The invention relates to a novel high-voltage electroscope for alternating currents and direct currents. The novel high-voltage electroscope is characterized by comprising a change-over switch, a detection probe, an insulating handle, an extension-type insulating rod and an acousto-optic display unit. The detection probe is arranged at the top end of the whole novel high-voltage electroscope, the lower portion of the detection probe is connected with the acousto-optic display unit, the extension-type insulating rod is arranged at the lower end of the acousto-optic display unit, the insulating handle is arranged at the lower end of the extension-type insulating rod, the change-over switch is arranged on the insulating handle and is connected with a change-over circuit through an internal connecting line, the acousto-optic display unit is controlled by an integrated circuit board, and the integrated circuit board is arranged in a box body on the upper portion of the extension-type insulating rod. According to the novel high-voltage electroscope for the alternating currents and the direct currents, when verification of a live part is conducted, the change-over switch on the end portion of the handle can be used for carrying out real-time switch to detect whether an alternating current transmission line and a direct current transmission line are charged, so that troubles that two types of electroscope devices need to be carried at the same time are eliminated, and the novel high-voltage electroscope for the alternating currents and the direct currents is convenient and fast to use.
Description
technical field [0001] The invention relates to a high-voltage electroscope, in particular to an acousto-optic indicating type electroscope for checking whether AC and DC lines are electrified, and belongs to the technical field of high-voltage transmission lines. Background technique [0002] With the rapid construction and commissioning of ultra-high voltage transmission lines, power line and equipment outage maintenance and live work are carried out rapidly. Among them, judging whether the line is live is very important to the safety of maintenance workers during power outages, and the electroscope is the most important tool for checking whether the line and equipment are live. At present, AC and DC line electroscopes use AC and DC electroscopes respectively, which cannot be used interactively. [0003] In view of this, the present invention provides an AC and DC high voltage electroscope to meet the needs of practical applications. Contents of the invention [0004] ...
