Amorphous alloy dry type transformer noise control

      Amorphous alloy iron core is due to the magnetostriction conventional silicon steel sheet is big, the vibration noise than conventional transformer silicon steel sheet.

      The flux density of each rise by 0.02 T, product noise increases about 1 db.

      Same cases, 15 pieces of a set of fan lap than 30 pieces of a set of array lap of amorphous alloy transformer no-load loss and excitation power can be down to 5 ~ 8%, the finished product can average falling by 2 db noise.

      Adopt silicon rubber plate filling in and around the core, in order to have the effect of vibration damping noise reduction.

      After adding damping mounting base, amorphous alloy under dry type transformer noise can take 1 ~ 3 db, has a good noise reduction effect. Xin yu network it share of amorphous alloy dry type transformer noise control

Methods/procedures

1) amorphous alloy iron core in the process of handling transfer shall be handled with great care, avoid core under stress and embrittlement, after packing, open the core core lifting to push loading stage, usable brush in daub some on the side of the core commissure transformer oil, make its penetration into the core plate joint, can play the role of the core plate together, together after the core plate of toughness enhancement, convenient to open operation.

2) USES the magnetic sling to push the amorphous alloy iron core lifting lie on loading platform, open the core plate joint, and the protection board will start after the core protection, in order to avoid to push core into the coil, and can collect a little while core fragments scattered.

3) high and low voltage coil through tooling positioning installation kit first lie in the assembly stage, three-phase coil shall be horizontal, high and low voltage coil position alignment, the article adopt silicon rubber, epoxy plate between the coil support location etc.

4) high and low voltage coil to push up the stage assembly platform, core orientation, can be pushed to core coil, three-phase dry type transformer five pillars of amorphous alloy for four frame structure with five poles, made the four core box into individually, but pay special attention in the process of into the adjacent two box height should be consistent, cuddled up together, and the gap between the core and coil should sift the article silicone rubber and epoxy board hold tight, so it is compact. For large capacity products, core section is larger, often using two layers of core pile, should push pack good, the lower core alignment, hold tight, and encapsulation joint and then push the upper core.

5) into the coil, the core in place after the assembly block and epoxy support plate, and then to core joint encapsulation, core joint encapsulation is will open joint press before the open joint position suits back, and USES the silicone sealant to encapsulate on the side of the commissure, final reoccupy silicon steel sheet will be core encapsulation on the whole. Should pay special attention to joint in the process of encapsulation technique, to avoid damage of amorphous alloy strip breakage, and ensure the joint in place.

 6) core packaged clamp assembly in place, encapsulate the amorphous alloy iron core as a whole, mainly supported by clips and block, epoxy plate stress, so as to complete the body of the whole assembly.
