GIS contact temperature computing method with shielding case structure based on infrared sensing

The invention discloses a GIS contact temperature computing method with shielding case structure based on infrared sensing, and the method comprises the steps as follows: having GIS device temperature raising test under different environment temperature conditions, guiding the current for the GIS device, when the temperature distribution gets to the stable state, recording the environment temperature, GIS contact temperature and shielding case temperature; taking the data detected by the GIS temperature raising test as the learning sample, using BP neural network algorithm for computing the GIS contact temperature according to the environment temperature and shielding case temperature. The GIS contact temperature computing method has the effect as follows: the existing infrared temperature online monitoring technology is combined with the data fitting prediction algorithm for solving the problem that the GIS contact temperature cannot be measured via the infrared temperature online monitoring technology for the shielding case, the method is simple and effective and easy to be realized.
