Anti-vibration flexible structure for converter transformer oil storage cabinet support

Abstract

The invention relates to an anti-vibration flexible structure for a converter transformer oil storage cabinet support. The anti-vibration flexible structure comprises at least one pair of fixing unitsand a fixing plate. A transverse arc-shaped groove is formed in the middle of the fixing plate, each fixing unit comprises a bolt fixing plate, two bolts, two flat washers and two nuts, first open holes are symmetrically formed in the surfaces of the bolt fixing plates, the bolts can penetrate the first open holes, second open holes are formed in the surface of the fixing plate, the bolts can penetrate the second open holes, and the quantity and the locations of the second open holes are in one-to-one correspondence to the quantity and the locations of the first open holes in the bolt fixingplates; the flat washers are arranged on the side, in which the arc-shaped groove is formed, of the fixing plate, and a threaded end of each bolt sequentially penetrates the corresponding flat washer,the corresponding second open hole in the fixing plate and the corresponding first open hole in the corresponding bolt fixing plate and then is fastened by the corresponding nut. The anti-vibration flexible structure has the advantages that the anti-vibration flexible structure is simple and economical and is convenient to mount and low in input cost; transformer oil storage cabinets and transformer bodies can be effectively prevented from being damaged by earthquake and violent vibration due to other reasons.

Description

technical field [0001] The invention belongs to the technical field of transformer production and installation, and in particular relates to an anti-vibration flexible structure of a converter transformer oil conservator support with high anti-vibration requirements at the site installation site. Background technique [0002] With the development of the Global Energy Internet, the UHV DC transmission technology is steadily advancing, and a large number of UHV DC transmission projects have been developed around the world. As one of the most important equipment in the DC transmission system, the converter transformer is expensive, and its reliability is important for The system as a whole has a huge impact. Once it is severely damaged by a strong earthquake or other vibrations, it will not only cause direct economic losses, but also cause large-scale power outages that affect normal production and domestic electricity consumption in the paralyzed area.

[0002] With the development of the Global Energy Internet, the UHV DC transmission technology is steadily advancing, and a large number of UHV DC transmission projects have been developed around the world. As one of the most important equipment in the DC transmission system, the converter transformer is expensive, and its reliability is important for The system as a whole has a huge impact. Once it is severely damaged by a strong earthquake or other vibrations, it will not only cause direct economic losses, but also cause large-scale power outages that affect normal production and domestic electricity consumption in paralyzed areas.

[0003] In the converter transformer structure, the oil conservator is generally far away from the upper part of the transformer body, especially for offshore wind power converter transformers that have extremely strict vibration requirements. The vibration buffering capacity of the conventional structure is limited, and the oil conservator is easily damaged due to vibration.

At the same time, the damage of the oil conservator will cause deformation, tearing and other damage to the transformer box wall through the oil conservator support, which will cause major disasters such as fire and explosion
