The electronic circuit is composed of an oscillation frequency conversion part, a voltage boosting rectification filtering part, a detection part, etc., and is also provided with a monitoring circuit which is used for monitoring the working voltage and the detection result. The outer shell is provided with a detection draw rod. When in use, the detection draw rod is overlapped on the insulator, and the microammeter displays the measured result. The utility model has the advantages of simple structure and convenient operation.
Description
The utility model relates to a kind of suspended insulator detecting device that uses that is applicable under power-off condition.
Detection for insulator is to adopt a kind of insulation megger at present, owing in the table microgenerator is arranged.Need two people during operation, people's megger, another people detection, also generator need the megger people shake speed and the time that reaches certain, reach rated voltage, could detect insulator, therefore, speed is slow, and needs workman's operation.
It is power supply by electric battery that the purpose of this utility model provides a kind of, has the suspended insulator detecting device of electronic boost-up circuit.
The utility model structure is made of movement and shell as shown in drawings.Respectively there is a detection pull bar both sides, upper end of its shell.Its movement is made of testing circuit and monitor alarm circuit, and its testing circuit comprises vibration frequency conversion, the parts such as rectifying and wave-filtering and measurement of boosting.Monitoring circuit is made of luminous and the part of reporting to the police.
Using method of the present utility model is that the detection pull bar is overlapped on metal position, insulator two ends, presses power switch, can demonstrate the data that record from microampere meter.
Principle of work of the present utility model is; Be overlapped on metal position, insulator two ends at the detection pull bar, energized, its oscillatory circuit work, transformer B
