Abstract
The controllable composite type reactor includes following parts: main iron core; AC main winding wound on the main iron core; control iron core; DC control winding wound on the control iron core. Characters are that control iron core is a hollow cylindrical iron core body, and framework type main iron core with opening is embedded on up and down planes of the cylindrical iron core body so as to constitute main skeleton of star shaped iron core; the control iron core includes control winding wound on inside and outside the cylindrical body; main winding is wound on core body of main iron core paralleled to cylindrical body of cylindrical control iron core in radial. Changing magnitude of current of the control winding, the reactor can change magnetic permeability of cylindrical iron core in axial direction. Thus, the reactor changes reactance value of AC reactor so as to reach purpose of adjusting reactor continuously and smoothly.
Description
Technical field
The present invention relates to a kind of Contrable combination type reactor, is a kind of Wound-rotor type reactance induction installation with inductance effect.
Background technology
Controlled reactor is the important device of carrying out voltage control and reactive power compensation in the electric power system, is widely used in power transmission and distribution; Line voltage, reactive power flow control; Improve the stability of a system and increase through-put power; Supergrid power frequency and switching overvoltage restriction; System earth current compensation (arc suppression coil); Aspects such as the harmonic wave inhibition of power rectifier system.
Controlled reactor requires to have suitable voltage, range of capacity broadness, and continuous parameters, level and smooth, Fast Adjustable, reliability height, harmonic wave are little, small accommodation area, safeguards characteristics such as simple.And the controlled reactor technology does not also reach above requirement at present.All be by adopting switch to switch the change that the constant reactance device is realized reactance value in the electric power system of traditional high-power.From the seventies in last century, the method and apparatus of many quick adjustment reactance has appearred both at home and abroad.
Mainly following several by having:
1, its principle of direct current saturable is that a lattice iron core magnetised section is set in the alternate current operation winding, by changing the size of direct current magnetic assist magnetic flux, reaches and regulates the equivalent magnetic conductance that exchanges.Its defective is that volume is big, harmonic wave big, loss is also big.
2, the magnetic valve type method of utilizing the self coupling DC excitation to control the degree of saturation of iron core realizes the continuous adjusting to offset current.Its defective is that volume is big, and harmonic wave is also especially big, and noise is also big.
3, SCR control method, this is domestic a kind of method of comparatively generally using in a long time, mainly change the equivalent inductance of reactor, thereby reach the purpose of continuous adjusting offset current by changing with the be in parallel ON time of thyristor of the adjustable winding of constant reactance device part; Its defective is that harmonic wave is big especially, and noise is big, often need be used by special filter.
Therefore, how to overcome the deficiency of existing all kinds of reactors, for the user provides a kind of simple in structure, loss is little, harmonic wave is little, control good linearity, reactor that modification scope is big have become this product design, production unit a kind of expectation.
Summary of the invention
The object of the invention provide a kind of simple in structure, loss is little, harmonic wave is little, control good linearity, modification scope is big, overhauls easily controlled reactor to overcome the deficiency that prior art exists.
In order to reach the foregoing invention purpose, a kind of Contrable combination type reactor that the present invention proposes, comprise main iron core 1, the main winding 3 of indirect current on the main iron core 1, control iron core 2, on control iron core 2, lead to galvanic control winding 4, it is characterized in that: described control iron core 2 is the tubular iron-core workpiece of a hollow, at least inlay the shaped as frame main iron core of a band opening on the upper and lower plane of this tubular iron-core workpiece, forming " star " iron core main truss thus; Described control iron core 2 is provided with the control winding 4 inside and outside cylindrical shell around the home; 3 of described main windings around the home with main iron core core body that control iron core cylindrical body radially parallels on.
Adopt technique scheme, can change the reactance value that the magnetic domain direction of controlling in the iron core changes reactor by the size of regulating the direct current in the control winding, have simple in structure, loss is little, voltage, capacity are continuous, level and smooth adjustable extent is wide, and no harmonic linear is good, overhauls advantage easily.
Description of drawings
The present invention is described in detail below in conjunction with the drawings and specific embodiments:
Fig. 1 is a structural representation of the present invention.
Embodiment
This Contrable combination type reactor as shown in the figure, comprise main iron core 1, the main winding 3 of indirect current on the main iron core 1, control iron core 2, on control iron core 2, lead to galvanic control winding 4, it is characterized in that: described control iron core 2 is the tubular iron-core workpiece of a hollow, is inlaying the shaped as frame main iron core 1 of a band opening on the upper and lower plane of this tubular iron-core workpiece at least.
Shaped as frame main iron core and " star " iron core main truss that the tubular iron-core workpiece is formed that this accompanying drawing provides by three band openings; Described control iron core 2 is provided with the control winding 4 inside and outside cylindrical shell around the home; 3 of described main windings around the home with main iron core core body that control iron core cylindrical body radially parallels on.
The operation principle of this Contrable combination type reactor is as follows:
The two ends of main winding 3 connect AC power, and main iron core 1 and main winding 3 are a reactor concerning alternating current, and the electric current by main winding 3 produces the closed main flux that exchanges at main iron core 1 and tubular iron core 2.The two ends of control winding 4 connect DC power supply, and direct current produces the closure control magnetic flux along tubular iron core circumferencial direction in cylindrical body control iron core 2; By changing the size of current of control winding 4, can change the magnetic permeability of tubular iron core axial direction, thereby change the reactance value of AC reactor, reach purpose continuous, the smooth adjustment reactor.
