In this paper, we introduced the theory of static electricity protection for heating and pasting equipment.Conductors were electrically conductive objects, in which there were free to move the charge; we studied the metal conductor, which was characterized by the existence of lots of free movement of internal electrons.Due to the characteristics of the metal conductor in the electric field, the role of electric field would be force the free electrons to move in the conductor surface charge redistribution phenomenon.When there was no charge in the conductor for the state of the static movement of static equilibrium.The static equilibrium states and conditions were analyzed theoretically, respectively.
