Description

technical field [0001] The invention relates to a device for detecting whether high-voltage equipment has high-voltage electricity, in particular to an equipotential high-voltage charged indicator. Background technique [0002] With the development of the national economy, the demand for electricity is also increasing. The application of high-voltage equipment in the power generation, distribution and transmission systems of the power system is becoming more and more extensive. Casualties and equipment damage, it is still necessary to configure live indicators on high-voltage power transmission and distribution facilities. The live indicator is a kind of prompt safety device installed directly on the high-voltage power transmission and distribution facilities, which can visually show whether the high-voltage power transmission and distribution facilities have operating voltage. When the high-voltage power transmission and distribution facilities have operating voltage, live ...
