Electric reactor

Abstract

The invention discloses an electric reactor which comprises an upper iron core, an iron core and a nanocrystalline iron core column arranged between the upper iron core and the lower iron core, wherein the a stretch-resistant layer is coated on the outer layer of the nanocrystalline iron core column which is provided with a plurality of gas gaps. According to the electric reactor, the nanocrystalline iron core column is utilized, the size of a product is reduced, power consumption of the product is reduced, and linearity, consistency and high-frequency direction current carrier resistant performance are improved. The stretch-resistant layer is coated on the outer layer of the stretch-resistant layer through a resin pouring layer, vibration of the electric reactor is reduced obviously, noise is reduced obviously, the resin pouring layer further has good heat resistance performance simultaneously, virtrification temperature of the electric reactor is high, and softening can not occur under 180 DEG C. the fact that the temperature rise cannot achieve the virtrification temperature of the resin pouring layer caused by the heating of the nanocrystalline iron core of the electric reactor, therefore the problem that the resin pouring layer is softened is resolved in essence, and quality of the product of the electric reactor is guaranteed.

Problems solved by technology

[0002] In the traditional design scheme, the overall iron core uses oriented silicon steel sheet, coupled with the limitation of low saturation magnetic density of oriented silicon steel, the actual magnetic density Bm of the reactor is relatively low, so the linearity of the product is poor (generally 1.2 times) , the volume and weight of the product are relatively large, and the cost is relatively high

Reactors made of oriented silicon steel are mainly suitable for low-frequency fields, and only have obvious effects on low-order harmonics. When high-order harmonics or high-frequency DC components exist in the system circuit, the filtering effect of oriented silicon steel reactors is not good. Obvious, and it is easy to generate noise, the iron core column heats up very high, and the power loss increases

Reactors made of oriented silicon steel, in the production process, mostly rely on manual stacking operations, the process is complicated, and the production efficiency is low

[0003] At present, the processing method of oriented silicon steel sheet generally adopts the single sheet stamping method, the burr of the silicon steel sheet is relatively large, and there are unavoidable size errors between the sheets, and in the process of manufacturing the reactor, the method of manual stacking is adopted. The uneven thickness of the final processed block iron core causes the instability of the air gap height of the reactor, so that the consistency of the performance of the reactor is poor
