Common Fault Diagnosis of Transformers in Nuclear Power Station
Transformers are one of the most important electrical equipment in the power system,responsible for voltage transformation,energy distribution,and transmission.Once an abnormal situation occurs during operation,it will affect the normal operation of the system and the normal power supply to users,and even cause large-scale power outages.In nuclear power plants,large transformers play a crucial role in transmitting power to the external power grid and supplying power to internal loads.Therefore,the normal operation of large transformers is an important guarantee for the safe,reli-able,high-quality,and economical operation of the power system in nuclear power plants,and it is necessary to prevent and reduce transformer failures and accidents to the greatest extent possible.The article introduces some common defects and faults of large transformers,analyzes the causes and treatment methods of these faults,and briefly introduces and an-alyzes a commonly used fault analysis method for transformers-dissolved gas chromatography analysis in oil.
