The invention relates to a capacitive high-voltage acousto-optic electroscope without an electricity verification dead zone. The capacitive high-voltage acousto-optic electroscope comprises a base part, a connecting part, an anti-interference electrode and a control circuit. The base part is coaxially provided with the connecting part, and the connecting part is coaxially provided with the anti-interference electrode. One end of the anti-interference electrode extends out of the connecting part to be used as an exposing section and used for electricity verification detection, and the other end of the anti-interference electrode is connected with the control circuit to be connected with an alarm device. According to the capacitive high-voltage acousto-optic electroscope without of the electricity verification dead zone, the electrode and the connecting circuit on the electroscope are replaced and adjusted, the problem that the electricity verification dead zone exists on electrical equipment is effectively solved, the electroscope is sensitive and accurate, human body injuries, malicious misoperation accidents and equipment accidents are avoided, and it is guaranteed that an electric system can operate safely.
