Embodiment
In order to make technical problem to be solved in the utility model, technical scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
Please refer to shown in Fig. 2 to Fig. 8, the preferred embodiment of the active and standby miniature circuit breaker mechanical interlock of the utility model, mainly comprises the first circuit breaker 1 and the second circuit breaker 2 and the interlocking assembly 3 that is arranged between the first circuit breaker 1 and the second circuit breaker 2 that left and right arranges.
The first turning handle 4 and the second turning handle 5 is respectively equipped with at the top of the first circuit breaker 1 and the second circuit breaker 2, pull the first turning handle 4 or the second turning handle 5 can carry out the closed of the first circuit breaker 1 or the second circuit breaker 2 or disconnect, thus realize the closed of electric power loop or disconnect.First circuit breaker 1 and the second circuit breaker 2 are fixed on base plate 7 by mounting guide rail 6 simultaneously.First circuit breaker 1 and the second circuit breaker 2 are connected on mounting guide rail 6.Guide rail card 15 is respectively arranged with in the outside portion of the first circuit breaker 1 and the second circuit breaker 2.Guide rail card 15 is fixed on mounting guide rail 6, for fixing the position of the first circuit breaker 1 and the second circuit breaker 2, prevents the first circuit breaker 1 and the second circuit breaker 2 from loosening.
Interlocking assembly 3 is also fixed on base plate 7.Interlocking assembly 3 comprises supporting bracket 8 and rotor plate 9.Supporting bracket 8 is fixed on base plate 7 by supporting bracket bolt 10.Be provided with through hole 11 at the middle part of rotor plate 9, rotor plate screw 12 is arranged on rotor plate 9 top of supporting bracket 8 rotationally through this through hole 11, and rotor plate 9 can around through hole 11 for axis rotates.Left and right reversed column 13 and 14 is respectively equipped with at the two ends of rotor plate 9.Left reversed column 13 is positioned at the front side of the first turning handle 4 of the first circuit breaker 1 being in closure state, and now, right reversed column 14 is just in time positioned at the front side of the second turning handle 5 of the second circuit breaker 2 being in off-state.Pull the second turning handle 5 or the first turning handle 4, force rotor plate 9 counterclockwise or rotate clockwise by right reversed column 14 or left reversed column 13, thus drive the first turning handle 4 or the second turning handle 5 to have linked together the switching action of electric power loop by the left reversed column 13 or right reversed column 14 being arranged on rotor plate 9 other end.During handoff procedure, the time that turning handle disconnects is before another turning handle is closed.
Referring to shown in Fig. 2 to Fig. 5, assuming that initial condition of the present utility model is: the first turning handle 4 of the first circuit breaker 1 is in closure state, the second turning handle 5 of the second circuit breaker 2 is in off-state, as shown in Figure 2.When electric power loop needs to switch, pull the second turning handle 5, rotor plate 9 is forced to rotate counterclockwise by right reversed column 14, thus drive the first turning handle 4 to link together by the left reversed column 13 being arranged on rotor plate 9 other end, first first circuit breaker 1 disconnects, second circuit breaker 2 is just closed, completes the switching action of electric power loop.
Referring to shown in Fig. 6 to Fig. 8, the first circuit breaker 1 is in off-state, and the second circuit breaker 2 is in closure state.When electric power loop needs again to switch, pull the first turning handle 4, rotor plate 9 is forced to rotate clockwise by left reversed column 13, thus drive the second turning handle 5 to link together by the right reversed column 14 being arranged on rotor plate 9 other end, first second circuit breaker 2 disconnects, first circuit breaker 1 is just closed, completes the switching action again of electric power loop.Now, the utility model is returned to initial condition.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection range of the present utility model.
