In the operation and maintenance system of photovoltaic power plants, infrared thermal imaging detection is the core means of quickly locating obvious faults such as hot spots, joint overheating, cable aging, and diode failure. It is crucial for preventing power plant fires, reducing equipment losses, and ensuring stable power generation. With the development of photovoltaic power plants towards high power, high density, and scale, traditional infrared detection equipment has problems such as low resolution, inaccurate temperature measurement, complex operation, and poor portability, which cannot meet the requirements of efficient and accurate on-site detection. Suzhou LAILX has been deeply involved in the field of photovoltaic detection for many years, and has innovatively launched the LX-F200 handheld infrared thermal imaging instrument. With high-resolution infrared detection, precise temperature measurement, intelligent analysis, and super portable characteristics, it has become an ideal choice for thermal imaging detection of photovoltaic power plants. High sensitivity and clear imaging

Photovoltaic power plants are exposed to complex outdoor environments for a long time, which are eroded by factors such as sun exposure, rain, wind and sand, and humidity. Thermal hazards such as component hot spots, loose wiring terminals, cable aging, inverter failures, and abnormal combiner boxes occur frequently. These hidden dangers often manifest in the form of localized heating in the early stages. If not detected and dealt with 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 fires and equipment burns. Traditional temperature measuring devices such as temperature guns and infrared thermometers can only measure temperature at a single point and cannot visually present the overall temperature distribution of the equipment, making it difficult to locate hidden thermal hazards; However, traditional thermal imaging devices have large volume, heavy weight, complex operation, poor outdoor portability, low resolution, insufficient temperature measurement accuracy, and cannot accurately capture subtle temperature differences, making it difficult to meet the refined operation and maintenance needs of photovoltaic power plants. The LAILX LX-F200 handheld infrared thermal imaging device has emerged, accurately solving industry pain points and providing hardcore support for thermal safety inspections of photovoltaic power plants.

High sensitivity infrared detection and high-definition imaging accurately capture fine and micro thermal anomalies. The LX-F200 is equipped with an imported high-sensitivity uncooled infrared focal plane detector, with a response band covering the long wave infrared range of 7 μ m-14 μ m. It has a high-definition infrared resolution of 640 × 480, a thermal sensitivity of<0.05 ℃ @ 30 ℃, and can accurately distinguish subtle temperature differences of 0.05 ℃, effectively avoiding interference from environmental dust, water vapor, and smoke, and stably capturing target infrared radiation signals in complex and harsh environments. The temperature measurement range of the equipment covers -25 ℃ to 560 ℃, which can meet the temperature measurement needs of photovoltaic modules, junction boxes, combiner boxes, inverters, cable lines and other equipment. It clearly presents the surface temperature distribution of the equipment, accurately locates hidden dangers such as hot spots, overheated joints, and aging cables, and the imaging image has clear colors and details. Even small hot spots on the edges of photovoltaic modules can be clearly identified.

Accurate temperature measurement and intelligent analysis enhance the efficiency of fault diagnosis. LX-F200 has intelligent functions such as multi-point temperature measurement, temperature difference analysis, high temperature alarm, isotherm annotation, etc. It can display the temperature of the temperature measurement point, the highest temperature, the lowest temperature, and the average temperature in real time, automatically mark the high temperature area, and trigger the sound and light alarm when the temperature exceeds the set threshold, reminding the operation and maintenance personnel to handle it in a timely manner. The device is equipped with a photovoltaic specific temperature measurement algorithm, optimized for detecting thermal spots on photovoltaic modules. It can automatically distinguish between normal temperature differences and faulty thermal anomalies, reducing misjudgments; Support the fusion and comparison of thermal images and visible light images, intuitively locate the specific location of thermal hazards on the equipment, and facilitate quick troubleshooting by operation and maintenance personnel. At the same time, the device can store tens of thousands of thermal image data, support one click export and Bluetooth transmission, and is equipped with computer analysis software for data playback, comparative analysis, and report generation, providing data support for fault tracing and operation and maintenance decision-making.

Lightweight, portable, and user-friendly design, suitable for long-term outdoor work. The LX-F200 adopts an ergonomic lightweight design, with a total weight of only 0.9kg. It can be easily held and operated with one hand, making it less prone to fatigue during long-term outdoor inspections; The body is compact and can be carried in a portable bag, suitable for various photovoltaic power plant sites such as mountains, rooftops, and water surfaces, solving the problem of poor portability of traditional equipment. The device is equipped with a 3.5-inch high-definition touch screen display, which provides clear visual effects under strong light. The operation interface is simple and intuitive, supporting dual operation of touch and buttons. It can also be easily operated with gloves; Built in large capacity lithium battery with a battery life of up to 12 hours, meeting all day outdoor testing needs, supporting fast charging, and can be used for 4 hours after 1 hour of charging. At the same time, the equipment casing adopts anti slip, anti drop, and waterproof design, with a protection level of IP54, suitable for harsh outdoor environments, anti drop, dustproof, and waterproof, improving the durability and service life of the equipment.

Multi scenario adaptation and wide application, empowering photovoltaic full scenario safe operation and maintenance. LX-F200 is designed specifically for photovoltaic power stations and is widely used in scenarios such as hot spot detection of photovoltaic modules, overheating inspection of wiring terminals, fault diagnosis of combiner boxes and inverters, aging detection of cable lines, and positioning of poor grounding and heating. It can also be extended to fields such as power inspection, industrial equipment temperature measurement, and building energy conservation testing. In the daily operation and maintenance of photovoltaic power plants, operation and maintenance personnel can quickly scan the component array with handheld devices to detect thermal spot hazards in real time; Regularly conduct temperature measurement and testing on electrical equipment such as combiner boxes and inverters to provide early warning of overheating faults; Inspect cable joints, junction boxes, and other heat prone areas to prevent safety accidents from occurring. At present, the device has been put into use in many photovoltaic power plants and power operation and maintenance enterprises in China. With accurate detection performance and convenient operation experience, it has become a "safety sentinel" for photovoltaic operation and maintenance personnel.

Suzhou LAILX has always focused on the field of photovoltaic safety testing, driven by technological innovation and guided by user needs. The launch of LX-F200 handheld infrared thermal imaging instrument further improves the company's photovoltaic testing product matrix. In the future, LAILX will continue to deepen its research and development of infrared thermal imaging technology, continuously optimize product performance, enhance equipment intelligence level, and provide professional technical training and after-sales service to help photovoltaic power plants achieve safe, efficient, and stable operation, and safeguard the high-quality development of the photovoltaic industry.
