Abstract
The utility model discloses a novel current transformer. The novel current transformer comprises a main body, as well as an iron core and a primary conductor which are arranged in the main body, and is characterized in that the iron core is an ultracrystalline alloy iron core. The transformer cast by the ultracrystalline iron core with high magnetic permeability has a small measuring error and high precision and can substantially meet the error consistency of high volume products; and the ultracrystalline alloy iron core is light in weight, small in size and good in insulation, and can better meet the miniaturization and light-duty development tendency of transformers.
Description
Technical field
The utility model relates to a kind of novel current transformer, belongs to electronic device field.
Background technology
General current transformer is measured the level winding and is all adopted silicon steel sheet to roll the iron core that forms, and the not only magnetic permeability of this silicon sheet core is low, and the height of magnetic permeability causes error not guarantee, the error of bulk article can not guarantee in full accord.
The utility model content
The technical problem that the utility model solves is to provide a kind of current transformer that adopts magnetic iron core.
The technical solution that realizes the utility model purpose is:
A kind of novel current transformer, the iron core and the Primary Conductor that comprise body and be arranged on body interior is characterized in that: described iron core is nanocrystalline alloy cores.
The utility model adopts nanocrystalline alloy cores, the magnetic permeability of this iron core is high, water that the measurement error of transformer that outpours is little, precision is high, substantially can satisfy the consistent of bulk article error, and the nanocrystalline alloy cores quality is light, volume is little, good insulating, more can satisfy the development trend of instrument transformer miniaturization, lightness.
Description of drawings
Fig. 1 is structural representation of the present utility model;
The implication of number in the figure representative is: 1. body, 2. iron core, 3. Primary Conductor.
Embodiment
As shown in Figure 1, a kind of novel current transformer, the iron core 2 and the Primary Conductor 3 that comprise body 1 and be arranged on body 1 inside, described iron core 2 is nanocrystalline alloy cores.
The utility model adopts nanocrystalline alloy cores, the magnetic permeability of this iron core is high, water that the measurement error of transformer that outpours is little, precision is high, substantially can satisfy the consistent of bulk article error, and the nanocrystalline alloy cores quality is light, volume is little, good insulating, more can satisfy the development trend of instrument transformer miniaturization, lightness.
Below schematically the utility model and execution mode thereof are described, this description does not have restricted, and shown in the accompanying drawing also is one of execution mode of the present utility model, and actual structure is not limited to this.So, if those of ordinary skill in the art is enlightened by it, create aim in the situation that do not break away from the utility model, without the creationary frame mode similar to this technical scheme and the embodiment of designing, all should belong to protection range of the present utility model.
