The invention provides an intelligent temporary earthing device for 10KV overhead line maintenance and relates to an earthing device. With application of 3G videos on a construction site, field operation safety is further supervised, however, violation of laws and regulations still exists when very few workers remove temporary earthing wires. The intelligent temporary earthing device for 10KV overhead line maintenance comprises a main unit and a handheld unit wirelessly connected with the main unit, wherein the main unit is arranged on an earthing pin through a connecting piece and comprises a casing, a control panel arranged in the casing, a prompt device connected with the control panel and used for indicating an earthing condition of the earthing pin as well as a power supply used for supplying power to the control panel and the prompt device; an earthing resistance test circuit for measuring earth conductive resistance and a wireless communication module are arranged on the control panel.
