High-sensitivity multi-parameter gas decomposition product long-term monitoring and analyzing system

Abstract

The invention relates to the technical field of gas decomposition monitoring and analysis, in particular to a high-sensitivity multi-parameter gas decomposition product long-term monitoring and analysis system, which comprises a gas collection module, a gas analysis module and a gas analysis module, the gas separation module is used for separating multi-parameter decomposition product gas in the gas sample according to components; the multi-parameter detection module comprises a sensor array, and the sensor array comprises an electrochemical sensor, a photoacoustic spectrum sensor and an infrared absorption sensor; the data processing and analysis module is used for receiving output data of the multi-parameter detection module and carrying out data processing and analysis, and the data processing and analysis specifically comprises decomposition product trend analysis and a fault mode recognition model; and the data storage unit supports storage of long-term operation data. According to the method, the latent fault type of the circuit breaker is automatically identified, and the time change trend of the decomposition product concentration and the ratio is combined to predict the future change of the concentration and the ratio, monitor the abrupt change point and pre-release the potential risk.
