Description

Technical Field

[0001] The present invention relates to the technical field of mutual inductors, and in particular to a novel quantum current mutual inductor. Background Art

[0002] With the development of power technology, the advancement of smart grids, and the large-scale integration of renewable energy generation, the accuracy, stability, and adaptability of current measurement are facing unprecedentedly high demands. While quantum current transformers, as an emerging technology, have shown potential for high-precision current measurement, they still face numerous challenges in practical application. Accurate current measurement is crucial to the safe and stable operation of smart grids. It not only prevents overloads, improves energy efficiency, but also facilitates the effective integration of renewable energy.

[0003] However, when the current in the circuit changes dramatically in an instant, such as the surge current generated during the startup of a high-power motor, this type of transient current changes quickly and has a high intensity, exceeding the standard operating range considered when designing the quantum current transformer, resulting in deviations in its measurement results. In addition, surge current not only means a sudden increase in current intensity, but is also accompanied by electromagnetic interference (EMI) and noise. These additional electromagnetic activities will affect the sensitive components inside the quantum current transformer, thereby interfering with the normal signal acquisition process and reducing measurement accuracy. This deviation will affect the accuracy of subsequent decisions made based on current data, and thus affect the operating efficiency and safety of the power system. Summary of the Invention

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0019] Example 1 This embodiment discloses a novel quantum current transformer for monitoring the current state in an electric wire.

[0020] A new type of quantum current transformer, referring to Figure 1-Figure 4 As shown, it includes a shell 1, in which a coil structure 3, a processing unit 4 and a first shielding layer 5 are installed. The processing unit 4 is provided with a connection terminal, and the connection terminal of the processing unit 4 is connected to a wire so that the processing unit 4 is electrically connected to the remote control terminal through the Internet of Things, wherein the first shielding layer 5 is located outside the coil structure 3; the shell 1 is fixed with two symmetrically distributed first fixed shells 6, and the first fixed shell 6 on the left is fixed with a second shielding layer 7 (attached) Figure 4 Taking the middle direction as an example), four iron rings are arranged on the second shielding layer 7 at equal intervals, and the second shielding layer 7 is wavy, so that the second shielding layer 7 can be folded evenly and the folded second shielding layer 7 is located in the first fixed shell 6 on the left side (with the attached Figure 4 The following directions are based on the directions in the attached Figure 4 Taking the middle direction as an example), the iron ring on the second shielding layer 7 is slidably connected to the shell 1 and the first fixed shell 6 on the right side. A magnetic driving component 8 is fixed in the first fixed shell 6. The magnetic driving component 8 is an electromagnetic coil. When powered, it becomes a magnet for attracting the iron ring on the second shielding layer 7 and controlling the iron ring on the second shielding layer 7 to move right or left, so that the second shielding layer 7 becomes an expanded state or a folded state. The magnetic driving component 8 is electrically connected to the remote control terminal through the Internet of Things.

[0021] The above setting can be achieved so that when the mutual inductor is not in use, the second shielding layer 7 and the first shielding layer 5 in the unfolded state wrap the coil structure 3 to prevent external electromagnetic changes from affecting the operation of the device. At the same time, when the device is installed, the unfolded state of the second shielding layer 7 prevents the mutual inductor from monitoring the wires connected to the motor and the surge current in the wires caused by the motor starting up interferes with the working accuracy of the mutual inductor. After the motor is working normally, the second shielding layer 7 is controlled to become a folded state, so that the mutual inductor can monitor the current normally.

[0022] The working process of the mutual inductor in this embodiment is as follows: Installation process: When monitoring the electric wires whose current needs to be monitored, the transformer is installed at the designated position, and then the measured electric wire is passed through the middle of the shell 1 to complete the installation operation, and the wires are connected to the connection terminals of the processing unit 4 to facilitate the transmission of the detected data to the remote control terminal.

[0023] Usage process: If a motor is installed on the wire (a device that can cause surge current, if real-time monitoring is required, other types of mutual inductors can be installed on the wire, this device is only used to measure the current in the wire relatively accurately), since the second shielding layer 7 is in the expanded state in the initial state, as shown in the attached Figure 4 After the motor is started, the left magnetic drive element 8 is started by the remote control terminal (with the attached Figure 4 Taking the middle direction as an example), the iron ring on the second shielding layer 7 is controlled to move to the left, so that the second shielding layer 7 becomes a folded state (the folded second shielding layer 7 is completely located in the first fixed shell 6 on the left). The subsequent coil structure 3 and the processing unit 4 work together to monitor the current in the wire. If the device does not need to be monitored, the magnetic drive component 8 on the right is started through the remote control terminal (with the attached Figure 4 Taking the middle direction as an example), the iron ring on the second shielding layer 7 is controlled to move rightward, so that the second shielding layer 7 becomes an expanded state to protect the device.

[0024] Example 2 The novel quantum current transformer disclosed in this embodiment, based on the first embodiment, further has the function of ensuring that the wire is centered.

[0025] Reference Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, it also includes: two threaded sleeves 9, which are respectively arranged on adjacent first fixed shells 6; two rotating shells 10, which are respectively threadedly connected to adjacent threaded sleeves 9, and the rotating shell 10 is limitedly slidably connected with four sliding blocks 11 distributed equidistantly in the circumferential direction, and the facing sides of the four adjacent sliding blocks 11 are provided with rubber protrusions. A first elastic member 12 is installed between the sliding block 11 and the adjacent rotating shell 10, and the first elastic member 12 is a tension spring, and it is always in a stretched state. The sliding block 11 is provided with a first inclined surface, and the first fixed shell 6 is provided with a second inclined surface. The second inclined surface on the first fixed shell 6 is used to squeeze the first inclined surfaces of the four adjacent sliding blocks 11, so that the four adjacent sliding blocks 11 are close to each other.

[0026] The working process of this embodiment is similar to that of the first embodiment and is described in detail as follows: After the wire is passed through the housing 1, the rotating shell 10 is rotated and the rotating shell 10 moves along the threads on the adjacent threaded sleeve 9, so that the rotating shell 10 drives the four adjacent sliding blocks 11 to move toward the housing 1, wherein the four adjacent sliding blocks 11 are squeezed by the second inclined surface on the corresponding first fixed shell 6, and the four sliding blocks 11 are synchronously moved closer to each other, that is, the four sliding blocks 11 clamp the wire in the housing 1 in the center, ensuring that the wire remains centered in the housing 1, thereby ensuring the measurement accuracy of the device.

[0027] Example 3 The novel quantum current transformer disclosed in this embodiment, based on the second embodiment, further has the function of ensuring that the wires in the monitoring section remain straight.

[0028] Reference Figure 3 、 Figure 5 and Figure 6 As shown, it also includes: two first limiting rings 13, respectively fixed to adjacent threaded sleeves 9, the threaded sleeves 9 are rotatably connected to the adjacent first fixed shells 6, and a second elastic member 15 is installed between the threaded sleeves 9 and the shell 1, the second elastic member 15 is a spring, the second elastic member 15 is in contact with the shell 1 and the adjacent threaded sleeves 9, and the second elastic member 15 is located on the outside of the adjacent first fixed shells 6; two second limiting rings 14, both fixed to the shell 1, the first limiting ring 13 and the second limiting ring 14 are both provided with notches equidistantly distributed circumferentially, when the first limiting ring 13 and the second limiting ring 14 are in contact, the two engage with each other, at this time the second limiting ring 14 and the adjacent first limiting ring 13 will be in a limiting state, and the minimum distance between the first limiting ring 13 and the second limiting ring 14 is greater than twice the maximum depth of its own notch.

[0029] The working process of this embodiment is similar to that of the second embodiment and is described in detail as follows: During the operation of centering the wire, the rotating shell 10 on the left is pushed first. The rotating shell 10 on the left engages the adjacent first limit ring 13 with the corresponding second limit ring 14 through the adjacent threaded sleeve 9. At the same time, the corresponding second elastic member 15 is compressed. Then the operator rotates the rotating shell 10 on the left to move the rotating shell 10 toward the direction close to the shell 1. After that, the four adjacent sliding blocks 11 are brought together to center clamp the wire. After completing the clamping operation of the wire, the rotating shell 10 is released. Under the elastic action of the second elastic member 15, the rotating shell 10 moves in the opposite direction. At this time, the separation of the first limit ring 13 and the adjacent second limit ring 14 prevents the rotation of the sliding block 11 from accidentally touching the four sliding blocks 11 to release the center clamping of the wire.

[0030] After the sliding block 11 on the left completes clamping the wire, the above operation is repeated so that the four sliding blocks 11 on the right clamp the wire in the center, and then the rotating shell 10 on the right is released. At this time, under the elastic action of the second elastic member 15 on the right, the rotating shell 10 on the right and the four adjacent sliding blocks 11 have a movement tendency away from the shell 1. This movement tendency causes the left and right groups of sliding blocks 11 to stretch the clamped wires, ensuring that the wires remain straight, further ensuring the accuracy of the measurement results of the device.

[0031] Example 4 The novel quantum current transformer disclosed in this embodiment, based on the third embodiment, further has the function of adaptively adjusting the position of the connection terminal.

[0032] Reference Figure 2 and Figure 7 As shown, a support member 2 is also included, and the support member 2 is used for the shell 1 to be in an active state. The support member 2 includes a fixing frame 201, and the fixing frame 201 is composed of a horizontal plate and a cover plate. The horizontal plate on the fixing frame 201 is provided with a plurality of horizontal holes for bolts to pass through, so that the device can be installed and fixed in a specified position. The fixing frame 201 is provided with a fixing block 202, and the fixing block 202 is rotatably provided with a rotating frame 203. The rotating frame 203 is rotatably connected to the shell 1, and there is rotational damping between the rotating frame 203 and the shell 1.

[0033] The working process of this embodiment is the same as that of embodiment 3, and is described in detail as follows: After the bolts are passed through the horizontal holes of the horizontal plate on the fixing frame 201 to complete its installation and fixation, the housing 1 is controlled to rotate circumferentially (rotate in the horizontal direction) so that the central axis of the housing 1 coincides with the central axis of the wire, further ensuring the measurement accuracy. At the same time, the rotation of the housing 1 in the vertical direction changes the position of the connecting terminal on the processing unit 4, making it easier to connect the wire to the connecting terminal on the processing unit 4.

[0034] Example 5 The novel quantum current transformer disclosed in this embodiment, based on the fourth embodiment, further has the function of buffering the vibrations suffered by the device.

[0035] Reference Figure 2 and Figure 7As shown, the support member 2 also includes four sliding plates 16 distributed circumferentially, and the four sliding plates 16 are all slidably connected to the fixed frame 201. The fixed block 202 is slidably connected to the fixed frame 201. The fixed block 202 is composed of a rectangular plate and a cylinder, wherein the four sliding plates 16 are in contact with the four sides of the rectangular plate on the fixed block 202, and two third elastic members 17 are installed between the sliding plates 16 and the fixed frame 201 (the number is the number shown in the accompanying drawings, and the time number can be set according to needs), the third elastic member 17 is a spring, and the third elastic member 17 is always in a compressed state.

[0036] The working process of this embodiment is the same as that of the fourth embodiment, and is described in detail as follows: After the vibration generated by an earthquake or a passing car is transmitted to the device, the device as a whole shakes. Since the rotating frame 203 and the fixed block 202 are in a relatively active state with the fixed frame 201, the rotating frame 203 and the fixed block 202 shake relative to the fixed frame 201. The shaking of the fixed block 202 squeezes the corresponding sliding plate 16 to move and causes the third elastic member 17 on the corresponding side to deform. The deformation of the third elastic member 17 converts the vibration energy into elastic potential energy, which buffers and consumes the vibration force. If the wires in the shell 1 are in a suspended state and are blown by the external wind, the wires shake. The shaking of the wires causes relative sliding between the rotating frame 203 and the fixed frame 201 through the connected parts. Subsequently, the above operation is repeated and the third elastic member 17 performs buffering protection to reduce the friction between the wires and the device. The mechanism in the embodiment is an optional part. If the above state does not occur, a basic ordinary support plate can be used.

[0037] Example 6 The novel quantum current transformer disclosed in this embodiment, based on the fifth embodiment, further has the function of reducing shaking.

[0038] Reference Figure 7 and Figure 8As shown, the support member 2 also includes a second fixed shell 18, which is fixed to the rotating frame 203. The middle part of the second fixed shell 18 is sealed and rotatably connected to a rotating ring 19 fixed to the fixed block 202. The rotating ring 19 is provided with a step surface, and the step surface of the rotating ring 19 contacts the second fixed shell 18 to improve the sealing between the rotating ring 19 and the second fixed shell 18. The rotating ring 19 and the second fixed shell 18 form a sealed chamber filled with a liquid medium. The rotating ring 19 is fixed with four first fixed plates 20 distributed equidistantly in the circumferential direction; the second fixed shell 18 is fixed with four second fixed plates 21 distributed equidistantly in the circumferential direction. When the first fixed plate 20 is aligned with the second fixed plate 21, the two do not contact, that is, during the relative rotation of the second fixed shell 18 and the rotating ring 19, the first fixed plate 20 and the second fixed plate 21 will not contact each other; the first fixed plate 20 and the second fixed plate 21 are both provided with three through holes for the passage of the liquid medium.

[0039] The working process of this embodiment is the same as that of embodiment 5, and is described in detail as follows: When the wires in the shell 1 are in a suspended state, the shaking of the wires will cause the shell 1 to swing through the connected parts. The shaking of the wires will drive the shell 1 to rotate in the horizontal direction through the connected parts. The shell 1 drives the rotating frame 203 and the second fixed shell 18 to rotate, so that the second fixed shell 18 and the rotating ring 19 rotate relative to each other. At the same time, the first fixed plate 20 and the second fixed plate 21 rotate relative to each other. The relative rotation of the first fixed plate 20 and the second fixed plate 21 will alternately stir the liquid medium in the sealed chamber. The liquid medium passes through the through holes on the first fixed plate 20 and the second fixed plate 21. The liquid resistance in this process will consume the vibration potential energy of the relative rotation of the first fixed plate 20 and the second fixed plate 21, that is, the shaking degree of the wires is weakened.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly.
