Description

Technical Field

[0001] The utility model relates to the technical field of transformer equipment improvement, in particular to a reactor body tightening structure and a reactor. Background Art

[0002] With the construction and development of power grids, large-capacity reactor equipment has been used more and more widely. With the increase of product voltage level and capacity, the size of product core and body is getting larger and larger. If the body and the tank wall are tightened by rigid structural parts, the vibration of the product will be transmitted to the tank and external components through the tightening structure, which will bring certain risks to the subsequent operation of the product. Therefore, it is particularly important to optimize the tightening structure and reduce the transmission of the vibration of the reactor body to the tank to control the vibration of the product.

[0003] The Chinese utility model patent with the authorization publication number CN208335943U discloses a body tightening device for transformers and reactors, including an insulating pad, which can be installed in a direction parallel to the oil tank wall and can be fixed on the oil tank wall, and in a direction perpendicular to the oil tank wall, the insulating pad has a preset range of movement; a shock-absorbing pad with a buffering function disposed between the insulating pad and the oil tank wall; and an insulating adjustment pad disposed between the insulating pad and the shock-absorbing pad for adjusting the gap between the insulating pad and the shock-absorbing pad. The tightening device with the above structure can not only ensure that the body is completely tightened, but also effectively buffer the transformer and reactor when they are subjected to external forces during transportation under the buffering effect of the shock-absorbing pad. However, the tightening structure of this structure is an insulating pad and a shock-absorbing pad fixed by a U-shaped fixing plate, and its width is not adjustable. Due to processing errors, if the size is too large, the tightening structure cannot be smoothly installed between the box wall and the device body during the later installation of the tightening structure. The tightening structure needs to be further trimmed and adjusted to match the gap between the box wall and the device body, which makes assembly difficult and inefficient. If the size is too small, the tightening will not be in place, and the tightening and shock-absorbing effects cannot be fully played. Utility Model Content

[0004] Aiming at the problem in the prior art that the reactor body tightening structure cannot adjust the horizontal dimension, resulting in great difficulty in assembly, low efficiency or insufficient tightening, the utility model provides a reactor body tightening structure and a reactor.
