In fields such as photovoltaic power plants, power systems, and industrial equipment, abnormal temperature is an important warning signal for equipment failure and performance degradation. The problems of hot spots on photovoltaic modules, overheating of inverters, poor line contact, and overload of electrical equipment are all intuitively reflected through temperature changes. Traditional contact temperature measurement methods are inefficient, have a small range, and pose safety hazards, making it difficult to meet the needs of large-scale and rapid detection. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) focuses on the pain points of temperature measurement in the industry and has launched the LX-F200 handheld infrared thermal imaging device. With the core advantages of high-definition infrared imaging, precise temperature measurement, and convenient operation, it achieves non-contact rapid temperature detection and thermal hazard location, providing efficient solutions for photovoltaic power plant operation and maintenance, power equipment maintenance, and industrial fault diagnosis.

LX-F200 is a professional handheld infrared thermal imaging device specially designed by LAILX for hot spot detection in photovoltaic power plants and troubleshooting of power systems. Its core performance is benchmarked against industrial standards. The device is equipped with a high-sensitivity infrared detector with 384 × 288 high-definition infrared resolution, paired with an 8-14 μ m infrared spectral band, which can accurately capture small temperature differences on the surface of objects. The temperature measurement range covers -20 ℃~650 ℃, supports intelligent multi range switching, and the temperature measurement accuracy is as high as ± 2 ℃ or ± 2% (whichever is larger). Whether it is fine thermal spots on photovoltaic modules or high-temperature fault points on electrical equipment, it can be imaged clearly and accurately measured. It adopts advanced infrared imaging algorithms, with automatic gain and white balance functions, and is equipped with a 5-megapixel visible light camera. It supports four image modes: thermal imaging, visible light, fusion, and picture in picture. It can intuitively compare the location of thermal defects with the actual scene, making it easy to quickly locate the fault point.

For the detection scenario of photovoltaic power plants, LX-F200 has multiple exclusive optimization functions. The device supports full screen temperature rise display function, which can set the ambient temperature as the benchmark, automatically shield environmental temperature interference, accurately calculate the actual temperature rise values of components and devices, and effectively eliminate the influence of outdoor lighting and ambient temperature on the detection results. At the same time, it has the function of calculating phase to phase temperature difference, which can automatically analyze the temperature difference data between electrical equipment phases and at both ends of the line, providing scientific basis for equipment fault diagnosis. For the detection of hot spots on photovoltaic modules, the equipment supports automatic tracking of high and low temperatures, temperature measurement at the center point, and temperature analysis in the 5:05 area. It can quickly lock the location of module hot spots and areas with abnormal temperatures. At the same time, it is equipped with a two-level laser pointer to accurately mark abnormal points, making it easy for operation and maintenance personnel to review and repair on site. In addition, the device supports 7 color palette switches (iron red, rainbow, white hot, black hot, etc.), which can select the optimal display mode according to different detection scenarios and object characteristics to improve defect recognition clarity.

Convenience and practicality are the core design highlights of LX-F200. The whole machine adopts an ergonomic pistol grip design, with a lightweight and portable body that can be easily operated with one hand. It is equipped with a 3.5-inch high-definition LCD landscape screen, with clear images, wide viewing angles, and good visibility under strong light. The layout of the operation buttons is reasonable, the functional zoning is clear, and it supports one click photography, video recording, and data storage. It has a built-in large storage space, supports SD card hot plugging, and can expand up to 2TB to meet the needs of massive data storage. The device is designed with a detachable rechargeable lithium battery, which has strong endurance and supports independent charging of the battery. There is no need to worry about power outages during outdoor testing. At the same time, it has an IP54 protection level, resistant to falls, dust, and water, and can adapt to outdoor working environments ranging from -20 ℃ to 50 ℃. It can operate stably in complex working conditions such as sandstorms, rain, snow, and high temperatures, and is sturdy and durable.

The intelligent and digital functions enable the LX-F200 to break through the limitations of traditional thermal imaging instruments and upgrade to a predictive maintenance (PdM) data terminal. The device supports WIFI wireless transmission function, which can connect mobile APP and professional analysis software on PC to achieve real-time transmission, remote viewing, data sharing, report generation and other functions of thermal images. Testing personnel can synchronously transmit thermal imaging data to the backend on site, and backend technicians can analyze faults in real time and guide on-site maintenance, greatly improving the efficiency of testing and maintenance collaboration. The device has a collection and annotation function, which can quickly mark abnormal thermal images and support quick filtering and searching in the library, making it easy to organize and trace data in the later stage. Simultaneously supporting isothermal analysis, temperature trend analysis, data export (Excel, PDF format) and other functions, providing complete data support for equipment status assessment, fault prediction, and operation and maintenance report generation.

From the perspective of application scenarios, the LX-F200 handheld infrared thermal imager has a wide range of applications. In the field of photovoltaics, it can quickly detect issues such as component hot spots, junction box overheating, inverter faults, and abnormal combiner box circuits, ensuring the power generation efficiency and operational safety of the power station; In the field of electricity, it can be used for troubleshooting overheating faults in equipment such as transformers, switchgear, cables, motors, etc., to prevent safety accidents such as short circuits and fires; In the industrial field, it can be applied to equipment temperature monitoring, production process monitoring, and other industries such as metallurgy, chemical engineering, and machinery to achieve predictive maintenance and reduce unplanned downtime. With the advantages of being versatile, precise and efficient, LX-F200 has become an essential tool for photovoltaic power station operation and maintenance teams, power maintenance departments, and industrial enterprise equipment management.
