    摘要: An electric circuit switchgear includes main contacts circumferentially arranged on a fixed panel and auxiliary contacts. The switchgear also includes a rotary electromechanical drive connected with a driving shaft and enabling the latter to be turned through a pre-set angle. The driving shaft is rotated together with an actuating element of an electromagnetic drive provided with a contactor and a disconnector both having at least one projection interacting with the main and auxiliary contacts through contact closing and disconnecting mechanisms having locks.

    摘要: On an insulating baseboard with a central opening there are located contacts. There are also auxiliary contacts intended for connecting local control circuits of the device. A rotational electromechanical drive is provided to rotate a contactor, and an electromagnetic drive is adapted to reciprocate said contactor for operating contacts. The electromagnet drive has an electromagnet for closing contacts and a plurality of electromagnets for opening contacts. The number of the electromagnets corresponds to the number of the contact fixing devices. The armature of each electromagnet is connected with one of the contact fixing devices.

    摘要: An electric circuit switching device comprises a group of closing contact pairs and a group of breaking contact pairs, each group having stationary contacts arranged circumferentially on an insulating panel, and a switching element; a unit for rotating the switching elements; and an electromagnetic drive providing translatory motion of the switching elements while closing and breaking the contact pairs. The unit for rotating the switching elements is a rotary electromechanical drive having a means for setting the angle of rotation of its output shaft depending on the position of the contacts to be switched on the insulating panel. The electromagnetic drive has two electromagnets, the first of which provides translatory motion of the switching element of the group of the closing contact pairs, and the second electromagnet providing translatory motion of the switching element of the group of the breaking contact pairs. Each electromagnet has a hollow core supporting a winding and embracing the output shaft of the rotary electromechanical drive, and an armature having a recoil spring rigidly connected to a respective switching element, electrically insulated from the switching element and mounted for movement along the output shaft. The group of the breaking contact pairs, apart from the stationary contacts, have spring-loaded contacts, each forming with one of the stationary contacts of said group a contact pair and being actuated by the switching element while breaking the contact pairs of said group.
