Description
Summary:The thermal resistance temperature measure-ment technique is widely used in the temperature measurement and control systems for dry-type transfor-mers. The infrared temperature measurement technique has been put into practical use. The fiber-optic sensing temperature measurement technique is newly developed and has a good development prospect. All these three kinds of temperature measurement techniques have too low response speed in the temperature measurement and control of dry-type transformers. The prediction temp-erature measurement and control method based on the BP neural network is feasible to increase the response speed.
