Technical Field

The utility model relates to an electrostatic elimination field, concretely relates to clear away circuit of high-voltage static.

Static electricity is a static or non-flowing charge (a flowing charge forms a current). Static electricity is formed when charges are accumulated on an object or a surface, and the charges are classified into two kinds of positive charges and negative charges, that is, the static electricity phenomenon is also classified into two kinds, i.e., positive static electricity and negative static electricity. When positive charges are accumulated on a certain object, positive static electricity is formed, and when negative charges are accumulated on a certain object, negative static electricity is formed, but no matter the positive static electricity or the negative static electricity is, when an object with static electricity is contacted with a zero potential object (a grounding object) or an object with a potential difference, charge transfer can occur, namely, a spark discharge phenomenon is seen daily.
