Referring to fig. 3, in one embodiment of the present application, the electroscope 140 includes a voltage detection circuit 142, a detection control chip 143, a buzzer driving circuit 144, a buzzer 145, an LED indicator 146, and a battery 147. The voltage detection circuit 142 is electrically connected to the electroscope electrode 141, and the detection control chip 143 is electrically and signally connected to the voltage detection circuit 142. The buzzer driving circuit 144 is electrically connected and signal-connected with the detection control chip 143, and the buzzer 145 is electrically connected with the buzzer driving circuit 144. When the detection control chip 143 detects that the insulated wire 20 is electrified through the voltage detection circuit 142, the buzzer driving circuit 144 receives the electrified signal sent by the detection control chip 143, and drives the buzzer 145 to sound for reminding. The LED indicator 146 is electrically and signally connected to the detection control chip 143. Similarly, when the detection control chip 143 detects that the insulated wire 20 is charged, the detection control chip 143 may drive the LED indicator 146 to emit light, so as to perform a light emitting prompt. When the insulated wire 20 is not electrified, neither the buzzer 145 nor the LED indicator 146 may prompt, and the operator may continue the cable grounding operation. The electroscope 140 can facilitate a worker to ascertain whether the cable is charged or not, thereby increasing the safety of operation. The battery 147 is electrically connected to the detection control chip 143, and the battery 147 may supply power to the detection control chip 143.
