Description
Technical field
The invention belongs to transformer production mounting technique field more particularly to a kind of in-site installation place antivibration are more demanding
Converter power transformer oil conservator bracket antivibration flexible structure.
Background technology
With the development of global energy internet, extra-high voltage direct-current transmission technology moves forward steadily, and a large amount of extra-high voltage direct-currents are defeated
Electrical engineering worldwide develops, and converter power transformer is expensive as one of most important equipment in DC transmission system,
Its reliability influenced for system entirety it is huge, once be seriously damaged in strong earthquake or other vibrations, no
Direct economic loss can be only caused, large-area power-cuts can be led to when serious so that influencing normal production, the life in paralysis region
Apply flexibly electricity.
In converter transformer structure, oil conservater generally apart from transformer body top farther out, especially to vibration require pole
For harsh offshore wind farm converter power transformer, the Vibrant buffer ability of conventional structure is limited, and oil conservater is easy to meet with because of vibration
To damage.Meanwhile the damage of oil conservater can cause the damages such as deformation, tearing by oil conservator bracket to transformer box wall, in turn
Cause the major disasters such as fire and explosion.
Invention content
In order to solve the above technical problems, the present invention proposes a kind of antivibration flexibility knot of converter power transformer oil conservator bracket
Structure cooperatively forms flexible support with bolt by fixed plate and connects, and high vibration caused by earthquake and other reasons can be prevented to becoming
The damage of depressor oil conservater and transformer body.
The technical solution adopted in the present invention is as follows：
A kind of antivibration flexible structure of converter power transformer oil conservator bracket, including：At least a pair of of fixed cell and interposition
Set the fixed plate with lateral arc groove, the fixed cell by one piece of bolt fixed plate, two bolts, two plain washers and
Two nut compositions, the surface of the bolt fixed plate is symmetrically provided with the trepanning one passed through for bolt, the band transverse arc
The surface of the fixed plate of connected in star be provided with the trepanning two, trepanning two that pass through for bolt quantity and position on bolt fixed plate
Trepanning one corresponds to one by one；Plain washer is positioned over the side in the open arc connected in star face of fixed plate, and threaded one end of bolt is successively
After the trepanning one in trepanning two, bolt fixed plate in plain washer, fixed plate, fastened by nut.Specifically used process
In, the number of openings in the side corresponding position trepanning of converter power transformer oil conservater upper and lower bracket, upper and lower bracket is identical, will be upper
It states antivibration flexible structure to be fixedly mounted at the connection cooperation of upper and lower bracket, fixed plate open arc connected in star one is facing towards outer when installation
Side can effectively be buffered due to destructive power caused by high vibration.The operation principle of above-mentioned antivibration flexible structure is：Work as fixed plate
Upper bracket or lower bracket are born due to when stress, being generated after the deformation in fixed plate direction caused by vibration, by solid
The telescopicing performance of arc groove arc surface on fixed board restores deformation in time.
Preferably, a kind of antivibration flexible structure of converter power transformer oil conservator bracket includes two solid to (i.e. four groups)
Order member.Two pairs of fixed cells are distributed in respectively at oil conservater upper and lower bracket, respectively there is two groups of fixed cells on upper and lower bracket, are ensured
Respectively there are two fixed pivots in upper bracket and lower bracket, connection is more reliable.The very few connection of quantity of fixed cell is less reliable, number
It measured and complicated, cost is at most caused to improve, and bonding strength cannot be effectively improved.
Preferably, the trepanning two more than arc groove in the fixed plate is circular hole, arc groove trepanning below
Two be slotted hole, and rigging position is finely tuned by slotted hole when setting slotted hole is in order to install, and is more convenient to complete assembly.
Preferably, the trepanning one on the bolt fixed plate is provided with the internal thread being adapted with bolt, and bolt is screwed into
It is fastened again by nut after internal thread so that the assembly of antivibration flexible structure is more securely, reliably.
Beneficial effects of the present invention：
1) the configuration of the present invention is simple, easy for installation, economic input is of low cost；
2) it after the upper and lower bracket of oil conservater is using present invention connection, can effectively prevent caused by earthquake and other reasons acutely
Vibrate the damage to transformer oil storage and transformer body.

Specific implementation mode
Below in conjunction with the accompanying drawings, embodiments of the present invention are illustrated.
As shown in Figure 1, being the dimensional structure diagram of the present invention, a kind of antivibration of converter power transformer oil conservator bracket is flexible
Structure, including：The fixed plate 2 of four groups of fixed cells 1 and centre position band transverse direction arc groove.
As shown in Fig. 2, being the partial enlarged view of the fixed cell of the present invention；As shown in figure 3, being the fixed plate of the present invention
Front view；As shown in figure 4, being the left view of the fixed plate of the present invention.The fixed cell 1 is by one piece of bolt fixed plate 3, two
4, two plain washers 5 of a bolt and two nuts 9 form, and the surface of the bolt fixed plate 3 is symmetrically provided with to be passed through for bolt 4
Trepanning one, trepanning one be provided with internal thread.The surface with fixed plate 2 is provided with trepanning two, the trepanning passed through for bolt 4
Two quantity and position and the trepanning one on bolt fixed plate 3 are corresponding one by one；Wherein, four more than arc groove trepannings two are
Four trepannings two below of circular hole, arc groove are slotted hole.The one of 2 open arc connected in star of fixed plate is facing towards outside when installation,
The lateral surface for the fixed plate 2 that plain washer 5 is positioned over, it is recessed that threaded one end of bolt 4 sequentially passes through plain washer 5, band arc
Trepanning two in the fixed plate 2 of slot after the trepanning one being screwed on bolt fixed plate 3, is fastened by nut 9.
As shown in figure 5, being the installation effect diagram of the present invention.The side of the upper and lower bracket of converter power transformer oil conservater point
The hole for not opening identical quantity passes through for bolt 4.It, will be with transverse direction after the upper and lower bracket installation of converter power transformer oil conservater is in place
The fixed plate 2 of arc groove is positioned over the lateral surface at the upper and lower bracket cooperation of converter power transformer oil conservater, by four groups of fixation lists
Member 1 is placed in the medial surface at upper and lower bracket cooperation, and upper and lower bracket contact surface Vertical Square is completed by the bolt 4 in fixed cell 1
The assembly of antivibration flexible structure is completed in upward fixation (the Y-direction side, the direction i.e. in figure are identical with the direction of bolt 4).
When transformer body (flexible support lower part) or oil conservater (flexible support top) are vibration source point, which can be big
The vibration of big buffering Y-direction.Operation principle is as follows：1, the fixed plate 2 of open arc connected in star has the function of buffering stress deformation；2、
Four groups of fixed cells can successively be put into the bearing of stress, stress is bigger, undertakes the unit number of stress according to the size of stress
Amount is more, and the components of stress of different gradients are born in cooperation.This structure has effectively buffered certain high vibration and has been stored up to transformer
The destruction of Oil Tank and transformer body, it is simple in structure, it is with obvious effects, there is stronger feasibility.
