Please continue to consult Fig. 1, in order to make the utility model circuit breaker interlocking device in mechanical interlocking, also have electrical interlock, use and reach dual interlock, fully guarantee security reliability, so the side at the mounting panel 42 of described support 4 is provided with at least one sensitive switch 7, described sensitive switch 7 is positioned at the below of pressing plate 51 and the combined floodgate electrical circuit by circuit and circuit breaker is realized being electrically connected, and makes button on the sensitive switch 7 corresponding to the pressing plate 51 of described interlocking rod member 5.
Please in conjunction with Fig. 1, Fig. 2, Fig. 3 and Fig. 4 narrate assembling process of the present utility model: an end of the separating brake blocking lever 53 of the rod member 5 of at first will interlocking and pressing plate 51 are fixing, insert in the through hole of offering on the baffle plate 43 431 in cover upper reset spring 52 backs then, pressing plate 51 is just fallen in the opening of offering on the mounting panel 42 of support 4 421, one end of back-moving spring 52 is conflicted on baffle plate 43, the other end of back-moving spring 52 is conflicted on the pressing plate 51 of interlocking rod member 5, again connecting plate 54 is fixedly connected on the nearly medium position of separating brake blocking lever 53, then the end with combined floodgate blocking lever 55 is fixedly connected on the connecting plate 54, the other end with separating brake blocking lever 53 and combined floodgate blocking lever 55 inserts the two through hole of offering in the bending 44 441 respectively subsequently, in 442, then again sensitive switch 7 is fixedly mounted on the mounting panel 42 of support 4, be inserted in connecting lever 2 in the alignment pin 41 of support 4 by hole 23 then, free to rotate, and the projection 22 on the connecting lever 2 is matched with the pressing plate 51 of interlocking on the rod member 5, at last support 4 is installed on the side plate of circuit breaker operation mechanism, so far support 4, interlocking rod member 5, connecting lever 2 and sensitive switch 7 install.The cover 3 of then will interlocking is installed in the pushnut 1, square hole in the middle of interlocking cover 3 can drive rotates, because pushnut 1 is determined motionless with support 4 relative positions, do corresponding slip in the sliding tray 311 of the interlock plate of setting up on the interlocking latch 21 insertion interlocking covers 3 with connecting lever 2 when being installed on pushnut 1 on the circuit breaker more subsequently 31, so far circuit breaker interlocking device all installs.
See also Fig. 1, Fig. 2, circuit breaker is a released state:
When circuit breaker is in work, tests or removes the position, circuit breaker is a released state, square hole in the middle of the interlocking cover 3 in the pushnut 1 is from the horizontal by certain angle, at this moment, interlocking rod member 5 is because back-moving spring 52 effects are in free state, and the button on the sensitive switch 7 do not interlocked rod member 5 pressing plate 51 compressing in the raw, the normal opened contact of circuit breaker disconnects, normally closed contact is connected, the combined floodgate electric loop is formed the loop by normally closed contact, therefore under this state, allow circuit breaker to carry out electric closing operation.Simultaneously, push pedal 61 on separating brake blocking lever 53 and the separating brake semiaxis 6 is separated, circuit breaker can carry out electric or manual sub-switching operation according to actual needs, equally, lockplate 81 on combined floodgate blocking lever 55 and the combined floodgate semiaxis 8 is separated, and circuit breaker can carry out electric or manual closing operation according to actual needs.
See also Fig. 4, Fig. 5, circuit breaker is an Interlock Status:
Circuit breaker is under the situation of moving process, interlocking cover 3 in the pushnut 1 turns clockwise, square hole to interlocking cover 3 is parallel with horizontal plane, interlock plate 31 transferred to the dextrorotation of interlocking cover 3 and moved downward this moment, because being arranged in the sliding tray 311 of the interlock plate of setting up on the interlocking cover 3 31, the interlocking latch 21 of connecting lever 2 does corresponding slip, the alignment pin 41 that drive connecting lever 2 is convexly equipped with on support 4 is rotated counterclockwise, along with rotatablely moving of connecting lever 2, projection 22 on the connecting lever 2 is with pressing plate 51 past pressing down, the compressing of the button compression plate 51 on the sensitive switch 7 and moving, the combined floodgate electric loop is cut off in the conversion of its normally-open normally-close contact, reaches the anti-combined floodgate interlocking on electric.Because the pressing plate 51 of interlocking rod member 5 is fixedly connected with an end of separating brake blocking lever 53, this moment, separating brake blocking lever 53 compressing back-moving springs 52 also moved downward simultaneously, the push pedal 61 of installing on the end of separating brake blocking lever 53 and separating brake semiaxis 6 contacts, and promotion push pedal 61 rotates, the rotation of push pedal 61 drives separating brake semiaxis 6 and rotates, if be in the "on" position separating brake of will threading off this moment before the circuit breaker, reach separating brake interlocking mechanically.Meanwhile, move downward in a side of the lockplate 81 of combined floodgate semiaxis 8 by the combined floodgate blocking lever 55 that connecting plate 54 fixes with separating brake blocking lever 53, when manual operation combined floodgate semiaxis 8, face 811 on the lockplate 81 that is fixed in combined floodgate semiaxis 8 is withstood on the combined floodgate blocking lever 55, the rotation of combined floodgate semiaxis 8 is limited, thereby guaranteed that combined floodgate semiaxis 8 is not rotatable, reached anti-combined floodgate interlocking mechanically.
