Problems solved by technology

The structural characteristics and working principle of the split core reactor itself can not fundamentally eliminate the influence of noise. Domestic manufacturers often use compacted iron core columns and base structures, add rubber vibration isolators between the body and the box, or improve the air gap material. and other methods to reduce the electromagnetic vibration of the reactor, the research on the mechanism of the reactor vibration noise is still relatively small

Abstract

The invention provides an apparatus and a method for reducing vibration of a split-core reactor from a body, Starting from the origin of the electromagnetic vibration of the iron core, namely magnetostriction, the vibration displacement of the iron core is reduced by using the staggered assembly of oriented silicon steel sheets and non-oriented silicon steel sheets, and by using the opposite magnetostriction effect of oriented silicon steel and non-oriented silicon steel in service.

Description

technical field [0001] The invention belongs to the technical field of reactors, and in particular relates to a device and method for reducing the vibration of a split core reactor from a main body. Background technique [0002] Reactor is an important power equipment in the power transmission and transformation system, and plays many different roles in the power system. As a typical structure in the reactor, the split core reactor can not only reduce the residual magnetism, but also effectively control the inductance. It has developed rapidly in recent years and has been widely used. The vibration noise generated by the reactor not only affects its normal operation and service life, but also generates noise interference. How to scientifically and effectively reduce the vibration and noise of power equipment has become an urgent problem to be solved by the power sector and manufacturers. [0003] The core of the split core reactor is assembled from multiple core cakes sepa...
