变压器运行中温度异常的分析及防范措施

03Analysis of Common Problems in Transformer Operation and Preventive Measures

变压器是电力系统的基础性设备之一,不仅实现变换电压、分配电能和安全隔离等功能,而且也是实现高压输电降低线路损耗的基本手段.其能否正常运行直接关系到电力系统的安全经济稳定,且与工业、农业、科技、医疗、居民生活等息息相关.及时发现变压器运行异常情况,积极采取应对措施是保证变压器正常运行的重要防范措施,同时也直接影响着电力变压器的使用寿命.在运行过程中存在许多不利因素影响其安全经济稳定运行,其中变压器温度异常升高是引发故障的主要原因之一.文章围绕变压器温度异常作全面分析.

Transformer is one of the basic equipment of the power hub system.It not only realizes the functions of voltage conversion,power distribution and safety isolation,but also is the basic means to reduce the line loss of high voltage transmission.Its normal operation is directly related to the security and economic stability of the power system,and is closely related to industry,agriculture,science and technology,medical treatment,and residents’life.Timely finding the abnormal operation of the transformer and actively taking countermeasures are important preventive measures to ensure the normal operation of the transformer,and also directly affect the service life of the power transformer.In the process of operation,many different factors affect its safe,economic and stable operation.Among many hidden factors,the abnormal temperature rise of the transformer is one of the main causes of the failure,This paper will make a comprehensive analysis of transformer temperature anomalies.
