1.1 Functional Overview

   NAPZH-5 SF6 gas quality comprehensive analysis and testing device, provides a simple SF6 gas discharge decomposition products on-site detection and fault diagnosis of new methods. The SF6 gas was flowed through the electrochemical sensor at a constant flow rate. The instrument directly measured the content of the main decomposition products of SF6 gas.

  All sensors use the British Alpha sensor, long-life design, to ensure the accuracy and reproducibility of measurement results.

  Main applications: fault location, routine testing, partial discharge monitoring, gas purification / filtration monitoring, fault high voltage contact inspection, SF6 decomposition product detection, check the switch decomposition products.

  The SF6 gas purity, concentration, temperature and humidity in the SF6 electrical equipment are analyzed and analyzed, and the gas quality of the SF6 gas is analyzed and judged by the dew point and the micro water content and the discharge decomposition product gas.
