Fault identification method of dry type reactor

Abstract

The invention relates to the technical field of fault identification of dry type reactors, and in particular discloses a fault identification method of a dry type reactor, wherein the fault identification method of the dry type reactor comprises the steps of: respectively acquiring a vibration signal of the dry type reactor in a normal state and a vibration signal of the dry type reactor in a fault state; respectively processing the vibration signal in the normal state and the vibration signal in the fault state, so that a processing result is obtained; inputting the processing result into anSOM network, and training the SOM network, so that the trained SOM network is obtained; inputting data to be tested into the trained SOM network, so that an output result is obtained; and judging thefault mode of the dry type reactor according to the output result. By means of the fault identification method of the dry type reactor provided by the invention, the fault of the dry type reactor canbe identified well; furthermore, because the SOM network is an unsupervised self-organizing mapping network, the network scale is small; the learning process time is short; the calculation amount is low; and the trained network has good fault tolerance.

Description

technical field [0001] The invention relates to the technical field of dry-type reactor fault identification, in particular to a dry-type reactor fault identification method. Background technique [0002] With the increase in the number of dry-type reactors in operation and the increase in the number of years of operation, factors such as immature technology or inadequate process control in early products lead to product quality defects gradually appearing. At the same time, because it uses air for heat dissipation and the operating environment is relatively harsh, it is easy to cause insulation damage after long-term operation, further causing faults such as inter-turn short circuit, and even causing reactor burnout in severe cases, which affects the safe and stable operation of the power grid. According to relevant research, 95% of reactor failures are caused by insulation faults and inter-turn short circuits. However, existing monitoring methods have problems such as low ...
