HNPSE1000 Transformer Oil Chromatogram
Overview
The HNPSE1000 transformer oil chromatogram online monitoring system can realize automatic quantitative cycle cleaning, oil intake, oil-gas separation, sample analysis, data processing and real-time alarm; it can online monitor the content of fault gases dissolved in oil of oil-immersed type high-voltage electric equipment such as transformer and its growth quickly, and forecast the equipment fault risk information at early stages through the fault diagnosis expert system to avoid equipment accidents and reduce heavy losses, thus improving the reliability of equipment operation. As a new generation product in the field of oil chromatogram online monitoring, the system will provide stable and reliable solution for realizing online remote DGA analysis of the power transformer, which is the powerful guarantee for implementation of status inspection and repair system of the power system.
Main Features
Online monitoring of concentration parameter and growth rate of H2, CO, CO2, CH4, C2H4, C2H6, C2H2 and micro-water, etc.; (N2 and O2 can be monitored when Argon is carrier gas) quantitative cleaning cycle sampling method to really reflect the status of gases dissolved in transformer oil;
Safe and reliable oil-gas separation without pollution to eliminate bubbles in oil sample re-injected to the transformer body, and multi-layer insulated oil re-injection (oil return) technology to guarantee that the carrier gas will not be taken into the transformer body;
Mature and reliable communication mode and standard network protocol to support remote data transmission;
High data acquisition reliability, and oversampling technology Δ - ∑ analog-digital converter with 24-bit resolution and automatic calibration; improved tri-ratio method, David triangulation method and cube diagram to give diagnosis results; various data display and query mode to provide reports and trend charts, with 10-year storage life of historical data;
With modular design and high performance embedded processor, suitable for a variety of working environment;
