Abstract

The utility model relates to a novel transformer lead structure which comprises a clamping piece (1), a transformer box cover (2), a high-voltage bushing (3), a voltage-sharing ball (4) of the high-voltage bushing, a high-voltage bushing lead (5), a transformer box wall (6), a lead wire clamp (7), a transformer iron-core (8) and an insulation paper cylinder (9), wherein the insulation paper cylinder (9) is arranged on the periphery of the voltage-sharing ball (4) of the high-voltage bushing and fixed on the lead wire clamp (7). Through adding the insulation surrounding cylinder in a position close to the voltage-sharing ball, the electric-field distribution condition of the voltage-sharing ball is effectively improved, the partial discharge of products is effectively reduced, the insulation distance from the voltage-sharing ball to each part is correspondingly narrowed, and the lead is designed more compactly, thereby saving design costs to a certain degree and increasing the economic benefits.

Description

A kind of transformer lead structure
Technical field
The utility model relates to a kind of pin configuration, relates in particular to a kind of new transformer lead structure, belongs to transformer ' s type product manufacturing technology.
Background technology
In traditional 110kV lead design, because the voltage equalizing ball of bushing is a bare electrode, current potential is higher and local field strength is bigger, and strict size required distance (as shown in Figure 1) is arranged between bushing voltage equalizing ball 4 and folder 1, transformer case lid 2, the transformer tank wall 6, undersizedly bring certain hidden danger will for the safe operation of product, also can cause product office to let slip greatly simultaneously, can't satisfy user's instructions for use.
The utility model content
Technical problem to be solved:
But provide a kind of a kind of transformer lead structure that can effectively guarantee safe operation and decreased distance at above not enough the utility model.
Technical scheme:
A kind of transformer lead structure comprises folder, transformer case lid, bushing, bushing voltage equalizing ball, bushing lead-in wire, transformer tank wall, wire-lead folder, transformer core, it is characterized in that: also comprise insulating paper cylinder, periphery at the bushing voltage equalizing ball is provided with insulating paper cylinder, and insulating paper cylinder is fixed on the wire-lead folder.
Beneficial effect:
The utility model increases an insulation at the position near voltage equalizing ball and encloses tube, and its effect has not only improved its Electric Field Distribution situation effectively; The office that effectively reduces product puts, and also can make its insulation distance to each several part obtain corresponding dwindling, and makes the compact more of lead design, has saved design cost to a certain extent, has improved economic benefit.
Description of drawings
Fig. 1 is the structural representation of existing transformer lead;
Fig. 2 is a structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
As shown in Figure 1 and Figure 2, a kind of transformer lead structure comprises folder 1, transformer case lid 2, bushing 3, bushing voltage equalizing ball 4, bushing lead-in wire 5, transformer tank wall 6, wire-lead folder 7, transformer core 8, insulating paper cylinder 9, be provided with insulating paper cylinder 9 in the periphery of bushing voltage equalizing ball 4, insulating paper cylinder 9 is fixed on the wire-lead folder 7.
Increase insulating paper cylinder 9, can guarantee again under the prerequisite of product safety operation, can suitably dwindle and bushing voltage equalizing ball 4 and folder 1, transformer case lid 2, transformer tank wall 6 between distance between the position, make the compact more of lead design.
Though the utility model with preferred embodiment openly as above; but they are not to be used for limiting the utility model; anyly be familiar with this skill person; in the spirit and scope that do not break away from the utility model; can do various variations or retouching from working as, what therefore protection range of the present utility model should be defined with the application's claim protection range is as the criterion.
