Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of high-power transformer sleeve pipe installation and repairing frock, the cleaning in a pre-installation of big-and-middle-sized oil-immersed power transformer can be solved, drying, test stage hold flimsy problem, sound construction, easy to use, economical and practical.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of high-power transformer sleeve pipe installation and repairing frock,
Article four, oblique supporting leg and the crosspiece of at least one piece of horizontal arrangement that is arranged between four oblique supporting legs are welded into pyramid support, and four oblique supporting legs and ground are 45 ~ 60
0angle is arranged, pyramid cantilever tip is welded with end face platform;
End face Platform center offers flange hole, and flange hole diameter and bushing shell for transformer central flange match, and the end face platform outside flange hole offers multiple bolt connecting hole;
Each oblique supporting leg bottom welding has support baseboard.
Oblique supporting leg is preferably the supporting leg that 50 × 50 or 63 × 63 angle steel are made.
Crosspiece is preferably the crosspiece that 50 × 50 or 63 × 63 angle steel are made.
The quantity of crosspiece is preferably two pieces.
The diameter of flange hole is preferably 550mm.
The diameter of bolt connecting hole is preferably 20mm.
The high-power transformer sleeve pipe installation and repairing frock that the utility model provides, beneficial effect is as follows:
1, pyramid support is welded into by oblique supporting leg and crosspiece, end face Platform center offers flange hole and bolt connecting hole, analogue transformer sleeve pipe actual installation can run operating state, be convenient to bushing shell for transformer and erect unsettled placement, uniform force, non-easy damaged; Guarantee device security, reduce onsite moving damage; When new installation or maintenance bushing shell for transformer, the unsettled vertical stable placement of retaining sleeve, to the conductor of sleeve pipe, porcelain screen and end shield end insulation not damaged, and sound construction, be conducive to the cleaning wiping before sleeve pipe installation, visual examination, dry moistureproof, wiring test, the quality that the installation of raising equipment, maintenance check.
2, be easy to staff's climbing stand, the convenient cleaning wiping dust greasy dirt etc. installing anterior cannula porcelain screen, end shield.
3, hypotenuse inclination angle is large, support structure firm, is conducive to casing safety and places.
4, when bushing shell for transformer is positioned over the utility model, upper and lower side conductor, porcelain screen is unsettled, is convenient to cleaning, wiring; Coordinate ventilation drying equipment, be convenient to ventilation moistureproof, dry; After completing cleaning, drying, test, with clean Polypropylence Sheet wrapping overlapping casing tube upper and lower part, be convenient to deposit, prepare stand-by in advance, save transformer and the straight line duration is installed.
5, multiple stage bushing shell for transformer is installed reusable, improve frock material turnover utilization rate, reduce investment outlay, the cleaning in a pre-installation of big-and-middle-sized oil-immersed power transformer can be solved, drying, test stage hold flimsy problem, sound construction, easy to use, economical and practical.
