The high-voltage cable laying system comprises a high-voltage cable tractor, a plurality of high-voltage cable conveyors and high-voltage cable rollers which are arranged along a laying line, an electric generator for supplying power to the high-voltage cable tractor and the high-voltage cable conveyors, and a control device; and a motor of the high-voltage cable conveyor is provided with a PWM speed regulator electrically connected with the control device.

Description

technical field [0001] The invention relates to the technical field of high-voltage cable laying, in particular to a high-voltage cable laying system and a laying method. Background technique [0002] At present, during the laying of high-voltage transmission cables, one end of the high-voltage cables is generally fixed by a tractor, and the high-voltage transmission cables are pulled and laid by mechanical tension, and the middle part of the high-voltage cables is supported by rollers. When the traction machine is laying high-voltage cables, it is easy to damage the internal structure of the high-voltage cables. Especially when laying long-distance high-voltage cables, the force difference between the inner core copper conductor of the cable and the outer insulating layer is relatively large, and the high-voltage cables are easy to break. Some laying methods play a certain role by installing a high-voltage cable conveyor in the middle of the high-voltage cable to reduce the...

Problems solved by technology

When the traction machine is laying high-voltage cables, it is easy to cause damage to the internal structure of high-voltage cables, especially when laying long-distance high-voltage cables, the force difference between the inner copper conductor of the cable and the outer insulating layer is large, and the high-voltage cables are easy to break

Some laying methods play a certain role by installing a high-voltage cable conveyor in the middle of the high-voltage cable to reduce the difference in the tension between the high-voltage cable jacket and the copper core. For power supply, due to the long distance, there will be a pressure drop, which will cause the speed of the high-voltage cable conveyor at each different position to be inconsistent, and the tension on the high-voltage cable between two high-voltage cable conveyors at different positions is also different. The speed difference causes the high-voltage cable between the two high-voltage cable conveyors to be subjected to excessive extrusion force, which is still easy to cause damage to the high-voltage cable during laying
