Dispositivo de corte con pantalla de corte de arco

摘要

The device has a box with a fixed contact (12) cooperating with a movable contact (11) carried by a contact support arm (14), where the device is a unipolar, tripolar or quadripolar breaking device. A movable arc-breaking screen (13) is controlled in displacement to occupy rest and rolling positions when the contacts are in respective closing and opening positions. The screen is connected to the arm by an actuating rod (20), so that movement of the arm drives the movement of the screen. The rod is connected to the screen and the arm through rotational axes (Z2, Z3).
