Non-conductor contact power transfer

Technical field

The present invention relates to a kind of power transfer, especially a kind of non-conductor contact power transfer.

Background technology

At present, for the application that needs electric energy transmitting, two kinds of schemes are arranged at present, first kind what extensively obtain practical application is transformer elementary, secondary integral type, and perhaps transformation is used, and perhaps isolates and uses, this mode is when changing load, easily the origination point spark does not meet the requirement of safety production rules, the serious harm safety in production.Second kind is transformer for noncontact charging and charged electric implement device, i.e. the separate type transformer.Its manufacturing and research are at present mainly in theoretical and a few experiments conceptual phase.The non-contact electric energy transmission technology way adopts be primary and secondary separate by electromagnetic induction energy-delivering transformer that is coupled, the non-contact electric energy transmission technology can satisfy to a certain extent at chemical industry, drilling well, industrial and mineral, the use of the electrical equipment feed restriction under some occasion in the special industries such as undersea detection, but leakage field is big, the cost height, efficient is low, " Guangming Daily " network edition 02 month 08 07:39 time in 2007 is reported news " the non-contact electric energy transmission technology obtains breakthrough ", applied for the development device of three patents of invention in it is reported, its electric energy output efficiency of transmission is 70%, under the not high environment of some power consumption efficiencies such as household electricity, still can meet the demands, but this electric energy transmitting efficient is obviously on the low side under the high condition of a lot of power consumption efficiencies, and manufacturing cost is too high.Therefore, designing the non-conductor contact power transfer that a kind of leakage field is little, cost is low, efficient is high, is the present technical issues that need to address.

Summary of the invention

Technical problem to be solved by this invention provides the non-conductor contact power transfer that a kind of leakage field is little, cost is low, efficient is high.

The technical scheme that the present invention solves its technical problem is:

Non-conductor contact power transfer, comprise feeder ear and electricity consumption end, feeder ear comprises " ［ " type or " E " font feeder ear magnetic core and be wrapped in the primary coil on the feeder ear magnetic core and be connected the AC power at primary coil two ends, the electricity consumption end comprises " ］ " type or anti-" E " font electricity consumption end magnetic core and be wrapped in the secondary coil on the electricity consumption end magnetic core and be connected the load at secondary coil two ends, feeder ear is with after the electricity consumption end combines, feeder ear magnetic core and electricity consumption end magnetic core constitute approximate complete " mouth " font or " day " font magnetic core, and feeder ear magnetic core and electricity consumption end magnetic core constitute closed magnetic line of force passage.

Preferably, the gap convergence between feeder ear and the electricity consumption end zero.

Further preferably, feeder ear also comprises feeder ear magnetic core carrier, the right side of feeder ear magnetic core carrier is provided with left conductor contact point, on left conductor contact point, be connected with the feeder ear holding wire, the electricity consumption end also comprises electricity consumption end magnetic core carrier, the left side of electricity consumption end magnetic core carrier is provided with right conductor contact point, is connected with electricity consumption end signal line on right conductor contact point, and left conductor contact point contacts electrical connection with right conductor contact point.

Again further preferably, described left conductor contact point is two, the feeder ear holding wire is two, be connected on two left conductor contact points, described right conductor contact point is two, and electricity consumption end signal line is two, is connected on two right conductor contact points, two feeder ear holding wires are as the power line of feeder ear control device, and two electricity consumption end signal lines are as the power line of electricity consumption end control device.

Because the present invention adopts feeder ear that transformer and magnetic core and control circuit are installed, the electricity consumption end is installed transformer secondary output coil, magnetic core and load and control circuit, install feeder ear and electricity consumption end device zero clearance, so just can both reach the efficient of integrated transformer, reach the security performance of wireless power transmission again.The control signal transmission contacts transmission with information signal transmission use conductor, and signal code is controlled in 1 milliampere, reaches the requirement of the intrinsic safety in the safety regulations.The control circuit of installing at feeder ear and electricity consumption end is used for finishing the control of the break-make and the watt level of power supply.
