Smoothing reactor connecting device with gas damping function

Abstract

The invention relates to a gas damping smoothing reactor connecting device, which is arranged between a middle-layer support connecting plate and an inclined strut connecting plate of a smoothing reactor, and comprises a cylinder barrel, a lower cylinder cover, an upper cylinder cover, a bracket foot sleeve, a bracket, a smooth sleeve, a piston rod, a piston plate, an upper connecting plate, a limiting plate and various sealing and stiffening devices. The device can solve the problems that the smoothing reactor is too large in dynamic response under the action of an earthquake, a coupling bus is prone to being pulled and damaged, a connecting device is prone to being damaged, the selection process of a damping device is complex, and universality is poor.

Description

technical field [0001] The invention relates to the technical field of shock absorption of substation equipment, in particular to a gas shock absorption smoothing reactor connecting device. Background technique [0002] As an important part of a large and complex lifeline system, the power system will directly lead to the paralysis of the entire society once it is damaged in a strong earthquake. Power equipment has suffered serious damage in earthquakes over the years. The seismic performance of power equipment is directly related to the safe operation of the power system, and it is necessary to carry out key research. The smoothing reactor refers to an electronic device used in the DC circuit after rectification. In the DC filter circuit, the number of pulses in the circuit is limited, and there is always ripple in the output rectification voltage. This ripple It is often harmful and needs to be suppressed by a smoothing reactor. The converter stations of DC transmission ...

AI Technical Summary

Problems solved by technology

However, there are many problems in the general selection of shock-absorbing connection devices: for example, finite element simulation or test measurement is required in advance when selecting the device, and the workload is large; different smoothing reactors need to be designed according to the requirements of the corresponding shock-absorbing parameters. Poor adaptability; general damping devices require high precision for installation, difficult construction, and complicated construction steps

[0004] The general smoothing reactor does not adopt shock absorption measures when connecting the braces. Under the action of a strong earthquake, the smoothing reactor will produce a large displacement response due to its high height and heavy weight, resulting in a coupling bus. Larger pulling force
