[0027] The distribution switch monitoring terminal (FTU for short) is an intelligent device installed next to the feeder switch such as the pole-mounted circuit breaker. It is a comprehensive automation device that integrates measurement, protection, monitoring and communication. It is widely used in urban and rural 10kV overhead distribution line users. It is installed at the responsibility demarcation point of the 10kV overhead distribution line. It can automatically cut off single-phase grounding faults and automatically isolate interphase short-circuit faults to ensure the power safety of non-fault users.

[0028] However, when a power outage occurs due to circuit problems, the distribution switch monitoring terminal will also lack power due to the inability of the distribution line to supply power normally and will no longer be able to work normally. This also makes it impossible for operators to remotely learn the working status of the feeder switch and effectively monitor circuit problems, greatly affecting the availability of the distribution switch monitoring terminal.

[0029] In order to improve or solve the above technical problems, the inventors of the present application have proposed at least the following embodiments after long-term research.

[0030] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, Figure 1 It is a schematic diagram of the assembly structure of the monitoring device provided in the present application installed on the supporting structure. Figure 2 It is a schematic diagram of the assembly structure of an embodiment of the monitoring device provided by the present application. Figure 3 It is a structural schematic diagram of another angle of an embodiment of the monitoring device provided by the present application. Figure 4 The embodiment of the present application provides a monitoring device 1 for a power distribution switch monitoring terminal, and the monitoring device 1 for a power distribution switch monitoring terminal may include a power supply component and a monitoring component 3 .

[0031] The power supply component may include a solar panel 21, an energy storage battery 22, and a power controller 23. The energy storage battery 22 is connected to the solar panel 21 and the power controller 23, and the power controller 23 is used to connect the distribution switch monitoring terminal and the main power supply for connecting the distribution switch monitoring terminal. The power controller 23 can control at least one of the main power supply and the energy storage battery 22 to be connected to the distribution switch monitoring terminal. The monitoring component 3 may include a camera 31 and a communication component, the camera 31 and the communication component are connected to the energy storage battery 22, and the communication component is used to output the image captured by the camera 31.

[0032] The power controller 23 is used to manage the input and output of electric energy. It can adopt a DC dual power automatic switching circuit with dual 24V input and single 24V output. The main power supply is a DC (Direct Current) 24V voltage taken from the transmission line. When the transmission line is out of power, the power control module detects that the main power supply voltage is abnormal and automatically connects the 24V backup power supply voltage provided by the battery to the circuit to complete the power connection. The switching time can reach 7ms, which meets the power supply usage needs of the distribution switch monitoring terminal.

[0033] Different from the prior art, in the structure provided in this embodiment, the solar panel 21 of the power supply component can use solar energy to charge the energy storage battery 22, and the power controller 23 can control the energy storage battery 22 to replace or assist the main power supply to supply power to the distribution switch monitoring terminal, so that the normal operation of the distribution switch monitoring terminal can be maintained when the main power supply cannot work normally, so that the distribution switch monitoring terminal can monitor and report the faults generated by the distribution line where the main power supply is located. The monitoring component 3 is powered by the energy storage battery 22, and can cooperate with the distribution switch monitoring terminal to monitor the working conditions and fault conditions of the distribution line more accurately and in detail, greatly improving the availability and versatility of the distribution switch monitoring terminal.

[0034] Optionally, the energy storage battery 22 can specifically be a lithium iron phosphate battery. Common batteries are usually lead-acid batteries. Although this type of battery is a mature technology as a backup power source, it has many shortcomings during long-term use, such as limited life, the need for regular maintenance and replacement, and sensitivity to ambient temperature. The performance of lead-acid batteries decreases significantly in low temperature environments, and the capacity decreases, affecting the reliable operation of the FTU. Furthermore, lead-acid batteries contain heavy metals, which will cause environmental pollution and are not in line with the development trend of green and environmental protection. Compared with traditional lead-acid batteries, lithium iron phosphate batteries have the characteristics of long life, high safety, light weight and small size, and environmental protection and pollution-free. The cycle life of lithium iron phosphate batteries can generally reach more than 2,000 times.

[0035] Preferably, the energy storage battery 22 can be a 24V lithium iron phosphate battery. The voltage level of the battery is increased from the common 12V to 24V, which is consistent with the voltage level of the power supply of the distribution switch monitoring terminal, reducing the energy loss caused by the voltage boost. The battery can power the distribution switch monitoring terminal and the camera 31 at the same time.

[0036] Optionally, the solar panel 21 can assist the battery in supplying power and reduce battery power consumption.

[0037] Optionally, the energy storage battery 22 may include multiple groups. When the energy storage battery 22 needs to supply power, one of them is used for discharging, and the solar panel 21 can charge at least one of the remaining ones, thereby cooperating with the solar panel 21 to maintain long-term power supply.

[0038] Optionally, the communication mode of the communication component outputting the image may be wireless communication and / or wired communication. Preferably, the communication mode of the communication component is wireless communication. Conventional power monitoring usually relies on wired communication modes, such as optical fiber or cable. The wired communication mode has problems such as complex wiring, high maintenance cost, and poor flexibility, which is not conducive to the distribution switch monitoring terminal and the monitoring device 1 for the distribution switch monitoring terminal to be widely deployed.

[0039] Preferably, the communication mode of the communication component is 4G communication. The communication component can use 4G communication to connect to the client where the off-site workers are located, so that the off-site workers can learn about the on-site situation through the client.

[0040] Optionally, the communication component also includes a telesignaling module, which refers to the switching quantity of telecontrol communication data. The telesignaling module can be connected to the distribution switch monitoring terminal 1 and / or the feeder switch in a passive contact manner. The telesignaling module is used to transmit the device status signal of the monitored feeder switch to the client, so that the operator who is not on site can perform remote real-time monitoring through the client. The device status signal of the monitored feeder switch may include at least one of the switch position signal, the transformer internal fault comprehensive signal, the protection device action signal, the communication equipment operation status signal, the voltage regulating transformer tap position signal and the like.

[0041] In a specific embodiment of the present application, the monitoring device 1 for the distribution switch monitoring terminal may further include a box 4. The box 4 may be provided with an installation space 41, and the energy storage battery 22 and the power controller 23 are arranged in the installation space 41, so that the box 4 can be used to protect the energy storage battery 22 and the power controller 23, reduce the probability of water ingress, sun aging, wind blowing, etc., and extend the practical life of the monitoring device 1 for the distribution switch monitoring terminal.

[0042] The solar panel 21 and the camera 31 can be arranged on the side of the box 4 away from the installation space 41, that is, facing the outside world, so that the solar panel 21 can absorb light energy, and the camera 31 can shoot the distribution line, feeder switch, distribution switch monitoring terminal and other equipment, as well as the external environment, to achieve the purpose of monitoring.

[0043] Specifically, the box body 4 may include a box door 4a, a box wall 4b, and a waterproof cover 4c. The installation space 41 is arranged in the box wall 4b, and the box wall 4b has an opening connecting the installation space 41 with the outside world. The box door 4a is rotatably installed at the opening, and the box door 4a can be rotated to be engaged with the box wall 4b to cover the opening, thereby isolating the outside world from the installation space 41. The box door 4a can also be rotated to open the opening, so that the outside world is connected with the installation space 41. The waterproof cover 4c is connected to the box body 4, and the waterproof cover 4c is arranged above the box wall 4b and the box door 4a. The waterproof cover 4c can cover the box wall 4b, the box door 4a and the seam between the two in the vertical direction, and play a role of sun protection and waterproofing.

[0044] Optionally, the solar panel 21 can be installed on the door 4a. The monitoring assembly 3 can also include a camera fixture 35, one end of which is fixed to the solar panel 21 and the other end is connected to the camera 31, so that the camera 31 and the solar panel 21 are relatively fixed.

[0045] During the charging and discharging process of the energy storage battery 22, the conversion efficiency between chemical energy and electrical energy is not 100%, and a part of it is inevitably converted into heat energy, which causes a certain amount of heating of the energy storage battery 22. In a specific embodiment of the present application, the monitoring device 1 for the distribution switch monitoring terminal may also include a cooling fan 42, a temperature controller 43 and a temperature sensor 44. The box 4 is provided with a fan mounting hole 49 corresponding to the cooling fan 42, and the cooling fan 42 is arranged at the fan mounting hole 49, and the fan mounting hole 49 is used to connect the outside and the installation space 41. The temperature sensor 44 is arranged in the installation space 41 and adjacent to the energy storage battery 22, and the temperature controller 43 connects the temperature sensor 44 and the cooling fan 42.

[0046] Through the structure provided in this embodiment, the temperature sensor 44 can be used to detect the temperature near the energy storage battery 22, and the temperature controller 43 can make a judgment based on the data measured by the temperature sensor 44, so as to control whether the cooling fan 42 works and at what power it works according to the actual heating condition of the energy storage battery 22, so as to effectively dissipate the heat of the energy storage battery 22 and the installation space 41, reduce the probability of overheating, and reduce safety hazards.

[0047] Specifically, the cooling fan 42 , the temperature controller 43 , and the temperature sensor 44 may be connected to the energy storage battery 22 and powered by the energy storage battery 22 .

[0048] Furthermore, heat dissipation control can be performed by setting multiple threshold ranges. For example, when the data measured by the temperature sensor 44 is within a specified threshold range, the temperature controller 43 controls the heat dissipation fan 42 to start working and / or to work at a power corresponding to the threshold range. When the data measured by the temperature sensor 44 is not within the threshold range, the temperature controller 43 can control the heat dissipation fan 42 to stop working to save power.

[0049] In a specific embodiment of the present application, the box body 4 may include a working status indicator light 45, which may be arranged on a side of the box body 4 away from the installation space 41, and the working status indicator light 45 is connected to at least one of the power controller 23 and the temperature controller 43.

[0050] Through the structure provided in this embodiment, the working status indicator light 45 can be used to display the power supply information currently used to supply power to the distribution switch monitoring terminal, such as whether the power supply is the main power supply or the energy storage battery 22, and whether the remaining power in the energy storage battery 22, whether the main power supply can work normally, etc. The working status indicator light 45 can also be used to display the temperature near the current energy storage battery 22, whether there are problems such as overheating. On-site operators can quickly obtain this information through the working status indicator light 45, which can improve the availability of the distribution switch monitoring terminal and its monitoring device 1. At the same time, when the camera 31 captures the working status indicator light 45, this information can also be intuitively presented to operators who are not on site.

[0051] In a specific embodiment of the present application, the monitoring device 1 for the distribution switch monitoring terminal may further include a fixing component, which includes a clamping band 46, a clamping base 47 and a fastening bolt 48. Both ends of the clamping band 46 are provided with a first fastening screw hole 461, the clamping base 47 is provided with a second fastening screw hole 471, and the clamping base 47 is relatively fixed to the box body 4. The clamping band 46 is used to surround the support structure 5 provided with the distribution switch monitoring terminal, and the fastening bolt 48 is screwed with the first fastening screw hole 461 and the second fastening screw hole 471.

[0052] The clamping method can be applied to the support structure 5 such as the tower pole for installing the distribution switch monitoring terminal. Through the structure provided in this embodiment, the clamping band 46 can be used to surround the support structure 5, and then the two ends of the clamping band 46 can be locked with the clamping base 47 by the fastening bolts 48, so that the monitoring device can be fixed to the support structure 5 near the distribution switch monitoring terminal by the clamping method.

[0053] Optionally, a light absorbing portion 211 is provided on one side surface of the solar panel 21, and the light absorbing portion 211 is used to absorb light energy. The monitoring device 1 for the power distribution switch monitoring terminal may also include a first mounting assembly 24 and a second mounting assembly 25. The first mounting assembly 24 includes a first mounting member 241 and a second mounting member 242, the first mounting member 241 is arranged at one end of the solar panel 21, and the second mounting member 242 is arranged at the upper end of the box 4. The end of the first mounting member 241 away from the solar panel 21 is connected to the end of the second mounting member 242 away from the box 4.

[0054] The second mounting assembly 25 includes a third mounting member 251, a fourth mounting member 252 and a support rod 26. The third mounting member 251 is disposed at an end of the solar panel 21 away from the first mounting member 241, and the fourth mounting member 252 is disposed at the lower end of the box 4. One end of the support rod 26 is connected to an end of the third mounting member 251 away from the solar panel 21, and the other end of the support rod 26 is connected to an end of the fourth mounting member 252 away from the box 4.

[0055] The first mounting member 241 has the same length as the third mounting member 251, and the second mounting member 242 has the same length as the third mounting member 251. By connecting the support rod 26 between the third mounting member 251 and the fourth mounting member 252, one end of the solar panel 21 is propped up, so that the surface of one side of the solar panel 21 with the light absorbing portion 211 faces upward, so that the light absorbing portion 211 can effectively absorb light.

[0056] Optionally, the number of the first mounting assembly 24 and the second mounting assembly 25 can both be two, and they are symmetrically arranged, so as to evenly and stably support the solar panel 21 .

[0057] Furthermore, the tilt angle of the solar panel 21 can be adjusted by manually replacing the support rod 26 so that the light absorbing portion 211 faces a direction more suitable for absorbing light.

[0058] Optionally, the monitoring component 3 is disposed adjacent to one end of the solar panel 21 where the first mounting member 241 is provided.

[0059] In a specific embodiment of the present application, the monitoring device 1 for the distribution switch monitoring terminal may further include a photosensitive member and a driving member, wherein the driving member connects the photosensitive member and the energy storage battery 22. The orientation of the photosensitive member is the same as that of the light absorbing portion 211, and the photosensitive member is relatively fixed to the solar panel 21, and the driving member is used to drive the solar panel 21 to rotate until the light absorbing portion 211 and the photosensitive member face the light source.

[0060] Through the structure provided in this embodiment, the photosensitive element can be used to sense the intensity of light, so that the solar panel 21 can rotate along with the light source when driven by the driving element, and the light absorbing part 211 can be arranged toward the light source as much as possible, which can improve the efficiency of the solar panel 21 in absorbing light energy, thereby accelerating the energy storage speed of the energy storage battery 22.

[0061] like Figure 5 As shown, Figure 5 3 is a schematic diagram of the exploded structure of the monitoring component provided by the present application. In a specific embodiment of the present application, the monitoring component 3 may also include a camera waterproof component, which includes a waterproof cover 32 and a waterproof shell 33. The waterproof cover 32 and the waterproof shell 33 are buckled to form a water-proof space 34 isolated from the outside world, and the camera 31 includes a lens 311 and a body 312. The waterproof cover 32 is set on the periphery of the lens 311, and the waterproof shell 33 is set on the periphery of the body 312. The waterproof cover 32 is a transparent part.

[0062] Many distribution line failures occur in rainy weather, but rain can cause water to enter the camera 31, or it is difficult to capture a clear image due to water droplets. Through the structure provided in this embodiment, the camera 31 can be waterproofed by using the waterproof cover 32 and the waterproof shell 33. The transparent waterproof cover 32 enables the lens 311 of the camera 31 to adapt to various climatic conditions, thereby improving the availability of the monitoring component 3.

[0063] In a specific embodiment of the present application, the monitoring component 3 may also include an image recognition component, which is connected to the camera 31 and the communication component.

[0064] Furthermore, the recognition result of the image recognition element, the image captured by the camera 31, and the situation reported by the distribution switch monitoring terminal can be reflected and compared with each other, so that the staff can make an accurate judgment on the actual situation.

[0065] Optionally, the camera 31 may be a camera dome camera. The camera dome camera may have a dual-motor pan / tilt head, which can rotate 360 ​​degrees left and right and 90 degrees up and down, thereby providing a full range of viewing angle adjustment, so as to capture the details of the circuit breaker and the surrounding environment. The staff can control the rotation of the lens 311 of the camera 31 according to the needs, so as to monitor different directions and positions, and meet the needs of different usage scenarios.

[0066] The embodiment of the present application also provides a power switching method, using the monitoring device 1 for a distribution switch monitoring terminal as described in any one of the above-mentioned specific embodiments.

[0069] Different from the prior art, in the method provided in this embodiment, the solar panel 21 of the power supply component can use solar energy to charge the energy storage battery 22, and the power controller 23 can control the energy storage battery 22 to replace or assist the main power supply to supply power to the distribution switch monitoring terminal, so that the normal operation of the distribution switch monitoring terminal can be maintained when the main power supply cannot work normally, so that the distribution switch monitoring terminal can monitor and report the faults generated by the distribution line where the main power supply is located. The monitoring component 3 is powered by the energy storage battery 22, and can cooperate with the distribution switch monitoring terminal to monitor the working conditions and fault conditions of the distribution line more accurately and in detail, greatly improving the availability and versatility of the distribution switch monitoring terminal.

[0070] In a specific implementation of the present application, after the power controller 23 determines whether the main power supply can supply power normally, it also includes:

[0071] S300: In response to the main power supply being able to supply power normally, the power controller 23 maintains the connection between the main power supply and the distribution switch monitoring terminal, and connects the main power supply and the energy storage battery 22, and uses the main power supply to charge the energy storage battery 22.

[0072] The power supply or charging of the solar panel 21 depends on the climatic conditions. In a weak light environment, such as the rainy season, there is too little light energy available, and it is difficult for the solar panel 21 to charge the energy storage battery 22. However, the rainy season is also a season when power distribution line failures are frequent. The lack of power in the energy storage battery 22 in some environments will affect the availability of the monitoring device. Through the method provided in this embodiment, when the main power supply is normally supplied, the energy storage battery 22 can be charged by the main power supply, so that it can adapt to different climatic conditions, reduce the probability of accidents such as the energy storage battery 22 running out of power when the main power supply fails, so that the energy storage battery 22 can always have a certain amount of power to deal with emergencies, and can improve the versatility and availability of the monitoring component 3.

[0073] Optionally, the solar panel 21 and the main power supply can charge the energy storage battery 22 at the same time, thereby increasing the charging speed of the energy storage battery 22 and further improving the availability of the monitoring component 3.

[0074] The above description is only part of the implementation methods of the present application, and does not limit the protection scope of the present application. Any equivalent device or equivalent process transformation made using the contents of the present application specification and drawings, or directly or indirectly used in other related technical fields, are also included in the patent protection scope of the present application.
