Abstract

The invention discloses a special auxiliary detection tool for power distribution ultrahigh frequency detection, which comprises a telescopic insulating rod, an ultrahigh frequency sensor bracket, a universal joint and an electric hydraulic push rod. One end of the universal joint is fixedly mounted at the center of the lower surface of the ultrahigh frequency sensor bracket through a bolt; the other end of the universal joint is fixedly connected with the telescopic insulating rod through a bolt; according to the invention, the ultrahigh-frequency partial discharge detection work can be carried out on the distribution network pole-mounted switch and the isolation switch without climbing a pole by a detector, internal discharge hidden dangers of the distribution network pole-mounted switch and the isolation switch can be found in time, the fault rate of the distribution network pole-mounted switch and the isolation switch is reduced, and the operation reliability of the distribution network pole-mounted switch and the isolation switch is improved; moreover, the detection personnel do not need to be close to the electrified equipment, thereby preventing the electrified equipment from causing personal injury to the detection personnel, and improving the safety of the ultrahigh-frequency partial discharge detection work of the distribution network pole-mounted switch and the isolation switch.

Description

technical field [0001] The invention relates to the technical field of power distribution UHF detection, in particular to a special auxiliary detection tool for power distribution UHF detection. Background technique [0002] At present, the traditional operation and maintenance of switches and isolating switches on the distribution network column is mainly to carry out personnel inspection, infrared imaging and ultrasonic discharge detection work, and it is impossible to find the internal discharge hidden dangers of the switch on the column and the isolating switch in time; with the new technology of UHF partial discharge detection In the exploration and application of distribution network, UHF partial discharge detection has become an important method for the internal discharge detection of pole-mounted switches and disconnectors, and there are two difficulties in the detection process. [0003] In view of the fact that the switch and isolating switch on the distribution gr...
