Abstract
The invention relates to a clamping structure for a tapping lead of a transformer, in particular to a clamping structure for a high voltage tapping lead of a transformer. The clamping structure comprises a pressure plate arranged above a coil, a supporting plate arranged below the coil, and a clamping column arranged between the pressure plate and the supporting plate and used for fixing the tapping lead and leading the tapping lead to a switch; the pressure plate comprises a first body covering the coil from the axial direction of the transformer and a first connecting part extending outwards from the first body; the supporting plate comprises a second body covering the coil from the axial direction of the transformer and a second connecting part extending outwards from the second body; and the clamping column is used for connecting the first connecting part with the second connecting part. The purpose of the invention is to provide a clamping structure with the advantages of less parts, simple structure and convenience in installation.
Description
Technical field
The present invention relates to a kind of transformer tapping lead clamp structure, particularly a kind of transformer high-voltage tap lead clamp structure.
Background technology
When the structure of Design of Transformer, how it being caused the position of the switch after the high-voltage tap lead of transformer is drawn from coil also is a worth research and improved field.When high-voltage tap lead is caused switch, also need consider how in limited space, to make arranging both rationally to have and having enough intensity of tap lead, avoid producing potential safety hazard.In the prior art, because the pressing plate of coil and supporting plate are circular, and consider the material cost problem, pressing plate and supporting plate be general identical with coil perpendicular to the area of section of transformer axial direction.Therefore can only be at upper and lower folder welding support plate and the angle steel of transformer, between the support plate of upper and lower folder and angle steel, the framework that holder forms a tap lead is set, high-voltage tap lead is fixed and is caused switch by this framework.Can find out that above-mentioned clamp structure parts are many, the comparatively inconvenience of complex structure, installation.
Summary of the invention
For the problems referred to above, the invention provides a kind of transformer tapping lead clamp structure, its parts are few, simple in structure, easy for installation.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of transformer tapping lead clamp structure, comprise the pressing plate, the supporting plate that is arranged at the coil below that are arranged at coil top, be arranged between described pressing plate and the supporting plate and be used for tap lead is fixed and caused the clamp column of switch, described pressing plate comprises from the first noumenon of the axial covering coil of transformer and from outwardly directed the first connecting portion of the first noumenon, described supporting plate comprises that described clamp column links to each other described the first connecting portion with described the second connecting portion from the second body of the axial covering coil of transformer and from outwardly directed the second connecting portion of the second body.
Preferably, described pressing plate is rectangular perpendicular to the axial cross section of transformer.
Preferably, described supporting plate is rectangular perpendicular to the axial cross section of transformer.
Preferably, described pressing plate and described supporting plate are rectangular perpendicular to the axial cross section of transformer, and described clamp column is arranged on the corner position of rectangle.
Preferably, described clamp column clamping is arranged between described the first connecting portion and described the second connecting portion.
The present invention adopts above structure, because pressing plate and supporting plate are rectangle, has the top corner portion of extending outside the coil, can directly between the drift angle of pressing plate and supporting plate, be arranged with clamp column, when device body insulation assembling, the clamp column clamping is arranged on pressing plate and the supporting plate can finishes installation between the drift angle, its parts are few, simple in structure, easy for installation and cost is low, improved production efficiency.
Description of drawings
Fig. 1 is the front view of a preferred embodiment of the present invention.
Fig. 2 is the vertical view of the pressing plate of a preferred embodiment of the present invention.
Among the figure: 1, coil; 2, pressing plate; 21, upper notch; 3, supporting plate; 31, lower notch; 4, clamp column; 5, tap lead.
Embodiment
Below in conjunction with accompanying drawing content of the present invention is elaborated with a kind of preferred embodiment.
Embodiment
With reference to accompanying drawing 1, a kind of transformer tapping lead clamp structure, comprise the pressing plate 2 that is arranged at coil 1 top, be arranged at the supporting plate 3 of coil 1 below, be arranged between described pressing plate 2 and the supporting plate 3 and be used for tap lead 5 is fixing and cause the clamp column 4 of switch, described pressing plate 2 comprises from the first noumenon of the axial covering coil 1 of transformer and from outwardly directed the first connecting portion of the first noumenon, described supporting plate 3 comprises that described clamp column 5 links to each other described the first connecting portion with described the second connecting portion from the second body of the axial covering coil 1 of transformer and from outwardly directed the second connecting portion of the second body.
In the present embodiment, pressing plate 2 and supporting plate 3 are rectangular perpendicular to the axial cross section of transformer.Be pressing plate 2 and supporting plate 3 when covering coil, its four drift angles extend outside the coil.Offer notch 21 on two drift angles of pressing plate 2 the same sides, offer lower notch 31 at supporting plate 3 two corresponding drift angles.
When transformer body insulating assembles, the upper/lower terminal of clamp column 4 is stuck in corresponding upper notch 21 and the lower notch 31.The tap lead 4 that colligation is good is fixed on the clamp column by bolt assembly and causes the position of the switch.
Owing to can utilize the angle of rectangular platen and supporting plate, directly between it, connect clamp column is set, need not be at upper and lower folder welding support plate and the angle steel of transformer, do not need by bolt clamp column to be fastened between support plate and the angle steel yet, greatly improved production efficiency, transformer tapping lead of the present invention add hold the structure parts still less, cost is lower, it is more convenient to install.
In the present invention, the noun of locality that more than relates to, as shown in Figure 1, the axial direction of this transformer is the longitudinal direction of paper.
Above-described embodiment for explanation technical conceive of the present invention and characteristics, is a kind of preferred embodiment only, and its purpose is to allow the personage who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.The equivalence that all Spirit Essences according to the present invention are done changes or modifies, and all should be encompassed within protection scope of the present invention.
