Abstract

The utility model discloses a power transformer framework and relates to a power transformer support device. Support ribs are added to the upper and lower sides inside the iron core window of the transformer framework, and slopes are added to the upper and lower sides outside the window. An enameled wire passing groove is formed in the lead groove in the upper end of the transformer framework. The power transformer framework has the advantages that the problem of transformer burnout caused by high and low voltage breakdown short circuit at the input end of the transformer is solved, the problems that no-load current and loss are increased, the transformer generates heat, aging is accelerated, the service life is reduced and burnout occurs due to loosening and deformation of an iron core are solved, manual patching is avoided, labor force is liberated greatly, production cost is lowered, and raw material is saved.

Description

Power transformer skeleton

Technical field

The utility model relates to a kind of power transformer bracing or strutting arrangement.

Background technology

At present, known power transformer is mostly 220V input or 380V input, input has two end points, an end points is 0V, and an end points is 220V or 380V, and two end-point voltages are poor is 220V or 380V, be easy to cause high-low pressure to puncture, burn transformer, in order to prevent burning apparatus, adopt artificial Continuous pressing device for stereo-pattern to increase insulation and avoid puncturing or filling the scraps of paper.Transformer framework core window, original skeleton is all right angle, last a slice will lean on people to insert by hand.Because lamination thickness only has 0.5 millimeter, every transformer is with tens, because there being error, not there will be degree of tightness not etc., increased manpower and materials, strengthened manufacturing cost.Existing skeleton cannot be realized transformer input high-low pressure isolation features.

Summary of the invention

The purpose of this utility model is to provide a kind of power transformer skeleton, adopts artificial Continuous pressing device for stereo-pattern increase insulation to avoid puncturing or filling the scraps of paper to solve prior art; There is error in manual inserted sheet, not there will be degree of tightness not etc., increased manpower and materials, strengthened manufacturing cost; Cannot realize the problems such as transformer input high-low pressure isolation features.

The utility model is mainly made up of transformer framework body, solves the technical scheme that its technical problem adopts to be: the inner upper and lower both sides of core window of transformer framework body respectively increase brace rod, and brace rod is protruding triangular form, is highly less than 0.2 millimeter; Increase inclined plane, the outside upper and lower both sides of window, its angle of inclination be 15 degree to 45 degree, can use iron core sheet inserting machine easily to insert; The wire lead slot place of transformer framework upper end arranges enamelled wire crossed beam trunking.

The utility model has mainly solved transformer input high-low pressure puncture short and has caused transformer burnout phenomenon, iron core is because of loosening distortion, no-load current and loss increase, transformer heating. and accelerated ageing, has reduced useful life and burnout phenomenon. solve artificial sticking patch phenomenon.Greatly liberate labour.Reduce production cost, saved raw material.

Adopt good effect of the present utility model be the skeleton of power transformer by not originally being with crossed beam trunking to change band crossed beam trunking into, transformer input winding starting point is drawn in crossed beam trunking, has increased creepage distance, avoids high-low pressure to puncture and burns transformer phenomenon.Insert core window place and change oblique angle into, liberated artificial sticking patch, plug-in sheet machine directly inserts.Add after brace rod, if when the silicon steel sheet tension that transformer is used, utilize silicon steel sheet by brace rod cut-out, ensured the elasticity of iron core, avoided increasing because iron core is out of shape the no-load current causing, loss increases, transformer fever phenomenon.

Brief description of the drawings

Below in conjunction with accompanying drawing and example, the utility model is further illustrated:

Accompanying drawing 1 is the utility model structural representation;

Accompanying drawing 2 is the utility model crossed beam trunking schematic diagram;

Accompanying drawing 3 is the enlarged diagram of the utility model brace rod.

1 crossed beam trunking, 2 inclined planes, 3 brace rods, 4 transformer framework bodies, 5 wire lead slots in figure.

Embodiment

As shown in the figure: the inner upper and lower both sides of core window of transformer framework body 4 respectively increase brace rod 3, and brace rod 3 is protruding triangular form, is highly 0.1 millimeter; Increase inclined plane, the outside upper and lower both sides of window 2, its angle of inclination is 22 degree, can use iron core sheet inserting machine easily to insert; The wire lead slot place of transformer framework 4 upper ends arranges enamelled wire crossed beam trunking 1.
