Description

Single-phase powder core conjugation reactor

Technical field

The utility model relates to the AC reactor being applied to ac filter system (LCL), particularly single-phase powder core conjugation reactor.

Background technology

Current large power power electronic appliance filter circuit is conventional is LCL circuit, to resisting high order harmonic component successful, reactor (L) product of traditional LCL filtering generally adopts silicon steel sheet and two reactor tandem plans, coil adopt lenticular wire flat around or the shortcoming such as foil coiling also exists that core loss is high, noise is large and volume is large.Along with the high speed development of high-power electric and electronic, the proportion of LCL filter circuit cost and loss whole system is increasing, and wherein two reactor L are account for filter total cost 80%, so the design of two reactor L is crucial.

Utility model content

Technical problem to be solved in the utility model is for the deficiency existing for prior art and provides a kind of single-phase powder core conjugation reactor, this single-phase powder core conjugation reactor by integrated two reactors reducing iron core consumption (share a yoke), change the winding mode of coil with increasing heat radiation area with reduce eddy current loss, thus reduce material usage and loss.

Technical problem to be solved in the utility model can be achieved through the following technical solutions:

Single-phase powder core conjugation reactor, comprise the first reactor and the second reactor, wherein the first reactor becomes upper and lower mode permutation and combination with the iron core in the second reactor, lower yoke in described first reactor and the upper yoke in the second reactor share, and the iron core of described first reactor and the second reactor adopts the Fe-Si-Al magnetic heart to be prepared from.

In a preferred embodiment of the present utility model, the iron core of described first reactor and the second reactor adopts upper and lower folder and is fitted together by the securing member that upper and lower folder couples together.

In a preferred embodiment of the present utility model, the iron core of described first reactor and the iron core of the second reactor include upper yoke, lower yoke and connect two stem stems between upper and lower iron yoke, and upper and lower iron yoke and Liang Gen center pinch form a square shape iron core.

In a preferred embodiment of the present utility model, described first reactor and the second reactor all also comprise a coil, and described coil is divided into upper and lower nodel line circle, are electrically connected between upper and lower nodel line circle by bus-bar.

In a preferred embodiment of the present utility model, described upper and lower nodel line circle all adopts aluminum steel to be wound on two mandrels around mode so that 8-shaped is vertical.

Owing to have employed technique scheme, the utility model and prior art (silicon sheet core, two independent reactors) are compared, and have the following advantages: 1) loss reduces by more than 20%; 2) weight saving more than 30%; 3) global reliability improves more than 10%.
