DETAILED DESCRIPTION

[0041] In order to make the purpose, technical scheme and advantages of the embodiments of the present invention clearer, the technical scheme in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0042] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present application.

[0043] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0044] In addition, the terms “first”, “second”, etc., if used, are merely used to distinguish between the descriptions and should not be understood as indicating or implying relative importance.

[0045] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0046] In order to improve resource utilization of a circuit breaker device, the present application provides a circuit breaker device and a circuit breaker control method.

[0047] A circuit breaker device provided in an embodiment of the present application is explained below through a specific example. Figure 1 This is a schematic diagram of the structure of a circuit breaker device provided in an embodiment of the present application. Figure 1 As shown, the circuit breaker device includes: a plurality of circuit breakers 1, at least one control board 2, a power board 3 and a communication board 4.

[0048] The plurality of circuit breakers 1 are connected to a preset AC power source, and the power board 3 is connected to a preset AC power source. For example, the preset AC power source may be a mains supply.

[0049] Each control board 2 is connected to at least two circuit breakers 1 , and at least one control board 2 is connected to a communication board 4 ; at least one control board 2 and a communication board 4 are connected to a power supply board 3 .

[0050] One end of the multiple circuit breakers 1 is connected to a preset AC power source, and the other end of the multiple circuit breakers 1 is connected to the power load. A multi-pole circuit breaker is formed, which constitutes a multi-pole power line. On this basis, only one power board 3 is set, and the power board 3 draws power from the preset AC power source.

[0051] At least two circuit breakers 1 are connected via a control panel 2, which can collect information from the circuit breakers 1 and control the circuit breakers 1, thereby achieving efficient control and saving resources of the control panel 2. Among them, a control panel 2 is detachably connected to at least two circuit breakers 1, and the circuit breakers 1 can be increased or decreased according to actual needs, which is convenient for the expansion of the circuit breaker device.

[0052] At least one control board 2 is connected to the communication board 4, and the control boards 2 can exchange information with each other, and can also send the information of the circuit breaker 1 collected by the control board 2 and the control information of the circuit breaker 1 to the terminal device (for example, a mobile phone, a tablet computer) through the communication board 4. The terminal device can also send pre-configured information (for example, protection parameters of the circuit breaker 1) to the control board 2 through the communication board 4, so that the control board 2 can control the circuit breaker 1. Setting up a communication board 4 also saves the resources of the communication board 4.

[0053] For example, if there are twelve circuit breakers 1 that need to be controlled, four control boards 2 can be configured, and one control board 2 controls three circuit breakers 1. And only one power board 3 and one communication board 4 need to be configured. The number of poles of the circuit breaker 1 can also be expanded according to actual needs to reduce resource waste. The circuit breaker 1, control board 2, power board 3 and communication board 4 are all separately set and connected by wires in a box, which saves physical space and reduces the replacement and maintenance costs after a failure.

[0054] For example, copper busbars may be used to implement all of the above connections.

[0055] In summary, in this embodiment, the circuit breaker device includes: multiple circuit breakers, at least one control board, a power board and a communication board; multiple circuit breakers are connected to a preset AC power source, and the power board is connected to a preset AC power source; each control board is connected to at least two circuit breakers, and at least one control board is connected to a communication board; at least one control board and a communication board are connected to the power board. Thus, efficient control is achieved, resources, costs and physical space are saved, and replacement and maintenance are facilitated.

[0056] In the above Figure 1 On the basis of the corresponding embodiments, the embodiments of the present application further provide a circuit breaker. Figure 2A schematic diagram of the structure of a circuit breaker provided in an embodiment of the present application. Figure 2 As shown, each circuit breaker includes a switch mechanism 11 , an execution unit 12 , a sensor 13 and an adapter plate 14 .

[0057] The execution unit 12 and the sensor 13 are both connected to the adapter board 14; the adapter board 14 is also connected to the control board 2; the switch mechanism 11 is mechanically connected to the execution unit 12; and the switch mechanism 11 is connected to a preset AC power supply.

[0058] The sensor 13 obtains the sensing signal of the sensor 13, and transmits the sensing signal to the control board 2 through the adapter board 14. The control board 2 transmits the control signal to the execution unit 12 through the adapter board 14. The execution unit 12 controls the switch mechanism 11 (closing / opening) according to the control signal.

[0059] For example, the sensor 13 may be a current transformer (or shunt), a temperature sensor, a zero-sequence current transformer, a handle position sensing switch, etc. The switch mechanism 11 is composed of a gear and a connecting rod.

[0060] By providing the adapter plate 14, the wiring inside the circuit breaker 1 is made clearer, which saves wiring resources and facilitates later maintenance.

[0061] In summary, in this embodiment, each circuit breaker includes: a switch mechanism, an execution unit, a sensor, and an adapter board; the execution unit and the sensor are both connected to the adapter board; the adapter board is also connected to the control board; the switch mechanism is mechanically connected to the execution unit; and the switch mechanism is connected to a preset AC power supply. Thus, wiring resources are saved and later maintenance is facilitated.

[0062] In the above Figure 2 Based on the corresponding embodiment, the embodiment of the present application also provides another circuit breaker. Figure 3 This is a schematic diagram of the structure of another circuit breaker provided in an embodiment of the present application. Figure 3 As shown, each circuit breaker further includes: a storage unit 15 , which is disposed on the adapter board 14 and connected to the control board 2 .

[0063] The storage unit 15 is used to store calibration parameters of the sensor 13, and store specification information, function information, default protection parameters, etc. of the circuit breaker 1. For example, the storage data in the storage unit 15 is pre-stored by the user.

[0064] When adding a circuit breaker 1, the control board 2 can obtain information parameters of the circuit breaker 1 in a timely manner through the storage unit 15, and send the information parameters to the terminal device through the communication board 4 to display them to the user.

[0065] In summary, in this embodiment, each circuit breaker further includes: a storage unit, which is arranged on the adapter board and connected to the control board. Thus, information parameters of the circuit breaker can be obtained through the storage unit.

[0066] In the above Figure 2 On the basis of the corresponding embodiments, the embodiments of the present application also provide another circuit breaker. Figure 4 A schematic diagram of the structure of another circuit breaker provided in an embodiment of the present application.

[0067] like Figure 4 As shown, the circuit breaker module further includes: an indication unit 16 ; the indication unit 16 is connected to the control board 2 via the adapter board 14 .

[0068] When the control panel 2 controls the execution unit 12 to close / open the switch mechanism 11 , it can also control the indication unit 16 to give indications. The state of the switch mechanism 11 can be known through the indication signal of the indication unit 16 .

[0069] For example, the indicating unit 16 may be an LED light. The LED light goes out when the switch mechanism 11 is closed, and the LED light stays on / flashes when the switch mechanism 11 is opened.

[0070] In summary, in this embodiment, the circuit breaker module further includes: an indication unit; the indication unit is connected to the control board via the adapter board, so as to accurately indicate the circuit breaker status.

[0071] In the above Figure 1 Based on the corresponding embodiments, the embodiments of the present application also provide a control panel. Figure 5 A schematic diagram of the structure of a control panel provided in an embodiment of the present application.

[0072] like Figure 5 As shown, the control board 2 is provided with: a control unit 21 , a processing unit 22 , and a sampling unit 23 .

[0073] The sampling unit 23 is connected to at least two circuit breakers 1 , and the sampling unit 23 is connected to the processing unit 22 ; the processing unit 22 is connected to the control unit 21 , and the control unit 21 is connected to at least two circuit breakers 1 , and the control unit 21 is connected to the communication board 4 .

[0074] The sampling unit 23 obtains the sensor signal transmitted by the sensor 13 through the adapter board 14, and transmits the sensor signal to the processing unit 22. The processing unit 22 processes the sensor signal and the protection parameter of the circuit breaker 1 to obtain a processing result, and transmits the control instruction corresponding to the processing result to the control unit 21. The control unit 21 transmits the control signal to the execution unit 12 through the adapter board 14 according to the control instruction, so that the execution unit 12 performs the closing / opening operation on the switch mechanism 11.

[0075] The control panel 2 is designed in a modular manner, and the control unit 21, the processing unit 22 and the sampling unit 23 are detachably connected to facilitate subsequent maintenance.

[0076] In summary, in this embodiment, the control board is provided with: a control unit, a processing unit, and a sampling unit; the sampling unit is connected to at least two circuit breakers, and the sampling unit is connected to the processing unit; the processing unit is connected to the control unit, and the control unit is connected to at least two circuit breakers, and the control unit is connected to the communication board. Thus, control board resources are saved and later maintenance is facilitated.

[0077] Based on the above embodiments, multiple circuit breakers 1 in the embodiments of the present application are arranged in the first area of ​​a preset shell, and at least one control board 2, power board 3 and communication board 4 are arranged in a second area of ​​the preset shell away from the first area.

[0078] For example, the first area may be an upper space area inside a preset shell, and the second area may be a lower space area inside the preset shell.

[0079] The control board 2, power board 3 and communication board 4 are arranged in the same area. Multiple circuit breakers 1 are arranged in another area. Multiple circuit breakers 1 can share the control board 2, power board 3 and communication board 4 in the second area, which has high resource utilization. The layered layout makes reasonable use of different areas of the preset shell space without occupying additional space, which improves space utilization.

[0080] In summary, in this embodiment, multiple circuit breakers are arranged in the first area of ​​the preset housing, and at least one control board, power board, and communication board are arranged in the second area of ​​the preset housing away from the first area. Thus, different areas of the preset housing space are reasonably utilized without occupying additional space, thereby improving space utilization.

[0081] Based on the above embodiments, multiple circuit breakers 1 in the embodiments of the present application are arranged in a strong current connection module in the first area; at least one control board 2, power board 3 and communication board 4 are integrated in the base in the second area.

[0082] At least one control board 2, power board 3 and communication board 4 are integrated into the base in the second area to form an intelligent base, which facilitates the detachable connection of multiple circuit breakers 1 on the base, facilitates the adjustment of the number of circuit breakers in the circuit breaker device, and improves the working efficiency of the circuit breaker device.

[0083] The strong current connection module realizes the connection between strong current indoor and outdoor. The electric energy transmitted to the control board 2 and the communication board 4 through the power board 3 is weak current. There are no strong current components or only a small number of analog components inside the circuit breaker 1. When conducting EMC tests, the required protection devices are concentrated in the base, reducing the repeated waste of resources and saving costs and space.

[0084] In summary, in this embodiment, multiple circuit breakers are arranged in the strong current connection module in the first area; at least one control board, power board and communication board are integrated in the base in the second area. Thus, it is convenient to adjust the number of circuit breakers in the circuit breaker device, and improve the working efficiency of the circuit breaker device.

[0085] On the basis of the above-mentioned embodiment, in the embodiment of the present application, a plurality of circuit breakers 1 are plugged and unplugged and connected to the base in the second area.

[0086] When multiple circuit breakers 1 are detachably connected to the base in the second area, they can be connected in a plug-in connection manner.

[0087] By pre-arranging the line routing in the circuit breaker device, when the circuit breaker 1 is plugged in or out of the base in the second area, the connection relationship between the circuit breaker 1 and the control board 2 and the power board 3 can be achieved.

[0088] In summary, in this embodiment, a plurality of circuit breakers are plugged and unplugged into the base in the second area, thereby improving the working efficiency of the circuit breaker device.

[0089] A circuit breaker control method provided in an embodiment of the present application is explained below through a specific example. Figure 6 The flowchart of a circuit breaker control method provided in an embodiment of the present application is shown in FIG. The method is applied to any control board in the circuit breaker device in any of the above embodiments. Figure 6 As shown, the method includes:

[0090] S101. Acquire detection signals of at least two circuit breakers.

[0091] Detection signals of at least two circuit breakers are obtained through sensors and adapter plates.

[0092] For example, the detection signal of the circuit breaker may be: handle position information, voltage and current information, leakage information, etc. of each pole circuit breaker.

[0093] S102: Determine whether detection signals of at least two circuit breakers meet preset protection conditions.

[0094] The preset protection condition is whether the detection signal exceeds the protection parameter of the detection signal.

[0095] For example, if the detection signal is a current signal, the protection parameter is a current threshold value of current overcurrent, and the preset protection condition is that the actual measured current value of the circuit breaker exceeds the current threshold value of current overcurrent.

[0096] S103: If a first circuit breaker among the at least two circuit breakers meets a preset protection condition, control the first circuit breaker to perform a tripping operation to protect the first circuit breaker.

[0097] If the first circuit breaker among the at least two circuit breakers meets the preset protection condition, it indicates that the first circuit breaker has a risk, and the first circuit breaker is controlled to perform a tripping operation to protect the first circuit breaker.

[0098] In summary, in this embodiment, detection signals of at least two circuit breakers are obtained; it is determined whether the detection signals of at least two circuit breakers meet the preset protection conditions; if the first circuit breaker among the at least two circuit breakers meets the preset protection conditions, the first circuit breaker is controlled to perform a tripping operation to protect the first circuit breaker. Thus, precise control of multiple circuit breakers in the circuit breaker device is achieved.

[0099] In the above Figure 6 On the basis of the corresponding embodiment, the embodiment of the present application also provides another circuit breaker control method. Figure 7 A flow chart of another circuit breaker control method provided in an embodiment of the present application. The method further includes:

[0100] S104: Acquire a detection signal of at least one downstream circuit breaker of each circuit breaker.

[0101] In a circuit formed by a multi-pole circuit breaker, the circuit breaker may have a corresponding upstream circuit breaker and may also have a corresponding downstream circuit breaker.

[0102] When actually controlling the circuit breaker, in order to improve the control accuracy, the control decision can be made by referring to the actual measured signals of the current circuit breaker and at least one downstream circuit breaker. Therefore, it is necessary to obtain the detection signal of at least one downstream circuit breaker of each circuit breaker.

[0103] If the downstream circuit breaker and the second circuit breaker are controlled by the same control board, the detection signal can be directly obtained. If the downstream circuit breaker and the second circuit breaker are controlled by different control boards, the detection signal of at least one downstream circuit breaker of each circuit breaker is obtained through the control board connected to the downstream circuit breaker.

[0104] S105. Determine whether each circuit breaker meets a preset protection condition according to a detection signal of at least one downstream circuit breaker.

[0105] S106: If the second circuit breaker among the at least two circuit breakers meets the preset protection condition, determine a target downstream circuit breaker from the at least one downstream circuit breaker of the second circuit breaker according to a detection signal of the second circuit breaker and a detection signal of at least one downstream circuit breaker of the second circuit breaker.

[0106] If the second circuit breaker meets the preset protection conditions, the second circuit breaker can be directly opened. Although the second circuit breaker is protected, all downstream circuit breakers will stop working, causing great losses, and manual recovery is required, which is difficult to operate.

[0107] The detection signal of the second circuit breaker is equal to the sum of the detection signals of all downstream circuit breakers. If the second circuit breaker meets the preset protection condition, it may only be necessary to perform the opening operation on some downstream circuit breakers to reduce the sum of the detection signals of the downstream circuit breakers, thereby reducing the detection signal of the second circuit breaker, so that the second circuit breaker does not meet the preset protection condition. Thus, the loss of stopping the operation of some downstream circuit breakers is exchanged for the normal operation of the second circuit breaker and other downstream circuit breakers.

[0108] Among them, when determining the target downstream circuit breaker from at least one downstream circuit breaker of the second circuit breaker, the target downstream circuit breaker can be determined by calculation according to the calculation principle, so that the second circuit breaker does not meet the preset protection condition. The protection sequence of the downstream circuit breakers can also be preset, and the downstream circuit breakers are sequentially determined as the target downstream circuit breakers according to the protection sequence until the second circuit breaker does not meet the preset protection condition.

[0109] For example, take the current signal as an example. If the detection current of the second circuit breaker is 10A, the detection currents of the three downstream circuit breakers of the second circuit breaker are 2A, 3A, and 5A respectively, and the protection current of the second circuit breaker is 9A. Then, only the downstream circuit breakers with detection currents of 2A are determined as the target downstream circuit breakers for control, without affecting the normal operation of the second circuit breaker and other downstream circuit breakers.

[0110] S107: Control the target downstream circuit breaker to perform an opening operation to protect the second circuit breaker.

[0111] If the target downstream circuit breaker and the second circuit breaker are controlled by the same control board, they can be directly controlled. If the target downstream circuit breaker and the second circuit breaker are controlled by different control boards, the control instruction for performing the opening operation is transmitted to the control board connected to the target downstream circuit breaker to control the target downstream circuit breaker to perform the opening operation to protect the second circuit breaker.

[0112] In summary, in this embodiment, the detection signal of at least one downstream circuit breaker of each circuit breaker is obtained; according to the detection signal of at least one downstream circuit breaker, it is determined whether each circuit breaker meets the preset protection condition; if the second circuit breaker among the at least two circuit breakers meets the preset protection condition, the target downstream circuit breaker is determined from at least one downstream circuit breaker of the second circuit breaker according to the detection signal of the second circuit breaker and the detection signal of at least one downstream circuit breaker of the second circuit breaker; the target downstream circuit breaker is controlled to perform the opening operation to protect the second circuit breaker. Thus, the control efficiency and control accuracy of the circuit breaker are improved, and the working efficiency of the circuit breaker device is improved.

[0113] Furthermore, in another embodiment of the present application, the power board is connected to a preset AC power supply, directly draws power from the preset AC power supply, and supplies power to the control board and the communication board, and supplies power to multiple circuit breakers through the control board. Even if some circuit breakers are disconnected, the control board can still use power normally to control other circuit breakers.

[0114] For example, among the multiple circuit breakers, there are a main circuit breaker and a downstream circuit breaker of the main circuit breaker. If the main circuit breaker is opened, no current will flow through the load circuit where the downstream circuit breaker of the main circuit breaker is located. At this time, if the downstream circuit breaker is to be operated, it must be operated on site by a staff member. In this embodiment, since the control panel can always use electricity normally, the downstream circuit breaker can also be controlled separately after the main circuit breaker is opened, avoiding the circuit breaker being unable to be controlled in some cases.

[0115] The following describes a circuit breaker control device, equipment, storage medium, etc. provided by the present application for execution. The specific implementation process and technical effects are described above and will not be repeated below.

[0116] Figure 8 A schematic diagram of a circuit breaker control device provided in an embodiment of the present application is shown in FIG. Figure 8 As shown, any control panel applied to the circuit breaker device in any of the above embodiments, the device comprises:

[0117] The acquisition module 801 is used to acquire detection signals of at least two circuit breakers.

[0118] The judgment module 802 is used to judge whether the detection signals of at least two circuit breakers meet the preset protection conditions.

[0119] The control module 803 is configured to control the first circuit breaker to perform a tripping operation to protect the first circuit breaker if the first circuit breaker among the at least two circuit breakers meets a preset protection condition.

[0120] Furthermore, the acquisition module 801 is further configured to acquire a detection signal of at least one downstream circuit breaker of each circuit breaker.

[0121] Furthermore, the judging module 802 is further configured to judge whether each circuit breaker meets a preset protection condition according to a detection signal of at least one downstream circuit breaker.

[0122] Furthermore, the control module 803 is also used to determine a target downstream circuit breaker from at least one downstream circuit breaker of the second circuit breaker according to a detection signal of the second circuit breaker and a detection signal of at least one downstream circuit breaker of the second circuit breaker if the second circuit breaker among the at least two circuit breakers meets a preset protection condition.

[0123] Furthermore, the control module 803 is also used to control the target downstream circuit breaker to perform a tripping operation to protect the second circuit breaker.

[0126] The storage medium 902 is used to store program data, and the processor 901 calls the program stored in the storage medium 902 to execute the above method embodiment. The specific implementation method and technical effect are similar and will not be repeated here.
