Arrangement for improving the homogeneity of a insulating gas mixture in a gas-insulated electric means - or high-voltage device

摘要

An arrangement for improving the homogeneity of a insulating gas mixture in a gas-insulated electric means - or high-voltage device comprises a in a gas chamber (12) of the device of the circulating fan (2) as well as a drive unit for displacing of (2) into a rotational movement. The drive unit comprises a first and a second drive member, wherein the first drive member in a one connection opening (14) of the gas space (12) in a gas-tight manner which closes the connection enclosure (5) is accommodated, and the second drive member on the connection enclosure (5) can be plugged. The first drive unit comprises a in the connection enclosure (5) and which is mounted from the connection enclosure (5), - and in the gas space (12) extending into the rotary shaft (6), which at its in the gas space (12) end of the circulating fan (2), and a permanent magnet set (1), which at least one polar pair and uniformly on the periphery of the rotary shaft (6) is attached in a distributed manner. The second drive unit comprises an excitation coil (9), and a coil housing (10), in which the exciter coil (9) is mounted such that, after a mounting of the coil housing (10) on the connection enclosure (5) arranged coaxially with respect to the permanent magnet set (1) as well as the permanent magnet set (1) is arranged radially, wherein, after the mounting of the coil housing (10) on the connection enclosure (5) by means of the excitation coil (9) a rotating magnetic field is generated, which the permanent magnet set (1) and in the rotary shaft (6) with the circulating fan (2) in a rotational motion.
