Abstract

The utility model relates to a fixing device for leading wires of a high-voltage transformer. The fixing device is characterized in that vertical wood of a leading wire support is made of laminated wood; a groove of a U-shaped insulating cardboard is stuck outside the vertical wood; a partial area outside the vertical wood is wrapped to a certain degree to increase creepage distances of the leading wires; a U-shaped wood piece is vertically fixed at one side of the vertical wood by insulating bolts; and after the leading wires penetrate through inside space of the U-shaped wood piece, the leading wires and the U-shaped wood piece are held tightly to fix the leading wires by an additional insulating piece. The fixing device for the leading wires of the high-voltage transformer has following beneficial effects: 1, the vertical wood is produced by laminated wood without discharging and hot-pressing processes, thereby having advantages of low cost and high production efficiency; 2, without no groove required in the vertical wood, mechanical strength of the wood piece is improved and the short-circuit-resistance capability of the transformer is enhanced; 3, the U-shaped wood piece, as a commonly-used piece, is used conveniently, thus boosting production efficiency.

Description

A kind of high voltage transformer wire fixture
Technical field
The invention belongs to field transformer, relate to a kind of high voltage transformer wire fixture.
Background technology
Present stage, the large-scale high voltage transformer wooden part that goes between, creepage in order to prevent from going between, standing tree adopts laminated paper board manufacture, need to pass through the operations such as blanking, hot pressing, and complex procedures, production efficiency is low, cost is high; And slot on standing tree, add the cover plate clamping that will go between, but this structure, because have groove on standing tree, makes the large high attenuation of mechanical strength of standing tree; In the time that transformer runs into sudden short circuit, be easy to fracture, cause transformer to damage.
Summary of the invention
The present invention is in order to make up the deficiencies in the prior art, and a kind of simple to operate, easy to use, production efficiency is high, cost is low high voltage transformer wire fixture is provided.
The present invention is achieved through the following technical solutions:
High voltage transformer wire fixture of the present invention, it is characterized in that: the standing tree of down-lead bracket adopts that lamination is wooden to be made, the groove of " U " shape insulating board is stuck in to standing tree outside, a part of region outside standing tree is formed to parcel to a certain degree, increase the creepage distance going between; " U " shape wood part is vertically fixed on to standing tree one side with insulated bolt, between " U " shape wood part inner side and standing tree, form the space that holds lead-in wire, to go between from " U " shape wood part inner space passes, with supplementary insulation part will go between and " U " thus the wooden part stretching of shape lead-in wire is fixed.
The invention has the beneficial effects as follows, 1. standing tree uses that lamination is wooden makes, and cost is low, does not need through the operation such as blanking, hot pressing, and production efficiency is high.2. need on standing tree, not slot, increase the mechanical strength of wooden part, improve the anti-short circuit capability of transformer.3. " U " shape wood part can be used as general part, easy to use, has improved production efficiency.
Brief description of the drawings
Lower Fig. 1,2 is respectively front view of the present invention, left view schematic diagram, front view, left view schematic diagram that lower Fig. 3,4 is traditional structure.
In Fig. 1: 1 lead-in wire, 2, insulated bolt, 3, " U " shape insulating board, 4, standing tree, 5, " U " shape wood part.
In Fig. 4: 6, cover plate.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present invention.
High voltage transformer wire fixture of the present invention, the standing tree of down-lead bracket adopts that lamination is wooden to be made, the groove of " U " shape insulating board 3 is stuck in to standing tree 4 outsides, a part of region outside standing tree is formed to parcel to a certain degree, increase the creepage distance of lead-in wire; Again " U " shape wood part 5 use insulated bolts 2 are vertically fixed on to standing tree 4 one sides, between " U " shape wood part inner side and standing tree, form the space that holds lead-in wire, to go between again 1 from " U " shape wood part inner space passes, with supplementary insulation part will go between and " U " thus the wooden part stretching of shape lead-in wire is fixed.
High voltage transformer wire fixture of the present invention, by place " U " shape insulating board on standing tree, increases the creepage distance of lead-in wire, therefore standing tree can be made with lamination is wooden; Directly with " U " shape wood part, lead-in wire is blocked, need on standing tree, not slot, increased the mechanical strength of wooden part.

Claims (1)

1. a high voltage transformer wire fixture, it is characterized in that: the standing tree of down-lead bracket adopts that lamination is wooden to be made, the groove of " U " shape insulating board is stuck in to standing tree outside, a part of region outside standing tree is formed to parcel to a certain degree, increase the creepage distance going between; " U " shape wood part is vertically fixed on to standing tree one side with insulated bolt, between " U " shape wood part inner side and standing tree, form the space that holds lead-in wire, to go between from " U " shape wood part inner space passes, with supplementary insulation part will go between and " U " thus the wooden part stretching of shape lead-in wire is fixed.
