Photovoltaic power plants operate outdoors for a long time and are susceptible to corrosion from ultraviolet rays, rainwater, dust, and temperature differences. They are prone to component hot spots, loose MC4 connectors, overheating of combiner box cables, aging of inverter components, poor grounding contact, and other heating faults. If small thermal hazards are not promptly investigated, they can gradually expand, causing component burnout, line short circuits, and even power plant fires, resulting in huge economic losses. Infrared thermal imaging detection, with its advantages of non-contact, long-distance, and visual temperature measurement, has become the core means of preventive operation and maintenance of photovoltaics. However, traditional handheld thermal imagers have shortcomings such as low resolution, insufficient temperature sensitivity, blurry outdoor strong light imaging, and poor portability and comfort, making it difficult to meet the needs of precision inspection of photovoltaics. Suzhou Laikesi LAILX focuses on photovoltaic thermal safety detection scenarios and has developed and launched the LX-F200 handheld infrared thermal imaging device. With high-definition infrared detection, ultra-high temperature sensitivity, photovoltaic special optimization, and industrial grade durable design, it achieves rapid and accurate identification of thermal hazards throughout the power plant. Compact, portable, precise imaging

The LX-F200 is equipped with a 640 × 480 high-resolution uncooled infrared focal plane detector, with a response band covering the 7-14 μ m photovoltaic specific spectral range. It is equipped with a built-in solar reflection filter, which effectively filters outdoor strong light infrared interference. During daytime inspection, the imaging is free of reflection and distortion, and the fine temperature distribution of the components is clearly presented. The thermal sensitivity of the equipment is as low as 35mK, which can accurately capture small temperature differences of 0.035 ℃. It can identify early weak heat spots and joint micro heating hazards that cannot be detected by conventional thermal imagers, and avoid major safety accidents from the source; The temperature measurement range supports dual range intelligent switching, and is suitable for daily inspection of photovoltaic modules and wiring terminals from -20 ℃ to 120 ℃. The temperature range of 0 ℃ to 650 ℃ meets the high temperature fault detection of inverters, box transformers, and high-voltage cables. The temperature measurement accuracy can reach ± 2 ℃ or ± 2% reading, and the temperature measurement data has metrological traceability. The detection results can be used as an effective basis for power plant safety assessment.

The whole machine adopts an ergonomic single handed grip design, with a lightweight body treatment. Long term inspection with one hand grip is not easy to fatigue. The anti slip rubber shell is matched with an anti drop buffer structure, which is not easily damaged by outdoor bumps and falls; 3.5-inch high-definition touch display screen, high visibility under strong light, can clearly view thermal imaging images without shading, supports multi-point temperature measurement, isotherm labeling, temperature difference comparison function, and can quickly determine the severity of faults on site. The device is equipped with a large capacity rechargeable lithium battery, which can work continuously for 6 hours on a single full charge. Equipped with a fast charging interface, the operation and maintenance team can conduct full day inspections without the need for power outages; Support local storage of tens of thousands of thermal imaging images, with automatic recording of shooting temperature, GPS location, and device number. Equipped with wireless transmission function, real-time synchronization of thermal images to mobile APP, on-site annotation of fault information, and one click generation of temperature measurement inspection report.

The LX-F200 has a dedicated optimization function for the photovoltaic industry, which greatly improves operation and maintenance efficiency. It is equipped with an intelligent analysis algorithm for photovoltaic thermal spots, which automatically identifies local high-temperature areas of components, distinguishes between normal temperature rise and dangerous thermal spots, automatically marks the coordinates, maximum temperature, and temperature difference values of thermal spots, and reduces manual interpretation errors; Support scanning and binding component barcodes, automatically associating each thermal imaging image with the corresponding array and component number. No manual information entry is required for later operation and maintenance ledger organization, doubling the efficiency of large-scale power plant inspection and archiving. In addition to photovoltaic module testing, the equipment can also cover temperature measurement of all electrical equipment such as combiner boxes, distribution cabinets, inverters, box type transformers, cable trays, and grounding metal parts. One set of equipment meets all infrared inspection needs of the power station and reduces the procurement cost of multiple equipment for operation and maintenance enterprises.

The equipment protection level reaches IP67, which is dust-proof and waterproof, and can resist rainstorm and sand invasion. The operating temperature range covers -40 ℃ to 60 ℃. Extreme photovoltaic projects such as northwest desert, southern coastal high humidity and plateau low temperature can operate stably; The lens is equipped with a replaceable protective cover to prevent outdoor sand and gravel from scratching the infrared lens and extend the service life of the equipment. LAILX provides a complete set of metrological calibration services for LX-F200, and can issue a formal infrared temperature measurement calibration certificate every year, which meets the safety testing requirements of the power and photovoltaic industries. The equipment is equipped with professional PC analysis software, supporting batch processing of thermal imaging images, export of temperature curves, and analysis of annual hidden danger trends, providing complete data support for long-term safe operation and maintenance of power plants.

Under the industry trend of promoting standardized safety operation and maintenance of photovoltaic power plants, thermal imaging preventive inspection has become an essential process for power plant operation and maintenance. The LX-F200 handheld infrared thermal imaging device, with its advantages of high-definition imaging, ultra-high sensitivity, photovoltaic special optimization, portability and durability, solves the pain points of traditional temperature measurement equipment missed detection, cumbersome operation, and poor outdoor adaptability. It is widely used in centralized photovoltaic, household distributed, industrial and commercial rooftop photovoltaic, wind power supporting stations, power distribution facility inspection and other scenarios. Suzhou LAILX always adheres to the localization innovation of photovoltaic detection equipment, continuously iterates the infrared thermal imaging series products, safeguards the thermal safety of photovoltaic power plants nationwide with accurate and reliable temperature measurement equipment, and helps the new energy industry build a complete and pre installed safety operation and maintenance system.
