Embodiment
Below by embodiment, technical scheme of the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of duplicate supply high-pressure vacuum breaker, it comprise Shell of circuit breaker 1, three groups of leading-out terminals 2, three groups of rotation arc control device 3, three groups isolate that earth terminal, end of incoming cables, three groups of I roads, end of incoming cables, three groups of II roads, divide-shut brake device, divide-shut brake output drive connecting lever 15, divide-shut brake catch bar 4, are sleeved on tripping spring 5 on the divide-shut brake catch bar 4, linkage structure, straight line transmission coupling 11, locking drive link 12, motor and motor-driven rotating disk 13 without spin;
Wherein, described divide-shut brake output drives connecting lever 15 1 ends and is installed on the output shaft 14 of described divide-shut brake device, described divide-shut brake device drives described divide-shut brake output driving connecting lever 15 and rotates in the counterclockwise direction, drives described divide-shut brake catch bar 4 so that the output of described divide-shut brake drives connecting lever 15;
The moved end pull bar 6 of described rotation arc control device 3 connects described divide-shut brake catch bar 4 by linkage structure, and promptly described divide-shut brake catch bar 4 drives the moved end pull bar 6 of described rotation arc control device 3, so that make circuit breaker carry out breaking-closing operating;
Described linkage structure comprises connection connecting lever 7, insulated tension pole 8, touch spring 9 and connecting lever 10, wherein, connect connecting lever 7 one ends and connect moved end pull bar 6, its other end connects insulated tension pole 8, insulated tension pole 8 connects touch spring 9, touch spring 9 connects connecting lever 10 1 ends, and connecting lever 10 other ends connect divide-shut brake catch bar 4, connects connecting lever 7 and connecting lever 10 middle parts and fixes;
Described rotating disk 13 is connected with the swivel mount of described rotation arc control device 3, and promptly described rotating disk 13 can drive described rotation arc control device 3 and rotatablely move synchronously;
Described rotating disk 13 is provided with the center that is provided with rotation hole, 17, three positions, road 16 and rotation road 17 between the hole, 16, three positions, hole, three positions 16 and all is positioned on the concentric circles of described rotating disk 13, and described locking drive link 12 is located in the institute rheme hole 16; When the described rotation arc control device 3 of rotating disk 13 drives rotatablely moved synchronously, described locking drive link 12 can move in hole, three positions 16 and rotation road 17;
The diameter of described locking drive link 12 the inners is less than the width in described rotation road 17, and the diameter of described locking drive link 12 outer ends is greater than the width in described rotation road 17; It is in order to realize blocking function that this size limits, promptly when described locking drive link 12 the inners are located in the institute rheme hole 16, described locking drive link 12 can and rotate free movement between the road 17 in hole, three positions 16, when described locking drive link 12 outer ends were located in the institute rheme hole 16, described locking drive link 12 was limited in the hole, three positions 16; Furtherly, in case close a floodgate, described locking drive link 12 travels forward, and described locking drive link 12 outer ends are located in the institute rheme hole 16, and then rotating disk 13 can't rotate again;
