Description

Technical Field

[0001] This invention relates to the field of power system monitoring technology, and in particular to a clamp-on voltage sensor and its lightning protection control method. Background Technology

[0002] In existing power measurement systems, the voltage of transmission cables can be measured by inducing the electric field of the transmission cable using an electric field modulation plate. However, during broadband signal acquisition, the electric field signal is susceptible to electromagnetic interference, its own vibration, and changes in the relative position of the transmission cable and the electric field modulation plate, resulting in poor measurement accuracy. To achieve accurate voltage signal measurement, voltage sensors are often installed on outdoor transmission cables. However, these cables are easily damaged by lightning strikes during thunderstorms. Replacing damaged sensors significantly increases labor intensity and system operating costs. Summary of the Invention

[0003] To address the above shortcomings, this invention provides a clamp-on voltage sensor and its lightning protection control method, which can effectively reduce lightning strikes. The specific technical solution is as follows: A clamp-on voltage sensor includes: a first housing, a second housing hinged to the first housing, both the first and second housings having semi-circular grooves for engaging transmission wires, the two semi-circular grooves forming a circular groove when the first and second housings are closed, the first and second housings being fitted together with a snap-fit ​​structure for engaging the first and second housings, and a voltage measuring component and a power-taking component installed inside the first and second housings, the power-taking component supplying power to the voltage measuring component.

[0004] Preferably, the power-collecting component includes a semi-annular electromagnetic core, and a power-collecting coil is sleeved on the electromagnetic core inside the first housing. When the first housing and the second housing are closed, the two electromagnetic cores and the power-collecting coil form a CT power-collecting ring, and the output end of the power-collecting coil is connected to the control circuit board.

[0005] Preferably, both ends of the first housing and the second housing are provided with vertically opened mounting grooves, and a limiting component is provided in the mounting groove; the limiting component includes a sliding limiting block arranged in the vertical direction, one side of the sliding limiting block is an arc-shaped groove, and when the first housing and the second housing are fastened together, the line connecting the edges of the two arc-shaped grooves forms a convex ring, and a first limiting spring is provided between the sliding limiting block and the bottom end of the mounting groove.

[0006] Preferably, the mounting groove is further provided with a top rod that slides vertically. The top rod is fitted with a second limiting spring. One end of the second limiting spring is a limiting plate that is laterally connected to the middle of the mounting groove, and the end face of the other end contacts a ring platform that is fixedly connected to the top rod. The top end of the top rod extends out of the upper end face of the first housing or the second housing, and the lower part of the top rod extends out of the limiting plate.

[0007] Preferably, a cable is provided between the bottom end of the top rod and the bottom end of the sliding limit block, and a guide wheel for guiding the cable is provided on the bottom surface of the mounting groove.

[0008] Preferably, the control circuit board includes a protection module for protecting the circuit. The output terminal of the protection module is connected to a control switch S1 for connecting to the power supply circuit. A control switch S2 is connected between the power supply circuit and the backup power supply. The power supply circuit converts the output of the protection module into a stable power supply to power the voltage measurement component. The backup power supply powers the voltage measurement component when the control switch S1 is open.

[0009] Preferably, the protection module is equipped with a short-circuit switch. When the short-circuit switch is closed, it performs short-circuit control on the power-taking coil, causing the two power-taking cores to lose their magnetic force.

[0010] Preferably, the voltage measurement component includes a power frequency modulation module, an electric field modulation board, an electric field sensing chip, a voltage signal sampling module, a voltage modulation module, an MCU microprocessor, and a remote communication module. The electric field modulation board is semi-circular and disposed inside the semi-circular groove of the first housing. During voltage measurement, the electric field modulation board is coaxially arranged with the transmission wire. The electric field around the transmission wire is converted into a modulated electric field signal through the synergistic effect of the electric field modulation board and the power frequency modulation module, and the electric field signal is transmitted to the voltage signal sampling module through the electric field sensing chip.

[0011] Preferably, the voltage modulation module is used to modulate the sampling signal of the voltage signal sampling module, and the voltage modulation module is connected to the MCU microprocessor. The remote communication module transmits the modulated signal to the remote central control platform.

[0012] A lightning strike protection control method, based on a clamp-on voltage sensor, comprises the following steps: S1: Collect weather forecast data through weather forecasts, and predict whether there will be thunderstorms in the next unit period based on the weather forecast data, wherein the unit period is one day; If yes, proceed to step S2; otherwise, proceed to step S3. S2: Control switch S1 is open and short-circuit switch is closed, the two power-taking coils are short-circuited, causing the two power-taking cores to lose their magnetic force, control switch S3 is closed, the backup power supply supplies power to the voltage measurement component, and proceeds to step S4; S3: Detect whether a voltage measurement command has been received: If not, continue to detect the measurement command and close the control switch S2 to charge the backup battery; if yes, proceed to step S5. S4: Check if a voltage measurement command has been received: If not, continue to check for the measurement command; if yes, proceed to step S5. S5: The voltage sampling module acquires the voltage signal, and the sampled signal is modulated and transmitted to the MCU microprocessor; S6: The remote communication module transmits the sampled and modulated signal to the remote central control platform.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention, by setting a limiting component, initially ensures that the top surface of the arc-shaped groove of the sliding limiting block is flush with the top surface of the semi-circular groove, which does not affect the insertion of the transmission wire. When the first housing and the second housing are fastened together, the transmission wire is automatically clamped, and its relative position is fixed, thus avoiding measurement errors caused by factors such as shaking during the measurement process and greatly improving the measurement accuracy.

[0014] This invention improves the stability of the measurement system by clamping the clamp-on voltage sensor to prevent it from sliding on the transmission line.

[0015] This invention is ingeniously designed. By setting a cable between the top rod and the sliding limit block, the linkage between the sliding limit block and the cable can be realized. At the same time, the compression force of the second limit spring is greater than that of the first limit spring, and the second limit spring has a tendency to reset, causing the top rod to rise upward. The cable pulls the sliding limit block downward, making the arc-shaped groove at the top of the sliding limit block flush with the semi-circular groove, which facilitates the placement of power transmission cables.

[0029] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Furthermore, the technical features involved in the different embodiments of this invention described below can be combined with each other as long as they do not conflict with each other.

[0030] Example 1: Reference Figures 1-8 This invention provides a clamp-on voltage sensor, comprising: a first housing 1, with a second housing 2 hinged to the first housing 1; both the first housing 1 and the second housing 2 have semi-circular grooves 4 for engaging a transmission wire 3; when the first housing 1 and the second housing 2 are closed, the two semi-circular grooves 4 form a circular groove; the first housing 1 and the second housing 2 are fitted together with a snap-fit ​​structure 5 for engaging with each other; a voltage measuring component and a power-supply component are installed inside the first housing 1 and the second housing 2, with the power-supply component supplying power to the voltage measuring component. The arrangement of the first housing 1 and the second housing 2 allows the transmission wire 3 to be placed inside the first housing 1 and the second housing 2, effectively preventing the sensor from directly contacting the outside. Simultaneously, the first housing 1 and the second housing 2 are connected to each other via the snap-fit ​​structure 5, facilitating opening and replacement of the sensor; and the voltage measuring component enables voltage measurement.

[0031] Reference Figures 6-7 The power-collecting assembly includes a semi-circular electromagnetic core 6. A power-collecting coil 7 is fitted on the electromagnetic core 6 inside the first housing 1. When the first housing 1 and the second housing 2 are closed, the two electromagnetic cores 6 and the power-collecting coil 7 form a CT power-collecting ring. The output end of the power-collecting coil 7 is connected to the control circuit board 8.

[0032] In this embodiment, preferably, the transmission wire 3 is a live cable; the control circuit board 8 is used to control the power supply of the power coil 7. During current and voltage detection, the clamp-type voltage sensor is clipped to the transmission wire 3 to be measured through the first housing 1 and the second housing 2. The CT power supply ring magnetically inductions the transmission wire 3, and the control circuit board 8 completes the detection of voltage and current of the transmission wire 3.

[0033] Reference Figure 4 The first housing 1 and the second housing 2 are provided with vertically opened mounting grooves at both ends, and a limiting component is provided in the mounting groove. The limiting component includes a sliding limiting block 9 arranged in the vertical direction. One side of the sliding limiting block 9 is an arc-shaped groove. When the first housing 1 and the second housing 2 are fastened together, the line connecting the edges of the two arc-shaped grooves forms a convex ring. A first limiting spring 10 is provided between the sliding limiting block 9 and the bottom end of the mounting groove. With the above structure, during current and voltage measurement, since the transmission wire 3 has various wire diameters, the radius of the semi-circular groove 4 is often set to be relatively large to meet the measurement requirements of various transmission wire 3 models. However, when the larger semi-circular groove 4 is fitted onto the outside of the smaller transmission wire 3, the relative position of the transmission wire 3 is easily unstable under external forces, such as strong winds or other severe weather, resulting in low measurement accuracy. With this setting, the sliding limit block 9 can accommodate various transmission wire 3 models through sliding. At the same time, the first limit spring 10 can apply force to the sliding limit block 9, so that the two sliding limit blocks 9 tend to move closer to each other, thereby clamping the transmission wire 3.

[0034] Preferably, the radius of the arc-shaped groove and the radius of the semi-circular groove 4 are the same. In this embodiment, the radius of the arc-shaped groove is further limited to be the same as the radius of the semi-circular groove 4, so that the edge of the arc-shaped groove of the sliding limit block can coincide with the inside of the semi-circular groove 4.

[0035] Reference Figure 1 and Figure 2 The mounting groove is also equipped with a vertically sliding top rod 11. A second limiting spring 14 is sleeved on the top rod 11. One end of the second limiting spring 14 is a limiting plate 12 horizontally connected to the middle of the mounting groove, and the other end of the spring contacts an annular platform 13 fixedly connected to the top rod 11. The top end of the top rod 11 extends out of the upper end face of the first housing 1 or the second housing 2, and the lower part of the top rod 11 extends out of the limiting plate 12. In this embodiment, the top rod 11 is configured to cooperate with the second limiting spring 14 to separate the first housing 1 and the second housing 2. The limiting plate 12 is configured to restrict the lower side of the second limiting spring 14. When the top rod 11 is pressed and moves downward, the annular platform 13 moves downward with the top rod 11, squeezing the second limiting spring 14. The second limiting spring 14 has a tendency to return to its original position. When the first housing 1 and the second housing 2 are separated, the end of the top rod 11 pushes the second housing 2 out.

[0036] A cable 15 is provided between the bottom end of the top rod 11 and the bottom end of the sliding limit block 9. A guide wheel 16 for guiding the cable 15 is provided on the bottom surface of the mounting groove. In this embodiment, the linkage between the sliding limit block 9 and the top rod 11 can be realized through this arrangement. At the initial moment, the upper end surface of the ring platform 13 abuts against the upper end surface of the inner side of the mounting groove. The first limit spring 10 and the second limit spring 14 are both in a compressed state, and the compression force of the second limit spring 14 is greater than that of the first limit spring 10, so that the arc-shaped groove at the top of the sliding limit block 9 is flush with the semi-circular groove 4. When the first housing 1 and the second housing 2 are fastened, the upper end surface of the first housing 1 abuts against the top rod 11 on the second housing 2, and the upper end surface of the second housing 2 abuts against the top rod 11 on the first housing 1, so that the top rod 11 moves downward, and the second limit spring 14 continues to compress. Under the action of the first limit spring 10, the sliding limit block 9 is pushed out to clamp the transmission wire 3.

[0037] Furthermore, the push rods 11 on the first housing 1 and the second housing 2 are staggered, meaning that the axes of the push rods 11 on the first housing 1 and the second housing 2 do not coincide after the first housing 1 and the second housing 2 are fastened together. In this embodiment, with this arrangement, when the first housing 1 and the second housing 2 are fastened together, the push rods 11 can be staggered and will not overlap with each other.

[0038] By setting a limiting component, initially, the arc groove of the sliding limiting block 9 is flush with the top surface of the semi-circular groove 4, which does not affect the insertion of the transmission wire 3. When the first housing 1 and the second housing 2 are fastened together, the transmission wire 3 is automatically clamped, and its relative position is fixed, avoiding measurement errors caused by shaking and other factors during the measurement process, greatly improving the measurement accuracy. At the same time, the clamping prevents the clamped voltage sensor from sliding on the transmission wire 3, improving the stability of the measurement system.

[0039] The control circuit board 8 includes a protection module for protecting the circuit. The output of the protection module is connected to a control switch S1 for connecting to the power supply circuit. A control switch S2 is connected between the power supply circuit and the backup power supply. The power supply circuit converts the output of the protection module into a stable power supply to power the voltage measurement component. The backup power supply powers the voltage measurement component when the control switch S1 is open.

[0040] The protection module is equipped with a short-circuit switch. When the short-circuit switch is closed, it short-circuit controls the power extraction coil 7, causing the two electromagnetic cores 6 to lose their magnetic force. In thunderstorms, this effectively prevents damage to the sensor or power transmission cable 3 in the event of a lightning strike.

[0041] The voltage measurement component includes a power frequency modulation module, an electric field modulation board 17, an electric field sensing chip, a voltage signal sampling module, a voltage modulation module, an MCU microprocessor, and a remote communication module. The electric field modulation board 17 is semi-circular and is disposed inside the semi-circular groove 4 of the first housing 1. During voltage measurement, the electric field modulation board 17 is coaxially arranged with the transmission wire 3. The electric field around the transmission wire 3 is converted into a modulated electric field signal through the synergistic effect of the electric field modulation board 17 and the power frequency modulation module, and then transmitted to the voltage signal sampling module through the electric field sensing chip. This process utilizes the inductive characteristics of the electric field and can complete the "non-destructive acquisition" of voltage information without direct contact with the charged conductor. The voltage modulation module modulates the sampling signal of the voltage signal sampling module. The voltage modulation module, along with the MCU microprocessor and remote communication module, transmits the modulated signal to a remote central control platform. In this embodiment, the device achieves self-powering of the sensor by magnetically coupling the CT power-taking ring with the transmission wire 3. Voltage measurement of the transmission wire 3 is achieved by electric field coupling the electric field modulation board 17 with the transmission wire 3, significantly reducing the cost of voltage measurement.

[0042] Example 2: Reference Figures 1-10 The lightning protection control method, based on a clamp-on voltage sensor, includes the following steps: S1: Collect weather forecast data through weather forecasts, and predict whether there will be thunderstorms in the next unit period, with the unit period being one day; If yes, proceed to step S2; otherwise, proceed to step S3. S2: Control switch S1 is open and short-circuit switch is closed, the two power-taking coils 7 are short-circuited, causing the two power-taking cores 6 to lose their magnetic force, control switch S3 is closed, the backup power supply supplies power to the voltage measurement component, and proceeds to step S4; S3: Detect whether a voltage measurement command has been received: If not, continue to detect the measurement command and close the control switch S2 to charge the backup battery; if yes, proceed to step S5. S4: Check if a voltage measurement command has been received: If not, continue to check for the measurement command; if yes, proceed to step S5. S5: The voltage sampling module acquires the voltage signal, and the sampled signal is modulated and transmitted to the MCU microprocessor; S6: The remote communication module transmits the sampled and modulated signal to the remote central control platform.

[0043] In this embodiment, the current and voltage measurement commands are automatically generated by the MCU microprocessor sampling time interval or actively issued by the central control platform. This device collects weather data and supplies power to the system through a backup battery during thunderstorms. It also short-circuits the power extraction coil to make the electromagnet core lose its magnetic force, which greatly improves the safety and reliability of the system. At the same time, the backup power supply meets the voltage detection requirements of the power transmission cable 3 under severe weather conditions.

[0044] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
