Abstract

To improve the design level

process control and to provide safe and reliable operation of 35 kV dry-type air-core reactor

the research on the influence of the coil radial thickness of 35 kV dry-type air-core reactor on the self-inductance geometric coefficient and branch current distribution is of great significance.Therefore

the influence of coil radial thickness of 35 kV dry-type air-core reactor on the self-inductance geometric coefficient and branch current distribution is studied via the finite element method.The results show that by affecting the self-inductance geometry coefficient of the coil

the coil radial thickness affects the distribution of branch current

the total loss and the temperature rise of the reactor.When the turn deviation of the first branch reaches 1.5%

the current in the second branch increases by 139.4%

and the total power loss increases by 21.4%.
