doi:10.11985/2019.02.011

Abstract

Abstract:

Non-magnetic shielding type, full magnetic shielding type and part magnetic shielding type are simulated to calculate the magnetic field about air-core reactor based on the Ansoft Maxwell software, distribution of magnetic density, magnetic intensities, loss density and inductance are analyzed and compared. The results show that distribution of magnetic lines is decentralized for Non-magnetic shielding type, but whatever distribution of magnetic lines or inductance are very similar for the other two types, the height of magnetic shielding have little effect on inductance, part magnetic shielding type of air-core reactor have good cost advantage because less usage of silicon steel.

Key words: Air-core reactor, magnetic shielding, Ansoft, magnetic intensity, inductance
