Description

A kind of amorphous reactor

Technical field

The utility model relates to reactor technical field, particularly relates to a kind of amorphous reactor.

Background technology

Reactor is also inductor, and its principle is: the certain space scope occupied by it will produce magnetic field during a conductor energising, so the electric conductor of all energy current-carrying has perception in general sense.But the inductance of the long straight conductor that is energized is less, the magnetic field produced is not strong, and therefore actual reactor is that wire is coiled into solenoid form, claims air core reactor; Sometimes in order to allow this solenoid have larger inductance, just inserting unshakable in one's determination in solenoid, claiming iron-core reactor.

The reactor of prior art generally comprises iron core and coil, and reactor extensively adopts the iron core reactor of band air gap, but the inductance value of the iron core reactor of band air gap can change along with the size of On current, and inductance value is non-constant.

In addition, the high frequency characteristics of the ordinary reactors of prior art is poor, and loss is also larger.

Summary of the invention

The purpose of this utility model is avoid weak point of the prior art and provide a kind of amorphous reactor, and the loss of this amorphous reactor is little.

The purpose of this utility model is achieved through the following technical solutions:

There is provided a kind of amorphous reactor, comprise amorphous and close magnet ring and coil, described amorphous closes magnet ring and comprises inner ring and outer shroud, described coil winding in described inner ring, and between described inner ring and outer shroud.

It is annulus that described amorphous closes magnet ring.

It is straight-flanked ring that described amorphous closes magnet ring.

Described outer shroud comprises semi-ring and lower semi-ring, and described upper semi-ring and second latch closure close.

Described inner ring and outer shroud form by the iron-based non-crystalline band winding up of surface insulation.

Described coil comprises termination, and described termination exposes to described amorphous and closes magnet ring.

the beneficial effects of the utility model:the utility model comprises amorphous and closes magnet ring and coil, and described amorphous closes magnet ring and comprises inner ring and outer shroud, described coil winding in described inner ring, and between described inner ring and outer shroud.

(1) by magnet ring is set to inner ring and outer shroud, coil winding is in inner ring and between inner ring and outer shroud, the length of magnetic circuit is shortened, can coil turn be reduced, reduce thermal losses, also make the effective area of magnetic circuit become large, also can reduce coil turn, reduce thermal losses further.

(2) by magnet ring is set to closed magnet ring, compared with the iron core reactor of the band air gap of prior art, its inductance value can not change along with the size of On current, and inductance value is constant.

(3) the amorphous magnet ring by adopting non-crystalline material to make, has good high frequency characteristics.

Embodiment

With the following Examples the utility model is further described.

A kind of amorphous reactor of the present embodiment, as depicted in figs. 1 and 2, comprise amorphous and close magnet ring and coil, described amorphous closes magnet ring and comprises inner ring and outer shroud, described coil winding in described inner ring, and between described inner ring and outer shroud.

It is straight-flanked ring that described amorphous closes magnet ring, and the shape of magnet ring can be arranged according to actual needs, is not limited to straight-flanked ring, also can be set to annulus, as shown in Figure 3 and Figure 4.

Described outer shroud comprises semi-ring and lower semi-ring, and described upper semi-ring and second latch closure close, convenient for assembly.

Described inner ring and outer shroud form by the iron-based non-crystalline band winding up of surface insulation, have good high frequency characteristics.

Described coil comprises termination, and described termination exposes to described amorphous and closes magnet ring, conveniently connects external pin or external circuit.

The present embodiment has the following advantages:

Finally should be noted that; above embodiment is only in order to illustrate the technical solution of the utility model; but not the restriction to the utility model protection range; although done to explain to the utility model with reference to preferred embodiment; those of ordinary skill in the art is to be understood that; can modify to the technical solution of the utility model or equivalent replacement, and not depart from essence and the scope of technical solutions of the utility model.
