Low-noise dry-type iron core reactor assembling process

Abstract

Discloses is a low-noise dry-type iron core reactor assembling process. The assembling process includes the steps: S5-1, taking a flexible pouring guide pipe, blocking one end of the flexible pouring guide pipe, and uniformly drilling small holes in a section equal to the perimeter of an iron core column along a same side of the pouring guide pipe; S5-2, moving the iron core column down to enable a seam on the upper portion to be exposed; S5-3, enabling the pouring guide pipe to surround the seam by one circle, keeping the small holes to face the seam, and using a rubber belt to tension, wind and fix the pouring guide pipe; S5-4, hanging a coil up to enable a seam on the lower portion to be exposed; S5-5, burying the pouring guide pipe at the seam on the lower portion by referring to S5-3, and resetting an upper cushion block and a lower cushion block; S6, transferring a reactor into vacuum pouring equipment, and connecting the guide pipe; S7, vacuumizing to complete vacuum pouring of a seam of the iron core column and an iron yoke; S8, releasing vacuum, and transferring a reactor product into a curing furnace to complete resin curing of the seam. By the low-noise dry-type iron core reactor assembling process, vacuum pouring of the seam of the iron core column and the iron yoke of a dry-type iron core reactor can be realized, firmness in bonding and less proneness to loosening are realized, and seam noise is effectively inhibited.

Description

technical field [0001] The invention relates to an assembly process of a low-noise dry-type iron-core reactor. Background technique [0002] In the traditional dry-type iron core reactor, the iron core column is made of stacked iron core cakes and non-magnetic gaps interlaced and vacuum casted with epoxy resin, but the joint between the iron core column and the iron yoke lacks an effective vacuum casting method. It can only be bonded under normal conditions, and the bonding surface is not firm, and it is easy to loosen under the action of electromagnetic force, resulting in large noise. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an assembly process for a low-noise dry-type iron-core reactor, which can vacuum-cast the joint between the core column and the iron yoke of the dry-type iron-core reactor, and can make the bonding It is firm and not easy to loosen, effectively suppressing joint noise. [0004] To ...

Problems solved by technology

[0002] In the traditional dry-type iron core reactor, the iron core column is formed by stacking iron core cakes and non-magnetic gaps alternately and vacuum casting with epoxy resin, but there is no effective vacuum casting method for the joint between the iron core column and the iron yoke. It can only be bonded under normal conditions, and the bonding surface is not firm, and it is easy to loosen under the action of electromagnetic force, resulting in large noise
