  • Intelligent integrated medium-voltage AC vacuum switchgear based on flexible switching-closing technology
    Patent number: 10573474
    Abstract: An intelligent integrated medium-voltage alternating current (AC) vacuum switchgear based on a flexible switching-closing technology comprises a controller (24), and a vacuum switching tube (1), an insulator (9), and an switching-closing mechanism connecting piece (15), which are connected in sequence. A microprocessor is built in an intelligent circuit (23); a travel sensor is fixed to a movable contact connecting rod (5), and directly detects a motion state of a movable contact (4) and acquires accurate motion parameters of the movable contact (4); switching-closing operating parameters are obtained by comprehensively calculating arc light intensity detected by an arc light transmitter (20) and a temperature measured by an infrared temperature measuring transmitter (22), such that the switching-closing performance of switching on and switching off a medium-voltage power grid is greatly improved, switching-closing time points are accurately controlled, and “flexible” switching-closing is achieved.
