Description
Technical field
The present invention relates to the electric supply installation of a kind of collecting ring and use collecting ring.
Background technology
Usually load on when accepting the power supply power supply, need directly obtain electric energy by electric conductor.Between power supply and load, during no relative motion, just can solve with lead or plugs and sockets etc.When there was relative motion in the two, simple lead, plugs and sockets can't satisfy, and people have designed the collecting ring brushgear for this reason.Collecting ring and brush satisfied the relative motion of power supply and load in sliding contact place, satisfied electric current unimpeded in the entire circuit loop simultaneously.Because collecting ring exists sliding friction to contact with brush, so this has just brought inconvenience, at first, because therefore fretting wear between brush and the collecting ring needs periodic replacement; In addition, because contact is the sliding friction formula, cause the unstability of the operating current of power supply owing to the instability of contact resistance through regular meeting.
The technical scheme that the patent of invention " the non-contact power supply method and the device thereof of electrical equipment " that at present existing publication number is CN1674405 provides is: can change civil power or direct current is the electric energy change-over circuit of high-frequency alternating current mains side setting, the high frequency output winding in the output loop of electric energy change-over circuit is arranged on the high frequency magnetic core; In the electrical appliance side power-switching circuit is set, the high-frequency input coil in input loop of electric energy change-over circuit is arranged on another high frequency magnetic core; Make described two high frequency magnetic core amalgamations, the high-frequency electrical energy that the mains side power-switching circuit is produced by the high-frequency electromagnetic coupled modes is transformed to civil power or the direct current that electrical appliance needs.This technical scheme mainly is to solve the trouble that traditional electrical appliance needs outer distribution transforming depressor, charger etc. targetedly, improves Electrical Safety simultaneously.
But close, exist between power supply and the load for miniature occasion, non-electromagnetic field under the occasion such as high-speed motion, thisly realize the transmission of electric energy by the high-frequency electromagnetic coupled modes, just inapplicable.
Summary of the invention
In order to solve fragile, stable bad that existing contact collecting ring exists, and adopt the electric supply installation of collecting ring to export to the supply current problem of unstable of load, the invention provides a kind of condenser type noncontact collecting ring and use the electric supply installation of described collecting ring.
Condenser type noncontact collecting ring is made up of first capacitor and second capacitor, first capacitor and second capacitor first electrode pad and second electrode pad separately can produce relative motion under the prerequisite that relative distance and relative area all remain unchanged, first electrode of first capacitor and first electrode of second capacitor are fixed together or keep being synchronized with the movement, second electrode of described first capacitor and second electrode of second capacitor are fixed together or keep being synchronized with the movement, and keep insulation between described first capacitor and second capacitor.
Condenser type noncontact collecting ring of the present invention is that to use between two pole plates of capacitor with the air be dielectric, realizes the electrical connection of noncontact mode by the gap between the pole plate.Appearance value and the distance between two pole plates of capacitor and the proportionate relationship of relative area according to capacitor, employing is in the work of condenser type noncontact collecting ring, and relative distance between two pole plates of each capacitor in the assurance collecting ring and relative area remain unchanged and make the capacitance of collecting ring constant.
The single appearance value that realizes non-contacting electric capacity is greater than 3pF at least, and AC signal is just apparent in view like this.The load resistance is 1M Ω, and when the single appearance value of electric capacity was 10pF, cut-off frequency can be 30kHz.If the load resistance is big more, the appearance value of electric capacity is big more, then can obtain lower cut-off frequency.If the ac frequency that provides is 100kHz, power factor can reach 95%.
Use the electric supply installation of condenser type noncontact collecting ring of the present invention to form by condenser type noncontact collecting ring, first high-frequency circuit and second high-frequency circuit, two outputs of first high-frequency circuit are connected with first electrode of first capacitor, first electrode of second capacitor respectively, second electrode of described first capacitor, second electrode of second capacitor are connected with two inputs of second high-frequency circuit respectively, and first electrode of described first high-frequency circuit and first capacitor, first electrode of second capacitor are fixedlyed connected or kept being synchronized with the movement; Second electrode of described second high-frequency circuit and described first capacitor, second electrode of second capacitor are fixedlyed connected or are kept being synchronized with the movement.
The operation principle of electric supply installation of the present invention is: condenser type noncontact collecting ring is a pair of capacitor, utilize the characteristic of the logical high frequency resistance low frequency of capacitor, give second high-frequency circuit with the electrical signal transfer of first high-frequency circuit in the electric supply installation, and then realized the purpose of the transmission of electric energy.
The advantage of electric supply installation of the present invention is: one, adopt high-frequency circuit ripe in the prior art as the transmission of electric energy, the device of conversion, good stability, reliability height; Two, adopt capacitor as the couple electrical energy device, avoided fully in the existing contact collecting ring supply power mode because a series of problems that CONTACT WITH FRICTION is brought also make the relative motion mode between power supply and the load also more flexible.
