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, specifically a kind of REgulatable reactor that can be used for utility power quality control.
Background technology
The raising required with the increase of net capacity and to grid supply quality, REgulatable reactor is in power system
Using more and more extensive：The capacitive reactive power of electrical network is absorbed as reactive power compensator, it is ensured that power grid operation；Apply in electric power
Mains by harmonics is filtered in wave filter, it is ensured that power supply quality；There is provided inductive current to neutralize singlephase earth fault as arc suppression coil
In capacitance current, arc light is extinguished rapidly, circuit recovers normal；Realize that heavy-duty motor is smoothed as soft-starting device for motor
Start, it is to avoid great start-up current causes greater impact to electrical network and causes line voltage current fluctuation.
Existing REgulatable reactor species is various, and wherein with quite extensively, its principle is by changing additional encouraging to magnet controlled reactor
The size of magnetic is realized the magnetic resistance size that changes iron core, excellent with high, big, the reactance value continuously adjustabe of compensation capacity of reliability etc.
Point.At present a class realizes the saturation magnetic bias of core of reactor by external dc power supply in magnet controlled reactor, and such as iron core split type is controllable
Reactor, this kind of reactor is complicated, and producting process difficulty is big.The direct current that also a class is produced by itself thyristor rectifier
Control electric current changing the saturation of core of reactor, such as magnetic valve type controllable reactor, although fast using IGCT response speed,
Technology is more ripe, but cost is high, difficult in maintenance.
The content of the invention
The present invention is in order to solve the above problems, there is provided a kind of REgulatable reactor that can be used for utility power quality control, by changing
Become and adjust the electric current in winding to adjust the saturation of core of reactor so as to adjust reactance value, simple structure, low cost is used
It is convenient.
The technological means that the present invention takes are：A kind of REgulatable reactor that can be used for utility power quality control, core of reactor
Relative by two E shaped iron cores openings, folder one I shaped iron cores composition in centre is full of respectively tune on the middle iron prop of two E shaped iron cores
Section winding and reactance winding, are embedded with a pair of contrary permanent magnets of magnetizing direction on I shaped iron cores, two permanent magnets are located at respectively E types
Between the opening of iron core two pairs of opposed, the axial direction of the magnetizing direction of the permanent magnet parallel to I shaped iron cores.
The invention has the beneficial effects as follows：Using conventional E, I shaped iron core, simple structure, Simplified flowsheet, it is easy to produce, make
Valency is low.Change the magnetic flux size of reactor by adjusting winding generation with permanent magnet magnetic flux magnetic flux in opposite direction, so as to change
Become the magnetic resistance size of iron core, reach and adjust the purpose of reactance value, and can continuously adjust, it is easy to control, improve power system and supply
Electricity quality.
Description of the drawings
Fig. 1 is the structure chart of the present invention.
Specific embodiment
Two E shaped iron cores 1 are open relatively, and centre one I shaped iron core 2 of folder constitutes the iron core of reactor.One E shaped iron core
Regulation winding 3 is full of on middle iron prop, on the middle iron prop of another E shaped iron core reactance winding 4 is full of.It is embedded with I shaped iron cores 2
Two permanent magnets 5, respectively between the opening of E shaped iron core two pairs of opposed, the magnetizing direction of the two permanent magnets 5 is parallel to I
Shaped iron core it is axial and in opposite direction.As shown in figure 1, the magnetizing direction of two permanent magnets 5 is opposite.Two permanent magnets 5 are in iron core
Middle foundation is static, equally distributed permanent magnetic field, now core interior magnetic field saturation, and pcrmeability is low, the reactance value of reactor
It is less.Regulation magnetic field is established after winding 3 is passed through the electric current in direction as shown in Figure 1 when adjusting, the E sections of reactance winding is being wound with
In core, permanent magnetic field and regulation magnetic direction are conversely, cause to be wound with the magnetic flux density reduction of the E shaped iron cores of reactance winding, reactance
Value increase.The magnetizing direction of two permanent magnets 5 also can dorsad, now adjust winding 3 be passed through sense of current should be with phase shown in Fig. 1
Instead.The size of electric current that the size of reactance value adjusts winding to input is directly proportional, can by adjust the size of input current come
Adjust reactance value.
Gizmo can be applicable in utility power quality control, when compensating for example as three-phase imbalance, three REgulatable reactors
For one group, during reactance winding to be accessed respectively the three-phase of electrical network, it is passed through to regulation winding according to the threephase load situation of measurement and is contained
There is the alternating current of certain amount of bias, adjust threephase load so as to adjust the reactance value of reactor so as to balance, improve electric energy
Quality.
