When preferred described overhead gage 1, described lower baffle plate 2 are all in level, the lower end of described overhead gage 1 and the upper part of described lower baffle plate 2 are stacked, very close to each other between such overhead gage 1 and lower baffle plate 2, can reliably close.
Described the first side wall 3 is also provided with the side plate 27 be oppositely arranged with described the first side wall, described transmission mechanism is between described the first side wall 3 and described side plate 27, the setting of side plate 27 can block transmission mechanism, not only more attractive in appearance, and can isolate transmission mechanism.
The manual operation section of described rotation operating-controlling mechanism is arranged at outside circuit breaker compartment, when circuit breaker needs when overhauling position maintenance, operating personnel are without the need to entering circuit breaker compartment, overhead gage 1, the closing of lower baffle plate 2 can be operated outward at circuit breaker compartment, enter the equipment such as compartment maintenance position maintenance circuit breaker after isolated high-voltage again, the personal safety of operator can be ensured.
Between the net barrier between different electric substations or between the different net barriers of same electric substation, size can build up same depth different in width as required.The shielded area of overhead gage 1, lower baffle plate 2 will change with the different in width between net barrier; But the version of net grid is basically identical, overhead gage 1, lower baffle plate 2 mounting means are also fixing.
Feature accordingly, makes fixed mode the Basic Design of isolating door device, and overhead gage 1, lower baffle plate 2 is prefabricated in advance, does simple fixing as long as on-the-spot.Can implement easily and efficiently like this to install.For the net grid of different in width, if change when prefabricated overhead gage 1, lower baffle plate 2 height just passable, its adaptability can be improved so again.
The course of work of the isolating door device in circuit breaker of the present invention:
As shown in Figure 1, isolating door closing process, rotate crank 22, crank 22 is by drive link assembly, rotation is exported to the first sprocket wheel 7, the first sprocket wheel 7 is driven to rotate, first sprocket wheel 7 is rotated through the first chain 10, rotation is driven to the second sprocket wheel 8, rotation is driven to three sprocket wheel 11 coaxial with the second sprocket wheel 8 by the second sprocket wheel 8 again, rotation is driven to the 4th sprocket wheel 12 by the second chain 15 by the 3rd sprocket wheel 11 on the one hand, thus drives lower baffle plate 2 counterclockwise to turn to horizontal level around the second rotating shaft 6; Drive on the first gear 16 coaxial with the 5th sprocket wheel 13 by the 5th sprocket wheel 13 on the other hand simultaneously, first gear 16 and the second gear 17 engaged transmission, rotation is driven to the 7th sprocket wheel 20 by the 3rd chain 21 by the second gear 17, thus drive overhead gage 1 to turn to horizontal level around the first rotating shaft 5 clockwise direction, isolating door is closed, then locks closed condition by positioner.
As shown in Figure 2, isolating door opening process: opposite spin crank 22, crank 22 is by drive link assembly, rotation is exported to the first sprocket wheel 7, the first sprocket wheel 7 is driven to rotate, first sprocket wheel 7 is rotated through the first chain 10, rotation is driven to the second sprocket wheel 8, rotation is driven to three sprocket wheel 11 coaxial with the second sprocket wheel 8 by the second sprocket wheel 8 again, rotation is driven to the 4th sprocket wheel 12 by the second chain 15 by the 3rd sprocket wheel 11 on the one hand, thus drives lower baffle plate 2 to turn to vertical position around the second rotating shaft 6 clockwise direction; Drive on the first gear 16 coaxial with the 5th sprocket wheel 13 by the 5th sprocket wheel 13 on the other hand simultaneously, first gear 16 and the second gear 17 engaged transmission, rotation is driven to the 7th sprocket wheel 20 by the 3rd chain 21 by the second gear 17, thus drive overhead gage 1 counterclockwise to turn to vertical position around the first rotating shaft 5, isolating door is opened, then locks opening by positioner.
Obviously, above-described embodiment is only for clearly example being described, and the restriction not to execution mode.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all execution modes.And thus the apparent change of extending out or variation be still among the protection range of the invention.
