As a high-voltage electrical system, photovoltaic power plants are exposed to the outdoors for a long time, experiencing wind, sun, rain, snow, frost, and sand erosion. The insulation performance and grounding reliability of their electrical system are constantly facing severe tests. Aging of cables, water leakage in junction boxes, damage to insulation layers of components, loose grounding connections, and other issues can easily lead to a decrease in insulation performance and grounding faults, causing major safety accidents such as leakage, short circuits, electric shock, and fires, seriously threatening personnel safety, stable equipment operation, and power generation revenue of the power station. Regularly conducting safety inspections such as insulation resistance testing, grounding resistance testing, conductivity testing, and voltage testing is the core means of identifying electrical hazards and ensuring the safe operation of power stations. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) is deeply engaged in the field of new energy testing. Based on years of technological accumulation and the advantages of industry university research cooperation, we have launched the LXH601 comprehensive insulation and grounding tester. With integrated design, high-precision testing, and intelligent operation, it solves the pain points of traditional testing, provides professional solutions for the safe operation and maintenance of photovoltaic power plants, and builds a solid defense line for the safety of the new energy industry.

Traditional photovoltaic power station electrical safety testing relies heavily on single function testing equipment, such as insulation resistance testers, grounding resistance testers, conductivity testers, voltmeters, etc., which need to be carried separately and frequently switched wiring, making the operation cumbersome and the testing efficiency low. At the same time, traditional equipment has weak anti-interference ability, and its detection accuracy is easily affected in complex outdoor electromagnetic environments. It also has a single function and cannot simultaneously complete multiple key detections, making it difficult to meet the safety detection needs of photovoltaic power plants in all scenarios. In addition, some devices are bulky and have poor portability, which cannot meet the detection needs of complex outdoor scenes such as mountains, deserts, and rooftops, seriously restricting the safety and operation efficiency of power plants. In response to industry pain points, LAILX LXH601 insulation grounding comprehensive tester has made innovative breakthroughs, integrating multiple core functions into one, achieving "one machine for multiple purposes, integrated detection", greatly improving operation and maintenance efficiency and detection accuracy.

Integrated with multiple functions, significantly improving operational efficiency. LXH601 breaks the limitations of traditional testing equipment with "one machine, one use", integrating core functions such as insulation resistance testing, grounding resistance testing, conduction testing, voltage detection, polarity testing, Voc/Lsc testing, and insulation fault location. It does not require frequent switching of equipment and wiring, and can complete multiple key tests in one operation, completely solving the problem of operation and maintenance personnel carrying multiple instruments back and forth for work. The efficiency of a single inspection has been improved by over 40%, significantly reducing labor and time costs, and adapting to the large-scale safety testing needs of photovoltaic power plants. The device supports bipolar mode detection and can simultaneously measure the insulation resistance of the positive and negative poles of the circuit to ground, accurately evaluating the insulation status of the device; Equipped with polarity testing function, it can quickly determine whether the circuit polarity is correct, avoiding safety accidents caused by reverse connection. At the same time, it can accurately measure the open circuit voltage (Voc) and short-circuit current (Lsc) of photovoltaic modules, synchronously complete electrical safety testing and module performance evaluation, and achieve integrated testing of "safety+performance".

High precision detection performance ensures accurate and reliable data. LXH601 adopts self-developed high-precision testing module, with a wide range of insulation resistance measurement and an accuracy of ± 1%. It can accurately detect the insulation performance of photovoltaic modules, inverters, combiner boxes, cables and other equipment, and timely detect hidden dangers such as insulation aging, damage, and moisture. The measurement accuracy of grounding resistance reaches ± 2%, which can accurately evaluate the reliability of the grounding system, troubleshoot faults such as loose grounding connections and corroded grounding electrodes, ensure effective discharge of fault currents from the grounding system, and guarantee the safety of personnel and equipment. The equipment has strong anti-interference ability and adopts shielding design and filtering technology to effectively resist outdoor complex electromagnetic environment interference, ensuring the accuracy and stability of detection data under different working conditions. At the same time, the built-in insulation fault location function can accurately locate the insulation fault points in the photovoltaic system, such as cable damage, junction box leakage, etc., helping operation and maintenance personnel quickly locate the fault location, reduce system downtime, and improve operation and maintenance efficiency.

Portable and durable design, suitable for complex outdoor scenes. LXH601 adopts a compact integrated design, with a sturdy and durable structure, light weight, and is equipped with a high-strength protective box, which is earthquake resistant and drop resistant, making it easy to carry and transport. Whether it is a rugged mountain power station, a vast desert power station, or a space limited rooftop distributed power station, operation and maintenance personnel can easily carry equipment and quickly arrive at the testing site, without the need for complex installation and commissioning. It can be used out of the box, greatly reducing the difficulty of outdoor operations. The equipment adopts industrial grade protection design, dustproof and moisture-proof, and can adapt to long-term stable operation in harsh outdoor environments, ensuring the continuity of testing work. In terms of battery life, it is equipped with a large capacity lithium battery, which can support continuous detection for more than 8 hours on a single charge, without relying on external power sources, and is suitable for the detection needs of remote power stations and scenarios without power supply.

Intelligent operation and data management help upgrade the intelligence of operations and maintenance. LXH601 is equipped with a high-definition color touch screen, with a simple and intuitive interface in both Chinese and English, clear functional layout, and easy operation for beginners without professional training. The device is equipped with a built-in database of electrical safety testing standards for photovoltaic power stations, which supports one click selection of testing items, automatic matching of testing parameters, and reduces the tedious operation of manual settings. After the detection is completed, the detection report can be exported in PDF or Excel format with one click, supporting multiple methods such as USB direct transmission and wireless transmission, making it convenient for data archiving, sharing, and tracing. At the same time, the device has data storage function, which can automatically record each detection data, form operation and maintenance files, facilitate subsequent data comparison and analysis, timely discover changes in insulation performance and grounding resistance trends, warn potential hazards in advance, and achieve the transformation from "passive maintenance" to "active prevention" operation and maintenance mode.

With excellent performance and wide adaptability, the LXH601 insulation grounding comprehensive tester has been widely used in photovoltaic power plant acceptance, daily operation and maintenance, fault diagnosis, safety annual inspection and other scenarios. During the acceptance stage of the power station, the insulation performance and grounding reliability of the electrical system can be comprehensively tested to eliminate safety hazards and ensure the quality of power station construction; In daily operation and maintenance, regular safety inspections are conducted to promptly identify and address hidden dangers such as insulation aging and grounding faults, ensuring the long-term safe and stable operation of the power station; In troubleshooting, it is possible to quickly locate the location of electrical faults, shorten downtime for maintenance, and reduce the loss of power generation revenue.
