The damage of transformer oil storage and transformer body.
Technical solution used by the utility model is as follows:
A kind of antivibration flexible structure of converter power transformer oil conservator bracket, comprising: 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 aperture one passed through for bolt, the band transverse arc
The surface of the fixed plate of connected in star is provided in the quantity and position and bolt fixed plate of the aperture two, aperture two that pass through for bolt
Aperture one corresponds to one by one；Plain washer is placed in the side in the open arc connected in star face of fixed plate, and threaded one end of bolt is successively
After the aperture one in aperture 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 aperture 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 buffer the destructive power as brought by high vibration.The working principle of above-mentioned antivibration flexible structure is: working as fixed plate
When bearing upper bracket or lower bracket due to vibrating generated stress, after generating perpendicular to the deformation in fixed plate direction, 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 guaranteed
Respectively there are two fixed pivots in upper bracket and lower bracket, connect more reliable.The very few connection of the quantity of fixed cell is less reliable, number
Amount excessively then causes that structure is complicated, cost improves, and cannot effectively improve bonding strength.
Preferably, the aperture two more than arc groove in the fixed plate is circular hole, arc groove aperture below
Two be slotted hole, finely tunes rigging position by slotted hole when slotted hole is arranged in order to install, and is more convenient to complete assembly.
Preferably, the aperture one on the bolt fixed plate is provided with the internal screw thread being adapted with bolt, and bolt is screwed into
It is fastened again by nut after internal screw thread, so that the assembly of antivibration flexible structure is stronger, reliable.
The utility model has the beneficial effects that
1) the utility model structure is simple, easy for installation, and economic input is low in cost；
2) after the upper and lower bracket of oil conservater is using the utility model connection, caused by earthquake and other reasons can be effectively prevent
Damage of the high vibration to transformer oil storage and transformer body.
