Description
Technical field
This utility model relates to a kind of power equipment device, in particular for the high Bs nanocrystalline magnet core of transformer.
Background technology
Current transformer is power generation and Domestic electric meter electric energy metrical, the key equipment of protection.Operation of current transformers principle is similar with common transformer: the high voltage of electrical network is converted into low-voltage；Big electric current is converted into small area analysis.But, current transformer is that it has the highest certainty of measurement requirement with an important difference of common transformer.
Magnetic core is the important component part of transformer, and traditional current transformer for metering magnetic core uses ferrite or permalloy to make.Although ferrite and two kinds of soft magnetic materials of permalloy can meet certain metering transformer required precision, but the shortcoming that there is saturation induction density Bs the highest (less than 1.0T) due to ferrite and permalloy, cause transformer global design volume excessive, and, at system jam, reach saturated when electric current increases rapidly, it is impossible to normally work.
Summary of the invention
Problem to be solved in the utility model is, for above-mentioned shortcoming of the prior art, proposes one and has high Bs(more than 1.4T), and there is the magnetic core of high permeability, especially a kind of transformer is with high Bs nanocrystalline magnet core.
For solving the problems referred to above, the scheme that this utility model uses is as follows: a kind of transformer is with high Bs nanocrystalline magnet core, it is characterised in that described transformer includes eight circular arc flap magnetic cores and a hollow cylinder magnetic core set with high Bs nanocrystalline magnet core；Described eight flap magnetic cores are mutually linked one hollow cylinder of composition, and are arranged in magnetic core set；Described flap magnetic core is locked to be sticked with magnetic core and puts.
Further, it is provided with, according to transformer described in above-mentioned design high Bs nanocrystalline magnet core, two sides of described flap magnetic core, the gap mutually agreed with；Described flap magnetic core is mutually linked by gap.
Further, it is provided with magnetic cap according to transformer described in above-mentioned design high Bs nanocrystalline magnet core, the hollow cylinder of described flap magnetic core composition and the two ends up and down of magnetic core set.
Further, according to transformer described in above-mentioned design with high Bs nanocrystalline magnet core, the overall diameter of described magnetic cap is identical with the overall diameter that magnetic core overlaps.
Further, it is provided with female thread according to transformer described in above-mentioned design high Bs nanocrystalline magnet core, the two ends of described flap magnetic core；Described magnetic cap is provided with the external screw thread mated with female thread；Described magnetic cap is threaded connection with flap magnetic core.
Further, high Bs nanocrystalline magnetically soft alloy material is used to make according to transformer described in above-mentioned design high Bs nanocrystalline magnet core, described flap magnetic core.
Further, the solid strip of 0.02～0.04mm thickness is used to make according to transformer described in above-mentioned design high Bs nanocrystalline magnet core, described high Bs nanocrystalline magnetically soft alloy material.
A kind of transformer is with high Bs nanocrystalline magnet core, it is characterised in that described magnetic core is rolled by high Bs Sol-Gel solid strip and forms.
Technique effect of the present utility model is as follows: this utility model uses high Bs nano crystal soft magnetic material to substitute ferrite completely or permalloy makes transformer magnetic core.The nano crystal soft magnetic material used, in addition to having high Bs feature, also has high permeability.Use the transformer magnetic core made by this material can meet measuring accuracy requirement, simultaneously as it has high Bs(more than 1.4T), core volume can be reduced, thus reduce transformer overall volume.Further, the system failure occurring, when electric current increases rapidly, magnetic core will not be rapidly saturated, such that it is able to keep normal operating conditions.
This utility model uses eight flap core combination to become hollow cylindrical structure, and at its outer sheathed magnetic core set, the characteristic of high Bs nano crystal soft magnetic material can be given full play to, make magnetic core of the present utility model can meet measuring accuracy requirement, simultaneously, owing to it has high Bs(more than 1.4T), core volume can be reduced, thus reduce transformer overall volume.Further, the system failure occurring, when electric current increases rapidly, magnetic core will not be rapidly saturated, such that it is able to keep normal operating conditions.
Further, by transformer of the present utility model with high Bs nanocrystalline magnet core, ferrite or permalloy magnetic core in prior art is substituted.Anti-saturation ability in metering transformer application, it is ensured that while measuring accuracy, when reducing transformer global design volume and improve the system failure.
