Embodiment 1

[0055] The device for reducing the vibration of the substation reactor provided by the present invention is as follows: Figure 1-Figure 4 shown, where figure 1 is a front view of an exemplary apparatus for reducing vibration of substation reactors, figure 2 is a side view of an exemplary apparatus for reducing vibration of substation reactors, image 3 It is the basic plan view of the reactor of the device of the present invention, Figure 4 for the edge image 3 Sectional view at position 1-1 along the middle.

[0056] The apparatus for reducing the vibration of a substation reactor of the present invention includes: a reactor 100 ; a reactor foundation 200 ; and an anti-vibration joint 300 . details as follows.

[0057] The reactor 100 of the present invention is also called an inductor, examples of which include but are not limited to: dry-type air-core reactors, dry-type iron-core reactors, oil-immersed iron-core reactors, oil-immersed air-core reactors, and clamp-t...

Embodiment 2

[0070] This embodiment provides a method for reducing vibration of a substation reactor, which includes:

[0071] (1) Provide the reactor 100;

[0072] (2) providing a reactor base 200, the reactor 100 and the reactor base 200 are fixedly connected by at least one connector provided at least on the reactor base 200;

[0073] (3) An anti-vibration joint 300 is formed between the reactor foundation 200 and the floor plate 400 on at least one side adjacent thereto.

[0074] The specific structure can be seen in the description of Embodiment 1, which will not be repeated here. The anti-vibration joint 300 between the floor plate 400 and the reactor foundation 200 is filled with grease, foam and rubber strips, specifically: the bottom is caulked with grease, The center is filled with foam, and the surface is caulked with rubber strips.

Abstract

The invention discloses a method and device for reducing vibration of a transformer substation reactor. The device comprises a reactor. A reactor base; the electric reactor is fixedly connected with the electric reactor foundation through at least one connecting piece, the fixing piece is at least arranged on the electric reactor foundation, and the anti-vibration seam is arranged between the electric reactor foundation and a floor slab on at least one side adjacent to the electric reactor foundation. According to the method and device for reducing the vibration of the transformer substation reactor, the vibration load transmission path can be shortened, and the vibration influence range is reduced. Besides, a traditional mode of making a reactor foundation on a floor is changed, the reactor foundation is separated from the floor, and an anti-vibration gap is reserved between the floor and the reactor foundation, so that the vibration load of the reactor is prevented from being transmitted to the floor through the foundation, the floor is prevented from generating resonance, the vibration influence range of the reactor is greatly reduced, and the service life of the reactor is prolonged. Therefore, the adverse effect of the vibration of the reactor on the building structure is solved.

Description

technical field [0001] The present invention relates to the technical field of power equipment, in particular to a method and device for reducing vibration of a substation reactor. Background technique [0002] With the development of power distribution systems, reactors have been widely used. But at the same time, the vibration (sometimes also called "vibration") generated by the reactor brings certain hidden dangers and troubles. The vibration of the reactor is the result of many complicated factors. The reasons for the vibration may be in the following points: a. The failure of the magnetic circuit mainly refers to the magnetic saturation; b. Due to the segmentation of the iron core column, the iron core or pressure Loose parts and mechanical resonance; c. The working current of the inverter is abnormal. At present, a series of shock absorption studies have been carried out on the reactor structure. [0003] For example, Chinese patent application CN104485206A disclose...
