Description

Remote control automatic inspection system used in thermal power plant

Technical Field

The utility model belongs to the technical field of automatic inspection, and relates to a remote control automatic inspection system used in a thermal power plant.

Background

Along with the industrial development, the industrial enterprise is increasingly large and modern, the structure and technology of production equipment are more complex, the functions of equipment implementation are expected to be fully exerted, the direct and indirect economic losses caused by equipment maintenance are reduced, and enterprises are required to carry out high-efficiency scientific inspection on the equipment. At present, the inspection of equipment facilities is only performed by simple file establishment and archiving after the equipment is purchased for the first time and manual tracking and recording.

At present, the traditional inspection mode mainly comprises the following steps:

Looking at: the binocular vision device is used for observing the visible part of the device, and observing the surface change of the visible part to find abnormal phenomena, such as the change of the paint color of the standard color device, the change and leakage of the color of bare metal, the oil color of the oil-filled device and the like, and the damage crack, pollution and the like of the device insulation.

Ear hearing: many devices in operation, whether stationary or rotating, can emit sounds indicative of their operating conditions. As the transformer operates normally, a steady, uniform and low "buzzing" sound is known, which is the result of frequent vibrations of the alternating magnetic field. The operator on duty can judge the operation condition of the electric equipment through the change of the height, rhythm and sound color and the strength of noise by the ears or by means of a listening device (such as a listening stick) when abnormal conditions occur as long as the operator is skilled in mastering the sound conditions of the equipment during normal operation.

Nasal sniffing: for the smell generated by overheat of the organic insulating material, once the operator on duty smells the burnt smell of the insulating burning loss in the inspection process, the operator should immediately find the detailed part of the heating element to identify the severity of the heating element, such as smoking, color change and presence or absence of abnormal sounds, thereby inspecting the situation.

In addition, the traditional inspection method must be performed on site and through paper records.

In summary, the existing inspection method has the following defects:

1. The prior art lacks tracking and linkage for equipment maintenance, inspection, monitoring and the like.

2. Relying on manual inspection has the problems of low operation efficiency, scattered operation, manual recording errors, difficulty in quick search and inquiry, difficulty in timely updating and tracking.

3. The large-scale equipment is provided with a plurality of sensors, the operation is very complex, the equipment cannot be comprehensively checked, the condition of missing detection is very easy to occur, and the large potential safety hazard exists.

Aiming at infrared thermal imaging temperature measurement inspection equipment in the thermal power industry, at present, a power plant video monitoring system can only realize functions of basic video preview, route playback and the like, and the utilization value of a large number of video recordings is not high, and the on-site intelligent level is not enough. With the continuous development of emerging technologies such as thermal imaging, video monitoring has been developed from high definition to intelligent. By newly building or modifying a power plant video monitoring system, intelligent applications such as power plant end face recognition, license plate recognition, intelligent meter reading, personnel behavior analysis, running and leakage monitoring, equipment temperature on-line monitoring, equipment operation fault monitoring, illegal operation behavior recognition and the like are realized, the traditional industrial television and security monitoring system can only realize that a special user is converted into data and alarm information which are directly labeled, structured and intelligent through video output, the value of the video monitoring system is fully excavated, and the safety management and production operation level of the power plant are improved.

The intelligent patrol is an important component of the construction of an intelligent power plant. Firstly, advanced technologies such as the Internet of things and artificial intelligence are required to be fully utilized, traditional manual inspection of a power plant is gradually replaced by an intelligent machine, personnel are relieved from high-strength and complicated inspection operation, and the power plant is helped to realize 'two improvements' of personnel reduction and synergy, inspection management and capability.

Secondly, an intelligent inspection system is needed, on-line remote inspection is taken as a main, off-line manual inspection is taken as an auxiliary, and an inspection business system design is carried out in combination with the actual condition of a power plant, so that re-optimization of an inspection management flow is promoted and perfected in continuous practical application. The AI is used for holding, so that the operation behaviors of power plant personnel are further standardized, potential safety hazards are prevented, and the business objective of lean management is achieved.

Finally, the intelligent inspection system has automation and intellectualization capability, and breaks through the limitation of the traditional manual inspection in management and technology. Through the inspection business closed loop, various problem defects can be found, corrected and solved early, and the power plant is digitally transformed and developed with high quality.

In the utility model, the inspection object of the infrared thermal imaging temperature measurement inspection equipment in the thermal power industry comprises a fuel system, a coal bunker, a fuel system, a belt, a combustion system, a generator carbon brush, a steam-water system, an air cooling island and an electric system, and the intelligent online inspection of a transformer substation.

Aiming at fire prevention and temperature measurement of a fuel system, namely a coal bunker, the coal bunker is an important fuel storage system of a thermal power plant and is generally in the types of a round coal bunker, a strip coal bunker, a cylindrical coal bunker and the like. If the environmental factors in the coal bunker are not properly controlled, such as temperature and humidity, air fluidity and the like, spontaneous combustion of the coal pile is easy to occur. Therefore, the coal bunker coal pile needs to measure temperature and prevent fire.

For the temperature measurement of a fuel system, namely a belt, the belt is used for carrying and transporting coal from a coal bunker to a boiler in a thermal power plant, and plays a key role in the production process. The accidents of the belt caused by fire do not occupy a small number, and the spontaneous combustion of raw materials and the friction of a carrier roller are all causes for igniting the belt. Therefore, the belt needs to be temperature-measured and fireproof.

Aiming at the temperature measurement of a carbon brush of a combustion system-a generator, the carbon brush and a collecting ring of the generator are one of important parts for normal power generation and current conduction of the generator, and the carbon brush and the collecting ring can well operate in the generator, so that the safe and stable operation of a generator set is directly influenced. Therefore, the carbon brush and the concentrated electric ring need to be subjected to temperature monitoring, and the normal operation of the generator is ensured.

Aiming at the temperature measurement of a steam-water system-an air cooling island, the air cooling island is a cooling technology of a thermal power plant for saving water, and the air and steam are subjected to heat exchange in a cooling mode of taking air instead of water as a cooling medium. Therefore, the air cooling island needs to be subjected to area array type temperature measurement, and the problem of freezing of the condenser tube bundle is intuitively found.

Aiming at the intelligent online inspection of an electrical system-a transformer substation, various electrical equipment in a power plant can generate certain heat during normal operation, and based on the reasons of the increase of the operation time of the equipment, unbalance of loads, rust and corrosion of certain joints, contact resistance increase caused by poor contact, overlarge current and the like, thermal state abnormality and overheat faults of the system, the equipment and a loop can be caused, and more and stronger infrared energy can be radiated at abnormal positions and fault points than in a normal state. The main monitoring objects mainly comprise power transmission and transformation equipment, a cable layer, a cable gallery, a power plant heating pipeline and the like. The infrared thermal imaging on-line temperature measurement diagnosis equipment adopts a non-contact on-line method to diagnose and measure the temperature distribution field and the change condition of the surface of the power equipment, thereby realizing non-contact on-line temperature measurement. Through on-line monitoring, the possible thermal state abnormal phenomenon of the electric equipment is found out, and potential fault points are found out, so that on-line fault diagnosis of the electric equipment is realized.

Aiming at the infrared thermal imaging temperature measurement inspection in the thermal power industry, the utility model provides thermal imaging equipment serving as a sensing device for thermal imaging acquisition. The thermal imaging device is a thermal imaging camera; the type of thermal imaging camera at least comprises a thermal imaging barrel machine, a thermal imaging ball machine, a thermal imaging hemisphere and a thermal imaging camera; the thermal imaging camera is fixed on the thermal imaging holder and/or the thermal imaging explosion-proof holder.

Corresponding to the fire prevention and temperature measurement of a fuel system, namely a coal bunker, spontaneous combustion of coal in the coal bunker is a ubiquitous phenomenon, the coal in the air continuously undergoes oxidation reaction, heat is emitted to the outside, and spontaneous combustion can occur once the heat is accumulated. The spontaneous combustion temperature of coal exceeds 350 ℃, and once spontaneous combustion occurs, great losses are caused to the coal, building structures and equipment of the whole coal bunker. Meanwhile, the calorific value of the coal after spontaneous combustion is lost, toxic gas is released, and the harm to the health and safety of field personnel is generated. There is a need for effective monitoring of spontaneous combustion of coal. The existing monitoring means for spontaneous combustion of coal are provided with temperature sensors and gas sensors, and if full coverage is realized on a large-scale coal bunker, a large number of sensors are needed, the requirements on construction distribution points are very high, and missing report and delay report are easy to occur.

In view of the above, in the embodiment of the present utility model, the selection of the thermal imaging explosion-proof equipment is first performed according to the scene explosion-proof requirement.

The thermal imaging device is a rotary device, and the shape of the ball machine or the cradle head can be selected according to the field installation condition. Each thermal imaging device carries out temperature measurement and inspection on the respective region, and the coverage radius of a single device is 50 meters (under the condition of ensuring the precision, the temperature is +/-2 ℃ or the reading is +/-2%). If the temperature measurement precision requirement is relaxed, the temperature measurement radius distance can be properly enlarged.

For the top of the circular coal bunker, a thermal imaging double-spectrum camera can be arranged on the circumference equal-dividing points to serve as thermal imaging equipment, as shown in fig. 2, 8 thermal imaging double-spectrum cameras are arranged at 8 equal-dividing points, and real-time detection and early warning of the temperature of coal piles in respective areas are realized.

For the strip-shaped coal bunker top, four thermal imaging double-spectrum cameras are arranged at four vertex angles at the strip-shaped coal bunker top to serve as thermal imaging equipment, the four vertex angles are used as circles, the covering radius of each thermal imaging double-spectrum camera is used as a radius to draw a circle, and if adjacent circles have intersection, and all the four circles cover the coal bunker area, only four thermal imaging double-spectrum cameras are arranged; if the adjacent circles are disjointed, a thermal imaging double-spectrum camera is arranged at a position which cannot be covered according to the actual coal bunker condition. As shown in fig. 3, when the strip length is 120 meters, the strip area of the top surface of the coal bunker is equally divided into four parts, and a thermal imaging double-spectrum camera is respectively arranged at the midpoint position of the first bisector and the third bisector, so that 6 thermal imaging double-spectrum cameras with the reference numbers of 11-16 are arranged in the scheme.

The thermal imaging non-contact remote temperature measurement function can detect the temperature in the coal temperature rising process, set an alarm threshold, and alarm once the temperature of a coal pile exceeds the alarm temperature, for example, the threshold is set at 80 ℃, so that spontaneous combustion of coal is prevented in advance.

Corresponding to the temperature measurement of the fuel system, namely the belt, a plurality of potential safety hazards exist in the process of conveying coal by the belt, such as belt friction caused by spontaneous combustion of the coal and excessive belt bearing. The spontaneous combustion of coal generates a large amount of heat, which ignites the belt if the ignition point is reached. The belt bears too much coal, increases the friction of belt and bearing roller, leads to the belt to generate heat, also can lead to the belt spontaneous combustion if friction is serious. Therefore, temperature monitoring of the belt in operation is required. At present, a manual inspection method is adopted for field inspection, the detection means does not have real-time performance, the phenomenon of omission is easy to occur, and the personnel field inspection has a certain risk.

In view of the above, in the embodiment of the present utility model, the selection of the thermal imaging explosion-proof equipment is performed according to the scene explosion-proof requirement. The thermal imaging device should be fixedly monitored to ensure the real-time performance of temperature measurement. Each thermal imaging device measures the temperature corresponding to 1 belt, the coverage distance of a single device is determined according to the focal length of a selected lens, the lens is 3mm-50mm, the range covers 5 meters-50 meters, and the site installation position and the project cost are required to be considered. Meanwhile, the belt conveying speed is less than 2.5 m/s, and the equipment side can ensure the accuracy of temperature measurement in the operation process. The equipment is arranged above the belt, and the pitching angle is adjusted according to the required temperature measuring distance.

According to the temperature measurement of the carbon brush of the generator, which corresponds to a combustion system, phenomena such as discharge, tremble, uneven abrasion, surface oil stain and the like easily occur between the carbon brush and the collecting ring in the running process of the generator, the carbon brush and the collecting ring are caused to generate heat locally, if the temperature exceeds a set value, the performance of an insulating material is deteriorated, the aging of insulation is accelerated, and arc light faults are caused. If the power generator cannot be found in time and manually intervened, the power generator is stopped and even one-time equipment damage accident can be caused. Domestic carbon brush fault accidents frequently occur, but an effective prevention means is not available.

The space reserved by the internal heat supply imaging temperature measuring equipment of the brush cover is smaller, and the equipment with larger volume and larger lens focal length cannot be installed in the scene. The miniaturized card machine is the best choice of the scene, the 90-degree field angle and the temperature measuring distance equipment above 10 centimeters, and can be well applied to the brush cover. During specific installation, 6-8 thermal imaging card machines can be designed in the brush cover, and the carbon brush part is fixedly irradiated by the bracket. The thermal imaging is used for monitoring the temperature of the carbon brush and the collector ring, displaying the temperature distribution condition, automatically capturing the highest temperature point, finding out the abnormal temperature point in advance, and monitoring the running condition of the carbon brush.

Corresponding to the temperature measurement of a steam-water system-an air cooling island, the condenser tube bundle of the air cooling system is in contact with the environment, so that the condenser tube bundle is extremely easily affected by the environment, the freezing of the condenser tube bundle is a problem easily occurring in cold seasons, and an intuitive, rapid and real-time detection means is needed to discover and locate the freezing abnormal point in time. The existing detection means is manual temperature gun inspection, does not have detection instantaneity and visibility, and cannot visually find the fault position. Meanwhile, the field inspection has potential safety hazards, particularly the temperature of the inspection in winter is low, and the field inspection is inconvenient.

The diameter of the condenser tube bundle is smaller, and equipment with thermal imaging resolution of 640 x 512 is recommended to be used, so that abnormal parts can be better resolved. The focal length of the lens is selected according to the actual installation conditions in the field, and the scene shown in fig. 4 is exemplified: the air cooling island is 86 m long and 48 m wide, and the installation distance of the equipment is 55 m. The full coverage of the air cooling island can be realized by adopting 2 barrel machine cross fixed-point irradiation with high thermal imaging resolution, a horizontal field angle of 41 degrees and a lens focal length of 15 mm. If the rotary thermal imaging temperature measuring ball machine is used, 1-2 cruising monitoring can also realize full coverage. The thermal imaging remote area array temperature measurement technology can measure the temperature of the air cooling island region at a distance of 50m, intuitively display the temperature distribution of the condenser tube bundle, quickly lock the frozen abnormal points of the tube bundle and improve the inspection efficiency of inspection personnel.

Corresponding to the intelligent online inspection of an electric system and a transformer substation, the heating fault of the electric equipment of the transformer substation is an important potential safety hazard in the electric system, has great harm, and needs to solve the heating problem of the electric equipment to ensure the safe and stable operation of the electric system. In addition, the heating fault of the electrical equipment is timely detected, and repair measures are timely taken for the heating fault to disappear in the initial stage, so that the power supply network can be ensured to run in a safe state for a long time, high-quality electric power can be further provided for customers, meanwhile, the maintenance and repair cost can be remarkably reduced, and the loss caused by sudden power failure is avoided. At present, operation and maintenance detection of traditional high transformer substation equipment is mostly stopped at manual handheld operation detection, and the handheld temperature measurement mode has the following defects: the on-line real-time intelligent diagnosis cannot be realized, the on-line real-time intelligent diagnosis is greatly influenced by artificial factors and environmental factors, the accuracy of temperature measurement time and position is difficult to meet the requirements, the accurate large data analysis cannot be realized, the requirements on the professional quality of operation and maintenance personnel are high, the recorded report needs to be manually arranged, and the on-line infrared thermal imaging equipment automatically generates.

Aiming at the condition of temperature measurement of a transformer substation, the method comprises the following conditions:

Diagnosis of hot spot faults outside the high-voltage electrical equipment, such as heating caused by poor contact of wire clamps, knife switches and the like; diagnosing faults of the internal diversion loop of the high-voltage electrical equipment, such as poor contact of a static contact, a static contact base and a middle contact in the circuit breaker and poor contact in the cable head;

Diagnosis of insulation faults inside high-voltage electrical equipment, such as integral wetting, insulation aging and partial discharge of CT, PT, capacitors and the like;

Diagnosing oil shortage faults of the oil immersed electrical equipment, such as external temperature change caused by the reduction of an oil level surface in a main transformer porcelain bushing;

Diagnosis of abnormal voltage distribution and increased leakage current faults, such as damp of lightning arresters, and local heating caused by increased leakage current.

To the condition of switch board temperature measurement, in the switch board of transformer substation, there are a lot of high tension switchgear, all need carry out the temperature measurement. Because the switch contacts are inside the cabinet, a small thermal imaging needs to be deployed inside the cabinet in order to achieve more accurate temperature measurement. The thermal imaging card machine that the scheme adopted minimum imaging distance 0.1m, angle of field: 90 degrees multiplied by 66.4 degrees, is suitable for the installation in a narrow space in a cabinet.

The point location deployment principle of equipment:

The temperature measurement target range of the 9mm lens is 1.2 m-10 m; the temperature measurement target range of the lens with the thickness of 10mm is 1-10 m; the temperature measurement target range of the 15mm lens is 3-16 m; the temperature measurement target range of the 25mm lens is 3-25 m; the temperature measurement target range of the 50mm lens is 10-100 m.

The diameter of the temperature measurement target is 10cm or more, when the target object is displayed on an image to exceed 5*5 or more pixel points, the temperature measurement error can be controlled to be +/-2 ℃ or +/-2% of the measuring range, and the two are maximum values.

When the point of the main transformer site is deployed, the appearance state, the oil level, the gear, the sleeve, the porcelain bottle, the oil leakage, the fan state and the like of the main transformer are monitored, the appearance state and the on/off state of the regional breaker, the disconnecting switch and the grounding disconnecting switch are monitored, and the appearance state of the regional pipe busbar (or busbar) and the contact state with the disconnecting switch are monitored.

The operation state of high-voltage chambers (switching chamber, capacitor chamber, used transformer chamber, arc suppression coil chamber) and the appearance state of the equipment in the transformer substation are monitored.

In the above-mentioned different scenarios, after the signals are collected by the thermal imaging device, the signals are transmitted to the CPU as the control mechanism 20, and after calculation and analysis, whether the faults occur or not is confirmed, and then transmitted to the inspection mechanism 30. The inspection mechanism 30 performs automatic inspection, and performs alarm or fault handling.

The infrared thermal imaging technology is a passive non-contact detection and identification technology, has the characteristics of long distance, no contact, no sampling, no contact and the like when the equipment state diagnosis is carried out, and has the characteristics of accuracy, rapidness, intuitiveness and the like, and most faults of the electrical equipment are monitored and diagnosed on line in real time. Thereby making the operator of the thermal imaging dual spectrum camera safer. The infrared thermal imaging technology is free from electromagnetic interference, and can accurately track a thermal target in a long distance.

The embodiment truly achieves 24-hour all-weather monitoring. Infrared radiation is the most widely known radiation in nature, and the atmosphere, clouds, etc. can absorb visible and near infrared, but is transparent to infrared of 8-14um, a wavelength band known as the "atmospheric window" of infrared. Therefore, by using the window, the monitored target can be clearly observed at night without light or in severe environments where clouds such as rain, snow and the like are densely distributed.

The device of the embodiment has strong detection capability and long acting distance. The thermal imaging dual spectrum camera is suitable for non-contact large area telemetry. And the temperature resolution is up to 50mk, the temperature measuring range is-50-550 ℃, the application field is wide, and the temperature measuring precision is up to +/-2 ℃.

Infrared thermal imaging technology can intuitively display the temperature field of the surface of an object. The thermal imaging double-spectrum camera not affected by strong light can measure the temperature of each point on the surface of an object at the same time, intuitively display the temperature field on the surface of the object and display the temperature field in an image form. Meanwhile, the thermal imaging double-spectrum camera is used for detecting the infrared thermal radiation energy of the target object and is not influenced by strong light. Multiple characteristics of smoke and fire are extracted by using a deep learning algorithm to learn and judge, so that scenes with different characteristics such as indoor, outdoor, equipment and environment can be self-adapted, and the alarm accuracy is improved. And along with the accumulation of scene materials, the system can continuously optimize and progress, and the recognition accuracy and the environment adaptability are improved.
