In the operation and maintenance system of photovoltaic power plants, thermal hazards such as hot spot effect, poor contact, and cable overheating are the main causes of component burnout and system failures. Real time and accurate infrared temperature detection has become a key defense line to ensure the safety of power plants. Suzhou LAILX focuses on the thermal safety needs of photovoltaic power plants and has launched the LX-F200 handheld infrared thermal imaging device. With high-resolution infrared detection, precise temperature measurement algorithms, and industrial grade portable design, it can quickly identify thermal hazards in photovoltaic modules, electrical equipment, cable joints, and other areas, providing strong technical support for safe operation and fault warning of power plants, and setting a new benchmark for photovoltaic infrared thermal imaging detection.

Photovoltaic power plants are exposed to outdoor environments for a long time and are affected by environmental factors such as light, temperature, and wind and sand. Problems such as component hot spots, poor contact of MC4 joints, overheating of combiner boxes, cable overload and overheating, and inverter failure heating occur frequently. If not detected in a timely manner, it is highly likely to cause serious accidents such as fires and component scrapping. The Suzhou LAILX LX-F200 is designed specifically for photovoltaic scenarios and is equipped with a 640 × 480 high-resolution uncooled infrared focal plane detector. The response band covers 7 μ m-14 μ m and can accurately capture temperature differences of 0.05 ℃. Whether it is local small heat spots on components, subtle heating at joints, or large-scale overheating of cables and combiner boxes, it can be clearly imaged and accurately located, achieving "early detection and early treatment" of thermal hazards. The device adopts MAGICTHERM detail enhancement technology, which can optimize the contrast of thermal images, making it easier to identify subtle temperature differences and fault areas. It is equipped with multiple imaging modes such as white hot, black hot, rainbow, and hot metal, adapting to different detection scenarios and observation habits, ensuring the intuitive presentation of fault information.

Convenient operation and powerful functions are the core advantages of LX-F200. The device adopts an ergonomic pistol grip design, with a lightweight body that can be easily operated with one hand. It is suitable for various complex detection scenarios such as roofs, mountains, and high altitudes. Operations personnel can quickly shuttle between photovoltaic arrays to achieve comprehensive inspections. Equipped with a 3.5-inch high-definition flip LCD screen, it has strong visibility under sunlight and supports real-time display of thermal images, photo storage, and video recording. Single image storage only takes 1 second, and it can continuously record full radiation thermal imaging videos, fully recording the detection process; Built in 32GB large capacity storage, capable of storing tens of thousands of hot images and video data, supporting multiple data transmission methods such as Type-C interface, WIFI, and FTP. The detection data can be quickly synchronized to computers and mobile terminals, facilitating subsequent analysis, archiving, and report generation.

LX-F200 has multiple exclusive optimization functions for the testing needs of photovoltaic power plants. The device is equipped with a built-in photovoltaic module temperature analysis algorithm, which can automatically identify the hot spot area of the module, calculate key parameters such as temperature difference and area, and intelligently determine the risk level of hot spots; Support voice and text annotation functions. Testing personnel can record 200 seconds of voice notes or input text explanations on site, accurately marking the fault location and problem description to avoid data confusion in the future. In terms of power supply, equipped with 2 3500mAh rechargeable lithium batteries, each battery can be used continuously for more than 4 hours and supports hot swapping replacement, completely solving the problem of outdoor operation endurance; The body adopts industrial grade protection design, which is waterproof, dustproof, anti drop, and resistant to high and low temperatures. It can work stably in extreme environments ranging from -20 ℃ to 50 ℃ and adapt to various harsh working conditions such as deserts, plateaus, and coastal areas.

In practical applications, the Suzhou LAILX LX-F200 handheld infrared thermal imaging device covers the entire field thermal safety detection of photovoltaic power plants. In the component inspection process, problems such as hot spots, hidden cracks, and low efficiency components can be quickly identified to locate faulty components; In electrical system testing, accurately detect hidden dangers such as poor contact, overload heating, insulation aging, etc. in combiner boxes, inverters, distribution boxes, cable joints, MC4 plugs, etc; In the acceptance and regular operation and maintenance of the power station, as an essential testing equipment, it comprehensively investigates thermal safety hazards to ensure the safety of grid connection and long-term stable operation of the power station. At present, this device has been widely used in large-scale photovoltaic power plants, operation and maintenance enterprises, and power testing institutions in China. With its precise temperature measurement, efficient and convenient characteristics, it has gained high recognition from industry customers.
