The non-magnetic electrical design of the zero-magnet laboratory is introduced:DC 220 V power supply is selected as the lighting power;AC power supply is used for experimental equipment;in order to improve the shielding effectiveness,the number of holes on the screen shall be minimized,the long side of holes shall be parallel to the magnetic flux direction,and circular holes shall be arranged symmetrically;shielded cables shall be used as distribution cables for experimental equipment;the distribution boxes shall be subject to shielding treatment.
