Three overheat protection system for dry-type transformer are introduced: Contact thermal resistance overheat protection system, Infrared overheat protection system, Fiber-optic sensing overheat protection system. The thermal resistance overheat protection system and infrared overheat protection system are widely used. The temperature measurement technology, work theories, characteristics, applying objects are analyzed.The response speed of all these three kinds of overheat protection system was too low. The prediction control method based on the BP neural network is feasible to increase the response speed of overheat protection system for dry-type transformer.
