Description

technical field [0001] The invention relates to the technical field of electrical equipment, in particular to an online rapid detection system for gas content in transformer oil. Background technique [0002] Gas in oil monitoring technology, through the measurement and analysis of dissolved gas in insulating oil, realizes online monitoring of the internal operating status of large transformers, can detect and diagnose internal faults in time, and grasp the operating status of equipment at any time. Recognized as the most effective means of transformer monitoring and diagnosis. The main problems to be solved to realize the real-time monitoring of the transformer by this means are: 1. The dissolved gas in the oil is separated rapidly and completely. 2. Accurate acquisition of concentration data of each gas component. If the sampling time is too long, or the degassing is not complete, it will affect the accuracy of the monitoring data. This device is based on the principle ...
