[0056] In the above Figure 1 On the basis of the corresponding embodiment, the application also provides a circuit breaker. Figure 2A structural schematic diagram of a circuit breaker is provided in the embodiment of the present application. As shown in Figure 2 each circuit breaker comprises a switch mechanism 11, an execution unit 12, a sensor 13 and a relay board 14.

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

[0059] By way of example, the sensor 13 can be a current transformer (or a 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 setting the relay board 14, the internal wiring of the circuit breaker 1 is made more clear, the wiring resources are saved, and the later maintenance is facilitated.

Thus, the wiring resources are saved, and the later maintenance is facilitated.

[0062] In the above Figure 2 On the basis of the corresponding embodiment, the embodiment of the present application further provides another circuit breaker. Figure 3 A structural schematic diagram of another circuit breaker is provided in the embodiment of the present application. As shown in Figure 3 each circuit breaker further comprises a storage unit 15, the storage unit 15 is arranged on the relay board 14, and the storage unit 15 is connected to the control board 2.

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

[0064] When the circuit breaker 1 is added, the control board 2 can timely acquire information parameters of the circuit breaker 1 through the storage unit 15. And the information parameters can be transmitted to a terminal device through the communication board 4 to be displayed to a user.

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

[0066] In the above Figure 2 Based on the corresponding embodiment, the embodiment of the present application further provides another circuit breaker. Figure 4 A structural schematic diagram of another circuit breaker provided by the embodiment of the present application is shown.

[0067] As Figure 4 shown, the circuit breaker device further comprises an indication unit 16, which is connected to the control board 2 through the adapter board 14.

[0068] When the control execution unit 12 controls the switching mechanism 11 to close / open, the indication unit 16 can be controlled to indicate at the same time, and the state of the switching mechanism 11 can be obtained through the indication signal of the indication unit 16.

[0069] For example, the indication unit 16 can be an LED lamp. When the switching mechanism 11 is closed, the LED lamp is off, and when the switching mechanism 11 is opened, the LED lamp is always on / flashing.

[0070] In summary, in the embodiment, the circuit breaker device further comprises an indication unit, which is connected to the control board through the adapter board. Thus, the state of the circuit breaker can be accurately indicated.

[0071] In the above Figure 1 Based on the corresponding embodiment, the embodiment of the present application further provides a control board. Figure 5 A structural schematic diagram of a control board provided by the embodiment of the present application is shown.

[0072] As Figure 5 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 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 is connected to the communication board 4.

[0074] The sampling unit 23 obtains the sensing signal transmitted by the sensor 13 through the adapter board 14 and transmits the sensing signal to the processing unit 22. The processing unit 22 processes according to the sensing signal and the protection parameters of the circuit breaker 1 to obtain a processing result, and transmits a control instruction corresponding to the processing result to the control unit 21. The control unit 21 transmits a 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 switching mechanism 11.

[0075] The control board 2 is internally designed in a modular manner, and the control unit 21, the processing unit 22 and the sampling unit 23 are detachably connected, facilitating later maintenance.

[0076] In summary, in the 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, the control unit is connected to at least two circuit breakers, and the control unit is connected to the communication board. Thus, the control board resources are saved, and later maintenance is facilitated.

[0077] On the basis of the above embodiment, the plurality of circuit breakers 1 in the embodiment of the application are arranged in the first area of the preset shell, and the at least one control board 2, the power board 3 and the communication board 4 are arranged in the second area of the preset shell which is away from the first area.

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

[0079] The control board 2, the power board 3 and the communication board 4 are arranged in the same area, and the plurality of circuit breakers 1 are arranged in another area. The plurality of circuit breakers 1 can share the control board 2, the power board 3 and the communication board 4 in the second area, and the resource utilization rate is high. The layered layout rationally utilizes the different area spaces of the preset shell space, without occupying additional space, thereby improving the space utilization rate.

[0080] In summary, in the embodiment, the plurality of circuit breakers are arranged in the first area of the preset shell, and the at least one control board, the power board and the communication board are arranged in the second area of the preset shell which is away from the first area. Thus, the different area spaces of the preset shell space are rationally utilized, without occupying additional space, thereby improving the space utilization rate.

[0081] On the basis of the above embodiment, the plurality of circuit breakers 1 in the embodiment of the application are arranged in the first area; and the at least one control board 2, the power board 3 and the communication board 4 are integrally arranged in the base in the second area.

[0082] The at least one control board 2, the power board 3 and the communication board 4 are integrally arranged in the base in the second area, forming an intelligent base. The plurality of circuit breakers 1 are detachably connected to the base, facilitating adjustment of the number of circuit breakers in the circuit breaker device, and improving the working efficiency of the circuit breaker device.

[0083] The strong electricity connection module realizes the connection between the strong electricity indoor and outdoor, and the electric energy transmitted to the control board 2 and the communication board 4 through the power board 3 is weak electricity. There are no strong electricity components or only a small amount of analog components in the circuit breaker 1. When performing EMC test, the required protection components are concentrated in the base, reducing resource waste, saving cost and space.

[0084] In summary, in the embodiment, a plurality of circuit breakers are arranged in the strong electricity connection module in the first area; at least one control board, a power board and a communication board are integrated in the base in the second area. Thus, the number of circuit breakers in the circuit breaker device can be adjusted, and the working efficiency of the circuit breaker device is improved.

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

[0086] When the plurality of circuit breakers 1 are detachably connected to the base in the second area, plug-in connection can be used for connection.

[0087] By pre-setting the line layout in the circuit breaker device, when the circuit breaker 1 is plugged into the base in the second area, the connection relationship between the circuit breaker 1, the control board 2 and the power board 3 can be realized.

[0088] In summary, in the embodiment, a plurality of circuit breakers are plug-in connected to the base in the second area. Thus, the working efficiency of the circuit breaker device is improved.

[0089] The circuit breaker control method provided by the embodiment of the present application is explained and described as follows by a specific example. Figure 6 A flowchart of a circuit breaker control method provided by the embodiment of the present application. The method is applied to any control board in the circuit breaker device in any of the above embodiments. As shown in the figure, the method comprises: Figure 6

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

[0091] The detection signals of the at least two circuit breakers are obtained through the sensor and the adapter plate.

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

[0093] S102, determining whether the detection signals of the at least two circuit breakers satisfy a preset protection condition.

[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 of current overcurrent, and the preset protection condition is that the measured current value of the circuit breaker exceeds the current threshold of current overflow.

[0096] S103, if the first circuit breaker of the at least two circuit breakers meets the preset protection condition, controlling the first circuit breaker to perform a tripping operation to protect the first circuit breaker.

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

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

[0099] In the above Figure 6 Based on the corresponding embodiment, the embodiment of the present application further provides another circuit breaker control method. Figure 7 The flowchart of another circuit breaker control method provided by the embodiment of the present application is shown in FIG. 4. The method further includes the following steps.

[0100] S104, obtaining the detection signal of at least one downstream circuit breaker of each circuit breaker.

[0101] In the circuit composed of multi-pole circuit breakers, the circuit breaker may have a corresponding upstream circuit breaker, or may have a corresponding downstream circuit breaker.

[0102] When actually controlling the circuit breaker, in order to improve the control accuracy, the measured signals of the current circuit breaker and at least one downstream circuit breaker can be referred to for control decision. Therefore, the detection signal of at least one downstream circuit breaker of each circuit breaker needs to be obtained.

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

[0104] S105, judging whether each circuit breaker meets the preset protection condition according to the detection signal of the 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, determining a target downstream circuit breaker from the 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 the at least one downstream circuit breaker of the second circuit breaker.

[0106] If the second circuit breaker meets the preset protection condition, the second circuit breaker can be directly controlled to perform the tripping operation. Although the second circuit breaker is protected, all downstream circuit breakers stop working, resulting in a large loss and requiring manual recovery, 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, and the second circuit breaker meets the preset protection condition. Only a part of the downstream circuit breakers need to be controlled to perform the tripping operation, so that the sum of the detection signals of the downstream circuit breakers decreases, the detection signal of the second circuit breaker decreases, and the second circuit breaker does not meet the preset protection condition. Thus, the loss of the part of the downstream circuit breakers stopping working is exchanged for the normal working of the second circuit breaker and other downstream circuit breakers.

[0108] In the determination of the target downstream circuit breaker from the at least one downstream circuit breaker of the second circuit breaker, the target downstream circuit breaker can be determined 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 breaker can also be preset, and the downstream circuit breaker is sequentially determined as the target downstream circuit breaker according to the protection sequence until the second circuit breaker does not meet the preset protection condition.

[0109] For example, taking 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, and the protection current of the second circuit breaker is 9A. Only the downstream circuit breaker with a detection current of 2A needs to be determined as the target downstream circuit breaker for control, without affecting the normal working of the second circuit breaker and other downstream circuit breakers.

[0110] S107, controlling the target downstream circuit breaker to perform the tripping 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 panel, they can be directly controlled. If the target downstream circuit breaker and the second circuit breaker are controlled by different control panels, a control instruction for performing the tripping operation is transmitted to the control panel connected to the target downstream circuit breaker to control the target downstream circuit breaker to perform the tripping 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 acquired; based on the detection signal of at least one downstream circuit breaker, it is determined whether each circuit breaker meets the preset protection conditions; if the second circuit breaker among at least two circuit breakers meets the preset protection conditions, then based on the detection signal of the second circuit breaker and the detection signal of at least one downstream circuit breaker of the second circuit breaker, a target downstream circuit breaker is determined from the at least one downstream circuit breaker of the second circuit breaker; the target downstream circuit breaker is controlled to perform a tripping operation to protect the second circuit breaker. This improves the control efficiency and accuracy of the circuit breaker, and enhances the working efficiency of the circuit breaker device.

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

[0114] For example, in a circuit breaker configuration, there is a main circuit breaker and a downstream circuit breaker. If the main circuit breaker trips, no current flows through the load circuit containing the downstream circuit breaker. In this case, any operation on the downstream circuit breaker must be performed by on-site personnel. However, in this embodiment, since the control board is always powered, the downstream circuit breaker can be controlled independently even after the main circuit breaker trips, thus avoiding the situation where the circuit breaker cannot be controlled in certain circumstances.

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

[0122] Further, the control module 803 is further configured to, if the second circuit breaker of the at least two circuit breakers meets the preset protection condition, determine a target downstream circuit breaker 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 the at least one downstream circuit breaker of the second circuit breaker.

[0123] Further, the control module 803 is further configured to control the target downstream circuit breaker to perform the tripping operation to protect the second circuit breaker.
