Description
Technical field
The utility model relates to a kind of controlled three phase combined 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 high pressure and EHV transmission; 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 lattice magnetised section unshakable in one's determination 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.
The utility model content
Goal of the invention of the present utility model: aim to 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 controlled three phase combined reactor that the utility model 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 main iron core 1 is a three column frame shape iron core completely, the main winding 3 of indirect current is being set on the square cylinder of this main iron core 1, described control iron core 2 is the shaped as frame iron core of a single hole opening, and the opening on frame body and main iron core 1 are inlayed and be combined into stacked-up type iron core main truss; Simultaneously on this control iron core 2 around the home control winding 4.
Described control iron core 2 is by a pair of, is respectively on the framework of junction of two main windings of main iron core 1.
Adopt technique scheme, the interior magnetic domain direction of iron core part that can change control iron core and the main iron core place of being cross-linked with each other by the size of regulating the direct current in the control winding changes the reactance value of reactor, 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
Below in conjunction with the drawings and specific embodiments the utility model is elaborated:
Fig. 1 is a structural representation of the present utility model.
Embodiment
A kind of controlled three phase combined 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 main iron core 1 is a three column frame shape iron core completely, the main winding 3 of indirect current is being set on the square cylinder of this main iron core, described control iron core 2 is the shaped as frame iron core of a single hole opening, and the opening on frame body and main iron core 1 are inlayed and be combined into stacked-up type iron core main truss; Simultaneously on this control iron core 2 around the home control winding 4.
Described control iron core 2 is by a pair of, is respectively on the framework of junction of two main windings of main iron core 1.
The operation principle of this controlled reactor is as follows:
The two ends of main winding 1 connect AC power, and main iron core 1 and main winding 3 are a reactor concerning alternating current, produce main flux at the alternating current that main winding 3 flows through in main iron core 1, and the main winding of main flux on three shaped as frame main iron cores 1 forms closed magnetic flux.And the two ends of two control windings 4 connect DC power supply, and direct current produces the control magnetic flux in control iron core 2.
Since the control magnetic flux that control iron core 2 produces be a kind of level around the control iron core to closed magnetic flux, the magnetic flux that is formed in square iron core by main iron core 1 and main winding 3 then is and the control magnetic flux is in the magnetic flux of orthogonal direction.Magnetic saturation degree in this two place iron core part depend on main flux and control magnetic flux the vector at this two place and.In working control,, make the magnetic domain direction of the place's of being cross-linked with each other iron core that change take place just because of by input control iron core is carried out autotelic controlling with control galvanic voltage of winding or electric current.Promptly by regulate direct currents size in the control winding 4 just can change this two place the magnetic saturation degree, thereby change the magnetic track rate of main iron core 1, reach the purpose of final continuous, smooth adjustment reactor reactance value.
