Source, the cable that service cable 1 is located at peak level (175 water level of Three Gorges dam zone) or more in bank base is fixed as far as possible, to reduce electricity
The tension of cable top helps to protect cable.
Then service cable 1 is laid along bank base slope, since ramp surface is mostly cement sandstone, if service cable is straight
It connects and is in contact with it, there are cable serious wear when water level fluctuation or folding and unfolding cable, epidermis, the sheath even worn out wind of insulating layer
Danger has some potential safety problems.In order to solve this problem, in the embodiment of the present invention, along slope cabling gantry 5, power supply
Cable 1 is laid along cable testing bridge 5.It is by cable testing bridge 5 that service cable is fixed in a certain range, it is used to support cable weight
Amount, reduces the tension of cable, to protect cable, prevents cable from surprisingly losing.Being provided on the top of cable testing bridge 5 can be rotated
Roller, service cable directly contacts with the roller on cable testing bridge top, active force of the roller in cable when service cable folding and unfolding
Lower rotation can effectively reduce friction, reduce cable abrasion, play the purpose of protection cable.

The automatic deploying and retracting of existing cable, on cable drum 2 installation tension sensor to detect the tension of service cable, tension sensor it is defeated
Outlet connects driving device.When tension sensor detection service cable tension changes, driving device is according to this tension variation
It drives cable drum to rotate with folding and unfolding service cable, realizes the cable drum with SEA LEVEL VARIATION automatic deploying and retracting cable function.
The specific work process of landing stage special intelligent twisted and released of the cable system of the invention are as follows: when the water level descends, power supply electricity
Cable pulling force increases, and tension sensor detects tension variations, and when pulling force is greater than the constant-tension threshold value of setting, (value is a range
Value), driving device drives cable drum rotation to start cable laying, until tension reaches balance；When water level rises, due to extra electricity
The reason of cable, cable stretch reduce, and the cable drum rotation of driving device driving at this time starts take-up, until the tension of cable reaches
New balance.
When SEA LEVEL VARIATION, either cable laying and take-up, dragging is only a part connect with cable drum, arc sag
Service cable, rather than whole cable, therefore the tension that cable is born is smaller, plays a protective role to cable, simultaneously because making
With sensor detection tension variation, it can be achieved that the automatic deploying and retracting of cable, reduces O&M cost.
The driving device of cable drum is driven using frequency conversion+magnetic hysteresis mode, i.e. frequency converter and magnetic hysteresis shaft coupling is, it can be achieved that electricity
Cable tension continuously adjusts, and is provided simultaneously with torque limitation function, and when frequency converter or system jam, magnetic hysteresis shaft coupling can be protected
Card cable smoothly pulled out, rather than it is stuck cause cable to be broken on reel, guarantee the reliable and stable operation of cable drum.

For large capacity power demands, multi-cable is needed when using low-voltage power supply while being powered.Since low-voltage cable is straight
Diameter is thick, there is artificial the problems such as pulling difficulty and inconvenient mechanical traction；Another power supply distance is remote, and it is big that there are pressure drops, power supply quality
The problem of being difficult to ensure.Therefore this system uses 10kV cable power supply, solves problem of pressure drop.
(2) 10kV cable power supply, convenient for the folding and unfolding management of cable.
For large capacity power demands, when 10kV cable power supply, service cable radical is few, and unit cable can meet power supply
Demand；Cable size is relatively small, and twisted and released of the cable is relatively easy.
(3) effective protection and management of cable realizes safety utilization of electric power.
The roller of cable testing bridge shares the weight of cable, can reduce the tension of cable；Cable testing bridge avoids cable and cement
Ground or sandstone directly contact, and reduce friction, help to protect cable skin and insulating layer；According to SEA LEVEL VARIATION, automatic deploying and retracting
Cable, to avoid loose cable；Cable drum uses frequency conversion+magnetic hysteresis driving method, and it is continuous to have cable stretch
It is adjustable and cable also can be smoothly drawn out when guaranteeing unit exception, realize effective protection and effectively management to cable.
(4) automation of twisted and released of the cable reduces manpower O&M cost.
