| description | The utility model provides a breakdown-resistant current cut-off device, which is applied to a breaker and comprises an upper shell, a lower shell and a lower shell, the lower shell is connected with the lower part of the upper shell, and an avoiding hole extending up and down is formed in the lower shell; the electric conductor is arranged between the upper shell and the lower shell; and the cut-off grid sheet is arranged in the guide hole, is located above the electric conductor and can enter the avoiding hole after the electric conductor is cut off, and melamine coatings are arranged on the inner wall of the guide hole, the inner wall of the avoiding hole and the surface of the cut-off grid sheet. The beneficial effects of the utility model are that the electric arc generated in the breaking process of the breaking grid plate acts on the melamine coating during combustion, the electric arc is prevented from directly acting on the surface of the breaking grid plate and the inner walls of the guide holes and |
