power supply scenario, the types of the converter 6 and output components in the panel need to be adaptively modified according to the specific power supply scenario. For example:

[0068] Please refer to the above. Figure 6 It is also possible to have input terminal 1 as the AC input terminal, and the first and second output terminals as AC output terminals with different voltages. For example, the first output terminal 2 can be a 220VAC output terminal, while the second output terminal 4 can be a 380VAC output terminal. In this case, the panel needs to be equipped with an AC / AC converter or AC transformer.

[0069] Please refer to the above. Figure 7 Input terminal 1 is a DC input terminal, first output terminal 2 is a DC output terminal, and second output terminal 4 is an AC output terminal. For example, first output terminal 2 outputs 48V DC power, while second output terminal 4 outputs 220V AC power. In this case, the panel needs to be equipped with a DC / AC converter.

[0070] Please refer to the above. Figure 8 Input terminal 1 is a DC input terminal, and the first and second output terminals are both DC output terminals. For example, the first output terminal 2 is a 48V DC output terminal, while the second output terminal 4 is a 220V AC output terminal. In this case, the panel needs to be equipped with a DC / DC converter (or DC transformer).

[0071] In addition, regarding the plug-in panel 100 in the above embodiment, without changing the overall volume of the distribution box or the number of circuit breakers it can accommodate, the connection method of the busbar group can be changed by first disconnecting the line of any busbar group at a designated location, thereby adjusting the number of circuit breakers of different output types.

[0072] In one example, please refer to [see also] Figure 9 Without changing the position of input terminal 1, the second busbar group 5 can be disconnected. A portion of the disconnected second busbar group 5 continues to function as part of the DC output terminal, while the other portion connects to the AC output busbar at the AC connection position on the left, thus serving as part of the AC output terminal. This method allows for an increase in the number of circuit breakers at the AC output terminal to meet practical application needs. Alternatively, the input terminal can be positioned closer to converter 6, which will not be discussed in detail here.

[0073] In another example, please refer to [see also] Figure 10 The position of input terminal 1 is changed, and input terminal 1 is set on the side closer to converter 6; the first busbar group 3 can be disconnected. After being disconnected, part of the first busbar group 3 continues to serve as part of the AC output terminal, while the other part is connected to the busbar of the DC output terminal at the DC connection position on the left end to serve as part of the DC output terminal. In this way, the number of circuit breakers at the DC output terminal can be increased to meet the actual needs of use.

[0074] In one embodiment, please refer to [reference needed]. Figure 3 , Figure 4 and Figures 11 to 14 The plug-in panel 100 includes a connecting frame 7; the connecting frame 7, the first output component 21, and the second output component 41 form a dual-output integrated module 81. In the dual-output integrated module 81, both the first output component 21 and the second output component 41 are connected to the connecting frame 7, and the first output component 21 forms a first output wiring groove 211 at one end of the connecting frame 7, and the second output component 41 forms a second output wiring groove 411 at the other end of the connecting frame 7; the connecting frame 7, the input component 11, and the second output component 41 form an input-output integrated module 82. In the input-output integrated module 82, both the input component 11 and the second output component 41 are connected to the connecting frame 7, and the input component 11 forms an input wiring groove 111 at one end of the connecting frame 7, and the second output component 41 forms a second output wiring groove 411 at the other end of the connecting frame 7.

[0075] The connection frame 7 can connect the input component 11 and the second output component 41 opposite to the input component 11 into an input-output integrated module 82. The connection frame 7 can also connect the first output component 21 and the second output component 41 opposite to the first output component 21 into a dual-output integrated module 81. Through the configuration of the connection frame 7, multiple dual-output integrated modules 81 can be sequentially connected after the input-output integrated module 82 to jointly form a structure with a single input port and multiple output ports.

[0076] In one embodiment, the input component 11 further includes an input terminal 112 connected to the input wiring slot 111, the input terminal 112 passing through the connecting frame 7 and disposed on the same side as the first busbar group 3; the first output component 21 further includes a first output terminal 212 connected to the input wiring slot 111, the first output terminal 212 passing through the connecting frame 7 and disposed on the same side as the first busbar group 3; the second output component 41 further includes a second output terminal 412 connected to the input wiring slot 111, the second output terminal 412 passing through the connecting frame 7 and disposed on the same side as the second busbar group 5.

[0077] Each input component 11 includes an input wiring slot 111 and an input terminal 112 connected to the input wiring slot 111. The input wiring slot 111 is used to connect to the power line of an external power source. When the power source is AC power, the input wiring slot 111 of one input component 11 is used to connect to the live wire (L) of the AC power source and can be connected to busbar ① through a circuit breaker connected thereto. The input wiring slot 111 of the other input component 11 is used to connect to the neutral wire (N) of the AC power source and can be connected to busbar ② through a circuit breaker connected thereto. This configuration can establish an AC circuit on the first busbar group 3. Of course, when the power source is DC power, the wiring principle is similar to the above, and will not be described in detail here.

[0083] In one embodiment, cleaning is described in detail below. Figure 4 The plug-in panel 100 also includes a control board 9, on which connectors 91 are mounted. The control board 9 is located at the bottom of the connecting frame 7. The connectors pass through the connecting frame 7 and can be electrically connected to the second or third circuit breaker. Each connector 91 has four connection contacts, which can be connected to the four connecting springs of the low-voltage part of the circuit breaker, respectively. Two of the connection contacts act as electronic control switches to control the circuit breaker's operation.
