Compared with the traditional iron-silicon electric reactor, the iron-silicon electric reactor provided by the invention has the advantages of larger heat dissipation surface of the coil and better heat dissipation effect, the stability of the iron-silicon electric reactor in long-term use can be ensured, and the damage to the iron-silicon electric reactor is avoided.
Description
Technical field
The present invention relates to a kind of reactor, particularly a kind of iron core is the reactor of iron silica magnetic particle core.
Background technology
Reactor is also inductor, and reactance is divided into induction reactance and capacitive reactance, and relatively the classification of science is that impedor (inductor) and capacitive reactance device (capacitor) are referred to as reactor.Reactor has the effects such as filtering, rectification, protective circuit, and it is applied in electric power system as reactive power compensation means.At present, conventionally use reactor for silicon sheet core reactor, this reactor in use, can cause that the terminal voltage of reactor raises, and iron core and coil loss increase, and temperature raises, noise increases.In order to overcome above-mentioned shortcoming, on market, there is a kind of iron silicon reactor, its iron core is iron silica magnetic particle core, its loss is far below silicon sheet core, having low magnetostriction (low noise) performance, is energy storage material cheaply, and at high temperature performance is highly stable for iron silicon reactor.The structure of general iron silicon reactor as shown in Figure 1, comprise upper yoke 1, the lower yoke 2 parallel with upper yoke 1, iron core 3 and coil windings, iron core 3 is arranged between upper yoke 1 and lower yoke 2, coil windings is sleeved on iron core 3, coil windings comprises skeleton 4 and coil 5, coil 5 windings are on skeleton 4, the cross section of coil 5 is rectangle, the both sides of rectangular length direction parallel with the longitudinal center line of skeleton 4, if coil turn is more, the coil coiling that need to superpose, it is only rectangle length direction in outside on one side that such structure causes the radiating surface of coil, coil radiating effect is poor, long-time use, the temperature rise of coil, can cause the damage of iron sial reactor.
Summary of the invention
For the technical problem of above-mentioned existence, the object of the invention is: the iron silicon reactor that has proposed a kind of coil good heat dissipation.
Technical solution of the present invention is achieved in that a kind of iron silicon reactor, comprises upper yoke, lower yoke, iron core and the coil windings parallel with upper yoke; Described iron core is arranged between upper yoke and lower yoke; Described iron core is iron silica magnetic particle core; Described coil windings is sleeved on iron core; Described coil windings comprises skeleton and coil; Described coil winding is on skeleton; The cross section of described coil is rectangle; The both sides of described rectangular length direction and the longitudinal center line of skeleton are perpendicular; The equidistant winding of described coil is on skeleton.
Preferably, the described coil winding number of turn is 12.
Due to the utilization of technique scheme, the present invention compared with prior art has following advantages:
Iron silicon reactor of the present invention, the radiating surface of coil is larger than the radiating surface of the coil of iron silicon reactor in the past, and radiating effect is better, can ensure the stability of iron silicon reactor in long-time use, avoids the damage of iron silicon reactor.
Brief description of the drawings
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
The structural representation of the iron silicon reactor that accompanying drawing 1 is prior art;
Accompanying drawing 2 is the structural representation of iron silicon reactor of the present invention;
Wherein: 1, upper yoke; 2, lower yoke; 3, iron core, 4, skeleton; 5, coil.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described.
Of the present invention a kind of iron silicon reactor as shown in Figure 2, comprises upper yoke 1, lower yoke 2, iron core 3 and the coil windings parallel with upper yoke; Described iron core 3 is arranged between upper yoke 1 and lower yoke 2; Described iron core 3 is iron silica magnetic particle core; Described coil windings is sleeved on iron core 3; Described coil windings comprises skeleton 4 and coil 5; Described coil 5 windings are on skeleton 4; The cross section of described coil 5 is rectangle; The longitudinal center line of the both sides of described rectangular length direction and skeleton 4 is perpendicular; The equidistant winding of described coil 5 is on skeleton.
Iron silicon reactor of the present invention, the coil 5 being rectangle for cross section, because the both sides of the rectangular length direction in cross section and the longitudinal center line of skeleton 4 of coil 5 are perpendicular, and coil 5 is that equidistant winding is on skeleton, the radiating surface that makes coil is the both sides of rectangle length direction and one side of rectangle Width, the radiating surface of coil is larger than the radiating surface of the coil of iron silicon reactor in the past, radiating effect is better, especially under air-cooled condition, and under the natural state of cooling, the temperature rise of the coil 15～20K that also can on average decline, can ensure the stability of iron silicon reactor in long-time use, avoid the damage of iron silicon reactor.
Iron silicon reactor of the present invention, the described coil winding number of turn is 12 o'clock, result of use the best.When the coil winding number of turn is 12, coil in the past need to superpose and wind the line is 2 layers, and area of dissipation is little, and coil temperature rise is high, and present coil does not need stack coiling, and radiating surface is larger, and radiating effect is better, and iron silicon reactor result of use is also best.
Above-described embodiment is only explanation technical conceive of the present invention and feature; its object is to allow person skilled in the art can understand content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
