Abstract
The utility model provides a transformer ascending flanged base inspection window insulation shielding device which comprises a cover plate fixed on an ascending flanged base through fasteners. A supporting piece is arranged inside the cover plate, a shielding plate is fixed on the supporting piece of the cover plate, a handle is fixed outside the cover plate, and an insulated cardboard is fixed inside the shielding plate through a cloth belt. The shielding plate and the ascending flanged base form an integrated curved surface, and therefore the distortion in a position of an inspection window of the ascending flanged base because of sharp corners is avoided and electric field distribution of the position of the inspection window of the ascending flanged base is improved. In addition, the insulated cardboard which can play the role of insulated protection is fixed on the shielding plate in colligation mode through a cloth belt and electric insulated performance of the position of the inspection window of the ascending flanged base is strengthened. Thus, the transformer ascending flanged base inspection window insulation shielding device can guarantee the safe distance between a lead wire or a casing pipe voltage equalization ball and the ascending flanged base due to the fact that the diameter of the casing pipe ascending flanged base can be reduced properly under the condition that the lead wire or the casing pipe voltage equalization ball of the same high voltage passes.
Description
Technical field
The utility model belongs to high-tension transformer and makes field, particularly a kind of power transformer enclosure inspection hole insulating mask arrangement.
Background technology
Coil head end outlet in the electric power oil-immersed type transformer all needs to cause sleeve pipe by lead-in wire through bushing lifting seat mostly, need to open inspection hole observation voltage equalizing ball position at the bushing lifting seat position or conveniently carry out this position lead processing, consider lead-in wire by field intensity, the creep distance of inspection hole part, with the electrical safety distance around the assurance lead-in wire.Along with the rising of electric pressure, the inner space of bushing lifting seat can not be amplified simply.Thereby need to have a kind of can the Reliable guarantee high voltage under the needed electrical safety spacing of inspection hole part and necessary creepage distance, can make again the as far as possible little inspection hole insulating mask arrangement of diameter of bushing lifting seat.
The utility model content
The purpose of this utility model has been to provide the inspection hole insulating mask arrangement in a kind of high voltage transformer bushings rising seat, has guaranteed the electrical safety distance between lead-in wire and bushing lifting seat on the basis that reduces the bushing lifting seat diameter dimension.
To achieve these goals, the utility model adopts following technical scheme:
A kind of power transformer enclosure inspection hole insulating mask arrangement, comprise with securing member being fixed on cover plate on the seat that raises, the inboard of cover plate is provided with strutting piece, and barricade is fixed on the strutting piece of cover plate, the outside of cover plate is fixed with handle, and the inboard of barricade is fixed with insulating board with strap.
Preferably, the seat that raises is provided with inspection hole, and described barricade is positioned at described inspection hole place.
Preferably, described strap is the straight burr strap.
With respect to prior art, the utlity model has following beneficial effect: compared with prior art, the barricade that adopts in the utility model and rising seat body form complete curved surface, avoided at the electric field distortion of seat inspection hole position owing to the wedge angle generation that raise, improved in the seat inspection hole position Electric Field Distribution that raises; The insulating board of insulation protection has been fixed in colligation on barricade again, the electrical insulation properties of the seat inspection hole position of having strengthened again raising.Thereby in the situation that same high-tension lead-in wire or sleeve pipe voltage equalizing ball pass through, can realize to guarantee suitably reducing the bushing lifting seat diameter going between or sleeve pipe voltage equalizing ball and the electrical safety distance between seat of raising.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is barricade schematic diagram of the present utility model.
Fig. 3 is insulating board schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model device is described further:
See also Fig. 1 to shown in Figure 3, a kind of power transformer enclosure inspection hole of the utility model insulating mask arrangement comprises raise seat 3 and cover plate 1, cover plate 1 usefulness securing member is fixed on the seat 3 that raises, and barricade 5 is fixed on the strutting piece 2 of cover plate 1, and cover plate 1 outside is fixed with handle 4; Insulating board 6 usefulness straps 7 are fixed on barricade 5 inboards.
Install and when using, electric pressure, the field intensity of at first pass through lead-in wire according to institute determine first to select suitable lead-in wire or voltage equalizing ball size; Insulating board 6 is the electric insulation structure, with strap 7 insulating board 6 is fixed on the barricade 5.Barricade 5 is electric shielding structure; Barricade 5 is fixed on strutting piece 2 on the cover plate 1, with securing member cover plate 1, strutting piece 2, handle 4, barricade 5, insulating board 6 and strap 7 is fixed on the seat 3 that raises at last.
The above only is a kind of execution mode of the present utility model, it or not whole or unique execution mode, the conversion of any equivalence that those of ordinary skills take technical solutions of the utility model by reading the utility model specification is claim of the present utility model and contains.
