As a high-voltage electrical system, photovoltaic power plants are exposed to complex outdoor environments for a long time, and are susceptible to erosion from factors such as sun exposure, rain, wind and sand, and humidity. This can easily lead to aging and damage of cable insulation layers, corrosion and failure of grounding devices, and subsequently cause safety accidents such as leakage, short circuits, electric shocks, and lightning strikes, seriously threatening personnel safety and stable equipment operation. The LXH601 insulation and grounding comprehensive tester independently developed by LAILX in Suzhou has the core advantages of integrated design, multi parameter accurate detection, precise fault location, portability, safety and durability. It integrates insulation testing, grounding testing, voltage and current testing, polarity testing, fault location and other functions, becoming the "all-round guardian" of electrical safety testing in photovoltaic power plants, and building a solid defense line for the safe and stable operation of photovoltaic systems.

Electrical safety is the core prerequisite for the stable operation of photovoltaic power plants, and insulation performance and grounding reliability are the two key cornerstones of electrical safety. Traditional photovoltaic power station electrical safety testing relies on multiple single function devices, which are cumbersome to operate, inefficient, have poor data correlation, and difficult to accurately locate insulation fault points. The development of the LAILX LXH601 insulation grounding comprehensive tester has completely broken through the industry's difficulties, integrating multiple core detection functions into one, achieving "one device, full detection, precise positioning, high efficiency and convenience", greatly improving the efficiency and accuracy of electrical safety detection in photovoltaic power plants.

Integrated design with comprehensive and powerful functions. The LXH601 machine covers a full range of electrical safety testing functions, including voltage and current testing, continuity grounding testing, polarity testing, Voc (open circuit voltage), Lsc (short circuit current), insulation resistance testing, insulation fault location, and grounding resistance testing. One device can complete comprehensive safety testing of photovoltaic power station strings, cables, junction boxes, components, and grounding systems without frequent equipment replacement, greatly reducing testing costs and operational complexity. The device supports 1500V high-voltage insulation testing and is compatible with current mainstream 1500V high-voltage photovoltaic systems; The measurement range of insulation resistance is wide and the accuracy is high, which can accurately detect insulation performance degradation caused by insulation layer aging, damage, moisture, etc. The grounding resistance test supports the 2-wire method/3-wire method, with an accuracy of * * ± 2% rdg ± 0.1 Ω (2 Ω range) * *, which can effectively detect issues such as corrosion, looseness, and failure of grounding devices, ensuring the reliability of the grounding system and preventing lightning strikes and electric shock risks.

Accurate detection and fault location, safety hazards are nowhere to be hidden. LXH601 adopts high-precision measurement chips and advanced detection algorithms, with accurate and reliable test data, providing authoritative basis for electrical safety assessment. Its core advantage lies in its precise insulation fault location function, which can accurately locate insulation fault points such as cable damage, junction box water leakage, and component insulation layer damage in photovoltaic systems. It helps operation and maintenance personnel quickly locate the fault location, repair or replace it in a timely manner, greatly reducing system downtime and lowering maintenance costs. At the same time, the equipment can automatically record test data, generate detection reports, facilitate data traceability and full lifecycle security control; Support dual-mode testing (DUAL mode/TIMER mode) to adapt to different detection scenarios and enhance detection flexibility.

Portable, durable, and safe design, suitable for complex outdoor scenes. LXH601 adopts an industrial grade portable design, with a compact and lightweight body, equipped with a high-strength protective box, dust-proof, waterproof and drop proof, suitable for harsh outdoor environments; IP54 dustproof and waterproof design, can be used normally in rainy and dusty weather. The body is equipped with a high-definition LCD large screen with backlight display, which can clearly display data in strong light and dark environments; The operation interface is simple and intuitive, with bilingual switching between Chinese and English, making it easy for beginners to quickly get started. Built in large capacity rechargeable battery, with long-lasting battery life, meeting the needs of long-term outdoor testing; Equipped with automatic discharge function and multiple safety protection designs such as overload protection, reverse connection protection, and high voltage warning, it automatically discharges after testing, providing dual protection for the safety of operators and preventing safety accidents from occurring.

Full scene adaptation, safeguarding the security of the entire photovoltaic industry chain. The LXH601 insulation grounding comprehensive tester can be widely used in photovoltaic power plant construction acceptance, daily operation and maintenance inspection, fault diagnosis and maintenance, component arrival inspection, third-party safety assessment, and renovation and upgrading of old power plants. Whether it is a large-scale ground power station, distributed rooftop power station, agricultural photovoltaic complementary power station, or household photovoltaic system, LXH601 can provide comprehensive and accurate electrical safety testing services, timely discover and eliminate insulation and grounding safety hazards, and ensure the long-term safe, stable, and efficient operation of photovoltaic systems.
