Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described in detail.
As shown in Figure 1, the locking of this breaker and release mechanism comprise a base 5, and the upper end of base 5 is provided with a cover plate 1.Base 5 is also provided with snap close 2, microswitch 3, electrical apparatus release 4, push rod 6, spring 7 and magnetic flow convertor 8.
As shown in Figure 2, one end of snap close 2 is securing rod 21, the other end is release lever 22, release lever 22 comprises left dropout portion 23, middle dropout portion 24 and right dropout portion 25 3 part, middle dropout portion 24 is provided with the second draw-in groove 26, the middle part of snap close 2 is provided with a bearing pin 27, and snap close 2 is hinged on base 5 by bearing pin 27.Microswitch 3 is fixed on base 5, and microswitch 3 is provided with actuating rod, and actuating rod contacts with the left dropout portion 23 of release lever 22, and actuating rod outwards can eject under the reset force effect of microswitch 3, and actuating rod acts on release lever 22 and snap close 2 can be made to rotate.Electrical apparatus release 4 is fixed on base 5, and electrical apparatus release is provided with one can the electrical apparatus release iron core 41 (as shown in Figure 4) of rectilinear motion back and forth, and electrical apparatus release iron core 41 is connected in the second draw-in groove 26.
As shown in Figure 3, one end of push rod 6 is provided with bearing pin 61, and push rod 6 is hinged with base 5 by this bearing pin 61, and push rod 6 is provided with a riser 62, riser 62 is provided with a limited step 64, forms the first contact surface 65 and the second contact surface 66 in the both sides up and down of riser 62 upper limit step 64 respectively.Be resisted against on the first contact surface 65 at lock-out state securing rod 21, be resisted against on the second contact surface 66 at released state securing rod 21.Push rod 6 is also provided with a connection piece 67, connector 67 can breaker semiaxis coordinate, promote breaker semiaxis rotate make breaker open operation.Riser 62 is also provided with the first draw-in groove 63, magnetic flow convertor 8 is fixed on base 5, magnetic flow convertor 8 is provided with one can the magnetic flow convertor iron core 81 (as shown in Figure 5) of rectilinear motion back and forth, magnetic flow convertor iron core 81 be stuck in the first draw-in groove 63.One end of spring 7 is fixed on base 5, and the other end of spring 7 is connected with push rod 6.
As shown in Figure 6,7, the locking of this breaker and release mechanism are operationally, when magnetic flow convertor 8 receives the disjunction instruction of controller, the magnetic flow convertor iron core 81 of magnetic flow convertor 8 is got and is driven push rod 6 to rotate clockwise, in rotation process, push rod 6 is stirred the rotation of breaker semiaxis by connector 67 and is made breaker open operation; Simultaneously, the securing rod 21 ridden on push rod 6 first contact surface 65 slips off gradually and departs from push rod 6, now the securing rod 21 of snap close 2 is rotated down in the reset force effect of microswitch 3 actuating rod, withstand on the second contact surface 66 of push rod 6, due to the restriction of limited location step 64, push rod 6 can not oppositely rotate counterclockwise, and so namely enters this mechanism and just enters lock-out state, now can not carry out breaker switching-on operation.
When unlocking after getting rid of circuit breaker failure, unlock by remote de-locking, left unblock and right unblock three kinds of modes.
As shown in Figure 8,9, when carrying out remote de-locking, first by long-range, electrical apparatus release 4 is energized, the electrical apparatus release iron core 41 of electrical apparatus release 4 is moved downward, and electrical apparatus release iron core 41 drives the release lever 22 of snap close 2 to rotate by middle dropout portion 24, and the securing rod 21 of snap close 2 upwards rotates, securing rod 21 is separated with push rod 6, now push rod 6 rotates counterclockwise reset under the effect of spring 7, so namely completes releasing process, now can carry out breaker switching-on operation.
When carrying out left unblock, with manually pinning the 23 times motions in left dropout portion, release lever 22 is rotated, securing rod 21 upwards rotates, and then securing rod is separated with push rod 6, such push rod 6 rotates counterclockwise reset under the effect of spring 7, so namely completes releasing process, now can carry out breaker switching-on operation.Right unblock is substantially identical with left unlocking manner, only namely need complete releasing process with hand by bottom right dropout portion 25, make breaker carry out closing operation.
This breaker locking and release mechanism structure is simple, operating physical force is little, easy to assembly, in use only snap close need be made to swing back and forth can to realize the conversion back and forth of lock-out state and released state, operate very convenient, this locking and release mechanism also have security, advantage that reliability is high.
A kind of breaker provided the embodiment of the present invention above locks and release mechanism is described in detail; for one of ordinary skill in the art; according to the thought of the embodiment of the present invention; all will change in specific embodiments and applications; in sum; this description should not be construed as limitation of the present invention, and all any changes made according to design philosophy of the present invention are all within protection scope of the present invention.
