Abstract

The utility model discloses a core lamination reactor, which comprises an I-shaped core lamination, an E-shaped iron core lamination and a coil packet, wherein the coil packet is enwound in the E-shaped iron core lamination; the I-shaped iron core lamination and the E-shaped iron core lamination are welded together; a gap exists between the middle part of the E-shaped iron core lamination and the I-shaped iron core lamination. The reactor has the advantages that the E-shaped iron core lamination and the I-shaped iron core lamination are welded into a whole, so that a fixing framework is spared, the production process is simplified and the manual cost is saved.

Description

A kind of core lamination reactor

Technical field

The utility model relates to a kind of reactor, especially relates to a kind of core lamination reactor.

Background technology

Reactor is to rely on the induction reactance of coil to hinder the electrical equipment that electric current changes.A kind of core lamination reactor is arranged, and it comprises E core lamination, I core lamination and coil bag, and E core lamination and I core lamination are fixed up by clamping plate, and coil surrounds on the skeleton.There is following shortcoming in present EI lamination reactor: structure is complicated, electric property is unstable, and the production technology trouble can be sent bigger noise, line bag temperature height during unshakable in one's determination work.

Summary of the invention

Technical problem to be solved in the utility model provides that a kind of simple in structure, electric property is stable, the less core lamination reactor of noise during work.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of core lamination reactor, comprise I core lamination, E core lamination and coil bag, described coil looping is in described E core lamination, described I core lamination and described E core lamination weld together, and have the gap between the mid portion of described E core lamination and the described I core lamination.

Described coil packet portion ties with adhesive tape, and described coil packet portion is exposed.

In the gap between described E core lamination and the I core lamination filler is set.

Described coil bag is drawn two binding posts.

Compared with prior art, advantage of the present utility model is that E core lamination and I core lamination are welded into an integral body, has saved fixed frame, has simplified and has given production technology, saves labour turnover.

I core lamination and E core lamination adopt welding manner to fix, and silicon steel sheet in the core lamination and the air gap between the silicon steel sheet are reduced, thereby reduce the noise when work unshakable in one's determination; The coil packet portion is exposed, and coil bag and air directly carry out heat transmission at work, reduces the temperature of reactor when work.Air gap place pad filler between I sheet and E sheet can improve inductance value consistency in batches, the noise when reducing unshakable in one's determination work.
