During the long-term operation of photovoltaic power plants, issues such as component hot spots, loose wiring, cable aging, abnormal combiner boxes, and inverter failures are often characterized by local heating. If these thermal hazards are not detected in a timely manner, they can lead to a significant decrease in power generation efficiency, and in severe cases, cause major safety accidents such as equipment burning and fires. Traditional point temperature detection methods have low efficiency and narrow coverage, making it difficult to achieve accurate investigation across the entire area. To solve the problem of thermal safety detection in photovoltaic power plants, LAILX in Suzhou has ingeniously created the LX-F200 handheld infrared thermal imaging device. With its core advantages of high-precision temperature measurement, high-definition thermal imaging, and convenient and efficient operation, it has become a professional tool for identifying thermal hazards and diagnosing equipment status in photovoltaic power plants, comprehensively safeguarding the safe and stable operation of power plants.

LX-F200 is a handheld infrared thermal imaging detection device customized by Lexus for the photovoltaic industry. It focuses on the precise investigation of thermal hazards in photovoltaic systems and integrates high-resolution infrared imaging, accurate temperature measurement, and intelligent analysis. It can quickly and intuitively present the surface temperature distribution of the equipment, accurately locate small hotspots, and achieve visual detection of hidden dangers such as hot spots, poor contact, overload heating, and insulation failure. The device is equipped with a high-performance infrared detector with a resolution of 640 × 480 high-definition infrared, a thermal sensitivity (NETD) below 0.05 ℃ @ 30 ℃, a temperature measurement range covering -20 ℃ to 650 ℃, supports intelligent range switching, and a temperature measurement accuracy of ± 2 ℃ or ± 2% (taking the maximum value). Even small temperature differences of 0.1 ℃ can be accurately captured, completely eliminating missed or false detections.

Compared to ordinary infrared thermal imagers, LX-F200 is deeply optimized for photovoltaic application scenarios and has multiple exclusive advantages. Firstly, there is a full screen temperature rise display and phase to phase temperature difference calculation function, which can automatically use the ambient temperature as a reference, shield environmental interference, accurately calculate the true temperature rise of the equipment and the phase to phase temperature difference of electrical equipment, making hidden danger judgment more scientific and accurate. Secondly, the device supports multiple color adjustment modes such as white hot, black hot, rainbow, and hot metal, which can be freely switched according to different detection scenarios. The thermal image details are clearer and defects are easier to identify; Level 10 image enlargement function, which can accurately enlarge the heating area and analyze the hidden danger form and location in detail.

In terms of design and operation, LX-F200 fully considers outdoor operation and maintenance needs, adopting an ergonomic pistol grip design, which can be comfortably held with one hand, flexibly operated, and not easily fatigued after long-term use; 3.5-inch high-definition LCD touch screen, supports visibility under sunlight, and still displays heat maps and data clearly under strong outdoor light. The device has a built-in large capacity storage space, supports massive heat map and video storage, and has one click photo and video recording functions. The detection data can be quickly saved, played back, and exported, making it easy to generate detection reports and archive traceability. At the same time, it supports wireless connection with mobile phones and computers to achieve real-time data transmission and remote viewing, making detection data management more efficient.

Portability and durability are prominent features of LX-F200. The whole machine is made of lightweight and high-strength engineering materials, which are sturdy, drop resistant, dustproof and waterproof, achieving IP65 protection level. It can adapt to a wide temperature range of -20 ℃ to 50 ℃ and can operate stably in various harsh outdoor environments such as deserts, mountains, beaches, roofs, etc. The device is compact in size and lightweight, equipped with a dedicated portable case for easy portability and rapid deployment. Whether it is daily inspections, troubleshooting, or regular preventive testing of power plants, it can easily handle them, greatly improving detection efficiency and coverage.

From the perspective of application scenarios, the LX-F200 handheld infrared thermal imager covers the entire field thermal safety detection of photovoltaic power plants. In the detection of photovoltaic modules, issues such as hot spots, hidden cracks, and diode failures can be quickly located to assess the health status of the modules; In electrical system testing, accurately identify potential heat hazards such as poor contact, overload, aging, etc. in combiner boxes, inverters, cables, and terminal blocks; In the acceptance stage of the power station, comprehensively inspect the quality of equipment installation and connection, and eliminate initial hidden dangers; In operation and maintenance, quickly locate the fault point, shorten maintenance time, and reduce downtime losses. At the same time, it can also be applied to thermal imaging detection and fault diagnosis in multiple fields such as photovoltaic module production, energy storage systems, and electrical equipment.

Suzhou LAILX has always been guided by industry demand, adhering to technological innovation and quality first. The LX-F200 handheld infrared thermal imaging instrument has undergone rigorous testing and verification, with stable performance and reliable quality, and has been widely recognized by industry users. The equipment is easy to operate and does not require professional training. The operation and maintenance personnel can quickly get started and carry out efficient testing, effectively reducing labor costs and improving operation and maintenance efficiency.

Safety is the lifeline of photovoltaic power plant operation, and thermal hazard investigation is a key link in safe operation and maintenance. The LAILX LX-F200 handheld infrared thermal imaging device, with its comprehensive strength of "precise temperature measurement, high-definition imaging, convenience, efficiency, and durability," has built a comprehensive thermal safety protection network for photovoltaic power plants. In the future, LAILX in Suzhou will continue to deeply cultivate photovoltaic safety testing technology, continuously optimize product performance, provide more professional and intelligent testing solutions for the photovoltaic industry, help photovoltaic power plants achieve safe, efficient, and long-life operation, and promote the high-quality development of the new energy industry.
