    Abstract: This article aims to conduct an in-depth analysis of the operating principle, signal interpretation, inspection criteria, and abnormal fault resolution methods for the air-cooled circuit of a gas-insulated transformer at a Beijing substation, providing technical guidance to enhance the operational safety and stability of forced-air cooled transformers. Through detailed analysis of the air-cooled circuit's operational mechanism combined with practical cases, this paper clarifies the power switching logic and signal transmission architecture of the cooling system. By examining fault prevention and maintenance strategies for critical components including transformer gas pumps and cooling fans, along with standardized inspection protocols and operational guidelines for substation maintenance, the study formulates essential operational precautions for forced-air cooled transformers. Furthermore, it proposes corresponding emergency response procedures and fault mitigation strategies, offering novel theoretical frameworks and practical methodologies to ensure the secure operation of gas-insulated transformer cooling systems, thereby contributing to improved stability and reliability in power systems.
