Abstract
The basic structure of reactor is a iron core with the shape like the Chinese character 'ri'. A control iron core with the shape like the Chinese character 'kou' is formed by connecting iron cores to two ends of central post of iron core with the shape like the Chinese character 'kou'. Control windings are wrapped on two sides of the control iron core; and operating windings are wrapped on two pieces of side post of iron core with the shape like the Chinese character 'ri' in main magnetic circuit. Control magnetic circuit carries out local adjustment of magnetic saturation for the main magnetic circuit so as to change magnetic resistance of main magnetic circuit. The method does not generate harmonic when controlling magnitude of current in main circuit. Advantages are: simple structure, low cost, good performance and easy of use.
Description
Technical field
What the present invention relates to is Regulatable reactor.Particularly the electricity that uses of Electricity Departments is transferred iron core reactor.
Background technology
Electricity transfers iron core reactor to be mainly used in the static passive compensation device, as the use in parallel of adjustable inductive element with capacitor bank, by adjusting inductance value, capacity current unnecessary in the networking is compensated, or connect to use to limit with the capacitor group and shove and harmonic wave.It all is a kind of saturable reactors that existing electricity is transferred iron core reactor, it is operated in the magnetic saturation state, promptly magnetic flux density get very high, the shortcoming that this Regulatable reactor exists is, because it is operated in the magnetic saturation state, along with the change of electric current is big, wave distortion also becomes greatly, so produce a large amount of harmonic waves is arranged, this brings a lot of troubles to use, therefore, must dispose filter in the device during use, cost is very high.
Summary of the invention
The purpose of this invention is to provide a kind of simple in structure, low cost of manufacture,, performance is good, no harmonic wave produces, electricity easy to use is transferred iron core reactor.
Technical scheme of the present invention is by day font iron core, and the both end sides of newel of font iron core connects iron core and forms square shape control iron core in day, is wound with the control winding in square shape control iron core both sides, is wound with the work winding and constitutes on the two side columns of day font iron core; Or by two days font iron core, both end sides at the newel of font iron core on the two is connected with iron core, the newel of itself and font iron core on the two is combined to form square shape control iron core, on the newel of font iron core on the two, be wound with the control winding, on the two side columns of font iron core on the two, be wound with the work winding and constitute.Both technical patterns one to, compare the former and adopt a day its planform of font iron core to be the T font, the latter adopts two days its structure of font iron core to be H shape.
When in the magnetic circuit air-gap being arranged, air-gap influences the magnetic resistance size in the magnetic circuit, and magnetic resistance change rate influences the size of magnetic flux, and magnetic flux change influences the inductance value of coil on the magnetic circuit, so can change the inductance value of coil with the length of regulating the space.Magnetic resistance is very big when the iron core magnetic saturation, is equivalent to add air-gap, if the magnetic saturation degree in the magnetic circuit changes, magnetic resistance also changes thereupon, causes the variation of magnetic flux, so the inductance value of coil changes in the magnetic circuit.
The present invention is when regulating the DC control electric current that changes control coil, main magnetic circuit day, the word iron core changed with the magnetic saturation degree of the local iron core of control magnetic circuit iron core intersection (referring to the A ' shown in the accompanying drawing, A " district); so the magnetic resistance of main magnetic circuit, magnetic flux change, thus regulate the inductance value of actuating coil on the main magnetic circuit.
The magnetic flux density that the present invention produces actuating coil, the linearity range work that design is in the magnetization curve of iron core gets final product.
The present invention controls magnetic circuit main magnetic circuit is just carried out local magnetic saturation adjustment, is equivalent to add adjustable air-gap at main magnetic circuit, changes the magnetic resistance of whole main magnetic circuit, when this way is controlled the size of current of main circuit, does not produce harmonic wave.It is simple in structure, low cost of manufacture, and performance is good, and is easy to use.
