Description

Technical Field

[0002] Cables above 35kV mainly use single-core cables with metal sheaths. Because the metal sheath of the single-core cable is hinged with the magnetic lines of force generated by the AC current in the core wire, a high induced voltage appears at both ends, so appropriate grounding measures must be taken to keep the induced voltage within the safe voltage range. At the same time, when the cable sheath insulation is damaged, the metal sheath grounding current will be abnormal, affecting the current carrying capacity of the cable, and in severe cases, even causing the cable to heat up severely and burn.

[0003] In order to better monitor the working condition of cables, a large number of online monitoring devices for cable sheath circulating current are currently installed on cable transmission lines to monitor the grounding current of cable sheaths. However, due to the limitations of the cable monitoring environment and the design problems of early devices, most of the existing online monitoring devices for cable sheath circulating current only support current transformer (CT) coupling power extraction, which has a single power extraction method and cannot be compatible with or expand the access of other energy extraction methods; when the cable line is in a low-load condition, the monitoring equipment will be dormant and offline due to the inability to obtain sufficient energy through coupling power extraction. Other cable-type online monitoring devices also face the problems of difficulty in obtaining power and low-load offline. For example, traditional solar power extraction has the problem of being unable to obtain energy at night; when the mains power extraction or external DC current power supply is designed and installed during the construction, it may not be in use, and it is also impossible to obtain sufficient energy.

[0032] Embodiment 1

[0033] Figure 1 and Figure 2 The schematic diagram of the structure of the energy taking device of the cable online monitoring device according to the embodiment of the present disclosure is shown as follows: Figure 1 and Figure 2As shown, an energy acquisition device for a cable online monitoring device provided by an embodiment of the present disclosure includes a power supply control conversion circuit 1 and a plurality of energy acquisition modules 2, wherein the power supply control conversion circuit 1 is respectively connected to the plurality of energy acquisition modules 2, and the power supply control conversion circuit 1 can select at least one energy acquisition module 2 from the plurality of energy acquisition modules 2 according to the installation environment of the cable online monitoring device to power the cable online monitoring device.

[0034] Among them, each energy acquisition module 2 represents an energy acquisition method. The cable online monitoring device can select two or more energy acquisition methods to work simultaneously according to the installation environment around it, which makes up for the problem of insufficient energy supply in a single power acquisition method to a certain extent, improves the power acquisition reliability of the power acquisition device, and improves the online rate of the cable online monitoring device. In this embodiment, different energy acquisition modules 2 are independent of the power control conversion circuit 1 and do not interfere with each other; in the line connected between each energy acquisition module 2 and the power control conversion circuit 1, when any one or more of the lines fail, it does not affect the power supply of other normal power acquisition paths, further ensuring the power acquisition reliability of the power acquisition device and the online rate of the cable online monitoring device.

[0035] In addition, the above-mentioned power extraction device can be used to transform the power extraction method of existing equipment with a single power extraction method, thereby improving the online rate of existing equipment. The transformation method is flexible and convenient. For example, the existing current transformer coupled power extraction equipment can be transformed to obtain a power extraction device including multiple energy extraction modules 2. The power extraction device provided in this embodiment can ensure the reliable operation of the cable online monitoring equipment, monitor the cable through the monitoring equipment, and promptly detect the situation where the cable load exceeds the standard, and take corresponding measures to adjust it, thereby solving the impact problem of the power extraction equipment under high cable load conditions.

[0036] In some embodiments, the energy acquisition module 2 includes a solar energy acquisition module 21 , a cable coupling energy acquisition module 22 and a mains power energy acquisition module 23 .

[0037] In this embodiment, the commonly used power supply methods such as current transformer (CT) coupling power supply, mains power supply, and solar power supply are taken into consideration, and the corresponding energy supply module 2 can be flexibly selected according to the installation environment of the online monitoring equipment. For example, in order to meet the monitoring requirements of the cable sheath circulating current online monitoring device, current transformer coupling power supply can be preferentially selected. At the same time, the load condition of the cable line is monitored in real time through the online monitoring device. When the cable line is in a low-load condition, if the installation environment of the cable online monitoring equipment is during the day, while the current transformer coupling power supply is being performed, the solar energy supply module 21 is selected for power supply to avoid the cable online monitoring equipment being offline due to low load; if the installation environment of the cable online monitoring equipment is at night, while the current transformer coupling power supply is being performed, the mains power supply is selected to avoid the cable online monitoring equipment being offline due to low load. The mains power supply module 23 is, for example, AC 220V (50Hz).

[0038] When electricity is obtained through the solar energy acquisition module 21, the solar energy acquisition module 21 can use a solar illumination simulator to test and obtain the VI curve of the solar panel (for example, the model designed for use) at different output voltages, which is recorded as the matrix UI. The operating matrix P (power) of the solar panel is calculated based on the UI matrix, and the weighted sum of the powers under different illumination conditions at the same output voltage is calculated based on the matrix P (the weighting coefficient is selected as 1) to obtain the approximate matrix PM. PM is used to approximately simulate and express the sunshine power output ratio of the solar panel under different control output voltages. Then, the maximum output power ratio in the PM matrix is ​​selected, and the voltage value of the power ratio is taken as the optimal output voltage point of the solar panel.

[0039] When power is taken through the cable-coupled energy-taking module 22, the cable-coupled energy-taking module 22 uses a relay protection instrument to simulate the test to obtain the VI curve of the power-taking type current transformer (designed model) at different output voltages, which is recorded as the matrix UI. And the working condition matrix P (power) of the power-taking type current transformer is calculated based on the UI matrix. By monitoring the output current I after rectification of the current transformer, the switching duty cycle of the rectification process at the front end is adjusted to limit its power input range. During design, the UI matrix is ​​used as the reference curve and 50A is used as the reference point. The initial duty cycle is calculated based on the power consumption requirements of the device being used (cable online monitoring device). When the device is working, when the current continues to rise, the duty cycle output continues to decrease to provide a larger input power; when the current decreases due to the increase in input voltage, the duty cycle output continues to increase, stabilizing the input power.

[0040] In some embodiments, the energy acquisition module further includes a DC power supply energy acquisition module 24 .

[0041] In this embodiment, the energy collection device can also directly draw power from an external DC power supply, further improving the diversity of power collection methods and improving the reliability of power collection. The DC power supply energy collection module 24 draws energy as an emergency backup input, and the energy collection device mainly draws power through the above-mentioned solar energy collection module 21, cable coupling energy collection module 22 and AC power collection module 23. The DC power supply energy collection module 24 is preferably a USB DC power supply energy collection module, which is easy to connect and has strong versatility. When the power collection device has no other input, the power collection device has emergency work, and common USB charging sources such as mobile phone power banks can be used as input.

[0042] In some embodiments, the energy acquisition device also includes multiple energy distribution modules 3, and the multiple energy distribution modules 3 are respectively connected to the power control conversion circuit 1, and the power control conversion circuit 1 distributes the energy acquired by the energy acquisition module 2 to the corresponding energy distribution module 3.

[0043] In this embodiment, through multiple energy distribution modules 3 connected to the power control conversion circuit 1, reasonable path distribution management can be performed on the energy obtained by the energy acquisition device to avoid repeated restarts of the energy acquisition device under low load, thereby improving energy utilization efficiency.

[0044] In some embodiments, the energy distribution module 3 includes a 12V output unit 31 , a 24V output unit 32 and an energy storage unit 33 .

[0045] Energy usage distribution includes energy output path (12V output unit 31, 24V output unit 32) and energy storage path (energy storage unit 33). The output ends of multiple energy extraction modules 2 are respectively connected to the energy storage unit 33 to store the energy obtained through different energy extraction methods in the energy storage unit 33, and reasonably distribute it according to the actual power supply needs, output a part of the energy through the 12V output unit 31 and the 24V output unit 32 to the cable online monitoring equipment, and store the other part of the energy in the energy storage unit 33, so as to effectively deal with the insufficient power extraction of the energy extraction device. For example, when the above-mentioned multiple power extraction modules 2 are insufficient in power extraction, the energy stored in the energy storage unit 33 can be used to power the power extraction device itself or the cable online monitoring equipment.

[0046] The energy storage unit 33 is preferably a storage battery, which is built into the energy extraction device. The storage battery is preferably a high-performance lithium-ion battery, which can cope with the power shortage valley period of more than 96 hours of the power extraction device, and effectively ensure the power extraction reliability of the power extraction device.

[0047] In some embodiments, Figure 2 As shown, the power control conversion circuit 1 includes a charging circuit, which is respectively connected to the solar energy acquisition module 21, the cable coupling energy acquisition module 22, and the mains energy acquisition module 23 to charge the energy acquisition device.

[0048] The solar energy acquisition module 21 is connected to the energy storage unit 33 through a first charging circuit (solar energy charging circuit with MPPT), the cable-coupled energy acquisition module 22 is connected to the energy storage unit 33 through a second charging circuit, and the AC power acquisition module 23 is connected to the energy storage unit 33 through a third charging circuit.

[0049] The circuit connecting the cable-coupled energy extraction module 22 and the power control conversion circuit 1 also includes a wide-range voltage input DC / DC converter to cope with certain specific occasions such as the input voltage exceeding the normal variation range and fluctuating within a wider range, while also being able to increase the power level.

[0050] In some embodiments, a protection circuit is provided in the connection circuit between the power control conversion circuit 1 and the cable-coupled energy extraction module 22 .

[0051] The circuit in which the AC power acquisition module 23 is connected to the power control conversion circuit 1 also includes an AC / DC power supply module to effectively convert the acquired AC power into the required energy.

[0052] The power control conversion circuit 1 connected to the DC power supply and energy acquisition module 24 includes a DC output conversion circuit (DC / DC), which is connected between the DC power supply and energy acquisition module 24 and the energy storage unit 33, and can realize efficient conversion of DC power supply to meet the voltage and current requirements of different devices.

[0053] Furthermore, the energy storage unit 33 includes a charging mode and a discharging mode, and the charging mode and the discharging mode are switched according to the energy acquired by the energy acquisition module 2;

[0054] Among them, if the energy obtained by the energy acquisition module 2 is less than the first preset energy threshold, the charging mode is turned off; if the energy obtained by the energy acquisition module 2 is greater than the second preset energy threshold, the charging mode is turned on; if the energy obtained by the energy acquisition module 2 is zero, the energy release mode is turned on.

[0055] In this embodiment, an independent backup energy storage unit (different from the above-mentioned battery) can be set up, which is specifically used for charging and discharging the energy storage unit 33 (battery) to prevent dangerous behaviors such as overcharging and over-discharging of the energy storage unit 33. When the energy storage unit 33 can fluctuate in the comprehensive energy extraction peak and valley through each energy extraction module 2, in order to avoid severe load fluctuations, the charging and discharging of the energy storage unit 33 is controlled by the backup energy storage unit to stabilize the external output power of the energy extraction device.

[0056] The energy distribution management strategy of the backup energy storage unit is that when the energy storage unit 33 obtains less energy through the above-mentioned different energy acquisition modules 2, the charging mode of the backup energy storage unit is turned off, thereby turning off the charging of the energy storage unit 33, ensuring the external function of the energy acquisition device (powering the cable online monitoring equipment), avoiding repeated restarts of external devices such as the cable online monitoring equipment due to insufficient energy acquisition, and ensuring the operation of external devices. When the energy storage unit 33 obtains more energy than the external output demand through the above-mentioned different energy acquisition modules 2, the charging mode of the backup energy storage unit is turned on, and the charging of the energy storage unit 33 is turned on, and the excess energy is stored in the energy storage unit 33 for subsequent use, and energy waste is avoided, and energy utilization and efficiency are improved. When the energy storage unit 33 obtains zero energy through the above-mentioned different energy acquisition modules 2, the backup energy storage unit turns on the energy release mode to maintain the energy supply to the external equipment until the energy storage unit 33 turns on the low voltage protection.

[0057] It is understandable that the above-mentioned backup energy storage unit can also be an integrated structure with the battery that obtains energy through each energy extraction module 2, that is, the energy storage unit 33 does not need to be provided with an independent backup energy storage unit, and the energy storage unit 33 is charged and discharged according to its own comprehensive energy extraction situation.

[0058] From the above, it can be seen that the cable online monitoring equipment provided by the embodiment of the present disclosure can not only flexibly select the energy acquisition method according to the installation environment of the online monitoring equipment, thereby improving the power acquisition reliability and the online rate of the online monitoring equipment; it can also reasonably use and allocate the acquired energy, thereby avoiding repeated restarts of the cable online monitoring equipment under low load, and improving energy utilization and efficiency.
