7. The conductive slip ring as claimed in claim 4, wherein two sets of air ducts (11) are provided in the cavity, the two sets of air ducts (11) being provided on either side of the rotor member (4).

8. The conductive slip ring as claimed in claim 7, wherein the positions of the air-guide holes (111) are in one-to-one correspondence with the positions of the copper rings (41).

9. The conductive slip ring as claimed in claim 8, characterized in that the gas guiding direction of the gas guiding hole (111) is tangential to the copper ring (41).

10. Conductive slip ring according to claim 9, characterized in that two air-guide holes (111) are arranged on the same section of the air-guide tube (11), and the directions of the two air-guide holes (111) are tangential to the two sides of the circular surface of the copper ring (41).
