Referring to fig. 1, a first embodiment of the present utility model is described in detail below with reference to fig. 1.
When the circuit adopts a single live wire to supply power, the circuit system is provided with a live wire, a zero wire and a ground wire, and the circuit system adopts the scheme of the first embodiment to detect whether the PE wire is well connected. In a first embodiment, the present utility model provides a wiring structure 10 with a detection circuit, the wiring structure 10 with a detection circuit being provided with a live wire L, a neutral wire N, a ground wire 14. The wiring structure comprises a first detection module 11, a second detection module 12 and a measurement module 13. The first detection module 11 includes a first setting bit for setting the resistance. The second detection module 12 includes a second setting bit for setting the resistance. The ground wire 14 is provided with a device end PE1 and a ground end PE2, and the first detection module 11 is connected between the live wire L and the device end PE 1. The second detection module 12 is connected between the zero line N and the equipment terminal PE1, and the measurement module 13 is configured to detect a voltage of the equipment terminal PE 1. When the first setting bit is provided with a first resistor and the second setting bit is provided with a second resistor, the voltage of the equipment terminal PE1 is the first voltage. Wherein the impedance of the first resistor is different from the impedance of the second resistor. When the first setting bit is provided with the second resistor and the second setting bit is provided with the first resistor, the voltage of the equipment terminal PE1 is the second voltage. Based on the difference between the first voltage and the second voltage, the measurement module 13 determines whether the device terminal PE1 and the ground terminal PE2 are connected on or disconnected. The measuring module 13 comprises a voltmeter for measuring the first voltage and the second voltage and a detection chip for determining whether the PE line is well connected based on the first voltage and the second voltage. Wherein the PE line is the ground line connecting the device to the ground.
Therefore, a user can timely judge whether the ground wire of the equipment is well connected. Therefore, when the ground wire is poor in wiring, a user can repair in time so as to remove faults. The technical problem that a user is difficult to check the broken circuit fault between the PE line and the grounding point of the existing equipment is effectively solved. The user can effectively avoid leakage accidents by using the wiring structure detection circuit with the detection circuit. Thus, the user is safer to use the electrical devices in the industry.
In this embodiment, the user may set the resistor at the first setting bit of the first detection module 11, and the user may set the resistor at the second setting bit of the second detection module 12. In the case of good connection of the PE line, since the ground terminal PE2 and the device terminal PE1 are at the same potential, the voltage between the live line L and the ground terminal PE2 is equal to the voltage between the live line L and the device terminal PE 1. Since the voltage between the live wire L and the ground terminal PE2 does not change, even if resistances with different impedances are provided between the live wire L and the equipment terminal PE1, the voltage between the live wire L and the equipment terminal PE1 does not change, i.e., the first voltage is equal to the second voltage. When the PE connection is bad, the grounding end PE2 is disconnected from the PE line of the device. At this time, the ground terminal PE2 and the device terminal PE1 are not at the same potential, and current flows from the live line L to the neutral line N through the resistor. Meanwhile, the resistor on the first setting bit and the resistor on the second setting bit can divide the voltage between the live wire L and the zero wire N. At this time, the voltage between the live line L and the equipment terminal PE1 is related to the resistance of the resistor on the first set bit, if the resistors with different resistances are set between the live line L and the equipment terminal PE1, and the resistance of the resistor between the zero line N and the equipment terminal PE1 is kept unchanged, the voltage between the live line L and the equipment terminal PE1 will change, and then the first voltage is not equal to the second voltage. Therefore, if the measurement module 13 detects that the difference between the first voltage and the second voltage is equal to 0, the measurement module 13 determines that the device PE1 and the ground PE2 are connected and turned on. If the measurement module 13 detects that the difference between the first voltage and the second voltage is not 0, the measurement module 13 may determine that the device end PE1 and the ground end PE2 are disconnected (i.e. the ground of the related device is broken).
As shown in fig. 1, the first setting bit is provided with a plurality of resistors, and the plurality of resistors on the first setting bit are connected in series. And, the user may change a different resistance at the first set point. The second setting bit is provided with a plurality of resistors, and the plurality of resistors on the second setting bit are connected in series. The user can also change a different resistor at the second setting bit. For example, the user replaces the resistor with a different resistance value at the first set bit, and the resistance of the resistor at the second set bit remains unchanged. Thus, based on the change in the device side voltage, the measurement module 13 may determine whether the device side PE1 and the ground side PE2 are connected on or disconnected. For example, the resistance of the resistor on the first set bit remains unchanged, and the user replaces the resistor of a different resistance value at the second set bit. Thus, based on the change in the device side voltage, the measurement module 13 may determine whether the device side PE1 and the ground side PE2 are connected on or disconnected.
As shown in fig. 1, when the device end PE1 and the ground end PE2 are disconnected, the resistor on the first setting bit and the second settingThe resistor on the bit can divide the voltage between the live wire and the zero wire. The voltage divided by the resistance of the first set bit and the resistance of the second set bit is positively correlated with the resistance of the resistance. The voltage between the neutral line N and the equipment terminal PE1 is determined by the impedance of the resistor on the first set bit, the impedance of the resistor on the second set bit, and the voltage between the live line L and the neutral line N. The calculation formula of the voltage between the zero line N and the equipment end PE1 is as follows:
z1 is the impedance of the resistor on the first set bit, Z2 is the impedance of the resistor on the second set bit, U1 is the voltage between the live wire L and the zero wire N, and U2 is the voltage between the zero wire N and the equipment end PE 1. Of course, the setting bit can set resistance, capacitance, inductance and the combination of the impedance devices according to the needs of users.
Therefore, if the impedance of the resistor on the first set bit is greater than the impedance of the resistor on the second set bit, the voltage between the live wire and the equipment terminal is greater than the voltage between the equipment terminal PE1 and the neutral wire N. And, the voltage between the live wire L and the equipment terminal PE1 is greater than one half of the voltage between the live wire L and the neutral wire N. If the impedance of the resistor on the first set bit is smaller than the impedance of the resistor on the second set bit, the voltage between the live wire L and the equipment terminal PE1 is smaller than the voltage between the equipment terminal PE1 and the neutral wire N. And, the voltage between the live wire L and the equipment terminal PE1 is less than one half of the voltage between the live wire L and the neutral wire N. If the impedance of the resistor on the first set bit is equal to the impedance of the resistor on the second set bit, the voltage between the live line L and the equipment terminal PE1 is equal to the voltage between the equipment terminal PE1 and the neutral line N. And, the voltage between the live line L and the equipment terminal PE1 is equal to one half of the voltage between the live line L and the neutral line N.
Referring to fig. 2, a second embodiment of the present utility model is described in detail below with reference to fig. 2. When the circuit adopts double fire wires to supply power, the circuit system is provided with a plurality of fire wires and ground wires. I.e. the circuitry does not use or there is no null line in the circuitry, the circuitry employs the scheme of the second embodiment to detect if the PE line is well connected. In a second embodiment, the present utility model provides a wiring structure 20 with a detection circuit, the wiring structure 20 with a detection circuit being provided with a plurality of live, ground wires 24. The wiring structure 10 with the detection circuit comprises a first live wire L1, a second live wire L2, a third detection module 21, a fourth detection module 22 and a measurement module 23. The first live wire L1 is any live wire, the second live wire L2 is any live wire different from the first live wire L1, and the pressure difference between the first live wire L1 and the second live wire L2 in the multiple live wires is the largest. Further, when the equipment terminal PE3 and the ground terminal PE3 are disconnected, the resistor on the third detection module 21 performs a voltage dividing operation on the voltage between the first live line L1 and the second live line L2. Therefore, the difference between the first voltage and the second voltage measured by the measuring module 23 will be relatively large. Therefore, the measurement module 23 can better compare the first voltage with the second voltage, so that the detection module can more accurately judge whether the PE wires are well connected.
The third detection module 21 comprises a third setting bit which can be used to set the resistance. The fourth detection module 22 includes a fourth set bit that can be used to set a resistance. The ground wire 24 is provided with a device end PE3 and a ground end PE4. The third detection module is connected between the first live wire L1 and the equipment end PE3, the fourth detection module 22 is connected between the second live wire L2 and the equipment end PE3, and the measurement module 23 can be used for detecting the voltage of the equipment end. When the third setting bit is provided with the third resistor and the fourth setting bit is provided with the fourth resistor, the voltage of the device terminal PE3 is the first voltage. Wherein the third resistor and the fourth resistor have different impedances. When the third setting bit is provided with the fourth resistor and the fourth setting bit is provided with the third resistor, the voltage of the device terminal PE3 is the second voltage. Based on the difference between the first voltage and the second voltage, the measurement module 23 determines whether the device side and the ground side are connected on or disconnected. The measuring module 23 comprises a voltmeter for measuring the first voltage and the second voltage and a detection chip for determining whether the PE line is well connected based on the first voltage and the second voltage. Wherein the PE line is the ground line connecting the device to the ground.
Therefore, a user can timely judge whether the ground wire of the equipment is well connected. Therefore, when the ground wire is poor in wiring, a user can repair in time so as to remove faults. The technical problem that the PE line and the grounding point of the existing equipment are prone to breaking faults is effectively solved. The user can effectively avoid leakage accidents by using the wiring structure detection circuit with the detection circuit. Thus, the user is safer to use the electrical devices in the industry.
In this embodiment, the user may set the resistor at the third setting bit of the third detection module 21, and the user may set the resistor at the fourth setting bit of the fourth detection module 22. In the case of good connection of the PE lines, since the equipment terminal PE3 and the ground terminal PE4 are at the same potential, the voltage between the first live line L1 and the ground terminal PE4 is equal to the voltage between the first live line L1 and the equipment terminal PE 3. Since the voltage between the first live wire L1 and the ground terminal PE4 does not change, even if resistances with different impedances are provided between the first live wire L1 and the ground terminal PE4, the voltage between the first live wire L1 and the equipment terminal PE3 does not change, i.e. the first voltage is equal to the second voltage. When the PE wiring is bad, the grounding end is disconnected from the PE wire of the equipment. At this time, the ground terminal PE4 and the device terminal PE3 are not at the same potential, and current flows from the first line L1 to the second line L2 through the resistor. Meanwhile, the resistor on the third setting bit and the resistor on the fourth setting bit can perform voltage division operation on the voltage between the first live wire L1 and the second live wire L2. Thus, the voltage between the first hot line L1 and the device terminal PE3 is related to the resistance of the resistor on the third set bit. If resistances with different impedances are set between the first live wire L1 and the equipment end PE3, and the impedance of the resistance between the second live wire L2 and the equipment end PE3 is kept unchanged, the first voltage is not equal to the second voltage. Therefore, if the measurement module 23 detects that the difference between the first voltage and the second voltage is equal to 0, the measurement module 23 determines that the device PE3 and the ground PE4 are connected and turned on. If the detecting module detects that the difference between the first voltage and the second voltage is not 0, the measuring module 23 may determine that the device end PE3 and the ground end PE4 are disconnected.
As shown in fig. 2, the third setting bit is provided with a plurality of resistors, and the plurality of resistors on the third setting bit are connected in series. And, the user may change a different resistance at the third set point. The fourth setting bit is provided with a plurality of resistors, and the plurality of resistors on the fourth setting bit are connected in series. The user can also change a different resistor at the fourth setting bit. For example, the user replaces the resistor with a different resistance value at the third set bit, and the resistance of the resistor at the fourth set bit remains unchanged. Thus, based on the change in the device side voltage, the measurement module 23 may determine whether the device side PE3 and the ground side PE4 are connected on or disconnected. For example, the resistance of the resistor on the third set bit remains unchanged, and the user replaces the resistor of a different resistance value at the fourth set bit. Thus, based on the change in the device side voltage, the measurement module 23 may determine whether the device side PE3 and the ground side PE4 are connected on or disconnected.
As shown in fig. 2, when the device terminal PE3 and the ground terminal PE4 are disconnected, the resistor on the third setting bit and the resistor on the fourth setting bit may perform a voltage dividing operation on the voltage between the first live line L1 and the second live line L2. The voltage divided by the resistance of the third set bit and the resistance of the fourth set bit is positively correlated with the resistance of the resistance. Therefore, when the connection between the device end PE3 and the ground end PE4 is broken, if the resistance of the resistor on the third setting bit is greater than the resistance of the resistor on the fourth setting bit, the voltage between the first live line L1 and the device end PE3 is greater than the voltage between the device end PE3 and the second live line L2. When the equipment end PE3 and the ground end PE4 are disconnected, if the impedance of the resistor on the third set bit is smaller than the impedance of the resistor on the fourth set bit, the voltage between the first live wire L1 and the equipment end PE3 is smaller than the voltage between the equipment end PE3 and the second live wire L2. When the connection between the equipment terminal PE3 and the ground terminal PE4 is disconnected, if the impedance of the resistor on the third set bit is equal to the impedance of the resistor on the fourth set bit, the voltage between the first live line L1 and the equipment terminal PE3 is equal to the voltage between the equipment terminal PE3 and the second live line L2. Therefore, the connection structure 20 with the detection circuit can better judge whether the PE wires in the multi-live wire circuit are well connected. And, the wiring structure 20 with the detection circuit is compatible with single-fire and multi-fire circuits. Since the user can determine whether the PE line is well connected only by setting the resistor, it is simple for the user to implement the wiring structure with detection circuit 10, and the detection result of the wiring structure with detection circuit 20 is also reliable.
The working principle of the utility model is as follows: when a user detects a circuit with a single live wire, the user connects the first detection module 11 between the live wire L and the equipment end PE1, and the second detection module 12 between the neutral wire N and the equipment end PE 1. Then, the user sets the first resistance on the first setting bit, and the user sets the second resistance on the second setting bit. The user may set one or more resistors on the first set point and the user may set one or more resistors on the second set point. Wherein the impedance of the first resistor is different from the impedance of the second resistor. Next, the user measures the voltage at the device PE1 at this time as the first voltage through the measurement module 13. Subsequently, the user sets the second resistance on the first setting bit, and the user sets the first resistance on the second setting bit. Then, the user measures the voltage at the device PE1 at this time as the second voltage through the measurement module 13. If the measurement module 13 detects that the difference between the first voltage and the second voltage is equal to 0, the measurement module 13 may determine that the device PE1 and the ground PE2 are connected and turned on. If the measurement module 13 detects that the difference between the first voltage and the second voltage is not 0, the measurement module 13 may determine that the device PE1 and the ground PE2 are disconnected.
When the user detects the circuit of many live wires, the user can select two live wires earlier, and these two live wires are first live wire L1 and second live wire L2. Wherein the first line L1 and the second line L2 have the largest pressure difference among the plurality of lines. Then, the user connects the third detection module 21 between the first live wire L1 and the equipment end PE3, and the fourth detection module 22 between the second live wire L2 and the equipment end PE 3. Then, the user sets the third resistance on the third setting bit, and the user sets the fourth resistance on the fourth setting bit. The user may set one or more resistors on the third setting bit and the user may set one or more resistors on the fourth setting bit. Wherein the impedance of the third resistor is different from the impedance of the fourth resistor. Next, the user measures the voltage at the device PE3 at this time as the first voltage through the measurement module 23. Subsequently, the user sets the fourth resistance on the third setting bit, and the user sets the third resistance on the fourth setting bit. Then, the user measures the voltage at the device PE3 at this time as the second voltage through the measurement module 23. If the measurement module 23 detects that the difference between the first voltage and the second voltage is equal to 0, the measurement module 23 may determine that the device PE3 and the ground PE4 are connected and turned on. If the measurement module 23 detects that the difference between the first voltage and the second voltage is not 0, the measurement module 23 may determine that the device end PE3 and the ground end PE4 are disconnected.

The wiring structure with the detection circuit further comprises a first detection module, a second detection module and a measurement module, wherein the first setting bit of the first detection module and the second setting bit of the second detection module can be used for setting resistance. The first detection module is connected between equipment ends of the live wire and the ground wire, the second detection module is connected between equipment ends of the zero wire and the ground wire, and the measurement module is used for detecting voltage of the equipment ends. When the first setting bit is provided with a first resistor and the second setting bit is provided with a second resistor, the voltage of the equipment terminal is a first voltage. Wherein the impedance of the first resistor is different from the impedance of the second resistor. When the first setting bit is provided with the second resistor and the second setting bit is provided with the first resistor, the voltage of the equipment terminal is the second voltage. Based on the difference between the first voltage and the second voltage, the measurement module determines whether the device terminal and the ground terminal are connected on or disconnected.
