Abstract
The utility model provides a magnetic shielding dry type reactor which comprises an upper star frame (1a), a lower star frame (1b), an inner iron core column (2), a main coil (3), an outer shielding cover (4) and post insulators (5). The outer shielding cover (4) formed by an upper shielding cover (4a) and a lower shielding cover (4b) is arranged on the exterior of the main coil (3). The central ring (11) of the upper star frame (1a) and the central ring of the (11) lower star frame (1b) are respectively provided with a disconnecting groove (12). The magnetic shielding dry type reactor can avoid core saturation, has a good airtight effect and a waterproof effect, does not generate eddy current heat, does not produce magnetic pollution to the surrounding environment and provides a guarantee for the safe running of high-capacity products.
Description
Technical field
The utility model relates to the magnetic screen dry reactor, belong to the power reactor field.
Background technology
Air core reactor is mainly outdoor use, and air core reactor does not have iron circuit, utilizes the air magnetic conduction, and volume is large, and loss is large, during installation, will consider the magnetic distance, and its stray field is large on electronic product impact on every side.
The utility model content
This practicality new purpose is to provide a kind of can the use out of doors, and loss is low, and floor space is little, without local overheating, and the dry reactor of magnetic field shielding magnetic leakage free.
The utility model comprises starframe 1a, lower starframe 1b, inner iron core post 2, main coil 3, external shroud 4, post insulator 5 forms, inner iron core post 2 is placed in central part between starframe 1a and lower starframe 1b, the outer coiling main coil 3 of iron prop 2 at heart, and make inner iron core post 2 and 3 of main coils leave a determining deviation, outside and leave a determining deviation with main coil 3 outsides external shroud 4 is set at main coil 3, external shroud 4 is comprised of upper housing 4a and lower housing 4b, upper housing 4a and lower housing 4b are comprised of by the forms of radiation closed assembly silicon steel sheet, leave certain air-gap separation 41 between the two ends up and down of external shroud 4 and upper starframe 1a and lower starframe 1b, 42, upper housing 4a and the lower housing 4b of external shroud 4 leave certain air-gap separation 43 between the upper and lower, the interior lateral surface of external shroud 4 carries out the insulated enclosure parcel by impregnated glass fibre tow 45 and mica tape 46, have on the centering ring 11 of upper starframe 1a and lower starframe 1b and disconnect groove 12, post insulator 5 is fixedly mounted on the bottom surface of lower starframe 1b.
Upper housing 4a and the lower housing 4b of the utility model external shroud 4 leave certain air-gap separation between the upper and lower, avoid core sataration, and are easy to processing.External shroud adopts glass fibre and mica tape composite construction, airtight waterproof effective.Have disconnection groove 12 and make it can not form closing face on the centering ring 11 of upper starframe 1a and lower starframe 1b, avoid due to the end winding magnetic field concentration, the metalwork cross section produces eddy current, and local overheating, for the safe operation of products with larger capacity is given security.Compare with traditional hollow-core construction, will reduce loss the about 40-50%, floor space reduces the 30-40% left and right, and surrounding environment is not had to electromagnetic pollution.
