When with breaker closing that interlocking modules 200 links to each other, interlocking process and the said process of interlock are similar, repeat no more.
Fig. 5 is the structural representation of driven member cable end of the present invention, has shown a kind of connected mode of cable 26 with driven member 40.The cable 26 that picks out from the driving link of an interlocking modules, be connected to the driven member cable end of another interlocking modules, as shown in Figure 5, driven member cable end 46 places at driven member 40 1 ends are provided with a self-regulation terminal 62, have a cable hole 63 on this terminal 62, cable 26 can pass cable hole 63.A pad 64 that is " U " shape is established in the outside of self-regulation terminal 62, and the two ends of this pad 64 " U " shape place respectively the internal face place of cable hole 63 and the outside wall surface place of self-regulation terminal 62.A screw 66 passes successively pad 64 and is in the part of self-regulation terminal 62 outside wall surface, the hole wall of self-regulation terminal 62 and the part that pad 64 is in cable hole 63 internal faces, be pressed on the cable 26, nut 65 is screwed on the screw 66, push down the corresponding part of pad 64, cable 26 is locked in driven cable line end 46.By the protection of " U " shape pad 64, to the damage of cable 26, guaranteed again that locking was reliable when both having reduced driven member 40 rotation.Certainly, it will be understood by those skilled in the art that cable 26 also can adopt any known mode, is locked on the driven member cable end 46 of driven member 40.
Interlocking modules of the present invention and the interlock that is made of two such interlocking modules above have been described, but interlocking modules of the present invention not only can be used for two interlockings, also can be used for simultaneously three interlockings, namely in the driven member of interlocking modules shown in Figure 3, increase several parts, can realize easily the interlocking of three circuit breakers.Shown in Figure 6ly be an a kind of interlocking modules 300 that can be used for three circuit breakers interlocking.Simple and direct for narrating, component no longer identical with interlocking modules shown in Figure 3 100 in the interlocking modules 300 is given unnecessary details.
In order to realize three interlockings of circuit breaker, as shown in Figure 6, also comprised an auxiliary follower lever 47 in the driven member of interlocking modules 300, this auxiliary follower lever 47 comprises a rotation axis 42, an auxiliary follower lever cable end 48 and an auxiliary follower lever back-moving spring 49.Because the rotation axis 41 this moment of auxiliary follower lever is arranged on an end of auxiliary follower lever, described auxiliary follower lever back-moving spring 49 is torsion spring.As shown in Figure 6, the rotation axis 41 of auxiliary follower lever 47 bodies of rod and driven member 40 links, and rotates moving axis when clockwise rotating at auxiliary follower lever like this, and the rotation axis 41 that can drive follower lever 40 moves downward, and equally also can drive follower lever 40 and move downward.In addition, there are two cables 26 to stretch out from the driving link cable end 24 of driving link 20.
Fig. 7 has shown be made of a kind of structural representation of interlock interlocking modules shown in Figure 6 300 in the situation of three circuit breaker parallel operations.Because the interlocking modules of three circuit breakers is identical, so in the piece mark of Fig. 7, identical rear two digits represents identical parts, hundred numeral then is used for representing the interlocking modules that different circuit breakers is used, namely hundred bit digital are the parts in first interlocking modules of expression of " 3 ", hundred bit digital are the parts in second interlocking modules of expression of " 4 ", and hundred bit digital are the parts in the 3rd interlocking modules of expression of " 5 ".
As shown in Figure 7, when the interlocking that will realize three circuit breakers, interlock comprises three interlocking modules 300,400 and 500, and each circuit breaker links to each other with an interlocking modules.One end of two cables 326 of interlocking modules 300 links to each other with driving link cable end 324, article one, the other end of cable 326 is connected to the driven member cable end 446 of interlocking modules 400, and the other end of another cable 326 is connected to the auxiliary follower lever cable end 548 of interlocking modules 500; Similarly, one end of two cables 426 of interlocking modules 400 links to each other with driving link cable end 424, article one, the other end of cable 426 is connected to the driven member cable end 546 of interlocking modules 500, and the other end of another cable 426 is connected to the auxiliary follower lever cable end 348 of interlocking modules 300; One end of two cables 526 of interlocking modules 500 links to each other with driving link cable end 524, article one, the other end of cable 526 is connected to the driven member cable end 346 of interlocking modules 300, and the other end of another cable 526 is connected to the auxiliary follower lever cable end 448 of interlocking modules 400.
When with breaker closing that interlocking modules 300 links to each other, driving shaft 322 rotates counterclockwise with breaker main shaft, and driving link 320 rotates counterclockwise simultaneously, drives driving link cable end 324 and moves upward, and upwards spur simultaneously two cables 326.Wherein cable 326 pulling driven member cable end 446 move downward, and driven member 440 moving axis 441 that just rotates is rotated counterclockwise like this, and when rotation was finished, driven member 440 was just tactile mutually with the control piece drive ends 434 of control piece 430; The other end of another cable 326 then is connected on the auxiliary follower lever cable end 548 of interlocking modules 500, the auxiliary follower lever cable end 548 of described cable 326 pullings moves downward, auxiliary like this driven member 547 moving axis 542 that just rotates turns clockwise, when rotation is finished, the drive follower lever 540 that clockwise rotates of auxiliary follower lever 547 moves downward, and the control piece drive end 534 with control piece 530 touches mutually just.In this state, the circuit breaker that links to each other with interlocking modules 400 or interlocking modules 500 still can carry out closing operation.
At this moment, if the circuit breaker that links to each other with interlocking modules 400 also carries out closing operation, driving shaft 422 rotates counterclockwise with breaker main shaft, and driving link 420 rotates counterclockwise simultaneously, drive driving link cable end 424 and move upward, and upwards spur simultaneously two cables 426.Wherein the other end of a cable 426 is connected on the auxiliary follower lever cable end 348 of interlocking modules 300, auxiliary follower lever cable end 362 ends of described cable 426 pullings move downward, driven member 347 moving axis 342 that just rotates turns clockwise like this, when rotation is finished, the drive driven member 340 that clockwise rotates of auxiliary follower lever 347 moves downward, and the control piece drive end 334 that just is positioned at control piece 330 touches mutually.In this state, driven member 340 moves downward the on/off switch operation that can not affect the circuit breaker that links to each other with interlocking modules 300.
Simultaneously, the other end of another cable 426 is connected on the driven member cable end 546 of interlocking modules 500, and cable 426 pulling driven member cable end 546 move downward, and driven member 540 moving axis 541 that just rotates is rotated counterclockwise like this.Because during with breaker closing that interlocking modules 300 links to each other, moving downward of auxiliary follower lever cable end 548, made the control piece 547 of interlocking modules 500 touch follower lever 540, at this moment, add moving downward of driven member cable end 546, just drive control piece 530 and be rotated counterclockwise, the emergency brake-dividing device that drives the circuit breaker that is connected with interlocking modules 500 rotates, this circuit breaker can't be closed a floodgate, thereby satisfied three interlock requirements.
When with breaker open operation that interlocking modules 400 links to each other, the driving shaft 422 of interlocking modules 400 clockwise rotates, driving driving link 420 clockwise rotates, driving link cable end 324 moves downward, thereby the driven member cable end 546 that causes interlocking modules 500 is tension no longer, at this moment driven member back-moving spring 545 turns clockwise driven member 540 to reset, this moment is on interlocking modules 500, only there is auxiliary follower lever cable end 548 to spur downwards, but do not affect the motion of control piece 530, therefore, under the effect of control piece back-moving spring 536, control piece 530 clockwise rotates, and the emergency opening state of the circuit breaker that links to each other with interlocking modules 500 is ended, and Interlock Status is removed.That is to say that after the circuit breaker that links to each other with interlocking modules 400 entered gate-dividing state, the circuit breaker that links to each other with interlocking modules 500 can carry out closing operation.
Perhaps, when with breaker open operation that interlocking modules 300 links to each other, the driving shaft 322 of interlocking modules 300 clockwise rotates, driving driving link 320 clockwise rotates, driving link cable end 324 moves downward, thereby the auxiliary follower lever cable end 548 that causes interlocking modules 500 is tension no longer, assisting follower lever back-moving spring 549 that auxiliary follower lever 547 is rotated counterclockwise resets, this moment is on interlocking modules 500, only there is driven member cable end 546 to spur downwards, but do not affect the motion of control piece 530, therefore, under the effect of control piece back-moving spring 536, control piece 530 clockwise rotates, the emergency opening state of circuit breaker of linking to each other with interlocking modules 500 is ended, and Interlock Status is removed.That is to say that after if the circuit breaker that links to each other with interlocking modules 300 enters gate-dividing state, the circuit breaker that links to each other with interlocking modules 500 also can carry out closing operation.
The above describes when the circuit breaker that links to each other with interlocking modules 300 at first closes a floodgate the interlocking process of interlock in detail in conjunction with Fig. 7.No matter it will be understood by those skilled in the art that it at first is which circuit breaker closes a floodgate first, the interlocking of its interlock or releasing process are all similar with said process, do not repeat them here.
Although above the description of interlocking modules of the present invention and interlock is only limited to the situation of two interlockings and three interlockings, but art technology person is appreciated that, if need to interlock to more circuit breaker, the quantity of the quantity that only needs suitably to adjust driven member in the interlocking modules and position and the cable that links to each other with the driving link of interlocking modules can realize.When consisting of the interlock of circuit breaker by this interlocking modules, only according to design spirit of the present invention, the cable that is stretched out by individual driving link cable end in each interlocking modules is connected respectively on the driven member cable end or auxiliary follower lever cable end of other each interlocking modules, can satisfies the interlock requirement of many circuit breakers.
