Description
Technical field:
The present invention relates to fast vacuum switching device technical field, specifically is quick eddy current driving mechanism.
Background technology:
Plain edition vacuum circuit-breaker opening time is generally wanted 40～60ms; add relay protection operate time and arcing time; disengagement failure is wanted more than the 80ms at least; and the closing time decentralization too big (reach most ± 7ms); this not only will make 3～5 big short-circuit current rushes of relevant device maturation; and because the serious reduction (being usually said " voltage falls suddenly " or " rolling ") of busbar voltage; to cause controlling the under-voltage protection of important production equipment and the release of contactor, and cause the accident of being forced to stop production of enterprise thus.The stopping production accident of avoiding the phenomenon of " voltage falls suddenly " or " rolling " to cause to enterprise, just must shorten to the opening time of vacuum circuit-breaker in the 5ms, Fast Speed Vacuum Circuit Breaker comprises K fast driving mechanism, existing driving mechanism still needs long folding lock time, the adverse effect that can not effectively avoid " voltage falls suddenly " or " rolling " phenomenon to bring to enterprise.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of folding lock speed fast, can avoid the quick eddy current driving mechanism of " voltage falls suddenly " or " rolling " phenomenon.
Technical problem to be solved by this invention adopts following technical scheme to realize:
Quick eddy current driving mechanism, it is characterized in that: comprise charge power supply, be connected in parallel on combined floodgate storage capacitor and the separating brake storage capacitor at charge power supply two ends, described combined floodgate storage capacitor and separating brake storage capacitor two ends are combined floodgate discharge switch in parallel and separating brake discharge switch respectively, one end of combined floodgate discharge switch and separating brake discharge switch is connected with closing coil and switching winding by lead respectively, be provided with eddy-current disc between switching winding and the closing coil, fixedly there is straight-bar in the centre position of eddy-current disc, be positioned at the switching winding outside on the straight-bar and be connected with insulator, the end that is positioned at the insulator outside of straight-bar is provided with vacuum interrupter.
