为准确掌握变压器的真实运行工况，对变压器的状态评估方法进行对比研究，找出不同评估方法的优缺点和共同规律。首先对变压器风险评估和信任度评估的基本原理进行分析，找到各自算法本身的优缺点。在此基础上对云南电网的50台变压器分别进行状态评估，得到其信任度和安全指数。最后进行对比研究，确定了状态检修策略中与评估结果相对应的阀值。该研究为变压器的状态检修提供更全面有效的评估依据，对电网的经济安全运行有着重要的指导意义。

To get accurate knowledge of the real operating conditions of the transformer, different assessment methods are compared to identify the strengths, the weaknesses and the common law. First of all, the basic principles of the risk assessment and the transformer trust assessment are analyzed to find the advantages and disadvantages of each algorithm, and then the condition assessment of Yunnan Power Grid 50 transformers is conducted on this basis and the trust degree and security index are calculated. Finally, a comparative study is conducted and the threshold for condition-based maintenance strategy corresponding to the results of the assessment is identified. It will provide a more comprehensive and effective assessment basis for the transformer condition-based maintenance, and has an important guiding significance for economic and safe operation of the power grid.
