Detailed Description
To explain technical contents, structural features, and objects and effects of the technical solutions in detail, the following detailed description is given with reference to the accompanying drawings in conjunction with the embodiments.
Referring to fig. 1 to 8, the present embodiment provides a remote networked intelligent circuit breaker, which is applied to a processing chip of the circuit breaker, where the processing chip may be a chip with a processing function, such as a single chip microcomputer. The structure of the circuit breaker can be as shown in fig. 2, the circuit breaker comprises a circuit breaker shell 1, a circuit board 2, a circuit breaking module 3 and a mains supply wiring terminal 4 are arranged in the circuit breaker shell, and a processing chip can be arranged on the circuit board, so that an intelligent circuit breaker is formed. The commercial power terminal generally comprises an upper terminal 40, a live wire terminal 41, a zero line terminal 42 and a zero line terminal 43, wherein the upper terminal (the live wire terminal 40 and the zero line terminal 42) generally serves as external commercial power input, and the lower terminal (the live wire terminal 41 and the zero line terminal 43) generally serves as power supply for places such as families. The circuit breaking module 3 is used for realizing the on-off of the commercial power wiring terminal 4, when the circuit breaking module is closed, the two wiring terminals above and the two wiring terminals below can be respectively conducted, and under the abnormal condition, the circuit breaking module 3 can realize the disconnection of the wiring terminals. The circuit breaking module can realize one or more functions of overload, circuit breaking, electric leakage and the like. The basic principle of the disconnection module is the prior art and is not described in detail here. When the short circuit is broken, the breaking module is generally realized by a bimetallic trip assembly and an overcurrent release 30, and a push rod 31 is arranged in the overcurrent release. When the instantaneous current is overlarge, a coil of the overcurrent release can generate a magnetic field to push the push rod to push upwards, so that the bimetal release assembly is released, and then a circuit is disconnected. In order to realize the detection of the short-circuit state, the invention firstly arranges a tact switch 32 below the push rod, and the tact switch is connected with the processing chip. In order to achieve the depression of the tact switch, the force required for the depression of the tact switch should be smaller than the gravity of the push lever.
During detection, as shown in fig. 1, the method of the invention comprises the following steps: step S101, acquiring a light touch switch state arranged below a push rod of an overcurrent release; step S102 is to send a short-circuit signal to the remote end through the communication module when the light touch switch is pressed to be released. Under normal conditions, the tact switch is pressed by the push rod, and according to the difference of the tact switch, such as a normally open switch or a normally closed switch, the tact switch is correspondingly closed and opened when pressed. When short circuit occurs, the pushing rod pushes upwards, and the state of the tact switch enters the opposite state, namely the state is pressed to enter the normal state of loosening. Through the change state that detects the tact switch, can judge that the circuit breaker is in the short circuit state, and then the state can be sent to the remote end, and user or maintainer can know after the circuit breaker takes place to break off because the disconnection that the short circuit produced like this, avoid need to investigate whether it is circumstances such as electric leakage, overload or short circuit, have improved efficiency.
In order to avoid misjudgment when the circuit breaker is not powered on, the steps may further include: step S301 obtains the light touch switch state arranged below the push rod of the overcurrent release, step S302 detects whether the breaker is closed through the electrifying detection module, and step S103 sends a short circuit signal to the remote end through the communication module when the light touch switch state is pressed to be released in the closed state. The power-on detection module may be a circuit module as shown in fig. 4, and this circuit module may also be disposed on a circuit board. Through opto-coupler and two leading-out terminal interconnect, when the circuit breaker closed, two leading-out terminals can with commercial power connection, then interface J19 can with commercial power connection, the opto-coupler is lighted, KK _ STATE becomes the high level. After closing, if the tact switch is released from pressing, a short-circuit condition is indicated, and then a short-circuit signal is sent. Otherwise, the short-circuit signal is not sent when the state of the tact switch is not changed or the breaker is not closed, so that the signal is prevented from being sent by mistake.
In order to realize multiple functions of the circuit breaker, the embodiment further comprises the following steps: in step S304, leakage current data is acquired by the leakage current module, filtered by an RC (resistance-voltage) filter, and sent to the processing chip, and subjected to AD (analog-to-digital) conversion in the processing chip, and then the leakage current data is sent to the remote end by the communication module. The leakage current module may be a circuit module as shown in fig. 5, and the circuit module may be disposed on a circuit board. The ZCTs 3 and 4 are respectively connected with the secondary side of the leakage current transformer, then the voltages of the I2P and the I2N are sampled, and then the voltages are converted into current data, so that leakage current data can be respectively collected. Therefore, the processing chip can know the leakage current condition and send the leakage current condition to the remote end through the communication module, and a remote user or maintenance personnel can know the leakage current condition.
In some embodiments, in order to implement automatic power off when the leakage current is too large, the method further includes step S305 of detecting whether leakage current data is greater than a leakage current preset value, and if the leakage current data is greater than the leakage current preset value, driving a push rod of a trip coil to generate upward thrust, so that the bimetallic trip assembly trips, and the circuit breaking module implements opening, and generally needs to send a leakage current alarm signal to a remote end to remind a user or a maintenance person of sending a leakage current trip condition. In some embodiments, the remote end may send the leakage current preset value to the processing chip, and then may change the preset value, and in contrast to the existing leakage protector with a fixed preset value, this embodiment may implement adaptation to different situations in different scenarios.
The circuit breaker still generally has the electric leakage and tries jumping the function, presses down and tries jumping the button after, and the circuit breaker can be because of the electric leakage tripping operation, can detect like this that the electric leakage function is normal. The method comprises the steps of obtaining a trial jump state through a trial jump detection switch arranged behind a trial jump button, if the trial jump state is achieved and leakage current data are larger than a leakage current preset value, not sending a leakage current alarm signal to a remote end through a communication module, and otherwise, if the leakage current data are larger than the leakage current preset value and not in the trial jump state, sending the leakage current alarm signal to the remote end through the communication module. The trial jump detection switch can be directly arranged behind the trial jump button, so that when the trial jump button is pressed down, the trial jump detection switch can be switched on and detected by the processing chip, the current trial jump state can be known, and the phenomenon that a leakage current alarm signal is sent by mistake to cause user trouble is avoided.
In order to implement overload detection, this embodiment further includes, on the basis of any of the above embodiments, the steps of: whether the circuit current signal is larger than the circuit current preset value or not is detected through the current detection module, if the circuit current signal is larger than the circuit current preset value, the push rod of the tripping coil is driven to generate upward thrust, the bimetallic tripping assembly is tripped, and the circuit breaking module realizes brake separation. As shown in FIG. 6, the current detection modules I-1 and I +1 are respectively connected to the secondary side of the current transformer, and the sampled voltages I1P and I1N are sent to the processing chip for processing.
In order to realize the detection of the reverse docking, the method further comprises the following steps: temperature signals are obtained through a temperature sensor arranged near a zero line incoming line terminal, the temperature signals are sent to a remote end through a communication module, and a reverse connection alarm signal is sent to the remote end after the temperature signals are larger than a preset temperature value. Generally, a circuit breaker is identified on the surface of the circuit breaker to distinguish between a neutral line and a live line. As shown in fig. 7, with a neutral flag 5 on the circuit breaker, a temperature sensor 6 may be provided near the neutral inlet terminal. When the circuit is reversely connected, the temperature at the zero line can rise, so that the detection of reverse connection can be realized, and the safety of the circuit is ensured.

The remote end can be a remote server, a remote palm device such as a mobile phone and the like.
In order to realize the centralized forwarding of information and avoid that each breaker needs an independent networking module to send to a remote end, as shown in fig. 8, the remote end is a concentrator connected with a collector through power carrier, and the collector sends to the concentrator through power carrier after receiving the information of a processing chip through a bluetooth module. The collector can be a device with a processing chip, can receive, process and forward information, and can store data reported by the circuit breaker first and then send the data to the concentrator in a unified way after a period of time.
