Photovoltaic power plants are exposed to complex outdoor environments for a long time, with hidden dangers such as component hot spots, overheating of junction boxes, virtual connections of cables, and abnormal heating of electrical connectors between combiner boxes and inverters. This type of malfunction does not show significant visual changes in the early stages and is difficult to detect with human eyes. If not dealt with in a timely manner, it will not only continue to consume power generation, but in severe cases, it may also pose a risk of fire. Traditional thermometers can only measure temperature at a single point, resulting in low inspection efficiency and inability to intuitively grasp the overall temperature distribution. Infrared thermal imaging technology, with its advantages of non-contact, large-area rapid temperature measurement and imaging, has become the core tool for inspecting photovoltaic and electrical equipment. Suzhou LAILX has launched the LX-F300 handheld infrared thermal imaging device, which is deeply optimized for photovoltaic operation and maintenance, industrial electrical testing scenarios. It combines high-sensitivity temperature measurement, rich local analysis functions, and portable operation experience, becoming a portable tool for on-site hazard investigation. Compact, portable, precise imaging

The LX-F300 is equipped with a high-performance uncooled vanadium oxide infrared focal plane detector, with a thermal sensitivity NETD of less than 0.05 ℃, which can identify very small temperature differences. The temperature difference between component cells can be clearly presented at a few tenths of a degree, without missing early weak heat spot hazards. The equipment is equipped with dual intelligent temperature measurement ranges. The conventional range of -20 ℃~120 ℃ is suitable for photovoltaic module inspection, and the high temperature range of 0 ℃~650 ℃ meets the requirements for electrical equipment fault diagnosis. The temperature measurement accuracy reaches ± 2 ℃ or ± 2%, whichever is larger, to ensure the quantification and reliability of temperature measurement data and provide objective basis for fault diagnosis. The device is equipped with MagicThermal detail enhancement imaging technology, which enhances the level of thermal image details and is paired with more than ten color palette modes. The contrast of thermal abnormal areas is distinct, and the location of heating points can be identified at a glance on site. Support the fusion of visible light and infrared images, with infrared thermal images overlaid with visible light images, making it convenient for inspection personnel to accurately locate the components and wiring terminals corresponding to faults, reducing on-site identification time.
As a handheld device designed for frontline sites, the LX-F300 fully optimizes the human-machine operation experience. The body is comfortable to hold, lightweight, and not easily fatigued during long-term outdoor inspections. 5-inch explosion-proof touch screen, clear image under strong light, supports touch operation, customizable programmable shortcut keys, one click access to commonly used temperature measurement functions, improving inspection speed. The instrument has a complete set of professional analysis functions built-in, which can complete diagnosis on site without returning to the computer. It supports temperature measurement at the center point and the highest and lowest average temperature measurement in the area. It has full screen temperature rise display and automatic calculation of phase to phase temperature difference function, which can shield environmental temperature interference and directly output device temperature rise data. Support isotherm setting, highlight areas exceeding the set temperature, and quickly screen abnormal components in a large batch of photovoltaic arrays. The device supports full radiation thermal imaging video recording, which fully records the dynamic changes in temperature. The images and videos are embedded with all the original temperature data, which can be reanalyzed and replayed in computer software for easy fault tracing and archiving.

In terms of data management and transmission, the LX-F300 supports local storage on SD cards, automatic naming of images through scanning, on-site scanning of component barcodes, automatic binding of component numbers to thermal imaging images, and the ability to quickly mark abnormal images with a bookmark feature, making later retrieval and archiving very convenient. The device has multiple transmission methods such as WiFi FTP, Type-C, HDMI, etc. The thermal imaging files can be quickly transferred to a computer or terminal, and are equipped with PC analysis software to batch process images and output inspection reports. In addition to detecting thermal spots on photovoltaic modules, junction boxes, combiner boxes, and inverters, the LX-F300 is also suitable for temperature inspection of high and low voltage electrical cabinets, cable lines, energy storage equipment, HVAC equipment, and industrial equipment. It has multiple uses and improves equipment utilization.

Nowadays, the operation and maintenance of photovoltaic power plants are developing towards scale and intelligence, and pre inspection of safety hazards is of paramount importance in the operation and maintenance work. The LX-F300 handheld infrared thermal imaging device condenses professional industrial thermal imaging capabilities into a handheld portable device, intercepting early heat hazards in the bud stage, reducing safety accidents, and minimizing power generation losses. Suzhou LAILX is based on the new energy testing industry, fully understanding the real pain points of frontline operation and maintenance engineers. The equipment balances performance, reliability, and usability, and is suitable for many users such as operation and maintenance enterprises, EPC engineering, third-party testing institutions, and power units. It provides reliable domestic equipment for safety inspections in the photovoltaic and industrial fields, helping the industry operate safely and efficiently.
