Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.Be understandable that, specific embodiment described herein is only for explaining the present invention, but not limitation of the invention.It also should be noted that, for convenience of description, in accompanying drawing, only show part related to the present invention but not entire infrastructure.
Referring to Fig. 1, disclose according to the current power supply device of wire power taking of the present invention, it is characterized in that: there are two " iron cores of [" type in the both sides of wire 1, two described iron cores are mutually symmetrical with respect to described wire, and the described wire of sealing ground encirclement, after an iron core, being wound with induction coil 3 therein, described coil and described iron core form CT iron core, that is to say, described CT iron core is two halves open type.Between the two-phase of described induction coil, be in series with successively protective circuit; current rectifying and wave filtering circuit and voltage stabilizing circuit; wherein; the heavy current impact of described protective circuit for preventing that on wire, moment occurs; described current rectifying and wave filtering circuit carries out rectification and filtering for the voltage of realizing generating; described voltage stabilizing circuit provides voltage stabilizing function, and then an available power supply device is provided.
Preferably, described protective circuit can comprise two series connection or coil in parallel, thereby forms one group of coil, at the two ends of described one group of coil parallel discharge pipe, piezo-resistance and Transient Suppression Diode respectively, and then the upper associate coil of series connection.Described protective circuit can, in the time that metal-oxide-semiconductor is slow in one's movements, realize defencive function.
In the time using, " iron core of [" type, rests against wire below by power supply device, and then closing, " iron core of [" type makes wire navigate within two " between the iron core of [" type to open one of them.The changes of magnetic field of induction coil inductive iron core, generates electric current, and through protective circuit 4, current rectifying and wave filtering circuit 5 and voltage stabilizing circuit 7 are exported available current.
Preferably; it is described that " iron core of [" type is arranged on spherical housing; described induction coil is wrapped in described spherical housing; and corresponding one of them iron core; like this; can be convenient to provides and installs and protection power supply device of the present invention, and spherical housing can compress two " [" shaped iron cores in the time closing up.
