Novel reactor of high -power ring shape

The utility model discloses a novel reactor of high -power ring shape, including magnetic core and coil, the magnetic core makes up the ring shape magnetic core that forms by two the same half circle ring magnetic cores, the diameter of ring shape magnetic core is 7-20 inches, the magnet density of ring shape magnetic core is 5.5gcm3-6.2gcm3, the coil cover is two on the half circle ring magnetic core, the coil stands the coiling by the flat line to become to be spiral helicine enameled wire coil, the half circle ring magnetic core is pour through semicircle loop type mould by the magnetism combined material that ferromagnetic powder and high temperature resin glue are constituteed to make. The utility model discloses simple structure, simple process easily realizes the automation mechanized operation, low in production cost is honest and clean, reactor light in weight, the noise is little, the loss is low, and the surface radiating is good, and is longe -lived, the magnetic core high -usage, the magnetic leakage is few, and EMI is effectual.
