As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments such as sun exposure, rain, humidity, and sandstorms for a long time. The insulation layer of the cables is prone to aging and damage, the junction box is prone to water leakage, and the grounding device is prone to corrosion and failure, which can lead to safety accidents such as leakage, short circuit, electric shock, and lightning strikes, seriously threatening personnel safety and the stable operation of the power plant. Traditional testing equipment has a single function, complicated operation, and weak anti-interference ability, requiring multiple instruments to be carried back and forth for operation, making it difficult to meet the electrical safety testing needs of photovoltaic power plants in all scenarios. Suzhou Laikesi New Energy Technology Co., Ltd. (LAILX) has launched the LXH601 Insulation and Grounding Comprehensive Tester, which provides a one-stop solution for insulation and grounding safety testing in photovoltaic power plants with integrated design, high-precision detection performance, and intelligent operation experience, safeguarding the safe and efficient development of the photovoltaic industry.

LXH601 breaks the traditional limitation of "one machine, one use" for devices, achieves multifunctional integration, and greatly improves the efficiency of operation and maintenance testing. The equipment integrates more than 10 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 electrical safety testing of key equipment such as photovoltaic power plant components, inverters, combiner boxes, and cable lines in one operation. It completely solves the problem of operation and maintenance personnel carrying multiple instruments to and from work, and improves the efficiency of single inspection by more than 40%. 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 insulation fault location function, it can quickly lock insulation fault points such as cable damage and junction box water leakage, helping operation and maintenance personnel to accurately repair and reduce system downtime.

High precision detection performance and strong anti-interference ability, suitable for complex outdoor detection scenarios. LXH601 adopts LAILX's self-developed high-precision testing chip, with an insulation resistance testing range of 1M Ω -100G Ω and a grounding resistance testing range of 0-100 Ω. All testing accuracies are better than ± 1%, which can accurately capture small insulation abnormalities and grounding hazards, providing reliable data support for electrical safety assessment. In response to the complex outdoor electromagnetic environment of photovoltaic power plants, the equipment adopts electromagnetic shielding design and anti-interference algorithms to effectively avoid on-site electromagnetic signal interference, ensure stable and accurate test data, and avoid misjudgments and omissions. The device supports wide voltage input and can adapt to the testing needs of photovoltaic systems below 1500V, covering mainstream distributed photovoltaic and large-scale ground power station scenarios.

Intelligent operation and portable design reduce the threshold and labor intensity of homework. LXH601 is equipped with a high-definition touch color screen, with a simple and intuitive operation interface, fully Chinese menu guidance, support for one click automatic detection, real-time data display, and intelligent result judgment. Novices can quickly get started without professional training. The device has data storage and export functions, which can automatically record each test data and support USB one click export, making it convenient for later data traceability, report generation, and quality analysis. The whole machine adopts a lightweight and portable design, with a sturdy and durable body. It is equipped with a dedicated protective box, which can adapt to harsh outdoor environments. It can be easily carried to the power plant site by a single person without complex installation and debugging, and can be used out of the box. At the same time, the device is equipped with an intelligent protection mechanism that can automatically determine the grounding status. When the grounding is not qualified, it is prohibited to start the detection, avoiding data errors caused by grounding hazards from the source and ensuring testing accuracy.

Strict quality control and full cycle service ensure the long-term stable operation of equipment. LXH601 follows LAILX's strict quality standards from research and development, production to factory testing. The core components are equipped with industrial grade configurations and undergo multiple rounds of high and low temperature, vibration, and waterproof testing to ensure long-term stable operation of the equipment in complex outdoor environments. At present, LXH601 has been widely used in major photovoltaic power plants, operation and maintenance companies, and third-party testing institutions in China, covering all scenarios such as photovoltaic power plant acceptance, daily operation and maintenance, and fault diagnosis. With integrated functions, high-precision performance, and convenient operating experience, it has become the preferred equipment for photovoltaic electrical safety testing.

Electrical safety is the core prerequisite for the stable operation of photovoltaic power plants, and insulation and grounding performance are the two key cornerstones of electrical safety. The Suzhou LAILX LXH601 Insulation Grounding Comprehensive Tester solves traditional equipment pain points with an integrated design, ensures testing quality with high-precision detection performance, and improves operational efficiency with intelligent and portable design. It provides a comprehensive and one-stop detection solution for electrical safety in photovoltaic power plants. In the future, LAILX will continue to deeply cultivate the field of photovoltaic electrical safety testing, focus on industry pain points, increase research and development investment, and launch more high-performance and highly adaptable safety testing equipment to help the photovoltaic industry build a solid safety defense line and achieve safe, healthy, and sustainable development.
