Description
Technical field
Be a kind of non-contact electric power (non-contact power supply), refer to non-contact electric power and the coupling detection method thereof of a kind of tool built-in coupling detection device (built-in coupling detection device) especially.
Background technology
Because general known contact power supply needs to make the electric energy transmitting of contact type by plug and socket, so its inborn defective is arranged.For example, described contact power supply can produce contact sparking (when particularly power is big) when using, and the danger of electric shock is arranged; And its metal contact is also easily former thereby cause efficiency of transmission to descend because of wearing and tearing, oxidation or dust covering etc., or because of loose contact, and the life-span of lowering electric supply installation; In addition, described known contact power supply also has the inconvenience that needs to insert contact.These problems are to the application scenario of many power consumption equipments and demand and inapplicable, such as in the mine, petroleum drilling and mining, water and mobile device or the like.On the contrary, the non-contact electric power of reaching the electric energy transmitting demand by the electromagnetic coupled mode can be avoided these problems; This mode need not any mechanical. points connection, except above-mentioned occasion is suitable for, also be applicable to the environment of dust free room and hospital, can also save the inconvenience of plug-in.At present known non-contact electric power uses in a large number at electric razor, electric toothbrush, towards tooth on mechanical, electrical motor-car, storage transportation and the equipment such as gantry crane that convey goods.
In addition, non-contact electric power also often uses in the power supply of packaged type device, first and second side (primary side and secondary side) of utilizing detachable transformer (detachable transformer) is as coupling interface, when transformer first and second side mutually near (meaning is that supply unit and packaged type device are approaching mutually) when locating, i.e. supply power.Because when the distance between transformer first and second side was excessive, electric energy transmitting efficient can decline to a great extent, so after transformer first and second side approaches to fixed range, just supplied enough power supplys to the packaged type device.Thus, before the packaged type device no show still location, power end needn't be powered, and is the mode that can save electric power, becomes the essential problem that solves but predict whether to locate just to finish.

And general common known non-contact electric power 1 predict whether its transformer first and second side 111 and 112 has arrived the location or the method that has been coupled comprise install sensitive switch additional, use infrared ray or laser detecting device, also or use wireless communication apparatus transmission information learn whether to locate/be coupled and finish.That is, the predicting localization method and all need be dependent on arrangement for detecting or the communication device that adds of described known non-contact electric power 1, thereby make its manufacturing cost higher relatively, and complicated because of the structure of system, the reliability of its system is also relatively low.
And in the disclosed in the present invention non-contact electric power, then and needn't install any other detecting or communication device additional, so need not bear the extra detecting or the cost of communication device, only need revise the built-in contents of program of controller of this non-contact electric power, and utilize the intrinsic current sensor that is arranged on this transformer primary side, the size of one electric current of this transformer primary side of flowing through of foundation detecting gained, whether this transformer primary side and this Circuit Fault on Secondary Transformer that are this detachable transformer of decidable have reached the location, and then the power consumption can save standby time the and reduce electromagnetic interference noise.
When the disclosed non-contact electric power of the present invention, predict by this electric current of this transformer primary side of flowing through this primary side of this detachable transformer and this secondary side whether locate finish after, its power end can switch to one from a sense mode and send power mode, so not only can save and not send unnecessary power consumption before the electricity as yet, and the electromagnetic interference noise can reduce standby the time.Whether the present invention utilizes the power end operating frequency under high frequency situations, and the transformer primary side current is less, and the characteristic that changes with air gap, can predict the primary side of this detachable transformer and this secondary side by power end and locate/be coupled and finish.
Duty is event, and the inventor is an idea of thinking and improve invention in view of the shortcoming of known technology, can invent out " non-contact electric power of tool built-in coupling detection device and coupling detection method thereof " of the present invention eventually.
