As a high-voltage direct current electrical system, photovoltaic power plants are exposed to outdoor humid, sandy, and corrosive environments for a long time. Problems such as cable insulation aging and poor grounding can easily cause safety accidents such as leakage, short circuits, and fires, threatening the stable operation of the power plant and personnel safety. Traditional testing equipment has a single function, requiring multiple instruments to cooperate for insulation testing, grounding testing, and voltage detection. It is cumbersome to operate, inconvenient to carry, has low detection efficiency, and weak anti-interference ability, making it difficult to meet the safety testing needs of photovoltaic power plants in all scenarios. LAILX in Suzhou focuses on the core pain points of photovoltaic electrical safety and has launched the LXH601 comprehensive insulation and grounding tester. With the core advantages of integrated integration, high-precision detection, intelligent operation, portability and durability, LAILX creates an integrated solution for photovoltaic electrical safety testing, providing protection for the safe operation and maintenance of photovoltaic power plants. Multi functional comprehensive electrical appliance

The core innovation of LXH601 insulation grounding comprehensive tester lies in its multifunctional integrated design, completely breaking the limitations of traditional equipment's "one machine, one use" approach. The equipment integrates core functions such as insulation resistance testing, grounding resistance testing, conduction testing, AC/DC voltage testing, polarity testing, and insulation fault location. It does not require frequent switching of instruments and wiring, and can complete multiple key tests in one operation, greatly simplifying the operation and maintenance process. The efficiency of a single inspection is increased by more than 40%. For the design of 1500V high-voltage system in photovoltaic power plants, the insulation resistance test range covers 0-1500V, which can accurately measure the insulation resistance of components, inverters, combiner boxes, cables and other equipment, effectively detect insulation aging, damage, moisture and other problems, and prevent leakage accidents. The grounding resistance test supports four pole method measurement, which can accurately evaluate the reliability of the power station grounding system, ensure the rapid discharge of fault current, and guarantee the safety of personnel and equipment.

High precision detection and intelligent fault location make safety hazards nowhere to hide. The equipment adopts high-precision sampling circuit and anti-interference optimization design, which can stably output accurate data in strong electromagnetic interference environment. The insulation resistance testing accuracy is high, and the grounding resistance testing error is small, ensuring the authenticity and reliability of the detection results. Equipped with intelligent insulation fault location function, it can accurately locate the fault points such as cable damage, junction box water leakage, component insulation failure, etc., without the need for step-by-step troubleshooting, greatly reducing the troubleshooting time and minimizing system downtime losses. Simultaneously supporting bipolar mode detection, it can simultaneously measure the insulation resistance of the positive and negative poles of the circuit to ground, and comprehensively evaluate the insulation status of the equipment; Equipped with polarity automatic recognition function, it avoids detection errors caused by wiring errors and improves operational safety.

Portable, durable, and intelligent operation, suitable for complex outdoor operation and maintenance scenarios. The equipment adopts a lightweight and compact design, with a small overall volume and light weight, and is equipped with a portable protective box. It can be easily carried to the power plant site by a single person without relying on large transportation vehicles, and is suitable for complex working conditions such as mountains, roofs, and deserts. On the operational level, it is equipped with a high-definition LCD display screen, a simple and intuitive Chinese menu, and supports one click start detection, which can be quickly mastered without professional training; Built in intelligent data processing system, automatically calculates key parameters and generates detection results after detection, supports data storage, query, and export, and facilitates data archiving and traceability. The body adopts industrial grade protective design, with dust-proof, moisture-proof, and shockproof characteristics, and can operate stably in extreme temperature environments ranging from -10 ℃ to 50 ℃, easily coping with harsh outdoor weather.

In the actual operation and maintenance of photovoltaic power plants, the LXH601 insulation grounding comprehensive tester plays an irreplaceable role. During the daily operation and maintenance phase, regular insulation and grounding inspections can be carried out to promptly identify potential safety hazards, achieve early detection and handling, and avoid small hazards causing major accidents; During the troubleshooting phase, it is possible to quickly locate fault points such as insulation damage and poor grounding, guide operation and maintenance personnel to carry out precise repairs, shorten downtime, and reduce power generation losses; During the acceptance stage of the power station, the safety performance of the electrical system can be comprehensively tested to ensure that the power station meets safety standards and smoothly connects to the grid for power generation. In addition, the equipment is equipped with professional data analysis software, which can perform statistical analysis and trend analysis on the detection data, providing data support for optimizing the operation and maintenance strategy of the power station, and helping the power station achieve intelligent and refined safety management.
