The invention discloses electrified spraying equipment. The electrified spraying equipment comprises an external insulating pipe, wherein the outer insulating pipe coaxially sleeves an inner insulating pipe; the inner insulating pipe can do reciprocating motion along the axial direction of the outer insulating pipe and stretches out of the front end of the outer insulating pipe; an operation head matched with a spraying container is arranged at the front end of the inner insulating pipe; a pressing head, which is in contact adaptation with the spraying container, is hinged to the top of the operation head; a manipulation device, which is linked with the inner insulating pipe and the pressing head, is arranged at the rear part of the outer insulating pipe; and the outer insulating pipe is internally provided with a resetting device matched with the rear end part of the inner insulating pipe. The electrified spraying equipment disclosed by the invention can realize electrified work of spraying maintenance and the working efficiency is relatively high. The invention further discloses an electrified spraying method applying the electrified spraying equipment.
