As shown in fig. 6, the automatic circuit breaker detection system includes a circuit breaker and detection apparatus 200 provided in any of the embodiments of the present application. Wherein the detecting device 200 is connected with the breaker body 100. Specifically, the detecting device 200 includes a control terminal 210, a state detecting means 220, and a current source generating means 230, the control terminal 210 is connected to the state detecting means 220 and the current source generating means 230, and the control module 120 on the circuit breaker body 100 is connected to the control terminal 210 through the communication module 110. Wherein:

the state detecting device 220 is connected to the circuit breaker body 100, and the state detecting device 220 is configured to detect the on-off state of the circuit breaker and transmit the detected on-off state of the circuit breaker to the control terminal 210.

The current source generating device 230 is connected to the breaker body 100, and the current source generating device 230 is configured to generate a test current required for each protection function test of the breaker and transmit the generated test current to the breaker body 100.

The control terminal 210 is configured to acquire the protection function to be tested of the circuit breaker to generate a corresponding parameter adjustment instruction and a test current generation instruction, and send the parameter adjustment instruction to the control module 120 and the test current generation instruction to the current source generating device 230.

The control module 120 is configured to receive a parameter adjustment instruction sent by the control terminal 210, so as to control the protection parameter adjustment module 130 to adjust the protection parameter according to the parameter adjustment instruction.

In the embodiment of the present application, the control terminal 210 may be a host computer or a Programmable Logic Controller (PLC). Next, an example will be described in which the control terminal 210 is an upper computer. The breaker body 100 may establish a communication connection with an upper computer through the communication module 110, so that the breaker body 100 may receive an instruction transmitted by the upper computer. Specifically, the upper computer may determine the numerical value of each protection parameter corresponding to the protection function to be tested based on the protection function to be tested of the circuit breaker, and further generate a corresponding parameter adjustment instruction and send the parameter adjustment instruction to the circuit breaker body 100. After receiving the parameter adjustment command, the control module 120 on the circuit breaker body 100 can control the protection parameter adjustment module 130 to adjust each protection parameter of the circuit breaker accordingly. Meanwhile, the upper computer can determine corresponding test current based on the protection function to be tested of the circuit breaker, so as to generate corresponding test current generation instruction and send the instruction to the current source generation device 230. The current source generating device 230 generates a corresponding test current after receiving the test current generating command and transmits the test current to the breaker body 100 to test the protection function of the breaker to be tested. After the current source generating device 230 transmits the test current to the breaker body 100, the state detecting device 220 may detect the on-off state of the breaker and transmit the detected on-off state of the breaker to the upper computer. Therefore, the upper computer can judge whether the protection function to be tested of the circuit breaker is qualified or not according to the received on-off state of the circuit breaker. Therefore, the detection of each protection function of the circuit breaker can be automatically completed, and the parameter adjustment instruction is issued to the circuit breaker through the upper computer in the detection process, so that the circuit breaker can automatically adjust the corresponding protection parameters based on the parameter adjustment instruction sent by the upper computer, the protection parameters are not required to be set by manually rotating the knob, the automatic test of each protection function of the circuit breaker can be completed, and the test efficiency and the test accuracy can be improved.

In one embodiment of the application, the control terminal is configured to receive the on-off state of the circuit breaker sent by the state detection device, so as to judge whether the protection function to be detected corresponding to the circuit breaker is qualified or not according to the on-off state.

In this embodiment of the present application, during the testing process, the upper computer (i.e. the control terminal 210) may determine whether the protection function to be tested corresponding to the circuit breaker is qualified according to the received on-off state of the circuit breaker sent by the state detection device 220. Specifically, if the protection function to be tested of the circuit breaker is to be disconnected under each set protection parameter by the protection action to be executed when the current is tested, and at this time, if the on-off state of the circuit breaker received by the upper computer is the disconnected state, the protection function to be tested of the circuit breaker can be determined to be qualified. Conversely, if the on-off state of the circuit breaker received by the upper computer is in a conducting state, the to-be-tested protection function of the circuit breaker can be determined to be unqualified. Similarly, if the protection function to be tested of the circuit breaker is conducted by the protection action to be executed when the current is tested under the set protection parameters, and at the moment, if the on-off state of the circuit breaker received by the upper computer is the conducting state, the protection function to be tested of the circuit breaker can be determined to be qualified. Conversely, if the on-off state of the circuit breaker received by the upper computer is an off state, the to-be-tested protection function of the circuit breaker can be determined to be unqualified.

In one embodiment of the application, the control terminal is configured to obtain a test qualified signal that all protection functions to be tested of the circuit breaker are tested qualified, to generate a fault record clearing instruction based on the test qualified signal, and to send the fault clearing instruction to a control module of the circuit breaker;

correspondingly, the control module is configured to receive a fault record clearing instruction to control the fault record clearing module to clear the fault record generated in the test process according to the fault record clearing instruction.

In this embodiment of the application, after the current protection function to be tested of the circuit breaker is tested to be qualified, the next protection function to be tested of the circuit breaker can be detected until all the protection functions to be tested of the circuit breaker are tested to be qualified. At this time, it is considered that many fault records are generated during the test, and the fault records may cause interference to the user when the circuit breaker is used later. The fault record generated in the process of using the breaker by the user at a later stage is mixed with the fault record generated in the process of testing, so that interference can be brought to the user. Therefore, after acquiring the test qualification signals that all the protection functions to be tested of the circuit breaker are qualified, the upper computer (i.e. the control terminal 210) generates a fault record clearing instruction and sends the fault record clearing instruction to the circuit breaker. Therefore, after receiving the fault record clearing instruction, the control module 120 of the circuit breaker controls the fault record clearing module 140 to clear the fault record generated in the testing process, so that the fault record generated in the testing process can be prevented from causing information interference to the user.

In one embodiment of the application, the control terminal is configured to obtain a test qualified signal that all protection functions to be detected of the circuit breaker are tested qualified, to generate a recovery protection parameter instruction based on the test qualified signal, and to send the recovery protection parameter instruction to a control module of the circuit breaker;

correspondingly, the control module is configured to receive the instruction of recovering the protection parameter, so as to control the original parameter recovering module to recover the original protection parameter according to the instruction of recovering the protection parameter.

In this embodiment of the present application, after all protection functions to be tested of the circuit breaker are tested to be qualified, or after the upper computer sends a fault record clearing instruction to the circuit breaker, the upper computer also generates a protection parameter recovery instruction and sends the protection parameter recovery instruction to the circuit breaker. Thus, after receiving the instruction for recovering the protection parameters, the control module 120 of the circuit breaker controls the original parameter recovering module 150 to recover the original protection parameters, so that the circuit breaker after passing the test can be ensured to be in a normal working state.

In step S730, the on-off state of the circuit breaker after the test current is passed is detected.

Step S740, judging whether the current protection function to be tested of the circuit breaker is qualified or not according to the on-off state.

In the embodiment of the application, the upper computer (i.e. the control terminal) determines the numerical value of each protection parameter corresponding to the current protection function to be tested based on the current protection function to be tested of the circuit breaker, so as to generate a corresponding parameter adjustment instruction and send the corresponding parameter adjustment instruction to the circuit breaker. For example, the upper computer determines the values of parameters such as overload protection current, overload protection time, short-circuit short-time delay current Isd, short-circuit short-time delay time, short-circuit instantaneous current, grounding protection current and the like which need to be set according to the current protection function to be detected of the circuit breaker, and sends the values to the circuit breaker, and the circuit breaker reads the values of the parameters and updates the values of the protection parameters. Meanwhile, the upper computer can determine the test current corresponding to the current protection function to be tested based on the current protection function to be tested of the circuit breaker, so that a corresponding test current generation instruction is generated. The current source generating device generates corresponding test current after receiving the test current generating instruction and transmits the test current to the circuit breaker. Then, the state checking device can be used for detecting the on-off state of the circuit breaker after the test current is passed under the set protection parameters, so as to judge whether the current protection function to be tested of the circuit breaker is qualified or not according to the on-off state of the circuit breaker after the test current is passed under the set protection parameters. Specifically, if the protection function to be tested of the circuit breaker is to be disconnected under each set protection parameter by the protection action to be executed when the current is tested, and at this time, if the on-off state of the circuit breaker received by the upper computer is the disconnected state, the protection function to be tested of the circuit breaker can be determined to be qualified. Conversely, if the on-off state of the circuit breaker received by the upper computer is in a conducting state, the to-be-tested protection function of the circuit breaker can be determined to be unqualified. Similarly, if the protection function to be tested of the circuit breaker is conducted by the protection action to be executed when the current is tested under the set protection parameters, and at the moment, if the on-off state of the circuit breaker received by the upper computer is the conducting state, the protection function to be tested of the circuit breaker can be determined to be qualified. Conversely, if the on-off state of the circuit breaker received by the upper computer is an off state, the to-be-tested protection function of the circuit breaker can be determined to be unqualified. Therefore, the automatic detection of the current protection function to be detected of the circuit breaker can be completed. In this way, all protection functions to be tested of the circuit breaker can be automatically detected.

In the embodiment of the application, the upper computer generates the corresponding parameter adjustment instruction based on the current protection function to be tested of the circuit breaker and transmits the parameter adjustment instruction to the circuit breaker, so that the circuit breaker can correspondingly adjust each protection parameter according to the parameter adjustment instruction transmitted by the upper computer, the protection parameter is not required to be set by manually rotating the knob, automatic test of each protection function of the circuit breaker can be completed, and the test efficiency and the test accuracy can be improved.
