LH600 Early Electric Power Environment Gas Intelligent Monitoring Device Introduction: Human daily life and various tasks are inseparable from electricity, which is one of the major characteristics of human activities in the new century. Therefore, ensuring power supply and electricity safety has always been highly concerned by the power sector and industrial and mining enterprises. More than 99% of electrical equipment widely distributed on the distribution line, such as high and low voltage switchgear, ring main unit, switching stations, box transformers, secondary switchgear, etc., use air insulation. In the early stages of catastrophic failures, these electrical equipment will inevitably undergo corresponding changes in the gas state in their relatively enclosed electrical environment. For example, overheating and smoldering will produce smoke particles, leading to an increase in air shading and CO concentration. An increase in humidity will exacerbate air ionization, and electric field concentration, surface discharge, partial discharge, etc. will cause air ionization, leading to an increase in ozone concentration, and so on. The LH600 early electric power environment gas intelligent monitoring device is specifically designed for real-time monitoring of the above changes, and through wired or wireless data transmission, it timely sends the state information and warning information of the electric power environment gas to users, facilitating users to make correct predictions and processing in advance, avoiding major electric power safety accidents or reducing accident losses. Features: 1. Based on the most advanced smoke particle dual light source photoelectric detection technology, provide early warning for extremely early electrical fires; 2. Real time monitoring of carbon monoxide content, providing early warning for electrical hazards including overheating or high-temperature smoldering; 3. Real time monitoring of ozone content, providing extremely early warning for electrical insulation faults such as abnormal air ionization and various micro discharges; 4. Real time monitoring of temperature and humidity facilitates comprehensive prediction of equipment status; 5. Real time data transmission can be achieved through wired or IoT technology.
