。 Figures 1 to 4 show the mechanical interlock device of the circuit breaker of the present invention, and Figure 1 shows a state in which the first circuit breaker and the second circuit breaker are stored in two stacks, one above the other, in a switchboard. Figure 2 is a side view of Figure 1 taken from arrow A, Figures 3 and 4 are the front view of Figure 1.
The figure is viewed from the B-B cut plane. In Figure 3, the first circuit breaker is in the closed state, the crank arm is in the position shown by the solid line, the connecting rod is pulled up, and the second circuit breaker is closed. Figure 4 shows that the first circuit breaker can be placed in the cut-off state in this state.
In the figure, the first circuit breaker is in the disconnected state, the crank arm is in the position shown by the solid line, the connecting rod is pushed down, and the second circuit breaker is in either the closed or closed state in this state. FIG. 5 shows a conventional example, and is a front view showing the entire device with a structure in which two circuit breakers are arranged horizontally, and showing the main parts in cross section. 2...First circuit breaker, 4...Second circuit breaker, 6

Claims

[Scope of utility model registration request]

In a power distribution board in which two circuit breakers are stacked one above the other, the opening/closing shaft for opening and closing the main circuit contacts of each of the two circuit breakers protrudes from the same side of one of the circuit breakers.
When viewed from the protruding side, the crank lever is placed to the left on the protruding part of the opening/closing shaft for the first circuit breaker stacked on the upper tier, and the protruding part of the opening/closing shaft for the second circuit breaker stacked on the lower tier. A crank is fixed with the crank lever to the right, and one end has a round hole and the other end has an elongated hole extending in the longitudinal direction. A mechanical interlock device for a circuit breaker, comprising a connecting rod connected to a lever by a pin.
