Photovoltaic power plants are exposed to complex outdoor environments for a long time, and are affected by multiple factors such as high temperature, wind and rain, sand and dust, aging, and construction defects. Hidden dangers such as hot spots on photovoltaic modules, overheating of cable joints, abnormal heat dissipation of inverters, and excessive temperature in combiner boxes occur frequently. This type of hidden thermal fault has the characteristics of strong concealment, small initial temperature difference, and fast diffusion speed. If it cannot be promptly investigated and disposed of, it will not only cause the continuous decline of power generation and reduce power generation revenue, but also easily lead to safety accidents such as short circuits and fires, threatening the operation safety of the power station. Traditional temperature measuring equipment has low temperature measurement accuracy, blurry imaging, and poor ability to recognize subtle temperature differences, making it difficult to meet the requirements of refined inspection. To this end, Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has launched the LX-F200 handheld infrared thermal imaging device, which is a precise tool for identifying thermal hazards in photovoltaic power plants with the advantages of ultra-high temperature sensitivity, high-definition imaging, global adaptability, and portable intelligence. Compact, portable, precise imaging

The LX-F200 core temperature measurement imaging performance is industry-leading, equipped with an imported high-sensitivity uncooled infrared focal plane detector, using a 12 μ m advanced process technology, with a response band covering the 7 μ m-14 μ m long wave infrared range, perfectly suitable for outdoor photovoltaic equipment temperature measurement scenarios. The device has a thermal sensitivity of up to 50mK, which can accurately capture small temperature differences as low as 0.05 ℃. It can clearly distinguish between normal heating and abnormal heating caused by faults, completely solving the problem of small heat spots and hidden dangers caused by insufficient sensitivity in traditional equipment. The infrared resolution reaches 320 × 240 high-definition pixels, combined with 5 million visible light pixels and dual imaging support, which can clearly present the surface temperature distribution details of photovoltaic modules, cables, and electrical equipment. The thermal fault points are accurately located, and the imaging is clear and intuitive, making all kinds of hidden thermal hazards exposed.

The temperature measurement range and precise control capability are fully adapted to the needs of all scenario operations. The standard temperature measurement range of the equipment covers -20 ℃ to 650 ℃, and the wide temperature range design can perfectly adapt to various working conditions such as winter low-temperature inspection, summer high-temperature operation and maintenance, and equipment high-temperature fault diagnosis. It fully covers the temperature measurement and detection needs of photovoltaic supporting facilities such as photovoltaic modules, combiner boxes, inverters, distribution cabinets, cable joints, and bracket electrical equipment. The temperature measurement accuracy of the whole machine is strictly controlled within ± 2 ℃, and it is equipped with an intelligent temperature difference calculation program that supports custom environmental reference temperature. It can automatically calculate the temperature rise value and inter phase temperature difference of the measured point, effectively avoiding external factors such as temperature fluctuations, light, water vapor, sand and dust interference, and ensuring the accuracy and stability of temperature measurement data in complex outdoor scenes.

The device is equipped with multiple intelligent temperature measurement functions, greatly improving the level of intelligent inspection. Support full screen temperature rise display, fixed-point temperature measurement, automatic capture of the highest/lowest temperature in the area, temperature difference comparison analysis and other functions. It can quickly lock the abnormal heating area, automatically mark the fault location, without the need for manual repeated calculation and comparison, greatly improving the efficiency of fault diagnosis. In response to the demand for batch inspection of photovoltaic power plants, the equipment is equipped with a large capacity built-in storage space, which can store a massive amount of thermal imaging images, temperature measurement data, and inspection records. It supports access and viewing at any time, historical data comparison, and facilitates staff to track the temperature change trend of the equipment, achieving early detection, early warning, and early disposal of hidden dangers. Simultaneously supporting USB OTG wired transmission and WIFI wireless bidirectional transmission, it can quickly upload on-site detection data and high-definition thermal imaging images to terminal devices, facilitating data archiving, report generation, and remote analysis.

Humanized and lightweight design, suitable for outdoor long-term high-intensity inspection operations. LX-F200 strictly follows the ergonomic design concept, with a total weight of only 0.9kg. The body is compact and comfortable to hold, and can easily complete a full set of operations such as holding, focusing, shooting, and storage with one hand. It is not easy to fatigue during long-term outdoor inspections, high-altitude operations, and large-scale inspections, effectively reducing the workload of workers. The device is equipped with a 3.5-inch high-definition high brightness touch display screen and adopts strong light visualization technology. Even in the environment of direct sunlight at noon in summer, the imaging image and data display are still clear and visible, completely solving the problem of unclear screens in outdoor strong light and ensuring all-weather operation experience.

The equipment has strong protective performance and is suitable for various complex and harsh outdoor working conditions. The body is made of high-strength engineering plastic material, which has professional dustproof, waterproof, anti-seismic, and anti drop characteristics. It can effectively resist equipment damage caused by outdoor dust, rain, bumps, and slight collisions. It can operate stably in harsh environments such as high temperature, humidity, sandstorms, and severe cold. The stability and service life of the equipment far exceed that of ordinary civilian temperature measuring equipment. In terms of battery life, the device is equipped with a high-capacity long-lasting lithium battery, which can achieve continuous uninterrupted operation for more than 6 hours on a single full charge, fully meeting the battery life requirements of large-scale photovoltaic power plants for batch inspections and multi-point inspections throughout the day, without the need for frequent charging midway, effectively improving the continuity and efficiency of inspection operations.

In practical application scenarios, LX-F200 can accurately detect component faults such as local hot spots, aging and heating of solar cells, shading and heating, and virtual welding of photovoltaic modules. At the same time, it can efficiently detect electrical hazards such as oxidation and virtual connections of cable joints, overload heating of combiner boxes, poor heat dissipation of inverters, and abnormal temperature of distribution cabinet lines. It comprehensively covers daily inspections, quarterly inspections, annual acceptance, and fault repair scenarios of photovoltaic power plants. With its comprehensive advantages of precision, efficiency, convenience, and durability, this equipment effectively helps the power station operation and maintenance team reduce the failure rate, minimize power generation losses, avoid safety accidents, and greatly improve the intelligent and refined level of photovoltaic power station operation and maintenance.

As a specialized intelligent temperature measurement device for photovoltaic inspection, the LX-F200 handheld infrared thermal imaging instrument, with its hardcore performance configuration and scene based design, accurately meets the operational needs of the photovoltaic industry. In the future, LAILX in Suzhou will continue to deepen its cultivation in the field of intelligent detection of new energy, continuously optimize equipment temperature measurement algorithms and hardware configurations, and launch more intelligent detection equipment that is suitable for industry scenarios, to safeguard the safe, stable, and efficient operation of photovoltaic power plants and help promote the high-quality development of the new energy industry.
