Multi-disc iron plate on described iron core is all longitudinally arranged and is stacked together, and the thickness range of every sheet iron plate is between 1-2mm.To increase the quantity of the iron plate on iron core to greatest extent, to form more gap, reach and better stop vortex flow, reduce eddy current.
Described connecting lever is L shape structure, also arranges latch in the bottom of connecting lever, also arranges in the indentation, there of conducting rod the bayonet socket mated with latch.Connecting lever is connected more firm with conducting rod.
The thickness of described draining ring is between 5-10mm.Ensure the weight capacity of draining ring, can better work be realized to make this device.
The diameter of described contact blade is greater than draining ring interior diameter.Under guarantee draining ring realizes the prerequisite of drainage preferably, increase the diameter of contact blade to greatest extent, to reach the ability strengthening longitudinal magnetic field, improve the breaking capacity of arc control device further.
The width of described connecting lever is 1/2 of conducting rod diameter.Increase the width of connecting lever to greatest extent, to suppress eddy current, reach the breaking capacity better improving vacuum interrupter.
To sum up, the beneficial effects of the utility model are:
1, this contact blade is not at bottom slot, but arranges plate in bottom, inserts in the respective slot on iron core, adds the thickness of contact blade, and the intensity of contact blade is strengthened, and avoids contact blade to occur the situation of fracture.
2, multiple iron plate is set on iron core, the bottom of multiple iron plate is structure as a whole, convenient processing and process, reduce difficulty of processing, cost is low, and the gap formed between multiple iron plate is to stop the flowing of eddy current to reduce eddy current, shortens the time that longitudinal magnetic field lags behind electric current in circuit, reduce vacuum interrupter arc voltage, further increase the breaking capacity of vacuum interrupter.
3, the thickness range of every sheet iron plate is between 1-2mm.To increase the quantity of the iron plate on iron core to greatest extent, to form more gap, reach and better stop vortex flow, reduce eddy current.
