Description
Technical field
The invention belongs to the high-tension apparatus manufacturing technology, relate in particular to a kind of core type controlled reactor, be mainly used in reactor and make the field.
Background technology
Along with superhigh pressure, long construction and development apart from electrical network, the charging capacity of line-to-ground significantly increases, and the result causes underloading and makes owing to leading reactive power is excessive when unloaded and risen by terminal voltage; Leading current increases power consumption and the excision load produces consequences such as power-frequency overvoltage.Therefore, the phase modifying equipment of lagging component must be installed, with the compensating charge capacity in system.Shunt reactor has the effect leading idle and restriction switching overvoltage in extra high voltage system that absorbs.And along with the continuous development of electric power system, more and more higher to the performance demands of reactor, wish that in many occasions the reactance value of reactor can realize regulating or control.
Realize that the continuously adjustable usual way of inductance has two kinds, namely change the gap and regulate magnetic bias.Changing the gap is to realize the adjustable continuously of inductance by the gas length that continuously changes in the magnetic circuit.This regulative mode requires to adopt accurate mechanical transmission mechanism, and its response speed is slow, and noise is big, and it is malfunctioning easily to produce mechanical action.Regulating magnetic bias is to realize the adjustable continuously of inductance by the DC excitation magnetic flux size that changes iron circuit.On this regulative mode governing speed far above the regulative mode that changes the gap, and there is not mechanical transmission mechanism, reliability is higher, but the raising along with the line voltage grade, this regulative mode not only exposes the high problem of power consumption, and owing to need tetanic stream excitation, the induction high-voltage problem that alternating current causes in the control winding in its work winding is difficult to solve, and has restricted its development.
At present, widely used in the controlled reactor is magnetic valve type controlled reactor unshakable in one's determination, but this equipment only has matured product at middle voltage level, is not used widely as yet in voltage levels.Its operation principle is equipment direct power taking in electrical network, feeds the control winding after the power electronic element rectification, and magnet valve unshakable in one's determination is carried out excitation, realizes that by the magnetic situation that changes magnet valve the induction reactance of upward work winding unshakable in one's determination is adjustable.Because the use of power electronic device is subjected to the restriction of voltage and capacity, this becomes this technology to the technical bottleneck of high pressure field development.
The technical scheme core that the present invention proposes is to have separated effectively alternate current operation winding and DC control winding.Work winding and control winding only exist in the mode of quadrature or oblique on magnetic circuit and partially overlap, this not only makes the induction reactance of the magnetic situation control work winding that the control winding can be by the intersection region, but also cut off effectively it with work between the winding magnetic coupling and be electrically connected.The magnetic control unit of equipment is in electronegative potential, neither bear line voltage, also side is through-flow not to produce induced voltage or induced current because exchanging, so the magnetic control unit is not subjected to the restriction of line voltage and transmission capacity, is convenient to design and produce out the controlled reactor equipment that is applicable to the high voltage field.
Summary of the invention
The purpose of this invention is to provide a kind of crossed-core type controlled reactor, allow the part main core also become a control part unshakable in one's determination, make its degree of saturation can be subjected to the control of direct current winding, thereby reach the purpose that exchanges the winding impedance on the control main core, simultaneously, exchange the winding magnetic flux can not with direct current winding interlinkage or interlinkage fully, thereby operating current can not cause reluctant induction high pressure in the direct current winding.And its total loss is less than general controlled reactor.
For achieving the above object, the present invention adopts following technical scheme:
A kind of crossed-core type controlled reactor includes a main core, is wound with the interchange winding on the main side column of main core, and a control is unshakable in one's determination, is wound with the direct current winding on the control iron core.Main core and control common sparing core limb unshakable in one's determination, make the degree of saturation that magnetic flux that the control winding produces can the control section main core, and exchange magnetic flux that winding produces not with control winding interlinkage or part is only arranged and control winding interlinkage, prevent that the magnetic flux that exchanges winding from producing very high induced voltage at the direct current winding.
Main core and control common sparing core limb unshakable in one's determination can be taked following three kinds of main modes:
Cut a breach at the part core limb of main core, in this breach, inserted described control part core limb unshakable in one's determination, the core limb that control is unshakable in one's determination and the orthogonal thereto or oblique of core limb of main core.
Cut a breach at the part core limb that control is unshakable in one's determination, in this breach, inserted the part core limb of described main core, the orthogonal thereto or oblique of core limb that the core limb of main core and control are unshakable in one's determination.
Main core is overlapping mutually with the part core limb of control iron core, the two orthogonal thereto or oblique.This control certain part unshakable in one's determination can with main core with peg graft, the tenon fourth of the twelve Earthly Branches or alternately mode such as dowel is overlapping mutually is one.
The direct current winding is lead or superconductivity wire coiling often.
Advantage of the present invention is:
1) electric current that exchanges in the winding can not allow the direct current winding produce induction, greatly reduces the insulating requirements of direct current winding;
2) reduction that requires owing to the direct current winding insulation also can be dwindled direct current winding volume and window size unshakable in one's determination, thereby reduce to control core volume;
3) since regulate the control core volume can be much smaller than the main core of work, exchange the winding impedance and only need to regulate control degree of saturation unshakable in one's determination and get final product and regulate, so the governing speed of this reactor can be higher than common magnetism-controlled reactor;
4) the interchange winding of this reactor and main core exist copper loss and iron loss, but its control direct current winding made from superconducting wire unshakable in one's determination does not have loss substantially, and its total loss is less than general controlled reactor.

Embodiment
Consult shown in Figure 1ly, crossed-core type controlled reactor main body of the present invention is unshakable in one's determination 2 by main core 1, control, exchange winding 3 and direct current winding 4 is formed.Wherein, exchange winding 3 on the main side column of main core 1; Direct current winding 4 is in control unshakable in one's determination 2.
Main innovate point of the present invention is: compare with the reactor of routine, increase in this reactor into a control unshakable in one's determination 2, increase into control unshakable in one's determination 2 and former main core 1 common sparing core limb.
Control unshakable in one's determination 2 can be one of following principal mode with the combining form of main core 1 common sparing core limb:
One: cut a breach at the part core limb of main core 1, in this breach, inserted described control part core limb unshakable in one's determination, the core limb that control is unshakable in one's determination and the orthogonal thereto or oblique of core limb of main core.As shown in Figure 1, embodiment for this combining form, earlier cut a breach at the secondary post of main core 1, the secondary post of the interior side column of control unshakable in one's determination 2 by this breach and main core is bonded with each other and is one, makes the direct current winding 4 that is wound with on these control iron core 2 outer side columns be mutually orthogonal with the winding 3 that exchanges on main core 1 main side column.The control part core limb that inserts opening unshakable in one's determination is called control section.
Its two: the part core limb in control unshakable in one's determination 2 has been cut a breach, inserts the part core limb of main core 1 in this breach, the core limb that control is unshakable in one's determination and the orthogonal thereto or oblique of core limb of main core.Fig. 2 shows a specific embodiment of this combining form.
Its three: make control unshakable in one's determination 2 overlapping mutually with the part core limb of former main core 1, the two orthogonal thereto or oblique, an embodiment of this combining form can be referring to shown in Figure 3.Overlap mode can have multiple, as peg graft, the tenon fourth of the twelve Earthly Branches or dowel etc. alternately.
Core limb shares more concrete form of juncture, as except exchanging post and direct current post, and main core and control common sparing core limb unshakable in one's determination; Or the interchange post of main core and the direct current post partial common of controlling iron core; Or the interchange post of main core and the control core limb partial common except the direct current post unshakable in one's determination; Or the unshakable in one's determination direct current post of control and the core limb of main core except exchanging post are shared etc.Enumerate no longer one by one herein, only need to guarantee that satisfying operating state gets final product, namely should satisfy: no matter which kind of form common sparing core limb described main core adopts with the control iron core, should make the degree of saturation of the flux regulator part main core that the direct current winding produces, and exchange magnetic flux that winding produces not with direct current winding interlinkage or part and direct current winding interlinkage are only arranged.
In the application, will exchange winding 2 in parallel accesses in the electrical network.When direct current winding 4 no currents, main core 1 is equivalent to the iron core of a closure, and it forms a reactor that band is unshakable in one's determination with exchanging winding 3, makes that exchanging winding 3 presents higher impedance.When direct current winding 4 excitations, can change control magnetized state unshakable in one's determination, and then the magnetic permeability of change control section and the magnetic flux of main core, finally changed the impedance that exchanges winding 3, particularly make control section abundant when saturated when direct current winding 4 excitations, main core 1 is similar to the iron core of an opening, at this moment, and reactor impedance minimum.
An advantage of this structure is that exchange flux and direct current flux are mutually orthogonal, therefore the electric current that exchanges in the winding can not allow the direct current winding produce induction, greatly reduce the insulating requirements of direct current winding, and because the reduction of insulating requirements, also can dwindle direct current winding volume and window size unshakable in one's determination, thereby reduce to control core volume.Can be unshakable in one's determination much smaller than working owing to regulating the control core volume, and the degree of saturation that adjusting exchanges the winding impedance only to be needed to regulate the control iron core gets final product, therefore the governing speed of this reactor can be higher than common magnetism-controlled reactor.At last, interchange winding and the main core of this reactor exist copper loss and iron loss, but its control direct current winding made from superconducting wire unshakable in one's determination does not have loss substantially, and its total loss is less than general controlled reactor.
Fig. 4 is that a model of crossed-core type controlled reactor of the present invention constitutes schematic diagram, and is unshakable in one's determination as main core with a volume, the 94 circle coils of coiling thereon, and open a gap.Unshakable in one's determination unshakable in one's determination as control with another volume, and the 72 circle windings of coiling thereon.The control main core breach that inserts unshakable in one's determination constitutes crossed-core type controlled reactor model.
Utilize voltage regulator, DC power supply to give respectively and exchange winding and the power supply of direct current winding, and monitoring exchanges terminal voltage and the electric current of winding, the performance that can test the reactor model.In experiment, the obstructed electric current of direct current winding, or by the 5A electric current, and exchange winding by 1～10A electric current is according to alternating current with exchanges the impedance of winding both end voltage calculating interchange winding.The model prototype experimental result is shown in the table among Fig. 5.
According to illustrating of Fig. 6, DC excitation has played regulating action to exchanging the winding impedance really.Prove that principle of the present invention is feasible.
The various embodiments described above can not depart from the scope of the present invention down in addition some variations, thus above explanation comprises and accompanying drawing shown in structure should be considered as exemplary, but not in order to limit the protection range of the application's patent.
