As a high-voltage electrical system, electrical safety is the core prerequisite for ensuring the safety of personnel, stable operation of equipment, and long-term reliable power generation in photovoltaic power plants. Photovoltaic systems exposed to outdoor environments for a long time are susceptible to environmental erosion such as sun exposure, rain, wind and sand, humidity, salt spray, etc. The insulation layer of cables is prone to aging and damage, junction boxes are prone to water leakage, and component insulation performance is prone to decline, which can easily cause safety hazards such as leakage, short circuit, electric shock, and grounding faults. Regular professional insulation and grounding testing is a necessary means to identify electrical hazards and prevent safety accidents. Suzhou LAILX has ingeniously launched the LXH601 Insulation and Grounding Comprehensive Tester, which integrates multiple functions such as insulation testing, grounding testing, voltage and current testing, and fault location. With precise, comprehensive, and convenient performance, it provides electrical safety protection for photovoltaic systems. Lex

LXH601 is a comprehensive testing equipment developed by Lex specifically for electrical safety testing of photovoltaic power plants. It strictly follows international and domestic standards such as IEC, EN61557, EN62446, etc., and integrates core functions such as insulation resistance testing, grounding resistance testing, continuity testing, polarity testing, Voc/Lsc testing, and insulation fault location. One device can complete the comprehensive electrical safety testing of photovoltaic systems, completely solving the industry pain points of traditional equipment with single functions, requiring multiple devices to cooperate, and complicated operation. It is an essential tool for power plant construction, acceptance, operation and maintenance, and electrical safety testing.

Precision and reliability are the core qualities of LXH601. The equipment adopts industrial grade high-precision measurement modules, and the insulation test voltage covers multiple adjustable levels of 500V/1000V/1500V, perfectly adapting to 1500V high-voltage photovoltaic systems. It can accurately measure the insulation resistance between the positive and negative poles of the photovoltaic string to ground and between the positive and negative poles, with a wide measurement range and high accuracy, reflecting the insulation performance of the system in reality. The grounding resistance test adopts advanced measurement principles to accurately detect the grounding resistance value of the grounding body, ensuring the reliability and effectiveness of the grounding system. At the same time, the equipment can accurately measure AC/DC voltage and current, conduct tests on conductor continuity, polarity, etc., and comprehensively evaluate the quality and safety status of electrical system connections.

Intelligent and convenient design greatly improves the detection efficiency of LXH601. The device is equipped with a high-definition LCD display screen, with a simple and clear interface, intuitive data display, support for bilingual switching between Chinese and English, and easy to operate and understand. Innovative DUAL mode and TMR mode dual testing mode: DUAL mode can automatically measure the insulation resistance of the positive and negative poles of the component to ground in sequence, completing dual testing with one click; TMR mode supports continuous timed measurement and long-term stable data collection, ensuring accurate and reliable measurement results under complex working conditions. The device is equipped with intelligent algorithms that can automatically determine whether the test results are qualified, automatically prompt abnormal data, and reduce manual judgment errors. Lex

In response to the complex working conditions of photovoltaic sites, LXH601 has a powerful insulation fault location function, which can accurately locate fault points such as cable damage, junction box water leakage, and component insulation damage in photovoltaic systems, without the need for step-by-step troubleshooting, greatly reducing fault search time, minimizing system downtime losses, and making operation and maintenance more efficient and accurate. At the same time, the device supports automatic data storage and one click export functions, which can store massive test data, generate standardized testing reports, facilitate data archiving, comparative analysis, and compliance acceptance, and meet the electrical safety data management needs of the power plant throughout its lifecycle.

In terms of outdoor practicality and durability, LXH601 performs excellently. The whole machine adopts a lightweight and high-strength protective body design, which is dustproof, waterproof, and anti drop, suitable for a wide temperature working environment of -10 ℃ to 50 ℃, and is not afraid of harsh conditions such as sandstorms, humidity, and dust. It is stable and reliable outdoors. The device is equipped with a large capacity rechargeable lithium battery, which has strong endurance and meets the needs of on-site testing throughout the day, without the need for frequent charging; Equipped with a dedicated portable case for easy carrying, transportation, and storage, it can be easily carried by a single person to various scenarios such as rooftops, mountains, deserts, etc. for testing, truly achieving "anytime, anywhere, efficient testing".
