Example one
Fig. 1 is a schematic flow diagram of a method of an intelligent internet-of-things universal circuit breaker according to an embodiment of the present invention, and the method of the intelligent internet-of-things universal circuit breaker according to the embodiment of the present invention is applied to a circuit breaker, the circuit breaker is in communication connection with a central control terminal, and the circuit breaker refers to a switching device capable of closing, carrying, and opening/closing a current under a normal circuit condition and capable of closing, carrying, and opening/closing a current under an abnormal circuit condition within a specified time. The circuit breaker is classified into a high-voltage circuit breaker and a low-voltage circuit breaker according to the range of use, and the high-voltage and low-voltage boundary line is relatively vague, and generally, a circuit breaker with a voltage of 3kV or more is called a high-voltage apparatus. The circuit breaker can be used for distributing electric energy, starting an asynchronous motor infrequently, protecting a power supply circuit, the motor and the like, and automatically cutting off a circuit when faults such as serious overload, short circuit, undervoltage and the like occur, and the function of the circuit breaker is equivalent to the combination of a fuse type switch, an over-under-heat relay and the like. Furthermore, no parts need to be changed after breaking the fault current. At present, it has been widely used. The circuit breaker in the embodiment of the application can be in communication connection with a central control end through a network, the connection mode comprises an application of an optical fiber network or a 5G network, and the method comprises the following steps:
step 110: obtaining the working state of the circuit breaker;
specifically, the working state of the circuit breaker includes a normal working state and an abnormal working state, wherein the normal working state is a condition that the circuit breaker has no fault, and the abnormal working state is a condition that the circuit breaker has a fault and cannot work normally.
Step 120: judging whether the working state is in a brake-off state or not;
specifically, the normal working state of the circuit breaker comprises an opening state and a closing state, wherein the opening state is that when the real-time current of the protected circuit exceeds the rated current, the protected circuit is disconnected for protecting the circuit, so that the protected circuit is in an open circuit state; and on the premise of controlling the electricity utilization safety of the protected circuit in the closing state, the protected circuit is in a passage state.
Step 130: if the working state is in a switching-off state, acquiring first switching-off time and second switching-off time of the circuit breaker, and recording and storing the first switching-off time and the second switching-off time;
step 140: obtaining a time difference between the first time and the second time;
specifically, the opening time may represent the time for the circuit breaker to open the protected circuit when the current of the protected circuit exceeds the rated current in the normal working state of the circuit breaker, where the first opening time and the second opening time refer to the time of two adjacent opening actions, and the central control end receives the opening time through the network and stores and records the multiple opening times, so as to facilitate subsequent management. And subtracting the two adjacent switching-off times to obtain the time difference of the two switching-off times, namely the time interval between the two protected circuits when the current exceeds the rated current.
Step 150: obtaining a predetermined time threshold;
step 160: judging whether the time difference is smaller than the preset time threshold value or not;
step 170: and if the time difference is smaller than the preset time threshold, obtaining first instruction information, wherein the first instruction information is used for controlling the circuit breaker to stop a closing action.
Specifically, the predetermined time threshold may be set according to an actual situation, and is used to determine whether a time difference between two switching-off operations is too short, and whether a potential safety hazard exists. For example, when a breaker has multiple tripping conditions and the time interval between every two tripping conditions is less than a certain specified time, it can be understood that the breaker has multiple tripping conditions in a short time, and can infer that a protected circuit has a hard fault and needs to be maintained, thereby ensuring the power consumption safety, when the above-mentioned conditions occur, the prior art cannot remotely supervise and control the working state of the breaker, for example, when the above-mentioned fault occurs, a power consumer can perform multiple switching operations on the breaker due to unclear fault reasons, but because the fault of the protected circuit is not eliminated, the breaker still causes tripping after switching on, such that multiple switching on and switching off are performed, and the current exceeds the rated current for multiple times in a short time or is in an excessive current state for a long time, so as to easily cause damage to the protected circuit, in the embodiment of the present application, when the above-mentioned problems occur, when the two-time switching-off time is less than the preset time threshold, the central control end sends first instruction information to the circuit breaker to control the circuit breaker to stop switching-on action, and therefore the technical effect of circuit damage is avoided.
Further, after obtaining the operating state of the circuit breaker, the method includes: obtaining a first predetermined time period; according to the working state and the first preset time period, obtaining the opening times of the circuit breaker in the first preset time period; obtaining a preset brake-separating frequency threshold value; and if the switching-off times in the first preset time period exceed the preset switching-off time threshold, obtaining first early warning information, wherein the first early warning information is used for prompting that the protected circuit breaks down and needs to be maintained as soon as possible.
Specifically, the opening, closing and operation time of the circuit breaker can be obtained through the operating state of the circuit breaker recorded in step 110, the first predetermined time period can be a safety time set according to actual conditions, and can be five minutes, half an hour and the like, so as to obtain the number of times of opening the circuit breaker in the first predetermined time period, for example, when the circuit breaker starts to open once, the predetermined time period is assumed to be 5 minutes, and after five minutes, the circuit breaker has 3 opening operations. The preset switching-off frequency threshold is the maximum frequency of switching-off actions of the circuit breaker under the condition that the power utilization safety of the protected circuit is guaranteed in a first preset time period, for example, the preset switching-off frequency threshold is 2 times, 3 switching-off actions of the circuit breaker occur in the first preset time period, if the preset switching-off frequency threshold is exceeded, the possibility that the protected circuit fails is high, and the circuit needs to be maintained as soon as possible.
Further, after obtaining the operating state of the circuit breaker, the method further includes: if the working state is an opening state, obtaining a first current of the protected circuit, wherein the first current is a real-time current of the protected circuit before the breaker is opened; obtaining the rated current of the protected circuit; judging whether the first current exceeds the rated current or not; and if the first current does not exceed the rated current, second early warning information is obtained and used for prompting the breaker to break down.
Specifically, in order to remotely monitor whether the working state of the circuit breaker is normal or not, the central control end obtains the working current of the protected circuit and the rated current in real time, when the breaker is in opening action, in order to judge whether the breaker is in opening action caused by the protection of the protected circuit or in opening action caused by the fault of the breaker, therefore, when the breaker is opened, the first current of the protected circuit, namely the real-time current of the protected circuit before opening, is verified whether exceeds the rated current or not, if the rated current is exceeded, the circuit breaker is normally operated, if the rated current is not exceeded, the circuit breaker is in failure, therefore, the second early warning information is obtained, the circuit breaker is prompted to break down, the remote monitoring on the circuit breaker is achieved, the working efficiency of the circuit breaker is improved, and the technical effect of reducing the failure rate is achieved.
Further, after obtaining the second warning information if the first current does not exceed the rated current, the method includes: obtaining second instruction information according to the second early warning information; and controlling the circuit breaker to be in a closing state according to the second instruction information.
Specifically, if the breaker is subjected to a brake opening action caused by self operation errors, the central control end sends second instruction information to the breaker according to the second early warning information to control the breaker to be in a closing state, and the normal power supply of the protected circuit is recovered, so that the technical effects of reducing the fault rate of the breaker and improving the normal operation rate of the protected circuit are achieved.
Further, after obtaining the operating state of the circuit breaker, the method further includes: if the working state is a closing state, obtaining a second current of the protected circuit, wherein the second current is a real-time current of the protected circuit; obtaining the rated current of the protected circuit; judging whether the second current exceeds the rated current or not; and if the second current exceeds the rated current, third early warning information is obtained and used for prompting the breaker to break down.
Specifically, in order to remotely monitor whether the working state of the circuit breaker is normal or not, the central control end obtains the working current of the protected circuit and the rated current in real time, when the circuit breaker is in a closing state, in order to judge whether the circuit breaker is normally operated due to protection or not because the circuit breaker breaks down and the circuit breaker is not switched off due to overlarge current of the protected circuit, when the circuit breaker is closed, the first current of the protected circuit, namely the real-time current of the protected circuit is verified whether the rated current is exceeded or not, if the rated current is not exceeded, the circuit breaker is normally operated, if the rated current is exceeded, the circuit breaker is in failure, therefore, the third early warning information is obtained to prompt the circuit breaker to break down, so that the remote monitoring on the circuit breaker is achieved, the working efficiency of the circuit breaker is improved, and the technical effect of reducing the failure rate is achieved.
Further, after obtaining third warning information if the second current exceeds the rated current, the method includes: obtaining third instruction information according to the third early warning information; and controlling the circuit breaker to be in an opening state according to the third instruction information.
Specifically, if the breaker is not subjected to switching-off action due to self operation error, the central control end sends third instruction information to the breaker according to the third early warning information to control the breaker to perform switching-off action, stop normal power supply of a protected circuit and disconnect the protected circuit, so that the technical effects of reducing the fault rate of the breaker and improving the normal operation rate of the protected circuit are achieved.
Preferably, the circuit breaker has a smoke sensor, the method comprising: obtaining real-time smoke content information in the air around the circuit breaker according to the smoke sensor; obtaining a predetermined smoke content threshold; judging whether the real-time smoke content information exceeds the preset smoke content threshold value; if the real-time smoke content information exceeds the preset smoke content threshold value, fourth instruction information is obtained; and controlling the breaker to be in an opening state according to the fourth instruction information.
Particularly, circuit system often can take place circuit failure and lead to dangerous accident if meet open fire, in order to avoid the occurence of failure, this application embodiment increases smoke transducer for the circuit breaker, can respond to the smog content around the circuit breaker in real time, when smog content exceeds predetermined smog content threshold value around, there may be the conflagration danger in the surrounding environment, in order to avoid the circuit to cause the occurence of failure because of contacting open fire, send fourth instruction information to the circuit breaker, control circuit breaker carries out the action of separating brake, stop by the normal power supply of protection circuit, the disconnection by the protection circuit, reach and reduce the circuit breaker fault rate, improve the technological effect by the normal operating rate of protection circuit. Further, if the real-time smoke content information exceeds the preset smoke content threshold value, first position information of the circuit breaker is obtained; and obtaining third early warning information according to the first position information, wherein the third early warning information is used for informing the circuit manager that the smoke at the first position is too large.
