Embodiment
The present embodiment is a kind of breaker mechanical mutual interlocking gear, and it comprises: base plate (1), support (2), circuit breaker (3), interlocking block (4), hand-screw screw (5), mounting guide rail (6).
As shown in Figure 1, described circuit breaker (3) has two, be respectively the first circuit breaker (3-1) and the second circuit breaker (3-2), described base plate (1) is provided with mounting guide rail (6), the first circuit breaker (3-1) and the second circuit breaker (3-2) is respectively equipped with at the two ends of mounting guide rail (6), the middle part of mounting guide rail (6) is for installing interlocking block (4), described interlocking block (4) top part is provided with the screw hole be fixedly connected with hand-screw screw (5), bottom surface sections is hollow form, the bottom surface sections of interlocking block (4) coordinates with circuit breaker (3), described support (2) top is provided with for the strip elliptical aperture through hand-screw screw (5), this strip elliptical aperture can make hand-screw screw (5) move left and right, to switch the first circuit breaker (3-1) and the second circuit breaker (3-2), two bottom sides is provided with the screw hole for being connected with base plate (1), described interlocking block (4) is inner through being fixed on support (2) after support (2) by hand-screw screw (5), described support (2) is utilized by the screw hole arranged bottom it and is bolted on base plate (1), described circuit breaker (3) and interlocking block (4) are respectively arranged with the stopping means that can mutually block, stopping means on described circuit breaker (3) is handle (3-1-1, 3-2-1), stopping means on described interlocking block (4) is groove (4-1, 4-2), hand-screw screw (5) is for interlocking block (4) horizontally slipping and can lock interlocking block (4) on support (2).
When the first circuit breaker (3-1) and the second circuit breaker (3-2) are all in off-state, interlocking block (4) can horizontally slip on support (2), and two-way power supply is all in off-state, along separate routes no current.
As shown in Figure 2, when the first circuit breaker (3-1) closes a floodgate, the handle (3-1-1) of the first circuit breaker (3-1) has blocked the path that interlocking block (4) is moved to the left, now the first circuit breaker (3-1) is to branch feeding, and the handle (3-1-1) of the first circuit breaker (3-1) can power-off, the handle (3-2-1) of the second circuit breaker (3-2) is locked by the right groove (4-2) of interlocking block (4), can not close a floodgate;
Close a floodgate to the second circuit breaker (3-2), first must disconnect the first circuit breaker (3-1), the handle (3-1-1) of the first circuit breaker (3-1) is in open position, interlocking block (4) is moved to the left, now the handle (3-1-1) of the first circuit breaker (3-1) is locked in off-state by the left groove (4-1) of interlocking block 4, the handle (3-2-1) of the second circuit breaker (3-2) can close a floodgate and power and opening operation, as shown in Figure 3;
Said process can realize the mechanical interlocked of the first circuit breaker (3-1) and the second circuit breaker (3-2).Like this, just guarantee to have a circuit breaker to be in open mode, avoid two-way power supply and input simultaneously and cause Electrical Safety accident.
