The Точка росы газа SF₆ в режиме онлайн & Система мониторинга плотности is designed for continuous, real-time monitoring of trace moisture content, dew point temperature, and gas density in SF₆-insulated electrical equipment. It is widely used in GIS, АИС, and SF₆ circuit breakers, providing reliable data support for condition-based maintenance, управление активами, and smart grid applications.
By integrating online SF₆ moisture monitoring, gas density measurement, and intelligent data communication, the system enables utilities and industrial users to detect insulation degradation risks at an early stage and ensure safe, stable operation of high-voltage equipment.
SF₆ Gas Trace Moisture Online Monitoring System Overview
SF₆ gas is an ideal insulating and arc-quenching medium due to its excellent electrical and chemical properties. Однако, excessive trace moisture content and abnormal SF₆ gas density can significantly reduce dielectric strength, ускорить старение изоляции, and increase the risk of internal discharge and equipment failure.
The SF₆ Gas Trace Moisture Online Monitoring System continuously measures key gas parameters, including moisture content (ppmv), dew point, gas density, давление, температура, and relative humidity. The system supports online operation without gas emission and provides long-term, stable monitoring for SF₆ electrical apparatus.
Online SF₆ Dew Point and Moisture Measurement Principle
The system adopts high-stability trace moisture sensing technology combined with an internal gas circulation sampling method. Water vapor content in SF₆ gas is measured in real time and converted into multiple engineering values, включая:
- Trace moisture content (ppmv)
- Dew point temperature (°С)
- Температура- and pressure-compensated gas density
Built-in intelligent temperature and pressure compensation algorithms effectively eliminate environmental influences, ensuring accurate and repeatable measurement results under varying operating conditions.
Integrated SF₆ Gas Density and Moisture Monitoring Solution
Unlike standalone dew point analyzers or mechanical density gauges, этот integrated SF₆ gas density and moisture monitoring solution combines multiple sensing functions into a unified online system. It enables synchronized monitoring, centralized data management, and unified alarm processing for multiple measurement points.
The system is suitable for 110 кВ до 750 кВ voltage levels and is widely applied in SF₆ circuit breakers, ГИС, and AIS installations in substations and power plants.
