Reactor
A reactor, comprising: a support; a coil wound on an outer surface of the support and including a plurality of coil segments electrically connected in sequence; and at least one first insulating separator disposed on the outer surface of the support and separating the outer surface of the support into a plurality of regions, in which the plurality of coil segments is respectively arranged.
1 . A reactor, comprising:
a support having an outer surface and a hollow inner cavity, wherein a magnetic core is at least partially disposed in the hollow inner cavity of the support;
a coil wound on the outer surface of the support and including a plurality of coil segments electrically connected in sequence;
at least one first insulating separator disposed on the outer surface of the support and separating the outer surface of the support into a plurality of regions in which the plurality of coil segments are respectively arranged; and
one or more positioning bodies disposed on a cavity wall of the hollow inner cavity of the support, wherein the one or more positioning bodies contact against the magnetic core to fix a position of the magnetic core within the hollow inner cavity of the support,
wherein the one or more positioning bodies are configured such that a gap between the magnetic core and the coil is defined and is larger than air gaps in a main magnetic circuit of the magnetic core.
2 . The reactor according to claim 1 , wherein the plurality of coil segments is sequentially arranged in the plurality of regions in a direction from a winding start point of the coil to a winding end point of the coil.
3 . The reactor according to claim 1 , wherein the coil is wound on the outer surface of the support in a single layer.
4 . The reactor according to claim 1 , further comprising:
cooling air ducts arranged between the cavity wall of the hollow inner cavity of the support and the magnetic core.
5 . The reactor according to claim 4 , wherein the magnetic core has two sides, and wherein the cooling air ducts are located on both sides of the magnetic core.
6 . The reactor according to claim 1 , further comprising:
at least one second insulating separator disposed at an end of the support to separate the coil from the magnetic core.
7 . The reactor according to claim 6 , wherein the at least one first insulating separator and the at least one second insulating separator comprise insulating fins.
