Product details
◆
The updated national standard "Guidelines for Analysis and Determination of Dissolved Gases in Transformer Oil" issued by the National Quality Supervision Administration states that the gas production principle of transformer insulation oil is due to the decomposition of insulation oil and solid insulation materials under electrical and thermal effects. Low energy discharge faults lead to weaker C-H bond breakage, mainly resulting in the reformation of hydrogen gas, while ethylene is generated at temperatures higher than methane and ethane. A large amount of acetylene is generated in the arc path of the arc.
The standard defines "characteristic gases that are valuable for determining internal faults in oil charging electrical equipment, namely hydrogen (H2), methane (CH4), ethane (C2H6), ethylene (C2H4), acetylene (C2H2), carbon monoxide (CO), and carbon dioxide (CO2)", and states that oxygen (O2) and nitrogen (N2) can be used as auxiliary judgment indicators.
Due to the periodic analysis of dissolved gases in laboratory oil at certain intervals, it can detect faults with long latent periods and slow development inside transformers. However, for rapidly developing or even sudden malfunctions, it is often difficult to respond in a timely manner and prevent such accidents from occurring.
The portable equipment for detecting dissolved gases in transformer oil was developed to compensate for the shortcomings of laboratory periodic analysis. Because even if there is a sudden malfunction, there is a time process of occurrence and development, which can prevent the occurrence of so-called sudden accidents to a greater extent.
By adopting updated microcalorimetry technology and components, various challenges such as environmental changes, instrument temperature control, signal interference, and mechanical vibration have been overcome, successfully achieving on-site detection of six types of fault gases and micro water in transformer oil. It can directly perform manual sampling at the transformer site, inject 50ml of oil sample into the testing equipment, and follow the instructions in the operation manual to complete the testing within 20 minutes. Compared to other manufacturers in the same industry, this product has a dual advantage in both price and performance. At the same time, this product can also be designed as an online monitoring system product, providing users with diverse choices and effectively ensuring the safe operation of equipment.
The MOEN-6980 portable oil chromatography analyzer for dissolved gases in oil only requires one chromatographic column to detect 7 types of fault gases in transformer oil, and only one carrier gas is needed. The instrument integrates a miniature carrier gas cylinder inside. Compared with traditional transformer chromatography analyzers, the instrument not only has greatly improved performance, but also has a greatly reduced volume. Compared with laboratory equipment, this equipment has better consistency, sensitivity, and accuracy, meeting the requirements of GB/T17623-1998 "Gas Chromatography Determination of Dissolved Gas Components in Insulation Oil", GB/T7252-2001 "Guidelines for Analysis and Determination of Dissolved Gas in Transformer Oil", and DL/T703-1999 "Gas Chromatography Determination of Gas Content in Insulation Oil" standards. The main features of this product are easy to carry and use, high utilization rate, reduced operation and maintenance costs, and significant role in ensuring the safe operation of the product.
