Electrical safety is the core prerequisite for the stable operation of photovoltaic power plants. Problems such as decreased insulation performance, poor grounding, and line faults can easily lead to safety accidents such as leakage, short circuits, electric shock, and even fires, seriously threatening the safety of power plant equipment and personnel. With the continuous increase in voltage of photovoltaic systems (the popularization of 1500V systems), higher requirements have been put forward for the accuracy, range, and functionality of electrical safety testing equipment. Traditional detection equipment has a single function, complicated operation, and insufficient accuracy, which cannot meet the comprehensive electrical safety detection needs of photovoltaic systems. Suzhou LAILX follows the industry development trend and launches LXH601 insulation grounding comprehensive tester, which integrates multifunctional testing, high-precision measurement, and intelligent analysis, providing a one-stop solution for electrical safety testing of photovoltaic power plants.

LXH601 is a high-performance insulation and grounding comprehensive testing equipment developed by LAILX specifically for photovoltaic power plants and power systems. The whole machine integrates seven core functions, including voltage and current testing, continuity grounding testing, polarity testing, Voc/Isc testing, insulation resistance testing, insulation fault location, and grounding resistance testing. One device can complete the comprehensive electrical safety testing of photovoltaic systems, completely solving the industry pain points of traditional equipment with single functions and the need for multiple devices to cooperate. The device has a testing range of up to 1500V and is perfectly compatible with current mainstream 1000V and 1500V photovoltaic systems. It can meet the electrical safety testing needs from components, inverters to the overall power station, and is widely used in power station installation and acceptance, regular operation and maintenance, fault diagnosis, electrical safety annual inspection and other scenarios.

In terms of measurement accuracy and stability, LXH601 has reached a professional level. It adopts high-precision sampling chips and advanced signal processing technology, with an insulation resistance measurement range of 0.01 Ω~100G Ω, a grounding resistance measurement range of 0.01 Ω~2000 Ω, a voltage measurement accuracy of ± 0.5%, and a resistance measurement accuracy of ± (2%+5d), ensuring that all detection data is accurate and reliable. Equipped with dual testing modes of DUAL and TIMER, it can be freely switched according to different detection needs. DUAL mode achieves fast and accurate measurement, while TIMER mode supports timed testing, suitable for long-term stability testing and aging testing. At the same time, the equipment has automatic range switching, automatic data calibration, and anti-interference filtering functions, effectively eliminating on-site electromagnetic interference and environmental factors, ensuring stable and accurate detection results under complex working conditions.

Intelligent operation and convenient design greatly improve detection efficiency. LXH601 is equipped with a 3.5-inch high-definition color touch display screen, paired with a simple and intuitive graphical user interface, bilingual display in Chinese and English, clear and easy to understand function menus, and can be quickly mastered without professional training. Support one click testing function, after selecting the corresponding testing item, the device automatically completes parameter settings, data collection, result calculation and display, greatly simplifying the operation process. The device adopts a large capacity lithium battery and AC/DC dual power supply design, with a battery life of up to 12 hours, meeting the needs of all day outdoor testing; Simultaneously supporting on-board power supply, suitable for various on-site scenarios.

Data management and fault location functions provide strong support for operation and maintenance. The device has a built-in large capacity memory that can store over 5000 sets of test data, supporting functions such as data viewing, editing, deletion, and export. Equipped with professional data analysis software, the detection data can be transmitted to the computer through USB and Bluetooth, automatically generating standardized electrical safety detection reports including test items, data results, qualification judgments, and time dates. It supports exporting and printing in PDF and Excel formats. Its core advantage is the insulation fault location function, which can accurately locate fault points such as cable damage, junction box water leakage, and component insulation aging in photovoltaic systems, without the need for step-by-step troubleshooting, greatly reducing fault repair time and minimizing power plant shutdown losses.

Outdoor durability and safety protection, fully adapted to the on-site needs of photovoltaics. The whole machine adopts high-strength engineering plastic shell and integrated sealing design, certified with IP65 protection level, waterproof, dustproof, anti drop, earthquake resistant, and can operate stably in harsh outdoor environments such as -20 ℃ to 60 ℃, high humidity, dust, strong electromagnetic interference, etc. The internal circuit adopts multiple safety protection designs, with overvoltage, overcurrent, reverse connection, leakage, and short circuit protection functions. When abnormalities are detected, it automatically shuts down for protection, effectively ensuring the safety of operators and equipment. The overall lightweight and portable design of the device, coupled with a high-strength protective box, can be carried and quickly deployed by a single person, achieving "anytime, anywhere, secure detection".

In terms of application scenarios and industry value, LXH601 covers electrical safety testing throughout the entire lifecycle of photovoltaics. During the construction phase of the power station, component insulation testing, cable grounding testing, and system polarity testing can be conducted to ensure installation quality; During the operation and maintenance phase, regular insulation resistance and grounding resistance tests are conducted to promptly identify potential safety hazards and prevent accidents from occurring; Quickly locate the insulation fault point when a malfunction occurs, achieving efficient repair. At the same time, the equipment is suitable for electrical safety testing in power fields such as substations, distribution rooms, and power equipment, and has a wide range of industry applicability.

Suzhou LAILX LXH601 Insulation Grounding Comprehensive Tester redefines the photovoltaic electrical safety testing standards with its core advantages of "multifunctionality, high precision, intelligence, and strong portability". As the "guardian pioneer" of power plant safety, LXH601 comprehensively ensures the electrical safety of photovoltaic systems, effectively reduces the risk of safety accidents, extends the service life of equipment, and builds a solid defense line for the stable operation and safe production of photovoltaic power plants. In the future, LAILX will continue to deeply cultivate the field of electrical safety testing, continuously innovate technology, optimize products, and provide more professional, reliable, and intelligent safety testing solutions for the photovoltaic and energy industries.
