Description

Technical Field

[0001] This invention relates to a fault indicator, and more particularly to a non-contact measurement fault indicator with wireless communication for sensing cables. Prior Technology

[0002] A fault indicator is an electromagnetic induction device that reflects abnormal current flow. It is commonly used in high-voltage power distribution systems, such as power grids, high-voltage cables, and transformer boxes. Fault indicators can be used to detect abnormal current at any time, allowing monitoring personnel to become aware of abnormalities in the transmission of electrical energy more quickly.

[0003] Fault indicators can be classified according to the type of fault as short-circuit fault indicators, ground fault indicators, overload fault indicators, and open-circuit fault indicators. According to their working principle, they can be classified as flashing fault indicators, spring-loaded fault indicators, and cable fault indicators.

[0004] Fault indicators obtain values ​​by sensing voltage, current, etc., and then obtain data on abnormal states, such as short circuits or abnormal electrical transmission. When the fault indicator detects abnormal voltage or current, it will transmit an abnormal signal to an additionally installed buzzer or LED light, and notify the power supply abnormality by the beeping of the buzzer or the flashing of the LED light.

[0005] A current converter is a type of step-up transformer with a primary coil, a secondary coil, and a magnetic core. It converts a higher current value into a lower current value, thus enabling the detection of higher current values. It is used for current measurement or power grid monitoring. When using it, it is important to ensure that it is in a short-circuit state or connected to a meter when not in use. If the meter is not connected or it is short-circuited, the high voltage on the secondary side can easily lead to equipment damage or electric shock.

[0006] The flow meter can adjust its output value according to the control deviation. The change in the output value is proportional to the magnitude of the deviation. When used with different types of controllers, it can accurately control the output value.

[0007] Based on their sensing methods, current comparators are classified into four types: electromagnetic current comparators, electronic current comparators, Rogowski coil electronic current comparators, and Hall current comparators. Among them, electromagnetic current comparators are the more traditional type, as they contain an iron core, but this results in a larger size and weight, and magnetic saturation issues need to be considered. Although Hall current comparators contain an iron core, they are smaller than electromagnetic current comparators due to the sensor placement. Electronic current comparators do not contain an iron core, so they are smaller in both weight and size than electromagnetic current comparators. Furthermore, since they do not contain an iron core, they do not have the problem of magnetic saturation. Electronic current comparators use optical fiber to connect the primary and secondary coils, resulting in less electromagnetic interference. Rogowski coil electronic current comparators replace the coil part with a Rogowski coil (i.e., an air-core coil), which features real-time measurement, almost no phase error, and fast response speed.

[0008] The fault indicator originally did not include a communication system. Therefore, patrol personnel could only find out about the abnormality detected by the fault indicator by the sound of the buzzer or the light or flashing of the LED light when they were patrolling the site. Usually, when a power supply abnormality was encountered, the problem needed to be resolved as soon as possible. This required a large number of patrol personnel to search for the fault indicator that issued the warning, which not only consumed a lot of search time but also a lot of manpower.

[0009] Furthermore, although the fault indicator is equipped with a buzzer or LED light to notify the user of any abnormality, these two notification methods still have the potential to go unnoticed. For example, the LED light may not be visible due to obstruction by other objects, excessive sunlight, or reflections, or the buzzer may not be heard due to strong winds or rain. Therefore, a wireless communication module was later added to solve the problem that the abnormality may not be easily noticed by maintenance personnel.

[0010] Using a non-contact measurement method for fault indicators avoids human contact with high-voltage environments. Using an operating stick to place the fault indicator on the cable, rather than directly on it, further increases safety during installation. Traditionally, when installing a fault indicator on a cable, power must be shut off to prevent electric shock and ensure the safety of installers. Power is restored only after the fault indicator is fully installed. However, complex operation and inadequate installation can indeed affect measurement quality. At the same time, it is essential to ensure that the fault indicator, once installed on a high-voltage cable, remains stably in a specific position, without displacement due to slight external forces or detachment from the high-voltage cable, thus maintaining the quality of cable measurements.

[0011] To address the aforementioned problems, this invention provides a fault indicator comprising a base, an anti-slip pad, a clamping device, and a sensing and processing circuit. When a cable is pulled, one of the clamping clips of the clamping device is forced upwards, causing the cable to slide along the clip into a receiving chamber of the base. The clip and the anti-slip pad clamp the cable. The sensing and processing circuit senses the cable, obtaining a voltage sensing signal and a current sensing signal, and generates a sensing signal. This fault indicator allows personnel to install it away from high-voltage electricity, and simultaneously achieves remote monitoring through non-contact detection combined with wireless communication. Summary of the Invention

[0012] One objective of this invention is to provide a non-contact measurement fault indicator with wireless communication, which allows personnel to avoid high voltage when installing the non-contact measurement fault indicator on cables, increasing the safety of the installation. Furthermore, the non-contact sensing and processing circuit senses the voltage and current of the cable and transmits the sensing results to a remote host via wireless communication to achieve remote monitoring of whether the power transmission of the cable is abnormal.

Implementation

[0024] To enable your review committee to have a better understanding of the features and effects of this invention, the following examples and accompanying descriptions are provided:

[0025] It is known that a power outage is required to install non-contact fault indicators in order to ensure the safety of personnel during installation. However, a power outage that lasts too long can cause inconvenience to users. Furthermore, once installed, the non-contact fault indicator must be clamped in place to prevent it from moving or falling off the cable due to even minor external forces.

[0026] Accordingly, the present invention proposes a non-contact measurement fault indicator. By setting an anti-slip pad, the non-contact measurement fault indicator is more securely installed on the cable. At the same time, the non-contact measurement fault indicator can be safely installed on the cable by using an operating rod, eliminating the need for personnel to install it in a high-voltage environment and increasing safety during installation.

[0027] The invention will be described in detail below by way of the drawings illustrating various embodiments thereof. However, the concept of the invention may be embodied in many different forms and should not be construed as being limited to the exemplary embodiments set forth herein.

[0028] First, please refer to Figure 1, which is a perspective view of one embodiment of the present invention. As shown in the figure, the present invention provides a non-contact measurement fault indicator 1 with wireless communication, which is used to detect a cable 2 and confirm whether the power transmission of the cable 2 is abnormal.

A receiving portion 106 is formed between the base 10, the first extension 1022 and the second extension 1042. The anti-slip pad 12 is disposed between the base 10 and the receiving portion 106.

[0030] Continuing from the above, the accommodating part 106 has a U-shaped structure.

[0031] Continuing from the above, referring together with Figures 2A and 2B, which are a first schematic diagram of the opening of the clamping fastener abutting against the second extension portion according to an embodiment of the present invention, and a second schematic diagram of the opening of the clamping fastener abutting against the second extension portion according to an embodiment of the present invention, the clamping fastener 14 is disposed on the first extension portion 1022, the clamping fastener 14 includes an elastic connecting portion 142 and a clamping piece 144, the elastic connecting portion 142 is fixed to the first extension portion 1022, and one end of the clamping piece 144 extends downward to provide a first pivot portion 1442 and a second pivot portion 1442. The first pivot portion 1442 and the second pivot portion 1444 are connected to the elastic connecting portion 142. The other end of the clip 144 extends outward from the second extension portion 1042 to form a clip extension portion 1446. A first bending portion 1441 is provided between the clip 144 and the clip extension portion. The clip 144 is provided with an opening 1448. The base 10 passes through the second extension portion 1042 through the opening 1448 so that one end of the clip 144 through the opening 1448 abuts against the second extension portion 1042.

[0032] Continuing from the above, one end of the clip 144 is further provided with a second bending portion 1443, and the bending angles of the first bending portion 1441 and the second bending portion 1443 are different.

[0033] Continuing from the above, an elastic element 1445 is provided on one side of the clamping piece 144. The elastic element 1445 includes a spring or other elastic structure to increase the clamping force of the clamping piece 144.

[0034] Continuing from the above, the elastic connection portion 142 includes a torsion spring 1422 and a pivot member 1424. One end of the torsion spring 1422 extends between the first extension portion 1022 and the first pivot portion 1442 and abuts against the clip 144. The other end of the torsion spring 1422 extends between the first extension portion 1022 and the second pivot portion 1444 and abuts against the clip 144. One end of the torsion spring 1422 is connected to the other end of the torsion spring 1422 to form a U-shaped structure and abuts against the first extension portion 1022. The pivot member 1424 is sequentially inserted through the first pivot portion 1442, one end of the torsion spring 1422, the first extension portion 1022, the other end of the torsion spring 1422, and the second pivot portion 1444.

[0035] Continuing from the above, and referring to Figure 3 of this document, which is a schematic diagram of a detection cable according to an embodiment of the present invention, the sensing processing circuit 16 is disposed below the base 10. The sensing processing circuit 16 is electrically connected to a voltage sensing circuit 161 and a current sensing circuit 162. The voltage sensing circuit 161 is provided with a sensing electrode 1612, and the current sensing circuit 162 is provided with an induction coil 1622. The current sensing circuit 162 is a current converter.

[0036] Continuing from the above, the sensing processing circuit 16 further includes a conversion circuit 163, an analog-to-digital converter 164, a microprocessor 165, a wireless communication circuit 166, a battery 167, and a backup line 168. The conversion circuit 163 is electrically connected to the voltage sensing circuit 161 and the current sensing circuit 162. The analog-to-digital converter 164 is electrically connected to the conversion circuit 163. The microprocessor 165 is electrically connected to the analog-to-digital converter 164. The wireless communication circuit 166... The microprocessor 165 is electrically connected, and the battery 167 is electrically connected to and supplies power to the conversion circuit 163, the analog-to-digital converter 164, the microprocessor 165, and the wireless communication circuit 166. The backup line 168 is used for the electrical connection between the wireless communication circuit 166 and the microprocessor 165. When the transmission of messages between the wireless communication circuit 166 and the microprocessor 165 is abnormal, the wireless communication circuit 166 transmits messages to the microprocessor 165 through the backup line 168.

[0037] Continuing from the above, the non-contact measurement fault indicator 1 further includes a light-emitting unit 18 and a lampshade 19. The light-emitting unit 18 is disposed below the base 10 and electrically connected to the sensing and processing circuit 16. The lampshade 19 is disposed below the base 10 and covers the light-emitting unit 18. The lampshade 19 extends with a third extension 192, and an opening 194 is formed between the third extension 192 and the lampshade 19. The non-contact measurement fault indicator 1 is placed on the cable 2 by clamping the opening 194 with an operating rod.

[0038] Continuing from the above, the user uses an operating rod to clamp the opening 194 and moves the non-contact measurement fault indicator 1 to one side of the cable 2. Using the cable 2, the user pulls the clip 144, causing it to open upwards. The cable 2 slides along the clip 144 into the receiving portion 106. When the cable 2 is in the receiving portion 106, the elastic connection 142, through the torsion spring 1422 and the pivot member 1424, abuts against the first extension 1022 and the clip 144. The first elastic force of the torsion spring 1422 is applied to the clip 144, causing it to exert downward force on the cable 2. The elastic member 1445 located on one side of the clip 144 provides a second elastic force... The cable 2, and the anti-slip pad 12 apply friction to the cable 2. The clamp 144 and the anti-slip pad 12 clamp the cable 2, so that the non-contact measurement fault indicator 1 holds the cable 2. Due to sufficient friction, the non-contact measurement fault indicator 1 is fixed on the cable 2 and will not move at will. After the non-contact measurement fault indicator 1 is set, the user removes the operating stick. The non-contact measurement fault indicator 1 senses the cable 2 through the voltage sensing circuit 161 and the current sensing circuit 162. The sensing processing circuit 16 generates a sensing signal 1652 based on the signals obtained by the voltage sensing circuit 161 and the current sensing circuit 162.

[0039] Continuing from the above, the voltage sensing circuit 161 uses the sensing electrode 1612 to sense the cable 2, and the current sensing circuit 162 uses the induction coil 1622 to sense the cable 2. The sensing electrode 1612 and the induction coil 1622 are not in direct contact with the cable 2. When there is a potential difference between the cable 2 and the sensing electrode 1612, capacitive coupling will occur between the cable 2 and the sensing electrode 1612, thereby generating a voltage sensing signal 16122. The current sensing circuit 162 uses the Hall effect of the induction coil 1622 to sense the current flowing through the cable 2 and generates a current sensing signal 16222. The current sensing signal 16222 is the Hall voltage caused by the magnetic field generated when the current passes through.

[0040] Continuing from the above, the conversion circuit 163 receives the voltage sensing signal 16122 and generates a first analog signal 1632. The conversion circuit 163 also receives the current sensing signal 16222 and generates a second analog signal 1634. The analog-to-digital converter 164 receives the first analog signal 1632 and the second analog signal 1634. The analog-to-digital converter 164 generates a first DC voltage signal 1642 based on the first analog signal 1632 and a second DC voltage signal 1644 based on the second analog signal 1634. The microprocessor 165 receives the first DC voltage signal 1642 and the second DC voltage signal 1644. The DC voltage signal 1644 is used to determine whether the first DC voltage signal 1642 and the second DC voltage signal 1644 are abnormal based on a preset threshold value, and the sensing signal 1652 is generated. The sensing signal 1652 is transmitted to the light-emitting unit 18 and a remote host 3 through the wireless communication circuit 166. The light-emitting unit 18 generates a light according to the sensing signal 1652. The light-emitting unit 18 notifies people around whether the cable 2 is in an abnormal state by the color of the light. The remote host 3 receives the sensing signal 1652, and the monitor can monitor whether the cable 2 is in an abnormal state through the remote host 3.

[0041] Continuing from the above, one of the communication protocols supported by the wireless communication circuit 166 is LTE-M, WI-FI, BT, LoRa, Wi-SUN, or NB-IoT.

[0042] Continuing from the above, the wireless communication circuit 166 generates a corresponding packet based on the sensing signal 1652. The packet contains an access location or a product number. The monitor uses the access location or the product number to locate the non-contact measurement fault indicator 1 that issued the abnormal message and to understand the location of the cable 2 that is transmitting abnormal power.

[0043] The embodiments described above provide a non-contact measurement fault indicator with wireless communication. The friction generated by the anti-slip pad and the elastic force provided by the torsion spring and elastic element are applied to the clamp, clamping the cable and fixing the non-contact measurement fault indicator at a specific position on the cable. Furthermore, the third extension and opening provided by the lampshade extension allow the user to install the non-contact measurement fault indicator onto the cable using an operating rod, without needing to be too close to the cable, increasing user safety during installation. The voltage and current sensing circuits within the non-contact measurement fault indicator measure values, which are then processed by the sensing processing circuit and transmitted to a remote host to achieve remote monitoring.

[0044] Therefore, this invention is indeed novel, inventive, and industrially applicable, and undoubtedly meets the requirements for patent application under the Patent Law of our country. Thus, we hereby file an invention patent application in accordance with the law, and earnestly pray that the Bureau will grant the patent as soon as possible.
