One protective cover (40), be fixedly attached outside case for circuit breaker (10) and cover connects indicating dial (30), and this protective cover (40) is established at least one inside and outside inspection hole (41), this through hole (41) and Status Flag (32) adaptation that run through.
Among one embodiment, this outer convex surface (31) is spherical interior surface.
Among one embodiment, this Status Flag (32) is divided into spaced apart combined floodgate sign and separating brake sign.
Among one embodiment, this combined floodgate sign and separating brake sign arrange different colours.
Among one embodiment, this Status Flag (32) group number is at least two groups, and this at least two groups Status Flag (32) circumferentially interval is arranged; The group number of this inspection hole (41) number and Status Flag (32) equates and circumferential interval is arranged.
Among one embodiment, this protective cover (40) comprises that the cover section (42) and of an adaptive outer convex surface (31) is by cover section (42) the outward extending fixedly periphery of periphery (43), fixedly periphery (43) is fixedly attached outside case for circuit breaker (10), and this cover section (42) cover connects indicating dial (30).
Among one embodiment, this indicating dial (30) also has that a ，Gai plane, plane is arranged dorsad with outer convex surface (31) and periphery is connected, and this mounting rod (33) vertically is fixed in planar central.
Among one embodiment, this mounting rod (33) end is established screw thread, separately by stop nut (50) connection bar (33) and rotating shaft (20).
The technical program is compared with background technology, and it has following advantage:
1. Status Flag is located at the outer convex surface of indicating dial; and protect indicating dial by protective cover; avoided in transportation, by scratching, caused pointer to relatively rotate in the installment and debugging process or the situation of the misregister such as crooked occurs, can in polarizers of big angle scope more, be observed circuit breaker minute, "on" position.
2. appearance looks elegant, top grade.
3, protective cover comprises cover section and fixing periphery, and fixedly periphery is fixedly attached outside case for circuit breaker, and cover section cover connects indicating dial, easy for installation fast.
The accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 has illustrated the perspective exploded view of circuit breaker opening and closing state indicating device;
Fig. 2 has illustrated the schematic perspective view of indicating dial.
Embodiment
Please refer to Fig. 1 to Fig. 2, a kind of circuit-breaker switching on-off state indicating device, it is connected to case for circuit breaker 10 and drives in the rotating shaft 20 of insulated tension pole 21, and this indicating device comprises an indicating dial 30 and a protective cover 40.
Described indicating dial 30, have that an outer convex surface 31 is arranged with outer convex surface 31 dorsad with a ，Gai plane, plane and periphery is connected; Should be spherical interior surface by outer convex surface 31, on this outer convex surface 31, establish at least one group of Status Flag 32; This indicating dial 30 is connected with mounting rod 33, and this mounting rod 33 vertically is fixed in planar central.This mounting rod 33 synchronously is rotationally connected from outer putting in toward in case for circuit breaker 10 and with rotating shaft 20; Among the present embodiment, these mounting rod 33 ends are established screw thread, separately by stop nut 50 connection bars 33 and rotating shaft 20.The indicating dial of convex surface design, more in polarizers of big angle scope, observed circuit breaker minute, "on" position.
Described protective cover 40, be fixedly attached outside case for circuit breaker 10 and cover and connect indicating dial 30, this protective cover 40 is established at least one inside and outside inspection hole 41 that runs through, this through hole 41 and Status Flag 32 adaptations, described Status Flag 32 is divided into spaced apart combined floodgate sign and separating brake sign, this combined floodgate sign and separating brake sign arrange different colours, in order to intuitively check the state of circuit breaker, and outward appearance is more attractive in appearance, high-grade.
