[0002] In the process of catenary power-off operation, to prevent potential harm to operating personnel from induced current, industry standards require that a vehicle-mounted equipotential line must be installed when operating the car ladder. This measure aims to ensure that operating personnel can safely contact and operate the catenary equipment that has been powered off after the car ladder and catenary equipment reach an equipotential state.

[0003] However, there are some obvious shortcomings in the existing operation process. First, when the car ladder needs to be moved, the operating personnel must manually hang the vehicle-mounted equipotential line. If this step is forgotten, it will directly lead to the risk of injury from induced current when operating personnel contact the catenary equipment, seriously threatening the safety of the operation.

[0004] On the other hand, if the operating personnel forget to remove the vehicle-mounted equipotential line when moving the car ladder, the equipotential line may damage the catenary equipment or pull off the vehicle-mounted equipotential line due to pulling. This physical damage not only may cause damage to the equipment, but also may cause more serious safety accidents, such as causing the car ladder to tip over, the operating personnel to fall from a high altitude, etc., further exacerbating the danger of the operating environment.
