Abstract
The magnetic fluid sealing device is composed of non-magnetic seat, bearing, magnetic pole, permanent magnet, magnetic axis and magnetic fluid. Under the action of uniform and stable magnetic field, the magnetic fluid is filled in the set space and a multi-stage "O-ring" is established. In this article, the main components of magnetic fluid seals are studied experimentally, and the factors affecting the sealing ability of magnetic fluid seals, including the performance of magnetic rings and magnetic fluids, are analyzed. Through the analysis of experimental data, the reliability of magnetic fluid seal used in SF6 insultedswitchgear is summarized.
