s1, when a drawer unit (3) on a power switch cabinet (1) needs to be pulled out, different operating handles are used for controlling a circuit breaker to open a main switch in the drawer unit (3), and the drawer unit (3) is unlocked and can be pulled out from a small device chamber (2);
s2, the pulley (43) rolls along the U-shaped magnetic track (45) in a guiding manner, so that the drawer unit (3) is pulled out outwards, and the U-shaped magnetic track (45) provides upward repulsive force for the magnetic ring embedded in the roller in the process, so that partial dead weight of the drawer unit (3) and internal installation equipment is offset, the pressure applied by the drawer unit (3) and the internal installation equipment to the pulley (43) can be reduced, the smoothness of rolling of the pulley (43) along the U-shaped magnetic track (45) is improved, and the force application required for pulling out the drawer unit (3) is effectively reduced;
s3, when the drawer unit (3) slides out through the pulley (43), the pulley (43) can drive the rubber disc (483) in the bracket (481) to rotate in the rolling process along the U-shaped magnetic track (45), at the moment, the hard tooth surface (485) on the surface of the rubber disc (483) synchronously drives the gear (484) and the rotating shaft (482) to rotate, and the coil (487) arranged on the rotating shaft (482) follows the rotating shaft (482) to perform circular motion in the U-shaped magnetic track (45), the U-shaped magnetic track (45) is provided with a magnetic field, free electrons in the coil (487) serving as a conductor are subjected to the action of the magnetic field force to generate directional movement, and thus, current is generated, that is, a part of the conductor in the closed circuit makes the motion of cutting magnetic induction line in the magnetic field, the electrons in the conductor will be subjected to Lorentz force, which is non-electrostatic force, and can cause potential difference, thereby generating current which is output from two electrodes of the coil (487) and input into the electromagnet (4810) through the anode copper ring (488) and the cathode copper ring (489) to generate magnetism, because the magnetic pole on the outer end surface of the electromagnet (4810) is the same as the magnetic pole on the corresponding surface of the U-shaped magnetic track (45) to generate repulsive force, and the electromagnet (4810) is disposed obliquely so that the repulsive force can apply an outward pushing force to the drawer unit (3) inside along the rail formed by the two U-shaped magnetic rails (45), thereby assisting an operator to pull out the drawer unit (3) and further reducing the pulling force required for operation;
s4, in the process of pulling the drawer unit (3) outwards, the turbine (4861) arranged on the rotating shaft (482) can rotate synchronously, the inner side of the U-shaped magnetic track (45) can be swept by a cotton sliver (4862) on the surface of the turbine (4861), meanwhile, the turbine (4861) conducts exhaust airflow from inside to outside, and dust and sundries possibly existing in the inner side of the U-shaped magnetic track (45) are blown away, so that self-cleaning of the power assisting module (4) is achieved, and stability of relevant magnetoelectric operation is guaranteed.
