FIELD: electricity. ^ SUBSTANCE: breaker comprises a contact element and a displacement device. As the breaker closes and opens, the displacement device moves the contact element, and to open and close the breaker, it rotates the contact element (44) around the axis. The contact element (44) is installed on the shaft (D). The drive rotates the shaft (D) to open and close the breaker. The contact element has two contact surfaces (45, 46). In the closed position of the breaker one contact surface (45) is in contact with a bus bar (S), and the other contact surface (46) - with a conductor (43) installed in a case (41). The contact element (44) is installed radially on the shaft (D) with capability of displacement. ^ EFFECT: provision of reliable removal of the contact from the bus bar in case of sticking. ^ 2 cl, 7 dwg |
