Embodiment
Below more in conjunction with the accompanying drawings example the utility model is described in further detail.
Basis three station earthing isolator operating means shown in Figure 1, there is one by device frame 14, the frame that supporting bracket 23 and fixed head 22 constitute, between device frame 14 and fixed head 22, driving shaft 15 is housed by bearing, driving shaft 15 is equipped with worm gear 21 and dial 3 by flat key 16, worm gear 21 and one is used for worm screw 13 engagements of input operation power, dial 3 be provided with drive block and finger 2 is housed and finger 4(finger 4 as shown in Figure 2), finger 2 and finger 4 are symmetrically distributed with respect to the active axis hole on the dial 3; Also by bearing jack shaft 17 is housed between device frame 14 and fixed head 22, jack shaft 17 is equipped with sheave 1 and driving gear 5 by flat key 18, sheave 1 be provided with dial 3 on the drive block engagement teeth groove and with the corresponding cotter way of finger 2,4 on the dial 3; Between two device framves 14, the driving shaft 19 of spline structure is housed by bearing, driven gear 6 is housed on the driving shaft 19, driven gear 6 and driving gear 5 engagements that are contained on the jack shaft 17, also be equipped with on the driving shaft 19 3 groups by slurcam 7 on drive rod 11 on the link stopper 12, the actuating arm that constitutes of link stopper 9 and following drive rod 10 down
FromMoving gear 6 and respectively organize between the actuating arm by axle sleeve 20 and other axle sleeve and locate; Each group actuating arm has two slurcams 7, last link stopper 12 is contained in the slotted eye of two slurcams 7 by the axle of its both sides, following link stopper 9 is contained in the slotted eye of two slurcams 7 by the axle of its both sides, last link stopper 12 and following link stopper 9 are separately positioned on the upper and lower position of driving shaft 19, on last link stopper 12, be connected with drive rod 11, be connected with drive rod down on the link stopper 9 down
10(as figure
5Shown in), last drive rod 11 is used for arc control device 25 drivingly, and following drive rod 9 is used for drive isolating arc control device 24, as Fig. 2-shown in Figure 5.
Fig. 2 is dial 3 of the present utility model and sheave 1 local part planar structure schematic diagram, and finger 2 and finger 4 are fixed on the dial 3, can rotate freely around its center separately; Dial 3 drives sheave 1 by finger 2 on the dial 3 or finger 4 and rotates; When finger 2 or finger 4 do not enter the cotter way that radially is provided with of sheave 1, because the indent circular arc teeth groove of sheave 1 pinned by the drive block of the evagination circular arc on the dial 3, so sheave 1 transfixion; When finger 2 or finger 4 enter sheave
1The cotter way that radially is provided with the time, the locking arc unclamps, finger 2 or finger 4 drive sheaves 1 and rotate.
Fig. 3 is the structural representation of the utility model when mediating, and at this state, earthed switch and isolating switch all are in the separating brake position, 9 pairs of isolation usefulness of block
DownDrive rod 10 does not produce active force, and block 12 is not also to earthy
OnDrive rod 11 produces active force; All be in gate-dividing state so connect isolation arc control device 24 with ground arc control device 25.When finger 2 or finger 4 did not enter the radial slot of sheave 1, worm screw 13 belonged to idle running.
Fig. 4 is the structural representation of the utility model when being in earthing position; When the centre position, be rotated counterclockwise worm screw 13, thereby drive the rotation of turbine 21, enter the cotter way that radially is provided with of sheave 1 until finger 4, sheave 1 and driving gear 5 shared one, driving gear 5 drives driven gears 6 rotations; Driven gear 6 and slurcam 7 are fixed on the driving shaft 19, and along with the rotation of driven gear 6, slurcam 7 promotes the motion of block 12, and block 12 drives earthy
OnDrive rod 11 motions; When finger 4 skids off the cotter way that radially is provided with of sheave 1,
OnDrive rod 11 drives ground connection arc control device 25 and closes a floodgate, and earthed switch is connected; Simultaneously, because the effect of slotted hole 8 on the slurcam 7, slurcam 7 so isolate the effect that arc control device 24 do not stress, still is off-state not to block 9 generation power; When continuing to be rotated counterclockwise worm screw 13, sheave 1 is static, still is held at ground state; At this moment, the worm screw 13 that turns clockwise can make transmission device get back to the centre position.
Accompanying drawing 5 is the utility model structural representations when being in the isolated location; When the centre position, the worm screw 13 that turns clockwise, the principle of connecting with earthed switch is the same, can make to isolate arc control device 24 combined floodgate connections; Different is to be that block 9 drives at this moment
DownDrive rod 10 moves and realizes isolating the connection of arc control device 24, and block 7 is not right
Last drivingThe effect that bar 11 produces power.
