铁心接缝对变压器振动噪声的影响研究
Study on the Influence of Core Joints on Vibration and Noise of Transformer
摘要
Abstract
Noise reduction in transformer proper is a key issue that both power grid companies and manufacturers focus on addressing.The main source of transformer noise is from the core vibration,while the vibration and noise at the core joints shall also not be ignored.In this paper,through modeling the single silicon steel at the transformer joint area,the different lapping forms,lapping width and the number of laminations at each stage are simulated and calculated,the influence of Lorentz force on the core vibration due to the magnetic flux passing through the joint area is analyzed,and the method of vibration reduction and noise reduction based on the joint form is proposed from the microscopic perspective.The influence of Lorentz force on vibration noise is further verified through clamping force test,which provides effective theoretical support for noise reduction of transformer.关键词
