Description

A kind of contact is decided the electric current linear Regulatable reactor of connecting

Technical field

The utility model relate to a kind of under electriferous state by brush or charcoal wheel contact coil, the change coil turn, what reach that inductive reactance can continuously smooth regulates decides the electric current linear Regulatable reactor of connecting.

Background technology

So far as the Regulatable reactor of band point continuous stepless smooth change, generally all need to combine with the additional constant reactance device of voltage regulator in the electric product market.For example: the patent No. is the Regulatable reactor of the charged continuous adjusting of ZL200620043446.3; The patent No. is a kind of tandem type tunable load of ZL201120013827.8; The patent No. has the three-phase Regulatable reactor of linear and non-linear speciality etc. when being ZL201120410280.5, they all by voltage regulator regulate secondary with the reactive power of constant reactance device inductive load, thereby the equivalent inductive reactance that makes the elementary stiff of voltage regulator or current source receive changes, and realizes the reactance variable adjustable.

Summary of the invention

The purpose of this utility model provide a kind of under electriferous state reactance can be continuously and the contact of smooth change decide the electric current linear Regulatable reactor of connecting.

To achieve these goals, the technical solution of the utility model is: a kind of contact is decided the electric current linear Regulatable reactor of connecting, comprise iron core, it is characterized in that in iron core, adding dielectric, be wound with coil on the described iron core, described coil has exposed outer surface, and described coil outer surface is provided with the adjustable contact that cooperates with it.When described iron core is annular core, radially embed insulation spacer along described annular core, described adjustable contact is the brush that is slidingly connected with the coil outer surface.When described iron core is the upright post type iron core, embed insulation spacer in the cross section of described iron core, described adjustable contact is the charcoal wheel that rolls and be connected with the coil outer surface.The thickness of above-mentioned insulation spacer is 0.1 ~ 20m.Single Regulatable reactor constitutes single-phase Regulatable reactor; Three Regulatable reactor constitute the three-phase Regulatable reactor.

With the contacting of coil, change coil turn, thereby inductive reactance is changed thereupon when the utility model adopts brush to move or the charcoal wheel rolls, realize the adjusting variation of reactance 0 ~ 100% design load.It can be series in the various circuit, makes the electric current of circuit, and reactive power and power factor are regulated widely.The utility model is different from existing Regulatable reactor, does not need additional any constant reactance device load, and it is variable that direct voltage variable with voltage regulator is converted into reactance.Owing to belong to linear inductance, it can be connected in any circuit, can not cause the wave distortion of electric current and voltage, also can not produce electrical network and disturb.The utility model can be made into single-phase product, also can be made into the three-phase product.

Embodiment

Below in conjunction with accompanying drawing and example the utility model is elaborated.

A kind of contact is decided the electric current linear Regulatable reactor of connecting, and comprises iron core 1, it is characterized in that adding in iron core insulation spacer 2, and this insulation spacer 2 is used for getting involved the magnetic loop of described iron core along arranging perpendicular to described iron core magnetic loop direction.Be wound with coil on the described iron core 1, described coil has exposed outer surface, and described coil outer surface is provided with the adjustable contact that cooperates with it, and described adjustable contact contacts with the exposed outer surface of coil, and its contact point is called moving some x.When adjustable contact moves, just formed a Regulatable reactor that is constituted by number of turn variation between this moving some x and winding head or the coil tail.

The utility model utilizes existing variable-voltage transformer to comprise the annular core of single-phase or three-phase or the variable-voltage transformer of upright post type iron core.

As shown in Figure 1, in the actual fabrication of annular core, original annular core 1 must be cut along the radial direction of this annular core 1, then insulation spacer 2 be embedded.After iron core carried out insulation processing, by the Regulatable reactor designing requirement, coiling was also installed brush again.At last by the requirement of Fig. 1, winding head A1, coil tail A and brush are picked out an X1 cause and terminal board occurs.The actual reactance X that seals in circuit _LWith maximum reactance X _MaxPercent value and this Fig. 1 in winding head A1 with and moving some x contacting of brush 3 between accent journey distance L and square being directly proportional of the ratio of the coil total length between winding head A1 and the coil tail A.Therefore by regulating brush 3 positions, change the position of moving some x, can realize the regulative reactance X of 0 ~ 100%Xmax _L, I _LFor flowing through regulative reactance X _LElectric current I _LWhen concrete series connection was used, available winding head A1 and brush picked out two terminals of an X1, and also available coil tail A and brush pick out two terminals of an X1, and the adjusting direction of the two is just in time opposite, and one is clockwise adjusting, and another is counterclockwise adjusting.

In the actual fabrication of upright post type iron core, embed insulation spacer 2 at the place, cross section of column iron core column 5, except coil was pressed reactor designing requirement coiling, other charcoal wheels were installed insulating treatment process with the pillar variable-voltage transformer.At last by shown in Figure 2, equally winding head A1, coil tail A and charcoal wheel picked out an X2 and cause and terminal board occurs.The actual reactance X that seals in circuit _LWith maximum reactance X _MaxPercent value and this Fig. 2 in winding head A1 with and charcoal wheel 4 moving some x that contact between accent journey distance L and square being directly proportional of the ratio of the coil total length between winding head A1 and the coil tail A.Therefore by regulating the position of charcoal wheel 4, change the position of moving some x, can realize the regulative reactance X of 0 ~ 100%Xmax _LWhen concrete series connection was used, available winding head A1 and charcoal wheel picked out two terminals of an X2, and also available coil tail A and charcoal wheel picks out two terminals of an X2, and the adjusting direction of the two is just in time opposite, and one is up adjusting, and another is descending adjusting.
