Abstract
A gapless core reactor includes a saturable magnetic core having reactor legs without air gaps and multiple windings. The windings are each wound around a common leg, spaced apart from each other and connected in counter series. The windings are configured such that a magnetic flux generated from an alternating current flowing through the windings generates a plurality of substantially equal and counter magnetic fluxes flowing through two or more separate magnetic circuits.
Claims21
A gapless alternating current core reactor comprising:
- a magnetic core, the core comprising a plurality of substantially uniform reactor legs without air gaps;
- and
- a single coil forming a plurality of windings, each wound around a common leg, wherein the plurality of windings having a first windings wound around the common leg in a first direction, and followed by a second windings wound around the common leg in a second direction opposite to the first direction, such that the first windings and the second windings of the single coil are continuous, in series, spaced apart from each other and in counter series connection;
- where the first and the second windings are configured in such a way that a magnetic flux generated from an alternating current flowing through the first and the second continuous windings generate a substantially equal magnetic flux and a counter magnetic flux flowing through two or more separate magnetic circuits that repel each other absent a ground where energized by an alternating current source;
- where the first and the second windings each include parallel linear end segment positioned between the first and the second windings and separated by an equidistant core separation that is substantially equal to a width of a cross-sectional area of the substantially uniform reactor legs.

A three-phase gapless alternating current core reactor comprising:
- a saturable magnetic core, the core comprising a plurality of reactor gapless legs;
- and
- a plurality of winding pairs, each winding pair formed from a single coil wound around a gapless leg of the plurality of reactor gapless legs, and within each winding pair comprising a first windings wound around a respective gapless leg in a first direction, and followed by a second windings wound around the respective gapless leg in a second direction opposite to the first direction, such that the first windings and the second winding are continuous, in series, spaced apart from each other and in a counter series connection;
- where the first winding and the second windings are configured in such a way that a magnetic flux generated from an alternating current flowing through the first winding and the second windings generate two or more substantially equal and counter magnetic fluxes that repel each other and flow through separate and mutually exclusive magnetic circuits in the respective gapless leg;
- and
- where the first winding and the second winding each include parallel linear end segment positioned between the first and the second windings and separated by an equidistant core separation that is substantially equal to a width of a cross-sectional area of the reactor legs.
