Abstract
The invention discloses an iron core structure of an electro-slag furnace transformer. The iron core structure comprises an iron core (1) made of a silicon steel sheet and is characterized in that a cavity in the upper part of the iron core (1) is inverted-frustum-shaped, and an included angle formed between an inclined plane and a horizontal plane of the inner wall of the upper part of the iron core (1) is 35-60 degrees. According to the iron core structure, the inverted-frustum-shaped cavity is formed in the upper part of the iron core, so that the magnetic flux direction of the iron core and the rolling direction of the silicon steel sheet are identical, and the loss value during the idle load is decreased. The iron core structure has the characteristics that the structure is simple, convenient to process and suitable for promotion and usage.
Description
Technical field
The present invention relates to a kind of core structure of electroslag furnace transformer.
Background technology
The electroslag furnace transformer is used for specializing in the electroslag furnace power supply that aviation is held steel, high temperature alloy, electric resistance alloy, Precise Alloy, some non-ferrous metal and produced large-scale high duty alloy steel ingot, large-scale slab ingot, slab, other special special-shaped casts etc.The core structure of existing electroslag furnace transformer because it is moulded consistent, causes the rolling direction of its flow direction and silicon steel sheet perpendicular, and loss value is larger when causing zero load.
Summary of the invention
The objective of the invention is the problem that exists for prior art, the rolling direction that a kind of flow direction and silicon steel sheet be provided is identical so that the core structure of the electroslag furnace transformer that loss value reduces when unloaded.
The objective of the invention is to solve by the following technical programs:
A kind of core structure of electroslag furnace transformer comprises the iron core that silicon steel sheet is made, and it is characterized in that the upper cavity of described iron core is down prism-frustum-shaped.
The angle that the inclined-plane of described iron core upper inside wall becomes with horizontal plane is 35 °-60 °.
The present invention has the following advantages compared to existing technology:
The present invention is by arrange the cavity of prism-frustum-shaped on the top of iron core, so that the flow direction of iron core is identical with the rolling direction of silicon steel sheet, reduced the loss value when unloaded, has characteristics simple in structure, easy to process, suits to promote the use of.
Description of drawings
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-iron core.
Embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
As shown in Figure 1: a kind of core structure of electroslag furnace transformer, comprise the iron core 1 that silicon steel sheet is made, it is 35 °-60 ° that the upper cavity of this iron core 1 is down the angle that the inclined-plane of prism-frustum-shaped and iron core 1 upper inside wall becomes with horizontal plane.
The present invention is by arrange the cavity of prism-frustum-shaped on the top of iron core 1, so that the flow direction of iron core is identical with the rolling direction of silicon steel sheet, reduced the loss value when unloaded, has characteristics simple in structure, easy to process, suits to promote the use of.
Above embodiment only for explanation technological thought of the present invention, can not limit protection scope of the present invention with this, every technological thought that proposes according to the present invention, and any change of doing on the technical scheme basis all falls within the protection range of the present invention; The technology that the present invention does not relate to all can be realized by prior art.
Claims (2)
