The invention discloses an electroscope dedicated to a 220 kV double bundle conductor and belongs to the technical field of power tools. The electroscope comprises an insulated and retractable hand-held lever, a first electroscope and a second electroscope, wherein the first electroscope and the second electroscope are arranged at the top of the hand-held lever. The hand-held lever comprises at least two sections of telescopic support rods, wherein adjacent support rods are hinged together. According to the technical scheme of the electroscope dedicated to the 220 kV double bundle conductor, the electroscope is simple in overall structure, and the hand-held lever is designed to be of a telescopic structure. Therefore, the length of the hand-held lever can be adjusted according to the height of a to-be-tested wire, so that the versatility of the entire electroscope is improved. The hand-held lever is provided with a display screen and a switch used for controlling the electroscope. A processor and a battery are arranged inside the hand-held lever. The electricity testing information acquired by the electroscope can be clearly displayed on the display screen. The working personnel can clearly know the electricity testing information through observing the display screen and is convenient to read data.
