Abstract
The invention relates to an adjustable electric reactor used for controlling electric energy quality. An electric reactor iron core is formed by clamping one I-shaped iron core between two E-shaped iron cores with opposite openings, wherein an adjusting winding and a reactance winding are wound on middle iron columns of the two E-shaped iron cores respectively; a pair of permanent magnets with opposite magnetizing directions are embedded on the I-shaped iron core; and the two permanent magnets are located between the two pairs of opposite openings of the E-shaped iron cores respectively. By changing current in the adjusting winding, the magnetic conductivity of the iron cores is changed, so that the reactance value is changed. The adjustable electric reactor is simple in structure, low in construction cost and convenience for utilization and can be used for controlling the electric energy quality.
Description
Technical field
The present invention relates to a kind of reactor, is a kind of Regulatable reactor that can be used for utility power quality control specifically.
Background technology
Along with the increase of net capacity and the raising to grid supply quality requirement, Regulatable reactor is applied more and more extensive in electric power system: the capacitive reactive power absorbing electrical network as reactive power compensator, ensures power grid operation; Be applied in filtering mains by harmonics in electric-power filter, ensure power supply quality; To there is provided in inductive current as arc suppression coil and capacitance current in single phase ground fault, arc light is extinguished rapidly, and circuit recovers normal; Realize heavy-duty motor as soft-starting device for motor smoothly to start, avoid great start-up current cause greater impact to electrical network and cause line voltage current fluctuation.
Existing Regulatable reactor is of a great variety, and wherein magnet controlled reactor uses quite wide, and its principle is that the size by changing additional excitation changes the magnetic resistance size realization of iron core, has the advantages such as reliability is high, compensation capacity large, reactance value continuously adjustabe.In current magnet controlled reactor, a class relies on external dc power supply to realize the saturated magnetic bias of core of reactor, and as Split Core Type Controllable Reactor, this kind of reactor is complicated, and producting process difficulty is large.Also have a class to be changed the saturation of core of reactor by the DC control current that self thyristor rectifier produces, as magnetic valve type controllable reactor, although use thyristor reaction speed fast, technology is more ripe, and cost is high, difficult in maintenance.
Summary of the invention
The present invention, in order to solve the problem, provides a kind of Regulatable reactor that can be used for utility power quality control, and regulate the electric current in winding regulate the saturation of core of reactor thus regulate reactance value by changing, structure is simple, and cost is low, easy to use.
The technological means that the present invention takes is: a kind of Regulatable reactor that can be used for utility power quality control, core of reactor is relative by two E shaped iron core openings, therebetween I shaped iron core composition, the middle iron prop of two E shaped iron cores is full of respectively and regulates winding and reactance winding, I shaped iron core is embedded with the permanent magnet that a pair magnetizing direction is contrary, two permanent magnets lay respectively at E shaped iron core two between relative opening, and the magnetizing direction of described permanent magnet is parallel to the axis of I shaped iron core.
The invention has the beneficial effects as follows: use conventional E, I shaped iron core, structure is simple, Simplified flowsheet, and be easy to produce, cost is low.Produce by regulating winding the magnetic flux size that the magnetic flux contrary with permanent magnet flow direction changes reactor, thus change the magnetic resistance size of iron core, reach the object regulating reactance value, and can regulate continuously, it is convenient to control, and improves power system power supply quality.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention.
Embodiment
Two E shaped iron core 1 openings are relative, and therebetween I shaped iron core 2 forms the iron core of reactor.The middle iron prop of an E shaped iron core is full of and regulates winding 3, the middle iron prop of another E shaped iron core is full of reactance winding 4.I shaped iron core 2 is embedded with two permanent magnets 5, lay respectively at E shaped iron core two between relative opening, the magnetizing direction of these two permanent magnets 5 is parallel to the axis of I shaped iron core and direction is contrary.As shown in Figure 1, the magnetizing direction of two permanent magnets 5 in opposite directions.Two permanent magnets 5 set up static, equally distributed permanent magnetic field in the core which, and now core interior magnetic field is saturated, and magnetic permeability is low, and the reactance value of reactor is less.Establish after adjustment winding 3 passes into the electric current in direction as shown in Figure 1 and regulate magnetic field, in the E shaped iron core being wound with reactance winding, permanent magnetic field is contrary with adjustment magnetic direction, and cause the magnetic flux density of the E shaped iron core being wound with reactance winding to reduce, reactance value increases.The magnetizing direction of two permanent magnets 5 also can dorsad, and now regulating winding 3 to pass into sense of current should be contrary with shown in Fig. 1.The size of reactance value regulates the size of the electric current of winding to be directly proportional to input, can regulate reactance value by regulating the size of input current.
Gizmo can be applicable in utility power quality control, when such as compensating as three-phase imbalance, three Regulatable reactor are one group, respectively by the three-phase of reactance winding access electrical network, alternating current containing certain amount of bias is passed into regulating winding according to the threephase load situation measured, thus regulate the reactance value of reactor to adjust threephase load, make it balance, improve the quality of power supply.
