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, separating brake sincere sub 16 and the sincere sub-axle 17 of 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 the latch mechanism 3 and transmission mechanism that are controlled by key 31, switch 2 is provided with in described circuit, in the present embodiment, switch 2 is sensitive switch, this switch 2 is for controlling the switch of the circuit of electric blocking, when latch mechanism 3 opened by key 31, described key 31 can not be pulled up from latch mechanism 3, latch mechanism 3 makes switch 2 be in closure state, but to combined floodgate bent plate 18, separating brake sincere sub 16 and the sincere sub-axle 17 of separating brake 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 be in off-state, and by transmission mechanism, separating brake sincere sub 16 and the sincere sub-axle 17 of separating brake are threaded off and separating brake, make combined floodgate bent plate 18 to close a floodgate simultaneously.
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, can reset again between them, described combined floodgate bent plate 18 is located at through the rotating shaft 19 in the middle part of it, is provided with the slotted eye stretched 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 maintains 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 do various change with separating brake sincere sub 16 and combined floodgate bent plate 18 on shape, position.
Described first transmission mechanism is the separating brake bent plate 5 of L shape, described 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, second guide plate 14, fairlead 15, separating brake bent plate 5 and the corresponding described top guide bar 32 of left guide rod 7 are located at above latch mechanism 3, when top guide bar 32 up moves, separating brake bent plate 5 is driven to rotate, separating brake bent plate 5 is fixedly connected on the sincere sub-axle 17 of separating brake and the sincere sub-axle 17 of separating brake can be driven to rotate, the sincere sub-axle 17 of separating brake is thrown off with separating brake sincere sub 16, the stage clip 8 for resetting is provided with between left guide rod 7 and shell 1, left guide rod 7 is through the first guide plate 6 and shell 1 and be connected to connecting plate 13, connecting plate 13 is fixedly connected on again one end of lever 9, lever 9 is rotated by pin 10 and is installed on fixed head 11, 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 through fairlead 15 and the second guide plate 14 and make it turn to combined floodgate.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, top guide bar 32 and lower guide rod 33 is driven all to move down, connect for closed when the corresponding lower guide rod 33 of described switch 2 to be located at below latch mechanism 3 and to press its switch, the pressing of lower guide rod 33 makes switch 2 close, and the normally closed point of sensitive switch is received inside closing circuit of circuit breaker.Not to transmission mechanism effect when top guide bar 32 moves down, both do not acted on the sincere sub-axle 17 of separating brake and the sincere son of separating brake, also do not act 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, when closing blocking mechanism 3, top guide bar 32 and lower guide rod 33 is driven all up to move, lower guide rod 33 leaves switch 2, and switch 2 disconnects, the effect that top guide bar 32 moves, the sincere sub-axle 17 of separating brake is thrown off with separating brake sincere sub 16, and make combined floodgate bent plate 18 to turn to combined floodgate simultaneously, now key 31 can be pulled up, and has administrative staff to preserve, until confirm that fault is got rid of, just with key 31, circuit breaker is again closed a floodgate by administrative staff.Reach the object entirely stably controlling circuit breaker, achieve circuit breaker electric blocking and circuit-breaker switching on-off function safely and reliably.
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, achieve electric blocking and deciliter function safely and reliably.
Indoor high-voltage vacuum circuit breaker procedure lock linkage of the present invention is a kind of mechanical lock device of series high voltage switchgear.Personnel are according to set safe handling procedures in this procedure lock linkage forced service, operate, thus avoid the misoperation of electric equipment to indoor high-voltage vacuum circuit breaker, reach " five prevent " requirement that former Ministry of Water Resources and Power Industry proposes perfectly.
Of the present inventionly be not limited to above embodiment and conversion.
