Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
As shown in Figure 1-Figure 3, the embodiment of the invention provides a kind of magnetic screen dry-type air-core reactor, comprise: coil body 1, it has certain reactance value and resistance value, be provided with inlet wire aluminium row 12 and outlet aluminium row 13, when practical application, coil body 1 is connected 13 by inlet wire aluminium row 12 and is connected with ambient systems with outlet aluminium, present embodiment does not limit the position that inlet wire aluminium row 12 and outlet aluminium come coil body 1, inlet wire aluminium row 12 position can be higher than outlet aluminium row 13, and inlet wire aluminium row 12 position can also be lower than outlet aluminium row 13; Magnetic shielding cover 2 comprises a plurality of metallic conductor closed hoops 21, and the week that metallic conductor closed hoop 21 is sheathed on coil body 1, metallic conductor closed hoop 21 was not connected with coil body 1 contact laterally, and metallic conductor closed hoop 21 is a plurality of along axially arranging of coil body 1; Support the framework 22 of magnetic shielding cover 2, a plurality of metallic conductor closed hoops 21 positions that consist of magnetic shielding cover 2 are fixed on the framework 22 adjustablely, when practical application, framework can be made of two standpipes that are separately positioned on coil body 1 outside, also can be consisted of by the many calcaneus branches post that is separately positioned on coil body 1 outside (such as three standpipes or four standpipes even the six roots of sensation or eight standpipes), preferred two standpipes are separately positioned on the diameter of coil body 1 or the position at diagonal two ends when being made of two standpipes, a plurality of metallic conductor closed hoops 21 are fixed on two standpipes, and the embodiment of the invention does not limit the particular type of framework.When practical application, coil body 1 is fixed on the contact-making surface by supporting seat 3, and supporting seat comprises insulator (not shown) and transition bearing (not shown).
In order to adjust the shield effectiveness of 2 pairs of leakage fields of magnetic shielding cover, the fixed position of preferred a plurality of metallic conductor closed hoops 21 on framework 22 can be regulated, so that the adjustable interval between a plurality of metallic conductor closed hoop 21.When concrete the application, when needs strengthen the shield effectiveness of 2 pairs of leakage fields of magnetic shielding cover, mobile a plurality of metallic conductor closed hoops 21 in the fixed position on the framework 22 so that the pitch smaller between a plurality of metallic conductor closed hoop 21.When needs weaken the shield effectiveness of 2 pairs of leakage fields of magnetic shielding cover, just move a plurality of metallic conductor closed hoops 21 in the fixed position on the framework 22 so that the spacing between a plurality of metallic conductor closed hoop 21 becomes large.As for how realizing the fixed position of a plurality of metallic conductor closed hoops 21 on framework 22 regulate, present embodiment is not done too much restriction to this, can do various changes on known basis, such as can being to be provided with a plurality of fixing holes at framework 22, when the spacing between the needs adjustment metallic conductor closed hoop 21, realize by the position that changes the fixing hole of metallic conductor closed hoop on framework, can also be at framework 22 gathering sill to be set, when needs are adjusted spacing between the metallic conductor closed hoop 21, realize spacing adjustment between the metallic conductor closed hoop 21 by moving metal conductor closed hoop in gathering sill.
When practical application, can also adjust by the external diameter that changes metallic conductor closed hoop 21 shield effectiveness of 2 pairs of leakage fields of magnetic shielding cover, when needs strengthen shield effectiveness to leakage field, can realize by the external diameter that reduces metallic conductor closed hoop 21.When needs weaken shield effectiveness to leakage field, can realize by the external diameter that increases metallic conductor closed hoop 21.
