The invention is provided for connection and disconnection of de-energised sections of an electric circuit. The electric disconnector comprises a frame, insulator-mounted sliding and fixed contacts, a ground terminal, drawing bars of the contacts and the ground terminal, and an electric drive mechanism. Higher convenience of operation and reliability are provided by the drive mechanism including a drive with a reducing gear and a reversible magnetic starter. A large and a small rotatable elements are mounted on the shaft of the reducing gear, the large rotatable element is linked to drawing bars, the rotatable elements are engageable with an end switch. The drive is connected to a remote control device. The remote control device may be provided with a blocking device with a key. |
