[0002] Since the alternating electromagnetic field of DC transmission lines is extremely weak, the electromagnetic induction coupling method has a poor effect in extracting energy. It is known that the corona loss of DC transmission lines accounts for a considerable proportion of DC transmission losses.

Although the collection current can be increased to a certain extent through the design of the collector's appearance and the selection of the installation location, the technical difficulty of this power collection method is still to achieve efficient conversion of high voltage and weak current. For example, if the collection current is as low as microamperes, which is almost the leakage current level of many switching devices and triggering devices, then all conventional converters will definitely not work.

[0046] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the drawings of the specification. Obviously, the described embodiments are part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary persons in the art without creative work should fall within the scope of protection of the present invention.

[0047] Example 1

[0048] Reference Figure 1-Figure 6 , which is the first embodiment of the present invention, and provides a high-voltage micro-current conversion method and system, including:

[0049] There are some problems in the existing related technologies. For example, traditional power conversion equipment often cannot effectively handle high-voltage microcurrents, resulting in low energy conversion efficiency. In addition, due to the large corona loss of DC transmission lines, how to efficiently collect power from transmission lines and convert them into usable power forms has always been a challenge in the field of power automation. Existing technical solutions often cannot meet the stability and continuity requirements of special equipment for power, especially in harsh environmental conditions, such as thunderstorms, the stability and safety of the equipment are even more difficult to guarantee.

[0050] This application provides a method that can effectively solve the above-mentioned problems. Next, we will combine multiple embodiments to explain in detail how to implement the high-voltage micro-current conversion method;

[0051] Figure 1 A method flow chart of a high-voltage micro-current conversion method and system is shown, including:

[0052] S101, collecting space charges of a target transmission line to perform first electric energy storage;

[0053] In an optional embodiment, in order to realize high-voltage micro-current conversion, space charges of the target transmission line are collected, and current is formed through the space charges of the target transmission line to perform the first electric energy storage. There are many ways to collect the space charges of the target transmission line;

[0054] In an optional embodiment, this can be done by a corona collector. The corona collector is usually installed at an appropriate position of the transmission line to capture the space ions generated by the corona discharge. These ions will move toward the collector under the action of the electric field and accumulate on the electrodes of the collector to form an electric current. Since the current generated by corona discharge is usually very small, a highly sensitive corona collector is required to ensure that these weak currents can be effectively collected.

[0055] In another optional embodiment, the corona collector can also be combined with other components for collection, such as lightning protection components, to improve the overall performance and safety of the system. The lightning protection components can prevent current overload caused by lightning activity, thereby protecting the entire high-voltage micro-current conversion system from damage.

[0056] In another optional embodiment, the corona collector can also be combined with other elements for collection, such as a temperature compensation unit, to adapt to the changes in corona discharge characteristics under different ambient temperatures. The temperature compensation unit can automatically adjust the working parameters of the corona collector according to the changes in ambient temperature to ensure that space charges can be efficiently collected under different temperature conditions. This design helps to improve the stability and reliability of power collection, especially in environments with large temperature fluctuations.

[0057] In the embodiment of the present application, the space charge of the target transmission line is collected by a corona collector in combination with a lightning protection element.

[0058] In another optional embodiment, the structural design of the corona collector can be optimized to improve its efficiency in capturing space charges. For example, electrodes with a larger surface area can be used, or special materials can be used to enhance the adsorption capacity of the electrodes for charges. In addition, the installation angle and position of the corona collector can be adjusted to adapt to different environmental conditions, thereby further improving the efficiency of electric energy collection.

[0059] In another optional embodiment, other types of charge collectors can also be used. The reason why the lightning arrester is used as the charge collector is that, firstly, its multi-metal tip structure forms a high electric field gradient to form corona or absorbs space charge physical effects at the same time, both of which can form current in the sampling loop; secondly, it is a common mature product, which can save costs and production time.

[0060] In the present application example, Figure 2 , 3 The lightning arrester shown acts as a component for collecting space charge of the target transmission line.

[0061] In the embodiment of the present application, by designing Figure 2 , 3 The corona collector A shown in FIG. 1 is used for space charge collection, where Figure 4 As shown, G1 and G2 are lightning protection elements composed of a gas discharge tube and a current limiting inductor L. The corona charge collector A collects the space charge of the high-voltage DC transmission line, and the resulting current charges the capacitor C1 through the inductor L1.

[0062] In the embodiment of the present application, the discharge voltage of the gas discharge tubes G1 and G2 is 230V10kA. L1 is 470uH to limit the discharge current of G2.

[0063] For example, Figure 3 As shown, the structure of the practical charge collector A (i.e., lightning eliminator) of the present application includes an antenna, a waterproof cover, a waterproof cover 2, and an insulator, which is used for charge collection. The lightning eliminator needs to be insulated and equipped with an installation bracket to be installed at an appropriate position on the transmission tower, so that there is a sufficient safety distance and the charge can be effectively collected.

[0064] In an optional embodiment, the first electrical energy storage can be implemented using a variety of components, such as capacitors. The capacitor plays a key role in the charge collector, which can store the charges generated by the corona discharge and release these charges when needed. In order to improve the storage efficiency, the capacitor usually needs to have the characteristics of high withstand voltage and large capacity. In this embodiment, the capacitor is designed to withstand high voltage input and has sufficient capacitance to store enough electrical energy to meet the subsequent power supply requirements.

[0065] In another optional embodiment, the first electrical energy storage may further include a voltage regulator. The function of the voltage regulator is to ensure that the voltage across the capacitor remains within a safe and effective range. Since the voltage generated by corona discharge may be unstable, the voltage regulator can prevent excessive voltage from damaging the capacitor or other circuit components, while ensuring the stability of the output voltage and providing a stable input for subsequent electrical energy conversion.

[0066] In another optional embodiment, the capacitor for storing the first electric energy and the voltage regulator can be integrated into a module, which is designed to be directly installed on a transmission tower and connected to the corona collector A. Such a design not only simplifies the installation and maintenance of the system, but also improves the reliability and adaptability of the system due to the modular design.

[0067] In another optional embodiment, the first energy storage module may further include a monitoring unit for real-time monitoring of the voltage and current status of the capacitor. The monitoring unit may provide fault diagnosis and early warning functions to ensure that the system can take timely measures to prevent equipment damage or performance degradation when an abnormality occurs. In addition, the data of the monitoring unit may also be used for subsequent system optimization and maintenance decisions.

[0068] In the embodiment of the present application, in order to simplify the structure, a capacitor C1 is selected to store the first electric energy. Figure 4 , 5 As shown in the figure, the corona charge collector A collects the space charge of the high-voltage DC transmission line, and the resulting current charges the capacitor C1 through the inductor L1.

[0069] It should be noted that relevant technicians can design other electrical components with similar functions or modules or units with other integrated functions according to actual needs, but these operations should all be within the scope of protection of this application.

[0070] It should also be noted that collecting the spatial charge of the target transmission line and performing the first electric energy storage can ensure that there is sufficient electric energy reserve to meet the needs of subsequent steps during the high-voltage micro-current conversion process. After the first electric energy storage is completed, the system will determine whether the stored electric energy meets the first conduction requirement, that is, whether the conditions for the second electric energy storage are met. If the conditions are met, the system will enter the second electric energy storage stage and continue to collect and store electric energy until the electric energy value required for the first working requirement of the target load is reached. This process ensures the continuous supply of electric energy and meets the requirements of special equipment for electric energy stability and continuity. Through such a design, the present invention not only improves the efficiency of electric energy collection, but also optimizes the storage and output process of electric energy, providing a stable and reliable power supply solution for special equipment.

[0071] S102, determining whether the value of the first electric energy storage meets the first conduction requirement;

[0072] In an optional embodiment, the first conduction requirement is designed for the amount of first electrical energy storage. If the electrical energy formed by the collected space charge of the target transmission line does not meet the first conduction requirement, conduction is not required. If the first conduction requirement is met, conduction can be performed for the second electrical energy storage, thereby achieving high-voltage micro-current conversion.

[0073] In an optional embodiment, the first conduction requirement can be designed by configuring a threshold value. For example, when the value of the first electric energy storage reaches a preset threshold value, the system will automatically trigger the second electric energy storage process.

[0074] In an optional embodiment, the first conduction requirement may be designed by configuring different components, for example, by setting different capacitance values ​​or resistance values ​​to adjust the threshold of the first conduction requirement.

[0075] In an optional embodiment, a variable resistor or a programmable logic controller (PLC) may be used to dynamically adjust the threshold value to adapt to different working environments and load requirements.

[0076] In an optional embodiment, the judgment of the first conduction requirement can also be combined with the time factor. For example, only after the first electrical energy storage reaches a certain amount and lasts for a certain period of time, the system will consider that the conduction condition is met, thereby avoiding misoperation caused by instantaneous electrical energy fluctuations.

[0077] It should be noted that, because the design of this application takes into account the realization of high-voltage micro-current conversion as efficiently as possible, the first conduction requirement is designed to be relatively sensitive, and in order to achieve this relatively sensitive function, electrical components with lower triggering requirements must be used;

[0078] In the embodiment of the present application, a micro-trigger thyristor T1 is used as a trigger element, and the neon tubes N1, N2 and the micro-trigger thyristor T1 form a first conduction requirement, such as Figure 4 , 5 As shown in the figure, when the voltage of capacitor C1 rises to the discharge voltage of neon tubes N1 and N2, the micro-trigger thyristor T1 is triggered to conduct, and the DC charge in capacitor C1 charges capacitor C2 through micro-trigger thyristor T1 and inductor L2. As capacitor C1 discharges, the voltage across it continues to drop until micro-trigger thyristor T1 is turned off, and capacitor C1 starts the next charge and discharge process. After micro-trigger thyristor T1 is turned off, the current flowing through inductor L2 continues to flow through capacitor C2 and diode D1, converting the magnetic energy of inductor L2 into electrical energy and sending it to capacitor C2 for storage.

[0079] In an optional embodiment, because the starting voltage of an ordinary neon tube is about 86.7V. Under the condition of constant current, the more neon tubes are used, the higher the voltage at point b, the higher the voltage at point c, and the greater the charging energy obtained by C1. The converter can theoretically withstand an input voltage of 400V, but an increase in the voltage at point b also means an increase in the voltage at point a, which increases the voltage of the insulator to the ground. The increase in voltage will also cause the leakage current of the supporting insulator. If the surface of the insulator is contaminated, the leakage current will increase further. This will cause most of the current collected by antenna A to be shunted away through the insulator, and once the current sent to capacitor C1 is less than its leakage current, C1 cannot be charged. If only one is used, due to the low charging voltage, C1 will not be able to provide energy to the back end to support the load operation requirements.

[0080] In the embodiment of the present application, the above-mentioned situations are comprehensively considered and two neon tubes are selected with a trigger voltage of 176V, which can not only reduce the shunt current of the insulator, but also ensure the output power requirement of C1 for the back-end equipment.

[0081] In an optional embodiment, relevant technical personnel can make design selections based on actual needs, and this application does not limit this.

[0082] It should be noted that judging whether the value of the first electrical energy storage meets the first conduction requirement ensures that the system will enter the next conversion stage only when the electrical energy reserve reaches a certain level, thereby avoiding low conversion efficiency or equipment damage caused by insufficient electrical energy. This design makes the high-voltage micro-current conversion system more stable and reliable, especially in harsh environmental conditions, such as lightning weather, to ensure the stable operation and safety of the equipment. By precisely controlling the first conduction requirement, the system can effectively manage the collection and storage process of electrical energy to ensure that continuous and stable electrical energy output can be provided when needed. In addition, by using appropriate trigger elements and threshold settings, the system can flexibly adapt to different working environments and load requirements, further improving the efficiency and applicability of high-voltage micro-current conversion.

[0083] S103, if the first conduction requirement is met, performing second electric energy storage, and determining whether the value of the second electric energy storage meets the first working requirement of the target load;

[0084] In the embodiment of the present application, if the first conduction requirement is met, performing the second electrical energy storage includes:

[0085] If the first conduction requirement is met, the second electrical energy storage is performed using the value of the first electrical energy storage;

[0086] A first storage threshold is preset, and if the value of the first electric energy storage is greater than the first storage threshold, the value of the first electric energy storage continues to perform the second electric energy storage;

[0087] If the value of the first electric energy storage is not greater than the first storage threshold, the value of the first electric energy storage stops performing the second electric energy storage.

[0088] In an optional embodiment, the first storage threshold may be designed according to the first conduction requirement and may be implemented using different electrical components.

[0089] In the embodiment of the present application, the first storage threshold is designed by the neon tubes N1, N2 and the micro-trigger thyristor T1, and the value of the first storage threshold is realized by the neon tubes N1, N2 and the micro-trigger thyristor T1.

[0090] In the embodiment of the present application, as the capacitor C1 discharges, the voltage across it continues to drop until the micro-trigger thyristor T1 is turned off, and the capacitor C1 starts the next charge and discharge process. After the micro-trigger thyristor T1 is turned off, the current flowing through the inductor L2 is continued through the capacitor C2 and the diode D1, and the magnetic energy of the inductor L2 is converted into electrical energy and sent to the capacitor C2 for storage. The voltage of the capacitor C2 is charged to the turn-on value of the hysteresis circuit, and the low-dropout linear regulator LDO is turned on to provide output for the load. As the load is consumed, when the voltage of C2 drops to the turn-off value of the hysteresis circuit, the LDO is turned off, and C2 starts the next charge and discharge process.

[0091] In the embodiment of the present application, the first working requirement of the target load includes: the value of the second electric energy storage is configured as the electric energy required for the target load to work for several times.

[0092] It should be noted that relevant technicians can adjust the second electric energy storage capacity according to actual needs;

[0093] In the embodiment of the present application, in order to ensure the simplicity and accuracy of the entire circuit, the value of the second electric energy storage is configured as the electric energy required for a single working time of the target load.

[0094] In the embodiment of the present application, after waiting for the target load to be powered several times, the value of the remaining second electric energy storage is determined;

[0095] If the remaining second electric energy storage value is less than the electric energy required for a single working time of the target load, the first consumption operation is performed.

[0096] In the embodiment of the present application, the first consumption operation includes:

[0097] The first consumption operation is used to consume the excess electric energy stored in the second electric energy;

[0098] After waiting for the first consumption operation to be completed, the second electric energy storage is performed again, and it is determined whether the value of the second electric energy storage meets the first working requirement of the target load.

[0099] In the embodiment of the present application, the first consumption operation is realized by D1, the capacity of capacitor C2 is required to meet the capacity of the electric energy required by the load for one working time in one discharge, and the current of corona collector A is required to meet the requirement of filling C2 during the load rest period, so that the power supply and load of the whole system can achieve supply and demand balance. If the power supply has surplus energy, it is consumed by D1, so that the voltage of C2 is limited to the voltage regulation value of D1.

[0100] It should be noted that if the first conduction requirement is met, the second electric energy storage is performed, and judging whether the value of the second electric energy storage meets the first working requirement of the target load can ensure that the system will not be interrupted due to insufficient electric energy during the operation of the target load. In addition, in this way, the system can effectively manage the storage and consumption of electric energy, thereby extending the service life of the equipment and improving energy efficiency. After the first conduction requirement is met, the system will continue to monitor the electric energy level of the second electric energy storage to ensure that the electric energy storage reaches or exceeds the required level before the load works again, thereby ensuring the stable operation of the entire system.

[0101] S104: If the first working requirement of the target load is met, a first power supply output is performed to complete the high-voltage micro-current conversion.

[0102] In the embodiment of the present application, when the voltage of capacitor C2 is charged to the hysteresis circuit turn-on value, the low dropout linear regulator LDO is turned on to provide output for the load. As the load consumes, when the voltage of C2 decreases to the hysteresis circuit turn-off value, the LDO is turned off, and C2 starts the next charging and discharging process.

[0103] In summary, the present invention proposes a high-voltage micro-current conversion method, which collects the spatial charge of the target transmission line and performs the first electric energy storage; determines whether the value of the first electric energy storage meets the first conduction requirement; if the first conduction requirement is met, the second electric energy storage is performed, and it is determined whether the value of the second electric energy storage meets the first working requirement of the target load; if the first working requirement of the target load is met, the first power supply output is performed to complete the high-voltage micro-current conversion. It can effectively convert high-voltage micro-current into usable electric energy, solving the problem that it is difficult to efficiently convert high-voltage weak current in traditional technologies.

[0118] It should be noted that the loads carried by the micro-power source are all intermittently working. The rest period refers to the period when the load is out of operation, during which C2 is in the process of charging and storing energy; during the load working period, C2 is in the process of discharging and supplying power to the load. Therefore, intermittent operation is achieved by setting the first load rest threshold.

The communication interface of the computer device is used to communicate with an external terminal in a wired or wireless manner, and the wireless manner can be achieved through WIFI, an operator network, NFC (near field communication) or other technologies. When the computer program is executed by the processor, a high-voltage micro-current conversion method is implemented. The display screen of the computer device can be a liquid crystal display screen or an electronic ink display screen, and the input device of the computer device can be a touch layer covered on the display screen, or a button, trackball or touchpad set on the computer device housing, or an external keyboard, touchpad or mouse, etc.

[0127] Example 3

[0128] In a preferred embodiment, a circuit structure based on the above-mentioned embodiment method and system is designed, such as Figure 4 As shown;

[0129] Among them, the corona charge collector A collects the space charge of the high-voltage DC transmission line, and the resulting current charges the capacitor C1 through the inductor L1. When the voltage of the capacitor C1 rises to the discharge voltage of the neon tubes N1 and N2, the micro-trigger thyristor T1 is triggered to conduct, and the DC charge in the capacitor C1 charges the capacitor C2 through the micro-trigger thyristor T1 and the inductor L2.

[0130] As capacitor C1 discharges, the voltage across its two ends continues to drop until the micro-trigger thyristor T1 is turned off, and capacitor C1 begins the next charge and discharge process. After the micro-trigger thyristor T1 is turned off, the current flowing through inductor L2 continues through capacitor C2 and diode D1, converting the magnetic energy of inductor L2 into electrical energy and sending it to capacitor C2 for storage. When the voltage of capacitor C2 is charged to the turn-on value of the hysteresis circuit, the low-dropout linear regulator LDO is turned on to provide output for the load. As the load consumes, when the voltage of C2 drops to the turn-off value of the hysteresis circuit, the LDO is turned off, and C2 begins the next charge and discharge process.

[0131] The capacity of capacitor C2 is required to meet the capacity of the electrical energy required by the load for one working time in one discharge, and the current of corona collector A is required to be sufficient to fully charge C2 during the load rest period, so that the power supply and load of the entire system can achieve supply and demand balance.

[0132] If the power supply has excess energy, it will be consumed by D1, limiting the voltage of C2 to the voltage regulation value of D1. The gas discharge tubes G1, G2 and current limiting inductor L1 in the circuit constitute lightning protection.

[0133] C1 charges -> C1 voltage rises to set value 1 -> LDO turns on power supply -> C1 voltage drops to set value 2 -> LDO turns off to recharge C1. The specific design is that when the input voltage (Vin) reaches 8V, the hysteresis control circuit outputs a high level, so that the LDO device is turned on to supply power to the load. At this time, the Vin voltage gradually decreases with the power supply. When the input voltage (Vin) is lower than 3.5V, the hysteresis control circuit outputs a low level, turns off the LDO power supply to the load, and charges C1.

[0134] In the embodiment of the present application, G1 and G2 discharge tubes are 230V10kA, L1 inductor is 470uH, C1 ceramic capacitor is 0.022uF / 1kV, the starting voltage of N1 and N2 neon tubes is about 86.7V, T1 micro-trigger thyristor MCR100, the on-state holding current is 5mA, D1 diode is 1N4007, L2 inductor is 100mH, C2 electrolytic capacitor is 470uF / 16V, and LDO linear voltage regulator is 3.3V / 400mA.

[0135] In an optional embodiment, the thyristor conduction is the neon tube string ignition voltage value, here when the C1 voltage is charged to 176V; when the C1 discharge current drops below the thyristor minimum holding current, the thyristor is turned off. The holding current of MCR100 is 5mA, that is, when the C1 discharge current is lower than 5mA, the thyristor is turned off.

[0136] In an optional embodiment, the selection of the on / off threshold of the voltage monitor is determined according to the load power consumption. For example, if the load consumes a lot of power each time and the intermittent period is long, the on voltage value is required to be set higher to ensure that the C2 energy storage can meet the load's one-time work needs; otherwise, it is set lower to meet the intermittent period power supply with a smaller load.

[0137] In an optional embodiment, the loads carried by the micro-power source are all intermittently working. The rest period refers to the load shutdown period, during which C2 is in the process of charging and storing energy; during the load working period, C2 is in the process of discharging and supplies power to the load.

[0138] like Figure 5 As shown, a voltage regulator diode D2 is added to the specific real-time circuit, the voltage regulation value is 8.2V, the LDO uses HM1235B33, the voltage regulation voltage is 3.3V, and the hysteresis control chip uses CS7036.

[0139] The working process is as follows: the space charge is received through antenna A to form current I0, which charges capacitor C1. When the voltage at point b reaches the discharge voltage of N1 and N2, 176V, N1 and N2 are turned on, the micro-trigger thyristor T1 is turned on, and the voltage of C1 is 176V, which supplies power to the BUCK circuit composed of D1, L2, and C2, and stabilizes the voltage to about 8V. D2 is used to ensure that the maximum voltage of the output LDO chip (HM1235B33) does not exceed 8.2V. At this time, the hysteresis control chip CS7036 detects that the Vin voltage reaches 8V, and turns on the enable of the LDO chip HM1235B33, so that it can output power to the load at a voltage of 3.3V. When the load consumes the energy of C1 and the voltage of Vin drops to 3.5V, the hysteresis control chip CS7036 turns off the output of LDO, so that C1 is in a charging state. The whole circuit repeats this way, intermittently supplying power to the load.

[0140] In summary, the present application uses a small-capacity capacitor to charge the weak charge current to a higher voltage for DC-DC conversion, so that the weak charge current with constant current source characteristics can be used as efficiently as possible. The extremely weak leakage current characteristics of the neon tube are used in conjunction with a micro-trigger thyristor to form a switching element of a Buck topology DC-DC converter to complete the DC-DC conversion of the weak current source. A voltage monitoring chip is used to control the on and off of the low-dropout regulator, so that the larger capacity energy storage capacitor is intermittently charged and discharged to maintain the balance of power supply and demand.
