The invention provides a charge indicator of a high-voltage power transmission line. The charge indicator comprises an electricity obtaining unit, an adjusting unit and an indicating unit, wherein the electricity obtaining unit is arranged on the high-voltage power transmission line and obtains electricity from the high-voltage power transmission line in a sensing mode, the input end of the adjusting unit is electrically connected with the output end of the electricity obtaining unit, the adjusting unit is used for outputting stable direct-current electricity, and the indicating unit is electrically connected with the output end of the adjusting unit and is used for charge indication of the high-voltage power transmission line. According to the charge indicator of the high-voltage power transmission line, the whole device is powered up in an isolating electricity obtaining mode, the charge indicator has no contacts with the high-voltage power transmission line, and safety potential risks are avoided. The charge indicator can clearly indicate that whether the high-voltage power transmission line is charged or not, can send out fault information timely when the high-voltage power transmission line has a fault, can indicate the position where the fault appears, enables overhaul personnel to have a strong purpose in the overhaul process, facilitates timely elimination of the fault, improves work efficiency, and saves manpower.
Description
technical field [0001] The invention relates to a charging indicating device, in particular to a charging indicating device for a high-voltage transmission line. Background technique [0002] The high-voltage transmission line is a transmission line that transmits the electric energy produced by the power plant to a distant power destination. The high-voltage method is used to reduce the loss of electric energy and the use of wire materials. [0003] During the process of transmitting electric energy on high-voltage transmission lines, due to the influence of the external environment, faults such as short circuit or no electricity sometimes occur, which have a negative impact on the production and life of the destination of electricity. The method of searching for the line segment by segment is extremely inefficient, aggravates the negative impact on the production and life of the destination of electricity consumption, and wastes manpower; Bring great potential safety haza...
