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. Insulation aging, damage, poor grounding, and other issues not only lead to system leakage and efficiency decline, but also may cause major safety accidents such as personal electric shock, equipment burnout, and even fire.

Traditional testing tools have pain points such as cumbersome operation, single functionality, weak anti-interference ability, and low data accuracy. During operation and maintenance, multiple devices need to be carried back and forth for frequent switching of wiring, which is inefficient and prone to errors. It is difficult to meet the safety testing needs of photovoltaic power plants in all scenarios with high precision and efficiency. Suzhou LAILX has been deeply involved in the field of new energy testing for many years. Relying on its profound technological accumulation and advantages in industry university research cooperation, it has launched the LXH601 comprehensive insulation and grounding tester. With integrated design, high-precision testing, and intelligent operation, it provides professional solutions for the safe operation and maintenance of photovoltaic power plants, strengthens the electrical safety defense line of photovoltaic systems, and empowers operation and maintenance to improve quality and efficiency.

Integrated multifunctional integration, solves traditional testing pain points, and greatly improves operation and maintenance efficiency. LXH601 breaks the limitations of traditional testing equipment with "one machine, one use", integrating more than ten core functions such as insulation resistance testing, grounding resistance testing, conduction testing, AC/DC 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 to and from work. The efficiency of a single inspection is increased 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 polarity automatic recognition function to avoid testing errors caused by wiring errors; The insulation fault location function can accurately locate the fault points such as cable damage, junction box water leakage, and component insulation layer damage in the photovoltaic system, helping operation and maintenance personnel quickly and accurately identify hidden dangers and reduce system downtime. Whether it is photovoltaic modules, inverters, combiner boxes, cable lines, or grounding grids and grounding down conductors, LXH601 can efficiently complete detection tasks and achieve "one device, full scene coverage".

High precision detection and strong environmental adaptability ensure accurate and reliable data in complex scenarios. LXH601 adopts high-precision testing chips and intelligent anti-interference algorithms to effectively shield outdoor complex electromagnetic environment interference, ensuring accurate and stable test data. The insulation resistance test range covers 0-10G Ω, and the test voltage can be selected from 500V/1000V/2500V. It is suitable for insulation detection needs of different voltage levels in photovoltaic systems, with a testing accuracy of up to ± 5%; The grounding resistance test range is 0-100 Ω, with an accuracy of ± 2%. It can accurately measure the grounding resistance values of the grounding grid and grounding down conductors, ensuring the reliability and effectiveness of the grounding system. The equipment has the ability to work in a wide temperature range and can operate stably in extreme temperature environments ranging from -20 ℃ to 60 ℃. It has excellent dust, water, and earthquake resistance, and is suitable for various complex photovoltaic power plant scenarios such as mountains, roofs, and water surfaces. It is not afraid of outdoor harsh environmental tests. At the same time, the device is equipped with an intelligent temperature compensation module that can automatically correct the impact of temperature changes on test data, further improving detection accuracy and ensuring consistency and reliability of test data under different environmental temperatures.

Intelligent operation and portable design, balancing usability and practicality. LXH601 is equipped with a high-definition color LCD display screen, a simple and intuitive Chinese intelligent operation interface, clear and easy to understand function menus, and dual operation modes of physical buttons and touch screen. Novices can quickly get started without professional training. The device supports one click automatic detection, without the need for complex parameter settings. It can enter testing mode immediately upon startup, greatly reducing the operating threshold; Equipped with automatic data storage, query, and export functions, it can store tens of thousands of sets of test data and support USB interface data export. Paired with supporting data analysis software, it can complete data organization, report generation, trend analysis, and other tasks on the PC side, making it easy to retain, trace, and manage detection data. In terms of portable design, the equipment adopts a lightweight and integrated structure, with a lightweight body and a dedicated portable protective box, making it easy to carry to various work sites; Equipped with a large capacity rechargeable lithium battery, it has strong endurance and can meet all day outdoor testing needs. It supports external power supply and is suitable for long-term continuous operation scenarios.

Full cycle security protection, covering the entire lifecycle operation and maintenance needs of photovoltaic power plants. During the construction phase of the power station, LXH601 can be used for insulation and grounding acceptance testing of electrical equipment installation, ensuring that the installation quality meets safety standards and eliminating safety hazards from the source. In daily operation and maintenance, regular use of LXH601 for insulation and grounding testing of photovoltaic systems can promptly detect issues such as insulation aging, damage, and excessive grounding resistance. Maintenance measures can be taken in advance to prevent safety accidents such as leakage, short circuit, and electric shock, ensuring stable operation of the power station and personnel safety. In troubleshooting scenarios, the equipment can quickly locate insulation and grounding faults, assisting operation and maintenance personnel in precise maintenance, reducing system downtime, and minimizing power generation losses. During the technical renovation and expansion phase of the power station, it can be used for insulation and grounding compatibility testing between newly added equipment and the existing system, ensuring the safe and stable operation of the system after the technical renovation.
