Problems solved by technology

At present, most of the diagnosis methods for reactors are based on Dissolved Gas Analysis (DGA) method. Although this method is simple to implement, the accuracy is not high, and the detection results are one-sided.
With the continuous advancement of science and technology, the immune recognition algorithm is introduced into the health diagnosis of reactors. Although the traditional immune recognition algorithm can respond quickly to the state of the reactor, it cannot effectively control the number of detectors.
