High-voltage spiral line voltage multiplier

The high-voltage spiral line voltage multiplier comprises an outer metal film, an inner metal film, a first insulating film and a second insulating film, the outer metal film and the inner metal film are of a spiral double-line winding structure, the first insulating film is arranged between the outer metal film and the inner metal film, and the second insulating film is arranged between the outer metal film and the inner metal film. A second insulating film is arranged between the inner side metal film and the outer side metal film, the outer side metal film and the inner side metal film are wound in a spiral double-line mode to form N turns of winding, and the central positions of any two adjacent turns at least have a set offset distance in the axis direction. The spiral line winding structure is optimized, the insulation distance is increased, the surface insulation effect is improved, the number of parts does not need to be increased or decreased, and the winding machining difficulty is basically not imp
