Technical Field

[0002] With the increasing number of household electrical appliances, single-phase circuit fires are occurring frequently, posing a serious threat to life and property safety. Accurately identifying the causes of fires and carrying out targeted prevention are crucial, but this requires extensive simulation experiments and data support.

[0003] Currently, existing electrical fire fault simulation devices often suffer from limited functionality, typically only capable of simulating a single fault type. This makes it difficult to comprehensively reproduce common fire causes in household wiring, such as short circuits and poor connections, as well as the complex interactions between fire and faults. Furthermore, in terms of data acquisition and analysis, the lack of collaborative integration of multi-source information and insufficient recording of the fault process limits the accuracy and reliability of fire cause identification, hindering the ability to meet the needs of in-depth research on electrical fires in practical applications.

Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0020] This utility model discloses a single-phase line arc fault simulation device, which is particularly suitable for simulating single-phase line fires in scenarios such as homes.

[0021] In one embodiment, the single-phase line arc fault simulation device of this application includes: a single-phase voltage regulator 1, a single-phase energy meter 2, a switch 3, a current transformer 4, a voltage transformer 5, a fire simulation generator 6, a metering module 7, and a control and analysis module 8. Connection diagram as shown Figure 1 As shown; The input terminal of the single-phase voltage regulator 1 is used to connect the neutral wire and the live wire in a single-phase power supply, and is used to simulate the two modes of abnormal and normal single-phase power supply voltage. The input terminal of single-phase energy meter 2 is connected to the output terminal of single-phase voltage regulator 1; The input terminal of switch 3 is connected to the output terminal of single-phase energy meter 2, and the voltage transformer 5 and fire simulator 6 are connected in parallel to the output terminal of switch 3. The fire simulator 6 is connected to the switch 3 and is used to simulate the current through the switch 3. The voltage transformer 5 is used to monitor the voltage data during the simulation process. Furthermore, the current transformer 4 is installed on the live wire between the switch 3 and the fire simulator 6; it is used to monitor the current data during the simulation process.

[0022] In this application, the signal output terminals of the single-phase energy meter 2, the current transformer 4, the voltage transformer 5, and the fire simulator 6 are respectively connected to the input terminal of the metering module 7. The output of metering module 7 is connected to the input of control analysis module 8; the output of control analysis module 8 is connected to the control input of fire simulator 6.

[0023] Preferably, a wireless communication module is provided between the metering module 7 and the single-phase energy meter 2 for remotely reading the household electricity consumption data recorded by the single-phase energy meter 2.

[0024] In some alternative embodiments, the fire simulator 6 includes: Short circuit ignition simulation unit 61, poor contact ignition simulation unit 62, fire and poor contact interaction simulation unit 63, camera 64 and household appliances 65; The short-circuit ignition law simulation unit 61, the poor contact ignition law simulation unit 62, and the fire and poor contact interaction relationship simulation unit 63 are connected in parallel to the output terminal of the switch 3, that is, connected to the neutral / live wire of the switch output terminal; the household appliance 65 is connected in series in the circuit formed by the neutral wire and the live wire of each simulation unit to provide load current to the simulation unit.

[0025] In this embodiment, the structural schematic diagram of the fire simulator 6 is as follows: Figure 2 As shown; The camera 64 is mounted above the fire simulator 6 and is used to capture the combustion process during simulated experiments such as short-circuit ignition and poor contact ignition. The signal output terminal of the camera 64 is connected to the metering module 7 or the control and analysis module 8.

[0026] Furthermore, in some embodiments, the short-circuit ignition law simulation unit 61 includes: A first fireproof and heat-insulating insulating platform 611, and a first insulating support 612, a first combustible material 613 and a first nano-level micro-motion platform 614 are arranged horizontally on the first fireproof and heat-insulating insulating platform 611 in sequence; a first insulating clip 615 is installed on the first insulating support 612; the first insulating clip 615 is used to fix the neutral wire led out by the switch 3. The live wire from switch 3 passes through household appliance 65 and is then held by the first nanoscale micro-motion platform 614 under the control of the control and analysis module 8, causing the neutral wire from switch 3 to move. When the live wire contacts the neutral wire, a short-circuit current can be provided to ignite the first combustible material 613. For example, in this application, during a simulated short-circuit ignition experiment, such as... Figure 2 The first nanometer-level micro-motion platform 614 moves to the left, and by creating a short-circuit parallel fault arc under controllable zero-live wire spacing, the law of ignition of combustibles by the zero-live wire spacing and the short-circuit parallel fault arc is studied.

The control terminal of the second nanometer-scale micro-motion platform 624 is connected to the control analysis module 8, and is used to clamp and drive the first segment of the live wire to move towards the live wire led out from the switch 3. The other end of the first segment of the live wire is connected to the household appliance 65, and the other end of the household appliance 65 is connected to the neutral wire output from the switch 3, forming a circuit. This circuit is used to provide current to ignite the second combustible material 623 when the live wire led out from the switch 3 comes into contact with the first segment of the live wire. For example, in simulating a poor contact ignition experiment, the second nanometer-scale micro-motion platform 624 can be moved to the left. By creating a series fault arc under controllable spacing between the two segments of the live wire, the law of the spacing between the two segments of the live wire and the ignition of the combustible material by the series fault arc can be studied.

The control terminal of the third nanometer-level micro-motion platform 634 is connected to the control analysis module 8, and is used to clamp and drive the second section of the live wire to move towards the live wire led out by the switch 3. The other end of the second section of the live wire is connected to the household appliance 65, and the other end of the household appliance 65 is connected to the neutral wire output by the switch 3, forming a circuit, which is used to provide current to make the flame generator 633 burn when the live wire led out by the switch 3 comes into contact with the second section of the live wire.

[0029] For example, in the experiment simulating the interaction between fire and poor contact, the third nanometer-level micro-motion platform 634 moves to the left to create a series fault arc under the condition that the distance between the fire wires is controllable, thereby obtaining the interaction law between the series arc between the fire wires and the flame size.

[0030] In one optional embodiment, the first nanometer-level micro-motion platform 614, the second nanometer-level micro-motion platform 624, and the third nanometer-level micro-motion platform 634 each include a linear motor, a voice coil motor, a piezoelectric ceramic, and an insulating clamp for holding experimental wires, arranged in series in the direction of movement. The three motion mechanisms drive the insulating clamp to move rapidly and precisely to the left and right.

[0031] Furthermore, the control terminals of the linear motor, the voice coil motor, and the piezoelectric ceramic are respectively connected to different control output terminals of the control analysis module 8.

[0032] In this embodiment, as Figure 3 As shown, each nanoscale micro-motion platform has the following structure: The base 601, the linear guide shaft 602 fixed to the base 601, and the linear motor, the voice coil motor and the piezoelectric ceramic driver arranged in series along the linear guide shaft 602. The linear motor includes a first stator 603 fixed to the base 601 and a first mover 604 that can move linearly; the first mover 604 serves as a primary moving platform. The voice coil motor includes a second stator 605 and a linearly movable second mover 606. The second stator 605 is fixedly mounted on the first mover 604, and the second mover 606 is fixedly connected to the voice coil motor output platform 607. The voice coil motor output platform 607 serves as a secondary moving stage. The piezoelectric ceramic driver includes a third stator 609 fixed to the voice coil motor output platform 607 and a linearly telescopic third mover 6010. The third mover 6010 is fixedly connected to the piezoelectric ceramic output platform 6011, which serves as an end output platform. The 6011 piezoelectric ceramic output platform is used to install insulating clamps.

[0033] Furthermore, a first corrugated spring 608 is provided between the voice coil motor output platform 607 and the third stator 609; A second corrugated spring 6012 is provided between the piezoelectric ceramic output platform 6011 and the insulating clamp to ensure that the electric repulsive force generated when the conductor driven by the insulating clamp generates an electric arc does not affect the subsequent vibration.

[0034] During operation, the linear motor receives current control signals from the control and analysis module, generating millimeter-level displacement to the left or backward; The voice coil motor receives the current control signal from the control and analysis module and generates a micron-level displacement to the left or backward. The piezoelectric ceramic receives the voltage control signal from the control and analysis module, generating a nanometer-level displacement to the left or backward.

[0035] In one specific embodiment, the experimental simulation steps in each simulation unit of this application are as follows: 1. Short-circuit ignition simulation: (1) Prepare for the experiment. Use the short-circuit ignition law simulation unit, place the combustible material at a certain distance from the short-circuit test point, and close the switch. (2) Adjust the voltage regulator to 220V output (when simulating the short-circuit parallel fault arc igniting combustibles under abnormal voltage conditions, adjust the voltage regulator to the abnormal voltage value). (3) Close the household appliance to generate current between the live and neutral wires; (4) The control and analysis module issues a control command. After receiving the command, the nano-level micro-motion platform drives the millimeter-level linear motor to move the experimental wire to the left at a rapid millimeter level. When the neutral wire and the live wire are close, the micrometer-level voice coil motor is driven to slowly approach. Then, the nano-level piezoelectric ceramic is driven to vibrate left and right at the nanometer level to finely adjust the distance between the neutral wire and the live wire until a short circuit and parallel fault arc occurs between the neutral and live wires. (5) The metering module records the live wire current, the voltage between the live and neutral wires, and the data in the single-phase energy meter during the process of the short-circuit parallel fault arc igniting the combustible material, and packages the above data and sends it to the control and analysis module. (6) The control and analysis module stores the received data into the short-circuit ignition pattern database until the short-circuit parallel fault arc of the live and neutral wires can no longer ignite the combustibles.

[0036] 2. Simulation of ignition due to poor contact: (1) Prepare for the experiment. Use the poor contact ignition law simulation unit, place the combustible material at a certain distance from the poor contact test point, and close the switch. (2) Adjust the voltage regulator to 220V output; (3) Close the household appliance to generate current in the live wire; (4) The control and analysis module issues a control command. After receiving the command, the nano-level micro-motion platform drives the millimeter-level linear motor to move the experimental wire to the left millimeter level quickly. When the two sections of the live wire are close to each other, the micrometer-level voice coil motor and the nano-level piezoelectric ceramic are driven to slowly approach each other until the two sections of the live wire experimental wire experience a series fault arc due to poor contact. (5) The metering module records the live wire current, the voltage between the live and neutral wires, and the data in the single-phase energy meter during the process of the arc of poor contact series fault igniting the combustible material, and packages the above data and sends it to the control and analysis module. (6) The control and analysis module stores the received data into the poor contact ignition law database until the poor contact series fault arc can no longer ignite the combustible material.

[0037] 3. The simulation steps for the interaction between fire and poor contact are the same as those for the simulation steps for ignition due to poor contact, and will not be repeated here.

[0038] It should be noted that the control and analysis module of this application is an existing, general-purpose hardware component. The improvement of this utility model does not lie in the module itself or its internal analysis method, but in that it provides a standardized control command interface and execution path for the entire novel hardware system. Its technical effect stems from the hardware closed loop of the execution mechanism (nanometer-level micro-motion platform) that receives commands and the sensing system that provides data.
