Embodiment
Below in conjunction with accompanying drawing, a kind of indoor high-voltage vacuum circuit breaker of the present invention is described further.
As Fig. 1, Fig. 2, shown in Fig. 3, the indoor high-voltage vacuum circuit breaker of the present embodiment, comprise shell 1, combined floodgate bent plate 18, the sincere sub-axle 17 of separating brake sincere sub 16 and separating brake, also comprise and control combined floodgate bent plate 18, the circuit of separating brake sincere sub 16 and the sincere sub-axle 17 of separating brake, described circuit breaker is also provided with latch mechanism 3 and the transmission mechanism of being controlled by key 31, in described circuit, be provided with switch 2, in the present embodiment, switch 2 is sensitive switch, this switch 2 is for controlling the switch of the circuit of electric blocking, when key 31 is opened latch mechanism 3, described key 31 can not be pulled up from latch mechanism 3, latch mechanism 3 makes switch 2 in closure state, but to combined floodgate bent plate 18, the sincere sub-axle 17 of separating brake sincere sub 16 and separating brake is inoperative, when key 31 closes blocking mechanism 3, described key 31 can be pulled up from latch mechanism 3, latch mechanism 3 makes switch 2 in off-state, and by transmission mechanism, the sincere sub-axle 17 of separating brake sincere sub 16 and separating brake is threaded off and separating brake, the bent plate 18 that simultaneously makes to close a floodgate cannot close a floodgate.
The corresponding separating brake of the sincere sub-axle 17 of described columniform separating brake sincere sub 16 is provided with a breach, when the sincere sub-axle 17 of separating brake rotates, the sincere sub-axle 17 of separating brake is thrown off with separating brake sincere sub 16, under the effect of torsion spring, between them, can reset again, described combined floodgate bent plate 18 is located at the rotating shaft 19 through its middle part, is provided with the slotted eye stretching into for described lock piece 12 between combined floodgate bent plate 18 and rotating shaft 19.Because the sincere sub-axle 17 of separating brake in the present embodiment has kept existing structure with the structure of separating brake sincere sub 16 and combined floodgate bent plate 18, known for the skilled in the art, so do not do too much description.The sincere sub-axle 17 of certain above-described separating brake can be done various variations with separating brake sincere sub 16 and combined floodgate bent plate 18 on shape, position.
Described the first transmission mechanism is L shaped separating brake bent plate 5, described the second transmission mechanism comprises the first guide plate 6, left guide rod 7, stage clip 8, be located at the lever 9 of shell 1, lock piece 12, the second guide plate 14, fairlead 15, the corresponding described top guide bar 32 of separating brake bent plate 5 and left guide rod 7 is located at latch mechanism 3 tops, when top guide bar 32 up moves, drive separating brake bent plate 5 to rotate, separating brake bent plate 5 is fixedly connected on the sincere sub-axle 17 of separating brake and can drives the sincere sub-axle 17 of separating brake to rotate, the sincere sub-axle 17 of separating brake and separating brake sincere sub 16 are thrown off, between left guide rod 7 and shell 1, be provided with the stage clip 8 for resetting, left guide rod 7 is through the first guide plate 6 and shell 1 and be connected in connecting plate 13, connecting plate 13 is fixedly connected on again one end of lever 9, lever 9 is rotated and is installed on fixed head 11 by pin 10, fixed head 11 is fixed on shell 1, the other end of lever 9 is connected with lock piece 12, lock piece 12 also can stretch in combined floodgate bent plate 18 and make it cannot turn to combined floodgate through fairlead 15 and the second guide plate 14.Certain above-described rotating mechanism, common Machine Design personnel can make countless versions conversion, and described switch 2 also can be transformed to other switches in addition, and these conversion all belong to equivalent structure.
As shown in Figure 4, Figure 5, described latch mechanism 3 is provided with top guide bar 32 and lower guide rod 33, when key 31 rotating opening latch mechanism 3, drive top guide bar 32 and lower guide rod 33 all to move down, when being located at latch mechanism 3 belows and pressing its switch, connects for closed the corresponding lower guide rod 33 of described switch 2, pressing of lower guide rod 33 makes switch 2 closures, and the normally closed point of sensitive switch is received closing circuit of circuit breaker the inside.When top guide bar 32 moves down not to transmission mechanism effect, both do not acted on the sincere sub-axle 17 of separating brake and the sincere son of separating brake, and also do not acted on combined floodgate bent plate 18, now circuit breaker is free to the divide-shut brake of manual and electric, be equivalent to the circuit breaker before improving, now cannot pull up key 31.As shown in Figure 6, Figure 7, when key 31 rotates 180 degree, while closing blocking mechanism 3, drive top guide bar 32 and lower guide rod 33 all up to move, lower guide rod 33 leaves switch 2, and switch 2 disconnects, the effect moving on top guide bar 32, the sincere sub-axle 17 of separating brake and separating brake sincere sub 16 are thrown off, and the bent plate 18 that makes to close a floodgate cannot turn to combined floodgate simultaneously, now key 31 can be pulled up, and has administrative staff to preserve, until confirm fault eliminating, just by administrative staff, with key 31, circuit breaker is closed a floodgate again.Reached and entirely stably controlled the object of circuit breaker, realized safely and reliably circuit breaker electric blocking and circuit-breaker switching on-off function.
In addition, the indoor high-voltage vacuum circuit breaker procedure lock linkage of the present embodiment can fill the various control functions such as lock one key, two lock one keys, three lock two keys.
The indoor high-voltage vacuum circuit breaker of the present embodiment is the spring operating mechanism of floor plan, compact conformation, between each parts, gap is little, so procedure lock linkage is contained in spring operating mechanism, structure is more compact, and precision is high, and installation site is ingenious, adopt the version of three linkages, realized safely and reliably electric blocking and deciliter function.
Indoor high-voltage vacuum circuit breaker procedure lock linkage of the present invention is the mechanical lock device that a kind of series high voltage switchgear is used.Personnel are according to set safety operation program in this procedure lock linkage forced service, indoor high-voltage vacuum circuit breaker is operated, thereby avoided the misoperation of electric equipment, reach " five is anti-" requirement that Liao Yuan Ministry of Water Resources and Power Industry proposes perfectly.
Of the present inventionly be not limited to above embodiment and conversion.
