Abstract: A plasma jet generator includes a base, a jet gun cavity, a blocking insulating medium, a porous air intake plate, a high-voltage port, a high-voltage electrode housing, and a jet gun tip. The base is detachably connected to a first end of the jet gun cavity. The blocking insulating medium is inserted in the base. The porous air intake plate is detachably mounted in the blocking insulating medium. The high-voltage electrode housing is detachably mounted in the porous air intake plate. The high-voltage port is disposed in the high-voltage electrode housing. The jet gun tip is detachably mounted at a second end of the jet gun cavity.

Abstract: Provided are an overhead line detection method and system based on a cable inspection robot. The cable inspection robot is suspended on the overhead line. An imaging unit and a laser emission unit are disposed at the front end of the cable inspection robot. The imaging unit is at a first angle to the overhead line. The laser emission unit is at a second angle to the overhead line.
