Problems solved by technology

[0003] Some amorphous alloy magnetic materials have good electromagnetic properties, but their strength and willfulness are insufficient, so the external protection structure is extremely important. The external protection structure of a current transformer using an amorphous alloy core usually has two layers of protection structure, one layer is non-crystalline Crystal alloy magnetic insulation shell, the first layer is the overall protective shell of the transformer; therefore, the overall assembly workload of the amorphous alloy current transformer is relatively large, and it is necessary to design a more convenient assembly structure to improve efficiency

Description

Technical field [0001] The invention relates to the technical field of precision transformer products, in particular to an amorphous alloy current transformer that is easy to assemble. Background technique [0002] The miniaturization of high-precision transformer cores, current transformer cores, and voltage transformer cores depends on the development of new soft magnetic materials with high saturation magnetic induction. Traditional transformer cores, current transformer cores, and voltage transformer cores are usually made of silicon steel sheets. The advantage of silicon steel sheets is that they have high saturation magnetic induction. The disadvantage of silicon steel sheets is that they are relatively large when used in high-frequency fields. The loss, and the magnetic flux density is low. With the continuous development and improvement of iron-based amorphous alloy materials, it fully meets the development requirements for the miniaturization of transformer cores, curre...
