s3, if a fault lamp is turned on, a fault point of the equipment is checked: removing the fault; when the fault lamp is not on, the manual/automatic switch can be adjusted to be in an automatic state or an automatic state according to the requirement, and a tension control system of the equipment can automatically judge whether the cable is wound or unwound to adjust the tightness state of the cable according to the tension applied to the cable;
s4, when the manual automatic switch is adjusted to be in an automatic state, if the tensile force applied to the cable is just in a set allowable range at the moment, the equipment cannot act;
the pulling force that the cable received is greater than or is less than the range value of setting, and tension system detects the cable too tight or too loose, and equipment can rotate by oneself and tighten up or loosen the cable.
9. The control method of the shore power system for high-voltage cable protection of the large water head wharf according to claim 8, wherein the control method comprises the following steps: the shore power integrated system is an electric control system which converts a 10kV/50Hz power supply into 0.4kV/50Hz power supply to the side shore of a wharf, is connected by a fixed cable reel vehicle placed on a shore base when a boat is connected, and is connected with an electric control system on the shore of the pontoon through a cable reel.
10. The control method of the shore power system for high-voltage cable protection of the large water head wharf according to claim 8, wherein the control method comprises the following steps: the shore power is transmitted to the ship power after the control output cabinet of the shore power control system, and the shore power supply is provided for the ship berthing at the wharf;
the shore power cable is softer than a common high-voltage power supply cable, and the two cables need to be in butt joint conversion through a high-voltage connection box.
