Description
Technical field
The present invention relates to power construction method and technology fields, and in particular to large size ± 500kV converter power transformer is installing
Attachment rotates 180 ° of methods in place after having infused oil.
Background technique
In recent years, the features such as DC transmission engineering is big, line loss is low with its transmission capacity, applies to more and more widely
In power grid.Converter power transformer is the core equipment of converter station to guarantee the safe and reliable stable operation of converter station, is changed in design
When stream station, spare 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 involves, then the traction of spare converter power transformer is put into operation in place.Spare converter power transformer is all to install all attachmentes,
And add oil and be drawn to operating position again later, the converter power transformer or spare converter power transformer either to break down,
All it is weight weight, center of gravity height, cost height, replaces time-consuming and laborious.During replacing converter power transformer, if converter power transformer side
To not right, it is necessary to first adjust converter power transformer direction.It is all to be discharged at well word insurance brace to stamp after converter power transformer transports to scene
Or on dedicated trailer wagon, converter power transformer is transported to again by destination locations by traction.At this point, 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 converter power transformer is jacked 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 groined type two heavy rail C being parallel to each other of oblique placement stamped between B along wood, 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, pushes hydraulic mandril, two hydraulic mandril phases with the high pressure oil that high-pressure oil pump provides
Mutually cooperation, horizontal pushing tow converter power transformer it is diagonal, rotate converter power transformer slowly on heavy rail；Converter power transformer turns
After dynamic certain angle, then converter power transformer jacking got up, is adjusted converter power transformer after the angle of bevel of heavy rail again
It is placed on heavy rail, then pushes two diagonally positioned hydraulic mandrils, converter power transformer is made to continue to delay on heavy rail
Slow rotation.By the converter power transformer that repeatedly rises and falls, heavy rail position angle is adjusted, is repeatedly pushed with hydraulic mandril, is finally made
Converter power transformer turns to required direction.This method has the following problems: 1, since construction site locally backfills region soil property
It is soft, and rail and the contact area set up between the sleeper that wood is stamped are smaller, pressure is big, can be to pillow in uneven subsidence
While wood damages, rail recess also will cause, in fact it could happen that the security risks such as converter power transformer sideslip.2, it rail and changes
It can be produced relative sliding between the bottom plate of convertor transformer, damage the antifouling paint of converter power transformer bottom plate, lead to converter power transformer
Bottom plate gets rusty in the future.3, the accessories such as hydraulic mandril D appropriate must be selected by calculating, if improper, when pushing tow, it may appear that set
Standby to push up motionless, turning one's coat is that rail is dragged and released by hydraulic mandril of the clamp on rail.Major safety risks are caused to equipment.
4, the pushing tow position of hydraulic mandril of the clamp on rail, with the rotation of converter power transformer, pushing tow position is also changing, 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
In addition).5, the limited angle that converter power transformer rotates every time on rail needs repeatedly converter power transformer jacking to get up to adjust
Whole groined type brace stamps the locality with heavy rail, not only large labor intensity, but also construction efficiency is low.
Summary of the invention
