Abstract
The utility model discloses a single core column and single coil adjustable reactor, which comprises an iron core column and a coil.The iron core column is a long iron core without gas in the middle thereof.The length of the iron core column is slightly longer than that of the coil.The inductance is adjusted by regulating the distance between the end of the iron core column and the coil.
Description
Technical field
The present invention relates to a kind of single-phase series iron core reactor, especially be used in the reactive power compensation or filter that cooperates with capacitor.
Background technology
At present in the reactive power compensation or filter that is used with capacitor, the reactor of configuration is generally three-phase reactor, by iron core column, coil and on lower yoke form.Iron core column is made up of segment core, is added with air gap between per two iron leg cores.Finely tune the inductance value of reactor by adjusting air gap length.Because the iron core segmentation will cause unavoidable noise; Air gap between the segment core also is unfavorable for the heat conduction between the iron core; The structure of traditional reactor is relatively complicated in addition, and weight ratio is bigger, has increased the weight of whole device, and cost still is on the higher relatively level.
Summary of the invention
In order to solve the noise problem of existing reactor preferably, optimize the structure of reactor, effectively reduce the cost of reactor.The invention provides a kind of single-phase half core adjustable series reactor, can effectively reduce the noise of reactor, simplify the production technology of reactor, thereby reduce cost.
For achieving the above object, the utility model is by the following technical solutions:
Select for use elongated iron core to replace segmentation to add the iron core of air gap, thus can be effectively than the noise problem of hanging down reactor.Every single-phase reactor is made up of an iron core column and single coil, the length of iron core column is slightly longer than the length of coil, coil can be free to slide on iron core, regulates inductance value by the distance of regulating winding and core ends, can change the inductance of reactor in a bigger scope.Replace traditional three-phase reactor with three single-phase half core reactors, directly reduced the iron yoke of traditional reactor, thereby reduced cost significantly, alleviated the weight of reactor, and the former is structurally loose than the latter, so heat radiation is better than the latter.
The beneficial effects of the utility model are, can effectively reduce the noise of reactor, make the inductance value of reactor adjustable, simple in structure, loose in a bigger scope, have reduced the cost level of existing reactor.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Embodiment
Be described further below in conjunction with accompanying drawing.
Operation principle of the present utility model and essential implementation are as follows:
Referring to Fig. 1, on elongated iron core Fe, length of coiling slightly is shorter than the coil N of iron core, the distance of two ends of coil distance iron core is respectively L1 and L2, coil can slide on iron core, along with the slip of coil, the size of L1 and L2 will change, and inductance value can be adjustable in a bigger scope so.Core interior is not established air gap, can effectively reduce the noise of reactor; Simple in structure, loose, can effectively improve heat dissipation environment.
