Abstract

The invention discloses an electric power electronic electroscope, and belongs to the technical field of electric power electronic application. The electric power electronic electroscope comprises a signal receiving end, a slide rheostat, an inductor, a switch, an integrated circuit, a loudspeaker and a light-emitting diode. The signal receiving end is grounded via the slide rheostat. The sliding end of the slide rheostat is electrically connected with a third pin of the switch. A second pin of the switch is electrically connected with the signal receiving end via the inductor. A first pin of the switch is electrically connected with the second pin of the integrated circuit. The first pin of the integrated circuit is electrically connected with a high electrical level, the third pin is electrically connected with a power supply directly, a fourth pin is electrically connected with the power supply via the loudspeaker, a fifth pin is electrically connected with the power supply via the light-emitting diode and a sixth pin is grounded. Beneficial effects are that the electric power electronic electroscope is simple in structure, easy to realize, low in cost and high in reliability so that electricity verification in a long distance way can be realized and a charged boundary can also be judged in a short distance way.
