Photovoltaic power plants are exposed to outdoor environments all year round, and faults such as component hot spots, loose connection terminals, cable aging and damage, and abnormal temperature rise of combiner boxes and inverter equipment are very common. These hidden dangers will only manifest as local small temperature rises in the early stage, which cannot be recognized by the naked eye. If not promptly investigated and dealt with, it can cause a continuous decrease in power generation, and in severe cases, lead to component burning and electrical fire accidents, causing property losses to the power plant. Traditional manual inspection relies on visual observation and contact temperature measurement methods, which result in low work efficiency and easy omission of subtle temperature rise hazards. Infrared thermal imaging non-contact temperature measurement technology has become the mainstream method for equipment hazard investigation in the new energy industry. Suzhou Laikesi LAILX combines the actual working conditions of photovoltaic operation and maintenance, industrial electrical inspection, and launches the LX-F300 handheld infrared thermal imaging instrument, which combines the advantages of high-precision temperature measurement, high-definition thermal imaging, durability, portability and ease of use. It is not only suitable for the full chain thermal hazard investigation of photovoltaic power plants, but also meets the detection needs of various scenarios such as industrial electrical and equipment maintenance. Compact, portable, precise imaging

The LX-F300 handheld infrared thermal imaging device is equipped with a high-performance uncooled infrared focal plane detector, which has excellent thermal sensitivity and can capture extremely small temperature differences. It can transform the temperature distribution that cannot be seen by the human eye into an intuitive thermal imaging image and quickly locate the local hotspots of the device. The device is equipped with a dual range intelligent switching mode, suitable for temperature measurement of photovoltaic modules and ordinary electrical equipment from -20 ℃ to 120 ℃. The large range from 0 ℃ to 650 ℃ can cope with high-temperature electrical faults and industrial equipment detection. The temperature measurement accuracy meets industrial detection standards, and whether it is small hot spots on photovoltaic cells or abnormal overheating of distribution cabinet wiring, it can be accurately identified and located. The instrument adopts visible light and infrared dual light fusion technology, and the thermal imaging image is overlaid with the visible light real scene image. On site personnel can quickly locate the specific location of the heating without confusion in identifying the fault point, greatly improving the efficiency of on-site investigation.

The whole machine is built according to industrial outdoor use standards, with a handheld ergonomic design that is easy to hold and inspect for a long time without fatigue. The body is anti fall and dustproof, suitable for harsh environments such as wind, sand, and large temperature differences in outdoor power stations. The high-resolution display screen is clear and visible in strong outdoor light environments. The quick key layout on the body is reasonable, and there is no need for complex menu jumps. Temperature measurement point settings, isotherm threshold settings, image shooting, and thermal imaging video recording can be completed on site. The device supports multi-point temperature measurement, which can simultaneously view the highest temperature, lowest temperature, and center point temperature. It also supports line temperature measurement function, allowing for intuitive viewing of temperature gradient changes along a line. The device can also customize temperature alarm thresholds. Once an area exceeds the set temperature appears on the screen, the instrument will immediately alert the staff to avoid missing key hazards.

Capture and store full radiation heat maps, and subsequently adjust temperature measurement parameters in computer software to conduct in-depth data analysis. The images support adding text and voice notes, and the fault location and equipment number can be directly recorded on site, making it convenient to organize the operation and maintenance ledger in the later stage without the need for repeated recording of information.
In the operation and maintenance scenario of photovoltaic power plants, the LX-F300 can complete thermal spot inspection of photovoltaic modules, quickly identifying components that are obstructed or have damaged solar cells causing thermal spot effects; Conduct infrared temperature measurement on the junction terminals, fuses, inverter power devices, distribution cabinets, and cable joints of the combiner box to identify electrical hazards such as virtual connections, overload aging, etc. In addition to the new energy industry, this instrument is also widely used in industrial scenarios such as power inspection, mechanical equipment fault diagnosis, HVAC testing, etc. Compared to similar products abroad, the LX-F300 is optimized based on the usage habits of frontline engineers in China. Its operation logic is simple and easy to understand, without complex redundant settings. Ordinary operation and maintenance personnel can proficiently get started after a short training. At the same time, it has obvious advantages in price, parts supply, and after-sales maintenance cycle. At present, with the continuous expansion of the photovoltaic stock market and the increasing pressure on safety operation and maintenance, infrared thermal imaging inspection has become a necessity for operation and maintenance from an optional tool. The LAILX LX-F300 handheld infrared thermal imaging instrument, with its precise temperature measurement, sturdy portability, and comprehensive functions, helps operation and maintenance personnel detect various potential heating risks in advance, eliminate faults in the bud stage, safeguard power plant equipment and personal safety, and assist the upgrading of operation and maintenance work in the new energy industry towards intelligent and predictive operation and maintenance.
