Application of Micro Water Density Online Monitoring System

Due to its inherent characteristics, gas is currently an ideal insulating and arc extinguishing medium. But its micro water content, gas density, and other factors will have a direct impact on the operation of equipment, personnel safety, and the reliability of the power grid. Therefore, for SF₆The monitoring of micro water content and gas density in electrical equipment has always been an important component of equipment monitoring in related industries. Relevant departments have successively formulated relevant standards for SF₆Strictly control the gas quality, especially the micro water content. The recommended standards of the Ministry of Electric Power, including the "Preventive Testing Code for Power Equipment (DL/T596-1996)", the national standard "Guidelines for Gas Management and Inspection in SF6 Gas Insulated Equipment (GB/T 8905-1996)", and the IEEE standard "IEEE Guide for Moisture Measurement and Control in SF6 Gas Insulated Equipment (IEEE Std 1125-1993)", all adopt the method of controlling moisture in SF₆In the form of gas volume ratio (ppm).

SF₆The online monitoring system for gas micro water density has changed the traditional time-consuming and labor-intensive offline measurement method that pollutes the environment, and can accurately measure SF in real time₆Multiple gas indicators have laid a solid foundation for the intelligent construction of the power grid.
