Embodiment Construction

[0015] The specific implementation manner of the present invention will be described in detail below in combination with the technical scheme and accompanying drawings.

[0016] Take the method of applying a single-layer rotating dynamic magnetic shield in the generator as an example: as shown in Figure 1, a cylindrical rotating magnetic shield made of 1J50 material is used with its upper and lower ground closed The rotor 7 of the casing is installed at the position of the air gap 8 (S pole) and the air gap 9 (N pole) between the main magnetic pole 1, the field winding 2 and the armature winding 3, and the armature core 4, And it can rotate around the rotor axis 6 of the magnetically shielded case.

[0017] At the position of the cylindrical axial surface of the rotor 7 of the rotating magnetic shielding shell, there are two pairs of 4 magnetic flux leakage holes 5 that are mutually called 90°. The symmetrical flux leakage holes 5 in Fig. 1 are positive Facing the position of...

Abstract

Using high magnetic conductity and low coercive force of soft magnetic alloys forms a revolving dynamic magnetic shielding method. A revolving and a non-revolving magnetic shielding body case are designed. Paired isometric flux leakage holes are prepared on the magnetic shielding body case so as to produce purpose made magnetic shielding body case. When flux leakage holes on the revolving magnetic shielding body case are superposed to flux leakage holes on the non-revolving magnetic shielding body case, magnetic lines are passed through flux leakage holes. When flux leakage holes on the revolving case are staggered to flux leakage holes on the non-revolving case, close magnetic shielding body case is formed, and magnetic lines are through the magnetic shielding body cases. The invention can carry out dynamic magnetic shielding, and non-dynamic magnetic shielding for object in magnetic field at any time and any place in order to reach purposes of safe operation and saving energy.

Description

technical field [0001] The invention belongs to the technical field of magnetic shielding, and particularly relates to a method for forming a rotating dynamic magnetic shielding function by using soft magnetic alloy materials. Background technique [0002] At present, in the technical field of magnetic shielding of low-frequency magnetic fields, for objects requiring magnetic shielding, soft magnetic alloy materials are generally used to make a fixed and closed magnetic shielding body. They cannot control the real-time and continuous magnetic shielding and non-magnetic shielding of objects in the magnetic field according to the requirements of actual use. Therefore, it greatly limits the application range and wider practical value of magnetic shielding technology in the magnetic field. Contents of the invention [0003] The purpose of the present invention is to provide a method for manufacturing a rotating continuous and dynamic magnetic shielding method using the charact...
