Abstract
The invention discloses a falling object prevention device used for mounting a low-voltage sleeve of a transformer. The structure comprises a cloth liner which is arranged in the transformer and is floated on the surface of transformer oil, wherein the cloth liner is provided with a through hole with the shape and position which correspond to the low-voltage sleeve; a sleeve opening which is connected by a snap fastener is formed in one side edge from the through hole to the cloth liner; a magnet which is adsorbed on the side wall of the transformer is further arranged at one side edge of the cloth liner. With the adoption of the falling object prevention device, a safe region is formed above the transformer oil so that the mounting work of a sleeve is easy and rapid; on one hand, a falling object can be effectively prevented from falling into a transformer body, and on the other hand, the psychological burden of installation workers is reduced and the installation workers can invest more vigor into connection work, so that the smooth proceeding of the installation work of the transformer is effectively guaranteed.
Description
Technical field
The present invention relates to a kind of transformer installation protector, especially a kind of for the anti-falling device of transformer low voltage sleeve pipe is installed.
Background technology
When transforming plant main transformer is installed, because producer considers bridge opening limit for height factor, the 10KV low-tension bushing of transporting to on-the-spot 110kV transformer is not installed together with transformer, at the construction field (site) sleeve pipe and transformer is assembled.Generally, after transformer exhausts the complete oil of vacuum impregnating, low-tension bushing terminals are also connected with low pressure winding, need to be connected with low pressure winding low-tension bushing, but because transformer is now filled with oil, and three reserved cavities that low-tension bushing wiring is installed are very little, and each cavity can only allow an arm to enter, hand of installation personnel will be held bolt and nut, and another hand is held plank and operated.Therefore, because the restriction in space and the blind area in the visual field, installation personnel can only be installed gropingly, the easy like this phenomenon that causes bolt screw rod to fall.
Transformer inside will guarantee definitely insulation, and nut falls in transformer and will have a strong impact on the safety of transformer.For the nut crashing in transformer is taken out, first need the transformer oil in transformer to drain, transformer outer cover is sling, the nut that searching is dropped, due to transformer core is exposed to can not be over 8 hours in air, in eight hours, must find fallen nut, otherwise must again outer cover be lifted and again vacuumize oiling, go round and begin again until find fallen nut.This has affected project progress greatly, expends huge manpower and materials and financial resources.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of for the anti-falling device of transformer low voltage sleeve pipe is installed; it adopts the insulating spacer less than transformer oil density, utilizes suspension theory below low-tension bushing, to form a slice safety zone; played the effect of accepting falling object; improve the fail safe of transformer installation effectiveness and installment work, at protection transformer core insulating square mask, had important effect.
For solving the problems of the technologies described above, the technical solution used in the present invention is as follows:
It is a kind of for the anti-falling device of transformer low voltage sleeve pipe is installed, structure comprises and arranges in transformer, floats over the lip-deep shield of transformer oil, described shield is provided with the through hole corresponding with the shape of low-tension bushing and position, described through hole has to a side of shield the suit mouth connecting by double buckle, and a wherein side of described shield is also provided with the magnet being adsorbed on transformer sidewall.
By suit mouthful by three through holes of shield be stuck in low-tension bushing outer, do not interspace entangle low-tension bushing, then double buckle is fastened, magnet inhales on transformer sidewall, shield is tiled and floats on the surface of transformer oil to form safety zone; Even have falling of bolt or pad in the process that low-tension bushing is installed, can drop down onto on shield, greatly reduce foreign material and crash into the probability in transformer.
The beneficial effect that adopts technique scheme to produce is: the present invention forms safety zone above transformer oil, makes sleeve pipe installment work more easily, fast; Can fall in transformer body by effective anti-falling stop thing on the one hand, installation personnel psychological burden reduces on the other hand, makes it have more energy to drop in connection work, effective guarantee carrying out smoothly of doing of electrical transformer fitter.

Fig. 2 is the structural representation that the present invention uses state;
In figure: 1, shield; 2, magnet; 3, through hole; 4, suit mouthful; 5, floating drum; 6, low-tension bushing.
Embodiment
Following examples describe the present invention in detail.Various raw material used in the present invention and items of equipment are conventional commercially available prod, all can be bought directly and be obtained by market.
Referring to accompanying drawing 1, the structure of a specific embodiment of the present invention comprises and arranges in transformer, floats over the lip-deep shield 1 of transformer oil, key is: described shield 1 is provided with the through hole 3 corresponding with the shape of low-tension bushing 6 and position, described through hole 3 has to a side of shield 1 the suit mouth 4 connecting by double buckle, and a wherein side of described shield 1 is also provided with the magnet 2 being adsorbed on transformer sidewall.Double buckle described in the present embodiment adopts nylon buckles, and nylon buckles is convenient to be set with the sticky of mouth and to tear open.
The side of described shield 1 is also provided with floating drum 5.The one side that arranges of floating drum makes shield float over the surface of transformer oil, makes on the other hand shield tiling, avoids the curling of shield.
During concrete making, first the alternate size of low-tension bushing is measured, recording phase spacing is 20 centimeters, for phase spacing, manufactured the shield of a 80cm * 40cm, according to the position of low-tension bushing 6 and shape, shield 1 is cut to 3 through holes, for sleeve pipe entangling inflexibly do not interspaced, and cut suit mouthfuls 4 in through hole a to side edge of shield, in the both sides of suit mouthfuls 4, make respectively nylon buckles; And then at another side of shield (be provided with on suit mouthful relative side), make the selvedge of fixed magnet 2, magnet is for fixing with the limit of transformer; Finally, arranging floating drum except making three sides of magnet 2, shield is floated on pasta and do not fall.
Referring to accompanying drawing 2, during use of the present invention, first shield 1 is entangled to low-tension bushing 6, then by nylon buckles fastening, finally the shield with magnet 21 is adsorbed on transformer inwall.Shield 1 has just formed 3200 square centimeters of safety zones below low-tension bushing like this, thereby has played the effect of preventing dropped material, has improved operating efficiency, greatly reduces foreign material and crashes into the event in transformer.
Foregoing description only proposes as the enforceable technical scheme of the present invention, not as the Single restriction condition to its technical scheme itself.
