Ao integrar o monitoramento online de umidade SF₆, medição de densidade de gás, e comunicação de dados inteligente, o sistema permite que empresas de serviços públicos e usuários industriais detectem riscos de degradação do isolamento em um estágio inicial e garantam segurança, operação estável de equipamentos de alta tensão.
Visão geral do sistema de monitoramento on-line de umidade de traço de gás SF₆
O gás SF₆ é um meio ideal de isolamento e extinção de arco devido às suas excelentes propriedades elétricas e químicas. No entanto, excessivo rastrear teor de umidade e anormal Densidade do gás SF₆ pode reduzir significativamente a rigidez dielétrica, acelerar o envelhecimento do isolamento, e aumentar o risco de descarga interna e falha do equipamento.
O Sistema de monitoramento on-line de umidade de traço de gás SF₆ mede continuamente os principais parâmetros do gás, incluindo teor de umidade (ppmv), ponto de orvalho, densidade do gás, pressão, temperatura, and relative humidity. O sistema suporta operação on-line sem emissão de gases e fornece, 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, incluindo:
- Trace moisture content (ppmv)
- Dew point temperature (°C)
- Temperatura- 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, centralized data management, and unified alarm processing for multiple measurement points.
The system is suitable for 110 kV para 750 kV voltage levels and is widely applied in SF₆ circuit breakers, SIG, and AIS installations in substations and power plants.
