Abstract
The utility model relates to a power source inductor which is provided with two iron cores and two windings. One of the iron cores is a closed iron core. A winding winds around the iron core. A hollow winding approaches to the winding. A section of unclosed iron core is inserted in the middle of the hollow winding. The homonymy terminals of the two windings are connected with each other. The other two terminals of the two windings export induced voltage. The utility model can induct stable voltage and provide the stable voltage for a corresponding electronic device. Thereby, the power source inductor not only can guarantee the normal operation of the electronic device but also can prevent the electronic device from damage caused by too high voltage.
Description
Technical field
The utility model relates to a kind of power induction device.
Prior art
In the online detection of high-tension apparatus, in order to obtain working power at the electronic installation of high-pressure side work, often utilize the voltage of the induction by current generation of passing through in the high-tension apparatus bus to be used as working power, traditional power induction device is generally single coil, and the work ferromagnetic core also adopts single magnetic core.Such power induction device can only primary current among a small circle in variation can obtain desirable working power, when the primary current wide variation, supply voltage will occur and cross low or too high phenomenon, thereby corresponding electronic installation can not be worked or damage, for addressing this problem, once had methods such as adopting the particular iron core material to solve, but effect is undesirable.
Summary of the invention
The purpose of this utility model provides a kind of power induction device, and it can induce a stable voltage, and offers its corresponding electronic installation, thereby can not only guarantee this electronic installation operate as normal, can also protect this electronic installation, prevents overtension and damages.
The utility model is to constitute like this, it has two iron cores and winding, one of them is iron core-closed, twining a winding round iron core, also having a hollow winding near this winding, insert one section inc iron core in the middle of the hollow winding, the end of the same name of two windings links together, two other terminal output induced voltage of two windings.
The utility model is owing to adopt unique double-iron core biquadratic loop construction, so have when having reached primary current and changing the advantage of the ideal effect that the secondary out-put supply is basicly stable on a large scale.
Description of drawings
Fig. 1 is the structure block diagram of the utility model embodiment.
Fig. 2 is that the winding of the utility model embodiment connects block diagram.
Among Fig. 11 is the primary current bus.
Embodiment
Further specify operation principle of the present utility model below in conjunction with embodiment and accompanying drawing.
As depicted in figs. 1 and 2, be provided with two iron cores and winding, one of them is iron core-closed 2, twining a winding 3 round iron core, also having a hollow winding 5 near this winding, the end of the same name that inserts 4, two windings of one section inc iron core in the middle of the hollow winding links together, two other terminal output induced voltage of two windings.The iron core-closed and not iron core-closed permeability magnetic material that all adopts here.
Its operation principle be the inductor iron core be divided into iron core-closed with not iron core-closed, iron core-closed at primary current hour, the magnetic line of force makes around thereon first induction coil in can active set bigger voltage output, when primary current is big, this iron core is with the more leakage flux of saturated generation, not iron core-closed near iron core-closed place, when primary current is big, leakage flux will second coil-inducedly go out voltage on not iron core-closed by not iron core-closed making, second coil is connected in series with first coil is anti-phase, when the big electric current in primary circuit, can effectively offset the overvoltage in first coil, overall output voltage is kept within the specific limits, thereby meet the demands.
