摘　　要：针对眯压器反时限过激磁保护与变压器的实际过激磁能力不相符的问题，由ＭＣＳ－８０９８单片机，采用简单且准确的电压、频率算法和过激磁能力曲一分段线性拟合的方法，实现了新式的变压器过激磁保护。试验结果表明，该保护可以适用于各种过激磁能力的变压器。For the problem of former overexcitation protections mismatching with the actual overexcitation ability of transformers,a new type of overexcitation protection based on MCS-8098 microcomputer for transformer is presented in this paper.The voltage and frequency algorithm is simple and can attain high accuracy.The segmented linearlization method to fit the actual overexcitation curve is adopted.The test result shows that this protection can be proper for all kinds of transformer and can reach higher accuracy.
