摘要 硅钢片的磁致伸缩效应是变压器等电力装备本体振动噪声的主要原因。为了准确地建立取向硅钢磁致伸缩模型,依据硅钢磁畴旋转特性,引入磁畴旋转相关参数k1,对J-A模型进行改进;在此基础上,结合二次畴转模型建立取向硅钢的磁致伸缩模型,并用粒子群优化算法(PSO)提取模型中的多个参数。考虑电力变压器服役环境的影响,该文分别在理想正弦,含谐波、直流偏磁不同条件下开展了取向硅钢磁致伸缩特性分析。结果表明在三种不同状态下,建立的模型计算结果与实验测量的磁致伸缩特性结果具有较好的一致性。该文建立的磁致伸缩模型可应用于取向硅钢在服役条件下磁致伸缩特性模拟。

Abstract:Magnetostrictive effect of silicon steel is the main source of vibration noise for power equipment such as transformers. In order to establish the magnetostrictive model for silicon steel, the magnetic domain rotation characteristics were considered and the related parameter k1 was added in the J-A model. Then, the magnetostrictive model of oriented silicon was established by combing the improved J-A model with the quadratic domain rotation model. The parameters in the model were extracted using the particle swarm optimization algorithm(PSO). Considering the working condition of power transformers, the magnetostrictive properties of oriented silicon steel were analyzed under ideal sine, harmonics and DC bias, respectively. The results showed that the magnetostrictive curves calculated by the model under the different conditions were in good agreement with the experimentally measured data. Therefore, the magnetostrictive model proposed in the paper can be used to simulate the magnetostrictive properties of oriented silicon steel under service conditions.
