The utility model has been owing to adopted technique scheme, and by powering from electricity getting device logarithm word wireless malfunction indicating device, the user does not again worry the battery loss replacing lithium battery that totally also will have a power failure, and realizes non-maintaining fully.
Description of drawings
Fig. 1 is that the utility model is from the structural representation of power taking digital radio fault detector from electricity getting device.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Figure 1 shows that the utility model is from power taking digital radio fault detector, comprise from electricity getting device, described single-chip microcomputer 1, electricity-fetching module 2, the power taking magnet ring 3 that connects successively that comprise from electricity getting device, be wound with power taking coil 4 on the described power taking magnet ring 3, described electricity-fetching module 2 connects described power taking coil 4, described power taking magnet ring 3 is sheathed on the high-voltage conducting wires 5, and described electricity-fetching module 2 is provided with voltage stabilizing output interface 8.Described electricity-fetching module 2 is by storage capacitor 7 ground connection.Described single-chip microcomputer 1 is a ultra low-power microcontroller.Described single-chip microcomputer 1 is connected with backup battery 6.
During use, the electric fault indicating device of asking for is positioned on the ultra-high-tension power transmission line (perhaps switch cubicle busbar) of 10KV/20KV, the high initial permeability magnetic material magnet ring of sealing produces electromagnetic induction, when having electric current to pass through on the high-tension line, according to electromagnetic induction principle, the formation induced electromotive force, process process filtering then-＞rectification-＞voltage stabilizing-＞monitoring-＞feedback-＞processing procedures such as energy storage, formation is stablized 3.6V voltage and is exported.
By adopting the CPU processor chips of super low-power consumption, monitor front end aanalogvoltage comparison circuit in real time, change to form according to the fluctuation up and down of voltage and feed back to the power supply processing section, thereby realize the stability of voltage.Overvoltage protection has been adopted in circuit inside, even abnormal conditions occur, also guarantees to make voltage output can not exceed the 0.7v of the voltage that will export, thereby realizes the overvoltage protection of voltage.Fault detector inside partly is provided with resettable fuse from electricity getting device, even abnormal conditions occur, when electric current during greater than 2A, resettable fuse disconnects, and fault detector power taking part is not worked; When electric current during less than 2A, resettable fuse is resumed work, and is engaged in and realizes self-healing overcurrent protection.
