Abstract

The utility model discloses a mutual-inductance power reactor, which changes a conventional structure with a phase and a coil and makes a phase reactor into two coils sheathed together or one phase and two coils overlapped together. Thus the utility model can effectively reduce power consumption by 30 %, decrease cost by 15% and extend service life by 2-3 times.

Description

The mutual inductance type power reactor

The utility model relates to a kind of power reactor, belongs to High-Voltage Electrical Appliances.

The power reactor that is loaded on line outlet at present is mainly used in limiting short-circuit current, existing electric power power reactor is a phase one coil, has only self-induction, and there is not mutual inductance, can not produce the induction effect of its coil to this coil, thereby also can not produce additional reactance from effect, effective reactance value so just can not get compensation.

The purpose of this utility model just provides a kind of mutual inductance type power reactor, and it can produce a part of mutual inductance reactance and compensate total reactance, thereby reduces manufacturing cost, reduction power consumption.

The purpose of this utility model is achieved in that the mutual inductance type power reactor is made up of coil rack and coil, coil rack is made up of interior loop skeleton and exterior loop skeleton suit, on the interior loop skeleton, be wound with the L1 reactor winding, be wound with the L2 reactor winding on the exterior loop skeleton.Reactor can also be to be wound with two or more coils in the same way on a coil rack, then these coil same polarities is linked together and forms.

The utility model changes the traditional structure of a circle mutually, with a phase reactor be made into two mounting coils together or one mutually two coils overlap, thereby the utility model can effectively reduce power consumption 30%, reduces cost 15%, 2～3 times of life-savings.

Below in conjunction with accompanying drawing the utility model is further described:

Fig. 1: mutual inductance type power reactor structural representation;

Among the figure: 1-interior loop skeleton, 2-exterior loop skeleton, 3-L1 reactor exterior loop,

The 4-L2 reactor winding;

The mutual inductance type reactor is made up of interior loop skeleton 1 and exterior loop skeleton 2 suits, be wound with the L1 reactor winding on the interior loop skeleton 1, be wound with the L2 reactor winding on the exterior loop skeleton 2, can maintain a certain distance between the coil, can be zero distance also, be about to two or more coils on same support.Experimental result shows that the distance between coil is short more, and mutual inductance is big more, and the reactance value of corresponding performance is also big more, and is maximum with the zero distance.Like this, total be exactly the reactance mutual inductance reactance that reflects adds the self-induction reactance, because the generation of mutual inductance reactance is invisible, so just can utilize the mutual inductance reactance to replace or during the original single coil structure of a compensation part, the reactance that must produce by self-induction, thus power consumption and manufacturing cost under same effect, reduced.Utilize a part of self-induction reactance of the common reactor of the comprehensive reactance compensation of mutual inductance type reactor, to reduce power consumption and manufacturing cost.
