摘　　要：空载损耗和短路损耗是变压器的重要性能参数,通过测量变压器的空载损耗和短路损耗可及时预测故障的发生,确保其安全稳定运行。在“双碳”目标下,变压器具有很大的节能潜力,及时发现高损耗的变压器并进行全面整治,对于节约能源、缓解电力短缺、保护环境具有重要意义。研究了运行状态下的变压器损耗在线测量方法,以实时高效测量损耗,及时预测变压器的潜在故障,检测其运行效率是否满足国标要求。No-load loss and short-circuit loss are important performance parameters of transformers.By measuring no-load loss and short-circuit loss of transformers,potential faults can be predicted in a timely manner to ensure their safe and stable operation.Nowadays,in the context of"dual carbon"goals,transformers have great energy-saving potential.Timely detection and comprehensive treatment of high-loss transformers are of great significance for energy conservation,alleviating power shortages,and protecting the environment.This paper mainly studies the online measurement method of transformer losses under operating conditions,which can satisfy the demand for real-time and efficient measurement of losses,promptly predict potential faults,and determine whether the transformers have acceptable operating efficiency according to national standards.
