The DC system, components, combiner boxes, inverters, and cable joints of photovoltaic power plants are exposed to high temperatures, humidity, and sandstorms outdoors for a long time. Thermal faults such as oxidation and looseness of wiring terminals, hidden cracks and hot spots in components, diode failure, cable insulation aging, and overheating of inverter power modules are highly concealed and cannot be identified by routine visual inspections. If left unchecked for a long time, it can cause significant losses such as component burnout, cable fires, and equipment shutdown. Traditional large-scale infrared thermal imaging equipment is bulky, and handheld models have problems such as insufficient temperature measurement accuracy, blurry images, unclear outdoor strong light, short battery life, and lack of photovoltaic specific analysis functions. The efficiency of large-scale inspections by operation and maintenance personnel is low, making it difficult to achieve a comprehensive investigation of thermal hazards without blind spots throughout the entire station. Based on the real needs of photovoltaic operation and maintenance, Suzhou Laikesi LAILX has launched the LX-F100 handheld infrared thermal imaging device, which provides a lightweight and efficient solution for photovoltaic field thermal fault diagnosis with a portable body, high-precision temperature measurement, and photovoltaic exclusive intelligent analysis function, revolutionizing the infrared inspection operation mode of power plants. Compact, portable, precise imaging

The LX-F100 features a palm to hand integrated handheld design, with a compact and lightweight body that can be held with one hand without heavy pressure. Equipped with an anti slip rubber grip, it is not easy to fatigue during long-term outdoor inspections and can be carried to narrow inspection points such as roofs, bracket gaps, cable trenches, etc. without the need to transport large equipment. The core is equipped with a high-resolution infrared detector, paired with a high-definition visible light dual light fusion lens. The infrared image is synchronously overlaid with the real scene image, accurately locating the heating point. The screen automatically brightens up in outdoor strong light environments, and is not afraid of direct sunlight at noon. The imaging details are clear and distinguishable, and there are no missing small heating nodes. The temperature measurement performance meets industrial standards, covering a temperature range of -20 ° C to 300 ° C. The sensitivity of temperature difference recognition is extremely high, and a small temperature difference of 0.05 ° C can be captured, accurately distinguishing between normal and abnormal overheating. It accurately measures various faults such as thermal spots on photovoltaic modules, virtual connection heating of wiring terminals, diode loss in combiner boxes, IGBT overheating in inverters, and insulation damage heating in cables. It synchronously displays real-time temperature, highest temperature, lowest temperature, and temperature difference values, and the data is intuitive and readable.

The device is equipped with an exclusive intelligent analysis algorithm for the photovoltaic industry, with four preset detection modes for photovoltaic modules, combiner boxes, inverters, and cables upon startup, allowing for one click switching without the need for manual parameter tuning. When an abnormally high temperature area is detected, the instrument will automatically sound and light an alarm, mark the outline of the high temperature area, automatically calculate the temperature difference, quickly determine the risk level of the fault, distinguish between minor losses and high-risk fire hazards, and allow operation and maintenance personnel to prioritize high-risk points, optimize the sequence of inspection operations, and greatly improve the efficiency of fault disposal. Support custom temperature measurement threshold, set warning temperature according to different rated operating conditions of devices, and adapt to the detection needs of photovoltaic systems with different voltage levels. The body is equipped with a large-sized touch color screen, with simple and intuitive operation logic. Operations personnel do not need professional thermal imaging knowledge, and can independently complete site inspections with simple teaching.

Outdoor durability and endurance fully adapt to photovoltaic field operations. The whole machine has IP65 dust and waterproof protection, anti drop body design, and can work stably in unexpected drops, rainwater spraying, and sandstorm environments. It is suitable for various complex power plant environments such as northwest deserts, southern rainy coastal areas, and mountainous dusty areas. Equipped with a large capacity rechargeable lithium battery, the continuous infrared shooting time can reach 8 hours, meeting the requirements of uninterrupted inspection throughout the day; Supports fast charging function, paired with a portable charging case, ensuring no power outage during outdoor inspections. The body is equipped with a local storage module, which can store tens of thousands of infrared thermal images. Each image is automatically labeled with shooting time, temperature data, and device location. It supports Bluetooth and USB export of images to computers and mobile phones, and is matched with LAILX dedicated operation and maintenance software. It automatically generates infrared inspection reports, summarizes the heating fault locations and temperature data of the entire station, and forms a complete operation and maintenance file, which facilitates annual comparison, fault tracing, and power station safety audit.

In addition to the operation and maintenance of photovoltaic power stations, LX-F100 is also suitable for temperature measurement scenarios in multiple fields such as new energy distribution rooms, energy storage cabinets, industrial electrical circuits, and building insulation testing, reducing the cost of equipment procurement for enterprises with multiple uses. At present, the instrument has been widely deployed in photovoltaic operation and maintenance companies, power maintenance units, and third-party safety testing institutions in various provinces and cities across the country. Frontline operation and maintenance personnel have generally reported that the handheld body greatly improves inspection mobility, dual light fusion imaging avoids point misjudgment, and intelligent warning function greatly shortens fault investigation time, effectively reducing fire safety hazards in photovoltaic power plants. The market leader of LAILX in Suzhou stated that LX-F100 is a core product developed by the brand for lightweight on-site inspections, focusing on the needs of frontline operation and maintenance personnel to reduce workload and increase efficiency, balancing the three core indicators of portability, accuracy, and durability. In the future, the brand will continue to iterate thermal imaging algorithms, add quantitative calculation functions for thermal spot loss, and connect thermal imaging data with power plant operation and maintenance management systems. With intelligent handheld detection devices, it will assist in the safe and lean operation and maintenance of photovoltaic power plants, and safeguard the safe and stable development of the new energy industry.
