Fig. 1 represents the three-position type switch operating mechanism, and it comprises the step-by-step switch operating mechanism SSG as important component part.Driven lever ABH, base plate GRP on the major part that belongs to step-by-step switch operating mechanism SSG has driven shaft ABW and is fixed on driven shaft ABW and figure go up invisible guide groove, the switch slide plate SSC that has its switch chute SKU and two drive pin MB1, MB2, circuit breaker manipulation axle BWT fixedlys connected with earth connection control lever shaft BWE and with circuit breaker manipulation axle BWT and has a drive plate ANS (Fig. 2 to 7) that two leads untie-sell TZ1, TZ2.Expression driven shaft ABW can handle to two direction of rotation DRW among the figure, and wherein direction of rotation of separate provision is used for circuit breaker effect T, and opposite direction of rotation is used for earth connection effect E.As seen from the figure, two control lever shafts that is circuit breaker manipulation axle BWT and earth connection control lever shaft BWE guide by the block bearing that not have expression among the figure at the left part of figure, so that can manually rotate by corresponding actuating mechanisms from front end.Visible in addition this three-position type switch operating mechanism is provided with a lock shaft VRW, and it acts on check lock lever VRH and the fork KHB by its lateral pin.Shutter BLV can be by lock shaft VRW control, and the task of shutter BLV is to seal or discharge the actuation holes of circuit breaker and earth connection as requested.Circuit breaker indication axle AWT and earth connection indication axle AWE have also been represented among the figure, they are that circuit breaker pointer ZGT is connected with earth connection pointer ZGE with corresponding pointer, and handle by cam disc KVS jointly by means of circuit breaker control lever SHT/ earth connection control lever SHE respectively.As the back also will be introduced, circuit breaker indication axle AWT and earth connection indication axle AWE connect into corresponding pivoted lever ULT, ULE, can handle circuit breaker control lever SHT/ earth connection control lever SHE, be used to handle relevant rotatablely moving of AWE of circuit breaker indication axle AWT/ earth connection indication axle along one and do lateral deflection.For the ease of understanding, mainly represented the movable part of three-position type switch operating mechanism among the figure, removed from the band block bearing the structural design of shell.Can find out that in addition in order to understand each course of work, Fig. 1 has stipulated cutting plane A-A, B-B and C-C have represented these courses of work below among Fig. 2 to 15.
One by one describe the motion process of step-by-step switch operating mechanism among Fig. 2 to 7 below in detail.Fig. 2 along cutting plane A-A has represented that they act on the public drive plate ANS by the circuit breaker manipulation axle BWT and the earth connection control lever shaft BWE of gear connection.But the switch slide plate SSC of horizontal-shift is in drive plate ANS back, and it passes base plate GRP by two drive pin MB1, MB2 and goes up not having in the detailed groove of representing of relevant groove FN1, FN2 insertion driven lever ABH.As seen from Figure 1, driven lever ABH is fixedlyed connected with driven shaft ABW, and by having the orientation rotation of the fixedly corner of predesignating, implements by rotatablely moving that circuit breaker manipulation axle BWT/ earth connection control lever shaft BWE causes.In addition as seen, switch slide plate SSC is provided with switch chute SKU, leads untie-sell TZ1, TZ2 and inserts among the switch chute SKU for two of drive plate ANS.
Fig. 2 to 5 represents each on off state, wherein, Fig. 2 is by the position of the switch " disconnection " expression lock-out state, and Fig. 3 represents to leave locking area and the driven motion of beginning, Fig. 4 represents that driven motion finishes and begin locking, and last Fig. 5 represents to be in the position of the switch " connection " of locking state.Such as already mentioned, the input of circuit breaker manipulation axle BWT/ earth connection control lever shaft BWE rotatablely moves and passes to drive plate ANS.Drive plate ANS leads among the switch chute SKU that untie-sell TZ1, TZ2 be inserted in switch slide plate SSC, and switch slide plate SSC is transmitted one section definite distance by the horizontal movement HBG (Fig. 2) that represents among the figure.At the end of transmitting range, lead untie-sell TZ1, TZ2 and switch slide plate SSC is fixed on its position of the switch " connection " is in locking state (Fig. 5).Meanwhile, the first drive pin MB1 of switch slide plate SSC inserts in the driving profile of the driven lever ABH that does not have expression in the drawings, and drives driven shaft ABW (Fig. 1) corner DRW of rotation (Fig. 1) to the relevant terminal position.Therefore, the linear reciprocating motion of switch slide plate SSC changes rotatablely moving of driven shaft ABW into.In this case driven shaft ABW (Fig. 1) but plug-in mounting become, the first drive pin MB1 that maybe will be drawn in the top inserts among the driven lever ABH, the second drive pin MB2 that maybe will be drawn in the below inserts among the driven lever ABH.Take this measure, when the direction of operating of circuit breaker manipulation axle BWT/ earth connection control lever shaft BWE kept identical, driven shaft ABW can have different direction of rotation.In this respect can with Fig. 2 and 5 and Fig. 6 and 7 make comparisons.
The locking of Fig. 8 to 15 expression three-position type switch operating mechanism and the detailed details of its position of the switch indication.As the main member that is used for this function, be cam disc KVS and the relevant circuit breaker control lever SHT/ earth connection control lever SHE that has circuit breaker pilot pin FST/ earth connection pilot pin FSE separately shown in the figure of Fig. 8 and back; The corresponding circuit breaker control lever SHT/ earth connection control lever SHE that has its circuit breaker pivoted lever ULT/ earth connection pivoted lever ULE; And the circuit breaker indication axle AWT/ earth connection indication axle AWE and circuit breaker pointer ZGT/ earth connection pointer ZGE and the shutter BLV that are rotated by them at last.The locking of this inside prevents the misoperation of three-position type switch operating mechanism.In addition, position of the switch indication provides the on off state of three-position type switch operating mechanism by visible and electric mode.By the process of finishing the work that rotatablely moves of cam disc KVS, this rotatablely moves, corresponding to Fig. 8 to 11, and deflection circuit breaker control lever SHT/ earth connection control lever SHE and their circuit breaker pivoted lever ULT/ earth connection pivoted lever ULE separately.Relevant circuit breaker indicates axle AWT/ earth connection indication axle AWE that this is rotatablely moved, passes to the circuit breaker pointer ZGT/ earth connection pointer ZGE that indicates visibly on the signaling switch that is used for not having to represent here, to produce the switch position signal of an electricity.Shown in Figure 13 and 14, do not finishing between the distribution operational period, show that with circuit breaker pointer ZGT/ earth connection pointer ZGE the lines sign is not in level or plumbness, the expression abort situation.When not finishing the distribution operation, close the passage of going to that root control lever shaft that is helpless to finish the distribution operation by shutter BLV.For example in Figure 13 as can be seen, for " disconnection " transfers the position of the switch " connection " to from the position of the switch as embodiment is represented with circuit breaker manipulation axle BWT, as long as discharge circuit breaker manipulation mouth BTT.The release of circuit breaker manipulation mouth BTT/ earth connection actuation holes BTE separately depends on that the corresponding position of the switch of three-position type switch realizes.When the position of the switch of the three-position type switch of pressing Figure 12 " disconnection ", can or discharge circuit breaker manipulation mouth BTT, or discharge earth connection actuation holes BTE.Otherwise, if " connection " then can only discharge circuit breaker manipulation mouth BTT (Figure 15) in the position of the switch.These can be diverted to ground connection work equally.
For the three-position type switch can be coupled together with other switchgears in work by its different position of the switch, map interlinking 1 is provided with the shutter BLV that lock shaft VRW and shape are connected suitably, and check lock lever VRH and fork KHB.Wherein, check lock lever VRH is used for Stop-motion lock mandrel VRW, and fork KHB can control another electric output signal by its beat.Check lock lever VRH and fork KHB control or act on the lock shaft VRW by lateral pin QB1, the QB2 of lock shaft VRW.If check lock lever VRH is prevented from arriving dashdotted position, then rotatablely moving of lock shaft VRW prevented.Because shutter and lock shaft also shape are connected suitably, so shutter BLV also by stop, and thereby stops and discharges circuit breaker manipulation mouth BTT/ earth connection actuation holes BTE.In order to discharge one of circuit breaker manipulation mouth BTT/ earth connection actuation holes BTE, lock shaft VRW must or introduce earth connection work one and turn right or turn left according to desired distribution operation-introducing circuit breaker work.Take this measure, can reply different locking conditions for circuit breaker and earth connection.The rotatablely moving of lock shaft VRW can be used to be used for electricity and output signal machinery.In order to realize this working signal, be provided with lateral pin QB1, it causes fork KHB operation when lock shaft VRW rotates.This fork itself can be handled for example electric switch by its deflection by the mode that does not have expression among the figure, and thereby the electric output signal of control.In addition, for the different on off state of three-position type switch, check lock lever VRH can produce the output signal of machinery.
