Photovoltaic power plants are exposed to complex outdoor environments for a long time, with thermal hazards such as component hot spots, loose wiring terminals, cable aging, inverter failures, and abnormal combiner boxes, which are the main causes of safety accidents such as component burnout, system short circuits, and fires. At the same time, they directly lead to a decrease in power generation efficiency and loss of revenue. Traditional temperature measurement methods such as temperature guns and contact thermometers have problems such as low detection efficiency, limited coverage, inability to visually present thermal distribution, and difficulty in detecting early hidden dangers, which cannot meet the comprehensive, rapid, and accurate thermal hazard investigation needs of photovoltaic power plants. Suzhou LAILX focuses on the pain points of thermal safety operation and maintenance in photovoltaic power plants, and has launched the LX-F200 handheld infrared thermal imaging device. With the core advantages of high sensitivity detection, high-definition imaging, precise temperature measurement, and portable intelligence, it provides efficient solutions for identifying thermal hazards in photovoltaic power plants and strengthens the defense line for safe operation of power plants.

Infrared thermal imaging technology converts invisible infrared energy into visible thermal images by detecting the infrared radiation emitted by objects, visually presenting the temperature distribution on the surface of objects. It has advantages such as long-distance, non-contact, full coverage, fast imaging, and precise temperature measurement. It is the core technical means for identifying thermal hazards, detecting electrical equipment, and diagnosing equipment faults in photovoltaic power plants. LAILX has been deeply involved in the field of photovoltaic testing for many years, providing precise insights into the thermal safety and operation needs of photovoltaic power stations. Combined with the accumulation of industrial infrared imaging technology, we have independently developed the LX-F200 handheld infrared thermal imaging instrument, which is specially designed for photovoltaic scenarios, taking into account professional performance and portable operation, and is suitable for the full scene thermal testing needs of photovoltaic power station components, electrical equipment, cables, etc.

The LX-F200 handheld infrared thermal imaging device is equipped with high-end core detection components, creating a foundation for precise temperature measurement and high-definition imaging. The equipment adopts imported high-sensitivity uncooled infrared focal plane detectors, with a response band covering the long wave infrared range of 7 μ m to 14 μ m. It has strong penetration and anti-interference ability, which can effectively avoid environmental dust, water vapor, and smoke interference, and stably capture target infrared radiation signals in complex and harsh environments. The thermal sensitivity of the detector is less than 0.05 ℃ @ 30 ℃, and it can distinguish subtle temperature differences of 0.05 ℃, accurately capturing early small thermal hazards and avoiding safety accidents caused by the expansion of hazards. The device has high imaging resolution, clear and delicate images, distinct color layers, and can clearly present details such as component hot spots, cable joint overheating, and local abnormal heating of the equipment, making it easy for operation and maintenance personnel to accurately locate the fault location.

In terms of temperature measurement performance and functional design, LX-F200 is fully adapted to the detection needs of photovoltaic power plants, with comprehensive and practical functions. The temperature measurement range of the equipment covers -20 ℃ to 550 ℃, which can meet the temperature measurement needs of various devices such as photovoltaic modules, inverters, combiner boxes, cables, junction boxes, etc; The temperature measurement accuracy is as high as ± 2 ℃ or ± 2% reading, accurate and reliable, providing accurate data support for fault diagnosis. The device supports full screen emissivity correction, multi-point temperature measurement, temperature difference analysis, temperature alarm and other functions, which can quickly locate high-temperature areas, set temperature thresholds, automatically alarm for overheating, and improve the efficiency of hidden danger investigation. At the same time, the device is equipped with a high brightness IPS touch screen, which is visible under sunlight. The operation interface is simple and intuitive, supporting real-time image display, enlargement, freezing, and saving, making it easy to quickly view and analyze on site.

Portable and durable design is the core advantage of LX-F200 in adapting to photovoltaic field operations. The whole machine adopts a lightweight ergonomic design, which is lightweight, comfortable to hold, easy to operate with one hand, and less prone to fatigue during long-term operation; The body is made of high-strength engineering materials, with dust-proof, waterproof, and anti drop performance. The protection level meets the standard and can adapt to harsh outdoor environments such as high temperature, low temperature, humidity, and sand and dust, meeting the needs of long-term field inspections. The equipment is equipped with rechargeable lithium batteries that support on-site replacement and have a long battery life, meeting the needs of all day inspection operations; Supports SD card storage, capable of storing a large amount of thermal images and temperature measurement data, with a USB interface for easy data export, archiving, and analysis, providing data support for fault tracing and operation report generation.

The LX-F200 handheld infrared thermal imaging device has a wide range of application scenarios and significant value in the operation and maintenance of photovoltaic power plants. In the detection of photovoltaic modules, the entire module array can be quickly scanned to accurately detect issues such as hot spots, hidden cracks, virtual soldering, and aging of battery cells, avoiding the long-term existence of hot spots that can cause module burnout and power attenuation; In electrical equipment testing, temperature measurement can be carried out on inverters, combiner boxes, distribution cabinets, wiring terminals, etc. to identify potential overheating hazards caused by poor contact, overload, component aging, etc., and prevent short circuits and fire accidents; In online cable inspection, it can quickly detect local overheating caused by aging, damage to the insulation layer, and loose joints of the cable, avoiding the risk of leakage and short circuit; In the daily inspection of power stations, the efficient imaging detection mode significantly shortens the inspection time, reduces operation and maintenance costs, and enhances the intelligence level of power station operation and maintenance.

In addition to the photovoltaic field, LX-F200 can also be widely used in multiple fields such as power inspection, industrial equipment testing, building HVAC testing, fire hazard investigation, scientific research experiments, etc. It is versatile and cost-effective.
