Description

Technical Field

[0001] This invention belongs to the field of high-voltage switchgear environmental management technology, and particularly relates to a power environment intelligent management and early warning system and method, and more specifically, a high-voltage switchgear operating environment intelligent management and early warning system and method. Background Technology

[0002] Currently, high-voltage switchgear is susceptible to changes in external temperature and humidity during operation, which can easily lead to condensation, temperature rise, and accumulation of electrostatic dust inside the cabinet. Traditional control methods are mostly passive protection, such as adding ordinary fans and dehumidifying bags, which have problems such as low control precision, inability to adjust in real time, and lack of early warning of environmental anomalies. This can easily lead to a decrease in the insulation performance of the switchgear, excessive temperature rise of the equipment, safety failures, and affect the stable operation of the power system.

[0003] The existing technologies mentioned above cannot achieve intelligent analysis, precise control, and multi-dimensional risk monitoring of the environment inside the cabinet. Therefore, there is an urgent need to develop an integrated and intelligent governance and early warning system to solve the above-mentioned deficiencies. Summary of the Invention

[0004] To address the shortcomings of the existing technologies, this invention provides an intelligent power environment management and early warning system and method. Its purpose is to solve problems such as condensation, electrostatic dust accumulation, excessive temperature rise, and lack of effective early warning in the operating environment of high-voltage switchgear, providing an intelligent management and early warning system for the operating environment of high-voltage switchgear that can collect environmental parameters in real time, intelligently regulate the operating environment, and expand to multi-dimensional monitoring functions.

[0005] The technical solution adopted by the present invention to achieve the above objectives is as follows: A method for intelligent management and early warning of dynamic environment includes the following steps: Obtain air environment parameters inside and outside the switchgear; The intelligent control and analysis system determines whether to activate the condenser for dehumidification and adjust the airflow. If so, the intelligent circulation host system receives the dehumidification command from the intelligent control and analysis system and activates the condenser to dehumidify and cool the filtered air. The intelligent control and analysis system also determines whether the air temperature is 2-3°C higher than the ambient temperature outside the cabinet. If so, air meeting the condition of being 2-3°C higher than the ambient temperature outside the cabinet flows into the air intake duct system. If not, the air is heated by heating wires to make the air temperature 2-3°C higher than the ambient temperature outside the cabinet. The air inlet duct valves are controlled according to the air supply volume to ensure that the required air passes through the air inlet duct system as needed. Air that meets the requirement of being 2-3℃ higher than the ambient temperature flows into the switch cabinet through the air intake duct system.

[0006] Furthermore, the air environment parameters inside and outside the switch cabinet include temperature and humidity data.

[0007] Furthermore, the air that meets the condition of being 2-3℃ higher than the ambient temperature flows into the switch cabinet through the air intake duct system. When the operation of the switch cabinet equipment affects the environment inside the cabinet, causing problems such as dust, high temperature, and condensation in the air, the air inside the switch cabinet flows into the intelligent circulation host through the return air duct system. The intelligent circulation host system filters the air flowing into the switch cabinet, and at this time, the condenser is started to dehumidify and cool the filtered air.

[0008] A dynamic environment intelligent management and early warning system includes an intelligent control and analysis system, an intelligent circulation host system, and a circulation wind power duct system. The intelligent control and analysis system is electrically connected to the intelligent circulation host system and the circulation wind power duct system respectively to realize data interaction and linkage control. The intelligent control and analysis system determines whether to activate the condenser for dehumidification and adjust the airflow. If so, the intelligent circulation host system receives the dehumidification command from the intelligent control and analysis system and activates the condenser to dehumidify and cool the filtered air. The intelligent control and analysis system also determines whether the air temperature is 2-3°C higher than the ambient temperature outside the cabinet. If so, air meeting the condition of being 2-3°C higher than the ambient temperature outside the cabinet flows into the air intake duct system. If not, the air is heated by heating wires to make the air temperature 2-3°C higher than the ambient temperature outside the cabinet. The intelligent circulation host system is used to control the air valves in the air inlet duct according to the air supply volume, so that the required air passes through the air inlet duct system as needed; The circulating air duct system is used to bring air that meets the requirement of being 2-3°C higher than the ambient temperature into the switch cabinet through the air intake duct system.

[0009] Furthermore, the system also includes a partial discharge monitoring module, a pyroelectric particle monitoring module, and a wireless temperature measurement module. Each module is electrically connected to the intelligent control and analysis system to achieve data interaction and linkage control. The partial discharge monitoring module is installed inside the switch cabinet using a magnetic method through a partial discharge monitoring sensor. It achieves intelligent partial discharge interference filtering and intelligent algorithm identification of suspected partial discharge through an intelligent monitoring host. It outputs the current partial discharge intensity value and identifies suspected partial discharge risks in real time. When combined with the intelligent monitoring platform for electrical equipment, it can realize spectrum output, long-term operation trend analysis, AI trend analysis, and intelligent alarm. The pyroelectric particle monitoring module uses particle detection technology. A pyroelectric ion detection device is installed at the main return air vent of each switchgear cable compartment to detect pyroelectric ions released after materials are damaged by heat. The collected signals are connected to the control system. When the number reaches the set threshold, the switchgear fire risk assessment is performed quickly and accurately and an early warning is issued. The wireless temperature measurement module's wireless temperature measurement function involves fixing a wireless sensor to the moving and stationary contacts, busbars, and cable joints inside the switch cabinet. The wireless temperature sensor then transmits the collected temperature signal to an intelligent wireless temperature measurement device via a wireless network to monitor temperature changes in real time.

[0010] Furthermore, the intelligent control and analysis system is equipped with temperature and humidity sensors for collecting temperature and humidity parameters inside and outside the switch cabinet; the intelligent control and analysis system receives monitoring data from the partial discharge monitoring module, the pyroelectric particle monitoring module, and the wireless temperature measurement module. By analyzing temperature and humidity data, the intelligent circulation host system filters, dehumidifies, and controls the temperature of the air, and controls the electric air valve to adjust the air supply volume, so as to achieve constant temperature and humidity in the switch cabinet. When the data exceeds the preset threshold, an alarm signal is triggered.

[0011] Furthermore, the intelligent circulating host system consists of a power supply box, compressor, fan, water pump, air supply outlet, air return outlet, filter, condenser, and water collection tray. It is connected to the return air duct of the circulating air duct system and receives control commands from the intelligent control and analysis system. The air returns from the return air outlet, is purified by the filter, cooled and dehumidified by the condenser, and pressurized by the fan before entering the air supply outlet. The heat pump is connected to the condenser to cool it, and the heat pump is also connected to the enclosure for heat dissipation. The power supply box supplies power to all electrical equipment via power lines.

[0012] Furthermore, the circulating air duct system includes a return air duct, an intake air duct, a temperature and humidity sensor, and electrically operated air valves deployed in each switch cabinet compartment. The electrically operated air valves are electrically connected to the intelligent control and analysis system, and adjust their opening degree according to the control strategy to control the air supply volume of each compartment. The intake air duct receives clean air output from the intelligent circulating host system and delivers the air to the inside of the switch cabinet through the air outlet and the electrically operated air valve, thereby realizing air circulation and environmental regulation inside the cabinet.

Specifically, it is a high-voltage switchgear power environment intelligent management and early warning system that can collect environmental parameters in real time, intelligently regulate the operating environment, and expand multi-dimensional monitoring functions. Combining IoT sensors and intelligent control technology, this high-voltage switchgear power environment intelligent management and early warning system fundamentally solves various safety hazards caused by condensation, electrostatic dust, and temperature rise in switchgear equipment, avoids switchgear equipment failures caused by environmental factors, and thus improves the stability and reliability of substation equipment safe operation.

[0016] This invention adds a dust filter, a partial discharge detection module, a wireless temperature measurement and detection module, a particle detection module, and a new control algorithm, enabling it to perform dust removal, partial discharge alarm, contact temperature detection, and fire alarm. The algorithm optimizes the overall control of the machine, further improving the environmental management and early warning effects compared to existing technologies, and adding functions such as dust removal, partial discharge detection, contact temperature detection, and fire alarm.

[0017] This invention achieves constant temperature and humidity control within the switchgear by linking an intelligent control and analysis system with the circulating host and air ducts. This keeps the temperature slightly higher than the ambient temperature by 2-3°C, preventing condensation from the source. At the same time, it removes electrostatic dust from inside the cabinet, reduces equipment temperature rise, and improves the operational safety and lifespan of the switchgear.

[0018] This invention supports the on-demand addition of partial discharge, pyroelectric particle and wireless temperature measurement functions to achieve multi-dimensional risk monitoring and anomaly early warning, avoid potential faults in advance, and adapt to the operation and maintenance needs of different scenarios.

Figure 2 This is an overall block diagram of the environmental management of the high-voltage switchgear group of the present invention; Figure 3 This is a flowchart of the environmental management method for high-voltage switchgear groups according to the present invention. Detailed Implementation

[0021] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments of the present invention and the features thereof can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.

[0023] The following reference Figures 1-3 The technical solutions of some embodiments of the present invention are described below.

[0024] Example 1

[0025] This invention provides an embodiment of a power environment intelligent management and early warning system, specifically relating to a high-voltage switchgear power operation environment intelligent management and early warning system and method. For example... Figures 1-2 As shown, Figure 1 This invention relates to an environmental management ventilation circulation and control diagram for high-voltage switchgear units. Figure 2 This is an overall block diagram of the environmental management of the high-voltage switchgear group of the present invention.

[0026] This invention discloses an intelligent power environment management and early warning system, comprising three parts: an intelligent control and analysis system, an intelligent circulation host system, and a circulating air duct system. The invention can selectively add partial discharge monitoring modules, pyroelectric particle monitoring modules, and wireless temperature measurement modules as needed. Each module is electrically connected to the intelligent control and analysis system to achieve data interaction and coordinated control.

[0027] The intelligent control and analysis system is electrically connected to the intelligent circulation host system, the circulating air duct system, the partial discharge monitoring module, the pyroelectric particle monitoring module, and the wireless temperature measurement module. The intelligent control and analysis system is equipped with temperature and humidity sensors for collecting temperature and humidity parameters inside and outside the switch cabinet. The intelligent circulation host system is equipped with a filter, condenser, compressor, and water collection tray. The circulating air duct system includes a return air duct, an inlet air duct, and an electric air valve. The intelligent control and analysis system analyzes the temperature and humidity data, controls the intelligent circulation host system to filter, dehumidify, and control the temperature of the air, and controls the electric air valve to adjust the air supply volume to achieve constant temperature and humidity inside the switch cabinet.

[0028] The intelligent control and analysis system receives monitoring data from the partial discharge monitoring module, the pyroelectric particle monitoring module, and the wireless temperature measurement module. When the data exceeds a preset threshold, it triggers an early warning signal. Specifically, the intelligent control and analysis system collects real-time air environment parameters inside and outside the switchgear using temperature and humidity sensors. It intelligently analyzes the air temperature and humidity data to generate control strategies for the main unit and air valves. The main unit directs air from the return air duct into the system through the return air inlet. First, the air passes through a filter to remove dust and other impurities. The purified air then undergoes condensation in the evaporator, releasing moisture into the condensate trap before being discharged from the system. The condensed air temperature drops significantly. At this point, a heater generates clean air slightly warmer than the ambient temperature (2-3°C) before it is sent to the supply air duct. The main unit releases moisture from the unpurified air into the condensate trap before discharging it from the system. Simultaneously, the system controls the electric air valves to adjust the airflow to each switchgear compartment, delivering the air to the switchgear interior through the supply air duct. This ultimately achieves a constant temperature and humidity environment inside the switchgear, preventing condensation, eliminating static dust, reducing temperature rise, effectively managing the operating environment, improving the safety and stability of the switchgear equipment, and extending its service life.

[0029] A power environment intelligent management and early warning system also includes temperature and humidity sensors, which are deployed inside and outside the switch cabinet to collect real-time air temperature and humidity parameters. The system has a built-in control algorithm to intelligently analyze the collected temperature and humidity data and generate start-up and shutdown and operation parameter control strategies for the intelligent circulation host system and opening adjustment strategies for the air valves in the circulation air duct system. It also receives monitoring data from partial discharge monitoring, pyroelectric particle monitoring, and wireless temperature measurement modules, and triggers an early warning signal when the data exceeds a preset threshold.

[0030] The intelligent circulating air handling unit system consists of a power supply box, compressor, condenser, fan, water pump, air supply outlet, return air outlet, and filter. It connects to the return air duct of the circulating air duct system and receives control commands from the intelligent control and analysis system. Internally, the system contains a filter, condenser, compressor, and water collection tray. During operation, air from the return air duct flows into the unit system through the return air outlet. It is first purified by the filter to remove dust and other impurities. The purified air then flows through the condenser, where moisture is separated and drips into the water collection tray and discharged from the system. The condensed, low-temperature air is then heated (if necessary) by a heater to generate clean air 2-3°C higher than the ambient temperature, which is then delivered to the air supply duct of the circulating air duct system. Analysis and practice have shown that a slightly higher air temperature (2-3°C) than the ambient temperature delivered to the switchgear effectively prevents condensation inside the switchgear. The intelligent circulating air handling unit system is the main working equipment for maintaining a constant temperature and humidity environment inside the switchgear, preventing condensation, and removing electrostatic dust. The intelligent circulating host system receives air from the return air duct, filters impurities through a filter screen, condenses and separates moisture through a condenser, discharges the moisture from the water collection tray, and then heats the air to 2-3°C higher than the ambient temperature before delivering it to the air intake duct.

[0031] The intelligent circulating air system is designed so that air returns from the return air vent, is purified by a filter, cooled and dehumidified by a condenser, and then pressurized by a fan before entering the supply air vent. The heat pump is connected to the condenser to cool it, and also connects to the enclosure for heat dissipation. The power supply box provides power to all the necessary equipment via power cords.

[0032] The circulating air duct system includes return air ducts, intake air ducts, temperature and humidity sensors, and electrically operated dampers deployed in each switchgear compartment. It is an important component of the fully enclosed closed-loop operation mode of the intelligent management and early warning system for the high-voltage switchgear operating environment. The electrically operated dampers are electrically connected to the intelligent control and analysis system, adjusting their opening degree according to the control strategy to control the air supply volume in each compartment. The intake air ducts receive clean air output from the intelligent circulating host system and deliver the air to the inside of the switchgear through the air outlets and electrically operated dampers, realizing air circulation and environmental regulation within the switchgear.

[0033] The specific system deployment is as follows: A 10kV high-voltage switchgear group was selected as the application object. One set of ambient temperature and humidity sensors was installed on the outside of the switchgear housing of each group of switchgear, and one set of internal temperature and humidity sensors was installed on the main return air duct of each switchgear. The intelligent circulation host system was deployed on a suitable wall outside the switchgear. The air inlet and return air ducts were set on the top of the switchgear group. One electric air valve was installed on the main duct of each switchgear. The branches of the air inlet and return air ducts extended to each switchgear interval and were connected to the inside of the cabinet through the opening of the pressure relief plate. A partial discharge monitoring module was added to the switchgear busbar compartment, a pyroelectric particle monitoring module was added to the main return air duct, and a wireless temperature sensor was installed at the power supply circuit joint.

[0034] Example 2

[0035] This invention provides another embodiment, which is an intelligent management and early warning system for the operating environment of high-voltage switchgear. In addition to the system components of the equipment in Embodiment 1, this invention can also selectively add a partial discharge monitoring module, a pyroelectric particle monitoring module, and a wireless temperature measurement module as needed.

[0036] In practical implementation, the system of this invention adds equipment with three functions: partial discharge monitoring, pyroelectric particle monitoring, and wireless temperature measurement. The intelligent control and analysis system uses the real-time data collection of the three sensors to determine whether the operating environment inside the switch cabinet is safe. If there are problems such as partial discharge, overheating of air temperature, or abnormal contact temperature, the intelligent control and analysis system will issue an alarm to prompt the operators to carry out maintenance.

[0037] The partial discharge monitoring module utilizes a magnetically mounted partial discharge monitoring sensor installed inside the switchgear. Partial discharge typically occurs more frequently in busbar compartments, hence its placement there. The intelligent monitoring host enables intelligent partial discharge interference filtering and intelligent algorithm identification of suspected partial discharge. It can output the current partial discharge intensity value and identify suspected partial discharge risks in real time (AI-powered automatic intelligent analysis). Combined with an intelligent electrical equipment monitoring platform, it can provide graph output, long-term operational trend analysis, AI trend analysis, and intelligent alarms, significantly reducing reliance on professional partial discharge technicians. This helps users detect equipment insulation degradation trends and potential hazards early, improving power supply reliability and quality.

[0038] The pyroelectric particle monitoring module employs particle detection technology. A pyroelectric ion detection device is installed at the main return air vent of each switchgear cable compartment. This device detects pyroelectric ions released when materials are damaged by heat, and collects the signals for input to the control system. When the number reaches a set threshold, it can quickly and accurately assess the switchgear fire risk and issue an early warning, giving power supply management departments more time to address equipment anomalies and potential faults, reducing the risk of major accidents such as power outages and fires. This particle detection device has higher accuracy, capable of detecting particles in the 10-100nm range (compared to the accuracy of ordinary smoke detectors greater than 300nm), and can provide early warnings several hours in advance.

[0039] The wireless temperature measurement module has the function of fixing wireless sensors to moving and stationary contacts, busbars, cable joints and other parts in the switch cabinet. The temperature signals collected by the wireless temperature sensors are sent to the intelligent wireless temperature measurement device through a wireless network to monitor temperature changes in real time, so as to prevent the contacts, cable joints and other parts from overheating and burning out, thereby causing a power outage.

[0040] Everything else is the same as in Example 1.

[0041] Example 3

[0042] This invention provides another embodiment, which is a method for intelligent management and early warning of the dynamic environment, implemented using the intelligent management and early warning system for the dynamic environment described in Embodiment 1 or 2. Figure 3 As shown, Figure 3 This is a flowchart of the environmental management method for high-voltage switchgear groups according to the present invention.

[0043] This invention includes the following steps: Step 1. The operation of the switchgear equipment affects the environment inside the cabinet, causing problems such as dust, high temperature, and condensation in the air. The air inside the switchgear flows into the intelligent circulation host through the return air duct system, and the intelligent circulation host system automatically filters the air flowing into the switchgear.

[0044] Step 2. The intelligent control and analysis system acquires indoor and outdoor air environmental parameters, including temperature and humidity data, through the acquisition equipment; Step 3. The intelligent control and analysis system combines the collected temperature and humidity data to analyze and determine whether to start the condenser. If so, the intelligent circulation host system receives the dehumidification command from the intelligent control and analysis system and starts the condenser to dehumidify and cool the filtered air. If not, the filtered air passes through directly without starting the condenser.

[0045] The intelligent control and analysis system determines whether the air temperature is 2-3℃ higher than the ambient temperature outside the cabinet. If so, the air that meets the condition flows directly into the air intake duct system. If not, the air is heated by heating wires to make the air temperature 2-3℃ higher than the ambient temperature outside the cabinet before flowing into the air intake duct system. Step 4. Control the air valve in the air inlet duct according to the required air supply volume, so that the required air passes through the air inlet duct system as needed; Step 5. Air that meets the condition of being 2-3℃ higher than the ambient temperature flows into the switch cabinet through the air intake duct system; Step 6. The above steps ensure that the switchgear can operate in a dust-free environment with moderate temperature and humidity. However, the switchgear continues to affect the environment during operation, so steps 1-5 are executed again, and so on, thus realizing intelligent management and early warning of the power operating environment of the high-voltage switchgear.
