A fluid multiple antielectricity device is composed of an entry joint (1), an insulating tube (2), a magnetic screen cover (3), a permanent magnet (4), a zero terminal (5), a zero gauze screen (6), an earth termina (7), an earth gauze screen (8) and an outlet joint (9), which is characterized in that, the zero gauze screen connected with the zero line and the zero gauze screen connected with the ground are provided in the pipe of the insulating tube, the permanent magnet is arranged on the two sides of the insulating tube caliber, and the outside of which is provided with magnetic screen cover. The insulating tube is used to prevent the current passing through the pipe wall, and the fluid in the insulating tube has a bulk resistance with the inhibition to the current; the permanent magnet constitutes the magnetic mirror having the magnetic confinement to the electrical carrier in the fluid, which advances the fluid bulk resistance; the zero gauze screen is provided to make the potential of the fluid flowing through the zero gauze screen as the zero line potential; the earth gauze screen is provided to make the potential flowing through the earth gauze screen as the earth potential. The device is reliable with multiple functions.
