Abstract

A cable fault indicator comprises a fixing bracket and a shell. The shell is a light guiding shell, and a solar panel, a lithium battery, an adjusting circuit, an AC sampling coil and a processing unit are arranged in the shell; the solar panel is connected with the lithium battery, and a signal sampled by the AC sampling coil is transmitted to the processing unit via the adjusting circuit. The shell of the fault indicator can guide light, the solar panel in the shell can receive the sunlight to generate power itself and supply the generated power to the lithium battery to charge, so that the lithium battery can supply with the fault indicator with power for a long time and stably. The AC sampling coil acquires the signal of a cable, and after the signal is processed by the adjusting circuit, a stable and reliable AC signal is provided and sent to the processing unit, thereby achieving the purposes of keeping the reliable running of the fault indicator and detecting fault accurately.

Description

A kind of cable fault indicator
Technical field
The utility model relates to fault detector.
Background technology
Known technology is at present, and known fault detector is to be made by disposable AA alkaline battery power supply, CT power taking power supply, direct current signal sampling on the market.Its shortcoming is: because the AA alkaline battery is not chargeable, the long-time back electric weight that uses uses up, and fault detector can not be worked; Adopt the CT power taking, when the following electric current of power line transmission 20A, enough electric weight can't be provided, when the above electric current of power line transmission 1000A, possibly damage feed circuit, cause indicator to work; Direct current signal sampling, special distorted waveform in the time of can't accurately measuring transmission line fault causes difficulty to fault detect, causes misjudgment easily.
Summary of the invention
The utility model technical matters to be solved provides a kind of cable fault indicator, and solution existing fault indicator can not be supplied power for a long time, stable power-supplying, and the inaccurate problem of fault detect.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of cable fault indicator; Comprise fixed support and shell, said shell is the leaded light shell, is provided with solar panels, lithium battery, adjustment circuit, AC sampling coil and processing unit in the said shell; Said solar panels are connected with said lithium battery, and the signal that said AC sampling coil sampling obtains is transported to said processing unit through said adjustment circuit.The shell of fault detector can leaded light, and the solar panels in the shell can be accepted sunlight and generating voluntarily, and the electricity that solar panels will send is supplied with lithium cell charging, makes lithium battery can be long-term and stable fault detector is supplied power; The AC sampling coil is gathered the signal of cable, and signal provides reliable and stable AC signal and sends into processing unit, thereby reach the fault detector reliability service through the adjustment circuit, accurately the purpose of detection failure.
As improvement, said lithium battery is a ferric phosphate lithium cell.
As improvement, said AC sampling coil is installed in said fixed support below, and fixed mount is used for fault detector is fixed to cable, and easy for installation its in the position of AC sampling coil carries out the collection of signal to cable.
As improvement, the plate face of said solar panels pastes with said outer casing inner wall mutually.
As improvement, be provided with mu balanced circuit and charging circuit in the said shell, said solar panels are connected with said lithium battery with charging circuit through said mu balanced circuit.
The beneficial effect that the utility model is compared with prior art brought is:
1, the shell of fault detector can leaded light, and the solar panels in the shell can be accepted sunlight and generating voluntarily, and the electricity that solar panels will send is supplied with lithium cell charging, makes lithium battery can be long-term and stable fault detector is supplied power;
2, have security, the feature of environmental protection, advantage that cycle index is high with ferric phosphate lithium cell;
3, the AC signal sampling can be gathered complete sign mutation waveform, improves the reliability of fault detector work, accuracy.
Description of drawings
Fig. 1 is the utility model circuit theory diagrams.
Fig. 2 is the utility model cut-open view.
Embodiment
Below in conjunction with Figure of description the utility model is further specified.
As shown in Figure 2, a kind of cable fault indicator comprises fixed support 5 and shell 1, and said fixed support 5 is located at said shell 1 top, is used for fault detector is fixed on cable; Said shell 1 is the leaded light shell, shell 1 shown in light can penetrate.Be provided with solar panels 2, lithium battery 6, adjustment circuit 3, mu balanced circuit, charging circuit, AC sampling coil 4 and processing unit 7 in the said shell 1.Said lithium battery 6 is a ferric phosphate lithium cell, has security, the feature of environmental protection, advantage that cycle index is high; Said AC sampling coil 4 is installed in said fixed support 5 belows, makes things convenient for it cable to be carried out the collection of signal; The plate face of said solar panels 2 pastes with said shell 1 inwall mutually, makes the light-receiving area of solar panels 2 big as much as possible, improves its delivery.As shown in Figure 1, solar panels 2 are connected with interface (J101), and lithium battery 6 is connected with interface (J102), and promptly said solar panels 2 are connected with said lithium battery 6 with charging circuit through said mu balanced circuit; The AC sampling coil links to each other with interface (J201), sample resistance (R200), current-limiting resistance (R201), adjustment circuit 3, and the signal that promptly said AC sampling coil 4 samplings obtain is transported to said processing unit 7 through said adjustment circuit 3.The shell 1 of fault detector can leaded light, and the solar panels 2 in the shell 1 can be accepted sunlight and generating voluntarily, and the electricity that solar panels 2 will send is supplied with lithium battery 6 chargings, makes lithium battery 6 can be long-term and stable fault detector is supplied power; AC sampling coil 4 is gathered the signal of cable, and signal provides reliable and stable AC signal and sends into processing unit, thereby reach the fault detector reliability service through adjustment circuit 3, accurately the purpose of detection failure.
