Photovoltaic power plants are exposed to outdoor environments for a long time, posing major risks to the safe operation of the power plant, such as component heat spots, loose wiring terminals, aging cables, and overheating of combiner box components. Traditional contact temperature measurement tools can only collect temperature at a single point, and the inspection of the entire photovoltaic array requires a lot of time. The efficiency of large-scale investigation is low, and small heating points are easily missed. Infrared thermal imaging technology relies on non-contact global temperature measurement, and can obtain the temperature distribution of the entire area in one scan, becoming an important tool for hidden danger investigation in the fields of new energy and power industry. Suzhou Laikesi LAILX combines the actual working conditions of photovoltaic operation and maintenance sites to create the LX-F300 handheld infrared thermal imaging device, which combines high-definition infrared imaging, high-precision temperature measurement, and one handed portable operation. It provides professional detection equipment for the safety inspection of photovoltaic power plants and electrical equipment, helping operation and maintenance personnel to capture various heating anomalies in advance, avoid equipment burning and fire accidents, and safeguard the safety of power plant assets and power generation income. High sensitivity and clear imaging

The LX-F300 handheld infrared thermal imaging device is equipped with a high specification non cooled vanadium oxide infrared detector, which has high infrared resolution and excellent thermal sensitivity. It can capture very weak temperature differences and identify early minor thermal spots in components, so as not to be discovered only after the fault is severe. Temperature measurement covers a wide range from 20 ℃ to 650 ℃, with an emissivity adjustable from 0.01 to 1.00. It is suitable for measuring objects made of various materials such as glass, metal, and plastic, ensuring accurate and reliable temperature measurement data from different devices. The device supports manual focusing, with a minimum focusing distance of 0.1 meters. Whether scanning the entire photovoltaic array from a distance or observing small parts of wiring terminals and components up close, it can output clear thermal imaging images. Combined with digital zoom function, it further magnifies and observes local details. The body adopts a handheld gun style ergonomic design, which is lightweight and not easy to fatigue during long-term outdoor handheld inspections. The 3.5-inch high-definition touch screen displays clear and readable images under strong light, and the operation menu is simple and easy to understand. After simple training, operation and maintenance personnel can proficiently operate it. The whole machine has reached the IP54 protection level, with dust, water, and fall resistance, and is suitable for harsh outdoor conditions such as sun, rain, wind, sand, and dust. It is equipped with a large capacity rechargeable lithium battery, and a single battery supports long-term continuous operation, meeting the requirements of all day power station inspection tasks.

In terms of functional configuration, the LX-F300 integrates rich professional temperature measurement tools, supporting point temperature measurement, capturing the highest and lowest temperature in the area, isotherm display, and trend analysis of line temperature measurement. It can intuitively mark the overheating area and quickly locate the fault location. The device has built-in WiFi wireless transmission function, and thermal imaging images and temperature measurement videos can be quickly synchronized to mobile phones and computer terminals. The data collected on site can be shared to the background without copying. It supports video recording, and the video file is fully embedded with all the original temperature data. In the later stage, the video can be traced back in the PC analysis software to conduct temperature measurement analysis again, which is convenient for fault retention and review. At the same time, it supports the issuance of custom inspection task packages, standardizes team inspection work, reduces human errors, and adds location and fault type notes to the collected images, facilitating the establishment of fault ledgers in the later stage and assisting in the digital upgrade of power station operation and maintenance.

In the photovoltaic industry, LX-F300 can be used for rapid inspection of the entire photovoltaic array, screening for local high temperatures caused by component hot spots, hidden cracks, and obstructions; Detect heating faults in combiner boxes, internal wiring terminals of inverters, fuses, and circuit breakers; Check for potential risks of aging, virtual connection, and overheating in AC/DC cable joints. In addition to photovoltaic operation and maintenance, this instrument is also suitable for testing distribution cabinets, inspecting industrial equipment, HVAC testing, and many other fields. In the past, many power stations relied on manual inspection of faults with the naked eye, and a large number of potential heat hazards were difficult to detect. By the time a burning fault occurred, it had already caused significant economic losses. Handheld infrared thermal imaging devices can provide early warning and eliminate faults in the bud stage. Suzhou LAILX adheres to domestic independent research and development, and controls all core software and hardware of LX-F300 independently. Compared with similar overseas products, it has higher cost-effectiveness and complete localized technical support, including operation training, equipment calibration, and free software and hardware upgrade services, to solve various problems encountered by users during instrument use. With the increasing scale of domestic stock photovoltaic power stations and the continuous improvement of safety operation and maintenance pressure, efficient and accurate infrared detection instruments are becoming essential equipment for operation and maintenance teams. The LX-F300 handheld infrared thermal imaging instrument, with its powerful comprehensive performance, provides safe production and navigation protection for the new energy industry, and helps the stable development of the photovoltaic industry.
