را نقطه شبنم گاز SF₆ آنلاین & سیستم مانیتورینگ تراکم 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, AIS, and SF₆ circuit breakers, providing reliable data support for condition-based maintenance, مدیریت دارایی, 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. با این حال, excessive trace moisture content and abnormal چگالی گاز SF6 can significantly reduce dielectric strength, accelerate insulation aging, and increase the risk of internal discharge and equipment failure.
را SF₆ Gas Trace Moisture Online Monitoring System continuously measures key gas parameters, including moisture content (ppmv), dew point, gas density, فشار, دما, و رطوبت نسبی. 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, از جمله:
- Trace moisture content (ppmv)
- Dew point temperature (درجه سانتی گراد)
- دما- 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, this integrated SF₆ gas density and moisture monitoring solution combines multiple sensing functions into a unified online system. It enables synchronized monitoring, مدیریت متمرکز داده ها, و پردازش زنگ یکپارچه برای چندین نقطه اندازه گیری.
سیستم مناسب برای 110 کیلو ولت به 750 کیلوولت سطوح ولتاژ و به طور گسترده در قطع کننده های مدار SF6 استفاده می شود, GIS, و نصب AIS در پست ها و نیروگاه ها.
