Abstract

The utility model relates to a leading-out structure of a transformer bushing end screen. The leading-out structure of the transformer bushing end screen comprises leading-out pipelines, wherein each leading-out pipeline is led out from an end screen leading-out joint, and is downward led to a space between a transformer body and a heating radiator from the end screen leading-out joint; at the flange of the ascending flanged base of the transformer, each leading-out pipeline is fixed to the flange of the ascending flanged base of the transformer by virtue of a first pipeline fixing support; below the ascending flanged base of the transformer, each leading-out pipeline is fixed to an oil tube flange of the heating radiator of the transformer by virtue of a second pipeline fixing support; each leading-out pipeline is led horizontally from the oil tube flange of the heating radiator of the transformer to a cat ladder of the transformer; each leading-out pipeline is subjected to quarter turn in a vertical downward direction by virtue of a third pipeline fixing support, and is connected with the earth plate of the end screen at the rear side of the cat ladder of the transformer. The leading-out structure of the transformer bushing end screen provided by the utility model has the characteristics that laying of the leading-out pipelines is fast, reliable, reasonable and orderly, and no menace is caused to operations of other auxiliary devices.

Description

The Transformer Bushing Tap deriving structure

Technical field

The utility model relates to the transformer technology field, especially relates to the Transformer Bushing Tap deriving structure.

Background technology

Transformer is one of most important equipment of electric power system, and under Transformer Bushing Tap, drawing is the necessary technology means that realize the transformer belt electro-detection.The transformer device structure complexity, so there is a series of auxiliary equipment the transformer body outside to guarantee its safe operation, these auxiliary equipments comprise monitored meter, oil circulation pipe, cooling system etc.Need to lay from the transformer top new lead-out wire and introduction pipe while drawing under Transformer Bushing Tap, lead-out wire is positioned at introduction pipe, this just requires the laying of introduction pipe not only want firm, reliable but also want rational and orderly, the operation of other servicing units is not constituted a threat to.And prior art can not meet above-mentioned requirements.

The utility model content

The shortcoming existed in order to overcome above-mentioned prior art, the purpose of this utility model is to provide a kind of Transformer Bushing Tap deriving structure, the laying of its introduction pipe is not only wanted firm, reliable but also is wanted rational and orderly, the operation of other servicing units is not constituted a threat to.

The technical solution of the utility model is: the Transformer Bushing Tap deriving structure, comprise introduction pipe, described introduction pipe is drawn joint from end shield and is drawn, and described introduction pipe is drawn joint from end shield and caused the gap between transformer body and radiator downwards; At the rising seat flange of transformer, described introduction pipe is fixed on the rising seat flange of transformer by the first pipeline fixing bracket; Below the rising seat of transformer, described introduction pipe is fixed on the radiator oil pipe flange of transformer with the second pipe fixed support; Described introduction pipe is caused the cat ladder place of transformer by the radiator oil pipe flange level of transformer; Described introduction pipe completes right-angled bend by the 3rd pipeline fixing bracket makes direction vertically downward, and is connected to the end shield ground plate place of the cat ladder rear side of transformer.

The beneficial effects of the utility model are: the laying of its introduction pipe is not only wanted firm, reliable but also is wanted rational and orderly, the operation of other servicing units is not constituted a threat to.

The accompanying drawing explanation

Below in conjunction with drawings and Examples, the utility model is described further:

Fig. 1 is vertical view of the present utility model;

Fig. 2 is right view of the present utility model;

Fig. 3 is the part-structure schematic diagram in Fig. 2;

In figure: 1 introduction pipe, 2 end shields are drawn joint, 3 transformer bodies, 4 radiators, 5 rising seats, 6 first pipeline fixing brackets, 7 rising seat flanges, 8 second pipe fixed supports, 9 radiator oil pipe flanges, 10 cat ladders, 11 the 3rd pipeline fixing brackets, 12 end shield ground plates.

Embodiment

As shown in Figure 1, 2, 3, this Transformer Bushing Tap deriving structure, comprise introduction pipe 1, described introduction pipe 1 is drawn joint 2 from end shield and is drawn, and described introduction pipe 1 is drawn joint 2 from end shield and caused the gap between transformer body 3 and radiator 4 downwards;

At rising seat flange 7 places of transformer, described introduction pipe 1 is fixed on the rising seat flange 7 of transformer by the first pipeline fixing bracket 6;

Below the rising seat 5 of transformer, described introduction pipe 1 use second pipe fixed support 8 is fixed on the radiator oil pipe flange 9 of transformer;

Described introduction pipe 1 is caused cat ladder 10 places of transformer by radiator oil pipe flange 9 place's levels of transformer; Described introduction pipe 1 completes right-angled bend by the 3rd pipeline fixing bracket 11 makes direction vertically downward, and is connected to end shield ground plate 12 places of cat ladder 10 rear sides of transformer.

The laying of the introduction pipe of this Transformer Bushing Tap deriving structure is not only wanted firm, reliable but also is wanted rational and orderly, the operation of other servicing units is not constituted a threat to.

Claims

1. the Transformer Bushing Tap deriving structure, comprise introduction pipe, and described introduction pipe is drawn joint from end shield and drawn, and it is characterized in that, described introduction pipe is drawn joint from end shield and caused the gap between transformer body and radiator downwards; At the rising seat flange of transformer, described introduction pipe is fixed on the rising seat flange of transformer by the first pipeline fixing bracket; Below the rising seat of transformer, described introduction pipe is fixed on the radiator oil pipe flange of transformer with the second pipe fixed support; Described introduction pipe is caused the cat ladder place of transformer by the radiator oil pipe flange level of transformer; Described introduction pipe completes right-angled bend by the 3rd pipeline fixing bracket makes direction vertically downward, and is connected to the end shield ground plate place of the cat ladder rear side of transformer.
