Technical Field

[0001] The present invention relates to the technical field of electric power equipment, and in particular to a comprehensive status monitoring device for an intelligent power station. Background Art

[0002] With the rapid development of smart grids, power stations are the core components of power systems, and the stability and reliability of their operating status are crucial to ensuring the safety and efficiency of power supply. There are many devices in power stations, including generators, transformers, switch cabinets and other key equipment. The operating status of these devices directly affects the overall performance of the power station. Therefore, comprehensive status monitoring of power stations and timely detection and handling of potential faults are of great significance to improving power station operation efficiency and reducing operation and maintenance costs.

[0003] However, traditional power plant status monitoring methods often rely on manual inspections and regular maintenance, which is not only inefficient but also difficult to achieve comprehensive and real-time monitoring of all equipment in the power plant. In addition, although there are some automated monitoring equipment on the market, they often have problems such as single monitoring parameters, insufficient data analysis capabilities, and low system integration, which cannot meet the high requirements of modern power plants for comprehensive status monitoring.

[0031] See also Figure 1-7 A comprehensive status monitoring device for an intelligent power station includes a plurality of electric cabinets 100 and an overhead slide rail 300, wherein a sliding member 500 is slidably connected to the overhead slide rail 300, and a camera assembly 510 and a gas sensor assembly 520 are arranged on the sliding member 500, wherein the camera assembly 510 includes an infrared thermometer and a visible light camera, and a turntable drive motor 511 is arranged on the sliding member 500, wherein the turntable drive motor 511 drives a turntable 512 to rotate, and a vertical plate 513 is arranged on the turntable 512, and a rotating drum 514 is rotatably connected to the vertical plate 513, and the rotation direction of the rotating drum 514 is perpendicular to the rotation direction of the turntable 512, and the camera assembly 510 is fixed on the rotating drum 514.

[0032] In an optional embodiment, each electric cabinet 100 is connected to a separate gas pipe 200, and the other end of each gas pipe 200 is connected to the same central pipe 400. The central pipe 400 is arranged on the side or in the middle of the overhead rail 300 and is parallel to the overhead rail 300. The sliding member 500 slides along the central pipe 400. The gas sensor assembly 520 is connected to a sliding ring 521. The cross-section of one end of the sliding ring 521 that is attached to the central pipe 400 is semi-annular. A hollow pipe is arranged in the sliding ring 521. The hollow pipe is used to connect the gas sensor assembly 520 with the central pipe 400. When the sliding member 500 slides to different positions, the temperature of different electric cabinets 100 is measured and photographed, and the gas in the electric cabinet 100 is transported to different areas in the central pipe 400 through the gas pipe 200, and then the gas in different areas is transported to the gas sensor assembly 520 through the sliding ring 521 for detection.

[0033] In an optional embodiment, the central pipe 400 is a hollow pipe, and a plurality of partitions 403 are arranged in the central pipe 400. The partitions 403 divide the central pipe 400 into a plurality of cavities. Each cavity in the central pipe 400 is symmetrically provided with an air inlet 401 and an air outlet 402 on two sides. The air inlet 401 on each cavity is connected to the corresponding gas pipe 200, and the air outlet 402 is used to transport the gas in the cavity to the gas sensor assembly 520 through the sliding ring 521 when the sliding ring 521 is fitted.

[0034] In an optional embodiment, the gas sensor assembly 520 is provided with an air suction assembly for sucking the gas in the cavity into the gas sensor assembly 520 for detection. The gas sensor assembly 520 is provided with a pressure sensor for detecting the air pressure in the gas sensor assembly 520. When the sliding ring 521 is not aligned with the air outlet 402, the air inlet end of the gas sensor assembly 520 is closed, and a negative pressure is formed under the action of the air suction assembly. When the sliding ring 521 is aligned with the air outlet 402, the pressure of the gas sucked by the gas sensor assembly 520 returns to normal. The pressure sensor can be used to determine whether the sliding ring 521 is aligned with the air outlet 402, thereby realizing the positioning function.

[0035] In an optional embodiment, the overhead slide rail 300 includes two symmetrical slide rails, which are fixedly connected by a plurality of connecting plates 301, and a support frame 302 is fixedly connected to the top of each connecting plate 301, and the other end of the support frame 302 is fixed to a wall or a roof.

[0036] In an optional embodiment, a power device 310 is further provided on the overhead slide rail 300, and the power device 310 includes a cable 311.

A driving wheel 312 and a driven wheel 313 are respectively provided at both ends of the central pipe 400 for driving the cable 311 to slide, thereby driving the sliding member 500 to slide.

[0037] In an optional embodiment, a control box 502 is fixed on the gas pipe 200, and a processor and a power supply are provided in the control box 502. The processor is used to control the camera component 510 and the gas sensor component 520 to perform detection, and transmit the detected data to the terminal through a wireless transmission module. An alarm device is provided in the terminal to sound an alarm when the data is abnormal.

[0038] In an optional embodiment, the gas to be detected in the gas sensor assembly 520 includes combustible gases, such as hydrogen, methane, etc. In the battery room of some hydropower stations, hydrogen may be generated during the battery charging process. Hydrogen is a highly flammable gas that can form an explosive mixture when mixed with air. When the hydrogen concentration reaches a certain ratio of its lower explosion limit (the lower explosion limit of hydrogen is 4.0%), for example 20%, the gas detection alarm device will alarm.

[0039] In an optional embodiment, the gas to be detected in the gas sensor assembly 520 includes combustible gases, such as carbon monoxide, sulfur dioxide, etc. Near the boiler room of a thermal power station, coal combustion may produce a small amount of sulfur dioxide. When the sulfur dioxide concentration exceeds the occupational exposure limit of 10 mg / m³ for a short time, the alarm device will sound an alarm to prevent people from poisoning.

[0040] In an optional embodiment, the gas to be detected in the gas sensor assembly 520 includes insulating gas, mainly sulfur hexafluoride SF6 gas. In the gas insulated switchgear GIS of the substation, SF6 gas is widely used for its excellent insulation and arc extinguishing properties. When the SF6 gas leakage rate reaches a certain level, for example, the annual leakage rate exceeds 1%, the gas detection alarm device will detect it and alarm.

[0041] In an optional embodiment, the gas sensor assembly 520 includes: Catalytic combustion sensor is used to detect combustible gas. Its principle is that combustible gas burns flamelessly under the action of catalyst. The heat generated by combustion increases the temperature of the sensor, which in turn causes the resistance of the sensor to change. The concentration of combustible gas can be determined by measuring the change in resistance. Electrochemical sensors are mainly used to detect toxic gases. They are based on the principle of electrochemistry. When toxic gases enter the electrolyte of the sensor, an electrochemical reaction will occur. For example, in a carbon monoxide electrochemical sensor, carbon monoxide reacts with the electrolyte on the electrode surface of the sensor to generate a current. The current is proportional to the concentration of carbon monoxide. The concentration of carbon monoxide can be determined by detecting the current. Infrared absorption sensors are more effective for gas detection in some complex environments, especially for gases such as SF6. The principle is that different gas molecules absorb infrared light of specific wavelengths. Taking SF6 gas as an example, when infrared light passes through an area containing SF6 gas, SF6 molecules absorb infrared light of specific wavelengths. The concentration of SF6 is determined by detecting changes in the intensity of infrared light.

[0042] In an optional embodiment, the electric cabinet 100 is provided with air inlets and outlets, the air inlet 101 is provided at the bottom of the side wall of the electric cabinet 100, the air outlet is provided on the top cover of the electric cabinet 100 or the top of the side wall, the air outlet is connected to the gas pipe 200, and the electric cabinet 100 is provided with an air suction device 201 between the air outlet and the gas pipe 200, and the air suction device 201 can be used to ventilate the electric cabinet 100 while transporting the gas in the electric cabinet 100 to the central pipeline 400.

[0043] In an optional embodiment, the electrical cabinet 100 includes a back plate, two side walls, a front door, a top cover and a bottom plate, wherein the side walls and the front door are made of transparent material to facilitate shooting by the camera assembly 510 .

[0044] In an optional embodiment, a vibration sensor is further disposed in the electrical cabinet 100 .

[0045] In summary, the intelligent power station comprehensive status monitoring device, by setting an overhead slide rail 300 in the power station, the sliding member 500 slides on the overhead slide rail 300 so that the gas sensor component 520 performs infrared temperature detection and high-definition image shooting on the electric cabinets 100 in different areas. At the same time, the gas sensor component 520 set on the sliding member 500 can detect the gas composition in different areas as the sliding member 500 moves. Compared with stationary gas detection, the gas sensor component 520 has the advantage of accurate detection.

[0046] The intelligent power station comprehensive status monitoring device is connected to the gas pipe 200 at the gas outlet position of the electric cabinet 100, and the other end of the gas pipe 200 is connected to the central pipe 400. The camera component 510 on the gas sensor component 520 fits the central pipe 400 during the sliding process, and the gas outlet 402 of the central pipe 400 is connected to the gas sensor component 520 through a sliding ring 521. The gas in multiple cavities separated by partitions 403 in the central pipe 400 is sucked into the gas sensor component 520 for detection through the suction component, and whether there is an abnormality in each electric cabinet 100 can be judged by analyzing the gas components.

[0047] The intelligent power station comprehensive status monitoring device is used to monitor the air pressure in the gas sensor assembly 520 by arranging a pressure sensor in the gas sensor assembly 520. When the sliding collar 521 is not aligned with the air outlet 402, the air inlet end of the gas sensor assembly 520 is closed, and negative pressure is formed under the action of the air suction assembly. When the sliding collar 521 is aligned with the air outlet 402, the pressure of the gas inhaled by the gas sensor assembly 520 returns to normal. The pressure sensor can be used to determine whether the sliding collar 521 is aligned with the air outlet 402, thereby realizing the positioning function.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
