Description
Technical field
The present invention relates to power construction method and technology field, and in particular to large-scale ± 500kV converter power transformers are being installed
Annex, 180 ° of methods in place of rotation are noted after oil.
Background technology
In recent years, DC transmission engineering applies to more and more widely so that its transmission capacity is big, the low feature of line loss
In power network.Converter power transformer be the nucleus equipment of current conversion station in order to ensure the safe and reliable stable operation of current conversion station, changed in design
During stream station, standby converter power transformer will be considered, once certain converter power transformer breaks down, it is necessary to first by failure change of current transformation
Device is involved, then the traction of standby converter power transformer is put into operation in place.Standby converter power transformer is all to install all annexes,
And add and be drawn to operating position again after oil, the converter power transformer or standby converter power transformer either broken down,
All it is weight weight, center of gravity height, cost height, replacing is wasted time and energy.During converter power transformer is changed, if converter power transformer side
To not right, it is necessary to first adjust converter power transformer direction.Converter power transformer is transported to behind scene, is all to be discharged at well word insurance brace to stamp
Or on special trailer wagon, converter power transformer is transported to by destination locations by traction again.Now, if the direction of converter power transformer
It is not right, it is also necessary to first to adjust its direction.
In the prior art, converter power transformer adjustment direction is all that converter power transformer is first discharged to the groined type support put up
Wood is stamped, then by converter power transformer jacking certain altitude, as shown in figure 1, in the bottom plate of converter power transformer A (shown in two-dot chain line)
And wood stamps the heavy rail C that the oblique placement two of the groined type stamped between B along wood is parallel to each other, and converter power transformer is slowly fallen
It is placed on two heavy rails, then, two hydraulic mandril D is arranged diagonal difference clamp on two heavy rails, liquid
Bar front end of bearing down on one is withstood on converter power transformer, and the hydraulic oil provided with high-pressure oil pump promotes hydraulic mandril, two hydraulic mandril phases
Mutually coordinate, horizontal pushing tow converter power transformer it is diagonal, converter power transformer is slowly rotated on heavy rail；Converter power transformer turns
Move after certain angle, then converter power transformer jacking is got up, after the angle of bevel of adjustment heavy rail by converter power transformer again
It is placed on heavy rail, then promotes two diagonally positioned hydraulic mandrils, converter power transformer is continued on heavy rail slow
Slow rotation.By the converter power transformer that repeatedly rises and falls, heavy rail position angle is adjusted, is repeatedly promoted, finally made with hydraulic mandril
Converter power transformer turns to required direction.There is problems with this method：1st, because job site locally backfills region soil property
It is soft, and rail and the contact area set up between the sleeper stamped of wood are smaller, pressure is big, in the case of uneven subsidence, can be to pillow
While wood causes damage, can also rail be caused to be recessed, in fact it could happen that the security risk such as converter power transformer sideslip.2nd, rail and change
Relative slip can be produced between the bottom plate of convertor transformer, the antifouling paint of converter power transformer bottom plate is damaged, causes converter power transformer
Bottom plate gets rusty in the future.3rd, must be by calculating the accessories such as the appropriate hydraulic mandril D of selection, if improper, during pushing tow, it may appear that set
Standby to push up motionless, it is that rail is dragged and released by hydraulic mandril of the clamp on rail to turn one's coat.Major safety risks are caused to equipment.
4th, the pushing tow position of hydraulic mandril of the clamp on rail, with the rotation of converter power transformer, pushing tow position is also in change, non-
The pushing tow position pushing tow of design, it is possible to make converter power transformer tank wall deform, certainly will be left hidden danger to equipment safety operation (after
Add).5th, the limited angle that converter power transformer rotates every time on rail by converter power transformer jacking, it is necessary to repeatedly get up to adjust
Whole groined type brace stamps the locality with heavy rail, and not only labor intensity is big, and efficiency of construction is low.
The content of the invention
The problem of existing present invention aim to address above-mentioned prior art can be efficiently by converter power transformer there is provided one kind
Direction rotates 180 °, and safe and reliable method.
The purpose of the present invention is achieved through the following technical solutions：
