Photovoltaic power plants are exposed to complex outdoor environments for a long time, with components blocking hot spots, loose wiring terminals generating heat, cable insulation aging, internal components of combiner boxes and inverters overheating, poor grounding and temperature rise, and other thermal hazards being highly concealed. In the initial stage, there is only a small temperature difference, which cannot be recognized by the naked eye or ordinary temperature guns in a timely manner. Long term neglect can cause component burnout, line short circuits, and in severe cases, power plant fires, resulting in huge economic losses. The traditional manual inspection and temperature measurement method has low resolution, large temperature measurement errors, and cannot visually present the temperature distribution throughout the entire area. The problems of missed detection and misjudgment occur frequently, making it difficult to meet the preventive operation and maintenance needs of large-scale power plants. Suzhou LAILX has launched the LX-F200 handheld infrared thermal imaging device, specially developed for the photovoltaic power industry. With a highly sensitive infrared detection core and intelligent temperature measurement algorithm, it accurately captures subtle temperature differences of 0.1 ℃ and presents a comprehensive temperature thermal map of the equipment. It has become an essential portable detection device for identifying thermal hazards and conducting electrical safety inspections in photovoltaic power plants. Compact, portable, precise imaging

The LX-F200 is equipped with a high-end uncooled infrared detector, which provides high-definition infrared imaging with clear layers and industry-leading temperature recognition sensitivity. It can accurately distinguish between normal working areas and abnormally high temperature points, and achieve full coverage detection for thermal faults in the entire photovoltaic field. At the component level, it quickly locates shadow occlusion and thermal spot effects caused by hidden cracks in the battery cells; Electrical equipment inspection includes various electrical hazards such as virtual connections at MC4 connectors, cable skin breakage, overheating of combiner box fuses, aging and heating of IGBT devices, and rusting and heating of distribution cabinet wiring harnesses. The device is equipped with a professional photovoltaic temperature measurement analysis mode, which supports custom environmental reference temperature, automatically shields from sunlight and environmental temperature interference, calculates real-time device temperature rise values, synchronously calculates three-phase electrical equipment phase to phase temperature differences, quantitatively evaluates the severity of faults, and provides clear and quantifiable fault judgment basis for operation and maintenance personnel, avoiding subjective judgments based on experience.

The whole machine adopts a lightweight gun style handheld ergonomic design, which is easy to work with one hand for a long time without fatigue. The body shell is made of high-strength and wear-resistant engineering plastic, with an IP65 dustproof and waterproof protection level, which is not afraid of outdoor rain, sand and dust, high and low temperature environments. The working temperature covers -10 ℃ to 55 ℃, and can be stably used in various extreme photovoltaic stations in high-altitude, coastal and desert areas. 3.5-inch high brightness touch display screen, strong outdoor visibility, clear color layering of infrared heat map, and clear distinction between hot and cold areas at a glance; The device supports automatic and manual dual-mode focusing, and the image clarity can be quickly adjusted for both long-range arrays and short-range junction boxes. Quick function buttons are set on the side of the body, eliminating the need to enter multi-level menus. One click image capture, abnormal marking, and temperature measurement point addition operations are completed, and on-site inspection operations are smooth and efficient.

The intelligent data management function is adapted to the digital operation and maintenance needs of power stations. The LX-F200 has a built-in large capacity local image library, and the infrared images captured can be easily collected and annotated with abnormal points. The library classification and filtering function can quickly retrieve all fault images, saving manual searching time. The device supports USB data export, wireless connection to mobile phones and tablets for image transmission, and is equipped with LAILX self-developed data analysis software. After importing the heatmap, it automatically generates temperature reports and fault point distribution maps. It can export inspection reports in Word and PDF formats, fully recording inspection time, station information, fault types, and temperature difference data. The operation and maintenance team establishes a standardized hidden danger ledger to achieve fault grading rectification and closed-loop management. The device supports long-term continuous inspection and is equipped with a large capacity lithium battery. It can work continuously for more than 6 hours when fully charged, meeting the needs of full area array inspection throughout the day. The backup battery can be quickly replaced without power outage or shutdown troubles.

In addition to the core application of photovoltaic power plants, LX-F200 expands to adapt to energy storage systems, high and low voltage distribution rooms, transmission lines, and industrial electrical equipment thermal detection scenarios, reducing the cost of equipment procurement for enterprises with multiple uses. Compared to imported thermal imaging equipment of the same specifications, LX-F200 relies on domestically produced core components to significantly reduce procurement and after-sales costs, while providing localized full process technical services. Equipment operation training, remote troubleshooting, and hardware maintenance response speed have been greatly improved. For large centralized photovoltaic power plants, this equipment can be paired with a tripod for precise detection and can also be mounted with drones to complete large-scale rapid cruise inspections, forming a dual layer thermal hazard investigation system of "macro aerial photography+ground handheld precision review", comprehensively eliminating blind spots in temperature measurement of the power plant.

Suzhou LAILX product engineer introduced that during the development stage of LX-F200, in-depth visits were made to hundreds of photovoltaic operation and maintenance enterprises. In response to feedback from front-line inspection personnel, pain points such as bulky equipment, inaccurate temperature measurement, and cumbersome operation were optimized and upgraded one by one, while taking into account the three core requirements of detection accuracy, portability, and intelligence. The current operation and maintenance mode of the photovoltaic industry is transitioning from post fault repair to predictive maintenance. Identifying small thermal hazards in advance can significantly reduce the cost of component replacement and line maintenance, avoid fire safety accidents, and improve the overall power generation revenue of power plants. Infrared thermal imaging detection has become a mandatory testing project for annual operation and grid connection acceptance of power plants.

The LX-F200 handheld infrared thermal imaging device, with its comprehensive advantages of precise temperature measurement, durability, and intelligent portability, connects the last mile of thermal safety detection in photovoltaic power plants. With domestically produced high-performance infrared detection equipment, it helps photovoltaic enterprises establish a normalized thermal hazard investigation mechanism, comprehensively safeguard the electrical operation safety of photovoltaic power plants, and assist new energy power plants in achieving cost reduction, efficiency improvement, safe and stable long-term operation.
