Abstract

The invention provides a high-voltage electric display device. The device comprises a noncontact sensor and a controller which are interconnected, wherein the noncontact sensor is used for measuring the electricity of an electric body in a noncontact manner; the controller comprises a display module which is used for displaying the detection result of the noncontact sensor. With the adoption of the device, the problem of difficult electricity measuring and low reliability of a conventional high-voltage electric display device can be solved; the noncontact measuring is carried out to the strength of electric fields surrounding the electric body through the noncontact sensor in order to detect whether the electric body is electric, and the problem that the electric body is in non-electric connection which leads to breakdown damage of a capacitor can be avoided; the detection is simple; the detection result is displayed through the display module; the high-voltage electric display devicecan be rapidly overhauled; and the reliability can be improved.

Description

technical field [0001] The invention relates to the technical field of electric equipment detection equipment, in particular to a high-voltage charged display device. Background technique [0002] The high-voltage charged display device can transmit the signal of whether the high-voltage charged body is charged or not to the light-emitting or audio components; while most of the existing 10KV switchgear live display devices have been running for more than 10 years, the equipment is aging, and the equipment is defective. many. [0003] At present, the sensor of the live display device of the switchgear is installed in the form of an insulator. It is difficult to replace after damage, and most of them are installed in a three-phase integrated installation. One of the phases is damaged and the entire device needs to be replaced. When replacing, it needs to be repaired and replaced by power failure. Affect the reliability of continuous power supply. The existing switchgear live...
