Below in conjunction with above-mentioned accompanying drawing preferred embodiment of the present utility model is specified.
Energy storage device of the present utility model is made up of electronic and manual two parts, and as shown in Figure 1, they transmit operating physical force with motor 3 and handle 4 respectively.As Fig. 2, shown in Figure 3, the shared same power transmission shaft 8 of their transmission mechanism, axle 8 pass the axle sleeve 54 that is welded on the riser 2 and are horizontal rotary arm, and in the left side of riser 2, handle 4 is enclosed within on the square spigot of axle 8 fastening by nut and pad.On the right side of riser 2, torsion spring 9 is enclosed within on the axle sleeve 54.Electronic connecting lever 12 can be selected two kinds of schemes for use with the structural relation of axle 8.As shown in Figure 4, connecting lever 12 is welded on the axle sleeve 53, and axle sleeve 53 can rotate on axle 8.As shown in Figure 5, axle has a boss on 8, and connecting lever 12 is enclosed within on the axle 8 between boss and axle sleeve 54 sides.Torsion spring 10 is enclosed within on the boss of axle sleeve 53 or axle 8.Manually connecting lever 7 is welded in axle 8 right-hand members, near the side of axle sleeve 53 or boss.Shown in Fig. 3,4,5, connecting lever 7 lower ends are welded with pin 6.As shown in Figure 3, roller 13 and connecting lever 12 lower ends are clipped between the connecting plate 15,16 by pin 14 cross-under together, and connecting lever 12 leans against on the pin 6.Be enclosed within on the axle 8 for the axle sleeve 54 of one owing to connecting lever 12 or with connecting lever 12 welderings, they are movingly, under torsion spring 10 restoring force effects, when connecting lever 12 swings, axle 8 does not move, and therefore, does not also move with the handle 4 that is connected with axle 8 square spigots with the connecting lever 7 that axle 8 is welded as a whole.
Closing device after the improvement as shown in Figure 6, the screw rod 42 that the end has a boss passes the hole of connecting plate 43 and mounting panel 41 and electromagnet base plate, is spirally connected respectively with the moving iron core 47 and the connector 48 of making electromagnet 46, and is fastening with nut, pad.Connector 48 links together by pin 49 and fork-shaped keeper 50.Hole and connecting plate 43 that draw ring 45 passes flat board 1 are spirally connected; Fastening under spring 44 tension force effects.Because screw rod 42 adopts with connector 48 and is spirally connected, their effective length is adjustable, and therefore, the deflection angle of keeper 50 is adjustable.As shown in Figure 1, the axis of screw rod draws close combined floodgate, switching-off device between the axle center vertical line of three-phase main shaft 25 and energy storage axle 21, helps the operating mechanism compact overall structure.
Operation is described below, referring to accompanying drawing 1.
When circuit breaker at separating brake not during the energy storage state, give energy storage motor 3 energized, the eccentric wheel of driven by motor on it rotates, and drives connecting levers 12 and connecting plate 15,16 swings by aiming near eccentric roller 13, thereby promote 23 swings of energy storage ratchet, energy storage ratchet 23 promotes ratchet and rotates.Ratchet separates with energy storage axle sleeve 22, therefore motor only drives ratchet idle running when energy storage begins, after the plate that forwards pin on the ratchet and energy storage axle sleeve to was close to, ratchet drove the energy storage axle sleeve and moves together, thereby the switching-in spring 36 that hangs on the energy storage axle sleeve is elongated.After in switching-in spring 36 is crossed, the energy storage axle sleeve is fixed by keeper 50, and the energy storage state of switching-in spring is maintained, and energy storage finished to this moment.Switching-in spring excessively in, connecting lever on the energy storage axle sleeve promotes travel switch 20 and cuts off the energy storage motor power supplys, and the energy storage ratchet is lifted, and energy storage ratchet and ratchet is reliably broken away from, thereby realize electric energy-stored.
When carrying out manual energy storage, can spur energy storage handle 4, drive connecting lever 7 and promote connecting lever 12 and connecting plate 15,16 swings, make the energy storage ratchet promote ratchet and rotate and realize manual energy storage by the pin on it 6.
Mechanism receives after the switching signal, and the iron core 47 of making electromagnet 46 is attracted to down motion, rotates to counter-clockwise direction by screw rod 42 pulling keepers 50, breaks away from the energy storage axle sleeve, removes energy storage and keeps.Switching-in spring releases energy and drives the rotation of energy storage axle sleeve counter-clockwise direction, cam on the energy storage axle sleeve presses the roller 24 on the three-phase main shaft sleeve 26, the main shaft sleeve clockwise direction is rotated, drive rocking arm 28 and three-phase main shaft 25 motions that are connected with the main shaft sleeve key, fasten semiaxis 31 up to rocking arm 28, then mechanism is in "on" position, finishes the electric switch-on operation.When mechanism was in "on" position, interlock lock in place part can not rotate keeper to counter-clockwise direction, made mechanism can not realize closing a floodgate again, reached air defense and closed the interlocking purpose.
When pulling moving draw ring 45, keeper 50 rotates to counter-clockwise direction, removes energy storage and keeps, and repeats the above-mentioned spring process that releases energy, and realizes the closing by hand operation.
The energy-stored spring energy of mechanism is finished feed motion after discharging.In "on" position, mechanism can carry out stored energy operation again, finish stored energy operation after, mechanism is in the energy storage state that closes a floodgate, and when this state, in case need, can realize single shot reclosing.
Behind the breaker closing, in case tripping electromagnet is received signal, tripping electromagnet 38 adhesives, release jack-up button axle 32 rotates, and drives push rod 29 and moves upward, and pushes bent plate 30 and drives semiaxis 31 and rotate to counter-clockwise direction, when semiaxis forwards certain position to, semiaxis and rocking arm 28 are triped, and under the effect of tripping spring, circuit breaker is finished sub-switching operation.
When with pulling when starting separating brake draw ring 40, bent plate 30 drives semiaxis 31 and rotates to counter-clockwise direction, and semiaxis and rocking arm 28 are triped breaker open operation.
When overcurrent release overcurrent, the overcurrent release action, release pushes trip shaft 32, makes push rod 29 push bent plate 30, and semiaxis 31 is triped with rocking arm 28, and circuit breaker is finished overcurrent dropout operation.
