Description
【Technical field】
The present invention relates to a kind of vibration absorbers, and in particular to a kind of vibration absorber for high voltage direct current transmission converter valve.
【Background technology】
Some current conversion stations are in the specific position that earthquake takes place frequently, and when an earthquake occurs, the vibrations of the earth cause converter valve
Vibration and over-large displacement, can damage equipment and parts.Therefore, for the normal operation of guarantee converter valve equipment and completely
Property, vibration reducing measure is essential.Since the voltage and current of converter valve equipment is higher ranked, to electrical performance demands more
It is high.The electric property of converter valve will likely be influenced by additionally increasing dampening apparatus in the valve Room, easily influence equipment performance.
【Invention content】
The shortcomings that it is an object of the invention to overcome the above-mentioned prior art, provides a kind of for high voltage direct current transmission
The vibration absorber of valve under the premise of valve Room equipment is not increased, is modified on the basis of former pipe mother, passes through the movement of pipe mother
It stretches to reduce the vibration equipment displacement caused by earthquake, does not influence equipment electric property.
It adopts the following technical scheme that in order to achieve the above objectives：
For the vibration absorber of high voltage direct current transmission converter valve, including the first pipe mother, the second pipe mother, guider and soft company
Fitting；First pipe is female, the second pipe mother is hollow structure, and the second pipe mother is placed in the first pipe mother by guider, is flexible coupling
Part one end is fixed on the first pipe mother inner wall, the other end is fixed on second pipe mother's inner wall, and the first pipe main pipe wall, which is equipped with, limits second
The limiting stand of pipe mother's moving range, the second pipe mother can be axially moveable in the finite region of first pipe mother one end.
Further, heat emission hole is offered on the first pipe main pipe wall.
Further, the flexible link is copper wire.
Further, described big one end in guider one end is small, and one end of the first pipe mother is placed on what guider was relatively large in diameter
One end, one end of the second pipe mother are placed on the smaller one end of guider diameter, and the first pipe mother and the second pipe mother pass through guider
Connection.
Further, the welding of described flexible link one end or be fixed on first pipe mother's inner wall with fastener, other end welding or
It is fixed on second pipe mother's inner wall with fastener.
Further, the first pipe mother and the second pipe mother coaxial arrangement.
The invention has the advantages that：
The vibration absorber of high voltage direct current transmission converter valve of the present invention, without increasing equipment in the valve Room, only need by
Vibration damping mode of the present invention is applied on the pipe mother of the valve Room, and pipe mother and guider are oriented to dress by the way of coaxially connected
It puts and ensure that two pipes are female with one heart, the distance that limiting stand limitation pipe mother can move axially.When earthquake makes equipment generate displacement,
Partial dislocation amount is absorbed by pipe mother that is concentric and can stretching, is had the advantages of simple structure and easy realization.
【Description of the drawings】
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is the sectional view of the present invention；
Wherein：1 for the first pipe it is female, 2 be the second pipe it is female, 3 be guider, 4 be flexible link, 5 be limiting stand, 6 be scattered
Hot hole.
【Specific embodiment】
The present invention is described in further detail in the following with reference to the drawings and specific embodiments, but not as the limit to the present invention
It is fixed.
With reference to figure 1, Fig. 2, the vibration absorber of high voltage direct current transmission converter valve of the present invention includes the first pipe mother 1, the
Two pipe mothers 2, guider 3, flexible link 4, limiting stand 5 and heat emission hole 6；
First pipe mother 1, the second pipe mother 2, guider 3 are hollow structure, and the first pipe mother 1 is equipped with heat emission hole and limiting
Platform 5, one end of the first pipe mother 1 are placed on one end that guider 3 is relatively large in diameter, and one end of the second pipe mother 2 is placed on guider 3 directly
The smaller one end of diameter, the first pipe mother 1 and second pipe mother 2 connected by guider 3, the second pipe mother 2 can in the first pipe mother 1 edge
Axis direction moves, and 4 one end of flexible link welds or is fixed on female 1 inner wall of the first pipe with fastener, and the other end welds or with tightly
Firmware is fixed on female 2 inner walls of the second pipe, there is heat emission hole 6 and limiting stand 5 on the first pipe 1 tube wall of mother, and the second pipe mother 2 can be in the first pipe
It is axially moveable in the finite region of female 1 one end.
Wherein, the first pipe mother 1 and the second pipe mother 2 are coaxially disposed；First pipe mother 1 is equipped with heat emission hole, to improve heat dissipation effect
Fruit increases through-current capability；Limiting stand 5 is for the moving range of the second pipe mother 2 of restriction, 4 copper wire of flexible link.
The vibration absorber of high voltage direct current transmission converter valve of the present invention, only need to be by pipe mother without increasing valve Room equipment
It is transformed upgrading, it is easy to accomplish, it is easily installed, so as to reduce the position that geological process generates converter valve equipment
Move, guider 3 serve connection it is fixed, the second pipe mother 2 can move freely, while connecting tube inside the first pipe mother 1
