Abstract
The invention discloses a magnetic circuit power transmission system, comprising a primary electromagnetic induction component, a secondary electromagnetic induction component and a transmission wire; each electromagnetic induction component comprises a semicircular magnetic core and a coil that surrounds on the semicircular magnetic core; and two ends of the transmission wire are connected with the two semicircular magnetic cores respectively so as to form a magnetic circuit. When the primary coil is electrified, a magnetic current is generated on the semicircular magnetic core surrounded by the coil; furthermore, a magnetic circuit is formed by a magnetic leading wire so that the secondary coil generates an induction current, thus realizing the power transmission without current in single wire. As the transmission wire contains magnetic current (constant magnetic flux) only, the magnetic energy is not consumed and the consumption of the electric power is also avoided. Furthermore, the system does not relate to high voltage and can arrange the transmission wire under the ground, thus effectively avoiding the effect of weather.

Embodiment
Further specify technical scheme of the present invention below in conjunction with drawings and Examples.
At first, the design philosophy and the principle of magnetic circuit power transmission system of the present invention are made brief description.
The Pan Xingyuan professor of Shanghai Communications University is in " electrotechnical, electronic teaching material " (publishing house of Shanghai Communications University publishes in September, 2005) of its chief editor, the magnetic circuit of transformer, the relativity of circuit are pointed out that " though magnetic circuit and circuit have contrast relationship, both physical essence are different.During as open circuit, there is electromotive force to exist but no current, and in magnetic circuit, has air-gap, as long as but have magnetomotive force that magnetic flux then must be arranged; In circuit, direct current is wanted consumed energy during by resistance, and in magnetic circuit, constant flux consumed energy not during by magnetic resistance, and in magnetic circuit, constant flux consumed energy not during by magnetic resistance." just according to permanent magnetic flux this theory of consumed energy not when the magnetic resistance; and existing core type transformer is out of shape parsing; carry out the design philosophy that electric power is carried thereby produced employing magnetic circuit of the present invention: see also shown in Figure 1; existing core type transformer 10 comprises magnetic core 11 and primary and secondary coil 12,13; primary and secondary coil 12,13 is respectively around the home at the two ends of magnetic core 11, and cuts off magnetic mutually.This magnetic core 11 of hypothesis has very strong plasticity now, and both sides mutually insulated and magnetic up and down extremely, putting before this, magnetic core 11 is drawn back mutually round about, make it extend into wire as much as possible in both sides up and down, and be bundled together by the both sides up and down that exhausted magnetic integument extends two magnetic cores and become a single line, be used for substituting traditional power main.
According to above-mentioned principle, conveying system 20 of the present invention specifically be achieved in that see also shown in Figure 2, this conveying system 20 comprises primary and secondary electromagnetic induction part 21,22 and pipeline 23, and each electromagnetic induction part 21,22 includes semi-circular magnetic core 24 and the coil 25 on semi-circular magnetic core 24 around the home; Pipeline 23 two ends are connected with two halves toroidal core 24 respectively, and form a magnetic loop.Please in conjunction with shown in Figure 3, above-mentioned pipeline 23 is single, comprise two magnetic wires 231 that also cut off magnetic mutually of being bundled together, two magnetic wires 231 are connected with two semi-circular magnetic cores 24 respectively, and form a magnetic loop (on section at the A-A of pipeline 23, the flow direction of two magnetic wires 231 is opposite, is respectively the N utmost point and the S utmost point).Need to prove that at this material of this magnetic wire 231 and semi-circular magnetic core 24 is electromagnet, as silicon steel material etc., certainly, the material of this magnetic wire 231 is a permanent magnet, and the material of semi-circular magnetic core 24 is an electromagnet.And be equipped with exhausted magnetic integument 26 at the outer wall of pipeline 23, semi-circular magnetic core 24 outer walls and inwall, also be equipped with exhausted magnetic integument at the outer wall of two magnetic wires 23 1.Like this, can make between semi-circular magnetic core 24 and the coil 25 and the exhausted magnetic of homogeneous phase between the magnetic wire 231, avoid taking place magnetic leakage.During work, primary and secondary electromagnetic induction part 21,22 is laid in electric power output ground and destination respectively, and pipeline 23 can be on being erected in the air, owing to do not relate to high pressure, also can be laid on underground, and be set to undergroundization good, thereby can avoid being subjected to the influence of natural calamities such as weather.When the coil 25 to elementary electromagnetic induction part 21 feeds constant alternating current, on the semi-circular magnetic core 24 of its correspondence, produce magnetic current, and form the magnetic loop of permanent magnetic flux by magnetic wire 231, make the coil 25 of secondary electromagnetic induction part 22 produce induced current output, thereby realize the currentless electric power conveying of single line.Owing to have only magnetic current (permanent magnetic flux) in pipeline 23, no magnetic energy loss is not even fed distance far has the loss of any electric energy more yet.Certainly, in real process, might be subjected to the influence of other various factors, even if produced plurality of magnetic loss and electrical loss, compare with the electric energy that whole electric power is carried, that also is quite few.
Conveying system 20 of the present invention adopts magnetic circuit to carry out electric power and carries, because no electric energy loss, therefore compared with prior art, can reduce by about 30% energy consumption, also just be equivalent to increase about 30% energy output, thereby improved the efficiency that electric power is carried greatly, for country brings huge economic benefit.
Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in claims scope of the present invention variation, the modification of the above embodiment.
