The interlocking device for preventing the grounding switch from being operated during closing according to claim 4, wherein: when the three-station mechanism is in a brake-separating state, the indicating device drives the indicating limiting plate to rotate, and the interlocking limiting plate and the indicating limiting plate are separated from a buckling state.
6. The interlock device for preventing the ground switch from being operated when closing according to claim 2, wherein: when the three-station mechanism is in a closing state, the indicating limiting plate is located above the interlocking limiting plate, the interlocking plate is limited to be moved upwards, then the grounding transmission shaft is completely exposed, and grounding operation on the grounding transmission shaft is prevented.
7. The interlock device for preventing the ground switch from being operated when closing according to claim 1, wherein: the interlocking limit plate and the indicating limit plate are positioned on the opposite side faces.
