Description
Technical field
The present invention relates to wireless energy transfer field, particularly relate to wireless energy transform device and the method thereof of a kind of high voltage transmission line non-contact power.
Background technology
Along with the continuous speed-raising of transportation by railroad in recent years and the fast development of bullet train, the safety requirements for railway and train operation improves thereupon. Therefore, the parameter safety detection in each portion of train operation being seemed very important, such as all kinds of parameters of railroad track, comprising: rail temperature, stress, sedimentation, distortion etc., to accurately judging rail state, control train running speed all has great significance; The and for example on-line checkingi of train transmitting line, the transmitting line of big current, high-voltage is once occur power-off accident to cause great harm by the security of the lives and property of people. In this context, the on-line monitoring technique of transmission line is widely used, and its monitoring range comprises contact and cable splice survey temperature, wire icing state, the insulator contamination etc. of high-voltage switch gear. And it is subject to the restriction of the on-the-spot geographical environment of transmitting line, insulation safety and electrical isolation requirement etc., the power supply of the online detection instrument of high ferro transmission line directly can not be supplied by low pressure end, the distance of monitoring equipment distance supply station is too far away again simultaneously, provides the scheme of power supply also unrealistic from supply station lead-in wire. Therefore, the supply of high-quality power supply becomes the important factor that restriction transmission line online monitoring system improves development, is badly in need of a kind of function mode and the measure that can ensure power supply chronicity and power stability.
Compare conventional transmitting line monitoring equipment power supply mode at present to have: solar panel is powered, laser powered sensor and bussed supply etc.
1. solar panel is powered: when there being solar irradiation, and solar panel is powered for on-line monitoring equipment, and store battery is charged by another part, so as subsequent use when cloudy day or rainy day. There is following drawback in this kind of method: 1. output rating is subject to the restriction of solar panels area, and area is greatly not easily installed. 2., when sleet sky, south is more, the utilization ratio of solar cell is not high.
2. laser powered sensor: luminous by high-power laser generator in cell site, and adopt optical fiber that luminous energy is transferred to receiving end, carry out Conversion of energy (light energy conversion is electric energy) by the photocell of receiving end, for monitoring equipment is powered. But this kind of method is applicable to smooth wide level land, and just meaningless mountain region in great numbers for forest and just uneven.
3. bussed supply: most research about bussed supply at present is current transformer and gets energy.Due to logical on transmission line be the alternating-current of big current, so space can produce the magnetic field of alternation around. By adding that magnetic conductance body fixes magnetic circuit at transmission line overcoat, and the principle according to electromagnetic induction obtains energy, and this is also the method for supplying power to of a kind of new proposition.
But this kind is got and mode can also be there is drawback: 1. install inconvenient, it is necessary to magnetic core on cover around high pressure bus, the fixing difficulty of magnetic core and cost height; 2. power line current fluctuation is big, when electric current hour, energy harvesting can be caused inadequate, exists " getting energy dead band "; When current is excessive, spike pulse electric current can be caused the damage of components and parts.
Meanwhile, current research is the improvement in the structure, material of mutual inductor mostly, so that transmission efficiency improves. But the output energy of these researchs is very low at present, far can not meet the power grade needed for monitoring equipment.
For above problem, propose herein based on a kind of scheme that monitoring equipment is directly powered by wireless power transmission, utilization transmission of electricity bus.

2. magneticinduction manifold type, utilizes faraday electromagnetic induction principle, to realization of goal wireless power transmission closely. Namely, when there being two coils to be positioned over relative close position, the exchange current in a coil, by the coupling of alternating magnetic field, can produce inductive emf in another coil, thus realize the transmission of wireless electric energy. This kind of technology is applied more in a portable device, such as mobile phone charging etc.
3. magnet coupled resonant type, when the resonant frequency of two objects is identical, can realize the transmission over radio of electric energy by magnetic coupling mode between it, simultaneously that the impact of other disresonance objects of surrounding is very little again, thus can realize transmitting more at a distance.
