Analysis of 35 kV Dry-type Air-core Reactors Turn-to-turn Field Distribution Based on the Finite Element Method
摘要
Abstract
To study the turn-to-turn electric field distribution in 35 kV dry-type air-core reactor,has a great significance on the mechanism of turn-to-turn discharge fault,and improve its reliability.Therefore,this paper carried out the research of turn-to-turn field distribution in dry-type air-core reactor based on the finite element simulations.The analysis results indicated that the intensity of inter-turn electric field in the outer branch is greater than that in the inner branch.The particularity of the electromagnetic field distribution in 35 kV dry-type air-core reactor leads to the result of end inter-turn electric field intensity in each layer of branch is less than that in the middle section.The inter-turn voltage ratio under 10 kHz and 50 Hz is approximately the same.关键词
