Product introduction
The oil dissolved gas analyzer is an instrument used to detect the dissolved gas components in transformer oil. The oil dissolved gas analyzer accurately detects the concentration of gases such as hydrogen, carbon monoxide, and methane by extracting, separating, and analyzing the dissolved gases in the oil sample. The oil dissolved gas analyzer is mainly used to detect transformer faults in the power industry at an early stage, because changes in gas concentration can directly reflect the type of internal faults in the transformer. For example, the detection of high concentrations of acetylene may indicate a discharge fault.

Product features
High-precision Gas Detection
The oil dissolved gas analyzer has the high-precision function of detecting trace gases in transformer oil, and its detection accuracy can reach one part per million (ppm). This high-precision feature comes from the instrument's built-in high-sensitivity gas sensor and gas chromatography system, which can effectively identify gases such as hydrogen, methane, and acetylene with extremely low content in the oil. The advantage of this high-precision detection is that it can quickly capture early signals of potential faults when the gas concentration has just changed slightly, allowing maintenance personnel to take preventive measures in time.
Multi-component Gas Separation Technology
The oil-dissolved gas analyzer factory uses a gas chromatography separation column, which can separate different gases such as hydrogen, methane, and carbon monoxide according to the physical properties of the gas, such as positive and negative polarity and molecular weight, and detect the concentration of each gas separately. This can help engineers more accurately identify the type of fault in the transformer. For example, if high concentrations of methane and carbon monoxide are detected at the same time, it may be an oxidation fault inside the equipment. If the concentrations of acetylene and hydrogen are significantly increased, it usually indicates that there may be arc discharge inside the transformer.
Rapid Response Detection
The oil-dissolved gas analyzer manufactures has the characteristics of rapid response detection, and can usually complete the analysis of gas in oil within a few minutes. This is because the gas extraction module uses vacuum extraction technology, which allows the gas to be extracted from the oil and transferred to the analysis unit in a very short time. In addition, the data processing system is equipped with advanced data algorithms and real-time analysis software, so that the gas signal can be quickly analyzed after detection. The advantage of this feature is that it can capture changes in abnormal gas content at the beginning of the transformer state change and alarm in real time, thereby providing engineers with sufficient time to make judgments and handle them.
Intelligent Fault Analysis
The oil dissolved gas analyzer supplier is equipped with an intelligent fault analysis system, which can automatically analyze the detection results and issue an alarm according to the set safety threshold. This function is achieved by establishing a fault model based on a large amount of historical data. When the concentration of a certain gas in the oil is detected to exceed the set threshold, the analyzer will immediately issue an alarm. For example, if the system detects a sharp increase in acetylene concentration, it may mean that there is a high temperature fault or partial discharge problem. The alarm at this time can remind maintenance personnel to check the equipment in time to avoid serious faults.
