Abstract

The invention relates to a converter transformer valve side ascending flanged base shock absorption and energy absorption supporting device, and belongs to the technical field of power transmission and transformation equipment manufacturing and maintenance. The technical scheme is as follows: a support arm (2) is fixed on a converter transformer body (1); a damping cross beam (3) is fixed on the support arm (2); ends of the two pieces of supporting square steel (6) are fixed to the two ends of the damping cross beam (3) respectively, the other ends of the two pieces of supporting square steel(6) are fixed to a valve side ascending flanged base (10), the fixing positions of the two pieces of supporting square steel on the valve side ascending flanged base are close to a valve side sleeve (11), and a triangular structure is formed between the two pieces of supporting square steel (6) and the damping cross beam (3). An energy absorption beam (7) is arranged between the two pieces of supporting square steel. The device can effectively solve the overall strength problem of the valve side system in the in-plant transfer, test or on-site in-place process of the converter transformer, therigidity of the valve side ascending flanged base is matched with the rigidity of the valve side sleeve, and the root breakage of the valve side sleeve under the earthquake working condition is prevented.

Description

technical field [0001] The invention relates to a shock-absorbing and energy-absorbing supporting device for a raised seat on a valve side of a converter transformer, belonging to the technical field of manufacturing and maintaining power transmission and transformation equipment. Background technique [0002] With the development of science and technology, the capacity of power transmission projects in my country continues to increase, and the capacity of converter transformers also increases accordingly. The current of the bushing on the valve side increases, resulting in an increase in the diameter of the valve side lifting seat, and a proportional increase in the overall weight of the valve side outlet system. The supporting strength of the rising seat on the valve side of the converter transformer is insufficient, which may even cause fracture accidents of the valve side bushing and the fixing bolts of the rising seat. [0003] At present, the conventional strengthening ...
