Description
Technical Field
The invention relates to the technical field of shock absorption of transformer substation equipment, in particular to a gas shock absorption smoothing reactor connecting device.
Background
The electric power system is an important component of a large complex life line system, and once the electric power system is damaged in a strong earthquake, the whole society is directly paralyzed. The power equipment is severely damaged in the past earthquake, the earthquake resistance of the power equipment is directly related to the safe operation of a power system, and important research is needed. A smoothing reactor is an electronic device used in a rectified dc circuit, in which the number of pulses in the circuit is limited, and in which the output rectified voltage always has ripple, which is often detrimental and needs to be suppressed by the smoothing reactor. The converter stations for DC power transmission are all provided with smoothing reactors, so that the output DC is close to ideal DC. The earthquake resistance of the smoothing reactor under the action of earthquake is the key for ensuring the safe and reliable operation of the power transmission system, and due to the strong integrity, if damage occurs in the earthquake, the earthquake can cause great economic loss. In addition, the coupling point between the smoothing reactors is positioned in the upper body, if the reactor body is excessively displaced in an earthquake, the coupling bus is easily damaged by bearing larger traction force, so that the power response of the reactors is reduced.
In order to reduce the dynamic response of electrical equipment, adding shock absorbing devices is a common method in engineering. However, there are a number of problems associated with the general use of shock absorbing attachment devices: if the device is selected, finite element simulation or test measurement is needed in advance, and the workload is high; different smoothing reactors are required to be designed with corresponding damping parameters according to requirements, so that universality is poor; the general damping device has higher installation requirement precision, high construction difficulty and complex construction operation steps.
The general smoothing reactor does not adopt a damping measure when being connected with the diagonal brace, and under the strong shock effect, the smoothing reactor generates larger displacement response due to higher height and larger weight, so that the coupling bus generates larger traction force. Therefore, the design of the gas damping connecting device for the smoothing reactor has great significance, and if the damping connecting device can be simply and conveniently installed in the smoothing reactor, and the damping connecting device does not need to be greatly changed for different smoothing reactors, the application range of the damping connecting device in a transformer substation can be greatly enlarged.
