Device for e.g. cleaning high-speed wire, has dielectric small tube portion surrounding channel and arranged in plasma nozzle such that channel is partially electrically insulated against discharge space that is formed within plasma nozzle

摘要

The device (2) has a plasma nozzle (4) producing an atmospheric plasma jet (6), and a discharge space (10) formed within the nozzle with a nozzle opening (12) for outlet of the plasma jet. A channel (20) is formed between an intake opening (16) of the nozzle and the nozzle opening such that a wire (22) to be treated is passed via the channel. A dielectric small tube portion (30) surrounding the channel is arranged in the nozzle such that the channel is partially electrically insulated against the discharge space. The dielectric material is a high temperature insulator, quartz glass or ceramic. An independent claim is also included for a method for treating a conductive material wire.
