Technical Specifications for the GIS Micro-Water Density Online Monitoring System, T/CAEE 017-2025

Scope

4 System Composition Basic Composition The GIS Micro-Water Density Online Monitoring System should consist of the following components: a) Sensors: Used to measure the micro-water content and density of SF? gas, temperature, and pressure, they should have high sensitivity, high accuracy, and good anti-interference capabilities. b) Data Acquisition Unit: It should collect sensor signals and convert them into digital signals. c) Data Processing Unit: It should collect data for analysis, processing, and storage. d) Communication Module: It should support wired or wireless communication and transmit data to the monitoring terminal. e) Monitoring Terminal: It should display monitoring data, alarm information, and historical data query. Working Principle ? The monitor is connected to the SF? gas chamber, and the main IED supplies power and handles communication for the monitor. The sensor collects analog signals such as temperature, pressure, and humidity in the high-voltage switch and transmits them via RS485 or fiber optics to the backend user interface, providing real-time data collection and display, data transmission, fault alarm transmission, and backend data analysis. 5 Technical Requirements Environmental Conditions 5.1.1 The system should operate normally under the following environmental conditions: a) Ambient temperature: -40°C to +45°C b) Operating temperature: -40°C to +85°C c) Relative humidity: 5% to 95% d) Atmospheric pressure: 80kPa to 110kPa Appearance Requirements 5.2.1 The appearance should be free from obvious flaws, scratches, paint peeling, or rust. 5.2.2 The connection points of the devices should be tight, and the movable parts should operate smoothly. Performance Requirements 5.3.1 Measurement Range For micro-water content of 0 to 2000ppm and dew point range of -80°C to +20°C, the accuracy of dew point temperature measurement should be better than ±1°C; for micro-water content of 1000 to 2000ppm, the ac
