Abstract
The utility model discloses a vibration damping and noise reduction device of a dry type iron-core reactor, which comprises a top cover and a base, and is characterized in that compression springs are uniformly distributed between the top cover and the base. The top cover and the base are made of steel plates; the lower surface of the top cover and the upper surface of the base are welded with an upper steel pipe and a lower steel pipe correspondingly; and two ends of the compression springs are arranged in the upper steel pipe and the lower steel pipe. The number of the compression springs is determined according to the weight of the iron-core reactor, and generally, 4 to 10 compression springs are arranged. A bolt is also arranged for convenient transportation; and the bolt penetrates the top cover, the compression springs and the base, and then is fixed. The vibration damping and noise reduction device is additionally provided with the compression springs reasonably and accurately, thus leading to small overall dimension and stable and reliable structure; and the vibration damping and noise reduction device adopts common material, has convenient processing, and has lower cost and remarkable vibration damping effect and noise reduction effect compared with the vibration damping and noise reduction measures of other dry type iron-core reactors.

Technical field
The utility model relates to the vibration and noise reducing device of the dry-type iron-core reactor in a kind of power equipment, particularly dry-type iron-core reactor.
Background technology
At present, along with 110 kv substations are directly gone into load center, along with a large amount of uses of cable, capacity is greater than 3000 kilovars, and electric pressure is that 10 kilovolts, 35 kilovolts dry-type iron-core reactor consumption heightens.Simultaneously, more and more higher to the vibration and the noise requirements of product, more and more stricter to the environmental impact requirement of product.The vibration and noise reducing of dry-type iron-core reactor is a focus in the industry always, generally is to reduce vibration and noise by falling modes such as low magnetic density on body, still, therefore makes product material consumption obviously increase, and cost up is necessary further improvement and perfect.
The utility model content
The purpose of this utility model aim to provide a kind of simple and reasonable, assembling is quick, with low cost, reduce the vibration and noise reducing device of vibration and the significant dry-type iron-core reactor of noise effects, to overcome weak point of the prior art.
Press the vibration and noise reducing device of a kind of dry-type iron-core reactor of this purpose design, comprise top cover and base, its architectural feature is to be evenly equipped with the compression spring between top cover and the base.
Described top cover and base are made with steel plate, and top cover lower surface and base upper surface correspondence are welded with up and down steel pipe, and the two ends of compression spring are inserted up and down among the steel pipe.
Long 300～500 millimeters, wide 250～450 millimeters, thick 10～15 millimeters of described top cover steel plate; 80～120 millimeters of outer diameter of steel pipes, high 40～70 millimeters, 5～10 millimeters of wall thickness.
Described compression spring is by 10～16 millimeters spring steel wire coilings of diameter, and the number of turns is 4～10 circles, and decrement depends on the matter material of spring and the weight of dry-type iron-core reactor, is generally the 40-60 millimeter.The quantity of described compression spring is decided according to the weight of dry-type iron-core reactor, is generally 4～10.
The utility model is by rationally correctly installing the compression spring additional, and overall dimension is little, and structure is solid and reliable, adopts conventional material, and is easy to process, compares other dry-type iron-core reactor vibration and noise reducing measure, with low cost, alleviates vibration and reduce noise effects remarkable.
