| description | The utility model relates to the technical field of high-voltage electric checking, in particular to an intelligent non-contact type high-voltage electroscope. The intelligent non-contact type high-voltage electroscope comprises a parallel plate capacitor, a multi-path analog switch, a differential amplification circuit, a rectification filter circuit, a single chip computer and a voice alarm circuit, wherein the parallel plate capacitor, the multi-path analog switch, the differential amplification circuit, the rectification filter circuit, the single chip computer and the voice alarm circuit are electrically connected sequentially, and a self-checking signal is input into the multi-path analog switch. The utility model realizes non-contact electric checking and has high response speed. In the electric checking process, a proper alarm threshold is automatically selected aiming at different voltage grades (220V to 1000KV), the electric checking of a measured object with the voltage grade of 220V to 1000KV is r |
