Description

Description

High-power current-limiting reactors can induce electromagnet fields leading to harmful heating of substation’s metal elements that may affect the equipment performance. To avoid it, the shell-type current-limiting reactor is designed. Their special feature is about the magnet fields induced in the windings which are closed to their side shunts and end yokes, which can significantly reduce scattering fluxes. Also it allows you locating this reactor at a smaller chamber where a standard reactor would not fit well.

The shell-type current-limiting reactor is a winding with a steel magnet core of nonlinear inductive resistance. The magnet core is made of transformer steel sheets stacked by the ‘step-lap’ method. The winding is made of aluminum conductor. The pressing element is a system of steel non-magnetic plates tightened by vertical tie-rods. The contact terminals of the windings are made of aluminum bus bars welded to the reactor conductors, and bolts. The base of the winding is a steel channel that ensure stable and secure fastening of the reactor’s phase to the foundation.
