High-voltage transmission line stretching and paying-off automatic adjusting method and control system thereof

Abstract

The invention discloses a high-voltage transmission line stretching and paying-off automatic adjustment method and a control system thereof, and belongs to the technical field of high-voltage transmission line stretching and paying-off automatic adjustment. The technical problem to be solved is to provide a high-voltage transmission line stretching and paying-off automatic adjustment method. According to the technical scheme, the method comprises the steps: inputting basic parameters of all tower positions of a pay-off section into a control system, and outputting initial output values of a traction machine and a tension machine through calculation; obtaining a height value, namely a sag height value, of the lowest point of a wire on the whole large-span line of the power transmission lineand sending the height value to a control system; setting a sag movable height range in the control system, wherein in the paying-off process, the control system adjusts the output values of the traction machine and the tension machine in real time according to the change value of the actual sag height, so that the sag height is kept within the set height range all the time; the method is appliedto high-voltage transmission lines.

[0002] In the process of power grid construction, the large-span stretching and setting-out construction is a crucial link. At the same time, this construction operation has relatively strong complexity and construction difficulty, and is easily affected by many external factors.

[0003] The traditional tension pay-off needs to consider technical issues such as the uplift, down-press, and angle of the pay-off tackle brought about by continuous up and down the mountain. Constantly adjust the strength of the traction machine and tension machine, but this manual adjustment is only based on the sag height of the naked eye, and the adjustment strength of the traction machine and tension machine is not the best value

When the tractor or tensioner exerts too much force, the tension on the wire itself will increase, which will easily cause damage to the wire. In severe cases, there will be dangers such as wire breakage and springback.

When the output of tractor or tension machine is too small, it is very easy to cause the wire to slip and jump

The motor will be damaged when the strength of the tractor or tensioner is unbalanced
