Abstract
The invention discloses a silicon carbide rod transformer. The silicon carbide rod transformer comprises an iron core (1) made of silicon steel sheets and is characterized in that a cavity in the upper portion of the iron core (1) is in the shape of an inverted frustum of a pyramid, and the included angle formed between the bevel of the inner wall on the upper portion of the iron core (1) and the horizontal plane is 37 degrees. According to the silicon carbide rod transformer, the cavity in the shape of the inverted frustum of a pyramid is formed in the upper portion of the iron core and the included angle between the bevel of the inner wall of the upper portion of the iron core and the horizontal plane is set to be 37 degrees, so that the magnetic flux direction of the iron core is the same as the rolling direction of the silicon steel sheets, no-load loss is reduced, and the silicon carbide rod transformer has the advantages of being simple in structure, convenient to machine and suitable for being used and popularized.
Description
Technical field
The present invention relates to a kind of globar transformer.
Background technology
Silicon carbide rod furnace transformer is specialized in the use of the front power supply of silicon carbide rod furnace, Elema calandria in use, resistance value is along with the increase of service time increases, and this phenomenon is called aging, and the aging of rod should be considered as normal phenomenon, after rod is aging, can make furnace temperature reduce, in order normally to work, improve the useful life of Elema, adopt the output voltage that regulates transformer, thereby meet the operating voltage of Elema, the amplitude of accommodation can reach 2-3 times.Existing globar transformer, because it is moulded consistent, causes the rolling direction of its flow direction and silicon steel sheet perpendicular, and while causing zero load, loss value is larger.
Summary of the invention
The object of the invention is the problem existing for prior art, the globar transformer that when rolling direction of a kind of flow direction and silicon steel sheet is identical makes zero load, loss value reduces is provided.
The object of the invention is to solve by the following technical programs:
A kind of globar transformer, comprises iron core, it is characterized in that the upper cavity of described iron core is down prism-frustum-shaped, and the angle that the inclined-plane of iron core upper inside wall becomes with horizontal plane is 37 °.
Described iron core adopts silicon steel sheet to make.
The present invention has the following advantages compared to existing technology:
The present invention arranges the cavity of prism-frustum-shaped by the top at iron core, and the angle that the inclined-plane of setting iron core upper inside wall becomes with horizontal plane is 37 °, make the flow direction of iron core identical with the rolling direction of silicon steel sheet, reduce the loss value when unloaded, there is feature simple in structure, easy to process, suitable promoting the use of.
Brief description of the drawings
Accompanying drawing 1 is structural representation of the present invention.
Wherein: 1-iron core.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further illustrated.
As shown in Figure 1: a kind of globar transformer, comprise the iron core 1 that silicon steel sheet is made, it is 37 ° 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 arranges the cavity of prism-frustum-shaped by the top at iron core 1, and the angle that the inclined-plane of setting iron core upper inside wall becomes with horizontal plane is 37 °, make the flow direction of iron core identical with the rolling direction of silicon steel sheet, reduce the loss value when unloaded, there is feature simple in structure, easy to process, suitable promoting 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 proposing according to the present invention, and any change of doing on technical scheme basis, within all falling into 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)
1. a globar transformer, comprises iron core (1), it is characterized in that the upper cavity of described iron core (1) is down prism-frustum-shaped, and the angle that the inclined-plane of iron core (1) upper inside wall becomes with horizontal plane is 37 °.
2. globar transformer according to claim 1, is characterized in that described iron core (1) adopts silicon steel sheet to make.
