Damage type in electrical equipment earthquake mainly insulator end is broken and leakage of oil.For this situation problem, domestic
Outer a lot of scholar takes different measures to improve its anti-seismic performance.There is scholar to propose by measures such as bracing wire reinforcings and improve side
To rigidity, but the construction of this reinforcing mode is loaded down with trivial details and adds the difficulty that porcelain piece is removed contamination, and easily at pull bar or draw in earthquake
Line fixed position damages；The measures such as metal damper tune are also set, but this method vibration frequency constituent-sensitive over the ground, subtract
Shake effect is unstable；Input earthquake can be isolated by base isolation technology with electrical equipment, but this method can make equipment
Producing bigger displacement, damping device is higher to space requirement.
This utility model is intended to use multiple tuned mass dampers to make electrical equipment have more preferable Bit andits control performance, simultaneously
Reduce the damping device requirement to horizontal space, make the anti-seismic performance of electrical equipment increase.
Utility model content
Given below about brief overview of the present utility model, in order to provide about of the present utility model in terms of some
Basic comprehension.Should be appreciated that this general introduction is not to summarize about exhaustive of the present utility model.It is not intended to determine
Key of the present utility model or pith, be not intended limitation scope of the present utility model.Its purpose is only to simplify
Form provide some concept, in this, as the preamble in greater detail discussed after a while.
In consideration of it, according to an aspect of the present utility model, this utility model is directed to one and hinders based on multiple tuning quality
The hammer damping device of Buddhist nun's device principle, at least to solve the problem of the displacement that electrical equipment generation is bigger in earthquake, and subtracts
Shake device requires higher problem to horizontal space.
A kind of based on multiple tuned mass dampers principle the hammer damping device that the utility model proposes, including multiple tunings
Mass damper unit, multiple tuned mass damper unit circumference array are on electrical equipment top, and each tuning quality hinders
Buddhist nun's device unit all includes a leading screw and at least one mass, and the lower end of leading screw is connected with electrical equipment screw top, leading screw
Upper end threaded with at least one mass, described electrical equipment is current transformer.
Further: the number of described tuned mass damper unit is three to eight.
Further: described leading screw is the screwed metallic rod of same diameter.Leading screw material has certain ductility
Metal material.
Further: described leading screw is copper leading screw.
Further: the mass of multiple tuned mass damper unit, for the cylinder of different size, have in the middle of cylinder
The silk hole being consistent with leading screw size.During work, mass and leading screw pass through screwed connection.But mass is not limited to cylinder,
May also be cube or spheroid.
Further: described mass is irony mass or copper mass.Density of material is big.
The effect that this utility model is reached is:
A kind of hammer damping device based on multiple tuned mass dampers principle of the present utility model, is arranged on electrical equipment
Top, it is intended to reduce the electrical equipment earthquake when earthquake motion effect.This utility model have low cost, damping effect substantially,
Apparatus body is changed little advantage.Compare with conventional electrical devices damping device, there is more preferable Bit andits control performance；With
Similar damping device is compared, and horizontal space of the present utility model requires little.It addition, there is not problem of aging in this utility model,
Capacity of resisting disturbance is strong, and damping device does not exist redundancy quality.
Accompanying drawing explanation
Fig. 1 is the axonometric chart that this utility model is installed on electrical equipment top；
Fig. 2 is the front view that this utility model is installed on electrical equipment top.
Detailed description of the invention
Hereinafter in connection with accompanying drawing, one exemplary embodiment of the present utility model is described.For clarity and conciseness,
All features of actual embodiment are not the most described.It should be understood, however, that it is any this actual real in exploitation
Must make during executing example much specific to the decision of embodiment, in order to realize the objectives of developer, such as,
Meet those restrictive conditions relevant to system and business, and these restrictive conditions may be along with the difference of embodiment
Change.Additionally, it also should be appreciated that, although development is likely to be extremely complex and time-consuming, but to having benefited from this
For those skilled in the art of utility model disclosure, this development is only routine task.
Here, also need to explanation a bit, in order to avoid having obscured this utility model because of unnecessary details, at accompanying drawing
In illustrate only with according to the closely-related apparatus structure of scheme of the present utility model and/or process step, and eliminate with
Other details that this utility model relation is little.
A kind of based on multiple tuned mass dampers principle the hammer damping device of present embodiment, including eight tuning qualities
