Description

Technical Field

[0001] This invention relates to the field of power detection technology, and in particular to an intelligent ring network cabinet based on big data. Background Technology

[0002] A ring main unit (RMU) is an electrical device consisting of a group of power transmission and distribution equipment (high-voltage switchgear) housed in a metal or non-metal insulated cabinet or assembled into a modular ring network power supply unit. Its core components include circuit breakers, load switches, and fuses. It offers advantages such as simple structure, small size, low cost, improved power supply parameters and performance, and enhanced power supply safety. It is widely used in substations and prefabricated substations in load centers such as urban residential areas, high-rise buildings, large public buildings, and factories.

[0003] A ring network refers to a ring-shaped distribution network, where the main power supply line forms a closed loop. Power is supplied to this ring-shaped main line, and then distributed outwards through high-voltage switches. The advantage of this is that each distribution branch can draw power from both its left and right main lines. If a fault occurs on the left main line, it continues to receive power from the right main line, and vice versa. Thus, although the total power supply is a single source, each distribution branch benefits from what is equivalent to dual power supply, thereby improving power reliability.

[0004] A "ring mains unit" is a switchgear unit where each distribution branch has its own switchgear, and the busbar of this switchgear unit is also part of the ring main line. In other words, the ring main line is formed by connecting the busbars of each group of incoming and outgoing switchgear units. A group of incoming and outgoing switchgear units is called a "ring mains unit." In reality, looking at a single ring mains unit alone doesn't reveal the meaning of "ring mains."

[0005] Chinese Patent Publication No. CN104577742A discloses a ring main unit for wirelessly detecting temperature and humidity and wirelessly outputting data. The unit includes a ring main unit module and a detection system. The detection system comprises a wireless detection transmitting system and a receiving system. The wireless detection transmitting system is fixed inside the ring main unit module and includes a humidity sensor, a temperature sensor, and a wireless transmitter. The receiving system is located outside the ring main unit. Therefore, current ring main units only detect temperature and humidity within the unit, lacking environmental monitoring. Excessively high temperature and humidity in the external environment will diffuse into the unit, requiring subsequent adjustments based on the internal temperature and humidity conditions. This adjustment efficiency is lagging and affects the internal working state of the ring main unit. Summary of the Invention

[0006] To address this, the present invention provides an intelligent ring main unit based on big data, which overcomes the problem that the temperature and humidity detection of current ring main units is limited to the inside of the unit and lacks environmental detection. Excessive temperature and humidity in the external environment will diffuse into the unit, and then adjustments will be made according to the temperature and humidity inside the unit. This results in a lag in adjustment efficiency and affects the working status of the ring main unit.

[0007] To achieve the above objectives, the present invention provides an intelligent ring network cabinet based on big data, comprising:

[0008] cabinet,

[0009] A power detection module, which is installed inside the cabinet, is used to detect real-time power data;

[0010] A humidity detection module is installed inside the cabinet to detect the humidity level inside the cabinet.

[0011] A temperature detection module is installed inside the cabinet to detect the temperature inside the cabinet.

[0012] A temperature and humidity control device is installed inside the cabinet to regulate the temperature and humidity inside the cabinet.

[0013] Ventilation holes are provided on the side wall of the cabinet for ventilation. The ventilation holes have two modes: open and closed.

[0014] An external environment detection module is installed outside the cabinet to detect the external environment of the ring main unit;

[0015] A video detection module is installed inside the ring main unit to detect the video situation inside the ring main unit;

[0016] A fire-prevention device is installed on one side of the video detection module and contains a substance with fire-extinguishing function.

[0017] The central control system is connected to the power detection module, humidity detection module, temperature detection module, ventilation vent, external environment detection module, temperature and humidity adjustment device, video detection module, and fire prevention device, respectively, to adjust the working status of each component. The central control system can determine whether to adjust the temperature and humidity based on the acquired temperature and humidity information inside the cabinet, and can control the opening and closing of the ventilation vents based on the relationship between the ambient temperature and the temperature inside the cabinet.

[0018] Furthermore, the temperature detection module detects the temperature inside the cabinet and transmits the detected temperature result to the central control system.

[0019] The central control system is equipped with a high temperature threshold. When the detected temperature inside the cabinet reaches the threshold, the central control system controls the temperature and humidity regulating device to start and regulate the temperature inside the cabinet.

[0020] Furthermore, the humidity detection module detects the humidity level inside the cabinet and transmits the detected humidity result to the central control system.

[0021] The central control system is equipped with a humidity threshold. When the detected humidity inside the cabinet reaches the threshold, the central control system controls the temperature and humidity adjustment device to start and adjust the humidity inside the cabinet.

[0022] Furthermore, the central control system is connected to the external environment detection module, which can detect the environment around the ring main unit, conduct risk assessment in advance, and control the temperature and humidity regulation device to regulate the temperature and humidity inside the unit.

[0023] Furthermore, the external environment detection module detects the ambient temperature and humidity, and compares the ambient temperature and humidity with the temperature and humidity inside the cabinet, respectively, and adjusts the opening and closing of the heat dissipation holes based on the comparison results.

[0024] Furthermore, when the ambient temperature is higher than the temperature inside the cabinet and the ambient humidity is higher than the humidity inside the cabinet, the central control system controls the ventilation holes to close.

[0025] When the ambient temperature is lower than the temperature inside the cabinet and the ambient humidity is lower than the humidity inside the cabinet, the central control system controls the ventilation holes to open.

[0026] When the ambient temperature is lower than the temperature inside the cabinet and the ambient humidity is higher than the humidity inside the cabinet, or when the ambient temperature is higher than the temperature inside the cabinet and the ambient humidity is lower than the humidity inside the cabinet, the central control system determines whether to open or close the ventilation holes based on the temperature difference and humidity difference.

[0027] Furthermore, when the temperature and humidity control device is turned on to cool the cabinet, the temperature detection device detects the temperature change curve inside the cabinet. When the temperature change curve is less than the preset expected temperature drop curve, the central control system determines that the temperature inside the cabinet is abnormally rising and sends abnormal information to the remote control center.

[0028] Furthermore, the slope of the expected temperature decrease curve is related to the external temperature of the cabinet.

[0029] Furthermore, when the temperature and humidity control device is used to cool the inside of the cabinet, the external environment detection module collects the temperature outside the cabinet at this time and compares the temperature outside the cabinet with the high temperature threshold. When the temperature outside the cabinet is higher than the high temperature threshold, the ventilation hole is closed.

[0030] Furthermore, the video detection module can detect image information inside the cabinet, and when a fire source appears inside the ring main unit, the fire prevention device is activated to extinguish the fire.

[0031] Compared with the prior art, the beneficial effects of the present invention are that by monitoring the environment, the working status of each component in the ring main unit can be reasonably adjusted, so that the temperature and humidity inside the ring main unit are within the ideal operating range in real time. On the one hand, this improves the accuracy of power monitoring data, and on the other hand, it extends the maintenance interval of the equipment and reduces maintenance expenses.

[0032] Furthermore, by detecting the temperature inside the cabinet and controlling the automatic start of the temperature and humidity control device, the temperature inside the ring main unit is kept within the ideal operating range in real time. This improves the accuracy of power detection data and extends the maintenance interval of the equipment, reducing maintenance costs. When the temperature drops below the high temperature threshold, the temperature and humidity control device is set to stop operating at a temperature lower than the high temperature threshold. This prevents the temperature inside the cabinet from rising above the high temperature threshold in a short period of time after stopping, further ensuring the temperature stability of the ring main unit during operation.

[0033] Furthermore, by detecting the humidity inside the cabinet and controlling the automatic start of the temperature and humidity control device, the humidity inside the ring main unit is kept within the ideal operating range in real time. This improves the accuracy of power detection data and extends the maintenance interval of the equipment, reducing maintenance costs. When the humidity reaches below the humidity threshold, the temperature and humidity control device is set to stop operating, and the humidity at the stop is lower than the humidity threshold. This prevents the humidity inside the cabinet from rising above the humidity threshold in a short period of time after stopping, further ensuring the humidity stability inside the ring main unit during operation.

[0034] Furthermore, when the temperature and humidity of the environment where the ring main unit is located are higher than the temperature and humidity thresholds for operation inside the ring main unit, the temperature and humidity of the environment will diffuse into the ring main unit. In order to ensure that the temperature and humidity inside the ring main unit are within a reasonable operating range, the temperature and humidity regulation device is activated in advance to prevent the internal temperature and humidity from rising due to the diffusion of external temperature and humidity into the ring main unit. This preventive measure ensures that the internal temperature and humidity of the ring main unit are within a reasonable range, further guaranteeing the stability of the ring main unit during operation.

[0035] Furthermore, when the temperature and humidity of the environment where the ring main unit is located are higher than the temperature and humidity inside the ring main unit, the temperature and humidity of the environment will diffuse into the ring main unit. In order to ensure that the temperature and humidity inside the ring main unit are within a reasonable operating range, the opening and closing of the ventilation holes are reasonably controlled to ensure the stability of the ring main unit during operation.

[0036] Furthermore, if the cooling requirement is not met when cooling the ring main unit, it indicates abnormal heating inside the unit. Therefore, by checking and analyzing the temperature drop curve, it is possible to determine whether there is abnormal heating inside the unit, identify the problem in time, and resolve it as soon as possible to prevent damage to power equipment caused by monitoring delays.

[0037] Furthermore, when the external temperature of the cabinet is higher than the high temperature threshold, the external temperature is not conducive to cooling inside the cabinet, so the value of the temperature drop reference slope is increased at this time; when the external temperature of the cabinet is lower than the high temperature threshold, the external temperature is conducive to cooling inside the cabinet, so the value of the temperature drop reference slope is decreased at this time; by adjusting the value of the temperature drop reference slope, the slope comparison is made more accurate.

[0043] Please see Figure 1 As shown, Figure 1 This is a schematic diagram of a smart ring main unit based on big data, as described in an embodiment of the present invention. The present invention provides a smart ring main unit based on big data, comprising:

[0044] Cabinet 1,

[0045] The power detection module 2 is installed inside the cabinet 1 to detect real-time power data;

[0046] Humidity detection module 3 is installed inside the cabinet 1 to detect the humidity inside the cabinet 1;

[0047] Temperature detection module 4 is installed inside the cabinet 1 to detect the temperature inside the cabinet 1;

[0048] Temperature and humidity control device 5 is installed inside the cabinet 1 to regulate the temperature and humidity inside the cabinet 1;

[0049] Ventilation hole 6 is provided on the side wall of the cabinet 1 for ventilation. The ventilation hole has two modes: open and closed.

[0050] External environment detection module 7 is located outside the cabinet 1 and is used to detect the external environment of the ring main unit;

[0051] The video detection module 8 is installed inside the ring main unit and is used to detect the video situation inside the ring main unit.

[0052] Fire prevention device 9, which is located on one side of the video detection module 8, contains a substance with fire extinguishing function;

[0053] The central control system 10 is connected to the power detection module 2, the humidity detection module 3, the temperature detection module 4, the ventilation vent 6, the external environment detection module 7, the temperature and humidity adjustment device 5, the video detection module 8, and the fire prevention device 9, respectively, to adjust the working status of each component. The central control system 10 can determine whether to adjust the temperature and humidity based on the acquired temperature and humidity information inside the cabinet 1, and can control the opening and closing of the ventilation vents based on the relationship between the ambient temperature and the temperature inside the cabinet 1.

[0054] By monitoring the environment and rationally adjusting the working status of each component inside the ring main unit, the temperature and humidity inside the ring main unit are kept within the ideal operating range in real time. This improves the accuracy of power monitoring data and extends the maintenance interval of the equipment, thereby reducing maintenance costs.

[0055] Specifically, the temperature detection module detects the temperature W inside the cabinet 1 and transmits the detected temperature result to the central control system 10.

[0056] The central control system 10 is equipped with a high-temperature threshold Wz. The central control system 10 compares the temperature W with the high-temperature threshold Wz.

[0057] When W≤Wz, the central control system 10 will not activate the temperature and humidity control device 5 due to the temperature inside the ring network cabinet;

[0058] When W > Wz, the central control system 10 controls the temperature and humidity regulating device 5 to start the cooling mode. The temperature and humidity regulating device 5 cools down the temperature inside the cabinet 1. During the cooling process, the temperature detection module detects the temperature W' inside the cabinet 1 in real time and transmits the detection result to the central control system 10. The central control system 10 compares the temperature W' with 0.8 times Wz.

[0059] When W'≤0.8Wz, the central control system 10 controls the temperature and humidity regulating device 5 to turn off the cooling mode;

[0060] When W' > 0.8Wz, the central control system 10 controls the temperature and humidity regulating device 5 to continue operating in cooling mode until W' ≤ 0.8Wz.

[0061] By detecting the temperature inside cabinet 1, the automatic start of the temperature and humidity control device 5 is controlled, ensuring that the temperature inside the ring main unit is within the ideal operating range in real time. This improves the accuracy of power detection data and extends the maintenance interval of the equipment, reducing maintenance costs. When the temperature drops below the high temperature threshold, the temperature and humidity control device 5 is set to stop operating at a temperature lower than the high temperature threshold. This prevents the temperature inside cabinet 1 from rising above the high temperature threshold in a short period of time after stopping, further ensuring the temperature stability of the ring main unit during operation.

[0062] Specifically, the humidity detection module detects the humidity S inside the cabinet 1 and transmits the detected humidity result to the central control system 10.

[0063] The central control system 10 is equipped with a humidity threshold Sz. The central control system 10 compares the humidity S with the humidity threshold Sz.

[0064] When S≤Sz, the central control system 10 will not activate the temperature and humidity regulating device 5 due to the humidity inside the ring network cabinet;

[0065] When S > Sz, the central control system 10 controls the temperature and humidity regulating device 5 to start the dehumidification mode. The temperature and humidity regulating device 5 dehumidifies the cabinet 1. During the dehumidification process, the humidity detection module detects the humidity S' inside the cabinet 1 in real time and transmits the detection result to the central control system 10. The central control system 10 compares the humidity S' with 0.9 times Sz.

[0066] When S'≤0.9Sz, the central control system 10 controls the temperature and humidity regulating device 5 to turn off the dehumidification mode;

[0067] When S' > 0.9Sz, the central control system 10 controls the temperature and humidity regulating device 5 to continue operating in dehumidification mode until S' ≤ 0.9Sz.

[0068] By detecting the humidity inside cabinet 1, the automatic start of the temperature and humidity control device 5 is controlled, ensuring that the humidity inside the ring main unit is within the ideal operating range in real time. This improves the accuracy of power detection data and extends the maintenance interval of the equipment, reducing maintenance costs. When the humidity reaches below the humidity threshold, the temperature and humidity control device 5 is set to stop operating, and the humidity at the stop is lower than the humidity threshold. This prevents the humidity inside cabinet 1 from rising above the humidity threshold in a short period of time after stopping, further ensuring the humidity stability of the ring main unit during operation.

[0069] Specifically, the central control system 10 is connected to the external environment detection module 7, which can detect the environment around the ring network cabinet, conduct risk assessment in advance, and control the temperature and humidity adjustment device 5 to start and regulate the temperature and humidity inside the cabinet 1.

[0070] When the temperature and humidity inside cabinet 1 do not require adjustment, the external environment detection module 7 detects the ambient temperature M1 of the ring main unit and transmits the detection result to the central control system 10. The central control system 10 compares the ambient temperature M1 with a high temperature threshold Wz that is 1.1 times higher.

[0071] When M1 > 1.1Wz, the central control system 10 controls the temperature and humidity regulating device 5 to start, so as to pre-cool the inside of the ring main unit and ensure the operating temperature inside the ring main unit.

[0072] The external environment detection module 7 detects the ambient humidity D1 of the ring main unit and transmits the detection result to the central control system 10. The central control system 10 compares the ambient humidity D1 with a humidity threshold Sz of 1.1 times.

[0073] When D1 > 1.1Sz, the central control system 10 controls the temperature and humidity regulating device 5 to start, so as to dehumidify the inside of the ring main unit in advance and ensure the humidity of the ring main unit during operation.

[0074] When the temperature and humidity of the environment where the ring main unit is located are higher than the temperature and humidity thresholds for operation inside the ring main unit, the temperature and humidity of the environment will diffuse into the ring main unit. In order to ensure that the temperature and humidity inside the ring main unit are within a reasonable operating range, the temperature and humidity regulating device 5 is activated in advance to prevent the internal temperature and humidity from rising due to the diffusion of external temperature and humidity into the ring main unit. This preventive measure ensures that the internal temperature and humidity of the ring main unit are within a reasonable range, further guaranteeing the stability of the ring main unit during operation.

[0075] Specifically, the external environment detection module 7 detects the ambient temperature and humidity, and compares the ambient temperature and humidity with the temperature and humidity inside the cabinet 1, respectively, and adjusts the opening and closing of the heat dissipation holes based on the comparison results.

[0076] Specifically, when the ambient temperature is higher than the temperature inside the cabinet 1 and the ambient humidity is higher than the humidity inside the cabinet 1, the central control system 10 controls the ventilation hole 6 to close.

[0077] When the ambient temperature is lower than the temperature inside cabinet 1 and the ambient humidity is lower than the humidity inside cabinet 1, the central control system 10 controls the ventilation hole 6 to open.

[0078] When the ambient temperature is lower than the temperature inside the cabinet 1 and the ambient humidity is higher than the humidity inside the cabinet 1, or when the ambient temperature is higher than the temperature inside the cabinet 1 and the ambient humidity is lower than the humidity inside the cabinet 1, the central control system 10 determines the opening and closing of the ventilation hole 6 based on the temperature difference and humidity difference.

[0079] When the ambient temperature is lower than the temperature inside cabinet 1 and the ambient humidity is higher than the humidity inside cabinet 1, the central control system 10 calculates the difference between the ambient temperature and the temperature inside cabinet 1, ΔW1, and the difference between the ambient humidity and the humidity inside cabinet 1, ΔS1, where ΔW1 = W - M1 and ΔS1 = D - S1. The central control system 10 calculates the opening and closing score F1 of ventilation hole 6, F1 = ΔW1 × A1 - ΔS1 × B1, where A1 is the adjustment value calculated by the temperature difference ΔW1 on the opening and closing score of ventilation hole 6, and B1 is the adjustment value calculated by the humidity difference ΔS1 on the opening and closing score of ventilation hole 6. The calculated adjustment value can balance the dimensions on both sides of the formula.

[0080] When F1 > 0, the central control system 10 controls the ventilation vent 6 to open;

[0081] When F1≤0, the central control system 10 controls the ventilation hole 6 to close.

[0082] The opening and closing score calculation adjustment value B1 of ventilation hole 6 varies with the difference between humidity ΔS1. The larger the value of ΔS1, the larger the value of B1.

[0083] When the ambient temperature is higher than the temperature inside cabinet 1 and the ambient humidity is lower than the humidity inside cabinet 1, the central control system 10 calculates the difference between the ambient temperature and the temperature inside cabinet 1, ΔW2, and the difference between the ambient humidity and the humidity inside cabinet 1, ΔS2, where ΔW2 = M1 - W, ΔS2 = S1 - D. The central control system 10 calculates the opening and closing score F2 of ventilation hole 6, F2 = ΔW2 × A2 - ΔS2 × B2, where A2 is the adjustment value calculated by the temperature difference ΔW2 for the opening and closing score of ventilation hole 6, and B2 is the adjustment value calculated by the humidity difference ΔS2 for the opening and closing score of ventilation hole 6. The calculated adjustment value can balance the dimensions on both sides of the formula.

[0084] When F2 > 0, the central control system 10 controls the ventilation vent 6 to close;

[0085] When F2≤0, the central control system 10 controls the ventilation hole 6 to open.

[0086] The temperature difference △W2 affects the opening and closing score of ventilation hole 6. The adjustment value A2 changes with the temperature difference △W2. The larger the value of △W2, the larger the value of A2.

[0087] When the temperature and humidity of the environment where the ring main unit is located are higher than the temperature and humidity inside the ring main unit, the temperature and humidity of the environment will diffuse into the ring main unit. In order to ensure that the temperature and humidity inside the ring main unit are within a reasonable operating range, the opening and closing of the ventilation hole 6 is reasonably controlled to ensure the stability of the ring main unit during operation.

[0088] Specifically, when the temperature and humidity control device 5 is turned on to cool down the cabinet 1, the temperature detection device detects the temperature change curve inside the cabinet 1. When the temperature change curve is less than the preset expected temperature drop curve, the central control system 10 determines that the temperature inside the cabinet 1 is abnormally rising, and the central control system 10 sends abnormal information to the remote control center.

[0089] The central control system 10 is equipped with a timing system. When the temperature and humidity control device 5 is activated to cool the cabinet 1, the central control system 10 starts the timing function. When the timing duration reaches the preset duration T, the central control system 10 acquires the two endpoints of the temperature change curve inside the cabinet 1 and calculates the slope K between the two endpoints. The central control system 10 has a temperature drop reference slope Kz set within it. When the slope K is negative, the central control system 10 compares the slope K with the temperature drop reference slope Kz.

[0090] When K≤Kz, the central control system 10 determines that the temperature drop has reached the expected level;

[0091] When K > Kz, the central control system 10 determines that the temperature drop has not met expectations, and sends abnormal information to the remote control center.

[0092] When the slope K is positive, the central control system 10 directly sends abnormal information to the remote control center.

[0093] If the cooling requirement is not met when cooling the ring main unit, it indicates that the cabinet 1 is overheating abnormally. Therefore, by checking and analyzing the temperature drop curve, it is determined whether the cabinet 1 is overheating abnormally, so as to identify the problem in time and solve it as soon as possible to prevent damage to the power equipment caused by monitoring delays.

[0094] Specifically, the slope of the expected temperature decrease curve is related to the external temperature of cabinet 1.

[0095] Calculate the difference ΔM between the external temperature of cabinet 1 and the high-temperature threshold, ΔM = M1 - Wz. Calculate the median value of the temperature drop reference slope Kp, Kp = Kj + ΔM × k, where k is the compensation parameter for ΔM calculated on the temperature drop reference slope Kz, and Kj is the base value of the temperature drop reference slope Kz. The central control system 10 has a maximum temperature drop reference slope Km. The central control system 10 compares Kp with Km.

[0096] When Kp≤Km, Kp is selected as the value of the reference slope Kz for the temperature drop;

[0097] When Kp > Km, Km is selected as the value of the reference slope Kz for temperature decrease.

[0098] When the external temperature of cabinet 1 is higher than the high temperature threshold, the external temperature is not conducive to cooling inside cabinet 1, so the value of the temperature drop reference slope is increased at this time; when the external temperature of cabinet 1 is lower than the high temperature threshold, the external temperature is conducive to cooling inside cabinet 1, so the value of the temperature drop reference slope is decreased at this time; by adjusting the value of the temperature drop reference slope, the slope comparison is made more accurate.

[0099] Specifically, when the temperature and humidity control device 5 is used to cool the inside of the cabinet 1, the external environment detection module 7 collects the temperature outside the cabinet 1 at this time and compares the temperature outside the cabinet 1 with the high temperature threshold. When the temperature outside the cabinet 1 is higher than the high temperature threshold, the ventilation hole 6 is closed.

[0100] Specifically, the video detection module 8 can detect image information inside the cabinet 1. When a fire source appears inside the ring network cabinet, the fire prevention device 9 is activated to extinguish the fire source.

[0101] The technical solution of the present invention has been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the scope of protection of the present invention is obviously not limited to these specific embodiments. Without departing from the principles of the present invention, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the scope of protection of the present invention.
