Description
Technical field
The utility model relates to converter valve cushion technique fields, and in particular to a kind of suspension type converter valve tower damping device.
Background technique
Suspension type converter valve is the core equipment of DC transmission system, is the bridge that direct current transportation and ac transmission are mutually converted
Beam.Converter valve equipment itself is with high content of technology, involves great expense.
The feature that suspension type converter valve tower structure frequency is low, the period is long, can generate biggish displacement under geological process.It changes
The larger displacement that valve equipment internal element is more, and structure is complicated, and geological process generates is flowed, the integrally-built safety of converter valve is influenced
Property, stability, and converter valve internal element can be damaged, cause the destruction of element.
Utility model content
Technical problem to be solved in the utility model are as follows: a kind of suspension type converter valve tower damping device is provided, is reduced outstanding
The earthquake displacement of hanging change of current valve tower.
In order to solve the above-mentioned technical problem, the utility model adopts the following technical solution:
A kind of suspension type converter valve tower damping device, including hang valve beam, Suspenoing apparatus and dampening assembly, Suspenoing apparatus upper end
It is connect by insulator with valve beam is hung, Suspenoing apparatus includes top layer shielding case and bottom shielding case, top layer shielding case and bottom screen
It covers and is hinged with multiple valve layer blocks between cover, dampening assembly is arranged below Suspenoing apparatus, and dampening assembly includes lifting lug and drag-line, is hung
Ear setting between lifting lug and ground, is provided with damper between two neighboring drag-line again in bottom shielding case lower end, drag-line setting.
Damper includes outer sleeve, and outer sleeve left and right ends are provided with capping, and piston rod is threaded through in outer sleeve, piston
Piston is arranged in the middle part of bar, the right end of right end capping is provided with horseshoe, and horseshoe right end is provided with bearing, sets inside outer sleeve
It is equipped with silicone oil.
Piston diameter is adapted with outer sleeve internal diameter,.
Piston exterior is provided with sealing ring.
Bearing is ball bearing.
Compared with the existing technology, the utility model has the following beneficial effects: the utility model passes through the cooperation of lifting lug and drag-line,
It realizes the constraint to suspension type converter valve tower, reduces the displacement of change of current valve tower under geological process, under geological process, using resistance
The damping of Buddhist nun's device itself provides certain constraint for suspension type converter valve tower in the horizontal direction, reduces change of current valve tower in level side
Upward displacement increases the safety of structure, and cost is relatively low for damper, the maintenance replacement after being conducive to the shake of change of current valve arrangement.
The utility model can reduce the earthquake displacement of suspension type converter valve tower.
