The permanent magnet pulse electric operating mechanism of the urgent switching-off device of described band is characterized in that rotating the connection of thrust magnet steel turning handle is set.
The permanent magnet pulse electric operating mechanism of the urgent switching-off device of described band is characterized in that rotating thrust magnet steel, slope thrust magnet steel two and magnetic conduction fixed head, magnetic conduction fixed glides is set the outside respectively relatively.
The permanent magnet pulse electric operating mechanism of the urgent switching-off device of described band is characterized in that rotating the thrust magnet steel and is rotatably assorted by turning set and separating brake housing, and the slope thrust magnet steel is slidingly matched by slip ring and separating brake housing.
The permanent magnet pulse electric operating mechanism of the urgent switching-off device of described band is characterized in that rotating being provided with respectively between thrust magnet steel, slope thrust magnet steel two semicircles and changes beam, sliding Gu Liang.
The permanent magnet pulse electric operating mechanism of the urgent switching-off device of described band is characterized in that the slope thrust magnet steel fixedlys connected with main shaft by hold-down screw.
The permanent magnet pulse electric operating mechanism of the urgent switching-off device of above-mentioned band is skillfully constructed, and is simple in structure, and the operation flexible operation is convenient, and production cost is low, and is easy to maintenance, reduced the electric energy consumption of transmission line equipment of itself.Do not having to realize the manual emergency separating brake by urgent switching-off device under the situation of power supply, opening velocity is fast, and the vacuum extinction performance is good, and circuit devcie is difficult for causing damage, and causes interference little, safe in utilization, reliable to telemetry circuit simultaneously.
Description of drawings
Fig. 1 is the structural representation with the permanent magnet pulse electric operating mechanism of urgent switching-off device; Fig. 2 is for rotating the structural representation of thrust magnet steel; Fig. 3 is the structural representation of slope thrust magnet steel.
Embodiment
As shown in the figure, the corresponding layout between coil 5, two coils 5 is provided with magnet steel 4 in housing 6 inner chamber both sides, and magnet steel 4 is the continuous annular structure, also can be bar shaped circulus at interval.The connecting shaft magnetic core slide block 20 that connects main shaft 1 passes coil 5, magnet steel 4 centers, and main shaft 1 two ends are slidingly matched by oiliness bearing 7 and end cap 2, connection cover 19.End cap 2, connection cover 19 are fixedlyed connected by screw 3 with housing 6.Separating brake housing 8 is fixedlyed connected with connection cover 19 by screw 3, be provided with in separating brake housing 8 chambeies and rotate thrust magnet steel 11, slope thrust magnet steel 17, rotation thrust magnet steel 11, slope thrust magnet steel 17 are made of two semicircle magnet steel respectively, adopt Nd-Fe-Bo permanent magnet material, its two opposite outer is provided with respectively to be provided with respectively between magnetic conduction fixed head 9, magnetic conduction fixed glides 15, the two semicircle magnet steel changes beam 12, sliding solid beam 16.Rotate thrust magnet steel 11 outer rims turning set 10 is set, be rotatably assorted by turning set 10 and separating brake housing 8 inner chambers, and connection is provided with turning handle 18.Turning handle 18 can rotate between the 0-90 degree.Slope thrust magnet steel 17 is slidingly matched by slip ring 14 and separating brake housing 8 inwalls, and fixedlys connected slip ring 14 outer rims, separating brake housing 8 inwall relative set raised lines and groove or groove and raised line with main shaft 1 end by hold-down screw 13.The present invention only relates to the technical scheme with the motor-operating mechanism of urgent switching-off device, and other parts, the equipment that are mated are general known technology, do not repeat them here.
