Title:
INTELLIGENT INTEGRATED MEDIUM-VOLTAGE AC VACUUM SWITCHGEAR BASED ON FLEXIBLE SWITCHING-CLOSING TECHNOLOGY
Document Type and Number:
WIPO Patent Application WO/2016/150090
Kind Code:
A1
Abstract:
An intelligent integrated medium-voltage AC vacuum switchgear based on a flexible switching-closing technology, comprising a controller (24), and a vacuum switching tube (1), an insulator (9) and a 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), 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 can be accurately controlled, and "flexible" switching-closing is achieved; by means of an over-travel spring (11) built in the insulator (9), high enough pressure is provided between the movable contact (4) and fixed contact (2) of the vacuum switching tube (1) during closing, and bounce-free quick switching is achieved during switching; and in the switching and closing processes, the harmful impact on the power grid, loads and a switch is quite small, and a demand on construction of a strong intelligent power grid is met.
