Abstract:

Abnormal changes in temperature and load current of high-current switchgear may lead to equipment defects and affect normal operation.In order to effectively monitor the temperature of the switchgear,the Ansoft electro-thermal simulation module is used to analyze the temperature field changes of key components in the switchgear.The data of temperature changes under different environmental conditions is obtained.The relationship between the temperature sensor and the distance and position of the hot spot is mastered.Finally,the temperature load curve under different current is obtained through the test.The accuracy of the research results is verified by combining the neural network prediction method with the field test.The results can provide the guidance for the on-site operation and maintenance personnel of the substation to install the temperature sensor.

Key words: high-current switchgear, temperature sensors, neural network simulation, temperature rise experiment
