Abstract
High voltage circuit breaker switches controlling means, relate to high voltage circuit breaker technical field, including closing coils, the separating brake coil, the eddy -current disc, remove the axle, bistable dish spring, remove the cover, the fixed axle, insulator and vacuum interrupter, the eddy -current disc is fixed and is being removed epaxially and be located between separating brake coil and the closing coils, the eddy -current disc parallel and can remove between separating brake coil and closing coils through removing the axle with separating brake coil and closing coils respectively, the tip of the axis is being removed to fixed setting of bistable dish spring, remove the fixed front end that sets up at the removal axle of cover, the fixed axle nestification is inboard at the front end that removes the cover, the insulator sets up on the fixed axle, the fixed front side that sets up at the insulator of vacuum interrupter. The utility model relates to a rationally, it is little that the eddy -current disc removes the burden, and the floodgate speed of action that opens and shuts is fast, operation long service life, can effectively avoid " voltage falls suddenly " perhaps " to shake " the phenomenon causing the loss for the enterprise, reliably spend highly.
Description
Technical field:
The utility model relates to primary cut-out device technique field, specifically primary cut-out switching control.
Background technology:
Plain edition vacuum circuit-breaker opening time generally wants 40 ~ 60ms; add relay protection operate time and arcing time; disengagement failure at least wants more than 80ms; and closing time decentralization too large (reaching ± 7ms most); this short-circuit current rush that relevant device maturation 3 ~ 5 times not only will be made large; and due to the serious reduction (namely usually said " voltage falls suddenly " or " shake electricity ") of busbar voltage; control the under-voltage protection of important production equipment and the release of contactor by causing, and cause the accident of being forced to stop production of enterprise thus.Avoid the stopping production accident that the phenomenon of " voltage falls suddenly " or " shaking electric " causes to enterprise, within just the opening time of vacuum circuit-breaker must being shortened to 5ms, Fast Speed Vacuum Circuit Breaker comprises K Quick drive mechanism, existing driving mechanism still needs the longer switching time, effectively can not avoid the adverse effect that " voltage falls suddenly " or " shaking electric " phenomenon is brought to enterprise, and in prior art when divide-shut brake eddy-current disc can wholely drive when mobile on rear side of insulator and the movement of vacuum interrupter, weight when considerably increasing mobile, also the reaction time of control device can be reduced.
Utility model content:
It is fast that technical problem to be solved in the utility model is to provide a kind of switching speed, can avoid the primary cut-out switching control of " voltage falls suddenly " or " shaking electric " phenomenon.
Technical problem to be solved in the utility model adopts following technical scheme to realize:
Primary cut-out switching control, it is characterized in that: comprise closing coil, switching winding, eddy-current disc, shifting axle, state dish spring device, movable sleeving, fixed axis, insulator and vacuum interrupter, described eddy-current disc to be fixed on shifting axle and between switching winding and closing coil, eddy-current disc is parallel with switching winding and closing coil respectively and can be moved between switching winding and closing coil by shifting axle, described state dish spring device is fixedly installed on mobile the tip of the axis, described movable sleeving is fixedly installed on the front end of shifting axle, described fixed axis is nested in the leading inside of movable sleeving, described insulator is arranged on fixed axis, described vacuum interrupter is fixedly installed on the front side of insulator.
The inner side of described movable sleeving and the junction of fixed axis are provided with cod.
The beneficial effects of the utility model are: the utility model is reasonable in design, and it is little that eddy-current disc moves burden, switching quick action, operation long service life, can effectively avoid " voltage falls suddenly " or " shake electricity " phenomenon to cause damage to enterprise, and reliability is high.
Accompanying drawing illustrates:
Fig. 1 is the utility model principle mechanism schematic diagram.
Embodiment:
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the utility model further.
As shown in Figure 1, primary cut-out switching control, comprise closing coil 1, switching winding 2, eddy-current disc 3, shifting axle 4, state dish spring device 5, movable sleeving 6, fixed axis 7, insulator 8 and vacuum interrupter 9, eddy-current disc 3 to be fixed on shifting axle 4 and between switching winding 2 and closing coil 1, eddy-current disc 3 is parallel with switching winding 2 and closing coil 1 respectively and can be moved between switching winding 2 and closing coil 1 by shifting axle 4, state dish spring device 5 is fixedly installed on the end of shifting axle 4, movable sleeving 6 is fixedly installed on the front end of shifting axle 4, fixed axis 7 is nested in the leading inside of movable sleeving 6, insulator 8 is arranged on fixed axis 7, vacuum interrupter 9 is fixedly installed on the front side of insulator 8.The inner side of movable sleeving 6 and the junction of fixed axis 7 are provided with cod 10.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
